The utility model in order to solve its technical problem used by technical solution be：Rear side in a kind of aerial work platform
Driving wheel positions small space turning device, including being arranged on the foresteerage gear of job platform tray bottom and rear-axle steering machine
Structure, the foresteerage gear is by steering front wheel one, steering front wheel two, wheel seat one, wheel seat two, rocking bar and driving steering front wheel
First, the running motor composition that steering front wheel two is walked, the steering front wheel one, steering front wheel two are separately mounted to wheel seat one, wheel
On seat two, wheel seat one, wheel seat two, one end of rocking bar and running motor are separately mounted to job platform tray bottom, and walk horse
It is hinged up to the other end and rocking bar, rocking bar both ends are respectively articulated with connecting rod one and connecting rod two, and connecting rod one and connecting rod two, which are divided into, does not pass through wheel
Seat king pin with wheel seat realizes and is hinged that the centre position of rocking bar is rocking bar axle center, and rocking bar axle center is fastened on oil cylinder installing plate
On steering cylinder, tire is connected with tire dolly.
As further improvement of the utility model, the wheel seat one, the centre position of two top of wheel seat are determined equipped with shaft
Position seat, is connected by shaft positioning seat with job platform tray bottom.
As further improvement of the utility model, the connecting rod one and connecting rod two avoid occurring with wheel seat king pin for one
Interfere the connecting rod of arc-shaped.
The beneficial effects of the utility model are：The utility model uses overall system control（Electronic or electro-hydraulic control may be selected
System）, coordinate steering and driving function, while can realize the no-radius steering around interior rear side driving wheel, overall structure structure has both
It turns to and controls, compact overall structure.
By carrying out innovative design to foresteerage gear, it is proposed that new eight-linkage mechanism technically overcomes
For existing aerial work platform there are the technological deficiency of the larger radius of gyration, the highly difficult technology for realizing zero radius of turn will
It asks, reduces requirement of the aerial work platform to working region to a certain extent, can realize high-altitude in smaller working region
The flexible movement of job platform improves the applicability of aerial work platform.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
0 radius of turn described in us：When referring to Vehicular turn, vehicle is around trailing wheel center axis rotation.In Fig. 1, forward
It intersecting at a point to the normal and the normal of 22 direction of steering front wheel of one 1 directions of wheel, this point is the axle center of rear steering wheel 2 13,
So when vehicle turns in the direction of arrows, steering front wheel 1, steering front wheel 22 and rear steering wheel 1 are around rear rear steering wheel
2 13 axle center rotation, turning radius 0.
To realize 0 above-mentioned radius of turn, Fig. 2 shows rear side driving wheel in a kind of aerial work platform of the utility model
A kind of embodiment of small space turning device is positioned, including being arranged on the foresteerage gear of job platform tray bottom with after
Take turns steering mechanism, the foresteerage gear by steering front wheel 1, steering front wheel 22, wheel seat 1, wheel seat 24, rocking bar 5 with
And running motor 6 forms, the steering front wheel 1, steering front wheel 22 are separately mounted to wheel seat 1, on wheel seat 24, wheel seat one
3rd, one end of wheel seat 24, rocking bar 5 and running motor 6 is separately mounted to job platform tray bottom, 6 other end of running motor
Hinged with rocking bar 5,5 both ends of rocking bar are respectively articulated with connecting rod 1 and connecting rod 28, and connecting rod 1 and connecting rod 28, which are divided into, does not pass through wheel seat
King pin 9 with wheel seat realizes and is hinged that the centre position of rocking bar 5 is rocking bar axle center 10, and rocking bar axle center 10 is fastened on oil cylinder peace
