Embodiment 1

[0031] This embodiment provides an independently driven all-wheel steering electric unmanned vehicle chassis, such as Figure 1-3 As shown, the unmanned vehicle chassis includes: a body frame system, a 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 Brake system.

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

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

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

Embodiment 2

[0044] The difference from Embodiment 1 above is that in order to save wheel space 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 cross arms, shock absorber, push rod and reversing block. The reversing block has a triangular structure, and each of its three vertices is provided with a connection point (respectively called connection point A, connection point B and connection point C); both ends of the cross arm are equipped with rod end bearings, and two cross arms One end of the cross arm is connected to the steering column by bolts, and the other end of one of the cross arms is pin-connected to the connection point C on the reversing block, the reversing block can rotate around the pin at the connection point; the other cross arm Welded with push rod lugs, one end of the push rod is connected with the push rod lugs by bolt...

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 electric unmanned vehicle chassis, and belongs to the field of vehicle chassis design. Background technique [0002] At present, due to the frequent occurrence of traffic accidents and the rising labor costs, the market demand for unmanned vehicles is increasing, whether it is freight or passenger vehicles. However, the current invention patents related to unmanned vehicles mostly focus on algorithms such as sensors, environment perception, and path planning. The realization of specific real cars often depends on the transformation of passenger cars that have been mass-produced. However, this type of chassis often cannot be designed according to the characteristics of unmanned vehicles, the degree of wire control is low, and the transformation is more difficult. A large number of drivers and corresponding mechanical connection devices need to be install...
