Embodiment 1

[0015] The structure of a two-speed transmission mechanism for an electric motorcycle provided in this embodiment is shown in the figure.

[0016] The two-speed transmission mechanism of an electric motorcycle includes a driving gear 1 and an output gear 2 meshing with each other, and also includes a shifting gear 3 meshing with the output gear 2. The driving gear 1 is provided with a shift fork 31, and the shift fork 31 The rotation of the shift fork 31 is controlled by the driving gear 1. The other end of the shift fork 31 extends out of the drive gear 1 and extends into the limit groove 32. The rotation of the shift fork 31 is limited in the limit groove 32. When the motor rotates forward or reverse, The shift fork 31 rotates forward or reversely accordingly, and the driving gear 1 is moved to mesh with the output gear 2 or the shift gear 3 respectively.

[0017] Wherein, the number of teeth of the shift gear 3 is different from that of the output gear 2 .

[0018] This so...

Abstract

The invention discloses a two-gear speed change mechanism of an electric motorcycle and relates to the technical field of motorcycle driving mechanism structures. The two-gear speed change mechanism of the electric motorcycle comprises a driving gear, an output gear and a shifting gear which is meshed with the output gear, wherein the driving gear is meshed with the output gear, a shifting fork isarranged on the driving gear, the rotation of the shifting fork is controlled by the driving gear, and the other end of the shifting fork extends out of the driving gear and stretches into a limitinggroove; the shifting fork rotates and is limited in the limiting groove; when a motor rotates clockwise or anticlockwise, the shifting fork rotates clockwise or anticlockwise along with the shiftingfork, and the driving gear is toggled to be separately meshed with the output gear or the shifting gear. According to the scheme, the gear of the motorcycle can be adjusted, and the motorcycle can climb a slope more easily.

Description

technical field [0001] The invention relates to the technical field of motorcycle driving mechanism structure, in particular to a two-speed transmission mechanism of an electric motorcycle. Background technique [0002] like figure 1 Shown is a schematic diagram of the structure of the existing motorcycle drive mechanism, including a driving gear 1 and an output gear 2 meshing with each other, wherein the driving gear 1 is connected to the motor, and the output gear 2 is connected to the hub of the motorcycle. [0003] After electrification, the motor converts electrical energy into mechanical energy, and the driving gear 1 rotates, thereby driving the wheels to rotate and driving the vehicle forward. However, the speed of this mechanism is slow to ride, the climbing is weak, and the work efficiency is low, which reduces the service life of the battery and shortens the cruising range. Contents of the invention [0004] The technical problem to be solved by the present in...
