Abstract

The invention relates to an automobile constant speed driving shaft. The automobile constant speed driving shaft comprises a left half axle and a right half axle, wherein the left end of the left half axle is assembled with a left side wheel through a left half axle fixed knot, the right end of the left half axle is assembled with a left side half axle gear of a differential mechanism in a power transmission device through a left half axle moving knot, the left end of the right half axle is assembled with a right side half axle gear of the differential mechanism in the power transmission device through a right half axle moving knot, the right end of the right half axle is assembled with a right side wheel through a right half axle fixed knot, the right half axle is of a hollow axle tube structure, the left half axle is of a solid rod axle structure, the length of the right half axle hollow axle tube is X, the length of the left half axle solid rod axle is Y, X is greater than Y, the torsion rigidity of the right half axle is K right, the torsion rigidity of the left half axle is K left, and the K right is equal to the K left. The automobile constant speed driving shaft not only solves the off-tracking problem during dynamic load acceleration running of the whole vehicle caused by inconsistent torsion angles of the left half axle and the right half axle, but also eliminates resonance phenomenon caused by different rotating speed working conditions of the engine, so that the NVH (Noise Vibration and Harshness) performances and economical performance of the vehicle are improved.

Description

technical field [0001] The invention relates to a driving shaft of an automobile transmission system, in particular to an automobile constant-velocity driving shaft, belonging to the technical field of automobile transmission shafts. Background technique [0002] With the improvement of people's requirements for the driving reliability and NVH performance of automobiles, the design level of various parts of automobile chassis is continuously improved. The impact on NVH performance cannot be ignored either. [0003] as attached figure 1 As shown, in the prior art, for front-wheel-drive vehicles and SUV vehicles, since the arrangement of the engine is biased to the left side of the vehicle body, the central axis I of the power transmission device 3 does not coincide with the central axis II of the vehicle body, so it is necessary to move the drive shaft to the right Half shaft 1 is designed longer and its shaft is designed as a solid structure with an external vibration damp...
