Abstract

The invention discloses a rear suspension assembly of an electric tricycle vehicle. The rear suspension assembly comprises a rear axle frame and two swing arms symmetrically arranged on the two sidesof the rear axle frame, and rear wheels are installed on the two swing arms respectively. A step shaft is arranged on the rear axle frame, the step shaft is parallel to the axis of an axle of a rear wheel, and the swing arms are rotatably arranged on the step shaft in a sleeving mode; and eccentric arms extending in opposite directions are arranged on the two swing arms, the free ends of the two eccentric arms are hinged to two pushing arms through first pivots respectively, the free ends of the two pushing arms are connected to a second pivot, and the two ends of the second pivot are connected together through a rotating mechanism. Under the combined action of the eccentric arms, the first pivots, the second pivot and the rotating mechanism, the two swing arms swing upwards and downwardsrelative to the rear axle frame, so when the electric tricycle turns, axles of the two rear wheels can be completely parallel, centrifugal force caused by turning is offset, and driving safety is improved.

Description
