Abstract
The utility model relates to a rear wheel axle assembly of a beach vehicle, comprising a rear wheel axle, a rear axle body, a brake disc and a chain wheel disc. The rear axle body is supported at the middle part of the rear wheel axle by a bearing, the brake disc and the chain wheel disc are respectively fixed on a brake disc seat and a chain wheel disc seat, the brake disc seat and the chain wheel disc seat are respectively arranged at the two sides of the rear axle body and are connected with the rear wheel axle in a spline manner, the outer side of one of the brake disc seat and the chain wheel disc seat is axially positioned by a double nut, and the outer side of the other one of the brake disc seat and the chain wheel disc seat is axially positioned by a clamp spring. By adopting the technical scheme of the rear wheel axle assembly, parts such as the rear axle body on the rear wheel axle, the disc seats and the like can realize reliable axial positioning; moreover, the rear wheel axle assembly has the characteristics of simple structure, convenient assembling/disassembling and low cost.
Description
Technical field
The utility model relates to the assembly unit on the beach buggy, especially rear axle shaft assembly of dune buggy.
Background technology
At present, common chain-driving rear axle shaft assembly of dune buggy mainly is made up of hind axle, back pontic, disc brake dish and chain sprocket, disc brake dish, chain sprocket are separately fixed on disc brake seat, the chain sprocket seat, are spline between disc brake seat, chain sprocket seat and the hind axle and are connected; Back pontic is by the middle part of bearings at hind axle, and disc brake seat and chain sprocket seat axial location are on hind axle and lay respectively at the both sides of back pontic.Pontic is connected with the chain stay rear end after during the car load assembling, and chain sprocket links to each other with the mouth sprocket wheel of driving engine by chain, and the disc brake dish matches with the brake clamp of brake system.On existing rear axle shaft assembly of dune buggy, disc brake seat and chain sprocket seat are implemented in axial location on the hind axle with sleeve pipe, nut and the jump ring in band equilateral polygon hole usually, the equilateral polygon hole of sleeve pipe one end cooperates with disc brake seat or chain sprocket seat, the equilateral polygon hole of the sleeve pipe other end cooperates with nut, nut thread is connected on the hind axle, and the part that nut exposes to sleeve pipe is equipped with jump ring sleeve pipe is carried out axial limiting.The used part of this location structure is more, and relates to the matching design in equilateral polygon hole, and there is the inconvenient problem of mounting or dismounting in complex structure, causes the cost of whole assembly higher.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and mounting or dismounting are convenient, and cost is low, and location failure-free rear axle shaft assembly of dune buggy.
For achieving the above object, the utility model provides a kind of rear axle shaft assembly of dune buggy, include hind axle, back pontic, disc brake dish and chain sprocket, back pontic is by the middle part of bearings at hind axle, disc brake dish, chain sprocket are separately fixed on disc brake seat, the chain sprocket seat, disc brake seat, chain sprocket seat lay respectively at pontic both sides, back and with hind axle between be spline and be connected, one of them dish seat outside in disc brake seat, the chain sprocket seat is by carrying out axial location to jacking nut, and the outside of another dish seat is by the jump ring axial location.
What the utility model utilized two nuts on hind axle makes the thread segment of hind axle be subjected to additional pulling force all the time to top effect, thereby makes the certain additional friction power of generation between screw thread to prevent nut loosening reliably.The influence of outer work condition such as this anti-loose structure can not shaken, jolt is to realize the reliable location of trailing wheel parts on shaft.The jump ring load that can not only withstand shocks satisfies the assembling and positioning requirement of dish seat, and it is convenient to have mounting or dismounting, repeatedly used advantage.A wherein place that needs to locate on hind axle uses jacking nut, and another place's jump ring to reduce the part number, is convenient to assembling, has reduced manufacturing cost.
The technique effect that the utility model is obtained is: the axial location of part such as back pontic, dish seat is reliable on the hind axle, and simple in structure, and mounting or dismounting are convenient, and cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Among the figure: 1. hind axle; 2. pontic after; 3. disc brake dish; 4. chain sprocket; 5. disc brake seat; 6. chain sprocket seat; 7. to jacking nut; 8. jump ring; 9. spline; 10. spline; 11. spline.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing, the rear axle shaft assembly of dune buggy that the utility model provides, have hind axle 1, back pontic 2, disc brake dish 3 and chain sprocket 4, back pontic 2 is by the middle part of bearings at hind axle 1, disc brake dish 3, chain sprocket 4 are fixed by bolts to respectively on disc brake seat 5, the chain sprocket seat 6, disc brake seat 5, chain sprocket seat 6 lay respectively at pontic 2 both sides, back and with hind axle 1 between be spline and be connected, the outside of disc brake seat 5 is by carrying out axial location to jacking nut 7, and the outside of chain sprocket seat 6 is by jump ring 8 axial location.
Because that utilizes two nuts on hind axle 1 makes the thread segment of hind axle 1 be subjected to additional pulling force all the time to top effect, thereby make the certain additional friction power of generation between screw thread to prevent nut loosening reliably.The influence of outer work condition such as this anti-loose structure can not shaken, jolt is to realize the reliable location of trailing wheel parts on shaft.Jump ring 8 load that can not only withstand shocks satisfies the assembling and positioning requirement of dish seat, and it is convenient to have mounting or dismounting, repeatedly used advantage.A wherein place that needs to locate on hind axle uses jacking nut, and another place's jump ring to reduce the part number, is convenient to assembling, has reduced manufacturing cost.
Also can adopt this location structure, that is: will be arranged on chain sprocket seat 6 outsides to jacking nut 7, jump ring 8 is arranged on the outside of disc brake seat 5; Perhaps, the outside of chain sprocket seat 6, disc brake seat 5 is all used jacking nut 7 is positioned.
Two nuts in the jacking nut 7 are all adopted minus thread, the direction of rotation of hind axle when advancing, the tight power when assembling to guarantee to remain between nut and the hind axle with vehicle.
The outside of jump ring mounting groove is a spline 9 on the hind axle 1, and the spline 10 that is used for installing disc brake seat and chain sprocket seat on this spline 9 and the hind axle is identical with 11 parameters.Spline 9 is identical with spline 11 parameters, has both guaranteed the complete symmetry of jump ring mounting groove two side, and it is stressed equably to be convenient to jump ring 8, and is convenient to can axially move smoothly when chain sprocket seat 6 is installed and removed.The parameter of spline 9, spline 10 and spline 11 is identical, adds can be shaped by a cutter man-hour, can cut down finished cost, and enhances productivity.
