The structure and function of cardan shaft,itSimilar to the human bodyStructureJoints, allowing the angle between the connected parts to vary within a certain range.In order to meet the power transmission, steering andMaster deviceRuntime, 以The angle change caused by the up and down swing, driving forwardMaster deviceDrive axle, connect common joints between axle shafts.However, due to the limitation of the axial size, the deflection angle is required to be large, and a single joint cannot be used.Cardan shaftThe instantaneous angular velocities are equal.
Especially for general-purpose shafts with high corrosiveness,universalThe shaft designer adopts national standards,Thus, in选择universalWhen shaft products, need to meet the requirements of use.needNumberCardan shaft connection.OnMaster deviceUneven road surface vibration during operation, etc.,becauseEasy to cause vibration,The parts are severely damaged,以Produces a lot of noise, so various constant velocity joints are widely used.In a front drive vehicle, each axle shaft has two constant velocity joints, and the joint close to the drive axle is the inner joint of the axle shaft.universal轴The separation process is different, in order toMakeRear driveMaster deviceType of coupling transmission.All adopt double coupling.
如果Cardan shaftThe device has a problem of inferior quality, the drive shaft device must be replaced, usually the shaft must be replaced.Of course it needs to be repaired and assembled, but nowCardan shaftThere are also many types and different structures,Cardan shaftThe separation process is different, the evaluation during cleaningCardan shaftThe cleaning state is relatively necessary after separation.Operate different parts,Cardan shaftParts andCardan shaftThe disassembly of the parts is very important.
AboutOf the deviceDisassembly is determined according to the location of the repair, and the part of the connected shaft needs to be relatively distinguished.Cardan shaftThe components on the opposite side are separated, so it is necessary to master the method and method of disassembly,Cardan shaftThere are various types,among themThere are couplings at both ends of the drive shaft, whose function is to make the angles at both ends of the drive shaft equal.To improve performance.
