Stator One-way Clutch Function
The direction of the fluid entering the stator from the turbine runner depends on the difference in the rotational speeds between the pump impeller and turbine runner.
1. When the rotation speed difference Read more Stator One-way Clutch Function
The Propeller Shaft Description
The propeller shaft (on FR vehicles and 4WD vehicles) transmits power from the transaxle/transmission to the differential. The propeller shaft can move up and down in response to the road conditions and Read more The Propeller Shaft Description
What is an Automotive Drive Shaft/Axle Shaft ?
The drive shaft/axle shaft transmits the drive force to the wheel. 1. Drive shaft (Independent suspension type) They must have a mechanism which absorbs changes in the length of the drive shafts accompanying Read more What is an Automotive Drive Shaft/Axle Shaft ?
Synchromesh Mechanism 1 of 2
1. Description
The synchromesh mechanism is used to prevent “gear noise” and to make gear shifting smoother. This mechanism is called “synchromesh” because two gears which rotational speed is different Read more Synchromesh Mechanism 1 of 2
Outline of Automotive Clutch
The clutch is located between the engine and the manual transaxle (manual transmission) and connects and disconnects the engine power by operating the clutch pedal. Thus, the clutch can gradually transmit Read more Outline of Automotive Clutch
Stall Point and Clutch Point
1. Stall point
The stall point refers to the situation in which the turbine runner is motionless. The difference in rotation speeds between the pump impeller and the turbine runner is at a maximum. Read more Stall Point and Clutch Point
Principle of Torque Converter
Transmission of Torque
When the pump impeller speed increases, centrifugal force causes the fluid to start flowing outward from the center of the pump impeller. As the pump impeller speed rises further, Read more Principle of Torque Converter
What is a Torque Converter?
The torque converter both transmits and multiplies the torque from the engine using the ATF (Automatic Transaxle Fluid) into the transaxle (planetary gear unit) as the medium.
The torque converter consists Read more What is a Torque Converter?
Outline of Automatic Transaxle
With automatic transaxle/transmission vehicles, the driver does not need to judge when shifting up and down. The gears are shifted automatically according to the vehicle speed and the amount that the accelerator Read more Outline of Automatic Transaxle
