Abstract

The utility model relates to a hard tyre bicycle, which is characterized in that the tyre of the bicycle is a solid hard tyre. The upper pipe and the upright branch of the known bicycle are replaced by an arc pipe, the pipe of a saddle passes through the arc pipe and is fixed on a flat branch through a vibration absorber, and the wheel shaft of the bicycle is provided with a suspension device. The utility model has the advantages that the users have no need to charge air, the tyre is not afraid of sticking, and the bump-proof ability is ensured by the vibration absorber and the suspension device.

Description

Hard tire bicycle

The utility model relates to bicycle, and particularly (B62K, B62J, B60C) is relevant with tire for vehicles, saddle, axle suspension device.

Public bicycle is an air-inflation tyre, and its advantage is the shock-absorbing better performances, is lost heart but stab easily, especially in the open air, can repair nowhere.

Task of the present utility model provide a kind of needn't gas filed hard tire bicycle, there is not disappointing disadvantage in it, can keep shock-absorbing performance preferably again.

Task realizes by following scheme:

Hard tire bicycle has front-wheel, trailing wheel at least and has the vehicle frame of arc pipe, it is characterized in that having on the rim solid hard tire, between saddle and the chain stay shock absorber is arranged, and suspension gear is housed on the wheel shaft.

By the model machine that such scheme is made, kept shock-absorbing performance preferably, have the advantage of exempting to inflate, be not afraid of stamp.

Accompanying drawing is the scheme drawing of an embodiment of the present utility model.

Below in conjunction with accompanying drawing, this embodiment is described.

Hard tire bicycle has the vehicle frame of front-wheel [2], trailing wheel [8] and band arc pipe [3] at least.Arc pipe [3] begins from preceding pipe, divides two until hind axle, i.e. two cooresponding arc pipes of radian [3], pipe beginning in the past simultaneously, pass through the two ends of the cross-arm of standpipe [4] upper end separately, and saddle [7] stationary pipes is clipped in the middle, arrive the two ends (this structure is a known technology) of hind axle then.It can replace going up pipe and founding fork in the another kind of known bicycle.Standpipe [4] is fixed between arc pipe [3] stage casing and the axis.Saddle [7] links to each other with chain stay [5] by shock absorber [6].This routine shock absorber [6] is made of the attic base at spring and two ends thereof.

Tire [1] is solid hard tire, can make breach [1a] with the female contact position of spoke bar.This hard tire can be pulled on the rim by force with crowbar.

Said wheel shaft suspension gear is axle sleeve [9a] in the scheme, spring [9b], and floral disc tube [9c] structure promptly on the known axle that has steel ball, axle bowl, an axle bumper, adds cover one axle sleeve [9a], and its two ends are connected with two axle bowls.The seat hole that more spring [9b] is arranged on the outer cylinder of axle sleeve.These springs [9b] are the center of circle with the wheel shaft, radially distribute, and its outer end links to each other with floral disc tube [9c] corresponding seats.

Claims

1, hard tire bicycle have front-wheel [2], trailing wheel [8] at least and have arc pipe [3] vehicle frame, it is characterized in that:

Solid hard tire [1] is arranged on A, the rim; With

Between B, saddle [7] and the chain stay [5] shock absorber [6] is arranged; With

Suspension gear [9] is housed on C, the wheel shaft.

2,, it is characterized in that the attic base structure of shock absorber [6] for spring and two ends thereof as the said hard tire bicycle of claim 1.

3, as claim 1 or 2 said hard tire bicycles, the suspension gear [9] that it is characterized in that wheel shaft is axle sleeve [9a], spring [9b], floral disc tube [9c] structure, be that axle sleeve [9a] two ends link to each other with two axle bowls, have the more seat hole that holds spring [9b] on its outer cylinder; Spring [9b] is the center of circle with the axle, radially distributes, and its outer end is gone up corresponding spring base hole with floral disc tube [9c] separately and linked to each other.
