<p>Anti-spin control systems are useful, for example, in industrial off-road vehicles. It is desirable that such systems exhibit rapid response to adverse working conditions, and be capable of quickly applying braking forces to whichever driven wheel is rotating at a higher velocity at a given time. The instant invention includes an electrical circuit (42) for producing first and second brake control signals having values responsive to a working condition wherein one of the vehicle wheels (10, 12) loses traction and rotates more rapidly than the other vehicle wheel (10, 12). A first controllable valve (50, 52) receives the first brake control signal and responsively controllably engages a brake mechanism (24, 26) associated with the faster rotating wheel (10, 12), while a second controllable valve (50, 52) receives the second brake control signal and responsively controllably moves a brake mechanism (24, 26) associated with the slower rotating wheel (10, 12) from a brake released position to a brake pre-engaged position. Therefore, upon detecting a slippery working condition, each of the brake mechanisms (24, 26) associated with the driven wheels (10, 12) of the vehicle is brought into a state of readiness for immediate braking effort with minimal time delay.</p> |
