Abstract
A hydraulic brake force regulating system controls the brake system of a vehicle such that substantially the same breaking power is applied to both wheels of an axle despite the presence of a biased load applied to the wheels. A pair of positioning sensors mounted on the axle to detect the level of inclination of the axle. An electronic controller between the positioning sensors and a control valve regulates the hydraulic oil transferred to the wheels on the axle. The electronic controller actuates a device for controlling the control valve based on a signal received from the electronic controller.
Claims6
A hydraulic brake force regulating system for regulating the hydraulic oil transferred from a master brake cylinder of a vehicle to a pair of wheel brakes, each wheel brake being provided for one of a pair of wheels at opposite ends of an axle of the vehicle, the system comprising:
- a pair of positioning sensors mounted on opposite sides of a center portion of a housing of the axle for sensing the inclination of the axle when a biased load is applied to the wheels;
- an electric controller connected with the positioning sensors for providing a signal indicative of the inclination of the housing;
- a control valve comprising an operating lever for controlling the hydraulic oil transferred from the master cylinder to the wheel brakes;
- and
- a valve control means mounted between the electric controller and the control valve for controlling the control valve with the signal from the controller, wherein the valve control means is a rack and pinion system connected to the operating lever.
A hydraulic brake force regulating system for regulating the breaking force applied to each of a pair of wheels brakes, each wheel brake at an opposite end of an axle of a vehicle, the system comprising:
- a pair of positioning sensors mounted on opposite sides of a central housing of the axle to detect the inclination of the axle;
- an electronic controller connected to the positioning sensors for providing a signal indicative of the inclination of the axle;
- a valve for regulating the braking force applied by each of the wheels brakes;
- and
- a controller for controlling the valve based on the signal from the electronic controller such that substantially the same breaking force is applied by both wheel brakes, wherein the controller comprises a rack and pinion system, and a step motor coupled to the signal from the electronic controller for driving the rack and pinion system.
