Abstract
The utility model relates to a force boosted wheel brake, which is composed of front and back braking shoes, a braking drum, a braking bottom plate, a draw rod, a connecting rod, a return spring, etc. The force boosted wheel brake is characterized in that the braking shoes are fixed on the braking bottom plate via supporting pins, the braking bottom plate is loosely sheathed with a semi-axis sleeve pipe, and the braking bottom plate is axially positioned by a positioning shaft shoulder and a force boosted sleeve which are arranged on the semi-axis sleeve pipe. The utility model can efficiently enlarge the braking force of a vehicle. Therefore, the braking force of a hydraulic braking system is caused to satisfy requirements of a medium-size vehicle and a heavy-size vehicle. The insufficiency that the medium-size vehicle and the heavy-size vehicle adopt pneumatic braking is solved. The power consumption is reduced, and the energy is saved. The force boosted wheel brake has simple structure. The stress to the braking shoes is reasonable, and the brake shoes are worn out uniformly. The braking shoes have definite braking and anti-blocking functions, and the braking shoes are beneficial to safe driving.
Description
The utility model relates to a kind of fluid pressure type car side brake, belongs 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 utility model provides 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 utility model can be realized 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.
Constructional drawing and schematic diagram below in conjunction with augmented wheel brake are described in further detail the utility model.
Accompanying drawing 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 hubs 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.
Accompanying drawing 2 is schematic diagrams of augmented wheel brake reinforcement
When the running car glancing impact, the pulling force P that the thrust T that brake wheel cylinder 5 produces overcomes pull back spring 7 is pressed on the brake wheel 9, and brake wheel 9 drives back-plate 11 by forward and backward brake shoe brake cheek 1.6 and presses the N direction rotation shown in the accompanying drawing 2a around axle tube 12 under the effect of braking force.Because reinforcement cover 10 is fixed on the axle tube 12, just produces a tensile force f, this tensile force f is passed to connecting rod 4 and connecting rod 3 by pull bar 2, correspondingly back, fore brake 6,1 is applied a power F

2Big more, the braking moment M that forward and backward brake shoe brake cheek produces is big more; Thereby played the effect of a reinforcement.When the need brake off, just can reduce the thrust T of brake wheel cylinder, overcome power T and F until pull back spring 7, brake shoe brake cheek is separated with brake wheel, return to the position shown in the accompanying drawing 1, but just brake off.In like manner reversing braking (shown in the accompanying drawing 2b) also is like this.
This utility model 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 utility model 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, 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 utility model is compared with following prior art, has the following advantages.
1, the utility model can utilize the effect of reinforcement to increase the braking force of car side brake.
2, during the utility model can solve, heavy motor vehicle adopts the deficiency of compression air brake, reduces consumption of power, energy savings.
3, the utility model is simple in structure, and brake shoe brake cheek is stressed rationally, and wearing and tearing evenly.
4, the utlity model has the effect of certain braking anti-lock, help traffic safety.
