[0066] The front independent suspension system 27 includes a coil spring 1, a torsion bar spring 2, a coil spring mounting bracket 3, a torsion bar spring mounting bracket 4, a steering knuckle bracket 5, a steering knuckle 6, an upper swing arm 7 and a lower swing arm 8, and The steering knuckle bracket 5 is connecte...

Embodiment 2

[0068] Basic content is the same as embodiment 1, the difference is:

[0069] The upper left forearm foot 71, the upper left rear arm foot 72, the lower left forearm foot 81, and the lower left rear arm foot 82 are embedded with a corresponding first rubber bushing 74, a second rubber bushing 75, The third rubber bushing 84, the fourth rubber bushing 85, the axes of the first rubber bushing 74 and the second rubber bushing 75 are coaxial, the third rubber bushing 84, the fourth rubber bushing The axis line of 85 is coaxial. The axis line of the torsion bar spring 2 is parallel to the longitudinal plane of the vehicle frame 13, and the torsion bar spring 2 is located at the front end of the wheel; the shock absorber assembly 10 is located at the front end of the symmetrical center plane of the wheel. The distance between the axis of rotation of the upper swing arm 7 is less than or equal to the distance of the axis of rotation of the lower swing arm 8 , and the upper swing arm...

Embodiment 3

[0071] Basic content is the same as embodiment 1, the difference is:

[0072] The steering knuckle bracket 5 includes a bottom tray 55, a hollow cylinder 54 and an L-shaped bracket body 51. The bracket body 51 includes a bottom bracket arm 52 and a side bracket arm 53 connected to each other, and the inner end of the bottom bracket arm 52 is connected to the bottom tray. The bottom of 55 is connected, and the outer end of bottom support arm 52 is connected with the bottom of side support arm 53, and the top of side support arm 53 is hinged with upper right arm foot 73 by eccentric pin 9, and the outer end of side support arm 53 The position at the junction of the proximal support arm 53 and the upper right arm pin 73 on the side is connected with the outer wall of the hollow tube 54, and the inner wall of the hollow tube 54 is connected with the steering knuckle 6 through the steering kingpin 61, and the side bracket arm The bottom end of 53 is hinged with the lower arm seat 8...

Abstract

The invention relates to an independent suspension front axle assembly for a commercial vehicle. The assembly comprises a front support assembly, a rear support assembly and two front independent suspension systems, wherein the front support assembly and the rear support assembly are arranged along the central axis of a frame in a front-back mode, and the two front independent suspension systems are arranged along the central axis of the frame in a bilaterally symmetrical mode; each front independent suspension system comprises a spiral spring, a torsion bar spring, a spiral spring mounting support, a torsion bar spring mounting support, a steering knuckle support, a steering knuckle, an upper swing arm and a lower swing arm, wherein the upper swing arm and the lower swing arm are connected with the front support assembly and the rear support assembly through four types of connecting bosses, and the front support assembly and the rear support assembly are each of a U-type structure composed of the left section, the middle section and the right section. Accordingly, the large bearing requirement can be met, the reliability is high, the stiffness is large, the guide effect is good, the occupied space is small, the cost is low, and the handling stability and driving smoothness of the whole vehicle are improved.

Description

technical field [0001] The invention relates to a vehicle front axle assembly, which is applied in the field of single front axle structure of commercial vehicles, in particular to an independent suspension front axle assembly for commercial vehicles, which is specifically suitable for improving the strength and Reliability, vehicle handling stability and ride comfort. Background technique [0002] At present, the front axle of trucks generally adopts leaf spring non-independent suspension, which has the advantages of simple structure and low cost. As a result, the handling stability and smoothness of the vehicle are poor. In addition, the large axle load of the truck itself and the limited layout space also limit the introduction and application of other types of suspensions, such as air suspensions and independent suspensions. [0003] The publication number is CN106394154A, and the invention patent application published on February 15, 2017 discloses a commercial vehicle...
