摘要： A transmission is disclosed which comprises a rotatable transmission shaft defining a shaft space therein, and a gear mounted coaxially with the transmission shaft for rotation around the transmission shaft. A meshing component is mounted on the transmission shaft for movement in a radial direction between a disengaged position and an engaged position. In the disengaged position the meshing component does not mesh with the gear such that the gear is rotatable around the transmission shaft. In the engaged position the meshing component meshes with the gear such that the gear rotates with the transmission shaft. A cam and an electric gear shift motor are each mounted in the shaft space and for rotation with and relative to the transmission shaft. The cam has at least one lobe extending therefrom in the radial direction. The at least one lobe moves relative to the meshing component upon rotation of the cam relative to the transmission shaft. The electric gear shift motor is mechanically coupled to the cam whereby operation of the electric gear shift motor rotates the cam relative to the transmission shaft to cause the at least one lobe to bear against the meshing component and thereby move the meshing component between the disengaged and engaged positions.
