Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Example 1
The invention will be further described with reference to the accompanying drawings 1-3, in which the tire for a dual-purpose traction railway vehicle shown in fig. 1 is:
the tire for the rail and road dual-purpose tractor is a solid tire (high-load rubber solid tire, the outer diameter is 1060mm) with the width of 350mm, as shown in the attached drawing 1, the tire comprises a rim contact surface 1 and an outer tread 2, the longitudinal sections of the rim contact surface 1 (the diameter is 700mm) and the outer tread 2 are both circular, the outer tread 2 comprises an outer tread 21, an inner tread and a longitudinal groove 24, and the inner tread consists of a straight running friction surface 23 (the width is 116mm) and a turning friction surface 22; the tread band 2 is plain except for the longitudinal grooves 24, as shown in figure 3.
The transverse width (116mm) of the straight friction surface 23 is larger than the width (70 mm) of the upper surface of the steel rail, and the straight friction surface is always in friction contact with the upper surface of the steel rail in the process that the traction engine moves on the steel rail in a straight mode.
The tire for the track dual-purpose traction locomotive is a solid tire, the solid tire is long in service life and low in deformation rate, the maintenance cost of the vehicle is reduced, and the comfort of a driver is improved.
When the vehicle runs on the steel rail in a straight line, only the straight running friction surface 23 rubs with the upper surface of the steel rail; when the tire runs on a curve on a steel rail, the straight running friction surface 23 and the turning friction surface 22 rub against the upper surface of the steel rail, so that the inner side tread of the tire is in frictional contact with the steel rail in a railway running state, and the problem that full wheel drive cannot be realized due to small width and small friction area of the tire is avoided.
The friction coefficient of the steel rail and the rubber tire is much larger than that of the steel rail and the steel train wheel, so that the friction force between the steel rail and the rubber tire needs to be fully utilized to improve the traction force, no patterns are arranged on the tread surface 2 except for the longitudinal grooves 24, the contact area between the rubber tire and the steel rail can be increased to the maximum extent, the friction force is increased, the larger traction force can be realized under the condition that the power of an engine is not changed, and the energy consumption is reduced.
The outer tread 21 has two (60 mm each in width), one on each side of the inner tread, and between the outer tread 21 and the inner tread are longitudinal grooves 24.
The turning friction surfaces 22 are two (47 mm in width) and are respectively arranged on two sides of the straight friction surface 23.
The side surface of the tire for the rail and road dual-purpose tractor comprises an inner plane 3 (with an outer diameter of 880mm), an outer plane 4 (with an outer diameter of 1060mm) and a bending plane 5 (with a bending radius of 5 mm).
The inner plane 3 is contacted with the rim contact surface 1, the outer plane 4 is contacted with the outer tread 2, and the intersection of the inner plane 3 and the outer plane 4 is a bending plane 5, as shown in the attached figures 1 and 2.
Two outside treads only when the tractor is traveling on the road surface with road surface contact friction, two outside treads + inboard tread make the tire have great width, travel more steadily on the road surface. The longitudinal grooves 24 in the tread 2 increase the drainage and grip of the tire.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes to be applied in other fields, but all the technical matters of the present invention are not departed from the technical contents of the present invention, and any simple modification and equivalent changes made to the above embodiments according to the technical matters of the present invention still belong to the protection scope of the technical solution of the present invention.
