[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 2 This embodiment discloses a rear suspension assembly for a commercial vehicle cab with a trailer valve, comprising a rear suspension crossbeam 1, two V-shaped connecting beams 2 fixedly mounted on the surface of the rear suspension crossbeam 1, rear suspension underpinning supports 3 fixedly mounted at both ends of the V-shaped connecting beams 2, two airbag shock absorber assemblies 4 and a lateral shock absorber assembly 5 fixedly mounted between the rear suspension crossbeam 1 and the V-shaped connecting beams 2, two connecting brackets 6 fixedly mounted on the surface of the V-shaped connecting beams 2, a trailer valve bracket 7 fixedly mounted on the surface of the connecting bracket 6, and a trailer cable assembly 8, an air brake spiral tube bracket 9, and a 24N type electrical connector socket assembly 10 provided on the trailer valve bracket 7.
[0017] The V-shaped connecting beam 2 is equipped with an air intake pipe bracket assembly 11 and a trailer valve assembly 12. The rear suspension crossbeam 1 is equipped with two hydraulic locking bolt assemblies 13. The hydraulic locking bolt assembly 13 is equipped with a micro switch 14. The rear suspension lower support 3 is made of aluminum alloy.
[0018] It should be noted that, in this embodiment, one of the hydraulic bolt assemblies 13 is equipped with a two-position vent valve.
[0019] The working principle of the above embodiments is as follows:
[0020] By integrating the trailer cable assembly 8, the air brake spiral tube bracket 9, and the 24N type electrical connector socket assembly 10 onto the trailer valve bracket 7, the space required for independent installation is reduced, and the overall layout is improved in terms of compactness and rationality. The trailer valve bracket 7 is connected to the V-shaped connecting beam 2 using the connecting bracket 6, which improves the installation efficiency of the trailer valve bracket 7. The centralized component layout simplifies the assembly process, shortens the assembly time, and reduces the complexity of the process.
