Abstract

The utility model discloses an improved two-piece hub, which comprises a rim, a spoke and a plurality of connecting bolts, wherein the connecting bolts are uniformly distributed along the circumference of the spoke to connect the spoke to the rim; the spoke comprises a spoke surface, the outer end of the spoke surface is provided with a connecting step ring, and the step of the connecting step ring is attached to the step formed by the fixed bottom ring and the connecting ring; the outer end of spoke still extends one to the rim center and pastes the connection foundation ring with the go-between lower surface mutually, and connecting bolt pierces through with the mode of the axis of vertical direction rim and connects the foundation ring and be connected to the go-between, this practicality compares traditional structure, changes screw installation direction, and the atress is not crooked, and the strip width of installation is firm more durable than traditional two formula wheel hub moreover.

Description

Improved two-piece hub

Technical Field

The utility model relates to the field of hub manufacturing, in particular to an improved two-piece hub.

Background

Two piece formula wheel hub means that the rim is one, and the spoke is one, and is connected integratively through the bolt between, and traditional connection structure adds the narrow strip of round in the rim inner wall, with the screw about pierce through the spoke and be connected to on the strip, but the strip is through not playing the atress, and the improvement scheme commonly used is to widen the strip, leads to the screw extension, and the screw rigidity of extension is not enough, and easy atress is crooked, the dismantlement in later stage of not being convenient for.

In view of the above, the present inventors provide an improved two-piece hub.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides an improved two-piece hub, which solves the defects.

In order to solve the technical problem, the utility model adopts the following technical scheme:

an improved two-piece hub comprises a rim, a spoke and a plurality of connecting bolts, wherein the connecting bolts are uniformly distributed along the circumference of the spoke to connect the spoke to the rim, the rim comprises a cylinder ring, a fixed bottom ring is welded on the inner wall of the cylinder ring, a connecting ring is arranged on the inner wall of the fixed bottom ring, and the width of the fixed bottom ring is larger than that of the connecting ring to form a circular step;

the spoke comprises a spoke surface, the outer end of the spoke surface is provided with a connecting step ring, and the step of the connecting step ring is attached to the step formed by the fixed bottom ring and the connecting ring;

the outer end of the spoke surface also extends towards the center of the wheel rim to form a connecting bottom ring attached to the lower surface of the connecting ring, and the connecting bolt penetrates through the connecting bottom ring to be connected to the connecting ring in a mode of being vertically directed to the axis of the wheel rim.

Further, the connecting ring and the fixed bottom ring are integrally arranged.

Furthermore, the connecting rings are a plurality of unconnected segments, and the segments are arranged on a circle.

The utility model has the beneficial effects that:

compare traditional structure, change screw installation direction, the atress is not crooked, and the wide big knot of strip of installation moreover is more durable than traditional two formula wheel hub.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides an improved two-piece wheel hub, including a rim 1, a spoke 2 and a plurality of connecting bolts 3, where the rim 1 includes a cylinder ring 1a, a fixed bottom ring 1b is welded to an inner wall of the cylinder ring 1a, an inner wall of the fixed bottom ring 1b is provided with a connecting ring 1c, and a width of the fixed bottom ring 1b is greater than a width of the connecting ring 1c to form a circular step; in order to secure strength, the connection ring 1c is integrally provided with the stationary base ring 1 b.

The spoke 2 comprises a spoke surface 2a, the outer end of the spoke surface 2a is provided with a connecting step ring 2b, and the step of the connecting step ring 2b is attached to the step formed by the fixed bottom ring 1b and the connecting ring 1 c;

the outer ends of the spokes 2a extend towards the center of the rim 1 to form a connecting bottom ring 2c attached to the lower surface of the connecting ring 1c, the connecting bolts 3 penetrate through the connecting bottom ring 2c in a mode of being vertically directed to the axis of the rim 1 to be connected to the connecting ring 1c, compared with the traditional structure, the hub changes the mounting direction of screws, is not bent under stress, and is more firm and durable in mounting strip width than the traditional two-piece hub.

Referring to fig. 4, the connecting ring 1c is formed by several non-connected segments, and the segments are located on a circle, so that the weight of the connecting ring is reduced and the strength is not affected.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
