Title: SERVO UNIT FOR BRAKE SYSTEMS WITH ANTI-BLOCKING AND/OR ANTI-SLIP CONTROL
Abstract:
Disclosed is a vacuum-brake servo unit with a connector (23) for the vacuum-line connection pipe (2) and the non-return valve (3). The connector (23) is designed as a housing for a sensing device which monitors the position of the diaphragm disc (16) inside the servo cylinder (15). The sensing device consists of a pin-shaped probe (22) which turns a gearwheel (9) by means of a flexible toothed rack (6). The gearwheel turns a current take-off (12) on an ohmic resistor (35). The voltage generated in this way provides information on the position of the membrane disc (16) inside the servo cylinder (15). Careful choice of components, component design and component matching, and the careful assembly of these components gives a compact unit whose dimensions do not exceed those of a conventional vacuum-brake servo unit. The installation requirements for the unit are thus reduced. The servo unit can be used in any type of installation.
