Description
Technical field
The present invention relates to a kind of steering and driving axle of differential structure, belong to drive axle technical field.
Background technology
Many vehicles, the building equipment or farm equipment particularly moved in uneven earth's surface, usually using wheeled
Or crawler type is driven manipulation, transfer is hydraulic system, because working environment is relatively poor, hydraulic system is led to
Require higher with property, moment of torsion etc., there is the problem of fault rate is higher during use；Or to be driven respectively using bi-motor structure
The driving wheel crawler belt of dynamic both sides, but the delivery efficiency of two motors is difficult to holding synchronously, frequent sideslip during straight trip；And both are tied
The radius of turn of structure is big, turns dumb.Patent No. CN201610659175.2 patent discloses a kind of double differectial knot
The steering and driving axle of structure, but during the structure actual production, structure is more complicated, installs assembling and there is problem.
The content of the invention
According to deficiency of the prior art above, the technical problem to be solved in the present invention is：A kind of differential structure is provided
Steering and driving axle, both ensures the stabilization walked of turning, and ensures the simple accurate of assembling again.
The steering and driving axle of differential structure of the present invention, including power input device, power input device pass through cone
Gear train engagement connection power transmission shaft, power transmission shaft two ends are sequentially provided with travelling gear and central gear, and travelling gear is into C-shaped, C-shaped
Travelling gear be provided with external toothing and ring gear, coordinated between ring gear and central gear by some planetary gears, planetary gear
Wheel shaft is connected, wheel shaft connection road wheel, two external toothings connect semiaxis by transmission mechanism, and the relative one end of two-semiaxle passes through cone
Gear train connection differential driving.
During advance, differential driving does not work, and power input device drives drive axis, and power transmission shaft drives the transmission at two ends
Gear and central gear synchronous axial system, so as to drive road wheel to advance；When needing to turn to, differential driving work, differential driving is logical
Crossing bevel gear set drives two semiaxis to rotate, the ends of two semiaxis by transmission mechanism band nutating gear, travelling gear with
Planetary gear is engaged, and travelling gear is asynchronous with central gear to be rotated so that the walking wheel speed of both sides is different, realizes and turns to.
It is preferred that, semiaxis one end is gear, is engaged with the external tooth of travelling gear, and the other end of semiaxis is bevel gear, semiaxis
It is driven between end and travelling gear by gear drive.
It is preferred that, semiaxis one end be sprocket wheel, connected between sprocket wheel and the external tooth of travelling gear by chain, semiaxis it is another
Hold as bevel gear, be driven between half shaft end and travelling gear by chain-drive mechanism.
It is preferred that, travelling gear is by bearing on power transmission shaft.
It is preferred that, differential is driven to motor or hydraulic motor.
It is preferred that, some planetary gears connect rotating disk by planet wheel spindle, and rotating disk is provided with wheel shaft, wheel shaft connection road wheel.
The present invention is had an advantageous effect in that compared with prior art：
The steering and driving axle of differential structure is reasonable in design, changes traditional steering driving structure, both ensure that straight line, has turned
Curved walking stabilization, walking of turning is flexible, radius of turn is small, in turn ensure that reliability, the accuracy when production is assembled, and with poor
The function of speed lock, good mechanical property, fault rate is low.
