Technical Field

The utility model relates to an automobile parts, concretely relates to high strength absorbs damper that rotates in a flexible way soon.

Background

The damper is widely applied to the industries of aerospace, aviation, war industry, machinery and the like, is a device for providing motion resistance to reduce motion capability, and mainly plays a role in energy dissipation and shock absorption. Such as: in the gravity type goods shelf storage, goods are accelerated in an inclined storage slideway due to the influence of gravity; if the goods are allowed to move freely, the goods impact the goods shelf, which may cause goods damage, potential safety hazards of operators and damage to the overall structure of the goods shelf; in which the damper plays a very important role; the damper in the gravity type goods shelf, also called as a speed reducer, is mainly used for eliminating the gravity acceleration generated by goods in the gravity type goods shelf.

Dampers are also widely used in the automotive industry. A attenuator for cable and selector are connected, its aim at reduce cable transmission resonance, promote the performance of shifting. In the prior art, the damper for connecting the inhaul cable and the gear shifter has the defects of large friction resistance, inflexible rotation, slow response, low vibration transmission efficiency, easy cracking or fracture of rubber, short service life and the like, so that the controllability and the comfort of the whole vehicle are influenced.

SUMMERY OF THE UTILITY MODEL

To the defect that prior art exists above, the utility model aims to provide a high strength absorbs the attenuator that rotates in a flexible way soon, and it can carry out quick response to resonance and high-efficient transmission and absorption resonance, has high strength, frictional resistance simultaneously little, rotates nimble characteristics.

The utility model discloses a following technical scheme realizes:

the utility model provides a nimble attenuator is rotated in fast absorption of high strength which characterized in that: it is composed of a rubber sleeve and a metal inner framework; the metal inner framework is of a cylindrical structure, is hollow in the middle and is used for connecting a pull cable and a gear shifter; the rubber sleeve uniformly coats the metal inner framework, and a recessed angle is formed between the rubber sleeve and contact points of the upper end and the lower end of the metal inner framework and is annular; the two ends of the rubber sleeve are large, the middle of the rubber sleeve is small, and the joints of the middle part of the rubber sleeve and the upper and lower ends of the rubber sleeve are respectively provided with an inward concave annular round angle; a plurality of bosses are uniformly distributed on the upper end face and the lower end face of the rubber sleeve, the number of the bosses is not less than two, and the bosses correspond to the positions of the upper end and the lower end of the rubber sleeve.

Through the combined design of metal inner frame and sunk angle, the deformation space of contact point is provided, thereby the problem of metal inner frame because the inherent characteristic of the metal of itself influences the rubber sleeve transmission vibration, avoids the production of mechanical abnormal sound has been solved, cooperates the deformation space of annular fillet simultaneously, has improved the resonant efficiency of attenuator transmission greatly, reaches the resonant purpose of quick absorption.

Through the design of the lug boss, the contact surface between the damper and an external part is reduced, so that the friction damping is reduced, and the damper is flexible to rotate; meanwhile, the design of the lug boss enables resonance to be concentrated on one point and not to be dispersed on the whole contact surface, so that vibration can be transmitted and absorbed more quickly and efficiently. The structural combination of the whole rubber sleeve is adopted, so that each part of the rubber reasonably absorbs the fatigue strength of the vibration rubber which is locally received by the vibration rubber, the rubber sleeve is prevented from cracking or breaking, and the service life of the damper is prolonged.

Further optimized, in order to more efficiently absorb resonance and ensure the deformation amount of the rubber, the radius of the annular fillet is 0.5 mm.

Further optimization is carried out, in order to respond to resonance more quickly and ensure that the damper rotates flexibly and has small friction force, the bosses are circular bosses, and the number of the bosses is four.

The utility model discloses has following technological effect:

the utility model provides a damper for cable and selector are connected, and it has the characteristics that reach quick response, high-efficient absorbed vibration, and simultaneously, its frictional resistance is little, rotate nimble, long service life, satisfies the requirement that whole car travelling comfort and nature controlled combined together.
