Description

An automobile brake pipeline system

technical field

The utility model relates to the technical field of automobile control pipelines, in particular to an automobile brake pipeline system.

Background technique

Automobile service brake is an important part of the automobile. Its function is to slow down and stop the moving automobile and keep the speed of the automobile running downhill stable. It is the most important safety guarantee system for automobiles. Especially for coach cars, when students drive a coach car to practice driving, due to their low driving skills, they tend to panic when encountering complex road conditions, and there are safety hazards in the driving process, so they need to be accompanied by the coach to practice with the car, and they need to be in the co-pilot position Set the auxiliary brake device. At present, the front and rear wheel brake devices of the main and auxiliary brake devices used in coach cars share an air storage tank, which is mostly mechanically controlled, that is, the auxiliary brake pedal is connected to the main brake pedal of the car through a rod or a cable. Connected, the passenger in the co-pilot seat manipulates the sub-brake pedal to control the main brake pedal to work through a rod or a cable. This type of structure is relatively complicated, and what is more serious is that once the air reservoir is damaged and leaks, the front and rear wheels cannot be braked.

In order to solve the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide a pipeline system capable of controlling the start-up brake in the passenger cab.

The inventive idea of the utility model is: install a brake pedal and a brake master valve at the co-pilot position, install double-way one-way valves on the brake circuits of the front and rear axles of the chassis, and realize it through two independent front and rear axle air storage cylinders. Both the main cab and the co-cab can control the braking pipeline system.

An automobile brake pipeline system, including a main brake pipe composed of a front axle air storage tank, a main main brake valve, a front axle brake air chamber, a rear axle air storage tank, a relay valve and a rear axle brake air chamber It also includes auxiliary brake main valve, front two-way one-way valve and rear two-way one-way valve, the air inlet of the upper chamber of the auxiliary brake main valve is connected with the air outlet of the rear axle air tank through the air pipe , the air outlet of the upper chamber of the auxiliary brake master valve is connected to an air inlet of the rear two-way check valve through a gas pipe, and the air inlet of the lower chamber of the auxiliary brake master valve is connected to the front air inlet through a gas pipe. The air outlet of the bridge air storage tank is connected, the air outlet of the lower chamber of the auxiliary brake master valve is connected with an air inlet of the front two-way one-way valve through the air pipe, and the air outlet of the front two-way one-way valve is connected with the The front axle brake air chamber is connected, the air outlet of the rear two-way one-way valve is connected with the air inlet of the relay valve through the air pipe, and the air outlet of the relay valve is connected with the rear axle brake chamber. Gas chamber connection.

The air inlet of the upper chamber of the main brake master valve is connected to the air outlet of the rear axle air storage tank through a gas pipe, and the air outlet of the upper chamber of the master brake master valve is connected to the other of the rear two-way one-way valve. A gas inlet connection.

The air inlet of the lower chamber of the main brake master valve is connected with the air outlet of the front axle air reservoir through a trachea, and the air outlet of the lower chamber of the main brake master valve is connected with the other of the front two-way one-way valve. Inlet connection.

Through the test, the beneficial effect of the utility model is: the volume of the two newly added two-way one-way valves is small, and can be arranged arbitrarily, without affecting the arrangement scheme of other parts of the original car, and it solves the problem that the auxiliary brake pedal passes through the rod. Or the complex structure that the pull wire is connected with the main brake pedal of the car, overcomes the disadvantages of the passenger seat manipulating the auxiliary brake pedal to control the main brake pedal to work through rods or pull wires, using two independent air storage tanks, effectively Increase the braking safety performance of the coach car to ensure the driving safety of the vehicle.

detailed description

In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

Example 1

Referring to Fig. 1, the utility model is: an automobile brake pipeline system, comprising a front axle air reservoir 1, a main brake master valve 2, a front axle brake chamber 3, a rear axle air reservoir 4, a relay valve 5 and the main brake pipeline composed of the rear axle brake air chamber 6, also includes the auxiliary brake master valve 7, the front two-way check valve 8 and the rear two-way check valve 9, the upper part of the auxiliary brake master valve 7 The air inlet of the cavity is connected with the air outlet of the rear axle air storage tank 4 through the air pipe, the air outlet of the upper chamber of the auxiliary brake master valve 7 is connected with an air inlet of the rear two-way one-way valve 9 through the air pipe, and the auxiliary brake master valve The air inlet of the lower chamber of 7 is connected with the air outlet of the front axle air reservoir 1 through the air pipe, the air outlet of the lower chamber of the auxiliary brake master valve 7 is connected with an air inlet of the front two-way one-way valve 8 through the air pipe, and the front two-way The air outlet of the one-way check valve 8 is connected with the brake air chamber 3 of the front axle, the air outlet of the rear two-way one-way valve 9 is connected with the air inlet of the relay valve 5 through the air pipe, and the air outlet of the relay valve 5 is connected with the rear Axle brake chamber 6 is connected. The air inlet of the upper chamber of the main brake main valve 2 is connected with the air outlet of the rear axle air storage tank 4 through the air pipe, and the air outlet of the upper chamber of the main brake main valve 2 is connected with the other air inlet of the rear two-way one-way valve 9 connect. The air inlet of the main brake main valve 2 lower chamber is connected with the air outlet of the front axle air reservoir 1 through the air pipe, and the lower chamber air outlet of the main brake main valve 2 is connected with the other air inlet of the front two-way one-way valve 8 .

The specific implementation is divided into four situations. Neither the main brake pedal nor the auxiliary brake pedal is operated. At this time, the vehicle does not brake, and the coach car can run normally; when the main brake pedal is stepped on, the auxiliary brake pedal is not operated, and the vehicle brakes normally. The coach vehicle can run safely; the main brake pedal is not operated, and the auxiliary brake pedal is stepped on, and the coach vehicle can brake normally and drive safely; the main and auxiliary brake pedals are stepped on at the same time, and the air source is respectively connected to the main and auxiliary brake pedals. The two air inlets of the two-way one-way valve, and the characteristic of the two-way one-way valve is that the air pressure of the two air inlets is dominant, so it can guarantee the output air pressure of the two-way one-way valve, that is, the brake air chamber The input air pressure is the larger one, which avoids the situation of insufficient braking. Through the above analysis, the braking safety performance of the coach vehicle can be increased more effectively and the driving safety of the vehicle can be guaranteed.

The undescribed technical features of the utility model can be realized by or adopting the prior art, and will not be repeated here. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or replacements made by ordinary skilled persons within the essential scope of the present invention shall also belong to the present invention.
