Embodiment Construction

[0045] The present invention provides a single-point suspension device. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] figure 2 It is a structural schematic diagram of a single-point suspension device described in a preferred embodiment of the present invention. Such as figure 2 As shown, a single-point suspension device of the present invention includes a first axle assembly 206 and a second axle assembly 203 for installing tires, and also includes a central axis platform 208 fixedly connected with the vehicle frame and a middle Shaft 205; several shear springs 202 arranged on both side plates of the central axis platform and fixed...

Abstract

A single-point suspension device comprises: a first axle assembly (206) and a second axle assembly (203) for tire installation; a central shaft platform (208) fixedly connected with a frame and a central shaft (205); a plurality of shear springs (202) arranged on two side plates of the central shaft platform (208) and fixedly connected with the central shaft; a plurality of variable-rigidity springs arranged on the lower side of a top plate of the central shaft platform (208) and fixedly connected with the central shaft (205); a first balancing beam structure (204) and a second balancing beam structure (207) which are connected with two ends of the central shaft (205). Two ends of the first balancing beam structure (204) are fixedly connected with the first axle assembly (206) and the second axle assembly (203) respectively, and two ends of the second balancing beam structure (207) are fixedly connected with the first axle assembly (206) and the second axle assembly (203) respectively. The damping effect of the single-point suspension device is improved, and the impact force acting on the central shaft bearing seat and the central shaft platform is buffered effectively, and the complicated manufacture process of board spring is avoided and the self-weight is reduced.

Description

technical field [0001] The invention relates to a suspension device, in particular to a single-point suspension device for the vehicle frame and tires of a trailer or a semi-trailer made of rubber springs. Background technique [0002] Existing single-point hitches for trailers and semi-trailers, such as figure 1 As shown, the leaf spring 101 is used as a buffer member, which is installed horizontally at both ends of the center shaft assembly, connecting the center shaft assembly and the axle assembly. The leaf spring is made by stacking multiple metal plates. [0003] However, the use of leaf springs as buffers has the following disadvantages: [0004] 1. The manufacturing process of the leaf spring is complicated, and the quality cannot be guaranteed. [0005] 2. The large volume and weight of the leaf spring make the single-point suspension itself bulky, which reduces the effective load capacity of the vehicle and increases fuel consumption. [0006] 3. When the vehicl...
