Problems solved by technology

However, due to the small size of the electric vehicle, the wheelbase of the vehicle is relatively small, which makes the electric vehicle prone to rollover due to the centrifugal force when turning at high speed, causing safety accidents
However, increasing the wheelbase will increase the volume of the car, which is not conducive to the parking of cars or the passage of narrow roads.

Abstract

The invention provides an automobile wheel tread adjusting device. The automobile wheel tread adjusting device comprises a rear suspension, a hub motor and a support. The support is fixed to a frame of an automobile. The rear suspension comprises a shock absorber and a longitudinal pull rod. The shock absorber is connected with the frame through the support, the longitudinal pull rod is connected with the frame, the hub motor is located inside a wheel, the wheel is connected with the rear suspension, a first bearing is arranged between the shock absorber and the support, a second bearing is arranged at the joint of the shock absorber and the longitudinal pull rod, the hub motor can drive the wheel to rotate around the axis of the support to make the wheel tread be switched between a stretching state and a shrinking state, and a limiting locking device is arranged on the rear suspension and used for fixing the wheel when the wheel rotates to the stretching position or the shrinking position. By the application of the bearings and the limiting locking device, the wheel tread can be changed through turnover of the hub motor.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile wheelbase adjusting device. Background technique [0002] With the development of the automobile industry, the energy problems and environmental problems it brings are increasingly affecting people's lives and become an important factor in the deterioration of people's living environment. Electric vehicles have become a solution to these problems due to their advantages in energy saving and environmental protection. An important direction of development. [0003] In addition to the advantages of energy saving and environmental protection, electric vehicles also have the characteristics of compactness and convenience. Compared with large-volume ordinary family cars, electric vehicles are less likely to be unable to park because the parking lot is too small. However, due to the small size of the electric vehicle, the wheelbase of the vehicle is relatively small, which make...
