Embodiment 1

[0031] This embodiment provides an independently driven all-wheel steering electrified unmanned vehicle chassis, such as Figure 1-3 As shown, the unmanned vehicle chassis includes: body frame system, circuit system, four wheels 1, each wheel 1 corresponds to a set of independent drive system 2, independent steering system 3, independent suspension system 4 and independent braking system.

[0032] Here, the wheel 1 is a wheel assembly, including a tire 12 , a rim 11 , a hub 10 and a steering column 9 .

[0033] The body frame system includes a vehicle frame 6 and a non-load-bearing body 5. The circuit system, four drive systems, four steering systems and four brake systems are fixedly installed on the vehicle frame 6, and each wheel 1 passes through a set of suspension The system is connected to the vehicle frame 6 .

[0034] Such as Figure 7 As shown, the drive system adopts an independent wheel motor drive system, including: a drive motor 22, a reducer 25 and a universal...

Embodiment 2

[0044] The difference from the above-mentioned embodiment 1 is that, in order to save space around the wheel and facilitate the design and shape of the car body, a reversing block is added to the traditional double-wishbone suspension system, specifically: the suspension system in this embodiment Includes: two wishbones, shock absorbers, pushrods and steering blocks. The reversing block is a triangular structure, and each of its three vertices is provided with a connection point (respectively designated as connection point A, connection point B and connection point C); both ends of the cross arm are equipped with rod end bearings, and the two cross arms One end of the cross arm is respectively connected to the steering column through bolts, and the other end of one of the cross arms is pinned to the connection point C on the reversing block, and the reversing block can rotate around the pin shaft at the connection point; The push rod lug is welded, one end of the push rod is c...

Abstract

The invention provides an all-wheel steering electric unmanned vehicle chassis which is independently driven. The chassis comprises a vehicle body frame system, a circuit system and four wheels. Eachwheel is independently driven, steered and braked by a corresponding driving system, a steering system and a braking system respectively. Each of the wheels is connected with the vehicle frame througha set of suspension systems; A vehicle body frame system includes a vehicle frame for providing mounting support for the drive system, steering system, suspension system, and brake system and a non-load bearing vehicle body enclosed outside the vehicle frame; The circuit system comprises a vehicle controller, a power supply unit and eight motor controllers. Each wheel of the chassis can be independently driven, braked and steered, and the driving, braking and steering are all controlled by wire, so that the chassis has high versatility.

Description

technical field [0001] The invention relates to a vehicle chassis, in particular to an independently driven all-wheel steering electrified unmanned vehicle chassis, which belongs to the field of vehicle chassis design. Background technique [0002] Unmanned vehicles are an important development direction in the field of civilian and military vehicles. They refer to vehicles that have autonomous behavior capabilities and completely omit human driving mechanisms. They have the characteristics of intelligence, wire control, and robotization. Operational tasks, including strike, combat, patrol, reconnaissance, logistics, transportation, ferry, distribution and other tasks, have broad application prospects in civilian or military fields. In my country's national strategies such as Made in China 2025, a new generation of artificial intelligence development plan, and a new generation of army equipment development, unmanned vehicles have become important development targets in the f...
