Claims4
An anti-lock brake system for wheeled vehicles, said system comprising:
- a brake for each wheel of said vehicle;
- a first control valve manifold in fluid communication with a manual brake actuator and adapted to be in communication with each of said brakes;
- a second control valve manifold adapted to receive fluid from said first control valve manifold and adapted to be in fluid communication with said brakes;
- an electronic control module in electrical communication with said control valve manifolds;
- a speed sensor adjacent each of said wheels and adapted to sense a change of speed of said adjacent wheel and communicate said change of speed to said control module;
- and
- a motor and pump assembly in electrical communication with said control module for conveying brake fluid from said first control valve manifold to said second control valve manifold;
- said motor and pump assembly comprising
- an electric motor, and
- one gear pump adapted to receive brake fluid from said first control valve manifold and transmit said brake fluid to said second control valve manifold.
