Two differential mechanism inputs connect driving means, and the second differential mechanism both sides connect the second semiaxis, and two the second semiaxis are provided with second
Gear, is connected by gear drive between two group of first semiaxis and the second semiaxis, and turning to of two the second semiaxis is contrary.
When normally advancing, driving axis drives driving wheel or drives crawler belt to advance, and two the first semiaxis rotating speeds, turns to phase
With, under the effect of gear drive, two the second half axle steers are contrary；When turning to, driving means drives the second differential mechanism
Work, drives two the second semiaxis, and two the second semiaxis rotating speeds are different, thus the rotating speed of two the first semiaxis is different, thus real
Turn now to.When the input of the second differential mechanism locks, planetary gear the rotation of the second differential mechanism is not revolved round the sun, thus first is poor
The planetary gear of speed device only revolves round the sun not rotation, forms differential lock function.
Preferably, the first gear and the second gear are bevel gear, and gear drive includes that power transmission shaft, power transmission shaft two ends set
There is drive bevel gear, the first gear on respectively with two groups of semiaxis of two drive bevel gear, the second gear engagement.
Preferably, the first gear and the second gear are roller gear, and gear drive is a transmission roller gear, two
One group of first gear on group semiaxis and the second direct geared engagement, another organizes the first gear and the second gear by transmission cylinder
Gear engages.
Preferably, the first gear and the second gear are roller gear, and gear drive is Cylinder Gear wheels, two groups of semiaxis
On the first gear and the second gear all by Cylinder Gear wheels engagement connect, the number of gears ratio of one of which Cylinder Gear wheels
Few one of the number of gears of another group Cylinder Gear wheels.
Preferably, roller gear is spur gear or helical gear.
Preferably, the driving means that the second differential mechanism input connects is motor, hydraulic motor or power-assisted direction device.
The present invention is compared with prior art had the beneficial effect that
The steering and driving axle of double differectial structure is reasonable in design, changes traditional driving structure that turns to, straight line, row of turning
Walking stable, walking of turning is flexible, radius of turn is little, and has the function of differential lock, good mechanical property, failure rate is low.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
Embodiment 1
As it is shown in figure 1, the steering and driving axle of double differectial structure includes driving axle housing, band differential is installed in the middle part of driving axle housing
The main reducing gear of device assembly, differential mechanism both sides connect semiaxis, and the differential mechanism in main reducing gear is the first differential mechanism 4, poor with first
Two semiaxis that speed device 4 connects are the first semiaxis 1, and two the first semiaxis 1 are provided with the first gear 2；Also include the second differential mechanism
6, the second differential mechanism 6 input connects driving means 5, and the second differential mechanism 6 both sides connect the second semiaxis 7, on two the second semiaxis 7
It is provided with the second gear 8, is connected by gear drive between two group of first semiaxis 1 and the second semiaxis 7, two the second semiaxis 7
