Abstract

The utility model discloses an elastic rim comprising a hub, a plurality of spokes and an axle at the center of the hub. All the spokes are fixed between the inner side of the hub and the axle. The spokes are divided into two alone parts along the radial direction, and the two parts are connected through elastic pieces. In the rim structure, by arranging an elastic structure on the spokes, when a vehicle is knocked by bugles or hard material and the like during a running process, the elastic rim can use the self elasticity to effectively buffer the outside acting force thereby reducing the vibration for a vehicle body and improving the use comfortableness.

Description

The elasticity wheel rim

Technical field

The utility model relates to rim structure, particularly a kind of rim structure with elasticity spoke.

Background technology

For moving body, generally all can wheel be installed in the bottom of car body, traditional wheel is made up of wheel rim and tire, and wheel rim comprises wheel hub and spoke again, tyre ring is placed on the wheel hub, with the ground direct contact,, alleviate vibrations to play buffer action, spoke evenly is fixed in the wheel hub inboard, and intersect at the wheel shaft at center, and utilize the rolling of wheel, reduce to drive the power that car body moves.

The equipment (as wheelchair) of big machinery and some special purposes all uses solid tyre as tire at present, avoid to be moved because of tire punctures, yet, solid tyre is because quality is closely knit, elasticity is relatively poor, deflection is little, when running into hard thing such as stone or projection in the driving process, solid tyre directly is sent to wheel hub with application force, and wheel hub is a rigid construction, application force can be passed to spoke fully, again by the spoke that is similarly rigid construction to wheel shaft, make car body produce strenuous vibration, traveling comfort is very poor, haves much room for improvement.

In view of aforementioned analysis, the design people carries out in-depth study at present widely used rim structure, in the hope of obtaining a kind of rim structure of realizing elastic buffer.

The specific embodiment

Below in conjunction with drawings and the specific embodiments structure of the present utility model and beneficial effect are elaborated.

As Fig. 1 and shown in Figure 6, the utility model provides a kind of elasticity wheel rim, it comprises wheel hub 1, some spokes 2 and wheel shaft 3, described spoke 2 evenly is fixed in the inboard of wheel hub 1 and between the wheel shaft 3 of wheel hub 1 central authorities, and spoke 2 radially is divided into two independent parts, two parts of each spoke 2 all connect by elastic component 21, with the application force of buffering from solid tyre and wheel hub 1.

With reference to shown in Figure 6, be a preferred embodiment of the utility model elasticity wheel rim, elastic component 21 wherein is the foaming materials (can certainly use spring etc.) that utilize curing molding, below introduces detailed making flow process (reference is shown in Figure 1 simultaneously):

(1) make tire forming mold 4 and wheel rim to be processed, described mould 4 comprises the mold 41 and the bed die 42 that can fasten mutually, and the center of mold 41 also offers the plug hole 43 of perforation; This wheel rim to be processed comprises wheel hub 1, is positioned at wheel shaft 3 and some spokes 2 of wheel hub 1 central authorities, this spoke 2 evenly is arranged between wheel hub 1 and the wheel shaft 3, and spoke 2 is a hollow structure, and radially be divided into wheel hub 1 bonded assembly, first end 22 and with wheel shaft 3 bonded assemblys second end 23, the side of wheel shaft 3 offers the through hole 31 that connects and be communicated with the hollow space of spoke 2 second ends 23, and the inboard of wheel hub 1 offers the perforation 11 of perforation to the outside, this perforation 11 also is communicated with the hollow space of spoke 2 first ends 22, can be with reference to shown in Figure 5;

(2) wheel rim to be processed is put into the die cavity of tire forming mold 4;

(3) tire forming mold 4 that closes, and by plug hole 43 pouring foaming material liquid in mould 4, while high speed rotating mould 4, with reference to shown in Figure 2, foaming material liquid is via through hole 31, perforation 11 spaces that are full of between die cavity and the wheel rim to be processed, after the material of waiting to foam solidified, foaming material and wheel rim to be processed were combined closely;
