The utility model discloses can prevent the flywheel beat.
Description
Technical field
This utility model is related to a kind of bicycle drive shaft, the flower-drum of more particularly, to a kind of anti-beat.
Background technology
The at present multi-speed flywheel in bicycle trade, especially 7 fast following flywheels are all rotating flywheels, this rotating flywheel with
Flower-drum is threaded.Due to low with the accuracy of screw machining of flower-drum junction and screw thread is easy to wear during rotating flywheel turns, therefore
After long-time use, rotating flywheel usually can occur beat, and affect to ride effect.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bicycle drive shaft, can in case
Only flywheel beat.
The purpose of this utility model employs the following technical solutions realization：
A kind of bicycle drive shaft, including flower-drum body and mandrel, this flower-drum body has and is sheathed on this external shell of flower-drum
Body and the flower-drum disk being removably fixed on shell one end, are provided with bearing, the outer wall of flower-drum disk between flower-drum disk and mandrel
It is provided with the ring shaped thread connecting portion for being connected with flywheel, flower-drum disk is provided with the locking for locking flywheel away from the sidepiece of housing
Nut, fixes finite place piece in ring shaped thread connecting portion away from the sidepiece of locking nut, and this locating part is used for abutting with flywheel.
Preferably, a kind of locating part of above-mentioned bicycle drive shaft includes multiple projections, and this projection is along flower-drum disk outer wall week
To interval setting.
Preferably, a kind of locating part of above-mentioned bicycle drive shaft is metal washer.
Compared to existing technology, the beneficial effects of the utility model are：
This utility model passes through to arrange locating part in the outer wall of flower-drum disk, and it is remote to make locating part be located at ring shaped thread connecting portion
From the sidepiece of locking nut, for abutting with flywheel, so, can make to be arranged on ring shaped thread connecting portion of the present utility model
Flywheel will not be towards casing center beat, so that the effect of riding with bicycle of the present utility model is good in operation process
Good, and lift Consumer's Experience.

Specific embodiment
Below, in conjunction with accompanying drawing and specific embodiment, this utility model is described further：
Refer to Fig. 1 and Fig. 2, a kind of bicycle drive shaft, including flower-drum body and mandrel 3, this flower-drum body has sheathed
This external housing 1 and the flower-drum disk 2 being removably fixed on housing 1 one end in flower-drum, between flower-drum disk 2 and mandrel 3
It is provided with bearing, the outer wall of flower-drum disk 2 is provided with the ring shaped thread connecting portion 21 for being connected with flywheel 6, and flower-drum disk 2 is away from housing 1
Sidepiece be provided with locking nut 4 for locking flywheel 6, fix away from the sidepiece of locking nut 4 in ring shaped thread connecting portion 21
Finite place piece, this locating part is used for abutting with flywheel 6.
This bicycle drive shaft use when, due to being provided with locking nut 4 in flower-drum disk 2 away from the sidepiece of housing 1, therefore when
Flywheel 6 is connected with ring shaped thread connecting portion 21 with thread connecting mode and is fixed on after flower-drum disk 2 outer wall, locking nut 4 can
To prevent flywheel 6 from screwing out towards the end away from housing 1 due to centrifugal action in operation process, and it is fixed on ring shaped thread
The locating part of the sidepiece away from locking nut 4 for the connecting portion 21 can form good abutting when flywheel 6 occurs beat to it, with
Prevent flywheel 6 in operation process because the accuracy of thread of ring shaped thread connecting portion 21 not or thread abrasion and lead to flywheel 6 court
Near the beat of housing 1, so that it is respond well to have riding of the bicycle of this bicycle drive shaft, improve Consumer's Experience.
For material-saving, the locating part in the present embodiment includes multiple raised 5, this projection 5 along housing 1 outer wall circumference between
Every setting, so, raised 5 can occur the position of beat to be formed to hinder to flywheel 6, and multiple raised 5 circumferentially disposed permissible
Ensure that different parts beat occurring to flywheel 6 all can form obstruction, thus ensureing using effect.Projection in the present embodiment
5 can be widened according to specific needs, be lengthened or thickened process.Of course for the bulk strength strengthening locating part, acceptable
Locating part is set to metal washer.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim
Within the scope of.
