Technical Field

[0001] The utility model relates to the technical field of vehicle axles, in particular to a wheel side spacer for vehicle axles which is convenient for gas circulation. Background Art

[0002] Chinese patent publication number CN205979100U discloses "a wheel side spacer for a vehicle axle", which includes a spacer body, at least four primary through holes are evenly distributed radially on the outer circumference of the spacer body, at least four secondary through holes are evenly distributed axially on one end face of the spacer body, the primary through holes correspond to the secondary through holes one by one, and any of the primary through holes is connected to the corresponding secondary through holes to form an L-shaped spacer vent hole; the utility model combines the primary through holes arranged radially and the secondary through holes arranged axially on the wheel side spacer into an L-shaped spacer vent hole structure, and the vent hole structure can facilitate the arrangement of the wheel side air pipe of the axle charging and discharging structure, and the air pipe passes through the spacer vent hole to ventilate with the outside, and the structure is compact and reliable. At the same time, the vent holes on the wheel side spacer of the utility model can also be used as oil channels to provide more sufficient oil lubrication for the axle wheel side.

[0003] Although the above scheme is convenient for ventilation with the outside world, is compact in structure, and is also conducive to lubrication, since the path connecting the primary through hole and its corresponding secondary through hole is relatively single, when one end is blocked, it will affect the overall ventilation effect. For this reason, a wheel side spacer for an axle that facilitates gas circulation is proposed. Summary of the invention

[0004] The utility model aims to provide a wheel side spacer for a vehicle axle which is convenient for gas circulation, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wheel side spacer for a vehicle axle that facilitates gas circulation, comprising a spacer body, air holes are arranged on both sides of the outer circumference of the spacer body, and connecting holes are arranged between the air holes;

[0007] The communicating hole is provided with a branch channel, and both ends of the branch channel are connected to the communicating hole;

[0008] An auxiliary vent hole is provided along the axial direction on one end surface of the spacer body, and the auxiliary vent hole is communicated with the branch channel;

[0009] The ventilation holes, the connecting holes, and the branch channels constitute ventilation structures, and the ventilation structures are connected to each other.

[0010] Furthermore, the connection between the vent hole and the connecting hole is bent and has rounded corners.

[0011] Furthermore, the connection between the branch channel and the connecting hole is bent and has rounded corners.

[0012] Furthermore, a communication channel 1 is provided between the vent holes.

[0013] Furthermore, a second interconnecting channel is provided between the branch channels.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The problem that the path connecting the primary through hole and its corresponding secondary through hole is relatively single, and when one end is blocked, the overall ventilation effect will be affected, a multi-end ventilation design is adopted, and a connecting structure is set between each air hole for comprehensive ventilation, which is conducive to airflow and will not affect the overall ventilation effect due to the blockage of one channel.
