Abstract
The utility model relates to an automobile rearmost axle damping device used for reducing vibration of an automobile rearmost axle and noise in the automobile. The device comprises a mounting bracket, quality iron blocks, damping rubber bands, bolts and a shaft housing, wherein the damping rubber bands are arranged in depressions at two sides of an extension board, the shaft housing is arranged in the damping rubber bands, the quality iron blocks cling to the exterior of the damping rubber bands, the raised parts of the quality iron blocks are arranged in the damping runner bands, and the extension board, the quality iron blocks, the damping rubber bands and the shaft housing are fixed together through bolts. By reducing the vibration of the rearmost axle peak frequency and absorbing the vibrational energy of the rearmost axle peak frequency, the utility model can reduce the amplitude of the rearmost axle, reduce roar in the automobile and improve the riding comfort of passengers.
Description
Technical field
The utility model relates to automobile vibration noise field, relates in particular to a kind of device that reduces the automobile axle vibration, reduces internal car noise.
Background technology
Automobile is generally used by people as a kind of important vehicle.But automobile in the process of moving, when driving engine gives it the gun from slow speed of revolution, the torsional oscillation of driving engine can be delivered to back axle by driving system, and cause the vibration of back axle, be delivered to vehicle frame, vehicle body by suspension again, in car, produced a kind of roar of low frequency, made the interior passenger of car feel very uncomfortable.Along with the raising of people's quality of life, the noise of automobile and vibration are paid close attention to by people also more and more, and people wish to have a kind of device to reduce vibration and the noise that produces in the driving engine torsional oscillation process.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of automobile axle shock absorption device, by the vibration of decay back axle crest frequency, the vibrational energy of absorption back axle crest frequency, reaches the effect that reduces the back axle Oscillation Amplitude, reduces roar in the car.
The utility model is achieved by the following technical programs:
A kind of automobile axle shock absorption device, by mounting bracket, the quality iron block, the damping rubber circle, bolt and axle sleeve constitute, wherein, described mounting bracket is made of panel and support plate, and panel and support plate vertical fixing link together, the support plate two sides is equipped with the depression that adapts with damping rubber circle external diameter, the quality iron block is provided with projection, the diameter of bossing is slightly less than damping rubber circle internal diameter, the damping rubber circle places in the depression on support plate two sides, and axle sleeve places in the damping rubber circle, and the quality iron block is close to outside the damping rubber circle, the bossing of quality iron block places in the damping rubber circle, and bolt is with support plate, the quality iron block, damping rubber circle and axle sleeve are fixed together.
The length of described axle sleeve is close to the distance between latter two projection outside the damping rubber circle for the quality iron block.
The area of contact of described damping rubber circle and quality iron block is 6-10cm
2, the quality of automobile axle shock absorption device is 3.0-3.4kg, can reduce the noise of 35-55Hz frequency.
Principle of work of the present utility model is: natural frequency of the present utility model is designed to identical with back axle single order torsional frequency, and be fixedly mounted on the back axle by panel, when the torsional oscillation of engine accelerating course is delivered to back axle by driving system, and when its oscillation frequency reaches back axle single order torsional frequency, the automobile axle shock absorption device just begins resonance, the damping rubber circle absorbs most vibrational energy, reduces the Oscillation Amplitude of back axle, reduces the noise that thunders in the car.
The beneficial effects of the utility model are: by the vibration of decay back axle crest frequency, the vibrational energy of absorption back axle crest frequency, can reach the effect that reduces the back axle Oscillation Amplitude, reduces roar in the car, improve the comfort level that the interior passenger of car takes advantage of seat.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A part sectional view of the utility model Fig. 1;
Among the figure, 1 mounting bracket, 2 quality iron blocks, 3 bolts, 4 damping rubber circles, 5 axle sleeves, 6 support plates, 7 panels.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of automobile axle shock absorption device, by mounting bracket 1, quality iron block 2, damping rubber circle 4, bolt 3 and axle sleeve 5 constitute, wherein, mounting bracket 1 is made of panel 7 and support plate 6, and panel 7 links together with support plate 6 vertical fixing, support plate 6 two sides are equipped with the depression that adapts with damping rubber circle 4 external diameters, quality iron block 2 is provided with projection, the diameter of bossing is slightly less than damping rubber circle 4 internal diameters, damping rubber circle 4 places in the depression on support plate 6 two sides, axle sleeve 5 places in the damping rubber circle 4, quality iron block 2 is close to outside the damping rubber circle 4, the bossing of quality iron block 2 places in the damping rubber circle 4, and bolt 3 is with support plate 6, quality iron block 2, damping rubber circle 4 and axle sleeve 5 are fixed together, and the length of axle sleeve 5 is that quality iron block 2 is close to the distance between damping rubber circle 4 outer latter two projectioies.
Damping rubber circle 4 is 8cm with the area of contact of quality iron block 2
2
The quality of automobile axle shock absorption device is 3.2kg.
The natural frequency of the automobile axle shock absorption device of present embodiment is 45Hz, identical with back axle single order torsional frequency, and be fixedly mounted on the back axle by panel, when the torsional oscillation of engine accelerating course is delivered to back axle by driving system, and when its oscillation frequency reached 45Hz, the automobile axle shock absorption device just began resonance, and the damping rubber circle has absorbed most vibrational energy, reduce the Oscillation Amplitude of back axle, reduce the noise that thunders in the car.
