Abstract
The utility model relates to a reformed wheel hub unit comprising a hub assembly. The hub assembly is provided with a step in a shoulder hole, with a bearing arranged in the shoulder hole as well. One end of the bearing leans against the step, and the other end is connected and fixed with the hub assembly. An inside track is provided in the bearing, while a card slot matching with the bearing is opened on the outer wall of the inside track. The utility model has the advantages of that the former hub structure is simplified by replacing the ball bearing with the bearing, which improves the manufacturability of the product; a back-drum typed brake assembly is replaced by a back park disc brake assembly, which provides better stability and improves the integral performance of the vehicle. The new hub unit has the advantages of strong carrying capacity, long service life, simply structure, easy fabrication, low cost and easy popularization, which can be used widely in the back park disc brake assembly of the vehicle.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of hub of remodeling.
Background technology
Present hub mainly is made up of parts such as Hub assembly 1, ball 2, retainer 3, inner ring 4 and hold-down bolts 7, and as shown in Figure 1, wherein Hub assembly 1 effect of outer ring of bearing of having held concurrently is mainly used in the brake system of car.In manufacturing process, since complex structure, the technical requirements height, and manufacture difficulty is relative with cost higher, has caused difficulty for applying of product.In addition, at present the drg of automobile is generally drum-type behind the shroud.Along with the development of production technology, change the back drum brake assembly into brake efficiency high back Parking disk brake assembly, be the development tendency of Automobile manufacturing.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of hub of using the normalisation bearing to replace the remodeling of ball is provided, and has improved the manufacturability of product greatly.
The utility model solves the technical scheme that its technical matters adopts: the hub of this remodeling, comprise Hub assembly, in the stepped hole of described Hub assembly, form a step, being installed in the stepped hole of bearing, the one end is pressed on the step, and the other end and Hub assembly are fixed together; Inner ring is installed in the bearing, has the draw-in groove that matches with bearing on its outer wall.
The effect that the utility model is useful is: this remodeling hub, original hub structure is improved, and simplify original wheel hub structure, adopt bearing to replace ball, improved the manufacturability of product greatly.Substitute former back drum brake assembly with back Parking disk brake assembly, insensitivity is better, has improved the vehicle performance of automobile.This novel hub unit, it is big to have a load-carrying capacity, long service life, simple in structure, easy to manufacture, productive costs is low, and the characteristics that are easy to apply can be widely used in behind the automobile in the Parking disk brake assembly.
Description of drawings
Fig. 1 is that the master of original technology looks cross-sectional view;
Fig. 2 is that master of the present utility model looks cross-sectional view.
Description of reference numerals: Hub assembly 1, step 1-1, stepped hole 1-2, ball 2, retainer 3, inner ring 4, draw-in groove 4-1, bearing 5, the first seal rings 6, hold-down bolt 7, the second seal rings 8, weld nugget 9.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The hub of this remodeling comprises Hub assembly 1, and Hub assembly 1 rear end forms the flange dribbling hold-down bolt 7, directly be connected with automobile rim, and mandrel directly links to each other with constant-velocity universal joint, by female splines driving torque is delivered to wheel.Form a step 1-1 in the stepped hole 1-2 of described Hub assembly 1, bearing 2 is needle bearings and is installed among the stepped hole 1-2 that the one end is pressed on the step 1-1, and the other end and Hub assembly 1 are fixed together by weld nugget 9; Inner ring 4 is installed in the bearing 5, has the draw-in groove 4-1 that matches with the needle roller of bearing 5 on its outer wall.Be respectively equipped with first seal ring 6 and second seal ring 8 between the inwall at described bearing 2 two ends and the inner ring 4.First seal ring 6 and second seal ring 8 are that rubber bodies is attached on the skeleton by the external diameter interference fit of skeleton and inner ring 4, and the inwall interference fit seal by sealing lip and Hub assembly 1.
The utility model patent is compared with typical hub, and it is big to have bearing capacity, long service life, and simple in structure, Easy to manufacture, production cost is low, and the characteristics that are easy to apply have higher economic benefit.
