Abstract

The utility model relates to a self-control anti-lock brake disk, belonging to the vehicle safety brake technical field, which utilizes a brake clip to clip a brake disk to generate friction torque to decelerate vehicle. The utility model is characterized in that the brake disk is composed of two round disks between which a slide block and a spring are arranged. On a preset lock critical point, the slide block can change the thickness of the two disks to change the friction torque of the brake clip on the disks, while the discontinuous friction torque can effectively reduce speed and avoid locking wheels. The utility model is different from traditional ABS with better effect.

Description

Autocontrol ABS (Anti-lock Braking System) dish

Technical field:

The utility model is an autocontrol ABS (Anti-lock Braking System) dish, and what relate to is safety arrestment technology in the vehicle.

Background technology:

The ABS anti-lock technology of using on the automobile is the actuating unit with computer modulated pressure or air pressure at present, and what high-frequency was interrupted implements braking to brake disc, and popular theory is exactly high-frequency some brake.So-called a few passage is exactly how to use several loops, removes to control front vehicle wheel or rear wheel, is to control respectively or together control or the like.This scheme needs one to overlap computer program accurately, sensitive failure-free power element, and the own special quality guarantee of device (comprising braking liquid).The total system is very complicated, causes with high costsly, can not popularize.During manipulation, call in addition on the stretcher and uncomfortable existing picture such as tremble.

Summary of the invention:

The utility model provides a simple wheel anti-lock scheme.

Itself all has centnifugal force the object of any rotation, and the size of centnifugal force, is to change along with the height of rotating speed.See accompanying drawing 1,2,3,4,5.Basal disc 1 is the steel disc that is fixed on the semiaxis or on the wheel hub, and during automobile normal running, the slide block 3 on the basal disc 1 must be subjected to a centnifugal force, adjusts the pulling force of extension spring 4.During less than N revolutions per second (this value can artificially be set, and claims this value to be the locking transformation point later on), slide block 3 just breaks away between floating plate 8 and the basal disc 1 in wheel speed.During greater than N revolutions per second, slide block 3 embeds between two dishes, 8 and 1 edge in wheel speed.During automobile normal running, wheel speed is far above this critical value, and slide block 3 is embedded between two dishes, 8 and 1 edge all the time.Glancing impact two jaws 11 do not open, and do not contact with 1 with two dishes 8, do not have the friction force generation.When stepping on brake pedal, two jaws 11 are closed under hydraulic pressure, clamp 1 three members of floating plate 8 slide blocks, 3 basal discs simultaneously, and consequent friction force makes car retardation.When wheel speed was reduced to less than critical value, the centnifugal force of slide block 3 diminished, and when going to lower part, the slide block 3 between two dishes 8 and 1 is pulled out in extension spring 4, and three members become two members, total less thick (see figure 5).Two jaw desires clamp but are stopped by the spacing push rod 12 on the jaw, make brake clamp and brake disc no longer include rigid friction force.After wheel lost friction force, wheel speed must increase.Centnifugal force makes slide block 3 throw away again, and is embedded between two dishes 8 and 1 by the lower part of brake disc.The slide block 3 that embeds when going to the first half and the jaw by narrowing down, because of thickness be wider than jaw just rigid push through jaw, the rigid friction force that produces.Wheel speed is reduced.Slide block 3 is on transformation point, and between turnover two dishes 8 and 1 so repeatedly, the just interrupted friction force that produces has promptly guaranteed the reduction speed of a motor vehicle, has not guaranteed armful not the extremely purpose of wheel again.

Above-mentioned working process can be summarized as follows: the speed of wheel speed changes centnifugal force, the centnifugal force that changes makes slide block produce displacement, the slide block of displacement changes the thickness of brake disc, the thickness that changes intermittently produces friction force, interrupted friction force makes car retardation embrace not dead wheel again, and a slide block has played four liang of effects that control is very heavy.The difference of this programme and former traditional ABS scheme is that former scheme is by the interrupted friction force control wheel that produces of brake clamp.Be the brake clamp active, wheel is passive; This programme then is to be cooperated with brake clamp by wheel, the interrupted friction force that produces, and the control wheel is the wheel active, brake clamp is passive.The principle of work of two schemes is opposite fully, and is completely different.

The beneficial features of this mechanism is:

1, pure physical construction does not have any electric and electronic technology, can be made into an accessory independently.

2, can work as the conventional brake device and use, can bring into play the anti-lock function again, need not anyly change.

3, because of there not being computer program, can arbitrarily be installed on the various vehicles

4, cry and chattering can not appear in this mechanism.

The specific embodiment:

Basal disc 1 is the disk of a steel, is equivalent to conventional brake disc.It bears whole brake torques, on the circumference of the side on the basal disc 1, fix the equidistant chute 2 of a circle, movable sliding block 3 is arranged in chute 2, and an end of extension spring 4 hangs on the slide block 3, and the other end is fixed on the pin 5 on the basal disc 1, slide block 3 extension spring 4 when no centnifugal force pulls to the core place with it, Luo bolt 6 is fixed on the basal disc 1, arranges with chute 2 is equidistant at interval, is with spring 7 on Luo bolt 6.Floating plate 8 also is a steel disc, and the circle circular hole 9 bigger slightly than Luo bolt 6 arranged on it, by circular hole 9 floating plate 8 usefulness mothers Luo 10 is fixed on the Luo bolt 6, and floating plate 8 can be axially movable on Luo bolt 6.When the edge of floating plate 8 is braked pincers 11 clampings when sloping inwardly, spring 7 can make the gap of lower part (brake clamp all is the to be positioned on the first half usually) floating plate that is not held 8 and basal disc 1 at maximum position, to guarantee slide block 3 zones that free in and out between two dishes 8 and 1 is arranged.After this brake disc is assembled into an integral body, be an independently accessory,, be fixed on the semiaxis or on the wheel hub by 1 mounting hole 13 on the basal disc.

Be fixed on the brake clamp 11 on the vehicle frame, be the braking element of routine.Difference is on the movable arm of two jaws, has all increased a spacing push rod 12, in order to the stroke of restriction jaw.The method of adjusting push rod 12 length is, when two jaws clamp floating plate 8 slide blocks 3 basal discs 1 three members, adjust between two push rods the gap less than the thickness of slide block 3 get final product,
