Abstract
The utility model discloses a towing tractor capable of turning around on the spot and being used on both a highway and a railway. The towing tractor comprises a chassis, four driving motors, four tires, four frequency converters and four wheelworks; wherein one end of each wheelwork is fixedly connected with a shell of the corresponding driving motor; a driving rotating shaft of each driving motor is in transmission connection with the corresponding tire; the control signal output end of each frequency converter is connected with the control signal input end of corresponding driving motor. According to the towing tractor capable of turning around on the spot and being used on both the highway and the railway, all the tires can rotate freely, the four frequency converters are used for controlling the corresponding driving motors independently, the driving motors control the rotating speeds of the corresponding tires, as a result, the turning directions of all the tires can be easily controlled according to rotating speed differences between all the tires, and the towing tractor can turn around. The towing tractor capable of turning around on the spot and being used on both the highway and the railway is convenient to operate and needs a small space for turning around and reversing.
Description
Technical field
The utility model relates to a kind of highway and railway double duty tractor, relates in particular to a kind of highway and railway double duty tractor of energy pivot turn.
Background technology
Train locomotive (comprising railcar) when maintenance, need in special maintenance storehouse, overhaul, and in maintenance storehouse, be what not allow to install for the high-voltage fence of train driving.Now need special-purpose tractor truck by train locomotive from maintenance storehouse traction to overhauling in storehouse.Tradition tractor truck is loaded onto a hitch matching with train locomotive hitch in one end of car, when tractor truck gets on the right track, allow one end of hitch to train locomotive, the mode of travelling of tractor truck is similar to automobile, the first angle angled with track of wheel, wheel open get on the right track after deflection wheel travel direction again, make wheel and parallel track, then continue to travel, until four wheels of tractor truck during all at track correct position, put down track adjusting wheel, restriction tractor truck can only travel in orbit.Make the mutual interlock of tractor truck hitch and train coupler, that realizes train locomotive leads car operation.Because track is narrow, the vacant lot limited space of maintenance storehouse outside, and tractor truck turn around need to be larger the reasons such as turn radius, caused the tractor truck process complexity that turns around, difficulty is large, needs special skilled person to operate just and can assure success.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of highway and railway double duty tractor of energy pivot turn.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of highway and railway double duty tractor of energy pivot turn, comprise chassis, four drive motor, four tires, four frequency converters and four wheel words, one end of described wheel word is fixedly connected with the shell of described drive motor, the drive shaft of described drive motor and described tire are in transmission connection, and the control signal mouth of described frequency converter connects with the control signal input end of corresponding described drive motor respectively.
Particularly, described wheel word comprises steering shaft, two bearings and L-type support plate, described steering shaft vertically arranges through described chassis, the bottom of described steering shaft is fixedly connected with the horizontal ends of described L-type support plate, the vertical end of described L-type support plate is fixedly connected with the shell of described drive motor, two described bearing carrier rings are contained in the middle part of described steering shaft, and are arranged on described chassis.
Particularly, the top of described steering shaft is provided with angular transducer.
The beneficial effects of the utility model are:
The utility model is a kind of highway and railway double duty tractor of energy pivot turn, each tire can both freely rotate, adopt four frequency converters to control separately corresponding drive motor, drive motor is controlled the rotating speed of corresponding tire, according to the speed discrepancy between different kinds of tyre, can easily control the rotation direction of each tire, realization is turned around, of the present utility model easy to operate, and the required space of turning around and commutate is all less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the generalized section of wheel word in Fig. 1;
Fig. 3 is the stressed schematic diagram of the utility model four described tires when spot turn;
Fig. 4 is the fundamental diagram of embodiment in the utility model.
In figure: 1-chassis, 2-drive motor, 3-tire, 4-frequency converter, 5-angular transducer, 6-bearing, 7-steering shaft, 8-L type support plate, 9-drive shaft.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model is a kind of highway and railway double duty tractor of energy pivot turn, comprise chassis 1, four drive motor 2, four tires 3, four frequency converters 4 and four wheel words, one end of wheel word is fixedly connected with the shell of drive motor 2, the drive shaft 9 of drive motor 2 is in transmission connection with tire 3, and the control signal mouth of frequency converter 4 connects with the control signal input end of corresponding drive motor 2 respectively.
Wheel word comprises steering shaft 7, two bearings 6 and L-type support plates 8, steering shaft 7 vertically arranges through chassis 1, the bottom of steering shaft 7 is fixedly connected with the horizontal ends of L-type support plate 8, the vertical end of L-type support plate 8 is fixedly connected with the shell of drive motor 2, two bearings 6 are sleeved on the middle part of steering shaft 7, and are arranged on chassis 1.The top of steering shaft 7 is provided with angular transducer 5.
As shown in Figure 3, when tractor truck need to be reversed end for end, rotating speed by 4 pairs of corresponding drive motor 2 of frequency converter is controlled, in the process of turning around, the first tire is subject to frictional ground force f1, and F1 method and the F1 that can be decomposed into as shown in the figure cut two application forces, and its excess-three wheel is stressed, and the rest may be inferred, F1 method and F3 method, the equal and opposite in direction of F2 method and F4 method, opposite direction, so these two pairs of power to make a concerted effort be zero.Remaining F1 cuts with F3 and cuts, and F2 cuts with F4 and cuts and formed two pairs of couples centered by the center of circle, so tractor truck take car body center as the center of circle, original place rotation, and turn radius is 0, has realized the pivot stud in minimum zone, simple to operation.
In the process of travelling, tire 3 is parallel with tractor truck car body direction, and by controlling the rotative speed of car body both sides drive motor 2, the velocity contrast that generation both sides tire 3 travels is controlled tractor truck service direction.
As shown in Figure 4, for example, when tractor truck is wanted to travel direction left driving, only need to reduce by 3 operations of left side tire, accelerate right side tire 3 running velocitys, just can make the deflection to the left of tractor truck travel direction.
