Along with the raising of the high speed maneuverability requirement of wheel type mobile vehicle, apply traditional hinged steering gear and cannot meet service requirements.
Summary of the invention
A kind of wheeled vehicle steering gear that the purpose of this utility model provides for weak point existing in above-mentioned prior art just.
Steering gear of the present utility model except have tradition hinged turn to vehicle tight turn radius, working condition maneuverability, except operation efficiency advantages of higher, there is less turning radius, horizontal stability when advancing at a high speed higher, it is ensured that the high speed maneuvering ability of vehicle.
The purpose of this utility model realizes by following technique measures:
Wheeled vehicle steering gear of the present utility model comprises Rear frame, the front frame combined with Rear frame by hinged mechanism and left and right hinged steering cylinder, and by the near front wheel that left front hinged mechanism is connected with front frame, the off-front wheel being connected with front frame by right front hinged mechanism, the near front wheel steering cylinder being connected between the near front wheel and front frame, the off-front wheel steering cylinder being connected between off-front wheel and front frame, the pull bar being connected between the near front wheel and off-front wheel.
Left hinged steering cylinder described in the utility model, right hinged steering cylinder, the near front wheel steering cylinder, off-front wheel steering cylinder are double-act-ing hydraulic J-Horner, and hinged place, oil cylinder two ends is closed and is provided with oscillating bearing.
Described pull bar is flexible bolt-type pull bar, by plugging the mode of bearing pin, it is possible to realize fixed length formula pull bar fast to Telescopic handle two kinds of pattern switchings. The hinged steering cylinder of the hinged steering cylinder in a described left side and the right side is arranged in the way of alter-parallel, namely the rodless cavity of the rod chamber of left hinged steering cylinder steering cylinder hinged with the right side is connected, the rod chamber of the rodless cavity steering cylinder hinged with the right side of left hinged steering cylinder is connected, when the piston rod of left hinged steering cylinder stretches out, the piston rod of right hinged steering cylinder is retracted.
The beneficial effects of the utility model are as follows:
Hinged steering gear work when low speed 1, can be realized, wheel steering device does not work, and makes vehicle have less turning radius, effectively improves operation efficiency, meets narrow and small Active workings demand;
Wheel steering device work when 2, can realize advancing at a high speed, hinged steering gear does not work, thus improves the horizontal stability of vehicle, especially when high speed steering, avoids hinged steering structure vehicle the defect of Cross deformation easily occur;
3, owing to wheel steering device of the present utility model adopts two double-act-ing hydraulic J-Horners, these two wheel steering cylinders can control separately work, and the latch at pull bar is extracted, it is achieved after float extension bar, makes two wheels realize different angle of turning;
4, latch at pull bar is extracted, after realizing float extension bar, it is possible to when realizing low speed hinged turn to turn to wheel work simultaneously, it is achieved on the hinged basis turned to, turning radius is reduced more than 25% again, is applicable to the turning to of the special narrow place such as road, lane, reverses end for end;
5, owing to adopting two identical double-act-ing hydraulic J-Horner alter-parallels between forward and backward vehicle frame, it is possible to ensureing that left and right turn speed is identical with angle of turning, steering force is bigger.

Fig. 1 is the structural representation of a kind of wheeled vehicle steering gear.
Fig. 2 is the structural principle schematic diagram of a kind of wheeled vehicle steering gear.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1 and Figure 2, wheeled vehicle steering gear of the present utility model comprises Rear frame 1, the front frame 3 combined with Rear frame 1 by hinged mechanism 12 and left and right hinged steering cylinder 2,11, and by the near front wheel 4 that left front hinged mechanism 5 is connected with front frame 3, the off-front wheel 10 being connected with front frame 3 by right front hinged mechanism 9, the near front wheel steering cylinder 6 being connected between the near front wheel 4 and front frame 3, the off-front wheel steering cylinder 8 being connected between off-front wheel 10 and front frame 3, the pull bar 7 being connected between the near front wheel 4 and off-front wheel 10.
Left hinged steering cylinder 2 described in the utility model, right hinged steering cylinder 11, the near front wheel steering cylinder 6, off-front wheel steering cylinder 8 are double-act-ing hydraulic J-Horner, and hinged place, oil cylinder two ends is closed and is provided with oscillating bearing.
Described pull bar 7 is flexible bolt-type pull bar, by plugging the mode of bearing pin, it is possible to realize fixed length formula pull bar fast to Telescopic handle two kinds of pattern switchings.
More specifically: the hinged steering cylinder in a described left side 2 is arranged with the right side hinged steering cylinder 11 alter-parallel, namely the rodless cavity of the rod chamber of left hinged steering cylinder 2 steering cylinder 11 hinged with the right side is connected, the rod chamber of the rodless cavity steering cylinder 11 hinged with the right side of left hinged steering cylinder 2 is connected, when the piston rod of left hinged steering cylinder 2 stretches out, the piston rod of right hinged steering cylinder 11 is retracted, realize front frame 3 to turn clockwise around hinged mechanism 12 relative to Rear frame 1, realize the right turn of vehicle, with reason, when the piston rod of the hinged steering cylinder 2 in a left side is retracted, the piston rod of right hinged steering cylinder 11 stretches out, realize front frame 3 to be rotated counterclockwise around hinged mechanism 12 relative to Rear frame 1, the left-hand rotation realizing vehicle to.
