Description

Technical area

The present invention relates to a wheel assembly, in particular a wheel assembly for low speed vehicles.

State of the art

A wheel assembly for low speed vehicles of the prior art consists of a rim, a hub and spokes. In some bicycle or wheelchair wheel assemblies available on the market, the rim, hub and spokes are integrally formed of the same material. The entire wheel assembly can be made only from a single material and only in one size. If the rim is to have a different size, it is necessary that the entire wheel assembly is reshaped, resulting in a high cost.

Object of the invention

The main object of the present invention is therefore to provide a wheel assembly for low-speed vehicles which can be manufactured at a low cost and is more versatile in its applicability.

Technical solution

To achieve the above object, the present invention employs the technical solution described below.

A low speed vehicle wheel assembly according to the present invention includes a rim, at least three spokes, a plurality of fasteners, a middle bearing seat, and bearings. The outer ends of the spokes are each securely fastened to an inner side wall of the rim by means of the attachment pieces. The inner ends of the spokes are each securely fixed to an outer wall of the middle bearing seat. The bearings are each fitted in corresponding bearing bores on the middle bearing seat.

Preferably, the low speed vehicle wheel assembly includes a guard ring. The guard ring is securely fastened to the inner sidewall of the rim with screws.

Preferably, the middle bearing seat is composed of a center seat and at least three mounting seats. On two sides of the center seat each bearing holes are formed. There may be five attachment seats provided. The at least three, preferably five, mounting seats are fixed at an equal distance from each other on an outer wall of the center seat. The rim has a circumferential inner wall projecting inwardly from a central portion of the inner wall thereof. An outer end of each attachment piece has an engagement groove corresponding to a corresponding spoke and a plurality of transverse bolt holes. The screw holes are connected to the engagement groove. The engagement groove on the outer end of each attachment piece can be mated with the circumferential inner wall on the inner wall of the rim. Screws can be screwed into the screw holes and bolted with nuts to secure the fasteners to a rim. The outer ends of the spokes can be fixed by inserting each at the outer ends of the attachment pieces. The inner ends of the spokes are secured by insertion respectively to the mounting seats of the middle bearing seat.

According to the implementation of the solution described above, the wheel assembly according to the present invention comprises a rim, at least three spokes, a plurality of attachment pieces, a middle bearing seat and a bearing. The rim and middle bearing seat are made as independent components, so they can be made of different materials. Each component can be made and assembled with an independent shape and the diameter of a wheel. The cost of production is thereby lower and the components are more versatile.

Detailed Description of the Preferred Embodiments of the Invention

The 1 and the 2 show a wheel assembly for low-speed vehicles according to a first embodiment of the present invention. This is an embodiment of a wheel assembly in which the wheel is formed with five spokes, the wheel assembly being a rim 1 , five spokes 2 , several attachment pieces 3 , a middle bearing seat 4 , a warehouse 5 and a guard ring 6 includes.

The middle bearing seat 4 is from a middle seat 41 and five attachment seats 42 composed. On both sides of the middle seat 41 is ever a bearing bore 411 intended. The five mounting seats 42 are at an equal distance from each other on an outer wall of the center seat 41 arranged.

The 5 and the 6 show that the rim 1 with a circumferential inner wall 11 is formed by a central part of the inner wall of the rim 1 protrudes. An outer end of each attachment piece 3 has an engagement groove 31 on that with a corresponding spoke 2 and with several transverse bolt holes 32 corresponds. The screw holes 32 are with the engagement groove 31 connected. The engagement groove 31 at the outer end of the attachment piece 3 is suitable for the surrounding inner wall 11 the inner wall of the rim 1 appropriate. Screws 7 are in the screw holes 32 screwed in and bolted with nuts 8 to the attachment pieces 3 on the rim 1 to fix.

The guard ring 6 is safe on the attachment pieces 3 using the screws 7 on the inner wall of the rim 1 attached, attached, so that the guard ring 6 on the outside of the rim 1 is arranged. The outer ends of the spokes 2 are each by insertion at the outer ends of the attachment pieces 3 attached. The inner ends of the spokes 2 are each by inserting on the mounting seats 42 of the middle bearing seat 4 attached. The outer ends of the attachment pieces 3 are secure on the inner sidewall of the rim 1 attached. Camps 5 are each in the bearing bores 411 of the middle bearing seat 4 fitted.

The 3 and the 4 show a wheel assembly for low speed vehicles according to a second embodiment of the present invention, wherein in this embodiment, the wheel is formed with three spokes, wherein the wheel assembly is a rim 1' , three spokes 2 ' , several attachment pieces 3. ' , a middle bearing seat 4 ' , a warehouse 5 ' and a guard ring 6 ' includes. The components of the second embodiment are substantially similar to those of the first embodiment, the exceptions of which are described below. The middle bearing seat 4 ' is from a middle seat 41 ' and from three attachment seats 42 ' composed. The middle bearing seat 4 ' is with three spokes 2 ' safe on the inner sidewall of the rim 1' attached.

The wheel assembly of the present invention is characterized in that the rim, the spokes and the middle bearing seat are formed as independent components.

The above description relates only to preferred embodiments of the present invention, wherein the number of spokes can be set as needed.

In summary, the present invention thus relates to a wheel assembly for low speed vehicles, which is a rim 1 , at least three spokes 2 , several attachment pieces 3 , a middle bearing seat 4 and a warehouse 5 includes. The outer ends of the spokes 2 are each with one of the attachment pieces 3 securely on an inner sidewall of the rim 1 attached. The inner ends of the spokes 2 are safe on an outer wall of the middle bearing seat 4 attached. Camps 5 are each in corresponding bearing bores 411 at the middle bearing seat 4 fitted. Because the rim 1 and the middle bearing seat 4 are independently provided components, each component can be made and assembled with an independent shape and the desired diameter of a wheel. The cost of production is lower and the components are more versatile.

Despite the detailed description of certain embodiments of the present invention for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. The present invention is therefore to be limited only by the scope of the appended claims.
