Abstract
An oscillation is generated in braking oil in hydraulic brake system to make pressure in pipeline vary with wave peak and trough of oscillation. As a result, the brake shoe doing reciprocating movements, which generates a fast instantaneous braking effect between brake shoe and wheel rim.
Description
The invention provides a kind of brake solution oscillation principle in the braking automobile pipeline that makes, be applicable to the hydraulic brake system of self-propelled vehicle.
As everyone knows, adopting the brake fluid line of fluid pressure type brake automobile is a kind of system with certain rigidity, and its brake solution is a kind of incompressible liquid.As in this rigid system, adding an oscillation source, will make whole oil circuit produce vibration, oil circuit pressure will change with crest, the trough of vibration.Because the variation of pressure will make the movement parts-brake shoes on the brake fluid line produce motion, make and produce the effect that similar quick point is stopped, shoe plate locking rim when preventing to brake between shoe plate and the rim.
What anti-lock adopted during the existing techniques in realizing brake is the leakage compensation formula, promptly by leakage pressure is reduced, and compensates liquid then pressure is raise to realize the variation of oil circuit pressure.Because the leakage compensation required time is longer, so action is slower, and because pipeline has a unlatching, closing course, reliability is also lower.The present invention is owing to be to carry out in the osed top pipeline, so reliability has absolute assurance, and oscillation frequency is much higher than mechanical type switching frequency.The shoe plate action is faster, and braking distance is shortened.
In hydraulic brake system, add an oscillator, just can realize the present invention.
