CN201366902Y - Air charging-free shock absorbing bicycle wheel - Google Patents

Abstract

The utility model discloses an air charging-free shock absorbing bicycle wheel which relates to improvement on bicycle wheel structure and consists of a wheel rim, a fixing ring, spokes, a shaft sleeve, a plurality of supporting bars and supporting springs. The air charging-free shock absorbing bicycle wheel is characterized in that the external wall of the wheel rim is sheathed with a solid rubber ring; the internal wall thereof is connected with the fixing ring through the spokes; the wall of the fixing ring is uniformly provided with a plurality of rectangular through holes; a sleeve is rotatably connected in the through hole; a plurality of supporting bars are uniformly and rotatably connected around the middle part of the external wall of the shaft sleeve; the upper end of the supporting bar penetrates the sleeve with the inner diameter matched the outer diameter of the supporting bar and then is connected with a limited block; and the supporting spring is sheathed on the supporting bar between the limited block and the external wall of the fixing ring. The air charging-free shock absorbing bicycle wheel has the advantages that as the external part of the wheel rim is only sheathed with the solid rubber ring without need of an inner tire, the air charging-free shock absorbing bicycle wheel does not need to be charged, can avoid being punctured, has good shock absorbing effect, is not easily deformed and has long service life.

Description

The inflation-free shock-absorbing wheel

Technical field

The utility model relates to a kind of improvement of cycle wheel structure, specifically a kind of inflation-free shock-absorbing wheel of bicycle use.

Background technology

At present, traditional cycle wheel mainly is made up of cover tire, the inner tube of a tyre, rim, spoke, nave boss, and this kind wheel needs often to inflate to the inner tube of a tyre when concrete the use, and to guarantee the normal use of bicycle, if the inner tube of a tyre is pricked, bicycle just can't use; And this wheel damping performance is poor, easily causes the distortion of rim and spoke, uses birthday noodle short.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of damping performance is good, the on-deformable inflation-free shock-absorbing wheel of wheel.

Order of the present utility model is achieved in that this inflation-free shock-absorbing wheel is made up of rim, set collar, spoke, axle sleeve, strut bar, support spring, the rim outer wall is with the solid rubber circle, inwall links to each other with set collar by spoke, be provided with a plurality of rectangular through holes on the set collar ring wall equably, sleeve is being rotationally connected in the through hole; A plurality of strut bars that are being rotationally connected equably around the axle sleeve outer wall middle part, post upper link to each other with limiting stopper after passing internal diameter and sleeve that the strut bar external diameter adapts, are with support spring on the strut bar between limiting stopper and the set collar outer wall.

Advantage of the present utility model: because the rim outside only overlaps the solid rubber circle and need not use the inner tube of a tyre, thereby need not inflate, be not afraid of the bundle tire yet, and have good damping performance, wheel is not yielding, long service life.

Accompanying drawing is a structure cutaway view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail: this inflation-free shock-absorbing wheel is made up of rim 1, set collar 2, spoke 3, axle sleeve 4, strut bar 5, support spring 6, rim 1 outer wall is with solid rubber circle 7, inwall links to each other with set collar 2 by spoke 3, be provided with a plurality of rectangular through holes 8 on set collar 2 ring walls equably, sleeve 9 is being rotationally connected in the through hole 8; A plurality of strut bars 5 equably are being rotationally connected around the axle sleeve 4 outer walls middle part, strut bar 5 upper ends are passed internal diameter and are linked to each other with limiting stopper 10 with sleeve 9 backs that strut bar 5 external diameters adapt, and are with support spring 6 on the strut bar 5 between limiting stopper 10 and set collar 2 outer walls.

Claims (1)

1, a kind of inflation-free shock-absorbing wheel, form by rim (1), set collar (2), spoke (3), axle sleeve (4), strut bar (5), support spring (6), it is characterized in that rim (1) outer wall is with solid rubber circle (7), inwall links to each other with set collar (2) by spoke (3), be provided with a plurality of rectangular through holes (8) equably on set collar (2) ring wall, sleeve (9) is being rotationally connected in the through hole (8); A plurality of strut bars (5) equably are being rotationally connected around axle sleeve (4) the outer wall middle part, strut bar (5) upper end is passed internal diameter and is linked to each other with limiting stopper (10) with sleeve (9) back that strut bar (5) external diameter adapts, and is with support spring (6) on the strut bar (5) between limiting stopper (10) and set collar (2) outer wall.
