Title:
TRANSMISSION WITH BUILT-IN BRAKE FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2011/104930
Kind Code:
A1
Abstract:
Provided is a transmission with a built-in brake for vehicles, which can prevent cracks from occurring in a hydraulic pipe that supplies pressure oil to a hydraulic piston, by providing the hydraulic piston and the hydraulic pipe to a stationary member. A cylinder chamber (52), which has an opening that faces a pushing arm provided on a transmission case cover plate (2), houses the hydraulic piston (61) such that the piston is brought into contact with a rear-facing arm part (71b) of a pushing arm (71), thereby allowing the pushing arm (71) to rotate. Additionally, the hydraulic pipe (56) that supplies pressure oil to the cylinder chamber (52) is connected to the cover plate (2).
