Description
Technical field
The utility model relates to vehicular field, in particular to a kind of fast changeable automobile axle shaft.
Background technique
Semiaxis is usually made of the universal driving device and jackshaft at both ends, and universal driving device can guarantee semiaxis in vehicle
Still has transmission agency when moving up and down；For the vehicle of front-wheel forerunner or four-wheel drive, semiaxis not only needs to adapt to wheel
The case where bounce, will also guarantee that vehicle power transmitting when turning is not interrupted, and therefore, semiaxis needs to meet following functions:
1, pivot angle is as big as possible, can be still driven with meeting the operating condition of wheel hop and turning；
2, good axial restraint guarantees that semiaxis will not fall off when vehicle operation, lead to dynamic failure；
For the axial restraint mode of semiaxis, usually semiaxis and universal driving device, universal driving device and differential mechanism,
Circlip is used between universal driving device and wheel hub or is screwed.For off-road vehicle semiaxis in practice, due to
Complex road condition often has excessively curved etc. operating conditions of emergency braking, the limit, these operating condition lower half axle loads steeply rise, it is possible to lead to semiaxis
It destroys.By previous experiences, the failure mode of semiaxis is usually expressed as the fracture of jackshaft or the destruction of universal joint, needs to carry out
Replacement.Due to existing semiaxis axial restraint mode, so that semiaxis generally requires cooperation disassembly suspension when replacing, wheel vacates work
Industry space, and then lead to complex procedures, time-consuming lengthens.
