Abstract

The utility model discloses a speed slowing emergency controllable hydraulic brake device for an automobile. The speed slowing emergency controllable hydraulic brake device comprises a three-way valve and an external-contacting hydraulic brake, wherein the external-contacting hydraulic brake sequentially comprises brake shoes, a brake pad and a brake wheel hub from the exterior to the interior, the three-way valve is a manual valve or an electrical valve and is connected with a direction assistance oil pump, an oil tank and a hydraulic cylinder respectively through oil pipes, the direction assistance oil pump is connected with the oil tank through an oil pipe, a piston rod of the hydraulic cylinder is arranged at an opening of a pair of the brake shoes of the external-contacting hydraulic brake in a penetrating way, a return spring is arranged on the piston rod between the pair of the brake shoes in a penetrating way, and a hydraulic pressure gauge is arranged on the oil pipe between the three-way valve and the hydraulic cylinder. The speed slowing emergency controllable hydraulic brake device for the automobile is simple in structure, low in cost, independent and safe for braking and is firm, practical, stable and reliable.

Description

The emergent slowly controlled hydraulic brake equipment of automobile
Technical field
The utility model relates to the emergent slowly controlled hydraulic brake equipment of a kind of automobile.
Background technology
Retarder brakes such as known at present exhaust, exhaust valve, fluid power, current vortex, to having played the effect of slow braking in the running car, but weak point is: one of which, exhaust and air exhaust valve brake moment are less, and diminishing driving engine influences service life.Its two, fluid power and current vortex retarder brake complex structure, volume and quality are bigger, braking potential is poor during low speed, manufacturing cost is high.Its three, existing various retarder brakes are uncontrollable, do not have the function of emergency brake.
The utility model content
The utility model provides a kind of automobile emergent slowly controlled hydraulic brake equipment, and the function of existing slow controllable brake has the function of emergency brake again.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: the emergent slowly controlled hydraulic brake equipment of automobile; Comprise triple valve and hem type hydraulic brake, described hem type hydraulic brake ecto-entad comprises brake shoe brake cheek, brake plate, brake hub successively, and described triple valve is hand control valve (HCV) or electrically-controlled valve; Triple valve is connected with direction power-assisted oil pump, fuel tank, hydraulic actuating cylinder respectively through oil pipe; Direction power-assisted oil pump is connected with mailbox through oil pipe, and the piston rod of hydraulic actuating cylinder is located in upper shed place of a pair of brake shoe brake cheek of hem type hydraulic brake, is equipped with pull back spring on the piston rod between a pair of brake shoe brake cheek.
Oil pipe between described triple valve and the hydraulic actuating cylinder is provided with charging water gauge.
Described brake shoe brake cheek lower end is provided with permanent seat, and permanent seat is provided with set pin, and brake shoe brake cheek is installed on axletree or the vehicle frame through the effect of permanent seat and set pin.
Described brake hub is connected with automobile gearbox, retarder or transmission shaft.
The utility model is simple in structure, and is with low cost, brakes independent safety, and firm practicality is reliable and stable.The utility model reasonable in design; The loss of driving engine noenergy; Do not change, do not influence the brake structure of former car; The power that utilizes automobile self direction power-assisted oil pump to provide by the principle of hydraulic pressure hand control valve (HCV) or the reasonable modulated pressure cylinder of hydraulic buttery valve pressure, has solved heavy-duty truck and large and medium bus effectively and under particular surroundings and unforeseen circumstances, has gone and realize the needs of slow braking or emergency braking.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: as shown in Figure 1; The emergent slowly controlled hydraulic brake equipment of automobile; Comprise triple valve 2 and hem type hydraulic brake 1, described hem type hydraulic brake 1 ecto-entad comprises brake shoe brake cheek 12, brake plate 11, brake hub 10 successively, and described triple valve 1 is hand control valve (HCV) or electrically-controlled valve; Triple valve 1 is connected with direction power-assisted oil pump 5, fuel tank 6, hydraulic actuating cylinder 8 respectively through oil pipe 4; Direction power-assisted oil pump 5 is connected with mailbox 6 through oil pipe, and the piston rod of hydraulic actuating cylinder 8 is located in upper shed place of a pair of brake shoe brake cheek 12 of hem type hydraulic brake 1, is equipped with pull back spring 9 on the piston rod between a pair of brake shoe brake cheek 12.Oil pipe between triple valve 2 and the hydraulic actuating cylinder 8 is provided with charging water gauge 3.Brake shoe brake cheek 1 lower end is provided with permanent seat 13, and permanent seat 13 is provided with set pin 14, and brake shoe brake cheek 12 is installed on axletree or the vehicle frame through the effect of permanent seat 13 and set pin 14.Brake hub 10 is connected with automobile gearbox, retarder or transmission shaft.
In the running car; According to the needs of slow braking or emergency braking, promote the hydraulic pressure hand control valve (HCV) or open hydraulic buttery valve to braking position, cooperate the brake piston bar of charging water gauge 3 modulated pressure cylinders 8; Brake shoe brake cheek 12 is closed under the effect of hydraulic actuating cylinder 8, and automobile is effectively braked.During brake off, promote the hydraulic pressure hand control valve (HCV) or open hydraulic buttery valve to walking position, make charging water gauge 3 reduce to zero position, brake shoe brake cheek 12 separates under the effect of retracing spring 5.
