With this structure of the shift control mechanism, since the shift pedal installation shaft 2 is separated from the transmission rod installation shaft 3, the transmission efficiency of the shift torque is low when shifting gears, and the shift torque decreases when it is transmitted to the transmission rod installation shaft 3 , so that the driver needs to use more force when shifting gears to achieve the required shifting torque, which increases the difficulty of manipulation; and the two installation shafts are respectively welded on the shift pedal 1, and the shift pedal 1 not only needs to increase the surface area , increase the cost of surface treatment, and more seriously, destroy the integrity of the shift control mechanism and reduce the structural strength

Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0017] Such as image 3 , Figure 4 As shown, the present invention is mainly composed of a shift pedal 1, a shift pedal shaft 2, a first adapter 4, a transmission rod 5 and a second adapter 6, wherein the shift pedal shaft 2 is welded and fixed on the shift pedal 1 The middle part of the shift pedal shaft 2 is installed on the front left footrest mounting bracket 10 through the positioning sleeve 9, and the front end of the shift pedal shaft 2 is provided with an external spline to connect with the spline hole 4b provided by the adapter 4 . The first adapter joint 4 is a universal joint, composed of a spline seat 4a provided with a spline hole 4b and a ball seat 4f provided with a threaded hole, as Figure 5 , Figure 6 As shown, the middle part of the spline seat 4a is provided with a toggle arm 4c, and the end of the toggle arm 4c is provided with a ba...

The invention relates to a motorcycle pedaling and gear-shifting device, which comprises a gear-shifting pedal (1) and a drive rod (5), wherein one end of the gear-shifting pedal (1) is fixed with a gear-shifting pedal shaft (2); and the drive rod (5) is connected with an adapter coupling (4). The device is characterized in that one end of the gear-shifting pedal shaft (2) is connected with the gear-shifting pedal (1), while the other end is connected with the first adapter coupling (4) through a spline. The device combines a mounting shaft of the gear-shifting pedal and a mounting shaft of the drive rod into a whole to make the gear-shifting pedal have a compact structure, improves the gear-shifting torque transmitting efficiency and improves the whole structure strength of a gear-shifting operating mechanism so as to realize labor conservation and comfort during gear shifting. Because the structure is simpler and the dimension volume is smaller, the materials are saved, the manufacturing process is simplified, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to a shifting control mechanism, in particular to a motorcycle pedal shifting control device. Background technique [0002] The motorcycle shift mechanism is a structural component used to shift gears when the motorcycle is running. Its manipulation methods include foot manipulation and hand manipulation, as well as mechanical and electric. There is a traditional foot-operated mechanical shift mechanism (such as figure 1 , figure 2 As shown), the shift pedal 1 is installed on the front left footrest installation bracket through the shift pedal installation shaft 2 fixed at one end, and a transmission rod is installed beside the shift pedal installation shaft 2 on the shift pedal 1. Shaft 3, the transmission rod installation shaft 3 is connected with the transmission rod 5 through the adapter joint 4. With this structure of the shift control mechanism, since the shift pedal installation shaft 2 is separated from the transmissio...
