[0002] The components of the air handling system of conventional new energy light trucks are dispersed in different positions of the chassis according to the layout of the battery pack and the power form. The layout is relatively scattered, mainly arranged on the inside of the frame, and the connecting pipes between the components of the air handling system are relatively messy; at the same time, the pipes must be dispersed with the cooling pipes, high-voltage wiring harnesses and low-voltage wiring harnesses, which makes the layout difficult and the neatness of the chassis poor; it is also necessary to arrange the components in different positions according to the needs of different models, which requires a lot of work and is difficult to unify; in addition, the components of the air handling system are arranged on the inside of the frame, which makes maintenance inconvenient.

[0003] An integrated vehicle brake air supply system (publication number CN217300849U) has now appeared, which integrates an electric air compressor, an air dryer, an air tank, and an air filter to improve production and assembly efficiency, facilitate the layout of connecting pipes between various components, simplify the direction of connecting pipes, improve the stability of the brake air supply system, and reduce the use of bracket accessories.

[0004] However, the existing integrated vehicle brake air supply system integrates the air cylinder with components such as the electric air compressor, which increases the distance between the air cylinder and the front and rear axle brake air chambers, increases the braking response time, and does not integrate a four-circuit protection valve. It is necessary to specially set up a pipeline connecting the four-circuit protection valve. At the same time, the four-circuit protection valve needs to be specially installed on the vehicle assembly line, affecting the assembly rhythm of the vehicle. In addition, its load-bearing bracket has a sharp-angle transition, which will cause stress concentration and pose a risk of failure. Utility Model Content

[0030] In this embodiment, the integration of the air reservoir is cancelled, so that when the whole vehicle is developed, the air reservoir can be arranged as needed near the front and rear axle brake air chambers, which is beneficial to improving the braking response speed; in addition, the four-circuit protection valve 8 is directly installed on the air dryer 7 through a pipe joint, and there is no need to specially set up a pipeline connecting the four-circuit protection valve 8, which facilitates the installation of the four-circuit protection valve 8, improves the loading efficiency, and reduces the air path transmission distance, which is beneficial to improving the performance of the system.

[0031] Specifically, the air circuit includes a first air intake hose 2, a high-temperature hose 4 and a second air intake hose 6. The main body of the mounting bracket 9 is L-shaped. The electric air compressor 3 is fixedly mounted on the mounting bracket 9 and is located in the middle position of the mounting bracket 9. A supporting portion is fixedly mounted on both sides of the mounting bracket 9. The air filter 1 is fixedly mounted on the supporting portion on one side of the mounting bracket 9.
