Description
Technical field
This utility model is related to damping part, especially a kind of damping device for central electric eddy speed damper.
Background technology
The central electric eddy speed damper of home and abroad is arranged on truck, car, on special-purpose vehicles when for improve the retarder life-span and
The comfortableness of vehicle, need to install shock-damping structure.The circular cushion of generally two, existing cushion group structure, centre is installed with set
Cylinder, cushion are plane, sleeve and support directly contact with support assorted face；The fixed form of cushion group is typically by single
Spiralock nuts tighten fixation.This cushion group structure make vehicle in running because retarder mounting bracket and sleeve it
Between relative motion, cushion hardness and decrement reason cause vehicle abnormal sound and vibrations, affects relaxing in vehicle travel process
Appropriateness, makes cushion group easily damaged, while affecting vehicle service life.
In view of the foregoing, the structure of existing cushion group needs to improve.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind puts electric vortex buffering in being used for
The damping device of device, solves what vehicle was caused because of the relative motion between retarder mounting bracket and sleeve in running
Abnormal sound, vibrations, solve the vehicle vibration caused because of cushion hardness and decrement reason, effectively lift damping performance, structure
Simply, easy for installation, principle understands, it is not necessary to special manufacture and manufacturing process, it is easy to accomplish, security reliability is strong, improves
The comfortableness of vehicle and safety.
This utility model to achieve these goals, is adopted the following technical scheme that：It is a kind of to be used for central electric eddy speed damper
Damping device, be by：Bolt, plain cushion, crossbeam installing plate, upper cushion, lower convex platform, sleeve, gap, damping, buffering cavity,
Mounting bracket, lower cushion, bottom boss, packing ring, flange, nut are constituted；Plain cushion, big is set gradually by head to afterbody on bolt
Beam installing plate, sleeve, packing ring, plain cushion, nut, arrange mounting bracket in the middle part of sleeve periphery, reserve between sleeve and mounting bracket
Gap, arranges upper cushion between mounting bracket and crossbeam installing plate, lower cushion, sleeve are arranged between mounting bracket and packing ring
Damping, buffering cavity is reserved between top and crossbeam installing plate, the lower central of upper cushion arranges lower convex platform, and lower convex platform is arranged
In the gap.
The lower convex platform adopts hollow cylindrical structure, and lower convex platform is integrally formed with upper cushion.
Bottom boss is set in the middle part of the lower section of the lower cushion, and lower cushion is integrally formed with bottom boss, on the packing ring
The edge on surface arranges flange, and bottom boss is arranged at flange inner.
The afterbody of the bolt arranges at least two nuts.
The beneficial effects of the utility model are：This utility model upper cushion lower central arrange lower convex platform, under it is convex
Platform is arranged in the preset clearance between sleeve and mounting bracket, is prevented effectively from sleeve and mounting bracket directly contact, is solved
Vehicle abnormal sound that vehicle is caused because of the friction between retarder mounting bracket and sleeve in running, vibrations；Mounting bracket
The lower cushion of lower section is plane with the mating surface of mounting bracket, is easily installed；Using double nuts structure, single nut knot is solved
Structure anti-loosing effect is bad, the problem that nut comes off；Sleeve is installed with the centre bore of upper cushion and lower cushion, above sleeve
Damping, buffering cavity is reserved between crossbeam installing plate, the decrement of upper and lower cushion can be controlled by sleeve, solve because
The vehicle vibration that cushion decrement reason is caused；The cushion of different hardness, solution are adopted to the retarder main frame of Different Weight
Determine the vehicle vibration caused because of cushion hardness reason.
This utility model is arranged on truck, car, special-purpose vehicles etc., has a safety feature, and effectively lifts damping performance, structure letter
Single, easy for installation, principle understands, it is not necessary to special manufacture and manufacturing process, it is easy to accomplish, security reliability is strong, solves car
The abnormal sound that causes because of the relative motion between retarder mounting bracket and sleeve in running, vibrations, solve because subtracting
The vehicle vibration that shake pad hardness and decrement reason are caused.Between sleeve and mounting bracket, preset clearance efficiently avoid slowly
Hard link between device mounting bracket and sleeve, it is to avoid vehicle is in running because between retarder mounting bracket and sleeve
Abnormal sound that relative motion is caused, vibrations, improve comfortableness and the safety of vehicle.Current vortex retarder master to Different Weight
Cushion of the machine using different hardness.
