Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing:
[0017] Such as figure 1 The passenger car brake pipeline protection system shown includes a main air source 1, which supplies air to the main brake air storage tank 2 and the hand brake air storage tank 3 respectively, and the main brake air storage tank 2 passes through the brake The master cylinder 4 is connected to the rear axle 6, and the hand brake air storage tank 3 is connected to the rear axle 6 through the hand brake valve 5. The air circuit between the main air source 1 and the hand brake air storage tank 3 is equipped with a The pressure solenoid valve 9 is disconnected, and the pressure solenoid valve 9 is connected with the main brake air reservoir 2 through the vehicle pressure gauge 10 . That is, the pressure in the main brake air reservoir 2 can be measured through the vehicle pressure 10, and the on-off of the pressure solenoid valve 9 is controlled by jud...

The invention relates to a passenger car braking pipeline protection system and method. The passenger car braking pipeline protection system comprises a main gas source used for supplying gas to a main braking gas storage barrel and a hand braking gas storage barrel; the main braking gas storage barrel is connected with a rear axle through a braking master pump, and the hand braking gas storage barrel is connected with the rear axle through a hand braking valve; and a gas pipeline between the main gas source and the hand braking gas storage barrel is provided with a pressure electromagnetic valve for controlling the gas pipeline to be opened and closed, and the pressure electromagnetic valve is connected with the main braking gas storage barrel through an overall-car pressure gage. According to the passenger car braking pipeline protection system and method, it can be known from the technical scheme that the gas pressure in the main braking gas storage barrel is collected through the overall-car pressure gage, on the basis of the comparison between the pressure in the main braking gas storage barrel and the braking pressure, whether the main gas source supplies the gas to the hand braking gas storage barrel or not is controlled through the pressure electromagnetic valve so that whether hand braking can be relieved or not can be controlled; when the pipeline gas pressure is not enough to provide service braking, hand braking of the system also cannot be relieved; and the braking failure problem after accident starting is solved, and a remarkable effect on improving the safety of an overall car is achieved.
Description
technical field [0001] The invention relates to the field of passenger cars, in particular to a brake pipeline protection system and method for passenger cars. Background technique [0002] With the development of society and the continuous progress of the passenger car industry, the safety requirements for passenger cars are also getting higher and higher. The bus brake system is mainly composed of double circuit pipeline air brake, hand brake, auxiliary brake and so on. In the case of insufficient air pressure in the traditional passenger car, the hand brake can still be released, but after the hand brake is released, the service brake does not work, the driver cannot step on the brake, and there will be a phenomenon of sliding on the slope, which poses a great safety hazard . Contents of the invention [0003] The purpose of the present invention is to provide a passenger car brake pipeline protection system. When the pipeline air pressure is not enough to provide the...
