The driving wheel crawler belt of dynamic both sides, but the delivery efficiency of two motors is difficult to keep synchronous, 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, and problem be present in installation assembling.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than：A kind of differential knot is provided
The steering and driving axle of structure, both ensure the stabilization walked of turning, ensure the simple accurate of assembling again.
The steering and driving axle of differential structure described in the utility model, including power input device, power input device lead to
Bevel gear set engagement connection power transmission shaft is crossed, both ends of the drive shaft is sequentially provided with travelling gear and central gear, and travelling gear is into C
Shape, the travelling gear of C-shaped are provided with external toothing and ring gear, coordinated between ring gear and central gear by some planetary gears,
Planetary gear connects wheel shaft, takes turns axis connection road wheel, and two external toothings connect semiaxis, the relative one end of two-semiaxle by transmission mechanism
Differential is connected by bevel gear set to drive.
During advance, differential driving does not work, and power input device drives drive axis, and power transmission shaft drives the transmission at both 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 led to
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 engages, travelling gear rotation asynchronous with central gear so that the walking wheel speed of both sides is different, realizes and turns to.
Preferably, 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.
Preferably, semiaxis one end is sprocket wheel, is 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.
Preferably, travelling gear is mounted on power transmission shaft by bearing.
Preferably, differential is driven to motor or hydraulic motor.
Preferably, some planetary gears connect rotating disk by planet wheel spindle, and rotating disk is provided with wheel shaft, takes turns axis connection road wheel.
Possessed beneficial effect is the utility model 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, turning, walking is flexible, radius of turn is small, in turn ensure that reliability, accuracy when production is assembled, and with poor
The function of speed lock, good mechanical property, fault rate are low.
