Embodiment Construction
[0028] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] In order to achieve the purpose of the present invention, as Figure 1 to Figure 2 As shown, a shifting device is provided in one of the embodiments of the present invention, comprising:
[0030] central axis 10;
[0031] The shift shaft 20 is provided with three installation grooves on its circumferential surface, and its axis is arranged parallel to the axis of the central shaft 10;
[0032] The four shift transmission wheel sets include the shift driving wheel 21 and the shift passive wheel 11. The shift driving wheel 21 is sleeved on the shift shaft 20 and its inner hole is uniformly provided with nine arc-shaped grooves along the circumferential direction. The shifting passive wheel 11 is sheathed and fixedly connected to the central shaft 10, and the shifting passive wheel 11 is also connected to the shifting driving wheel 21; ...

The invention discloses a gear shifting device and a vehicle with the same. The gear shifting device comprises a central shaft, a gear shifting shaft, a gear shifting transmission wheel group, gear shifting connecting pieces and a gear poking rod, wherein mounting grooves are formed in the circumferential surface of the gear shifting shaft; the gear shifting transmission wheel group comprises a driving gear shifting wheel and a driven gear shifting wheel; the driving gear shifting wheel sleeves the gear shifting shaft, and arc-shaped grooves are uniformly formed in an inner hole of the driving gear shifting wheel; the driven gear shifting wheel sleeves the central shaft, is fixedly connected to the central shaft and is further connected with the driving gear shifting wheel; each gear shifting connecting piece penetrates into the corresponding mounting groove; an annular lug is arranged on the circumferential surface of the gear poking rod. According to the gear shifting device, the gear poking rod moves to a joint of the driving gear shifting wheel and the gear shifting shaft; the annular lug pushes out the gear shifting connecting pieces, so that the gear shifting connecting pieces are protruded out of the circumferential surface of the gear shifting shaft and are clamped with the arc-shaped grooves of the driving gear shifting wheel, the gear shifting shaft is locked with the driving gear shifting wheel and transfers torque to the driving gear shifting wheel, and gears are shifted; in the stationary and running states of the vehicle, high-speed-ratio smooth gear shifting can be realized by moving the gear poking rod, the vehicle is convenient to start, and time and labor are more saved.
Description
technical field [0001] The invention belongs to the technical field of vehicle drive, and in particular relates to a shifting device and a vehicle thereof. Background technique [0002] A bicycle is a means of transportation in people's daily life, and usually has at least one speed change device, which is used for shift control of vehicle running. [0003] In the known prior art, the bicycle generally adopts the tower wheel for gear shifting operation, which can only shift gears during rotation and can only shift gears one by one, which is time-consuming and laborious, and is not convenient for riding. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a gear shifting device and a vehicle thereof. [0005] In order to achieve the above object, technical scheme of the present invention is as follows: [0006] Gear shifter, including: [0007] The central axis; [0008] The shift shaft is provided with at le...
