Abstract
The utility model provides a pneumatic brake system for improving the safety of an air chamber, which comprises a compressor, an air reservoir, a front brake chamber, a rear brake chamber, a relay valve, a hand brake valve, a foot brake valve and a bi-pass non-return valve that are connected via an air passage, and is characterized in that a brake lamp sensor (16) is mounted at an air inlet of the rear brake chamber. The utility model can realize more accurate brake signal response, shorten the response time of a brake signal lamp and the brake action, and realize synchronization of the brake action and the lighting of the brake lamp, thereby improving the synchronization and accuracy of the signal lamp and the brake action, and improving the safety of the braking system.
Description
Technical field
The utility model relates to a kind of Pneumatic braking system that improves the air chamber safety, particularly is suitable for the used Pneumatic braking system of mining car, belongs to the vehicle brake technology field.
Background technology
At present, in the vehicle of Pneumatic braking system, general braking sensor all is contained on the foot brake valve, and at the driving glancing impact, after the brake pedal action, speed-slackening signal sends simultaneously, passes to stop, tail and number plate light.Simultaneously, this air-flow also is used for controlling back travelling gantry frame relay valve, realizes braking maneuver.But the foot brake valve is in operator's compartment, with back travelling gantry frame air chamber one segment distance is arranged, since the action begin to the process of end of braking arranged one period reaction time, when wherein a certain pipeline breaks suddenly, braking maneuver can lose efficacy, but stop, tail and number plate light still can Chang Liang, gives the speed-slackening signal of a mistake of vehicle at rear, has traffic hidden danger.The end that is issued to braking maneuver of this speed-slackening signal simultaneously has the regular hour poor, and the signal synchronism is relatively poor.
Summary of the invention
The purpose of this utility model is in order to improve the accuracy that speed-slackening signal transmits, to shorten the reaction time simultaneously, strengthens the safety of brake system and a kind of Pneumatic braking system that improves the air chamber safety of design-calculated.
The technical solution of the utility model: the Pneumatic braking system of raising air chamber of the present utility model safety comprises that it is characterized in that: the brake lamp sensor is installed in the admission port of back compressed air brake cylinder by gas circuit bonded assembly compressor, air receiver, preceding compressed air brake cylinder, back compressed air brake cylinder, relay valve, hand brake valve, foot brake valve, bilateral check valve.
Advantage of the present utility model: this novel practical can be realized speed-slackening signal reaction more accurately, shorten the reaction time of stop, tail and number plate light and braking maneuver, realize that braking maneuver and brake lamp are bright synchronously, so just can improve the synchronism and the accuracy of signal lamp and braking maneuver, the safety that has improved brake system.

The specific embodiment
Fig. 1 is a brake system schematic diagram of the present utility model: Pneumatic braking system of the present utility model comprises by gas circuit bonded assembly compressor 1; complex dryer 2; regeneration air receiver 3 four-loop protection valves 4; preceding braking during standstill air receiver 5; preceding service brake air receiver 6; back braking during standstill air receiver 7; back service brake air receiver 8; back compressed air brake cylinder 11a and 11b; preceding compressed air brake cylinder 12a and 12b; preceding compressed air brake cylinder and back compressed air brake cylinder and foot brake valve 14 bonded assembly relay valve 9a and 9b; preceding compressed air brake cylinder and back compressed air brake cylinder and hand brake valve 13 bonded assembly differential type relay valve 10a and 10b; bilateral check valve 15; preceding braking electromagnetic valve 19a and back braking electromagnetic valve 19b; preceding Parking air receiver 5 and preceding braking air receiver 6; back Parking air receiver 7 and back braking air receiver 8, preceding braking electromagnetic valve 19a and back braking electromagnetic valve 19b.The 17th, crosspointer air-pressure gauge, the 18th, air pressure horn.Brake lamp sensor 16 is installed in the admission port A3 or the A4 of back compressed air brake cylinder.
Principle explanation: carry out glancing impact when the driver steps on foot brake pedal, foot brake valve 14 can conductings, and gas is to brake lamp sensor 16, the unlatching of the electric signal control brake lamp of brake lamp sensor; Simultaneously, when the gas of being come by foot brake valve 14 enters back axle air chamber 11a through back axle relay valve 9b, by brake lamp sensor 16 signal is passed to brake lamp simultaneously, realize that braking maneuver and brake lamp are bright synchronously, so just can improve the synchronism and the accuracy of signal lamp and braking maneuver.
Core of the present utility model is the admission port that the brake lamp sensor is installed in the back compressed air brake cylinder, realizes that braking maneuver and brake lamp are bright synchronously.Therefore, every brake lamp sensor is installed in the admission port of back compressed air brake cylinder, all belongs to protection domain of the present utility model.
