Abstract

The invention discloses a tricycle which comprises a main tricycle frame and two rear swing arms. A front wheel is installed on the main tricycle frame. Each rear swing arm is provided with a rear wheel. A middle shaft is arranged on the main tricycle frame and is parallel to the axial direction of the rear wheels. Each rear swing arm is rotationally arranged on the middle shaft in a sleeving mode. A deflection mechanism is installed between the main tricycle frame and the two rear swing arms. When the tricycle turns, the deflection mechanism makes the two rear swing arms deflect relative to the main tricycle frame, one of the rear swing arms moves upwards around the middle shaft relative to the main tricycle frame, and the other rear swing arm moves downwards around the middle shaft relative to the main tricycle frame. According to the tricycle, the two rear swing arms can deflect relative to the main tricycle frame under the action of the deflection mechanism, that is, the two rear swing arms swing in opposite directions relative to the main tricycle frame, thus, the effect that shafts of hubs of the two rear wheels are parallel completely in any motion mode is guaranteed, the effect that the three wheels are in contact with the ground all the time is guaranteed, the total contact area between tires and the ground is increased, the stable, comfortable and safe riding experience is provided, and riding is safer.

Description

technical field [0001] The invention relates to a tricycle. Background technique [0002] A tricycle includes a frame, a front wheel and two rear wheels. The frame includes a main frame and a rear rocker. The rear rocker is hinged to the main frame and the rear rocker can be moved up or down in the same direction relative to the main frame. Swing, when the tricycle of this structure is turning, the two rear wheels still run at the same height, and the overall frame is in a non-rolling state, which makes the centrifugal force and gravity of the vehicle and the occupant unable to balance when the tricycle is turning, and it is easy to sideways. Turning over or sliding sideways poses a safety hazard. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that when the current tricycle turns, the two rear wheels run at the same height, the whole frame is in a non-rolling state, it is easy to roll over, and the safety hazard i...
