Abstract

The invention discloses a distributed hub driving electric car chassis structure. The structure mainly comprises a hub driving and braking integrated system, a hub brake system, a rear steering system, a back suspension system, a front steering system, a front suspension system and a car frame. The hub motor is installed inside a wheel, the motor rotor part and the brake system are connected through a bolt, the brake system is connected with a steering pull rod of the steering system and a supporting shaft of the suspension system through a knuckle, the front suspension is connected with the car frame through an A-shaped arm, and the rear suspension is in rigid connection with the car frame through an upper base of a damping spring. The chassis adopts a four-wheel steering structure, the rear wheel adopts electric assistance independent steering, the front suspension adopts a MacPhersan type independent suspension, and the rear suspension adopts a dragging arm type independent suspension.

Description

technical field [0001] The invention belongs to the field of chassis design of wheel hub electric vehicles, and relates to a novel chassis structure of distributed wheel hub electric vehicles. Background technique [0002] As the problem of environmental pollution becomes more and more severe, people have higher and higher requirements on automobile exhaust emissions, so new energy vehicles will be the development trend of the future automobile field. Electric vehicles are the main members of new energy vehicles, and electric vehicles driven by distributed in-wheel motors are one of the main directions of electric vehicle research. Due to the great difference in structure and overall layout between distributed in-wheel electric vehicles and traditional electric vehicles, the chassis structure of traditional electric vehicles contains structures such as electric motors, differentials, reducers, and transmission shafts. Differentials, reducers and other structures reduce the ...
