Adopt above-mentioned technical scheme, because be equipped with the pin that is used for connecting wheel shell and wheel carrier in the mounting hole and be used for reducing the damping device that the wheel carrier received the vibration power that comes from the transmission of hub, damping device is including the cushion that lies in between pin and the mounting hole and connect the first damping spring between cushion and wheel carrier, when meetting unevenness's road surface, the vibration power that wheel hub received transmits to the wheel carrier, cushion can offset a part of vibration power, the vibration power that transmits to the case and bag also reduces thereupon, for example meet the road surface during protruding, wheel hub upward movement, because be equipped with first damping spring between cushion and the wheel carrier, first damping spring's shortening distance is less than the distance that wheel hub upward movement, can reduce the sense of vibration of case and bag, compare in the structure of traditional band pulley case and bag, good shock attenuation effect has.
The utility model discloses a further setting: the damping cushion block is cylindrical, the damping device further comprises a limiting sleeve movably connected to the damping cushion block and a plurality of fixing rods hinged to the limiting sleeve, one end of each fixing rod is connected to the limiting sleeve, and the other end of each fixing rod is fixedly connected to the inner wall of the mounting hole.
Adopt above-mentioned technical scheme, because the cushion block is cylindrically, be equipped with stop collar and hinged joint in the a plurality of dead lever of stop collar on the cushion block, when can preventing that cushion block from taking place the displacement, the skew center pin of mounting hole of cushion block's center pin guarantees that damping device can not break down.
The utility model discloses a further setting: damping device still includes twines in the second damping spring of cushion, second damping spring one end fixed connection is in the stop collar, and the other end is connected in the pin.
Adopt above-mentioned technical scheme, because second damping spring one end fixed connection in stop collar, the other end is connected in the pin, can further improve damping device's shock attenuation effect.
The utility model discloses a further setting: the quantity of dead lever is 4, and 4 dead levers evenly encircle in the stop collar.
Adopt above-mentioned technical scheme, because the quantity of dead lever is 4, and 4 dead levers evenly surround in the stop collar, guarantee the center pin of stop collar and the center pin coincidence of mounting hole, when can preventing that the cushion block from taking place the displacement, the skew center pin of mounting hole of cushion block's center pin guarantees that damping device can not break down.
The utility model discloses a further setting: the shock absorption cushion block is made of rubber.
By adopting the technical scheme, the rubber material has the characteristics of low use cost and good damping effect, and the damping cushion block uses the rubber material which can further improve the damping effect of the damping device.
Drawings
Fig. 1 is a sectional view of a multistage damping wheel hub for a luggage of the embodiment of the present invention.
Fig. 2 is a partial enlarged view of a multistage damping wheel hub for a luggage of the present invention.
The damping device comprises a wheel frame 1, a wheel hub 2, a wheel shell 3, a mounting hole 4, a pin 5, a damping device 6, a damping cushion block 7, a first damping spring 8, a limiting sleeve 9, a fixing rod 10 and a second damping spring 11.
Detailed Description
As shown in fig. 1-2, the multistage damping wheel hub for luggage comprises a wheel frame 1, a wheel hub 2 slidably connected to the wheel frame 1, and a wheel shell 3 for protecting the wheel frame 1, wherein a mounting hole 4 is formed in the wheel frame 1, a pin 5 for connecting the wheel shell 3 and the wheel frame 1 and a damping device 6 for reducing the shock force transmitted from the wheel hub 2 to the wheel frame 1 are arranged in the mounting hole 4, and the damping device 6 comprises a damping cushion block 7 located between the pin 5 and the mounting hole 4 and a first damping spring 8 connected between the damping cushion block 7 and the wheel frame 1.
Since the pin 5 for connecting the wheel housing 3 and the wheel frame 1 and the damping device 6 for reducing the shock force transmitted from the wheel hub 2 to the wheel frame 1 are provided in the mounting hole 4, the damping device 6 includes a damping pad 7 between the pin 5 and the mounting hole 4 and a first damping spring 8 connected between the damping pad 7 and the wheel frame 1, when the wheel hub meets an uneven road surface, the vibration force received by the wheel hub 2 is transmitted to the wheel carrier 1, the shock absorption cushion block 7 can counteract a part of the vibration force, the vibration force transmitted to the luggage is reduced, for example, when the road surface meets an uneven road surface, the wheel hub 2 moves upwards, because the first damping spring 8 is arranged between the damping cushion block 7 and the wheel carrier 1, the shortening distance of the first damping spring 8 is less than the upward movement distance of the wheel hub 2, can reduce the vibration of case and bag, compare in the structure of traditional band pulley case and bag, have good shock attenuation effect.
Because cushion block 7 is cylindrical, be equipped with stop collar 9 and hinged joint in a plurality of dead lever 10 of stop collar 9 on cushion block 7, when can prevent that cushion block 7 from taking place the displacement, the skew center pin of mounting hole 4 of the center pin of cushion block 7 guarantees that damping device 6 can not break down.
Damping device 6 still includes twines in the second damping spring 11 of cushion 7, second damping spring 11 one end fixed connection is in stop collar 9, and the other end is connected in pin 5.
Because second damping spring 11 one end fixed connection is in stop collar 9, and the other end is connected in pin 5, can further improve damping device 6's shock attenuation effect.
The number of the fixing rods 10 is 4, and the 4 fixing rods 10 evenly surround the limiting sleeve 9.
Because the quantity of dead lever 10 is 4, and 4 dead levers 10 evenly encircle in stop collar 9, guarantee the center pin of stop collar 9 and the center pin coincidence of mounting hole 4, when can preventing that cushion block 7 from taking place the displacement, the skew mounting hole 4's of cushion block 7 center pin guarantees that damping device 6 can not break down.
The damping cushion block 7 is made of rubber.
Because the rubber material has low in use cost, the effectual characteristics of shock attenuation, the cushion block 7 uses the rubber material can further improve damping device 6's shock attenuation effect.
