Abstract
The utility model discloses a disc brake quick-disassembling type hub which comprises a hollow mandrel and a hub shell arranged outside the hollow mandrel, the two ends of the hollow mandrel extend out of the hub shell, the hollow mandrel sequentially comprises a first outer threaded portion, a first bearing portion, an unthreaded hole portion, a second bearing portion and a second outer threaded portion, a quick-disassembling pull rod hole is formed in the hollow mandrel, a disc brake connecting disc is arranged at the front end of the hub shell in an integrated mode, and a disc brake connecting hole is formed in the disc brake connecting disc; a long bush is arranged on the hollow pull rod. The disc brake quick-disassembling type hub has the advantages that due to the fact that the brake disc connecting disc is arranged on the hub shell and the exposed hollow mandrel is sleeved with the bush, the length of exposed part of the hollow mandrel is reduced, the hollow mandrel is more bending-resistant, and the quick-disassembling pull rod hole can be formed in the hollow mandrel, and quick-disassembling pulling efficiency is improved.
Description
Technical field
The utility model relates to a kind of bicycle hub.
Background technology
Bicycle hub is for making axle for bicycle and wheel hub parts in relative rotation, generally comprise mandrel and be enclosed within the outer axle cot of mandrel, the axle cot is provided with front spoke seat and rear spoke seat, thereby connect cycle hub for connecting spoke, but some width of existing wheel hub is very little, thereby between front spoke seat and rear spoke seat, spacing is very little, and the width of vehicle crotch does not change, so relatively and the axle cot we need to lengthen a little mandrel, after but mandrel lengthens, intensity weakens to some extent, particularly adopts now the mandrel of quick-disassembly structure, intensity more a little less than.
Summary of the invention
In order to overcome the existing low deficiency of bicycle hub intensity, the utility model provides the disc brake fast disassembly type axle skin that a kind of intensity is high.
The technical scheme in the invention for solving the technical problem is: a kind of disc brake fast disassembly type axle skin, comprise a hollow core shaft and be enclosed within the outer axle cot of hollow core shaft, described axle cot is provided with front spoke seat and rear spoke seat, described hollow core shaft two ends stretch out in the axle cot, described hollow core shaft is respectively the first external thread part, clutch shaft bearing section, unthreaded hole section, the second bearing portion, the second external thread part, described unthreaded hole section diameter is greater than clutch shaft bearing section and the second bearing portion and is forming first step with clutch shaft bearing section intersection, forming second step with the second bearing portion intersection, be provided with the quick detach tie rod hole in described hollow core shaft, described axle cot front end is the integrated disc brake terminal pad that is provided with also, and described disc brake terminal pad is provided with the disc brake connecting bore, on described the first external thread part, spiral shell is provided with a pair of the first nut, be arranged with clutch shaft bearing in described clutch shaft bearing section and described clutch shaft bearing is positioned at disc brake terminal pad inboard, described the first nut and first step are clamped the inner ring of described clutch shaft bearing, be provided with the first top shoulder in described axle cot, described the first top shoulder is withstood in the outer ring of clutch shaft bearing, on described the second external thread part from front to back spiral shell be provided with a pair of the second nut, the described hollow core shaft of described the second nut front end is arranged with long bushing outward, be arranged with the second bearing on described the second bearing portion, the length of described the second bearing portion is greater than described the second bearing, and described long bushing and second step are clamped the inner ring of the second bearing, be provided with the second top shoulder in described axle cot, described the second top shoulder is withstood in the outer ring of the second bearing.
Thereby described the first nut and the second nut have two can the self-locking fixed position, on described front spoke seat and rear spoke seat in order to spoke to be installed.Disc brake terminal pad and axle skin are set together, and make to a certain extent exposed mandrel length reduce, and make mandrel be not easy distortion, thereby make in mandrel, the quick detach tie rod hole can be set smoothly,
The utility model is consistent with the fast disassembly type bicycle hub of existing technology in use, the disc brake wheel is set on the disc brake terminal pad, pass quick detach in the quick detach tie rod hole of hollow core shaft, crotch is placed between quick detach two ends and the first nut, the second nut, pull quick detach, draw lever locking drives two ends quick detach crotch is fixed on hollow core shaft.
The beneficial effects of the utility model are: the disc brake terminal pad is set on the axle skin, thereby sheathed lining makes exposed hollow core shaft length reduce outside exposed hollow core shaft, thereby make hollow core shaft bending resistance more, can in offer the quick detach tie rod hole, improve quick detach and pull efficiency.
The accompanying drawing explanation
Fig. 1 be embodiment of the utility model partly cut open schematic diagram.
Fig. 2 is A place partial enlarged drawing in Fig. 1.
Fig. 3 is B place partial enlarged drawing in Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
By reference to the accompanying drawings 1 to 3, a kind of disc brake fast disassembly type axle skin, comprise a hollow core shaft 1 and be enclosed within the outer axle cot 2 of hollow core shaft 1, described axle cot 2 is provided with front spoke seat 3 and rear spoke seat 4, described hollow core shaft 1 two ends stretch out in axle cot 2, described hollow core shaft 1 is respectively the first external thread part 5, clutch shaft bearing section 6, unthreaded hole section 7, the second bearing portion 8, the second external thread part 9, described unthreaded hole section 7 diameters are greater than clutch shaft bearing section 6 and the second bearing portion 8 and are forming first steps 10 with clutch shaft bearing section 6 intersections, forming second step 11 with the second bearing portion 8 intersections, be provided with quick detach tie rod hole 12 in described hollow core shaft 1, described axle cot 2 front ends are the integrated disc brake terminal pad 13 that is provided with also, and described disc brake terminal pad 13 is provided with disc brake connecting bore 14, on described the first external thread part 5 from front to back spiral shell be provided with a pair of the first nut 15, be arranged with clutch shaft bearing 16 in described clutch shaft bearing section and described clutch shaft bearing 16 is positioned at disc brake terminal pad 13 inboards, described the first nut 15 and first step 10 are clamped the inner ring of described clutch shaft bearing 16, be provided with the first top shoulder 17 in described axle cot, described the first top shoulder 17 is withstood in the outer ring of clutch shaft bearing 16, on described the second external thread part, spiral shell is provided with a pair of the second nut 18, the described hollow core shaft of described the second nut 18 front end is arranged with long bushing 19 outward, be arranged with the second bearing 20 on described the second bearing portion, the length of described the second bearing portion 8 is greater than described the second bearing 20, and described long bushing 19 and second step 11 are clamped the inner ring of the second bearing 20, described the second top shoulder 21 is withstood in the outer ring that is provided with the second top shoulder 21, the second bearings in described axle cot.
