Electric speed adjustment device of continuously variable transmission for electrically adjusting reducing of driving wheel and method of electric speed adjustment device

Abstract

The invention relates to the technical field of speed change of mobility scooters, and discloses an electric speed adjustment device of a continuously variable transmission for electrically adjusting the reducing of a driving wheel and a method of the electric speed adjustment device. The electric speed adjustment device for the reducing of the driving wheel adopted by the method comprises an adjustment motor rotating forwards or backwards, a reducing gear set and a transmission controller; wherein the adjustment motor is connected with a spiral thrust device through the reducing gear set, and is electrically connected with the transmission controller through a wire. The motor vehicle electric control continuously variable transmission consisting of the electric speed adjustment device can meet the requirements of fuel and electric mobility scooters on high-speed driving and low-speed climbing, and the electric speed adjustment device can control speed ratio change of the driving wheel and a driven wheel to complete acceleration and reduction of electric control speed change, and is simple in structure, convenient to operate, low in production cost, and easy to spread and popularize.

Description

[0001] technical field [0002] The invention relates to the technical field of speed change devices for power vehicles, in particular to an electric speed control device and method for electrically adjusting the diameter reduction of a driving wheel of a continuously variable transmission. Background technique [0003] At present, fuel-powered scooters or electric scooters are generally used as transportation vehicles, and the current fuel-powered scooters usually have two types of gear shifting: one is manual gear shifting, and the pedal clutch needs to be used to cut off the power when changing gears. Only when shifting gears can be performed, there are frequent shifting and difficult operation; the other is advanced automatic shifting, which is convenient for shifting operations, but the price is high. The current variable speed of electric scooter is usually: one is directly driven by electric motor, and the electric motor works in the low-efficiency area when startin...

AI Technical Summary

Problems solved by technology

[0003] At present, fuel scooters or electric scooters are generally used as vehicles for transportation, and the current fuel scooters usually have two types of gear shifting: one is manual shifting , then the power needs to be cut off by the foot clutch when shifting gears, so that the gears can be shifted frequently, and the operation is difficult; the other is advanced automatic gear shifting, which is easy to operate, but the price is high

The current variable speed of electric scooter is usually: one is directly driven by electric motor, and the electric motor works in the low-efficiency area when starting or climbing, and the output current is large, which will consume more energy and affect the cruising range and service life of the battery.

Another is that the motor is driven by the deceleration form of a reduction box, which solves the drive when starting or climbing, but there is an electric scooter that always works at a low speed and loses the driving speed; there is also a power output by the motor. Reduction Gearbox Shifting Variable Speed ​​Drive Vehicle

There are frequent manual shifting and difficult operation, which cannot satisfy automatic shifting. It is necessary to ensure a certain amount of traction when starting and climbing, and to ensure that a certain speed can be achieved when driving on flat roads, that is, low torque at high speed and high torque at low speed. There is no automatic trade-off between them, often because the driving speed is taken care of but part of the climbing ability is lost
