Description
Technical field
The present invention relates to a kind of telescopic driving wheel structures.More particularly to it a kind of applies in rail loading point weighing vehicle system
On telescopic driving wheel structure.
Background technique
Applying the mechanical trolley on railway on all kinds of tracks at present is travelled on accessible track, due to existing
Mechanical trolley in technology is limited by wheel, and cannot achieve evacuation when there is barrier on track, it is even more impossible to realize in train
Or the traveling that shuttles under the chassis of subway carries out safety check operation, this is because mechanical trolley in the prior art is in the design process
The width of wheelspan can not be changed, trolley can only be designed according to the developed width of track, and when the mechanical trolley encounters barrier
Wheel normally travel in body construction does not have contractile function, and mechanical trolley is caused to run on the railroad track very in this way
It is not convenient.
Summary of the invention
According to problem of the existing technology, the invention discloses a kind of telescopic driving wheel structure, specific structure includes:
Bearing block is provided with splined shaft and spring across bearing block, and one end of the splined shaft is connected with wheel, the splined shaft
The other end is connected on driven rod；One end of the spring is connect with bearing block, the other end is connected on driven rod, the transmission
Bar is connected with motive bearing, and the inside of the bearing block is arranged side by side there are two bearing, which also wraps
Anticollision wheel is included, bearing is fixedly connected on the anticollision wheel, the bearing is connected with one end of anti-collision bar resets, institute
The anti-collision bar resets other end is stated to be connected with bearing block.
The anticollision wheel is fixedly connected on bearing block by colliding axis.
By adopting the above-described technical solution, a kind of telescopic driving wheel structure provided by the invention, which is answered
It uses on the mechanical trolley run on track, so that mechanical trolley is shuttled under the chassis of subway traveling, actual travel process
In when anticollision wheel and train wheel contact, under the action of train wheel pressure, bullet inside compression contraction type driving wheel
Spring is shunk, and drives entire contraction type driving wheel to contract.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The some embodiments recorded in application, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of contraction type driving wheel in the present invention；
Fig. 2 is contraction type driving wheel structure sectional view in the present invention.
Specific embodiment
To keep technical solution of the present invention and advantage clearer, with reference to the attached drawing in the embodiment of the present invention, to this
Technical solution in inventive embodiments carries out clear and complete description:
A kind of telescopic driving wheel structure as Figure 1-Figure 2, specific structure include bearing block 50, pass through bearing block 50
It is provided with splined shaft 63 and spring 64.One end of the splined shaft 63 is connected with wheel 52, the other end of the splined shaft 63
It is connected on driven rod 54；One end of the spring 64 is connect with bearing block 50, the other end is connected on driven rod 54.It is described
Driven rod 54 is connected with motive bearing 53, and the inside of the bearing block 50 is arranged side by side, and there are two bearing 62, scalable drivings
Wheel construction further includes anticollision wheel 51, is fixedly connected with bearing I I61 on the anticollision wheel 51, the bearing I I61 with
One end of anti-collision bar resets 60 is connected, and 60 other end of anti-collision bar resets is connected with bearing block 50.Under working condition: when anti-
When collision wheel 51 and train wheel contact, under the action of train wheel pressure, the bullet inside contraction type driving wheel 11 is compressed
Spring 64 is shunk, to drive entire contraction type driving wheel to contract.
Further, anticollision wheel 51 is fixedly connected on bearing block 50 by colliding axis 60, is guaranteed in train wheel
When contact, trolley contact portion is not damaged, and reduce the frictional force with train wheel contact using anticollision wheel 51.
Further, car wheel 52 is connect with one end of splined shaft 63, and the one of 63 other end of splined shaft and driven rod 54
End connection, 54 other end of driven rod are connect with motive bearing 53, by this connection type, can transmit drive force to trolley vehicle
Wheel 52, while also achieving the contraction of car wheel 52.
A kind of telescopic driving wheel structure disclosed by the invention drives after anticollision wheel 51 touches train wheel
Spring realizes the automatic contraction of wheel, which can be applied to and be walked on mechanical trolley in orbit, guarantees
Mechanical trolley traveling accessible in orbit.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
