Problems solved by technology

However, this structural scheme also has obvious deficiencies. First, the structure is relatively complex, requiring relatively many parts and manufacturing processes, and several rubber parts are required to be vulcanized separately (such as upper and lower limit rubber blocks, working rubber blocks vulcanization), welding (such as installation Second, the rigidity of the rubber after vulcanization cannot be adjusted, and unqualified products cannot be effectively reworked and repaired, and cannot 100% meet the natural frequency requirements. The cost is high, and there are limitations in popularization and use.

Abstract

A mass shock absorber for a rear axle, relating to a shock absorber, comprising a screw, a mass inertial block, vibration-absorbing rubber, and a mounting bracket. Set on both sides of the vertical plate, each mass inertia block is provided with a central round hole, and the mass inertia block and the vertical plate are connected by vibration-absorbing rubber vulcanization; the screw rod is inserted into a gasket, nut, and buffer rubber sleeve, and the screw rod passes through The central circular hole of the mass inertia block, the vibration-absorbing rubber, the limit hole of the vertical plate, and the buffer rubber sleeve is located in the limit hole of the vertical plate, and the two mass inertia blocks, the two vibration-absorbing rubbers and the vertical plate are connected by gaskets and nuts. The plates are locked together and the amount of lateral compression or tension deflection of the vibration-absorbing rubber can be adjusted. The invention can reduce vibration and noise, can freely adjust the stiffness after rubber vulcanization molding, has good safety performance, can improve the NVH performance of the whole vehicle, shortens the research and development cycle of the vehicle or shock absorber products, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a rear axle mass shock absorber. Background technique [0002] With the continuous improvement of automobile ride comfort and noise requirements, solving the vibration and noise problem of the rear drive axle of automobiles has become the main research content of NVH engineers in the domestic automobile industry. There are many reasons for the vibration and noise of the rear drive axle. The main reason is that the vibration of the unbalanced inertial force of the engine crankshaft is transmitted through the torsional vibration of the drive shaft, and the coupling resonance with the vibration of the unsprung mechanism and tires occurs at or near the rear axle. Under the existing conditions, installing a mass shock absorber on the rear drive axle is a more economical and effective means to reduce or eliminate the vibration and noise of the rear axle. [0003] Design and control the natural fr...
