Abstract

The invention belongs to the technical field of four-wheel recreational scooter, and provides a four-wheel electric vehicle independent suspension. The four-wheel electric vehicle independent suspension is provided with a left cross arm and a right cross arm, and the left cross arm and the right cross arm are connected into a whole through a transverse stabilizer bar connected to an auxiliary frame; the two ends of the transverse stabilizer are connected with a left damper and a right damper through a left connecting rod and a right connecting rod respectively; the independent suspension is further provided with a left adjusting arm and a right adjusting arm; the left cross arm and the left adjusting arm are connected with the left damper and the auxiliary frame, and a left longitudinal arm connected with the frame into a whole is connected to the left brake; the left brake is connected with the frame through the left damper; the right cross arm and the right adjusting arm are connected with a right brake and the auxiliary frame, and a right longitudinal arm connected with the frame into a whole is connected to the right brake; the right brake is connected with the frame into a whole through the right damper. Accordingly, mutual rigid contact is avoided, noise is reduced, and the service life of parts is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric four-wheel scooter, and mainly provides an independent suspension for the rear suspension of the four-wheel electric vehicle. Background technique [0002] The rear suspension is the assembly of all force transmission link devices between the frame of the car and the axle or wheels. Its function is to transmit the force and moment between the wheels and the frame, and the buffer is transmitted to the frame from the uneven road surface. Or the impact force of the car body, and attenuate the vibration caused by it, so as to ensure the smooth driving of the car. So far, the known four-wheel electric vehicle rear suspension is a rear axle or torsion beam type non-independent suspension. Based on this structure, the following problems are caused: [0003] 1. When the left and right wheels are bouncing, they will be involved with each other, which will reduce the comfort of the ride and the safety of ...
