Problems solved by technology
Existing leaf springs are composed of a number of spring sheets with different lengths. Due to the direct contact between the reed sheets, each steel sheet will move up and down when the vehicle is running, resulting in friction, and this friction will interact to produce noise, coupled with the different degrees of deformation of different steel plates, resulting in problems such as uneven driving, and the existing leaf springs generally have disadvantages such as poor mechanical properties and low load-carrying capacity.

Embodiment Construction
[0020] Figure 1 to Figure 4 Shown is a kind of automobile frame-shaped leaf spring suspension embodiment of the present invention, and this suspension comprises frame-shaped leaf spring 1 and the supporting pin 2 that is fixed on the vehicle frame 3 of automobile, and frame-shaped leaf spring 1 is arranged by parallel The upper and lower two steel plates 11 are composed of two steel plates 11 with the same thickness. One end of the two steel plates 11 is connected as a whole through the bent ear joint 12, and the other end is open and forms the open end of the frame-shaped leaf spring 1. The bent ear connecting portion 12 is sleeved on the supporting pin shaft 2, and the open end of the frame-shaped leaf spring 1 is connected with the axle 4 of the automobile through a fastener 5. The frame-shaped leaf spring 1 is straight when no force is applied. When it is bent under force, in an ideal state, the deformation shapes of the upper and lower steel plates 11 are basically the s...

The invention discloses a suspension of a frame-shaped steel plate spring of an automobile. The suspension comprises a frame-shaped steel plate spring and a support hinge pin fixed on an automobile frame of the automobile, wherein the frame-shaped steel plate spring consists of upper and lower steel plates which are arranged in parallel; one ends of the two steel plates are integrally connected through a bending ear connecting part; the other ends of the two steel plates are opened and an opening end of the frame-shaped steel plate spring is formed; the bending ear connecting part is sleeved on the support hinge pin; and the opening end of the frame-shaped steel plate spring is connected with an axle of the automobile through a fastening piece. The suspension of the frame-shaped steel plate spring of the automobile has the advantages of being simple and practical in structure, strong in bearing capability, high in systematic reliability and capable of reducing the system weight.
Description
technical field [0001] The invention relates to an automobile suspension, in particular to an automobile frame-shaped leaf spring suspension. Background technique [0002] The leaf spring is an important part of the vehicle suspension system, which plays the role of bearing the weight of the vehicle body, transmitting forces and moments in all directions, and buffering and damping. Existing leaf springs are composed of a number of spring sheets with different lengths. Due to the direct contact between the reed sheets, each steel sheet will move up and down when the vehicle is running, resulting in friction, and this friction will interact to produce Noise, coupled with different deformation degrees of different steel plates, thus causing problems such as uneven driving, and the existing leaf springs generally have disadvantages such as poor mechanical properties and low load-bearing capacity. Contents of the invention [0003] The technical problem to be solved by the pre...
