Title:
DRIVING APPARATUS FOR TRANSMISSION
Document Type and Number:
Japanese Patent JPS61274153
Kind Code:
A
Abstract:
PURPOSE:To smoothly operate a synchromesh mechanism of the driving apparatus of an automatic transmission for a large-sized car by adjusting the transfer time of a piston and the shift force by controlling the electromagnetic three-way valves for introducing and discharging the compressed air to and from the both sides the pressure cylinder in relation to each other. CONSTITUTION:A piston PS for driving the shift lever LV of a transmission is installed into a pressure cylinder C. Vent holes P1 and P2 are formed onto the both sides of the pressure cylinder C. Electromagnetic three-way valves SL1 and SL2 are connected to these vent holes P1 and P2, and compressed air is introduced into the cylinder C from a tank R, or the compressed air is discharged into the atmosphere from inside the cylinder C. The electric conduction time is controlled in relation to the both electromagnetic three-way valves SL1 and SL2, and the smooth operation free from the generation of gear squeak is obtained by adjusting the transfer time of a piston and the shift force.
