Technical Field

[0001] The utility model relates to the technical field of automobile hub units, in particular to an automobile hub unit with a special-shaped outer ring. Background Art

[0002] Generally speaking, cars basically use traditional automobile hub bearing units. The braking function of the powertrain automatically adjusts the torque on downhill sections to a more appropriate level, reducing brake wear. The main function of the automobile hub unit is to support the wheels, transmit power, provide suspension support, and have monitoring and control functions as well as sealing and protection.

[0003] When existing automobile hub units are in use, a special-shaped outer ring is generally added to the surface. The design of the special-shaped outer ring makes the structure of the hub unit more compact and reduces unnecessary space occupation. A plurality of steel balls are directly arranged between the outer ring and the wheel hub, but the steel balls are easily squeezed during use, resulting in deformation and damage of the steel balls after squeezing, which affects the stability of the hub unit during operation. Utility Model Content

[0004] The purpose of the utility model is to provide an automobile hub unit with a special-shaped outer ring, so as to solve the problem in the above background art that the special-shaped outer ring of the automobile hub is easy to squeeze and deform the steel balls during driving.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the automobile hub unit with a special-shaped outer ring, by arranging the special-shaped outer ring on the surface of the automobile hub unit, can make the structure of the hub unit more compact, reduce unnecessary space occupation, and at the same time have stronger load-bearing capacity and impact resistance, and a cavity is opened inside the special-shaped outer ring body, so that the steel balls arranged between them can have a certain buffer space when they are squeezed, so as to prevent the steel balls from moving to both ends and pushing the limiting ring arranged on one side, so that the limiting ring can squeeze the multiple first springs arranged on one side, and thus can eliminate the generated extrusion force, and at the same time the steel balls can be displaced inside the cavity, which can avoid deformation or damage after being squeezed, so that the automobile hub unit can have a better protection effect on the steel balls after the special-shaped outer ring body is installed.

[0013] 1. The automobile wheel hub unit with a special-shaped outer ring has a cavity formed inside the special-shaped outer ring body, so that the steel balls arranged therebetween have a certain buffer space when they are squeezed. At the same time, the retaining frame provided on one side of the steel balls can prevent them from moving around after being squeezed, thereby preventing the steel balls from moving to both ends. As a result, the steel balls can push the restriction ring after being squeezed, so that the restriction ring can squeeze the first spring after being squeezed, thereby eliminating the generated squeezing force. At the same time, the steel balls can move inside the cavity, which can prevent them from being deformed or damaged after being squeezed. Therefore, the automobile wheel hub unit can provide better protection for the steel balls after the special-shaped outer ring body is installed. At the same time, after the special-shaped outer ring body is installed, the stability and safety of the vehicle under heavy load or complex road conditions are ensured.

[0014] 2. The automobile wheel hub unit with a special-shaped outer ring can be separated from the fixing rod by rotating the bolt, and then the insertion rod can be pulled to drive the second clamping block to separate from the docking rod, and then the protective cover can be pulled to squeeze the first clamping block, so that the protective cover can be quickly removed. Conversely, the protective cover is docked with the docking rod so that the protective cover can squeeze the first clamping block. When the protective cover moves to a certain position, the first clamping block can be locked with the clamping slot through the reset effect of the second spring, and then the insertion rod drives the second clamping block to be inserted into the docking rod so that the second clamping block can be locked with the engaging slot, and then the bolt is rotated to lock it with the fixing rod, so that the protective cover can be quickly installed. At the same time, the protective cover can be prevented from falling directly after the bolt falls off during bumpy driving, so that the automobile wheel hub unit can have better dustproof and anti-falling effects when in use.
