The invention discloses an electric tricycle rear axle double-swing-arm suspension mechanism. The mechanism comprises a rear axle frame and two swing arms symmetrically arranged on two sides of the rear axle frame, wherein rear wheels are installed on the two swing arms respectively, a step shaft is arranged on the rear axle frame, each swing arm is rotatably arranged on the step shaft in a sleeving manner, a rotating mechanism is mounted between the rear axle frame and the two swing arms, when the electric tricycle turns, the rotating mechanism enables the two swing arms to deflect relative to the rear axle frame, one swing arm moves upwards around the step shaft relative to the rear axle frame, and the other swing arm moves downwards around the step shaft relative to the rear axle frame.The mechanism is advantaged in that the two swing arms can deflect up and down relative to the rear axle frame under the action of the rotating mechanism, so shafts of the two rear wheels are completely parallel, three wheels of the electric tricycle are always in contact with the ground, the total ground contact area of tires is increased, and stable, comfortable and safe driving experience is provided.
Description
technical field [0001] The invention belongs to the technical field of electric vehicle mechanical movement, and in particular relates to a rear axle double-swing arm suspension mechanism of a three-wheel electric vehicle.
