Embodiment 1

[0021] Such as Figure 1-4 As shown, a kind of unmanned vehicle comprises vehicle frame 1, and described vehicle frame 1 front portion is provided with two drive wheels 2, and described two drive wheels 2 are driven by respectively independent left drive motor 11 and right drive motor 12 Drive, the vehicle frame 1 rear portion is provided with at least one driven wheel 31, and described driven wheel 31 is universal wheel, through the setting of above-mentioned two drive motors and drive wheel, make above-mentioned each drive wheel all can realize self-rotation, And the speed of a driving wheel can be adjusted according to the steering angle, so that the steering of the unmanned vehicle can be realized through the difference in speed. At the midpoint, the in-situ steering can effectively improve the steering quality, and the setting of the driving wheel can increase the driving force of the unmanned vehicle, increase the output force, and improve the steering efficiency while i...

Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 is:

[0030] Such as Figure 4 As shown, a vertically arranged mechanical spring shock absorber 17 is respectively provided between the two ends of the rear swing arm 15 and the vehicle frame 1, and the vehicle frame 1 is provided with a connecting bar 18 extending downward. The rear swing arm 15 is connected to the connecting rod 18 through a pivot 181 to realize the rotational connection between the middle part of the rear swing arm 15 and the vehicle frame 1. The third beam 16 is provided with an upper ear body 161, and the rear swing arm 15 is provided with a lower ear body 151 on the side, and the upper and lower ends of the mechanical spring shock absorber 17 are hinged with the upper ear body 161 and the lower ear body 151 respectively. The left and right flips can be realized on the connecting bar, so as to realize the ups and downs adaptation to the wheels, and carry out stable and effective shock absorpt...

Abstract

The invention relates to an unmanned vehicle. The unmanned vehicle comprises two front wheels and two driving modules of which the output shafts are coaxially connected with the front wheels; an electric control cabinet is arranged above the driving modules; a suspension is fixedly arranged at the top of the electric control cabinet; two universal wheels located behind the front wheels are arranged under the rear end of the suspension; and the diameter of the front wheels is larger than that of the universal wheels. The unmanned vehicle of the invention has the advantages of smaller steering radius, capability of realizing central steering and high steering efficiency. The stability of the body of the unmanned vehicle can be kept when the unmanned vehicle passes an obstacle.

Description

technical field [0001] The invention relates to an unmanned vehicle and belongs to the technical field of unmanned vehicles. Background technique [0002] In the current society, the use of unmanned vehicles has gradually become popular. Unmanned vehicles are widely used in transportation and logistics. When transporting goods, it is usually necessary to set various routes. Obstacles are detected, so as to automatically turn and avoid obstacles. [0003] When an unmanned vehicle turns during driving, it usually uses the motor to drive the rotation differential of the tires to realize the steering of the unmanned vehicle, while the general all-wheel steering vehicle adopts a set of steering actuators at the front and rear, and a pull rod in the middle Link, or use two independent steering units, operated by a motor-driven linkage. However, the above-mentioned device can only achieve a smaller turning radius. Due to structural limitations, it is impossible to realize center ...
