Vehicle balance suspension assembly structure

Abstract

The invention discloses a vehicle balance suspension assembly structure. A vehicle frame is used as a carrying body of a suspension system; the two ends of a steel plate spring are fixed on the upperend of a vehicle axle through a bridge passing end assembly; a balance shaft up-mounted structure is used; the steel plate spring is arranged at the lower end of a balance shaft case; under the condition that the height distance between the vehicle axle and the vehicle frame, the dimension and the weight of the balance shaft support seat can reach the optimum state; the whole equipment weight is reduced; meanwhile, during the load bearing, the weight is transmitted to the balancing shaft case by the vehicle frame, and is then transmitted to the steel plate spring and the vehicle axle; the fixed connection stress condition between the balance shaft case and the steel plate spring is reduced; the influence by the load bearing weight is avoided; the reliability is greatly improved; the service life is prolonged. The device uses the shaft end assembly of the balance shaft to rotationally connect the steel plate spring and the vehicle frame; the self adaptation capability of the conventional balance suspension to the uneven pavement is realized; the relative rotation height between the two vehicle axles is increased; the vehicle balance suspension assembly structure can adapt to complicated off-roads; the structure is simple; the weight is light; the universalization degree is high.

Description

technical field [0001] The invention relates to a leaf spring balance suspension assembly, in particular to a vehicle balance suspension assembly structure. Background technique [0002] At present, the suspension of trailers mostly adopts the leaf spring type with high stiffness and small dynamic deflection, which is mainly used for material transportation on good road surfaces, and it is difficult to meet the suspension performance requirements of off-road roads. And the existing leaf spring balance suspension assembly such as Figure 5 As shown in the schematic diagram of the traditional balance suspension, it is mainly composed of balance shaft assembly 1, leaf spring 2, lower thrust rod 3, axle 4, upper thrust rod 5, frame 6 and U-shaped bolt 7, and the leaf spring 2 passes through the U-shaped The bolt 7 is installed on the balance shaft assembly 1, and its two sides are matched with the slide plate seat of the axle 4 respectively, without longitudinal limit. The axle ...

Problems solved by technology

[0003] Due to the existence of the steering device, there is a certain height difference between the upper and lower frames of the shaft-steering drawbar trailer, and the front and rear suspensions are installed on the lower frame and the upper frame respectively. For a three-axle off-road trailer, if the rear The suspension directly uses the balance suspension of the prior art, which will cause the size and weight of the transition piece between the suspension and the vehicle frame to be relatively large, which will affect the performance of the vehicle, and the arrangement of the thrust rod mechanism will be very difficult, which is very difficult for existing vehicles. The structure of the bridge and the frame has been greatly changed, and the versatility is poor
