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

A kind of front suspension assembly
Technical field
The present invention relates to a kind of front suspension assembly that can be widely applied to the middle-size and small-size high-end multi-functional commercial vehicle/comm..vehicle of 14T~1.8T and high-end light card, microcaloire vehicle.
Background technology
Be suspended in when car body weight supported, buffering, absorb the wheel up-down vibration that road shocks etc. causes, prevent that vibration from directly reaching car body.Thereby improve driver and crew's comfort, protection goods, reduction car body dynamic stress partly, actv. reduces the unbalancing value in the wheel movement, thereby suppresses the vibration of wheel, improves riding stability.The tradition independent suspension structure is complicated, cost is high, keep in repair and transport inconvenience, and the space hold of existing double wishbone suspension is big, directly has influence on the layout of driving engine and steering swivel system.
Summary of the invention
The object of the invention is exactly big in order to overcome the space hold that has suspension now, directly has influence on the defective of the layout of driving engine and steering swivel system, and a kind of front suspension assembly is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of front suspension assembly; Comprise subframe, coil spring assembly, bumper, bottom arm assembly; The subframe both sides are connected with left and right bottom arm assembly respectively; It is characterized in that: the both sides of subframe have respectively a spring perch be positioned at down swing arm above, inlay a coil spring assembly in each spring perch, each coil spring assembly is connected with cooresponding bottom arm assembly; On each bottom arm assembly outside, be provided with a steering swivel, a bumper is installed on each steering swivel.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Also be provided with a lateral connecting rod on the subframe, the two ends of lateral connecting rod are connected with left and right swing arm down respectively.
Tie bolt, nut were connected with subframe after swing arm was passed through one under each, simultaneously, also were connected with subframe through preceding tie bolt, a nut.
On the fastening end of preceding tie bolt, be provided with a taper pad.
The invention has the beneficial effects as follows that coil spring and bumper are arranged apart, spring arrangement is below subframe, and bumper is arranged in the structure of subframe side, has reduced taking of front overhang space, a lot of spaces of staying for the layout of driving engine; Spring and bumper be work separately, avoids mutual interference, has reasonably brought into play effect separately, has improved the stability of car load, ride comfort; Lateral connecting rod increases the roll rate of car load, reduces vehicle and crosses body roll curved or that concavo-convex road surface causes, increases stability and traveling comfort; The taper pad can prevent down the swing arm horizontal looseness; And the commonality of this suspension is high, applies to simultaneously on high-end light card, the microcaloire car.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
