Embodiment Construction

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0018] As shown in the figure, the present invention provides a single-point suspension with constant-section springs, including a constant-section leaf spring assembly 4, a first bolt clamp 1, a second bolt clamp 2 and a third bolt clamp 3;

[0019] The first bolt clamp and the second bolt clamp are respectively arranged at both ends of the equal-section leaf spring assembly for fixed connection with the axles at both ends; the third bolt clamp is arranged in the middle of the equal-section leaf spring assembly for Fixed connection with the central axis.

[0020] The leaf spring assembly is nine leaf springs of equal section.

[0021] The leaf spring assembly includ...

Abstract

The invention discloses a single-point suspension of uniform-cross section springs. The single-point suspension of the uniform-cross section springs comprises a uniform-cross section leaf spring assembly, a first bolt clamp, a second bolt clamp and a third bolt clamp. The first bolt clamp and the second bolt clamp are arranged at the two ends of the leaf spring assembly and used for being fixedly connected with axles at the two ends; and the third bolt clamp is arranged in the middle of the leaf spring assembly and used for being fixedly connected with a center shaft. The suspension of 17 leaf springs is changed into the single-point suspension of 9 uniform-cross section springs, the material specification is unified, so that the problem that running stability is affected by the fact that the total thickness of the leaf springs is too large as too many leaf springs are arranged and thus the height of center of gravity of the vehicle is too high is solved, and the weight of the leaf springs is decreased under the premises of guaranteeing the reliability and not shortening the life of the leaf springs (i.e. not increasing the design stress). The material saving effect is obvious, and the fuel consumption is favorably decreased.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a spring single-point suspension with equal section. Background technique [0002] At present, the single-point suspension of automobiles adopts leaf spring suspension, and the design load is 32 tons. Usually, 17 leaf springs are used for suspension. This kind of spring suspension transmits torque and eases impact. However, due to the large number of leaf springs, the total thickness of the 17 multi-leaf springs is too large, and the material waste is serious. After the vehicle is arranged, the height of the center of gravity is too high, which affects the driving stability; increases fuel consumption; and the material specifications are 3 types, The manufacturing process is more troublesome. [0003] Therefore, there is a need for a spring suspension with a small plate spring assembly thickness and stable driving. Contents of the invention [0004] In view of this, the technical pr...
