Description
Technical field
The invention belongs to endless-track vehicle wheel noise reduction technology fields, and in particular to one kind is used for endless-track vehicle thrust wheel
Hybrid particles damper.
Background technique
Endless-track vehicle can overcome certain landform limitation to require, and be widely used in building and machinery industry.But its operating condition one
As all under the conditions of " non-road surface ", rugged environment is very violent to its vibratory impulse.Meanwhile violent vibration and noise is to ring
Border pollution and crew comfort influence serious.Wherein thrust wheel is as crawler dozer primary load bearing structure part, thrust wheel
Cushion performance directly influences vehicle and driver.
Therefore, in order to guarantee the reliability and comfort of endless-track vehicle, following manner is generallyd use at present and carries out thrust wheel
Vibration damping: Chinese patent CN 101525009A and Chinese patent CN 108773423A individually discloses the buffering knot for thrust wheel
Structure device is utilized sliding type damping device and connects with hinged-support by changing the rigid connection of conventional track vehicle thrust wheel
Vibration damping is carried out, endless-track vehicle impact of collision and the impact of ground normal direction are reduced.
Practice have shown that being conceived to thrust wheel and vehicle body connecting portion buffer shock-absorbing with upper type, there is no fundamentally
In view of thrust wheel vibration damping, thrust wheel certainly will will affect Zhi Chong as the main load carrier of endless-track vehicle, violent impact vibration
Take turns service life and vehicle vibration.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of hybrid particles damper for endless-track vehicle thrust wheel,
The damping capacity of thrust wheel can be improved in the damper.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:
A kind of hybrid particles damper for endless-track vehicle thrust wheel, including thrust wheel wheel body and damping particles, the Zhi Chong
It takes turns wheel body and is equipped with the cavity for accommodating damping particles, the thrust wheel wheel body is equipped with the sealing cover for sealing cavity, described
Supporting element is equipped in cavity.
The supporting element is coupled by screw thread with the inner wall of cavity, and the supporting element is equipped with nut.
The sealing cover is coupled by bolt with thrust wheel wheel body.
The shape of the damping particles is spherical shape.
The cavity is equipped with three to five, and is evenly distributed along the circumferencial direction of thrust wheel wheel body.
Compared with prior art, the present invention having the beneficial effect that
Filling mixing damping particles, have carried out Vibrant buffer to thrust wheel, have combined metallic particles bandwidth on thrust wheel, have
There is impact force small, the advantages of noise is low, and structure is light, high temperature high voltage resistant, and wearability is good, high breaking strength and elongation.
It is provided with supporting element, guarantees the strength and stiffness of thrust wheel, reasonable integral structure, additional mass is small, cost of manufacture
It is low, it is easy to damp adjusting.
