Problems solved by technology

At present, ordinary motorcycles (underbone bikes and knight bikes) on the market must manually shift gears when riding, so that the driving maneuverability needs to be judged subjectively by humans when shifting gears, and it requires considerable coordination of hands and feet to shift gears smoothly. , there are certain difficulties for most women or inexperienced drivers; the existing centrifugal continuously variable transmission (CVT) motorcycles do not require manual shifting when riding, but there are also low transmission efficiency and fuel consumption. High efficiency, high cost and price; the automatic transmission mechanism using planetary gear transmission has been applied to automobiles, but due to reasons such as cost, process and volume, it has not yet been applied to conventional motorcycles

Embodiment 1

[0032] Embodiment 1: The system includes an automatic transmission control unit, an electric shift actuator, a throttle control and an execution unit;

[0033] Among them, the electric shift actuator: includes a shift motor, a reduction gear and a shift shaft, and the shift motor drives the shift shaft to perform shift operations through the transmission of the reduction gear and the sector gear on the shift shaft;

[0034] Throttle control and execution unit: control the throttle to open and close;

[0035] Automatic transmission control unit: controls the electric shift actuator to perform shift operation. Before the shift operation is performed, the throttle control and execution unit receives the oil return command and reduces the throttle opening, thereby reducing the engine speed to reduce the shift speed. Shock; after the gear shift, if the gear increases, increase the throttle opening; if the gear decreases, decrease the throttle opening.

[0036] The system also incl...

Embodiment 2

[0043] Embodiment 2: as image 3 and Figure 4 As shown, the difference from Embodiment 1 is that a determination unit is provided on the side of the sector gear, and the determination unit determines whether the sector gear rotates in place, so as to increase the accuracy of gear shifting. The insulating case 1-1 of the judging unit is fixed on the base 1-12. There is a cavity inside the insulating case, the upper end has an opening, and a metal inner wall 1-6 is arranged in the cavity, and the convex moving contact is set in the insulating case. , The lower part of the convex moving contact is larger than the upper opening of the insulating shell, so that the moving contact is stuck in the cavity, and there is a spring 1-2 between the moving contact and the base. The spring 1-2 is in contact with the first moving contact 1-3 and the second moving contact 1-4, and can be compressed with the movement of the first moving contact 1-3 and the second moving contact 1-4, To ensur...

Embodiment 3

[0050] Embodiment 3: as Figure 5 As shown, the difference from Embodiment 2 is that the positions of the first insulating contacts 1-8 and the fourth insulating contacts 1-11 are different.

[0051] In the case of (1), the output potential signal is .

[0052] In the case of (2), the output potential signal is .

[0053] In the case of (3), the output potential signal is .

Abstract

The invention discloses an automatic variable speed control system for a motorcycle. The system comprises an automatic variable speed control unit, an electric gear shifting actuator and a throttle control and execution unit, wherein the electric gear shifting actuator comprises a gear shifting motor, a reducing gear and a variable-speed shaft, the gear shifting motor drives the variable-speed shaft to execute a gear shifting operation by virtue of transmission of a sector gear on the variable-speed shaft and the reducing gear; the throttle control and execution unit controls a throttle to close and open; the automatic variable-speed control unit controls the electric gear shifting actuator to execute a gear shifting operation, the throttle control and execution unit receives an oil return instruction before the gear shifting operation is executed, and the opening degree of a throttle is reduced, thus rotating speed of an engine is reduced to reduce gear shifting and speed changing impact; after the gear shifting operation is finished, the opening degree of the throttle is adjusted according to gear condition. The automatic variable speed control system disclosed by the invention has the advantages that the original structure of a common motorcycle engine is used effectively so that the motorcycle engine has an automatic gear shifting function, the overall structure is simple and compact, and arrangement is reasonable. The automatic variable speed control system disclosed by the invention keeps the advantages of high efficiency and low cost of the original motorcycle.

Description

technical field [0001] The invention relates to an automatic variable speed control system of a motorcycle. Background technique [0002] With the development of motorcycle technology, users have put forward higher requirements for the motorcycle itself, hoping that the motorcycle should not only be easy to drive and operate, but also energy-saving, environmentally friendly and fuel-efficient. At present, ordinary motorcycles (underbone bikes and knight bikes) on the market must manually shift gears when riding, so that the driving maneuverability needs to be judged subjectively by humans when shifting gears, and it requires considerable coordination of hands and feet to shift gears smoothly. , there are certain difficulties for most women or inexperienced drivers; the existing centrifugal continuously variable transmission (CVT) motorcycles do not require manual shifting when riding, but there are also low transmission efficiency and fuel consumption. High efficiency, high...
