Abstract

1,248,787. Anti-skid control systems. MULLARD Ltd. 13 Dec., 1968, No. 59524/68. Heading F2F. In an anti-skid brake system fluid is bled is bled into a reservoir on wheel-lock and pumped back into the system when the wheel accelerates again. A number of criteria are recited for relieving and restoring brake pressure in accordance with various states of deceleration and speed of the wheel, singly or in combination according to the results required. As shown diagrammatically brake 7 acts on wheel 6 having a cam 14 driving a scavenging pump 13 and a wheel speed sensor 9. When a critical value of wheel deceleration due to braking is detected, the control unit 10 energizes solenoid valve 11 to bleed pressure fluid into the “anti-lock” unit closing valve 22 as fluid passes into the reservoir 26 moving piston 24 to the left so that restrictor 27 enters the brake supply passage. When a suitable wheel acceleration is detected the solenoid valve closes allowing valve 22 to open and fluid is pumped back into the brake pressure line. An anti-lock unit may be provided for each wheel, or one for the front pair and one for the rear pair. Modifications. (i) The solenoid current may be used to vary the valve-loading (instead of opening it) so that it acts as a pressure relief valve causing a “tail-off” in pressure as the brakes are applied hard. (ii) The solenoid may control a two-way valve admitting fluid to a differential piston between the master-cylinder and the brake Fig. 2 (not shown); the connection pipes (4), (15), (20), going to the antilock unit as in Fig. 1. (iii) The differential piston may be replaced by a spring-loaded piston valve allowing a rapid increase of brake pressure to just under the locking valve when the wheel is released, Fig. 3 (not shown).
