Abstract
A synchronous braking system for an automobile comprises an air pump, a four-loop protective valve and a double-cavity braking master pump and further comprises a first air storage cylinder, a second air storage cylinder, a third air storage cylinder and a fourth air storage cylinder. The four-loop protective valve is communicated with an air inlet end of the first air storage cylinder, an air inlet end of the second air storage cylinder, an air inlet end of the third air storage cylinder and an air inlet end of the fourth air storage cylinder, wherein the air storage cylinders are connected in parallel. An air outlet end of the first air storage cylinder, an air outlet end of the second air storage cylinder and an air outlet end of the third air storage cylinder are respectively communicated with a relay valve and a brake chamber in sequence. The air outlet end of the first air storage cylinder and the air outlet end of the second air storage cylinder are further respectively communicated with air inlet ends of the double-cavity braking master pump and the relay valves connected with the rear portions of the air storage cylinders are communicated with an air outlet end of the double-cavity braking master pump. The fourth air storage cylinder is an auxiliary air storage cylinder. Air is supplied to the middle relay valve and the rear relay valve of double rear axles through the corresponding air storage cylinders, so that the purpose that the middle brake chamber and the rear brake chamber are independently controlled by the middle relay valve and the rear relay valve respectively is achieved, the problem that due to the fact that a brake air source is insufficient, the double rear axles cannot be braked synchronously is solved, and the brake performance of the whole automobile is improved.
Description
Technical field
The utility model relates to a kind of brake system of car, especially a kind of synchronous braking system for automobile.
Background technology
At present, the quarry tipper driving cycle is abominable, and the road surface situation is ever-changing, the fully loaded quality of car load is large, and is high to the drag requirement, and mining dump truck rear-axle is two back axles on the market, two back axle braking gas sources are the air receiver of two series connection, and by the two back axle brakings of relay valve control.In use, because braking gas source is not enough, two back axles can occurs and brake nonsynchronous situation, even a root bridge can occur and brake the situation that another root bridge is not braked, affect the deceleration and stopping performance of car load.
Summary of the invention
The utility model proposes a kind of synchronous braking system for automobile, solved the problem that two back axles can not synchronous braking, improved the deceleration and stopping performance of car load.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of synchronous braking system for automobile, comprise air pump, four-loop protection valve and double chamber brake master cylinder, also comprise the first air receiver, the second air receiver, the 3rd air receiver and the 4th air receiver, the outlet side of the first air receiver has been connected front axle relay valve and propons compressed air brake cylinder successively, the outlet side of the second air receiver has been connected middle axle relay valve and jackshaft compressed air brake cylinder successively, the outlet side of the 3rd air receiver is connected the back axle compressed air brake cylinder, the 4th air receiver is auxiliary air receiver, wherein the outlet side of the first air receiver and the second air receiver is also connected with the inlet end of double chamber brake master cylinder respectively, it is characterized in that: also connect the rear axle relay valve that control back axle compressed air brake cylinder is arranged on the outlet side of described the 3rd air receiver, be the front relay valve of install in parallel, middle relay valve and rear relay valve are also connected with the outlet side of double chamber brake master cylinder respectively; The inlet end that is the first air receiver, the second air receiver, the 3rd air receiver and the 4th air receiver of install in parallel is all connected with the outlet side of four-loop protection valve.
Beneficial effect: the utility model is because of the relay valve that has increased the two back axles of braking and the air receiver that adopts install in parallel, make in two back axles in, rear relay valve carries out air feed by air receiver separately, reach, rear relay valve independently control in, the purpose of rear compressed air brake cylinder, avoided having improved the deceleration and stopping performance of car load because the braking gas source deficiency causes the problem that two back axles can not synchronous braking.
