Described Switch main body is threadeded with pipeline or gas receiver by air inlet.
Arranging diaphragm between described air inlet and contact ring assembly, described diaphragm contacts sealing with the valve port of Switch main body.
In order to realize the goal of the invention identical with technique scheme, this utility model additionally provides above-described automobile and the control method of engineering machinery Pneumatic braking system warning light switch, and its technical scheme is:
Described contact ring assembly contacts with contact disc assembly, and namely warning light is bright; Otherwise warning light goes out;
To braking light switch inlet charge, it is braked;
When the protection air pressure that air inlet air pressure requires higher than regulation, the elastic force of compression spring can be overcome time, contact disc assembly separates power-off with contact ring assembly, and namely warning light goes out, now without warning;
When the pressure of air inlet gas is decreased below protection air pressure that regulation requires from high pressure, can not overcome the elastic force of compression spring, contact disc assembly contacts energising with contact ring assembly, and namely warning light is bright, it is achieved undervoltage warning.
This utility model adopts technique scheme, by improving product structure, improves the performance of warning light, reduces fault rate, extend its use and receive the order, it is ensured that the warning function that brake system pressure is not enough, lays the foundation for the high-volume assembling of various vehicle.

Detailed description of the invention
Below against accompanying drawing, 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 that inventive concept of the present utility model, technical scheme are had more complete, accurate and deep understanding.
Structure of the present utility model as shown in Figure 2, for a kind of automobile and engineering machinery Pneumatic braking system warning light switch, including Switch main body 1, contact ring assembly 3, contact disc assembly 4 and compression spring 5, described compression spring 5 acts on described contact disc assembly 4; Described contact ring assembly 3 is provided with silver contact 6. This utility model is applied to automobile and engineering machinery Pneumatic braking system, is typically installed on the pneumatic circuit of gas receiver or brakes.
In order to solve prior art Problems existing and overcome its defect, it is achieved improving the goal of the invention in its serviceability and life-span, the technical scheme that this utility model is taked is:
As in figure 2 it is shown, automobile of the present utility model and engineering machinery Pneumatic braking system warning light switch, described silver contact 6 is fixed on described contact ring assembly 3 by riveted structure.
This utility model improves product structure, it is to avoid because of the major defect that silver contact is uneven or defect is easily caused pitting of contacts and causes, improve the serviceability of product, improve the security performance of car load, reduce fault rate, extend service life, lay the foundation for the high-volume assembling of various vehicle.
Described contact disc assembly 4 is towards the one side of contact ring assembly 3, for the plane of annular. Its static position relation is: contact ring assembly 3 contacts with contact disc assembly 4, and namely warning light is bright. Otherwise, then warning light goes out.
Improved project of the present utility model includes: cancelled by the silver solder on contact disc assembly 4; Change the silver soldering sheet on contact ring assembly 3 into riveted joint, it is to avoid rigid contact is insufficient, improves reliability and the safety of system.
Mounting connection structure of the present utility model: warning light switch is threadeded with pipeline or gas receiver by air inlet, realizes air pressure alarm. That is: described Switch main body 1 is threadeded with pipeline or gas receiver by air inlet 7.
Arranging diaphragm 2 between described air inlet 7 and contact ring assembly 3, described diaphragm 2 contacts sealing with the valve port of Switch main body 1.
Dynamic position relation of the present utility model:
System is to braking light switch air inlet 7 air inlet, and when air pressure can overcome compression spring 5, contact disc assembly 4 separates power-off with contact ring assembly 3, and namely warning light goes out;
When air pressure drops to, from high pressure, the elastic force that can not overcome compression spring 5, contact disc assembly 4 contacts incoming call with contact ring assembly 3, and namely warning light is bright.
Operation principle: when the protection air pressure that air inlet air pressure requires higher than regulation, contact disconnects, and namely lamp goes out; When the protection air pressure that air inlet air pressure requires lower than regulation, contacting, namely lamp is bright, it is achieved report to the police.
In order to realize the goal of the invention identical with technique scheme, this utility model additionally provides above-described automobile and the control method of engineering machinery Pneumatic braking system warning light switch, and its technical scheme is:
Described contact ring assembly 3 contacts with contact disc assembly 4, and namely warning light is bright; Otherwise warning light goes out;
To braking light switch air inlet 7 air inlet, it is braked;
When the protection air pressure that air inlet air pressure requires higher than regulation, the elastic force of compression spring 5 can be overcome time, contact disc assembly 4 separates power-off with contact ring assembly 3, and namely warning light goes out, now without warning;
When the pressure of air inlet gas is decreased below protection air pressure that regulation requires from high pressure, can not overcome the elastic force of compression spring 5, contact disc assembly 4 contacts energising with contact ring assembly 3, and namely warning light is bright, it is achieved undervoltage warning.
After above-mentioned improvement, new construction warning light switchs relatively original structure workability and reliability and significantly improves, and fault rate is reduced to 0.6% by 4.2%.
Above in conjunction with accompanying drawing, this utility model is exemplarily described; obvious this utility model implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model design carries out with technical scheme; or not improved design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
