Title:
MOTORCYCLE REAR WHEEL SET LIFTING FRAME
Document Type and Number:
WIPO Patent Application WO/2021/012618
Kind Code:
A1
Abstract:
A motorcycle rear wheel set lifting frame, comprising: a rack (1) with a U-shaped structure and disposed symmetrically to the motorcycle rear wheel set (9); a bearing set (2) horizontally disposed above the rack (1) and located on one side of the motorcycle rear wheel set (9), the distance between the bearing set (2) and the rack (1) being greater than the maximum outer diameter of the motorcycle rear wheel set (9), and being able to be rotatably plugged in an hollow shaft of the motorcycle rear wheel set (9) in a cooperating manner when the motorcycle rear wheel set (9) is lifted; a lifting arm (3) with one end being connected with the rack (1) and the other end being connected with the bearing set (2); and a roller (4) symmetrically arranged at two ends of the rack (1), the axis of the roller (4) being parallel with that of the motorcycle rear wheel set (9). With adoption of the described structure, the lifting frame can realize lifting of the motorcycle rear wheel set (9) from the ground by means of single-person operation during the parking or repair of the motorcycle. In this way, the existing inclining status is changed into an erect status, thereby ultimately reducing the probability of rotating shaft deformation of the motorcycle rear wheel set (9) and the dissymmetrical abrasion on the tire surface.
