Energy-saving automatic speed control system of light motorcycle

Abstract

The invention discloses an energy-saving automatic speed control system of a light motorcycle. The energy-saving automatic speed control system comprises a centrifugal fly-block type clutch, a primary reduction gear, a secondary reduction gear, an automatic variable speed control device and a rear shaft assembly. The centrifugal fly-block type clutch is mounted on an output shaft of an engine; the rear shaft assembly and the primary reduction gear are mounted on a frame; and the primary reduction gear is connected with the centrifugal fly-block type clutch. The secondary reduction gear comprises a secondary chain, a variable speed chain wheel set, a chain wheel hub and an intermediate chain wheel, wherein the variable speed chain wheel set is mounted on the right end of a rear shaft in the rear shaft assembly through the chain wheel hub; the intermediate chain wheel is mounted on the left end of an intermediate shaft of the primary reduction gear; and the secondary chain connects the variable speed chain wheel set and the intermediate chain wheel. The automatic variable speed control device comprises an electronic control unit, an accelerator switch sensor, an electric push rod, an electric push rod displacement sensor, a variable speed steel wire and a derailleur. The electronic control unit is respectively connected with a speed measuring device, the accelerator switch sensor, the electric push rod and the electric push rod displacement sensor by using wires.

Description

technical field [0001] The invention relates to a transmission system of a light motorcycle, more precisely, the invention relates to an energy-saving automatic transmission system of a light motorcycle. Background technique [0002] Today, the main form of transmission system in the motorcycle market is the gear type stepped transmission system. The gear-type stepped transmission system achieves the purpose of speed change by changing the meshing of different gear pairs in the gearbox. This variable speed system has been widely used because of its advantages, but there are still certain disadvantages. [0003] From the structural analysis, in the gear-type stepped transmission system, a pair of gears that mesh with each other is required for each gear, which makes the weight of the vehicle larger, the structure of the gearbox is complicated, the design is difficult, and the manufacturing accuracy is high. Costs rise. Moreover, when the engine transmits power to the rear ...

AI Technical Summary

Problems solved by technology

[0005] First, the labor intensity of the driver is relatively high

Every time you shift gears, you need to go through the operation of cutting off the accelerator-pulling the clutch-engaging gear-releasing the clutch-refueling, which not only easily causes driving fatigue, but also needs to divert the driver's attention, which is prone to accidents

[0006] Second, every shift requires an interruption of power

Different drivers are used to shifting gears at different engine speeds or vehicle speeds, and the economical working range of the engine is certain, which means that when driving at different vehicle speeds, the transmission ratio of the transmission device may not be able to make the driving resistance and the engine The most economical load - the speed range matches, and the engine's fuel-saving potential cannot be fully utilized

[0008] Fourth, additional kinetic energy is consumed by the power train when coasting on a cut-off

Therefore, this traditional transmission system cannot make good use of the inertia of the motorcycle for sliding, causing unnecessary wear and tear of parts and energy loss, and cannot meet the increasingly stringent energy-saving requirements of today's society.
