The utility model adopts technique scheme, controlling gas port place installation stop lamp switch device, at valve body control gas port, place has set up tightening seal washer, has improved the reliability of product, fault rate is reduced to 0.6% by 4.2%, for the assembling in enormous quantities of various vehicle lays the foundation.
Brief description of the drawings
Below the mark in accompanying drawing content, figure is briefly described:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Being labeled as in figure:
1, stretcher assembly, 2, piston, 3, valve body, 4, lower valve assembly, 5, brake lamp wire harness switch.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
Structure of the present utility model as shown in Figure 2, for a kind of braking system of diesel engine of commercial vehicle list chamber Piston Pneumatic Brake Valve, comprise stretcher assembly 1, piston 2, valve body 3, lower valve assembly 4, described air brake valve is by admission port and air extractor duct, be threaded with described brake system pipeline respectively, realize gas and carry.
In order to solve the problem of prior art existence and to overcome its defect, realize the goal of the invention of the handling and reliability that improves product, the technical scheme that the utility model is taked is:
As shown in Figure 2, braking system of diesel engine of commercial vehicle list of the present utility model chamber Piston Pneumatic Brake Valve is provided with brake lamp wire harness switch 5 on described valve body 3, and described brake lamp wire harness switch 5 is connected with the brake lamp circuit of described commercial vehicle/comm..vehicle.
In order to improve the reliability of product, the utility model carries out Transform Type design and update to the structure of existing product, improves performance, is controlling gas port place installation stop lamp switch device, thereby improves the performance of product.The utility model adopts technique scheme, and air brake valve has increased stop lamp switch device; Set up tightening seal washer and brake lamp band wire harness switch at valve body control gas port place, improved the performance of product.
On described lower valve assembly 4 and the valve port contact surface of valve body 3, tightening seal washer is set.
Described lower valve assembly 4 adopts and contacts hermetically-sealed construction with the valve port of valve body 3.
Principle of work of the present utility model and dynamic position relation:
The epitrochoidal chamber being made up of a piston, by the variation of brake-pedal travel, when automobile and trailer braking protection valve, can make air pressure in pipeline with the variation that is in proportion of control effort, only control a loop; And when working as service brake or travelling, brake lamp band wire harness switch will be controlled the bright of brake lamp or go out.When to the air inlet of air brake valve admission port, the leftover bits and pieces pedal assembly 1 that tramps with one's feet, piston 2 is opened lower valve assembly 4, and with its sealing, and brake lamp band wire harness switch 5 connects and opens, brake lamp is bright.
After above-mentioned improvement, new construction air brake valve obviously improves compared with original structure workability and reliability, and fault rate is reduced to 0.6% by 4.2%.The utility model has increased new product structure, has improved the performance of product, has reduced fault rate, for the assembling in enormous quantities of various vehicle lays the foundation.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
