Embodiment Construction

[0015] Example figure 1 As shown in the control schematic diagram of the lifting control system of the three-axis passenger car servo bridge, it at least includes an air storage tank 4 and an air bag 5. One output end of the air storage tank 4 is connected to the air bag 5 through the lifting height regulating valve 1, and the other side of the air storage tank 4 One output end is connected to the lifting height regulating valve 1 through the two-position three-way solenoid valve 3 controlled by the rocker switch 2 , and is connected to the air bag 5 by the lifting height regulating valve 1 .

[0016] The lifting height regulating valve 1 is fixed at the traveling bridge of the whole vehicle, including the regulating valve air inlet 6, the regulating valve air outlet 7, the regulating valve control port 8 and the regulating valve exhaust port 9, wherein the regulating valve air inlet 6 is connected to the storage The air cylinder 4 is connected, the air outlet 7 of the regulat...

Abstract

The invention relates to the field of bus servo bridges, in particular to a three shaft bus servo bridge lifting control system. The three shaft bus servo bridge lifting control system at least comprises a gas storage cylinder and a gas bag. The Three shaft bus servo bridge lifting control system is characterized in that an output terminal of the gas storage cylinder is connected with the gas bag through a lifting height adjusting valve, and the other output terminal of the gas storage cylinder is connected with the lifting height adjusting valve through a two-position three-way lifting height adjusting valve controlled by a rocker switch and is connected with the gas bag through the lifting height adjusting valve. Due to the fact that a driver controls the rocker switch, air filling and air exhausting of the gas bag are achieved, the effect of lifting the servo bridge gas bag is achieved, the center of the servo bridge is lowered during loading a car and unloading the car, loading is reduced, and abnormal wear to tires is reduced.

Description

technical field [0001] The invention relates to the field of passenger car follower bridges, in particular to a lifting control system for a three-axis passenger car follower bridge. Background technique [0002] With the continuous development of expressway construction, three-axle buses, as a part of modern intercity passenger transport, have attracted more and more attention. In recent years, with the continuous increase of inter-city communication and the increase of modern traffic, people have more and more diversified choices for travel. People not only require its safety, but also the comfort of passengers. The three-axle bus is just a new type of transportation that integrates safety and comfort, and more and more services are used for long-distance passenger transportation. Since the steering of the three-axle passenger car is mainly realized by ground friction, the early wear and tear of the tires is relatively serious. Contents of the invention [0003] The ob...
