IPC: B60T13/14
Filed: 1960-04-25
Abstract: 890,597. Change-speed and clutch control. GENERAL MOTORS CORPORATION. April 25, 1960 [May 11, 1959; Dec. 7, 1959], No. 14381/60. Class 80 (2). [Also in Group XXXIV] In a motor vehicle control system, an hydraulically-operated brake system is connected through a one-way check valve 70 to an element 54 movable by liquid pressure in the brake system to disengage the vehicle transmission and the check valve 70 is opened only by substantially full brake application. The wheel brakes 20 are applied by pressure from a pump 4 under the control of a foot-brake valve 10. In a control valve 30 the valve element 54 has a land 58 which normally connects fluid pressure inlet 44 with outlet port 46 to the gear clutch valve 33 of the transmission and a cone land 60 which normally covers exhaust 50. When the pressure in the pipe 18 corresponds to substantially full brake application the ball check valve 70 is lifted so that fluid pressure against the piston head 56 moves element 54 to the right. Valve land 58 closes inlet port 44, and land 60 connects outlet 46 to exhaust 50. Pressure is no longer supplied to pipe 32, but the latter is connected to exhaust 50 and the transmission is disconnected. The valve 33 has conduits 34, 36 and 38 which lead to liquid motor-actuated disc clutches or brakes for the gears. When the brakes are taken off and the pressure supplied to the wheel cylinders drops below a certain value, liquid leaks back past the lightly loaded ball valve 72, and the spring 62 in the control valve 30 returns the valve element 54 to the left to allow communication from pump 24 to valve 33 to be resumed. In a second embodiment, Fig. 2 (not shown), the by-pass valve 72 for the one-way check valve 70 is replaced by a bleed restriction.
