The specific embodiment
Below in conjunction with Figure of description the present invention is further specified.
Four wheel drive dual rotation running gear of the present invention; As shown in Figure 2; It comprises propons 2, the back axle 3 of being located at support body 1 downside, and front-wheel 4 is installed on the propons 2, and trailing wheel 5 is installed on the back axle 3; Front-wheel 4 is driven by preceding power 6 and is the preceding steering hardwares 7 of front-wheel 4 configurations, and trailing wheel 5 is driven by back power 8 and is trailing wheel configuration back steering hardware 9.This four wheel drive dual rotation running gear is through all being set to drive wheel and wheel flutter with front and back wheel; Can dwindle Turning radius; And simple to operate when equipment needs lateral offset, thus the lifting working platform maneuvering performance strengthened, can effectively enhance productivity, reduce potential safety hazard.
As further improving and replenishing to technique scheme; The present invention also comprises following additional technical characterictic; Though the major part that structure shown in Figure 2 can comprise in following all additional technical features constitutes preferred embodiment of the present invention; But the present invention is not limited to this situation, when embodiment of the present invention, according to concrete effect they is selected for use on the described technical scheme of epimere.
At first, preceding power 6, back power 8 be motor, driving engine or HM Hydraulic Motor, and shown in Figure 2 is by the motor-driven reductor, again spool being connected to front-wheel, trailing wheel transfer torque through transmission shaft and drive axle.
Secondly, preceding power 6, back power 8 are controlled by same control handle.Direction of operating like handle can be designed to work in coordination with the direct of travel of car load, and when advancing, handle pushes away forward, and handle pulls back when retreating.
The 3rd, preceding steering hardware 7, back steering hardware 9 are by electric pushrod or hydraulic oil cylinder driving.Shown in Figure 2 is to be to carry out power by hydraulic ram, oil cylinder flexible, and control wheel left-right rotation, two wheel steerings on the same vehicle bridge are connect by connecting rod to be realized rotating synchronously.Further, be the electric pushrod or the independently preceding pole changer of hydraulic oil cylinder driving configuration of steering hardware before driving, for electric pushrod or the hydraulic oil cylinder driving that drives the back steering hardware disposes independently back pole changer.For the ease of operation, preceding pole changer, back pole changer all can be located on the described handle.
As shown in Figure 3 when four wheel drive dual rotation running gear of the present invention is turned, rotate identical corner in the opposite direction and dwindle Turning radius by preceding steering hardware 7 control front-wheels 4, back steering hardware 9 control trailing wheels 5.Front-wheel described here, trailing wheel rotate in the opposite direction and are meant that front-wheel, trailing wheel belong to the direction of rotation of vehicle bridge with respect to it; Be illustrated in figure 3 as the state after front-wheel 4 rotates from state clockwise direction shown in Figure 2 with respect to back axle 3 from state anticlockwise motion shown in Figure 2, trailing wheel 5 with respect to propons 2; Thereby changed the position of instantaneous turning center; Reduce minimum turning radius R significantly, driven front-wheel, trailing wheel, the steering operation effect that can obtain to satisfy.
Can be as shown in Figure 4 during four wheel drive dual rotation running gear lateral offset of the present invention, rotate identical corner to same direction and realize lateral offset by preceding steering hardware 7 control front-wheels 4, back steering hardware 9 control trailing wheels 5.Described front-wheel, trailing wheel rotate to same direction and are meant that front-wheel, trailing wheel are identical with respect to the rotation direction of its place vehicle bridge; Be illustrated in figure 4 as front-wheel 4 with respect to propons 2, trailing wheel 5 with respect to the equal state behind the state anticlockwise motion shown in Figure 2 of back axle 3, drive front-wheel this moment, trailing wheel advances or retreat and can realize horizontal displacement.
Also can make propons 2, back axle 3 alternately alternately realize lateral offset during four wheel drive dual rotation running gear lateral offset of the present invention by preceding steering hardware 7 control front-wheels 4, back steering hardware 9 control trailing wheels 5 to same directional steering as fixed bridge and front-wheel 4, trailing wheel 5.Specifically, can select front-wheel 4 to turn to earlier, back axle 3 is promptly made in fixed bridge, and this moment, front-wheel was more first near the target location than trailing wheel under engine drives; When front-wheel 4 during near the target location, switch to that front-wheel does not turn to, trailing wheel is to the operation of advancing of same directional steering, this moment, trailing wheel 5 followed up and near the target location, one just can accurately be shifted back and forth easily.Otherwise, also can select trailing wheel 5 to turn to earlier, propons 2 is promptly made in fixed bridge, and this moment, trailing wheel 5 was more first near the target location than front-wheel under engine drives; When trailing wheel during near the target location, switch to that trailing wheel does not turn to, front-wheel is to the operation of advancing of same directional steering, this moment, front-wheel 4 followed up and near the target location, one just can accurately be shifted back and forth easily.
