Planetary gear change-speed transmission for vehicles

A planetary gear change-speed transmission for vehicles, which includes input and output means, transmission housing means including a fixed annular surface means, a planetary gear set operatively connected with the output means, a frictional engaging means and a free-wheeling means operatively connected with the planetary gear set, the frictional engaging means being actuable by an actuating piston means arranged in an annular cylinder, the output means driving a controller means, and feed and discharge lines leading to and from the controller means, the improvement comprising:

• a sleeve-like extension provided at the controller means and extending in a direction of the input means of the transmission, the feed and discharge lines to and from the controller means being disposed in said sleeve-like extension, a support flange means for supporting the frictional engaging means, the free-wheeling means and the actuating piston means, said support flange means being inserted into the transmission housing means from the input side thereof, said support flange means having an annular portion secured to a fixed annular surface of the transmission housing means and a sleeve portion at an inner circumference of the annular portion facing the input means of the transmission, said sleeve portion surrounding said sleeve-like extension and engaging at least portions thereof, said sleeve portion being provided at its inner circumference with transfer means for transferring the pressure medium to and from the feed and discharge lines leading to and from the controller means.
