Description
Technical Field
The utility model relates to a wheel hub unit especially relates to a take wheel hub unit of waterproof construction.
Background
The hub bearing unit is applied to the automobile hub shaft for bearing and providing accurate guide for the rotation of the hub, bears axial load and radial load, and is an important component of automobile load and rotation.
The original structure and the process defects of the product are as follows: the wheel hub bearing unit loading uses under the different complicated operating mode, and the outer lane is assembled on the car, and the rim is connected to the ring flange. The vehicle goes in-process wheel along with the ring flange rotation, and the automobile body is connected to the outer lane, and the rest exposes outside, connects sealing rubber ageing, and inside the rainwater leaked the bearing from outer lane and ring flange junction easily, leaded to the rainwater to permeate the inside risk of bearing more easily, influences life.
Disclosure of Invention
The utility model discloses solve exist not enough among the prior art, provide a take waterproof construction's wheel hub unit who further promotes its performance.
The above technical problem of the present invention can be solved by the following technical solutions:
a hub unit with a waterproof structure comprises a flange plate, wherein an inner ring is embedded at the left end of the flange plate, an outer ring is sleeved outside the inner ring and the flange plate in a hollow manner, retainers are respectively arranged between the inner ring and the flange plate and between the flange plate and the outer ring, steel balls are arranged in the retainers,
the outer wall of outer lane right-hand member be equipped with waterproof interception circle groove, ring flange and outer lane pass through the sealing washer sealed.
Preferably, the inner wall of the waterproof intercepting ring groove is distributed in an arc shape, the left end of the inner wall of the waterproof intercepting ring groove is distributed at an inclination angle of 35 degrees, the right end of the inner wall of the waterproof intercepting ring groove is distributed at an inclination angle of 35 degrees, the distance between the waterproof intercepting ring groove and the edge of the outer ring is 2.5mm, and the thickness of the waterproof intercepting ring groove is 0.6 mm.
Preferably, the flange plate is internally provided with a sealing surface in contact with the sealing ring, the sealing surface is distributed in a circular arc shape, the upper end of the sealing ring and the sealing surface are sealed by an upper waterproof and dustproof lip, the lower end of the sealing ring and the sealing surface are sealed by a lower waterproof and dustproof lip, and the inclination angle of the upper waterproof and dustproof lip seal is larger than that of the lower waterproof and dustproof lip seal.
Preferably, the inner ring and the outer ring are sealed through an outer sealing ring, the outer wall of the outer sealing ring is provided with magnetic rings which are horizontally distributed, and the flange plate is internally provided with an internal spline.
1. These risks are circumvented by the newly designed hub-bearing unit, in which a water-tight interception groove is designed in the outer ring surface. When the vehicle runs into rainwater, the flange plate rotates along with the wheels, rainwater in a rotating area is thrown out, and the rainwater at the static part of the outer ring falls into the waterproof interception groove and is rotationally blocked by the bolt head on the flange plate.
2. Even if residual rainwater seeps to the outer ring and the root of the flange plate, the design of a double waterproof structure is added, the outer sealing lip is waterproof and dustproof, the middle lip is invaded by multiple waterproof and dustproof functions, the matching surface of the sealing part is processed by precision machining, and the sealing effect is more excellent.
The innovative technology mainly overcomes the problem that the product is aged by sealing rubber under the rainwater working condition, so that the rainwater is immersed in the hub bearing, and the phenomenon that the product fails early due to grease pollution caused by rainwater immersion is prevented. Breakthrough of this failure risk is a crucial core technical problem in the industry.
The bolt is connected with the flange plate, the guide surface is connected with the wheel, the internal spline is connected with the transmission shaft (on the vehicle), the inner ring is connected with the flange plate, and the transmission shaft input torque enables the flange plate and the wheel to rotate;
the double sealing ring is connected with the outer ring, the sealing ring is connected with the outer ring, and the magnetic ring is connected with the flange plate and is connected with the vehicle body suspension;
the steel ball retainer rolling body is assembled at the channel of the outer ring and the flange plate to bear axial load and radial load;
because the component rotates along with the wheel, the component is fixed on the body of the vehicle, and the rest parts are exposed outside;
under the extreme rain condition, the rain falls on the outer ring and is intercepted by the watershed of the waterproof intercepting groove, and the splashed rain is thrown off by the centrifugal force of the rotation of the flange plate. Even if residual rainwater seeps to the root of the flange plate, the rainwater is intercepted by a waterproof and dustproof lip; considering the aging of the rubber lip, a double waterproof and dustproof lip is arranged, and the sealing surface of the lip is precisely processed;
the multi-waterproof design can prevent sewage and foreign matters from entering the rolling element of the steel ball retainer in the bearing to cause grease pollution and early internal failure, and effectively prolong the service life of the product.
The technical effects are as follows:
1. the novel design of the product structure increases the waterproof function of the product, reduces the rainwater seepage into the hub bearing, causes grease pollution, abnormal sound of the bearing after impurities are soaked, damages the raceway, early failure of the product and shortened service life of the product;
2. the double waterproof structure of new design, sealed face precision finishing, the sealed double waterproof of design, the foreign matter of outside immersion of dustproof sealing lip interception effectively promote the sealing performance of junction to improve the life of product.
3. The newly developed waterproof groove design and the double-sealing design and the innovation of the process technology make up the risk of waterproof failure.
Therefore, the utility model discloses a take waterproof construction's wheel hub unit, compact structure promotes waterproof ability.
