Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The embodiment one of the poleless aircraft tractor of the utility model, as shown in Figure 1 to Figure 2, the poleless aircraft tractor
Including body 1, body 1 includes rack and wheel group, and the rear portion of rack is provided with preceding support construction, passes through preceding support construction
4 are played before carrying volt aircraft on the back, in the present embodiment, wheel group includes driving wheel and universal wheel, and arrangement form is that the trailing wheel of body 1 is set as
Direct wheel drives wheel 2, front-wheel are set as universal wheel 3, and wherein Direct wheel drives wheel 2 includes wheel hub motor, In-wheel motor driving device etc.,
In the present embodiment, realization machine is changed by the differential of Direct wheel drives wheel primarily to realizing by the setting of Direct wheel drives wheel 2
The steering of body 1, such steering mode can realize that the no-radius of poleless aircraft tractor turns to, and steering is relatively flexibly freer,
It is handling preferably, and by way of rear wheel drive and differential steering, can reduced moment transfer mode, shorten failure chain,
And the complexity of system is reduced, if abort situation can also be found faster by breaking down during actual driving.
Meanwhile for preceding support construction comprising support plate 5, support plate 5 are equipped with for being risen before positioning aircraft
4 preceding 41 position of axis and with the positioning region 51 played axis 41 before 4 and be total to facade is played before aircraft, meanwhile, which sets
Seated position can ensure that the driving wheel axis 21 of two above-mentioned Direct wheel drives wheels 2 is total to facade with positioning region 51 and be risen before making aircraft
4 supports are arranged on 21 place facade of driving wheel axis.4 axial location is played before aircraft to be located at where the axial location of driving wheel
On facade, in this way setting can be risen before by aircraft 4 be fixed in support plate 5 after, 4 weight is played before aircraft all by wheel side
Driving wheel 2 is born, and to increase the contact area of Direct wheel drives wheel 2 and ground, and this setup can increase
The friction coefficient of Direct wheel drives wheel 2 and ground, and then can mitigate original in order to ensure between Direct wheel drives wheel 2 and ground
Friction coefficient and 1 weight of increased body；Meanwhile such setting form can also mitigate the stress of auxiliary universal wheel 3, in turn
Reduce steering drag, ensures the flexibility of differential steering.
Meanwhile in the present embodiment, above-mentioned positioning region 51 is located at the center between two driving wheels, in this way can
Ensure that two 2 stress of Direct wheel drives wheel are consistent, the further flexibility for ensureing to turn to.
The mounting groove for installing Direct wheel drives wheel 2 is provided in above-mentioned rack, mounting groove is separated into two by partition board
Point, a portion constitutes motor mounting part, and another part constitutes driving wheel mounting portion.
The embodiment two of poleless aircraft tractor involved by the utility model：With embodiment one the difference is that,
It is arbitrarily devised according to practical situation as shown in figure 3, the wheel group in rack can have three groups, ensure rubbing for driving wheel and ground
Wipe that coefficient is sufficiently large and the steering drag on universal wheel and ground is sufficiently small.
The embodiment three of poleless aircraft tractor involved by the utility model：With embodiment one the difference is that,
As shown in figure 4, playing the deviation position of one of them between being positioned in two driving wheels before aircraft.
Certainly, in other embodiments, trailing wheel can also only be provided as onward impulse driving wheel, set front-wheel to
Deflecting roller is turned to by deflecting roller, and driving wheel provides the power for advancing and retreating, although setting can make the transmission of torque in this way
Mode is complex, and failure chain is longer, but will play 4 before aircraft and be supported on the axis place facade of driving wheel, also can
Enough ensure the friction coefficient of driving wheel and ground, and deflecting roller both may be implemented to turn to it is only necessary to bear the weight of tractor
Function, traction are also more convenient.
Involved by the utility model is suitable for the running gear that is drawn to aircraft, such as tractor without bar tractor
Deng, in the present embodiment major embodiment be wheel drive mode, in other embodiments, can also be applied to other modes drive
In.
In the embodiment of the embodiment of rack involved by the utility model, structure and above-mentioned poleless aircraft tractor
Rack structure it is consistent, be no longer developed in details.
