Description
Technical field
The utility model relates to a kind of compression air brake parking device in middle-size and small-size disc type trac. assembling.
Background technology
At present, on middle-size and small-size trac., generally use mechanical brake or adopt the hydraulic oil brake gear to carry out vehicle braked, mechanical braking device in use ubiquity the braking force deficiency, especially under the precipitous situation of mountain road, usually cause grave accidents such as car crash because of the braking force deficiency, adopting hydraulic oil usually to brake enters under the situation of air or obstruction because of the hydraulic oil inefficacy or in the brake pipeline, cause brake failure, therefore be badly in need of a kind of brake equipment that can change the said apparatus defective.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and the compression air brake parking device of effective, the safe and reliable disc type trac. of a kind of drag assembling is provided.
The master cylinder that the technical solution of the utility model is achieved in that the storage tank that comprises air compressor, be connected by pipeline and air compressor, be connected with storage tank, the brake cylinder that is connected with master cylinder, be installed in the safety valve on the storage tank, it is characterized in that: storage tank also is connected by pipeline and hand control valve (HCV), hand control valve (HCV) is connected by pipeline and brake cylinder again, the air-pressure gauge that is connected by pipeline and storage tank.
Between master cylinder and brake cylinder, be provided with rapid release valve.
Also be provided with rapid release valve between hand control valve (HCV) and the brake cylinder.
Between air compressor and storage tank, be provided with check valve.
Described brake cylinder is the braking wheel cylinder of dying, and the braking wheel cylinder of dying comprises service brake chamber and braking during standstill chamber, and master cylinder is connected with the service brake chamber of the braking wheel cylinder of dying, and hand control valve (HCV) is connected with the braking during standstill chamber of the braking wheel cylinder of dying.
Described air compressor is connected with driving engine.
The utlity model has safe and reliable, manual dexterity, good braking effect, advantage easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, embodiment 1: the storage tank 2 that the utility model comprises air compressor 1, be connected by pipeline and air compressor 1, the master cylinder 3 that is connected with storage tank 2, the brake cylinder 7 that is connected with master cylinder 3, be installed in the safety valve 4 on the storage tank 2, it is characterized in that: storage tank 2 also is connected by pipeline and hand control valve (HCV) 5, hand control valve (HCV) 5 is connected by pipeline and brake cylinder 7 again, the air-pressure gauge 6 that is connected by pipeline and storage tank 2.Master cylinder 3 is connected with braking control device, and the effort of people's pin is on braking control device, and control master cylinder 3 is worked.
As shown in Figure 1, embodiment 2: the utility model comprises air compressor 1, the storage tank 2 that is connected by pipeline and air compressor 1, the master cylinder 3 that is connected with storage tank 2, the brake cylinder 7 that is connected with master cylinder 3, be installed in the safety valve 4 on the storage tank 2, it is characterized in that: storage tank 2 also is connected by pipeline and hand control valve (HCV) 5, hand control valve (HCV) 5 is connected by pipeline and brake cylinder 7 again, the air-pressure gauge 6. that is connected by pipeline and storage tank 2 also is provided with rapid release valve 9. and is provided with check valve 10. described brake cylinders 7 is the braking wheel cylinder 7 of dying between air compressor 1 and storage tank 2 being provided with between master cylinder 3 and the brake cylinder 7 between rapid release valve 8. hand control valve (HCV)s 5 and the brake cylinder 7, the braking wheel cylinder 7 of dying comprises service brake chamber and braking during standstill chamber, master cylinder 3 is connected with the service brake chamber of the braking wheel cylinder 7 of dying, and hand control valve (HCV) 5 is connected with the braking during standstill chamber of the braking wheel cylinder 7 of dying. and described air compressor 1 and driving engine are with belt, chain or transmission shaft are connected.
The braking during standstill that hand control valve (HCV) can be used as control vehicle is the parking brake braking, also can be used as a kind of emergency brake, before vehicle start, the joystick of hand control valve (HCV) should be turned back and remove the braking during standstill position, make pressurized air charge into the braking during standstill chamber from the braking during standstill storage tank, the compressed energy-storage spring returns less than braking position the braking during standstill piston, and the piston of service brake is simultaneously also pulled back under the pull back spring effect.This moment, braking during standstill was removed, and vehicle can be started to walk, if but the air pressure of storage tank does not reach minimum guard value, then can not compression spring, thereby vehicle can not be started to walk.In air compressor, storage tank, pipeline, master cylinder, cause air pressure to reduce when break down in any position of safety valve or do not have air pressure, the braking wheel cylinder of dying also returns the generation braking effect, guarantees safety.
