Abstract

The invention belongs to the technical field of speed change devices, and in particular relates to a transmission wheel and a transmission mechanism. Orientation arrangement, wherein each wheel assembly is movably connected with the wheel frame, and each wheel assembly can synchronously move towards or away from the axis of the wheel frame to change the radius of the transmission wheel. According to the transmission wheel of the embodiment of the invention, the wheel assembly and the wheel frame are movably connected. By applying an external force to the wheel assembly, the radius of the circumference where the transmission wheel and the transmission belt are formed by the plurality of wheel assemblies changes, and the wheel assembly The position determines the size of the radius, and the size of the radius determines the size of the transmission ratio, so as to realize stepless speed change.

Description

technical field [0001] The invention belongs to the technical field of speed change devices, and in particular relates to a transmission wheel and a transmission mechanism. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Continuously variable transmission, its English full name is Continuously Variable Transmission, referred to as CVT, refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. [0004] At present, the speed change of CVT is mainly by moving the side wings of the V-shaped pulley to squeeze the transmission belt, forcing the transmission radius of the driving and driven wheels to change so as to realize the change of the transmission ratio. This method requires a large axial pressure, and the extrusion contact between metals is easy to cause The deformation of the transmission belt or excessive we...
