Description

Spring vibration isolation pad, shock absorber and vehicle

Technical Field

The disclosure relates to the technical field of vehicles, in particular to a spring vibration isolator, a vibration absorber and a vehicle.

Background

The spring vibration isolation pad is one of main components forming the vibration absorber assembly, and is arranged at the upper end and the lower end of the spring to play a role in absorbing vibration and eliminating abnormal sound.

Due to the structural principle of the shock absorber, if the two ends of the spring are directly installed on the spring tray in the movement process, a gap exists between the spring lift section and the spring tray in the spring compression and stretching processes, interference and abnormal sound can be generated, the spring and the spring tray are not in direct contact due to the vibration isolation pad, and the interference and the abnormal sound are avoided. Spring and vibration isolator relative motion can make the surface of vibration isolator rolled repeatedly, and the vibration isolator is easily worn and torn by the spring, is worn and torn even by the spring, and the vibration isolator can cause spring tray's lacquer coat to scrape to rust by wearing, and then leads to spring tray rust to wear, and the shock absorber function is inefficacy.

Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, without going to the contrary, the term "up" refers to the orientation or position relationship of the product that is usually placed when in use, and can be understood as upward along the gravity direction, which also corresponds to the "up" in the drawing; "inner and outer" refers to "inner and outer" relative to the contour of the component or structure itself. In addition, it should be noted that terms such as "first", "second", "third", and the like are used for distinguishing one element from another, and have no order or importance.

According to a first aspect of the present disclosure, a spring isolator is provided, referring to fig. 1 and 2, which includes an isolator body 2, one side of which isolator body 2 is provided with a wear layer 1.

Through above-mentioned technical scheme, owing to be provided with wearing layer 1 on vibration isolator body 2, can avoid spring 3 to roll vibration isolator body 2 repeatedly through this wearing layer 1 to can reduce the possibility of vibration isolator body 2 wearing and tearing, be favorable to prolonging the life of spring vibration isolator, and can prevent shock absorber function failure.

Referring to fig. 1 and 2, in the embodiment of the present disclosure, the wear-resistant layer 1 includes a fluororesin structure protruding from the surface of the vibration isolator main body 2, in other words, a portion of the fluororesin structure is located outside the surface of the vibration isolator main body 2, so that the fluororesin structure can contact the spring 3. Because the fluororesin structure has low friction and heat resistance, the fluororesin structure is positioned between the vibration isolator body 2 and the spring 3, and when the spring 3 and the vibration isolator body 2 generate relative motion, the fluororesin structure can avoid the contact between the spring 3 and the vibration isolator body 2, thereby preventing the vibration isolator body 2 from being worn and generating abnormal sound. In addition, the fluororesin structure has lower cost, and is beneficial to reducing the manufacturing cost of the spring vibration isolator.

In the embodiment of the present disclosure, the vibration isolator main body 2 is made of a rubber material, and the fluororesin structure is vulcanized integrally with the vibration isolator main body 2, so that the coupling strength between the fluororesin structure and the vibration isolator main body 2 can be enhanced. During processing, the fluororesin structure can be vulcanized with the vibration isolation pad body 2 into a whole when the vibration isolation pad body 2 is vulcanized, so that the processing difficulty can be reduced, and the processing efficiency can be improved. In some embodiments, the fluororesin structure may be bonded to the vibration insulator body 2 by using an adhesive.

Referring to fig. 2, in the embodiment of the present disclosure, the mounting groove 21 is formed on the vibration isolation pad body 2, at least a portion of the wear-resistant layer 1 is disposed in the mounting groove 21, and by disposing the mounting groove 21, it is beneficial to vulcanize the fluororesin structure and the vibration isolation pad body 2 into a whole, that is, a portion of the wear-resistant layer 1 is vulcanised inside the vibration isolation pad body 2, so that the structural strength of the vibration isolation pad body 2 and the wear-resistant layer 1 can be strengthened.

In the embodiment of the present disclosure, the wear-resistant layer 1 is configured in an arc shape, and the length of the wear-resistant layer 1 is approximately one fourth of the circumference of the spring 3, so that the wear-resistant layer 1 can be matched with the end part of the spring 3, and the wear of the spring 3 on the vibration isolation pad body 2 is reduced.

Referring to fig. 1 and 3, according to a second aspect of the present disclosure, a shock absorber is provided, where the shock absorber includes a spring 3 and two spring vibration isolators as described above, where the spring 3 is disposed between the two spring vibration isolators, and two ends of the spring 3 are correspondingly in contact with the wear-resistant layers 1 of the two vibration isolator bodies 2, so as to reduce the wear of the spring 3 on the vibration isolator bodies 2 through the wear-resistant layers 1, which is beneficial to prolonging the service life of the shock absorber.
