Title: Improvements relating to braking apparatus for vehicles
IPC: B60L7/24
Filed: 1934-06-26
Abstract: 437,464. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Craig, J. F. ; 49, Beverly Road, Upper Montclair, New Jersey, U.S.A.) June 26, 1934, No. 18861. Conven-. tion date, June 27, 1933. [Class 103 (i)] [See also Group XXXVII] In brake apparatus for vehicles comprising an electric and a fluid-pressure brake, both controlled by a driver's valve, the diminution of the electric braking with the speed of the vehicle produces gradual increase in the braking force of a fluid pressure brake which is controlled by a self-lapping driver's valve. The driver's handle 60 operates a shaft 59, 61 operating switch arms 11, 12, Fig. 2, controlling the regenerative brake and a cam 57 controlling the fluid pressure brake. To initiate a brake application, the arm 60 is turned to close the circuit for the regenerative brake by arms 11, 12 through the vehicle motor 4 and a solenoid 26, controlling the fluid-pressure brake, and which moves a piston 22 away from a lever 45 adapted to be moved towards the piston 22 by cam 57, which engages the spring plunger 46 carrying the lever. As the speed and regenerative braking decreases the solenoid releases the piston 22 to the left under the pressure of spring 30 until it engages the lever 45 and exhaust valve 34 is thereupon closed and supply valve 19 is opened to supply the brake cylinder 3 and pressure fluid in chamber 14 acting on the piston 22 recloses the valve 19 to lap position. The switch arm 11 controls a resistance 9 controlling the regenerative brake. In a modification, the apparatus is shown combined with an eddy current brake which may be energized from the electric trolly wire of the vehicle. This brake is also controlled by an arm on the driver's valve handle and the circuit of which is adapted to maintain closed a spring switch in the circuit of the regenerative brake and solenoid 26. If the eddy current brake circuit is interrupted for instance by the electric trolly wheel leaving the wire, the switch is released to break the circuit of the solenoid 26 and cause the fluid-pressure brake to be applied. In a further modification, the braking force varies according to load, a variable resistance being included in the circuit of the motor 4 and the coil 26, controlled by an arm operated by parts of the vehicle moving relatively when the load varies. In an arrangement in which the brake cylinder is supplied with fluid by an emergency valve operated by venting of an emergency pipe, a switch in the circuit including coil 26 is opened by venting of this pipe so that the driver's valve can be operated to supply the brake cylinder if the emergency valve fails.
