Embodiment 1

[0027] refer to Figure 1 to Figure 3 , this device is a double-shock-absorbing single-trailing-arm independent suspension installed on a low-speed vehicle. The low-speed vehicle mainly includes a vehicle body 7, wheels 28, axle housing 1 and support 3, and the support 3 is connected to the vehicle body 7 through bolts 4. Connection, axle housing 1 is connected with wheel 28. refer to figure 2 and image 3 , the device mainly includes a suspension trailing arm 8, a spring 2 and a shock absorber 5, the suspension trailing arm 8 is located in front of the wheel 28, and its height is below the wheel center of the wheel 28, and the suspension trailing arm 8 is welded to the axle housing 1 , and is hinged with the vehicle body 7 through the trailing arm pin 9 . refer to Figure 7 , The suspension trailing arm 8 adopts a bifurcated structure, and the material is a high-strength welded steel plate, and a box-shaped closed-section welded structure. The suspension trailing arm 8 ...

Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 is that the upper support 10 of the shock absorber is not installed on the support 3, the lower support 12 of the shock absorber is not installed on the axle housing 1, and the shock absorber 5 is directly connected through the shock absorber pin 11. Installed between the axle housing 1 and the support 3.

Abstract

The invention discloses a double-damping single trailing arm independent suspension and belongs to the field of a special low-speed vehicle. The device comprises a vehicle body, wheels, an axle housing, a support, a suspension trailing arm, a spring and a damper, wherein the support is connected with the vehicle body through a bolt; the axle housing is connected with a wheel; the suspension trailing arm is positioned in front of the wheel; the height of the suspension trailing arm is slightly below a wheel center of the wheel; the suspension trailing arm is fixed on the axle housing and is hinged with the vehicle body through a trailing arm pin shaft; the spring is arranged between the axle housing and the support; the damper is positioned at the rear of the wheel; and the damper is arranged between the axle housing and the support. The device can be successfully applied on the special low-speed vehicle. A double-damping system is adopted. The damping performance of the suspension is improved.

Description

technical field [0001] The invention belongs to the field of low-speed special vehicles, and in particular relates to a double-shock-absorbing single-trailing-arm independent suspension. Background technique [0002] Vehicle suspension can be divided into two categories: independent suspension and non-independent suspension according to the form of guiding mechanism. The main advantage of independent suspension is that it allows the wheels to have a large jumping space, and the spring can also be designed to be relatively soft, and the tires have good grounding performance. , ride comfort is good, but the structure is complicated and the cost is high. It is mainly used in cars, and also in some light passenger vehicles, trucks and off-road vehicles, as well as some high-end buses; independent suspensions mainly include single wishbone and single trailing arm Type, single inclined arm type, longitudinal arm torsion bar type, double wishbone type, multi-rod type, sliding colu...
