Summary of the invention
In order to overcome above-mentioned defective, the object of the present invention is to provide a kind of simple in structure, turn to steering wheel walking tractor flexibly.
In order to achieve the above object, steering wheel walking tractor of the present invention, comprise walker tractor and with the wheel steering system of the separate control of described walker tractor operating system; Described wheel steering system comprises:
Bearing circle is movably arranged on the walker tractor;
Driving device, input end closure dish, mouth and the hinged track arm that is arranged on the drive wheel are hinged;
Handle lock is controlled the rotation of described bearing circle;
Diff cooperates wheel steering and driving;
Differential locking-device is arranged on the described diff;
Two actuators, cooresponding with it the respectively drive wheel of an end of each actuator is rotationally connected, and the other end is fixedly installed on the walker tractor respectively; The universal-joint that also comprises difference hinged axle drive shaft two ends and drive wheel.
Described differential locking-device moves opening and lock on the described diff between two gears, and differential locking-device is at the described gear of opening, and the described walker tractor of direction of passage dish, driving device and differential controls turns to; All at the locking gear, described wheel steering system is locked for differential locking-device and handle lock, turns to by the control of walker tractor operating system.
Particularly, described diff comprises that left and right two pairs drive the gear pair that two drive wheels rotate respectively; Described differential locking-device is controlled described diff in latched position and is quit work; Described differential locking-device is in open position diff normal operation.
Particularly, described driving device be gear and with the rack bar of described gear mesh, described gear is arranged on the drive link, described drive link one end is arranged on the bearing circle, the other end is arranged on the fixed link; Be set with conduit on the described walker tractor, rack bar one end and track arm are hinged, and the other end is arranged in the described conduit.
Further, with described track arm pivotally attached rack bar be divided into two sections hinged.
Further, described drive wheel lower end outwards is set with underarm respectively, is hinged with cross bar between the described underarm.
Wherein, described actuator is sleeve openings formula, arm-type or stent-type.
Wherein, described walker tractor is provided with two trailing wheels, and described trailing wheel top is provided with the compartment.
Further, described trailing wheel is a drive wheel, drives by drive mechanism respectively, and described drive mechanism is connected with the transmission system that drives described drive shaft turns.
The steering wheel walking tractor of said structure, because described bearing circle is movably arranged on the described walker tractor, when running at high speed on the ground, can drive by the direction of passage dish, and the action of energy direction of passage dish and driving device realizes turning between the drive wheel through the control of diff, the dangerous situation of avoiding at uphill/downhill or occurring in running at high speed; Under the situation of the hand steered lever operation of needs, bearing circle and diff are pinned, do not influence the functions of use of walker tractor, this compact conformation, easy to operate, turn to flexibly, safety performance is higher.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Figure 1-3, steering wheel walking tractor of the present invention, comprise walker tractor and with the wheel steering system of the separate control of described walker tractor operating system; Described wheel steering system comprises:
Bearing circle 1 is movably arranged on the walker tractor 12;
Driving device, input end closure dish 1, mouth and the hinged track arm 7 that is arranged on the drive wheel 8 are hinged;
Handle lock 19 (seeing shown in Figure 1) is controlled the rotation of described bearing circle;
Diff cooperates wheel steering and driving;
Differential locking-device 39 is arranged on the described diff;
Two actuators, 16, one ends are rotationally connected with two drive wheels 8 respectively, and the other end is fixedly installed on respectively on the walker tractor 12; The universal-joint 14 that also comprises difference hinged axle drive shaft 18 two ends and drive wheel 8.
Described differential locking-device moves opening and lock on the described diff between two gears, and differential locking-device is at the described gear of opening, and the described walker tractor of direction of passage dish, driving device and differential controls turns to; All at the locking gear, described wheel steering system is locked for differential locking-device and handle lock, quits work, and turns to by the control of walker tractor operating system, and former walker tractor function is normally used.
Above-mentioned structure, described bearing circle only could rotate under the situation that described handle lock is opened, and under the situation of described handle lock locking, described bearing circle can not rotate; When needing turning service orientation dish, at first handle lock is opened, differential locking-device is placed open gear (control of described handle lock and differential locking-device can open by interlinked mechanism, locking simultaneously; Also can independently open respectively and lock, specifically need to be provided with the driver), promote or the pulling track arm through driving device by the direction of operating dish, realize turning between the drive wheel, because diff makes the drive shaft speed that drives the rotation of two drive wheels inconsistent, thereby make turn direction control more flexibly accurately, described universal-joint makes the connection between axle drive shaft and the drive wheel more flexible, can realize that windup-degree change and driving, described actuator plays a supportive role, because end and the hinged setting of described drive wheel do not turn to so do not influence, the safety case of avoiding at uphill/downhill or occurring in running at high speed, this compact conformation, easy to operate, turn to flexibly, safety performance is higher, thereby finish turning to flexibly of trac., described universal-joint has increased the alerting ability that drive wheel rotates around described axle drive shaft coupling end, and described actuator and described trac. fixed end play a supportive role, and are rotationally connected with described drive wheel and avoid influencing the rotation of described drive wheel.
