Abstract

The invention provides an automobile and a front axle inner half shaft thereof. The automobile front axle inner half shaft comprises an integrated shaft structure, the shaft structure comprises a shaft rod portion, a gear sleeve portion and a transition portion, the diameter of the shaft rod portion is a first number value, the diameter of the gear sleeve portion is a second number value, the first number value is smaller than the second number value, the transition portion is connected with the shaft rod portion and the gear sleeve portion, an outer spline is arranged at the tail end of the shaft rod, and an inner spline is arranged at the tail end of the gear sleeve portion. The automobile front axle inner half shaft is integrated and avoids a fact than a plurality of components are welded to form a traditional automobile front axle inner half shaft, and the firmness of the automobile front axle inner half shaft is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an inner axle shaft of an automobile front axle and an automobile. Background technique [0002] The front drive axle of light-duty off-road vehicles generally adopts a disconnected drive axle structure. This kind of drive axle is used in conjunction with independent suspension, which can not only meet the dynamic performance of all-wheel drive of off-road vehicles, but also take into account the ride comfort of the vehicle. [0003] In the front drive axle, due to the layout of the transmission line of the vehicle chassis, there is often a certain offset between the final drive and the center line of the vehicle. Steering drive half shafts are of equal length design. Therefore, in order to compensate for the deviation between the final drive axle final drive and the center line of the vehicle, it is necessary to add a separate front axle inner half shaft to realize torque transmission...
