Abstract
The invention relates to a dune buggy front wheel connecting disk which is provided with an axle hole matched with a knuckle spindle, the axial end of the connecting disk used for connecting with a hub is provided with four threaded studs which are positioned around the axle hole and evenly arranged, and the other axial end thereof is evenly provided with three screwed holes around the axle hole. The dune buggy front wheel connecting disk is characterized in that the axial end surface surrounding axle hole of the connecting disk used for connecting with the hub is provided with a locating lug boss matched with a hub center hole, and the locating lug boss is positioned between the four threaded studs and the axle hole. After the hub and the connecting disk are connected and located, the invention ensures the radial location of the hub is better and the motion of the hub is steadier and does not shift or bounce.
Description
Technical field
The present invention relates to a kind of preceding wheel suspension system of beach buggy, be specifically related to a kind of front wheel connection disc of dune buggy.
Background technology
Beach buggy is the all-terrain baby four-wheel motor cycle, the wheel hub of the front-wheel of beach buggy be by with wheel hub bonded assembly terminal pad and front wheel driving shaft bonded assembly.Owing to be set with four double-screw bolts on the terminal pad, terminal pad inserts simultaneously by these four double-screw bolts and four via holes are set on the wheel hub are fastenedly connected with nut, to insert the via hole of four stationkeeping on the wheel hub simultaneously because of the double-screw bolt of four stationkeeping on the terminal pad, the fit of this while four location, when assembling, be not easy four double-screw bolts and four hole while centerings, formed the location, the difficulty that causes assembling increases, thereby the time all can enlarge the tolerance clearance increase that the aperture makes hole and double-screw bolt in design, and because the increase of the tolerance clearance of hole and double-screw bolt, cause being connected and fixed of wheel hub and terminal pad to be easy to generate radial displacement again, alignment deviation appears, thereby cause beach buggy generation under the vibrations of travelling radially to rock and beat, make the front-wheel of beach buggy have the phenomenon of riding stability reduction, and make wheel hub be diverted the ball head scratch of pull bar easily.
Summary of the invention
The purpose of this invention is to provide a kind of front wheel connection disc of dune buggy, make wheel hub and terminal pad radial location good, wheel hub motion more steadily, be difficult for play or beat.
The object of the present invention is achieved like this: terminal pad is provided with the axis hole that cooperates with steering stub axle, terminal pad be used for be provided with four double-screw bolts with wheel hub bonded assembly axial end, four double-screw bolts are positioned at axis hole uniform setting on every side, around being positioned at axis hole, another axial end of terminal pad is laid with three tapped bore, described terminal pad be used for and wheel hub bonded assembly axial end is provided with around axis hole and is used for the positioning boss that cooperates with the wheel hub circle center hole, this positioning boss is between four double-screw bolts and axis hole.
Owing to adopt technique scheme, the via hole that double-screw bolt on the terminal pad inserts wheel hub is fastenedly connected with nut, terminal pad and wheel hub bonded assembly axial end are provided with and are used for the positioning boss that cooperates with the wheel hub circle center hole, this positioning boss is between four double-screw bolts and axis hole, and the diameter of positioning boss is identical with the diameter of wheel hub circle center hole.Wheel hub is connected one with terminal pad by double-screw bolt like this, and positioning boss inserts the wheel hub circle center hole and forms the location, eliminates the alignment deviation of wheel hub, makes the wheel hub radial location good, is difficult for play; Wheel hub is more steady when motion, and elimination is beated, and guarantees the riding stability of front-wheel; Wheel hub just can not contact with the ball head of steering track rod owing to reduce to rock and beat, and avoids being diverted the ball head scratch of pull bar.In addition, the present invention makes simply, and is convenient and practical.
Description of drawings
Fig. 1 is the scheme drawing of the present invention and wheel hub coupling end;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B of Fig. 2 is to view;
Fig. 4 is the structural representation of existing terminal pad.
In the accompanying drawing, 1 is installation portion, and 2 is double-screw bolt, and 3 is tapped bore, and 4 is positioning boss, and 5 is axis hole, and 6 is oil sealing, and 7 is bearing.
The specific embodiment
Referring to figs. 1 through Fig. 4, terminal pad is provided with the axis hole 5 that cooperates with steering stub axle, is provided with the bearing 7 that supports steering stub axle in the axis hole, and next-door neighbour's bearing is along being provided with oil sealing 6 with wheel hub bonded assembly axial end.Be used for and the wheel hub bonded assembly axial end of described terminal pad 6 is arranged with four installation portions 1 that radially extend, be respectively equipped with double-screw bolt 2 on the installation portion, double-screw bolt 2 on installation portion to wheel hub bonded assembly axial end one side, four double-screw bolts 2 are positioned at uniform setting around the axis hole.Another axial end of terminal pad is provided with three tapped bore 3, and tapped bore 3 is positioned at axis hole uniform setting on every side.Terminal pad and wheel hub bonded assembly axial end are provided with positioning boss 4, described positioning boss 4 circumferentially is provided with around axis hole, positioning boss cooperates with the wheel hub circle center hole, its diameter is identical with the diameter of wheel hub circle center hole, can certainly be slightly less than the wheel hub circle center hole, guarantee that boss cooperates with the wheel hub circle center hole to locate number that this positioning boss is between four double-screw bolts and axis hole, boss between the installation portion is outstanding to the axis hole center, has booster action.
When the present invention was assembled on the wheel hub, double-screw bolt inserted the wheel hub via hole and connects with nut, and boss inserts wheel hub circle center hole location, made wheel hub be difficult for play and beat, and the motion of wheel hub is more steady, avoids wheel hub to be diverted the scratch of drag link ball head.
Claims (2)
1. the front-wheel terminal pad of a four-wheel motor cycle, terminal pad is provided with the axis hole that cooperates with steering stub axle, terminal pad be used for be provided with four double-screw bolts with wheel hub bonded assembly axial end, four double-screw bolts are positioned at axis hole uniform setting on every side, around being positioned at axis hole, another axial end of terminal pad is laid with three tapped bore, it is characterized in that: described terminal pad be used for and wheel hub bonded assembly axial end is provided with around axis hole and is used for the positioning boss that cooperates with the wheel hub circle center hole, the diameter of described diameter that is used for the positioning boss that cooperates with the wheel hub circle center hole and wheel hub circle center hole is identical, and this positioning boss is between four double-screw bolts and axis hole.
2. the front-wheel terminal pad of four-wheel motor cycle according to claim 1 is characterized in that: be used for and the wheel hub bonded assembly axial end of described terminal pad is arranged with four installation portions that radially extend, and four double-screw bolts are separately fixed on four installation portions.
