Including hollow cylindrical damper cylinder, one end of a central shaft is set with the cylindrical damper cylinder, the central shaft
Excircle is cased with a damping spring, and the other end of the central shaft is socketed with one can carry out 360 by axle center of central shaft
The flat bearing of degree rotation, the bottom of the flat bearing arranges roller fixing base, and the bottom of the roller fixing base is provided with
Roller.
Overhead gage is provided with the top of the cylindrical damper cylinder, the bottom of the cylindrical damper cylinder is provided with lower block
Plate.
The upper hollow ring for being provided centrally with being available for central shaft top to pass through of the overhead gage.
Space between the overhead gage of the both sides at the top of the central shaft, the top of damping spring and cylindrical damper cylinder
One top anti-friction bearings is inside respectively installed.
The lower hollow ring for being provided centrally with being available for central shaft bottom to pass through of the lower baffle plate.
One bottom anti-friction bearings is respectively installed in the position that the lower hollow ring both sides contact with central shaft.
A spacing collar is provided with the bottom of the central shaft, the excircle of the central shaft of close lower baffle plate.
A rubber buffer ring is provided with the lower baffle plate, towards the side of spacing collar.
Internal diameter of the external diameter of the flat bearing more than lower hollow ring.
The bottom of the cylindrical damper cylinder is additionally provided with installation otic placode, for this device to be arranged on into bottom of luggage case.
A kind of novel damping type luggage wheel assembly described in this patent, when the roller of luggage case it is up in rugged road
When walking, central shaft can be made to move up and down in cylindrical damper cylinder in the presence of damping spring and roller, so as to alleviate luggage
The vibration of case, article in guard box；Meanwhile, the setting of flat bearing can ensure that roller can carry out 360 degree of rotations so that whole row
Lee's case turns to flexible；Further, the design of top anti-friction bearings and bottom anti-friction bearings, by sliding friction rolling is converted into
Dynamic friction, can significantly mitigate the friction between central shaft and cylindrical damper cylinder, extend the service life of the shock mitigation system；Most
Afterwards, by the setting of rubber buffer ring, the noise in luggage case dragging process can be effectively reduced, lifts the quality of luggage case.
This patent overall structure is simple and reliable, design ingenious, good damping effect, long service life, can large-scale promotion make
With.
