Problems solved by technology

However, in order to achieve a certain damping effect, the dynamic shock absorber is required to have a larger mass, which will increase the curb weight of the vehicle, thereby increasing the cost of manufacturing and using the vehicle.

Embodiment Construction

[0021] An example of a vehicle in the present invention is Figure 1~Figure 4 As shown, it is a commercial vehicle with a vibration-absorbing spare tire bracket, including a vehicle frame 10, a spare tire bracket 20 and a spare tire 30, and the spare tire bracket 20 includes a lifter main body 21, a lower pallet 22, a rocker 23 and a lift Rope, the spare tire 30 is connected on the lower supporting plate 22 of the spare tire rack 20, and the lower supporting plate 22 and the spare tire 30 can be driven up and down by shaking the rocker 23 through the lifting rope, so that the spare tire 30 can be put away and put down. 30 can be fixed together with spare tire frame 20 when packing up. The above-mentioned lifting method of the spare tire 30 is a commonly used prior art, and the structures of the lifter main body 21, the lower supporting plate 22, the rocking bar 23 and the lifting rope will not be described in detail here.

[0022] The vehicle frame 10 includes a longitudinal ...

Abstract

The invention relates to a vibration damping device, a vehicle spare tire support and a vehicle using the device. Wherein the damping device comprises a spare tire frame connector for connecting with the spare tire frame and a vehicle frame connector for connecting with the vehicle frame, an elastic The buffer part is elastically connected by the elastic buffer part. Therefore, after the spare tire is installed on the spare tire rack, the spare tire itself can constitute the mass block of the mass spring resonance system, thereby forming a dynamic shock absorber together with the elastic buffer block to attenuate the vibration of the vehicle. Due to the vibration generated by the resonance of the unsprung mass, since the spare tire belongs to the original item on the vehicle, it will not increase the curb weight of the spare tire vehicle, and at the same time achieve a good vibration reduction effect, improve the comfort of the vehicle and the life of the vehicle.

Description

technical field [0001] The invention relates to a vibration damping device, a vehicle spare tire support and a vehicle using the device. Background technique [0002] The sprung bias frequency and unsprung bias frequency of the vehicle are the natural frequencies of the vehicle. When the vehicle reaches a certain speed, the excitation frequency of the road surface will coincide with the unsprung bias frequency of the vehicle, and the unsprung mass will resonate at this time And the vibration is transmitted to the interior of the vehicle, which seriously affects the ride comfort and comfort of the vehicle, deteriorates the NVH performance of the vehicle, and affects the reliability and durability of the vehicle. [0003] In order to avoid the above-mentioned problems caused by unsprung bias frequency, in the prior art, a dynamic vibration absorber is often used to attenuate the vibration of the vehicle body. A dynamic vibration absorber is a device that uses a resonance syste...
