Abstract

The utility model provides an electronic wheel hub casing of integral type steel sheet drawing belongs to vehicle spare part technical field. It has solved current motor casing both sides and all needs the apron to seal, therefore the equipment is with long problem that manufacturing cost is high. This electronic wheel hub casing of integral type, including wheel hub and the motor casing that is fixed in the wheel hub center, motor casing's lateral wall and bottom surface formula structure as an organic whole are through tensile integrated into one piece, and motor casing's opposite side has the apron through the screw fixation, and cooperation department axial extension with the lateral wall on the apron forms the spacing step of round, and the outer end of lateral wall radially outwards bends and forms the composition face, and the composition face supports with the apron each other and leans on. The utility model has the advantages of short time for assembly and effectively reduced manufacturing cost.

Description

Integrated steel plate stretching electric hub shell

Technical Field

The utility model belongs to the technical field of the vehicle spare part, a wheel hub is related to, electric wheel hub shell is stretched to in particular to integral type steel sheet.

Background

Install driving motor in this kind of generally called electronic wheel hub or wheel hub motor of the holistic structure of wheel hub internal design, electronic wheel hub is because there is not transmission such as gear chain, therefore efficiency is higher for traditional wheel hub, electronic wheel hub shell structure on the present market is split type, pass through the screw fixation and be used for sealed aluminum alloy apron including motor casing and its both sides, because the inside 8mm steel ring that adopts of casing, both sides all need aluminium matter apron to seal, consequently, the product exists heavy, long when the equipment is used, high in manufacturing cost, and along with the electric motor car the popularity is higher and higher application prospect very wide, electronic wheel hub's use amount is also bigger and bigger, do slight reduction in cost and just can produce huge economic benefits.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide an overall structure equipment is more convenient and the tensile electronic wheel hub casing of integral type that low in manufacturing cost.

The purpose of the utility model can be realized by the following technical proposal: electric wheel hub shell is stretched to integral type steel sheet, include wheel hub and the motor casing that is fixed in the wheel hub center, its characterized in that, motor casing's lateral wall and bottom surface formula structure as an organic whole are through tensile integrated into one piece, and motor casing's opposite side has the apron through the screw fixation.

The side cover and the inner ring are connected into a whole through a steel plate stretching technology, the hub and the inner ring are connected through a plurality of inserts, the side wall and the bottom surface are integrally formed through stretching, an original heavy steel ring and an original aluminum cover plate are replaced, and the weight and the material cost of a product are greatly reduced.

In the integrated steel plate stretching electric hub shell, a corresponding bearing seat is coaxially fixed between the bottom surface and the cover plate.

In the integrated steel plate stretching electric hub shell, a circle of limiting step is formed by axially extending the matching part of the cover plate and the side wall.

In the integrated steel plate stretching electric hub shell, the outer end of the side wall is bent outwards in the radial direction to form a joint surface, and the joint surface and the cover plate are abutted against each other.

In the integrated steel plate stretching electric hub shell, the two ends of the outer ring of the side wall are sleeved with the bushings, and the hub, the motor shell and the bushings are fixedly connected through welding.

In the integrated steel plate stretching electric hub shell, a circle of reinforcing ribs are circumferentially arranged on the outer wall of the bottom surface.

Compared with the prior art, this tensile electronic wheel hub casing of integral type steel sheet has following advantage, traditional electronic wheel hub's motor casing is wheel hub middle welding steel ring, the steel ring both sides are passed through the aluminum alloy cover connection, the utility model discloses in a bit, pass through the whole stretch forming of steel sheet about 2mm with one of them apron and motor casing lateral wall, when having reduced weight, material and manufacturing cost have been reduced greatly, the tightness of casing has been increased, also help littleer with wheel hub's tread width design, it is further, support through spacing step and faying face cooperation contact between lateral wall and the apron, make non-deformable behind the motor casing shaping, increase the stability of vehicle driving in-process.
