The utility model provides a hub bearing unit with a light flange, which is provided with a first weight reduction groove, a second weight reduction groove and a third weight reduction groove, so that the weight of a flange plate can be reduced by more than 30%.

Description

Hub bearing unit with light flange

Technical Field

The utility model relates to the field of automobile parts, in particular to a hub bearing unit with a lightweight flange.

Background

Under the influence of carbon dioxide emission control and oil price rising, energy conservation and emission reduction of automobiles become urgent. The countermeasure is to reduce the weight of the chassis components of the vehicle. Hub bearing units are the main components of the chassis of the vehicle, so how to lightweight the design is also the main trend in research and development.

Disclosure of utility model

In order to overcome the defects of the background technology, the utility model provides a hub bearing unit with a light flange, which mainly solves the problem that the flange plate of the existing hub bearing unit is heavy.

The technical scheme adopted by the utility model is as follows:

The flange light hub bearing unit comprises a flange plate and an outer ring, wherein the flange plate comprises a chassis, a flange shaft is arranged in the center of the chassis, at least three reinforcing ribs are arranged on the chassis, one ends of the reinforcing ribs are connected with the flange shaft, and a first weight reduction groove is formed between every two adjacent reinforcing ribs;

at least one reinforcing rib is provided with a second weight reducing groove which is concavely arranged;

The flange shaft is used for being provided with a plurality of third weight reduction grooves with one end of the rim guide.

The number of the reinforcing ribs is 5.

The spacing angle between the reinforcing ribs is the same.

And the second weight reducing grooves are formed in the reinforcing ribs.

And mounting holes for mounting screws are formed in the reinforcing ribs.

The chassis comprises end parts, the number of which is the same as that of the reinforcing ribs, and the end parts are connected through concave arc-shaped surfaces.

And three third weight reducing grooves are formed.

The beneficial effects of the utility model are as follows: the utility model provides a hub bearing unit with a light flange, which is provided with a first weight reduction groove, a second weight reduction groove and a third weight reduction groove, so that the weight of a flange plate can be reduced by more than 30%.

Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the hub bearing unit with the light flange comprises a flange plate 91 and an outer ring 92, wherein the flange plate comprises a chassis 1, a flange shaft 2 is arranged in the center of the chassis, at least three reinforcing ribs 3 are arranged on the chassis, one ends of the reinforcing ribs are connected with the flange shaft, and a first weight reduction groove 31 is arranged between every two adjacent reinforcing ribs; at least one of the reinforcing ribs is provided with a second weight-reducing groove 32 which is concavely arranged; the flange shaft is used for being provided with a plurality of third weight reduction grooves 21 at one end of the flange shaft, which is used for guiding the rim. The conventional flange plate is characterized in that the chassis is used as a reference to directly stretch the reinforcing ribs in a full area, so that the weight is heavy; on the basis of the above, the flange shaft is provided with the third weight reduction groove at one end which is opposite to the rim, so that the weight of the flange shaft can be reduced to a certain extent, in sum, the weight of the flange plate can be reduced by more than 30% by arranging the weight reduction groove, the requirement of rigidity of a product is met, and the dynamic bending test is more than or equal to 100 ten thousand times.

In this embodiment, as shown in the figure, 5 reinforcing ribs are provided. The weight can be reduced without affecting the mechanical requirements.

In this embodiment, as shown in the drawing, the spacing angle between the reinforcing ribs is the same. Can be stressed more uniformly.

In this embodiment, as shown in the drawing, each of the reinforcing ribs is provided with the second weight-reducing groove. The weight can be reduced even better.

In this embodiment, as shown in the drawing, each of the reinforcing ribs is provided with a mounting hole 33 for screw mounting. The chassis is also provided with the mounting holes communicated with the mounting holes, so that a larger mounting area is provided when the screws are mounted, and the mounting is more stable.

In this embodiment, as shown in the figure, the chassis includes the same number of end portions 11 as the reinforcing ribs, and each of the end portions is connected by a concave arc surface 111. The conventional chassis is round with each end part as a point, and the application cuts off a part of the round and connects each end part by an arc surface, so that the weight can be further reduced.

In this embodiment, as shown in the drawing, three third weight-reducing grooves are provided.

In the description of the present utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.
