Problems solved by technology

[0003] In the traditional technology, pure rubber mounts are used to meet the needs of automobile shock absorption and vibration isolation. Although the design and production costs are relatively low, the vibration damping effect is significantly reduced after a period of use due to the aging of rubber and the weakening of elasticity. , and the pure rubber mount has poor mitigation effect at low frequency vibration, and the pitch modal frequency of the main reducer of a certain car model is about 34Hz, and the pure rubber mount can not solve the vibration of the main reducer of the car

Embodiment 1

[0026] figure 1 It shows a structural schematic view of the vibration absorber installed on the main reducer of the automobile in this embodiment, figure 2 yes figure 1 A-A view in . In this embodiment, the shock absorber 200 is installed on the front trailing arm 100 of the final drive. The shock absorber 200 includes a mass block and an elastic block. The trailing arm 100 is in direct contact, and the mass blocks are arranged outside the elastic blocks on both sides, so that the elastic blocks are located between the mass block and the front trailing arm 100 of the final drive.

[0027] refer to figure 2 , the shock absorber 200 specifically includes a first elastic block 3 and a second elastic block 4 located on both sides of the front trailing arm 100 of the final drive. The two elastic blocks are directly in contact with the front trailing arm 100 of the final drive. The first mass block 1 and the second mass block 2 are respectively provided, that is, the first ela...

Embodiment 2

[0033] The structure of the vibration absorber for the main reducer of the automobile in this embodiment is similar to the structure of the vibration absorber in Embodiment 1, and the only difference lies in the composition of the mass block. In Embodiment 1, both the first mass block 1 and the second mass block 2 are made of an integral metal material such as steel or iron, and in this embodiment, in order to make the vibration absorber suitable for different vibration frequencies of the main reducer, the The first mass block 1 and the second mass block 2 are respectively arranged as structures with adjustable weights.

[0034] image 3 A schematic stacking diagram of the first mass 1 in this embodiment is shown, and the structure of the second mass 2 is the same as that of the first mass 1 . Specifically, the first mass 1 includes several unit blocks 9 stacked along its axial direction. The several unit blocks 9 are hollow cylinders with the same inner diameter and coaxial ...

Embodiment 3

[0037] The structure of the vibration absorber for the main reducer of the automobile in this embodiment is similar to the structure of the vibration absorber in Embodiment 2, the difference lies in the stacking manner of the unit blocks of the mass blocks.

[0038] Figure 4 A schematic stacking diagram of the first mass 1 in this embodiment is shown, and the structure of the second mass 2 is the same as that of the first mass 1 . Specifically, the first quality block 1 includes several unit blocks 9 stacked along its radial direction, and the several unit blocks 9 are hollow cylinders arranged coaxially, and the outer diameter of the innermost unit block is equal to the outer diameter of the unit nested outside it. block inner diameter, and so on, several unit blocks are set together in 9 sets. If the inner diameter of the unit block 9 of the outer layer is greater than the outer diameter of the nut 7, the outer unit block 9 will fall off. In order to avoid the above situa...

Abstract

The invention belongs to the technical field of automobile damping and denoising and discloses a vibration absorber for an automobile main reducing gear. The vibration absorber comprises mass blocks arranged at two sides of a front longitudinal arm of the main reducing gear and elastic blocks arranged between the mass blocks and the main reducing gear. According to the invention, the vibration absorber is arranged on the front longitudinal arm of the automobile main reducing gear, and the pitch vibration of the main reducing gear can be reduced through the interaction between the elastic blocks and the mass blocks, so that the requirement of the automobile main reducing gear for damping is met; and the vibration absorber is simple and practical integrally, and the mass blocks and the elastic blocks are controllable and adjustable and can adapt to the main reducing gears of different vibration frequencies so as to achieve the optimal vibration absorption and reduction effect.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorption and noise reduction, in particular to a shock absorber for an automobile final drive. Background technique [0002] The vehicle power assembly or transmission component assembly is directly connected to the body or indirectly through the frame, and the quality of its design directly affects the ride comfort of the car. As people have increasingly stringent requirements for vehicle vibration and noise control, this puts forward higher requirements for the design of vehicle powertrain or transmission component assembly, and some vibration reduction measures are needed to effectively reduce the vehicle powertrain or transmission Vibration of component assemblies. In fact, it is mainly necessary to reduce the vibration of the powertrain or transmission component assembly under one or several operating conditions. In the assembly of automobile transmission components, the main red...
