The utility model discloses profitable effect is: the utility model discloses the structure is through increasing a rolling element in the middle of current automobile wheel hub unit for the wheel hub unit has three rows of rolling elements, then can promote its bearing capacity by a wide margin.

Description

Light non-drive conical hub unit

Technical Field

The utility model relates to a wheel hub unit structure, especially a non-drive circular cone wheel hub unit of lightweight.

Background

The hub bearing is a part applied to an automobile axle for bearing and providing accurate guide for the rotation of a hub, bears axial load and radial load, and is an important component of automobile load and rotation. The hub bearing unit is developed on the basis of a standard angular contact ball bearing and a tapered roller bearing, integrates two sets of bearings, has the advantages of good assembly performance, capability of omitting clearance adjustment, light weight, compact structure, large load capacity, capability of filling lubricating grease in advance for sealing the bearings, capability of omitting external hub sealing, free maintenance and the like, is widely used in cars, and has a tendency of gradually expanding application in trucks. The existing automobile hub bearing unit only has two rows of rolling bodies, so that the bearing capacity of the automobile hub bearing unit is difficult to greatly improve.

Disclosure of Invention

The utility model discloses solve above-mentioned prior art's shortcoming, provide a lightweight non-drive circular cone wheel hub unit that simple structure, bearing capacity are stronger.

The utility model provides a technical scheme that its technical problem adopted: the light-weight non-drive conical hub unit mainly comprises an outer ring, an inner ring and a flange, wherein the outer ring and the inner ring are sleeved on the flange, the inner ring is positioned inside the outer ring, three rolling bodies are arranged between the outer ring and the inner ring, a gear ring is fixed on the inner ring, one end of the outer ring is connected with an end cover, and a sealing ring is arranged at the contact position of the other end of the outer ring and the flange.

The three rolling bodies are a rolling body I, a steel ball and a rolling body II, the steel ball is located between the rolling body I and the rolling body II, and the rolling body I, the steel ball and the rolling body II are fixedly connected with a retainer I, a retainer III and a retainer II sequentially.

The utility model discloses profitable effect is: the utility model discloses the structure is through increasing a rolling element in the middle of current automobile wheel hub unit for the wheel hub unit has three rows of rolling elements, then can promote its bearing capacity by a wide margin.

Drawings

Fig. 1 is a schematic sectional structure diagram of the present invention.

Description of reference numerals: the novel rolling bearing comprises an end cover 1, a gear ring 2, an inner ring 3, a rolling body I4, a retainer I5, an outer ring 6, a retainer III 7, a steel ball 8, a retainer II 9, a rolling body II 10, a sealing ring 11 and a flange 12.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the light-weight non-drive conical hub unit mainly comprises an outer ring 6, an inner ring 3 and a flange 12, the outer ring 6 and the inner ring 3 are sleeved on the flange 12, the inner ring 3 is located inside the outer ring 6, three rolling bodies are arranged between the outer ring 6 and the inner ring 3, the bearing capacity of the hub unit is remarkably improved, the three rolling bodies are rolling bodies I4, steel balls 8 and rolling bodies II 10, the steel balls 8 are located between the rolling bodies I4 and the rolling bodies II 10, the rolling bodies I4, the steel balls 8 and the rolling bodies II 10 sequentially pass through a retainer I5, a retainer III 7 and a retainer II 9 to be fixedly connected, and the rolling bodies are uniformly stressed by. The inner ring 3 is fixed with a gear ring 2, the gear ring 2 is used for providing an ABS signal, one end of the outer ring 6 is connected with an end cover 1, a sealing ring 11 is arranged at the contact position of the other end of the outer ring and a flange 12, and the end cover 1 and the sealing ring 11 play a role in sealing.

The utility model discloses an increase a rolling element in the middle of current automobile wheel hub unit for the wheel hub unit has three rows of rolling elements, then can promote its bearing capacity by a wide margin, and the atress is even moreover, reduces the loss, has promoted the life-span of using.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
