Description

Lightweight hub unit

Technical Field

The utility model belongs to the technical field of automobile parts, particularly relates to the technical field of hub units, and particularly relates to a hub unit capable of automatically radiating heat.

Background

The hub unit is mainly used for bearing and providing accurate guide for the transmission of the hub, bears axial load and warp load, and is an important part in automobile parts. The traditional automobile hub unit comprises a flange, a ball, an inner ring, an outer ring and the like. When an automobile runs, the hub unit generates heat due to friction, particularly, the friction force is increased after the hub unit is used for a long time, and the hub unit is easy to further wear due to overhigh temperature of the hub unit when the automobile runs at a high speed, and even the spontaneous combustion of a tire is caused to generate accidents.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a light-weight hub unit which can automatically circulate and convey water to cool the hub unit when an automobile runs, slow down the abrasion of the hub unit and prevent the spontaneous combustion of a tire caused by overhigh temperature.

In order to solve the technical problem, the utility model is solved by the following technical scheme: the utility model provides a lightweight wheel hub unit, includes flange ring and flange axle, the epaxial cover that rotates of flange is equipped with the outer lane, the outer lane with be provided with the ball between the flange axle, the outer lane periphery is fixed with the impeller, impeller outside cover is equipped with the sealed cowling, the sealed cowling with the laminating of outer lane is rotated sealedly, the sealed cowling with flange ring fixed connection, be provided with water inlet and delivery port on the sealed cowling both ends face, the water inlet with the delivery port all has the water tank through the pipe connection. This wheel hub unit can be when the car goes, and the outer lane rotates and drives the impeller and rotate, and the automatic power that provides to the flow of cooling water, automatic cycle carries water to cool off the wheel hub unit, slows down wheel hub unit wearing and tearing to prevent that the high temperature from causing the tire spontaneous combustion.

In the above technical scheme, preferably, the water tank is provided with fins, and one side of the water tank is provided with a fan for blowing air to the fins to accelerate heat dissipation. When the automobile runs, the fan accelerates the air flow near the fins, so that the heat dissipation of water in the water tank can be accelerated.

In the above technical scheme, preferably, the outer ring is provided with two annular grooves, and the sealing cover is embedded in the annular grooves and is in rotary sealing with the outer ring. With this structure, the cooling water can be prevented from leaking from the inside of the seal cover.

In the above technical scheme, preferably, the flange ring is provided with a mounting hole, the side surface of the sealing cover is provided with a positioning lug, and the positioning lug is provided with a positioning hole matched with the mounting hole. Adopt this structure can be convenient fixed flange ring and sealed cowling.

Compared with the prior art, the utility model has the following beneficial effects: this wheel hub unit can be when the car goes, and the outer lane rotates and drives the impeller and rotate, and the automatic power that provides to the flow of cooling water, automatic cycle carries water to cool off wheel hub, slows down wheel hub unit wearing and tearing to prevent that the high temperature from causing the tire spontaneous combustion.

Detailed Description

The utility model is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 3, a lightweight wheel hub unit, including flange ring 1 and flange axle 2, it is equipped with outer lane 3 to rotate the cover on the flange axle 2, be provided with ball 4 between outer lane 3 and the

flange axle

2, 3 peripheries in outer lane are fixed with

impeller

5, 5 outside covers of impeller are equipped with sealed cowling 6, sealed cowling 6 rotates sealedly with 3 laminating rotations in outer lane, sealed cowling 6 and flange ring 1 fixed connection, be provided with water inlet 61 and delivery port 62 on the face of 6 both ends of sealed cowling, water inlet 61 and delivery port 62 all have water tank 7 through the pipe connection. This wheel hub unit can be when the car goes, and outer lane 3 rotates and drives impeller 5 and rotate, and is automatic to the flow power that provides of cooling water, and automatic cycle carries water to cool off wheel hub unit, slows down wheel hub unit wearing and tearing to prevent that the high temperature from causing the tire spontaneous combustion.

In this embodiment, the water tank 7 is provided with fins 71, and a fan 72 for blowing air to the fins 71 to accelerate heat dissipation is provided on one side of the water tank 7. When the automobile is running, the fan 72 accelerates the air flow near the fins 71, thereby accelerating the heat dissipation of the water in the water tank 7.

In this embodiment, the outer ring 3 is provided with two annular grooves 31, and the sealing cover 6 is embedded in the annular grooves 31 and is sealed with the outer ring 3 in a rotating manner. With this structure, the cooling water can be prevented from leaking from the inside of the seal cover 6.
