Understanding Differences in Automotive Differentials WeberAuto 2021-01-28 | See 11 different types of automotive differentials and learn how they work. This video is intended for students in the AUSV 1220 Manual Drivetrain class at Weber State University with Professor John D. Kelly. CORRECTIONS:1. The differential I called a "Detroit Locker" is not a Detroit Locker. It is just an Eaton Posi Limited Slip differential. A Detroit Locker uses dog teeth and is a truly locking differential. Thank you goes out to Keith MacDonald for catching my error.2. I did not adequately explain how the clutch packs of a limited-slip differential are applied. The simple rotation of the side gears versus the differential pinion gears does not cause clutch packs to apply, otherwise, the clutches would apply when turning corners at low load (low torque). Torque from the engine (or another propulsion source) is necessary. The more torque you supply to the differential side gears the higher the force on the angled (ramped) teeth, the higher the force on the clutch packs. Thank you to several viewers for pointing out my omission.3. There is more than one style of Torsen differential. See the JTEKT Corporation's website for more information jtekt.co.jp/e/products/lsd.html 4. I incorrectly described the operation of the original 1956 Dana limited-slip differential. The pinion pins on the original Dana differential have tapered ends. The pins sit in four V-shaped ramps in the differential case. Under a load, the differential case applies rotational torque to the pinion pins causing them to slide up the V-shaped ramps. This action applies outward force to the side gears and the clutch packs. Thank you to several viewers for pointing out my error.TIMELINE0:00 Start0:08 Introduction0:32 Open Differential3:55 Power flow through a differential6:51 Side gear backlash control9:09 Differential Demonstration10:21 MUST SEE Differential Equations13:12 Automotive differential history14:44 Dana Corporation's 1955 invention of the automatic locking differential15:33 Various names for Dana's locking differential17:23 See a 1963 Chevrolet positraction differential with clutch packs24:00 How rotating gears apply a clutch pack26:35 Why limited-slip additive may be required for a clutch-type differential28:46 See a 1970s era GM positraction differential with clutch packs29:40 See a 1984 Chevrolet Corvette Limited-Slip differential with clutch packs30:02 See a 2012 Eaton Posi Limited-Slip differential with clutch packs34:00 MUST SEE See a worn out 2010 Chevrolet Camaro SS Limited-Slip differential with clutch packs38:00 See a broken 2005 Jeep Wrangler Rubicon Torsen Type B style limited-slip differential with an air locker43:51 MUST SEE See the pieces of a Torsen Type B style differential and see how it works48:03 See a 2002 Toyota Tacoma Electric Locking Differential51:00 See the Eaton Detroit Trutrac (Similar to the Torsen Type B differential design)49:55 See a spool with no differential action53:40 See a Mini-Spool and how to install it56:35 See the Eaton Locker and learn how it works1:00:45 Final wrapupABOUT US:Weber State University (WSU) Davis Campus - Automotive Technology Department - Transmission Lab.

Understanding the Toyota RAV4 Hybrid WeberAuto 2021-01-23 | See the amazing hybrid transaxle used in the 2019 - 2022 Toyota RAV4 Hybrid. Learn how this incredible transaxle functions in all nine modes of operation to help its sophisticated 2.5L engine deliver almost 40% brake thermal efficiency (BTE) for maximum fuel economy. This transaxle is also used in the 2018 and above Camry Hybrid, Avalon Hybrid, Lexus ES300h hybrid, and 2021 Venza Hybrid.Corrections and Additions:1. Addition: In EV mode, sling lubrication from gear movement is provided to drip channels that feed bearings, gears, and stator cooling. The RAV4 Prime uses an external electric oil pump for use in EV mode. 2. The 2021 Toyota Venza Hybrid also uses the P710 transaxle.3. Correction: At 27 minutes: In overdrive with MG1 spinning backward, the ICE RPM should be less than when it is in direct drive. I incorrectly said the ICE RPM was higher.4. Correction: The BTE chart at 23:06 is the wrong one for this ICE, it is for the non-hybrid ICE variant known as A25A-FKS (The related experiment is done by EPA, which provides all the details), while the engine for the Hybrid RAV4 is A25B-FKS with a slightly higher peak efficiency to 41%. The BTE plot of A25B is different from the A25A, with lower maximum torque, and a much larger high-efficiency area (it reaches 38% efficiency at 80 Nm until 2500 RPM), and the peak efficiency point/area is shifted to the left/downside.

The internal combustion engine (ICE) will operate at its most efficient rpm for the torque required to propel the vehicle. The motor is forced to rotate by the countershaft. The motor can draw power from the battery to help the engine supply torque to the countershaft (parallel hybrid operation), or it can act as a generator to supply power to the battery. Engine-only mode can occur at speeds as low as ~70.8 km/h (~44 mph).- Mode 3, E-CVT. At higher vehicle speeds, the overdrive clutch is disengaged. The generator provides power to the motor (series hybrid operation), to the battery, or to both depending upon the battery state of charge, motor load, and other factors.TIMELINE:0:00 Start0:12 Introduction0:25 Vehicle Usage0:51 Three modes of operation1:42 Mode 1 - Electric Vehicle (EV) Mode1:56 Two Oil Pumps2:14 Final Drive and Driven Gears3:28 Final Drive gear ratio = 65/19 = 3.421:1 (CR-V 66/17 = 3.882:1)4:21 Counter Shaft Gear5:22 Motor Drive Gear and shaft6:30 135kW Motor power and torque ratings7:17 Motor shaft gear to countershaft gear ratio = 54/22 = 2.455:17:53 MUST SEE: Motor shaft gear to final drive gear ratio = 8.398:1 (CR-V 9.530:1)9:30 MUST SEE: Regenerative braking gear operation10:20 Mode 2 - Engine Only Mode11:42 How the engine is connected to the countershaft14:00 MUST SEE: Overdrive clutch pack demonstration16:00 Overdrive gear to countershaft gear ratio = 54/67 = 0.8059:117:00 Overdrive gear to final drive gear ratio = 2.757:1 (CR-V 3.129:1)18:18 Power Generation18:38 Input shaft gear to generation drive gear ratio = 39/76 = 0.513:119:15 106kW Power generator rotor20:35 Final Assembly of parts - Parking Gear and Pawl22:04 Mode 3 - E-CVT Mode22:40 MUST SEE: Series Hybrid operation23:45 Wrap upABOUT USWeber State University (WSU) Davis Campus - Automotive Technology Department - Advanced Vehicles Lab.

Electrically - Electrical current is run through a copper coil of wire creating a strong electromagnetic field. This magnetic field pushes or pulls on a spring-loaded plunger inside the solenoid2. Mechanically - A spring-loaded plunger inside the solenoid is used to seat a metering ball or valve to block the flow of fluid. 3. Hydraulically - A metering ball or valve is used to block the flow of fluid. Fluid pressure increases when the ball is seated and decreases when the ball is unseated.On-Off solenoids are used to allow fluid flow or block fluid flow but have no ability to create a variable fluid flow (variable fluid pressure). Pulse-Width Modulated (PWM) solenoids are used to create a variable fluid flow (variable fluid pressure). This is used to control fluid pressures, shift feel or shift quality, and control the slip rate of the torque converter clutch and other clutches inside an automatic transmission.Questions for Teachers:1. What are the three different ways a transmission solenoid must work? 2. Give an example of what an on-off solenoid is used for in an automatic transmission? 3. What does the solenoid click test indicate about the condition of the solenoid? 4. Can a solenoid pass the "click test", but still not operate properly? 5. According to the cutaway of an on-off solenoid view in the video, does the fluid exhaust when the solenoid is on or off?6. Why are Pulse-Width Modulated (PWM) solenoids used in automatic transmissions? 7. What advantage does a PWM solenoid have over an On-Off solenoid? 8. How do PWM solenoids create a variable fluid pressure? 9. According to the graphs in the video, what does a 40 percent duty-cycle mean? 10. According to the graphs in the video, does zero amps of current equal a high or low fluid control pressure? 11.

When using an EVSE compliant AC charging station or cord set, this equipment (EVSE) is not technically considered a charger. Instead, it passes the AC power to the vehicle's on-board charger, where it is converted to DC power to charge the vehicle's battery.2. Control Pilot (CP) Contact #4. - For AC Level 1 and AC Level 2 charging, the vehicle does not signal the EVSE how much current it needs. Instead, the external equipment (EVSE) signals the vehicle how much current it is capable of providing. Next, the vehicle's on-board charging module takes whatever amount of current it needs up to that limit.- For DC Level 1 and AC Level 2 charging, the off-board charger signals to the vehicle that Power Line Communication (PLC) is necessary. Using PLC over the Control Pilot (CP) circuit, the vehicle's on-board power line communication module tells the off-board DC charger how much current to supply to charge the vehicle's battery.3. Proximity Detection (PD). Contact #5 of the J1772 charge coupler (CCS Receptacle) uses Proximity Detection (PD), not Proximity Pilot (PP). Proximity Detection detects the connection to the vehicle (as described in the video). Proximity Pilot (PP) is not used in the USA; it is used in some other countries where the charging coupler cable from the EVSE to the vehicle can be swapped to another cable that may or may not be able to carry the same current. The Proximity Pilot signal indicates how much current the cable can handle.4. I have updated my graphic of the J1772 DC Level 2 Charge Coupler.

"Grey coating is an insulator, to prevent circulating currents through the bearings from any slight imbalance in the magnetic field in the motor. there is a single bearing that is grounded ( the shiny one) to prevent charge build-up on the rotor and a flashover to the frame, but the rest have to be insulated so they do not have a shorted turn through the frame that can cause a high circulating current through the bearings that rapidly erodes them through arcing. There are current paths for this current via things like the output shafts and the selector forks, but they probably assumed that being long thin wall section steel assemblies, this long path would both keep the current low enough not to cause any major extra wear, and also the long output shaft would be mostly self-canceling field wise as well.A lot of larger electric motors handle this with one end having coated bearings, or they make them with ceramic bearing balls inside, or just make both sides with insulated bearing mounting frames, and provide a grounding carbon brush assembly to handle shaft grounding. A drawback of the coated bearing is that you have to ensure that there is absolutely no damage to the coating on the outside and the side facing the frame so that there is no metal-to-metal path. However, depending on the exact coating applied, this coat can be both insulating and tougher than the steel of the bearing itself. grey would point to a spray-on ceramic coating, probably vacuum-deposited before final bearing assembly or applied as a plasma coating."Shift Lever and Actuator system update:The shift lever sends a request to a chassis control module (CCM) for the trans range desired. The CCM commands the shift actuator to move the mechanical linkage to the desired position. The internal mode switch (position sensor) inside the trans sends a signal verifying the current gear range selected. The systems also have a "default to park" option when a malfunction occurs which will prevent vehicle movement until the fault is repaired.

Leaf EV vs Bolt EV - Expected Li-Ion Battery Life WeberAuto 2018-03-18 | See what the 2018 Leaf owner's manual tells us about Li-Ion battery life. CORRECTION: I was wrong, there is no airflow through the battery from the passenger compartment. According to the owner's manual, the climate control system can come on while charging, but it does not say why. Maybe it is because the battery gets too hot and heats up the passenger compartment. The Leaf battery is inside a sealed housing under the vehicle.

The fourth mode (Electric Only Combined Engine On) is a series-parallel mode.The 2nd generation Volt's 5ET50 transaxle has 5 modes of operation. Two modes are electric only, one mode is a series-hybrid mode, and the Two remaining modes (series-parallel) allow the ICE to contribute torque to the wheels through the planet carrier of the input gear set. This transaxle is used in a Malibu Hybrid with only 4 modes (they removed the series mode). **1st generation Volt battery. If an individual cell is rated at 55.5Wh (using units of measure) Power (Wh) = EMF (V) x Current (A), then the current rating would be Wh/V = Ah. So 55.5Wh/3.7V = 15 Ah rather than the 55.5 Ah I mistakenly said/displayed in the video.This is the first is a series of videos on the 2 generations of the Chevrolet Volt. This episode covers the removal and detailed reassembly of the 355.2-Volt battery and battery relay assembly from a 2018 Chevrolet Volt. The 2016-2018 Chevrolet Volt batteries are the same. The 2011-2015 Chevrolet Volt battery is similar but has some minor differences. ABOUT USWeber State University (WSU) Davis Campus - Automotive Technology Department - Advanced Vehicles Lab.
