Technical field
The utility model belongs to mechanical fitting technical field, relates to live axle semiaxis and improves structure.
Background technique
While driving live axle that automobile uses to install input end substantially do not have fixed structure or fixed structure unreasonable, develop rapidly along with automotive industry, to vehicle, indices requirement is more and more higher under steam, how to adapt to the development of automotive industry, will suitably improve orthodox car structure, comprising drive shaft assembly, drive shaft assembly with fixed structure has just arisen at the historic moment, and there are German GKN company, ZF company, Japanese NTN company and U.S. Dana etc. in the company that produces in the world at present drive shaft assembly.Above-mentioned company is except at typical fixed, the leading whole world in telescopic type structure, GKN group and Japanese NTN company have developed AAR type trip slip ring three axis of a cylinder formulas, freely swing shaft type and belong to TG (needle roller) type in TRJ type of FOX type, TB (steel ball) type movable joint, their common feature is frictional force, axial resistance is less, transmitting torque ability increases, yet when drive shaft assembly industrialization production makes a breakthrough, be faced with (the noise Noise with NVH abroad, vibration Vibration, whistle Harshness) the many problem demanding prompt solutions centered by, and the caused noise and vibration of drive shaft assembly is one of root of these problems.Large activity angling in addition, because the least radius of gyration of automobile depends on maximum wheel drift angle while turning to, thereby require external drive shaft assembly can have large as far as possible movable corner, in addition also have protective housing high temperature resistant, revolution expansion issues, lubricating grease research etc., existing live axle is because the structure of semiaxis arranges unreasonable, connecting when being connected wheel position not firmly, ball cage assembly easily comes off, and can not adapt to complicated pavement state, and bearing capacity is also poor, and steel ball can be stressed irregular in alley, produces play, cause live axle running unstable.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple and reasonable, and bearing capacity is strong, and the live axle semiaxis that transmitting torque is large improves structure.
The utility model solves the problems of the technologies described above adopted technological scheme: live axle semiaxis improves structure, comprise Qiu Longke district and coupling shaft district, it is characterized in that, described ball cage shell is divided into main part, end caps portion, transition joint and shell are inner, described end caps portion is positioned at the periphery of main part, in end caps portion, offer six locking apertures, described transition joint is connected between coupling shaft district and main part, described transition joint from top to bottom has four ladder arc-shaped sides, on the centre of described shell inside, be provided with stationary axle, on the both sides of described stationary axle, offer the bayonet socket that is equipped with semicircular in shape.
The measure of taking for optimization such scheme specifically comprises:
At above-mentioned live axle semiaxis, improve in structure, on the right part in described coupling shaft district, have spline structure, the angle of described spline structure is 30 °, on the output terminal of spline structure, is provided with fixed connector.
At above-mentioned live axle semiaxis, improve in structure, four described ladder arc-shaped sides are divided into the first arc-shaped side, the second arc-shaped side, three-arc-side and four-arc edge, are provided with isolation shoulder block portion between the second arc-shaped side and three-arc-side.
At above-mentioned live axle semiaxis, improve in structure, the minimum distance of two described bayonet sockets is 38.5mm.
Compared with prior art, the one end that the utility model has the advantage of Qiu Longke district arranges end cap, can guarantee that lubricant grease is arranged in bottom of trench region, extend lubrication time, transition joint from top to bottom has four ladder arc-shaped sides and can guarantee to coordinate closely with after other parts installation, and by the stationary axle in Qiu Longke district, retainer is positioned, guarantee that like this steel ball is stressed even in alley, minimizing is to retainer, the wearing and tearing of shell, make live axle smooth running, in the situation that driving angle changes greatly, also can keep certain working stability, can adapt to complicated pavement state, and constant speed transmission is effective.
