A pair of vehicle driving wheels (8), (9) powered by a drive shaft (10) through a differential (11) can experience difficulties when one of the two differentially driven wheels (8/9) loses traction. The differential (11) directs power to the wheel that is slipping and the wheel with traction remains stationary. Anti-spin devices have been developed but often produce an abrupt transfer of the driving power to the wheel having traction. The anti-spin apparatus of this invention includes an electrical control circuit (24) and sensors (20), (21) for generating a slip signal representing the speed difference between the wheels (8), (9), and includes a modulated hydraulic reducing valve (30), (110) for actuating the brake (15/15') on the faster rotating wheel (8/9) and a hydraulic modulating control valve (29) connected to the reducing valve (30), (110) and actuated by the slip signal. The reducing valve (30), (110) varies the braking force applied to the faster rotating wheel in accordance with the difference in rotational speeds between the wheels (8), (9). |
