Abstract
The invention discloses a collocation method of bicycle center shafting loss resistance. Right bearing inner races of a center shaft extends to a near right end of the center shaft; at the right side of a keyboard, and at the position closing to the right side face of the keyboard, the keyboard and the center shaft are arranged into a whole, and are arranged between the two right bearing inner races of the center shaft; a rear fork is manufactured into an H shape; a center shaft sleeve seat is divided into a left part and a right part, namely a left bearing sleeve seat and a right bearing sleeve seat respectively corresponding to the left bearing inner race and the right bearing inner race of the center shaft; and a front fork right support end of an H-shaped rear fork bridge, a lower fork right support end of a front oblique beam and a cylindrical right bearing seat sleeve are connected into a whole, and a front fork left support end of the H-shaped rear fork bridge, a lower fork left support end of the front oblique beam and a cylindrical left bearing seat sleeve are connected into a whole, thus the keyboard is positioned between the two bearings to form a lever mode of single force point-two-side support point.
Description
Technical field
The present invention relates to the centre shaft collocation method of a kind of bicycle or Electrical Bicycle.
Background technology
At present, the centre shaft of known bicycle or Electrical Bicycle configuration is that the axle fit structure places the middle part and chain drum places the system configuration on right side.This configuration mode is ripe and has formed fixing mechanic mode, so that already as the operative norm of quite a lot of maker.Yet, countless bicycles and Electrical Bicycle fault, as axis damage too early, bearing damages too early, too early damage of chain drum, chain-taking, flywheel damage etc., all is related to directly or indirectly this configuration mode.Because the lever pattern in two fulcrums that this configuration mode consists of-one-sided force is so that the backward pulling force of messenger chain almost all acts on the right side fulcrum---right side bearing place, like this, not only cause the stressed dynamics difference in two side bearing places of this configuration excessive, more fatal is stressed opposite direction.On the one hand, the result of wearing and tearing causes axle bowl or the outer ring of two side bearings to extend out round about, and to cause axis to be complied with left front-right backly turn to inclination; On the other hand, the backward pulling force of the right-hand end of messenger chain also causes the slope trend of the front right of chain drum-rear left steering simultaneously.These through constantly vicious circle, finally cause above-mentioned fault.The Electrical Bicycle of longer axis particularly, this situation is more serious.For fundamentally solving these failure problems, must cut off these cause and effect vicious circle chains, and the most thoroughly method of cut-out vicious circle chain changes the axis configuration mode exactly.
Summary of the invention
For root out the center shafting drawback that causes bicycle and Electrical Bicycle fault from the source, the invention provides a kind of bicycle middle shaft is the wear-resistant method.It is by changing the structure of axis-chain drum-crank, back vent and axis cover for seat, and the right side bearing is disposed at the right side of chain drum, so that chain drum is between the two bearings of the left and right sides, consists of the lever pattern of a kind of single force-both sides fulcrum.With this, the backward pulling force of realizing messenger chain in the same way and be close to and act on fifty-fifty both sides fulcrum---the harmonious effect at left and right sides bearing place.
The technical solution adopted for the present invention to solve the technical problems is: the right bearing inner ring of axis is extended down to the nearly right-hand member of axis, and chain drum right side and near chain drum right flank place is namely so that chain drum and axis one and place between the two bearings inner ring of axis; The back vent beam is made " H " shape, two lobes about the axis cover for seat is divided into, i.e. left bearing cover for seat and right bearing cover for seat, the respectively left and right sides bearing inner ring of corresponding axis.The right Zhi Duanyu cylindrical shape of the lower fork right bearing cover for seat of right end of the front fork of " H " shape back vent beam and front cant beam is connected as one; With the left Zhi Duan of lower fork of the left Zhi Duan of front fork of " H " shape back vent beam, front cant beam and the lower end of rear cant beam, connect as one with cylindrical shape left bearing cover for seat.With this, so that chain drum is between the two bearings of the left and right sides, consist of the lever pattern of a kind of single force-both sides fulcrum, the backward pulling force of realizing messenger chain is in the same way and be close to and act on fifty-fifty both sides fulcrum---the harmonious effect at left and right sides bearing place.
The invention has the beneficial effects as follows: fundamentally solved because plurality of bicycles, the Electrical Bicycle failure problems that one-sided chain drum causes, cut off the cause and effect vicious circle chain of these faults, so that the configuration of the centre shaft of bicycle or Electrical Bicycle is prolonged, durable.Whole configuration structure is simple, for convenience detach simultaneously, is easy to transform in existing structure, also is easy to normalisation and batch manufacturing.
