Description
Technical field
The present invention relates to king pin technical fields, specially vehicle mounted type king pin changing machine.
Background technique
General king bdt is mounted on the front axle of steeraxle, and front axle is basic part, and both ends are in fist shape
Thickened portion, referred to as key seat, wherein there is through-hole, stub is installed in this hole, and knuckle is connected by pin with front axle, makes front-wheel
Certain angle can be deflected around stub, to realize the steering of automobile, in order to make automobile keep stable straight-line travelling and turn to light
Just, after stub is mounted on front axle, upper end is tilted backwards in fore-and-aft plane, based on the angle of axis and front-wheel center vertical line
Back rake angle is sold, when automobile straight-line travelling, deflecting roller are slightly deflected by external force, road surface acts on one laterally instead to wheel
Active force makes wheel automatically revert to middle position, plays the role of making wheel self-aligning, and castor is excessive, can make
At hard steering, in addition, slope inwardly an angle in transverse plane when stub is mounted on front axle, it is Kingpin inclination foot,
When deflecting roller deflects under external force, front-wheel is returned to deflecting roller original under the action of automobile quality itself
Middle position, makes wheel self-aligning, manipulate it is more light, knuckle in the use process of vehicle due to running environment more
Complexity, therefore the life cycle of king pin is shorter, after king pin abrasion, will lead to four wheel locating parameter and changes
Become, cause vehicle in the process of moving, direction flexibility reduction, steering wheel is heavy, high speed pendulum shakes, tire wear aggravation, automobile
Maneuvering performance substantially reduce, not only increase the use cost of vehicle, and there is also greatly in the process of moving for vehicle
Security risk, it is therefore desirable to periodically by king pin disassembly be maintained or replaced, currently, replacement king pin when need
It will be replaced again after the disassembly of preceding bridge, skilled worker taps king pin with hammer and disengages it from knuckle, reaches disassembly
Purpose, long the time required to replacement, low efficiency, or in the case where bridge before not dismantling, tapping king pin with hammer makes it
It is detached from knuckle, the locational space as where king pin is smaller, and worker is not easy to wave hammer, therefore removal efficiency is very low, and
King pin central axes are not with horizontal plane, and when tapping, direction is not easy to hold, and difficulty is higher, therefore this mode needs
The higher skilled worker's operation of proficiency, is otherwise easy to damage knuckle, higher to the technology dependence of worker, into one
Step reduces the efficiency of disassembly, and because working environment is at vehicle bottom, narrow space is bad to put to good use, and the working time is again longer, so latent
Volt has biggish security risk.
