Abstract
The utility model provides a half-shaft connecting structure which solves the problem that the connection between an inner half shaft of an existing steering and driving front axle and a cardan joint and the connection between an outer half shaft of the existing steering and driving front axle and the cardan joint are prone to damage. The half-shaft connecting structure comprises an outer half shaft, an inner half shaft and a cardan joint assembly. An inner half shaft sleeve is fixed to the driving end of a CV joint, and an outer half shaft sleeve is fixed to the driven end of the CV joint. One end of the inner half shaft is inserted in the inner half shaft sleeve, and one end of the outer half shaft is inserted in the outer half shaft sleeve. A spring is arranged in the outer half shaft sleeve, one end of the spring is fixed to the driven end of the CV joint, and the other end of the spring abuts against the end face where the outer half shaft is inserted in the outer half shaft sleeve.
Description
Technical field
The utility model relates to a kind of automobile front axle jack shaft, particularly a kind of half Axile connection structure.
Background technology
At present, the low speed driving small engineering machineries such as loader, excavating machine are due to its road surface, working space complexity, and propons mostly is steering drive axle, and the structure composition of steering drive axle had both had main reduction gear, diff and the semiaxis that general drive axle has; Also there are steering swivel housing, stub and wheel hub etc. that general steeraxle has.It is compared with independent drive axle, steeraxle, its difference is, turn to required semiaxis to be divided into two sections, be respectively inner shaft (being connected with diff) and outer semiaxis (being connected with wheel hub), the two couples together with universal-joint, existing inner shaft, outer semiaxis adopt relatively-stationary connection mode with being connected of export-oriented joint more, this connection structure, in the time of wheel steering and on complex road surface, rise and fall while jolting, the easy fracture damage of connection location between semiaxis and universal-joint, the as easy as rolling off a log wearing and tearing of semiaxis.
Utility model content
The utility model proposes a kind of half Axile connection structure, what solve the inner shaft of existing steer drive front-axle, outer semiaxis and universal-joint is connected the problems such as easily damage.
The technical solution of the utility model is achieved in that
A kind of half Axile connection structure, comprises outer semiaxis, inner shaft and universal joint assembly, and the drive end of described ball cage universal-joint is installed with inner shaft sleeve pipe, and the driven end of ball cage universal-joint is installed with outer axle tube; One end of described inner shaft is inserted in described inner shaft sleeve pipe, and one end of described outer semiaxis is inserted in described outer axle tube; In described outer axle tube, be provided with spring, and one end of described spring is fixed on the driven end of described ball cage universal-joint, the other end contacts at described outer semiaxis, and it is inserted on the end face in described outer axle tube.
Further, described outer semiaxis is inserted in one end that one end in outer axle tube and described inner shaft be inserted in inner shaft sleeve pipe and is all provided with vertically spline; The inwall of the inwall of described outer axle tube and inner shaft sleeve pipe is equipped with the spline suitable with described spline.
Further, the other end of described inner shaft is axially arranged with spline along it.
Known by above description, the utility model compared with prior art, the utlity model has following advantage:
One end of inner shaft is inserted in inner shaft sleeve pipe by the utility model, and one end of outer semiaxis is inserted in one end of outer semiaxis; When in vehicle operating process, wheel steering or encounter complex road surface, when front-wheel run-off the straight, outer semiaxis is vibration among a small circle in axle tube outside, by spring being set in axle tube outside, can play buffer action, the impulsive force while reducing outer semiaxis vibration, guarantee can reset in time after vibration simultaneously, life-saving.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, a kind of half Axile connection structure, comprises inner shaft 11, outer semiaxis 12 and universal joint assembly 2, and the drive end of described ball cage universal-joint 2 is installed with inner shaft sleeve pipe 31, and the driven end of ball cage universal-joint 2 is installed with outer axle tube 32; One end of described inner shaft 11 is inserted in described inner shaft sleeve pipe 31, and one end of described outer semiaxis 12 is inserted in described outer axle tube 32; In described outer axle tube 32, be provided with spring 5, and one end of described spring 5 is fixed on the driven end of described ball cage universal-joint 2, the other end contacts at described outer semiaxis 12, and it is inserted on the end face in described outer axle tube 32.
Semiaxis of the present utility model adopts spline drived, is therefore inserted at described outer semiaxis 12 one end that one end in outer axle tube 32 and described inner shaft 11 be inserted in inner shaft sleeve pipe 31 and is all provided with vertically spline 4; The inwall of the inwall of described outer axle tube 32 and inner shaft sleeve pipe 31 is equipped with the spline suitable with described spline.The other end of described inner shaft 11 is also axially arranged with spline 4 along it.When under the drive of inner shaft 11 at retarder, on the spline of spline engagement on inner shaft 11 in inner shaft sleeve pipe, and then drive ball cage universal-joint 2 to rotate by inner shaft sleeve pipe 31, the outer axle tube 32 that is connected to ball cage universal-joint 2 driven ends is synchronously rotated, spline engagement on spline in outer axle tube 32 and described outer semiaxis, drive outer semiaxis to rotate, and then drive the vehicle being connected on outer semiaxis to rotate, realize transmission.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
