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...
