Embodiment Construction

[0017] Such as figure 1 As shown, a front suspension assembly of the present invention includes a subframe 3, the subframe 3 can improve the connection stiffness of the whole bridge, the subframe 3 is connected to the vehicle through bolts, and the remaining parts can be connected to the subframe respectively. on frame 3.

[0018] The two sides of the subframe 3 are connected with the left and right lower swing arm assemblies 2 respectively, and each lower swing arm assembly 2 has two connection points with the subframe 3, such as Figure 5 As shown, at the first place, the lower swing arm assembly 2 has a first connecting arm 21 protruding laterally, and a connecting hole is formed on the first connecting arm 21, a rubber bush 15 is embedded in the connecting hole, and a A u-shaped connecting bracket has a pair of coaxial through holes on the connecting bracket, and the first connecting arm 21 can extend into the u-shaped connecting bracket, and is connected with the subfram...

Abstract

The invention relates to a front suspension assembly. The front suspension assembly comprises a secondary vehicle frame (3), coil spring assemblies (5), shock absorbers (1) and lower swinging arm assemblies (2), wherein the two sides of the secondary vehicle frame (3) are respectively connected with left and right lower swinging arm (2) assemblies in a matching way; the front suspension assembly is characterized in that: a spring seat (31) positioned above the lower swinging arm (2) is respectively arranged on the two sides of the secondary vehicle frame; a coil spring assembly (5) is embedded into each spring seat (31); each coil spring assembly (5) is connected with the corresponding lower swinging arm (2) assembly; a steering knuckle (9) is arranged outside each lower swinging arm assembly (2); and a shock absorber (1) is arranged on each steering knuckle (9). The front suspension assembly has the advantages that: by using the structure that the coil springs and the shock absorbers are arranged separately, namely the springs are arranged below the secondary vehicle frame and the shock absorbers are arranged on the side surfaces of the secondary vehicle frame, the space occupation of a front suspension is reduced, and enough space is reserved for the arrangement of an engine; and the springs and the shock absorbers work separately so as to avoid mutual interference, reasonably play respective roles, and improve the stability and the smoothness of an overall vehicle.

Description

technical field [0001] The invention relates to a front suspension assembly that can be widely applied to 14T-1.8T small and medium-sized high-end multifunctional commercial vehicles and high-end light trucks and micro trucks. Background technique [0002] While supporting the weight of the car body, the suspension buffers and absorbs the up and down vibration of the wheels caused by road impacts, etc., preventing the vibration from being directly transmitted to the car body. Thereby improving the comfort of the driver and passengers, protecting the goods, reducing the dynamic stress of the car body, effectively reducing the dynamic unbalance in the wheel movement, thereby suppressing the vibration of the wheel and improving the driving stability. The traditional independent suspension has complex structure, high cost, and inconvenient maintenance and transportation. The existing double-wishbone suspension takes up a lot of space, which directly affects the layout of the eng...
