Abstract
The present invention relates to a hydraulic wheel brake which is composed of a front brake shoe, a rear brake shoe, a brake drum, a brake bottom plate, a pull rod, a connecting rod, a return spring, etc. The present invention is characterized in that the brake shoe is fixed on the brake bottom plate by a supporting pin; the brake bottom plate is loose sheathed on a semi-shaft casing tube; a positioning shaft shoulder on the semi-shaft casing tube and an enhancing sleeve axially position the brake bottom plate. The present invention can effectively increase vehicle brake force. Thus, the braking force of a hydraulic brake system can satisfy the braking need of middle and heavy duty vehicles; the pneumatic braking disadvantages for the middle and heavy duty vehicles are solved; power consumption is reduced and energy is saved. The present invention has the advantages of simple structure, reasonable brake shoe stress and even abrasion; the present invention has a certain braking antiblocking function and is favorable to driving safely.
Description
The present invention relates to a kind of fluid pressure type car side brake, belong to automotive field.
Existing automobile drum car side brake, its braking force generally derives from hydraulic pressure or air pressure, in hydraulic brake system, the size of its braking force depends on that people give the power on the brake pedal, and in, on the heavy motor vehicle, people give the needs that power on the brake pedal is difficult to satisfy automobile brake, mostly adopt Pneumatic braking system.In Pneumatic braking system, its propulsion source is an automotive engine, and driving engine drives air compressor and produces high pressure air, is controlled the braking force of car side brake by corresponding valve, compressed air brake cylinder, actuating unit by the position of stretcher.This is complex structure not only, and its air compressor also will consume sizable engine power, causes energy dissipation.
The purpose of this invention is to provide a kind of augmented wheel brake, it can increase the braking force of automobile effectively, during thereby the braking force that makes hydraulic brake system satisfies, the requirement of heavy motor vehicle braking, in having solved, heavy motor vehicle is because the bigger pedal force of needs haves no alternative but adopt the present situation of compression air brake.
The present invention can realize by following measure: forward and backward brake shoe brake cheek, be fixed on the back-plate by corresponding rest pin, and braking negative pine is enclosed within on the axle tube, and the location shaft shoulder and reinforcement cover on the axle tube carry out axial location to back-plate.
The present invention is described in further detail below in conjunction with the constructional drawing of augmented wheel brake and schematic diagram.
Fig. 1 is the constructional drawing of augmented wheel brake
1, fore brake 2, pull bar 3,4 connecting rods 5, brake wheel cylinder 6, back brake shoe brake cheek 7, pull back spring 8, wheel hub 9, brake wheel 10, reinforcement cover 11, back-plate 12, axle tube 13, semiaxis 14, rest pin
Forward and backward brake shoe brake cheek 1,6, be fixed on the back-plate 11 by corresponding rest pin 14 and brake wheel cylinder 5, back-plate 11 pines are enclosed within on the axle tube 12, the location shaft shoulder is arranged on the axle tube 12, reinforcement cover 10 is fixed on the axle tube 12 by flat key, and back-plate is realized axial location by the location shaft shoulder and reinforcement cover 10, and reinforcement cover 10 is hinged with pull bar 2, the other end of pull bar is connected with connecting rod 3,4, and the other end of connecting rod 3,4 and brake shoe brake cheek 1,6 are hinged.
Fig. 2 is the schematic diagram of augmented wheel brake reinforcement
When running car was braked, the thrust T that wheel cylinder 5 produces overcame the pulling force P of return spring 7 Be pressed on the brake drum 9, brake drum 9 drives by forward and backward brake-shoe 1.6 under the effect of brake force Back-plate 11 is pressed the N direction shown in the accompanying drawing 2a around axle tube 12 and is rotated. Because reinforcement cover 10 Be fixed on the axle tube 12, just produce a tensile force f, this tensile force f is passed to connecting rod 4 by pull bar 2 With connecting rod 3, correspondingly rear, fore brake 6,1 are applied a power F1And F2, and F1＞F
2.Braking The thrust T that wheel cylinder 5 produces is more big, and the brake force of wheel drag is more big; And the braking of wheel drag Power is more big, F and F1、F
2More big, F1、F
2More big, the braking moment M that forward and backward brake-shoe produces more Greatly; Thereby played the effect of a reinforcement. When the need brake off, just can reduce pushing away of wheel cylinder Power T until return spring 7 overcomes power T and F, makes brake-shoe separate with brake drum, returns to accompanying drawing Position shown in 1, but just brake off. In like manner reversing braking (shown in the accompanying drawing 2b) also is like this.
This invention is in braking procedure, if wheel skids on the ground, just braking force reduces accordingly, the F that just exerts all one's strength reduces, correspondingly F
1, F
2The power that is applied on the brake shoe brake cheek just reduces, thereby braking moment M is reduced, and has played the effect of anti-lock to a certain extent.
This invention can also make the power that is applied to the braking trailing shoe help the gesture hoof greater than braking.Prior art is at glancing impact, the direction of its friction force towards the brake shoe brake cheek of rest pin for helping the gesture hoof, and dorsad rest pin be trailing shoe.Help braking force that the gesture hoof produced greater than the braking force that trailing shoe produced, this invention can remedy this defective.F when driving
1＞F
2, reversing F
2＞F
1, can more effectively bring into play the effect of brake shoe brake cheek, and make the brake shoe brake cheek wearing and tearing more even.
The present invention compares with following prior art, has the following advantages.
1, the present invention can utilize the effect of reinforcement to increase the brake force of wheel drag.
2, the present invention can solve the deficiency that the Medium or severe type automobile adopts air-pressure brake, reduces power consumption, Energy savings.
3, the present invention is simple in structure, and brake shoe brake cheek is stressed rationally, and wearing and tearing evenly.
4, the present invention has the effect of certain braking anti-lock, helps traffic safety.
