Problems solved by technology

However, semi-trailers usually need to be towed by a tractor, which brings the following problems: First, the stacked body of the tractor and semi-trailer is too long, the turning diameter is large, and the passability is poor. It is difficult to complete the scheduled transportation and transfer tasks when the work area is not sufficient; Second, with the addition of a tractor, the weight of the whole vehicle is large, and it is easy to exceed the load limit of bridges, etc.

Embodiment Construction

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a self-propelled semi-trailer, which includes: a vehicle frame 1, a driving wheel mechanism 2 for driving the semi-trailer 1 to turn, lift and walk, and a driven wheel for supporting the semi-trailer 1 The mechanism 3, the driving wheel mechanism 2 and the driven wheel mechanism 3 are installed on the front side and the rear side of the vehicle frame 1 respectively.

[0031] The beneficial effects of the present invention are: by designing the semi-trailer with the drive wheel mechanism, the semi-trailer can turn and walk without a tractor, shorten the length of the vehicle body, reduce the turning radius, and improve the passage of t...

Abstract

The invention provides a self-propelled semitrailer and a vehicle. The semitrailer comprises a frame, a driving wheel mechanism used for driving the semitrailer to steer, ascend, descend and walk anda driven wheel mechanism used for supporting the semitrailer, and the driving wheel mechanism and the driven wheel mechanism are correspondingly installed on the front side and the rear side of the frame respectively. By designing the semitrailer with the driving wheel mechanism, the semitrailer can steer and walk without a tractor, the length of a semitrailer body is shortened, the turning radiusis reduced, the trafficability of the semitrailer is improved, and the weight of the semitrailer is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a self-propelled semi-trailer and a vehicle. Background technique [0002] Semi-trailer has the characteristics of heavy load, simple maintenance, and good economy. It is widely used in the road transportation industry for the transportation of large goods and equipment, and has a very important position in both military and civilian fields. However, semi-trailers usually need to be towed by a tractor, which brings the following problems: First, the stacked body of the tractor and semi-trailer is too long, the turning diameter is large, and the passability is poor. It is difficult to complete the scheduled transportation and transfer tasks when the work area is not sufficient; Second, with the addition of a tractor, the weight of the whole vehicle is large, and it is easy to exceed the load limit of bridges and the like. Contents of the invention [0003] The technic...
