What is an Automotive Gear Housing
1. Description
The piston in the power cylinder is positioned on the rack, and the rack moves due to fluid pressurized by the vane pump acting on the piston in either direction. Fluid pressure leakage Read more What is an Automotive Gear Housing
Operation of Automotive Gear Shift
Each gear condition is explained using the solenoid valves and shift valves.
1. 1st gear
For gear shift from neutral to 1st gear, the fluid passage to C1 is opened by switching the manual valve. Read more Operation of Automotive Gear Shift
Types of Planetary Gear Unit
There are various types of planetary gear units. Here, typical planetary gear units are:
1. 3-speed + O/D type (FF vehicles)
By combining a 3-speed planetary gear unit with an O/D gear unit, four Read more Types of Planetary Gear Unit
What is Overdrive Gear Unit?
The overdrive gear unit is an independent planetary gear unit with a gear ratio less than 1.0 (approx. 0.7-0.8). It is combined with a conventional 3-speed planetary gear unit and is equivalent to the Read more What is Overdrive Gear Unit?
What is Planetary Gear Unit?
In automatic transaxle vehicles, the planetary gear unit handles deceleration, reverse, direct connection, and acceleration. The planetary gear unit consists of the planetary gears, clutches, and brakes. Read more What is Planetary Gear Unit?
Automotive Gear Shifting Mechanism
1. Construction
The shift and select lever shaft are set at right angles to the fork shafts on top of the transaxle case. A double-meshing prevention mechanism and reverse gear mis-shift prevention Read more Automotive Gear Shifting Mechanism
