Embodiment 1

[0068] see Figure 1 to Figure 6, a commercial vehicle single front axle structure with independent suspension, including symmetrically arranged left independent suspension 1 and right independent suspension 2, said left independent suspension 1 is connected with right independent suspension 2 through vehicle frame 3 connection; the vehicle frame 3 includes symmetrically arranged left longitudinal beams 31 and right longitudinal beams 32, and the left longitudinal beams 31 are fixedly connected to the right longitudinal beams 32 through the front pocket beams 33 and the rear pocket beams 34 respectively; the left independent The suspension 1 includes a left connecting bracket 11, a first left leaf spring 12, a second left leaf spring 13, a third left leaf spring 14 and a fourth left leaf spring 15; one side of the left connecting bracket 11 is connected to the left steering knuckle 4, the other side of the left connecting bracket 11 is respectively connected with the first lef...

Embodiment 2

[0070] Embodiment 2 is basically the same as Embodiment 1, the difference is:

[0071] The first left leaf spring 12, the second left leaf spring 13, the third left leaf spring 14, the fourth left leaf spring 15, the first right leaf spring 22, the second right leaf spring 23, the third right leaf spring 24 It is equal to the included angle between the fourth right leaf spring 25 and the central axis of the vehicle frame 3 , and the included angle between the first left leaf spring 12 and the central axis of the vehicle frame 3 is 60 degrees.

Embodiment 3

[0073] Embodiment 3 is basically the same as Embodiment 2, the difference is:

[0074] Described left front plate spring fixed frame 16 comprises fixed plate 83, upper fixed seat 84 and lower fixed seat 85, and described fixed plate 83 is fixedly connected with upper fixed seat 84 and lower fixed seat 85 respectively, and described first left leaf spring 12 The upper fixing seat 84 is fixedly connected by bolts and U-shaped bolts respectively, and the third left leaf spring 14 is fixedly connected with the lower fixing seat 85 by positioning bolts and U-shaped bolts respectively; the left rear leaf spring fixing frame 17 is the left front The mirror image structure of leaf spring holder 16; The structure of described left front leaf spring holder 16 is identical with the structure of right rear leaf spring holder 27, and the structure of described right front leaf spring holder 26 is identical with left rear leaf spring holder 17; The lower end of the upper fixing seat 84 is p...

Abstract

A commercial vehicle single front axle structure with independent suspensions comprises the left independent suspension and the right independent suspension which are arranged symmetrically. The left independent suspension is connected with the right independent suspension through a vehicle frame. The vehicle frame comprises a left longitudinal beam and a right longitudinal beam which are symmetrically arranged. The left longitudinal beam is fixedly connected with the right longitudinal beam through a front pocket beam and a rear pocket beam. The independent suspensions are connected with the front pocket beam and the rear pocket beam through connection brackets and four plate springs correspondingly. The bottoms of the connection brackets are connected with the longitudinal beams through shock absorbers. A gear rack steering system is connected with steering knuckles. The commercial vehicle single front axle structure is reasonable, high in mechanical strength, good in bearing characteristic and conductive to improving the smoothness and operation stability of a whole vehicle.

Description

technical field [0001] The invention relates to a single front axle structure of a commercial vehicle, in particular to a single front axle structure of a commercial vehicle with an independent suspension, which is particularly suitable for improving the handling stability and driving comfort of a commercial vehicle. Background technique [0002] At present, the front axle of commercial vehicles generally adopts leaf spring non-independent suspension, and matches the trapezoidal steering mechanism. The leaf spring non-independent suspension has the advantages of simple structure and low cost. However, due to the mutual influence of the wheels on both sides, the large friction between the leaf spring sheets, the large unsprung mass, and the large steering error, the handling stability of the vehicle is peaceful. The compliance is poor. Independent suspension can overcome the above shortcomings, but there are few commercial vehicle independent suspension related designs or pa...
