ABSTRACT:
This invention is directed to a wobble-torque hydraulic transmission device which has variable forward and reverse speeds and is also provided with a straight-through drive feature. The device is provided with a coaster brake feature that prevents the device from running away when going downhill. Also, the device is provided with a brake assembly that prevents rotation of the piston-pump means during forward and reverse operation but permits rotation for straight-through drive.
