Abstract

The utility model provides a leaf spring assembly which comprises a leaf spring set. The leaf spring set is formed by assembling a plurality of single-leaf leaf springs together by center bolts or U-shaped clips through a certain prestress; galvanized sheet steel liners are arranged between every two spring leaves at intermediate positions of the leaf spring set; and noise reducing sheets made of polymer polyethylene or polyformaldehyde are arranged between every two spring leaves at the ends of the leaf spring set. As the noise reducing sheets are arranged at the ends of the leaf spring leaf set, the use noise caused by the direct contact of respective leaf spring leaves is eliminated; meanwhile, uniform gaps are formed between the respective leaf springs through arranging the liners at the intermediate positions of the leaf spring set, therefore, the occurrence of a contact fatigue source is avoided, the service life of the leaf springs is prolonged, and the problem of the noise produced by the plurality of spring leaves is solved fundamentally; at the same time, the service life of the plurality of leaf springs can be greatly prolonged.

Description

A kind of steel plate spring assembly
Technical field
The utility model relates to automobile leaf spring series assembly.
Background technique
Leaf spring is a vitals in the vehicle suspension system, Multi-Leaf Springs is simple because of technology, cost of production is low, use very extensive, but because traditional Multi-Leaf Springs is by centre bolt or U bolt a plurality of monolithics to be fitted together by certain prestressing, fit tightly between each sheet in theory, in use because the vibration of leaf spring, relative movement appears between each sheet, noise is inevitable, and the early fracture of leaf spring all originates from the contact fatigue point between each sheet simultaneously.Multi-Leaf Springs is widely used on cargo vehicle and the passenger vehicle, and along with the further raising that people require ride comfort, the sufficient especially passenger vehicle of noise problem uses noise more and more to receive publicity.
Summary of the invention
The utility model directly contacts use noise that causes and the appearance raising leaf spring working life of avoiding the contact fatigue source in order to have eliminated each sheet of leaf spring, and the spy proposes a kind of steel plate spring assembly.
The technical solution of the utility model is for this reason, a kind of steel plate spring assembly, comprise the leaf spring group, the leaf spring group is by centre bolt or U type clamp a plurality of single-leaf springs to be fitted together by certain prestressing, it is characterized in that:, be provided with liner between per two spring sheets in the intermediate portion of leaf spring group; In the end of leaf of spring group, be provided with the noise reduction sheet between per two spring sheets.
Improvement to such scheme is: described liner is a galvanized sheet metal; The noise reduction sheet is made with high-molecular polythene or polyformaldehyde material.
Beneficial effect:
The utility model has been eliminated the use noise that the direct contact of each sheet of leaf spring causes owing to install the noise reduction sheet additional in the end, makes each sheet of leaf spring the appearance raising leaf spring working life that the contact fatigue source is avoided in uniform gap occur by install liner additional in the intermediate portion simultaneously.The utility model has fundamentally solved the noise that multiple-leaf spring produces; Be used for bus market in batches the working life that simultaneously can improve Multi-Leaf Springs greatly, and Market Feedback is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged diagram that A of the present utility model is ordered.
Fig. 3 is the enlarged diagram that B of the present utility model is ordered.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3.
Steel plate spring assembly leaf spring 1,2,3,4,5,6,7,8,9,10 totally ten leaf springs composition cluster spring are utilized bolt 11 and U type clamp 12, and it is formed a steel plate spring assembly.
The utility model is in the intermediate portion of leaf spring group, is provided with liner 13 between per two spring sheets; In the end of leaf of spring group, be provided with noise reduction sheet 14 between per two spring sheets.
Liner 13 is a galvanized sheet metal; Noise reduction sheet 14 usefulness high-molecular polythenes or polyformaldehyde material are made.
