Abstract
The utility model discloses a positioning structure for installing a rear wheel shaft of a motorcycle, which is suitable for dune buggies, and is composed of a rear bridge shell, a rear wheel shaft, a dish-brake disc base, a chain wheel disc base and locking nuts, wherein the dish-brake disc base and the chain wheel disc base are respectively installed on the rear wheel shaft on both sides of the rear bridge shell. Conical needle bearings are installed between the rear bridge shell and the rear wheel shaft and are installed on positioning steps on both sides of the rear bridge shell, and in addition, the left side of the rear wheel shaft is provided with a positioning step which is just butted with the outer end of the conical needle bearing on the left side so that the rear wheel shaft is axially positioned; the right side of the dish-brake disc base is provided with two locking nuts. Because the utility model makes use of the conical needle bearings in the rear bridge shell and the positioning steps on both of the two sides to position, and because the rear wheel shaft is axially positioned in the rear bridge shell through the dish-brake disc base by the locking nuts on the right side, the utility model has the advantages of simple installation and convenient maintenance. In addition, a liner tube is canceled so that the utility model avoids the generation of impact and noise between the liner tube and the rear wheel shaft.
Description
Technical field
The utility model belongs to the drive axle technology of motor bike, is specifically related to a kind of motorcycle rear axle installation and positioning structure, is specially adapted to use on beach buggy.
Background technology
The detent mechanism of existing beach buggy hind axle mainly contains bushing pipe, rear-axle casing, disc brake seat, chain sprocket seat, left terminal pad, right terminal pad composition.Rear-axle casing is contained between chain sprocket seat and the disc brake seat.Wherein respectively there is a bearing at the rear-axle casing two ends, the bushing pipe location in this Bearing support rear-axle casing.Between left terminal pad and chain sprocket seat and between right terminal pad and disc brake seat, be added with a bushing pipe respectively.The defective that this structure exists is: 1, can not carry out axial location to hind axle, when tightening the hind axle nut, can cause that hind axle moves axially, to the hind axle nut inconvenience installation that makes the other end, maintenance difficult.2, bushing pipe is contained on the hind axle, and in the beach buggy driving process, bushing pipe is understood mutual friction mutually with hind axle and produced noise simultaneously.
Summary of the invention
The utility model is at the prior art above shortcomings, and purpose is to provide a kind of motorcycle rear axle installation and positioning structure, so that hind axle is carried out axial location, makes the easy for installation simple of hind axle, reduces friction and noise.
To achieve these goals, keystone configuration of the present utility model is made up of rear-axle casing, hind axle, disc brake seat, chain sprocket seat, jam nut.Rear-axle casing is installed on the hind axle, disc brake seat and chain sprocket seat are installed respectively on the hind axle of rear-axle casing both sides.The circular cone needle bearing is installed between described rear-axle casing and the hind axle, this circular cone needle bearing is installed on the positioning step of both sides in the rear-axle casing, be processed with a location step in addition in the left side of hind axle, just in time the outer end with left side circular cone needle bearing offsets, the circular cone needle bearing is positioned and is installed in like this, and hind axle is carried out axial location; Described disc brake seat the right is equipped with two jam nuts.
The utility model is owing to utilize the positioning step in step in the rear-axle casing, circular cone needle bearing and hind axle left side that hind axle has been carried out axial location accurately, hind axle can only be rotated and can not move axially, utilize jam nut that disc brake seat is fixed on the hind axle simultaneously, it is simple, easy to maintenance that it is installed; On the other hand, also cancel bushing pipe, can avoid collision and noise generation between bushing pipe and the hind axle.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model;
Fig. 2 is an I portion enlarged drawing.
The specific embodiment
Describe structure of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this structure is by hind axle 1, chain sprocket seat 2, and rear-axle casing 3, disc brake seat 4, jam nut 5, circular cone needle bearing 6 constitutes.In rear-axle casing 3, on positioning step A, the B of both sides a circular cone needle bearing 6 is installed respectively earlier, rear-axle casing 3 is installed on the hind axle 1, the outer end of left side circular cone needle bearing 6 is leaned against on the positioning step C on hind axle 1 left side, then chain sprocket seat 2 is installed on the spline on hind axle 1 left side, (being rear-axle casing 3 right sides) loads onto disc brake seat 2 on hind axle 1 the right again, two jam nuts 5 of screwing at last, i.e. assembling obtains the utility model structure.
