Vehicles with this structure can only carry a single execution module and have poor scalability; and when a system fails, the entire vehicle needs to be shut down for maintenance. There are disadvantages such as long downtime and inconvenient maintenance.

[0006] The multi-link coupled action system 5 includes a balancing elbow 18 and a spring shock absorber; the lower part of each balancing elbow 18 is connected to a road wheel, and the ends of two adjacent balancing elbows 18 are connected head to tail through a spring shock absorber; the upper end of the balancing elbow 18 located at the front end is connected to the auxiliary wheel, and the lower end of the balancing elbow 18 located at the rear end is hinged to the drive unit bracket through the spring shock absorber, and the front bending part of each balancing elbow 18 is connected to the drive unit bracket through the road wheel pin.

[0007] Beneficial effects: The modularized and highly integrated present invention integrates power batteries, electric drive wheels, cooling systems, multi-link coupling suspensions, road wheels, remote control systems, etc. on the inner side of the track to form an independent drive unit, which has the characteristics of remote control, autonomous navigation positioning, trajectory planning and tracking, and is designed with external connection interfaces. The drive unit can be used independently, or multiple units can be flexibly combined to achieve rapid combination of two or more drive units. Each drive unit is mutually controlled as a master and a slave, which improves the maneuverability of the vehicle and its adaptability to multiple road conditions.

DETAILED DESCRIPTION

[0013] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below.

[0014] The invention proposes a highly integrated crawler independent drive unit structure, comprising a drive unit bracket 1, an integrated electric drive wheel 2, an electrical system 3, a power supply 4, a multi-link coupling action system 5, a remote control system 6, and a crawler 7;

[0015] The drive unit bracket 1 is mainly composed of a skirt plate 9, a rectangular tube 10, an electrical system mounting plate 11, a remote control system mounting plate 12, and a motor mounting attachment 13, which are connected into a frame by welding. The power supply 4 is installed on the inner side of the skirt plate 9, and the electrical system 3 and the remote control system 6 are respectively installed on the electrical system mounting plate 11 and the remote control system mounting plate 12. The integrated electric drive wheel 2 is connected to the front end of the drive unit bracket 1 through the motor mounting attachment 13. The load-bearing wheel shaft 14 connects the balance elbow 18 of the multi-link coupling action system 5, the load-bearing wheel 15, and the drive unit bracket 1 to form a complete drive unit. The tensioner 16 is connected to the rear end of the skirt plate 9 by bolts, and finally the track 7 is installed, and the track 7 is tightened by the tensioner 16.

[0016] The multi-link coupled action system 5 includes a balancing elbow 18 and a spring shock absorber; the lower part of each balancing elbow 18 is connected to a road wheel, and the ends of two adjacent balancing elbows 18 are connected head to tail through a spring shock absorber; the upper end of the balancing elbow 18 located at the front end is connected to the auxiliary wheel, and the lower end of the balancing elbow 18 located at the rear end is hinged to the drive unit bracket through the spring shock absorber, and the front bending part of each balancing elbow 18 is connected to the drive unit bracket through the road wheel pin.

[0017] Working principle:

[0018] The power source 4 and the integrated electric drive wheel 2 are connected through the electrical system 3 and the cable, and the power source 4 transmits power to the integrated electric drive wheel 2 (the electric wheel and the driving wheel are integrated), forcing the integrated electric drive wheel 2 to rotate, thereby driving the track 7 to rotate around the drive unit bracket 1, and at the same time the track rubs against the ground to realize the independent walking of the drive unit. The multi-link coupling action system 5 can achieve the passability and adaptability of various road surfaces, forming a lever mechanism with the road wheel pin 17 as the fulcrum, and cooperates with the spring shock absorber 21 to form an organic whole. When driving on a rough road surface and being acted upon by external force, each wheel can realize the function of independent bouncing, effectively improving the wheel's grip, thereby improving the vehicle's passability and adaptability to various road surfaces. The remote control system 6 is the command processing system of the drive unit. The drive unit can be used independently or in groups through the pull rod 8. It can be equipped with a remote-controlled weapon station and a UAV to achieve long-range air-to-ground joint operations and form a powerful fire support and strike. It can also be equipped with a mechanical arm, explosion-proof tanks, and rescue equipment to enter the threat area and complete tasks such as mine sweeping, bomb disposal, emergency rescue, and disaster relief in an unmanned environment.

[0019] The present invention integrates power batteries, electric drive wheels, cooling systems, multi-link coupling suspensions, road wheels, remote control systems, etc. on the inner side of the crawler to form an independent structure, which has the characteristics of remote control, autonomous navigation positioning, trajectory planning and tracking. The drive unit can be used independently, or multiple units can be flexibly combined. It has the advantages of fast replacement and fast maintenance. At the same time, the platform has strong expandability and is equipped with different execution modules to complete tasks such as wartime fire support strikes, unmanned reconnaissance, unmanned bomb disposal, emergency rescue, disaster relief, etc.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
