Abstract

The invention relates to a speed limiting device of a household electric bicycle. The speed limiting device of the household electric bicycle comprises a fixed outer drum and a rotating part consisting of four same steel balls corresponding to four same springs and a center shaft, and is characterized in that the four same springs are respectively fixed to a cross-shaped rotating frame on the periphery of the center shaft positioned in the fixed outer drum; the four same steel balls are respectively fixed to the four same springs. After the adoption of the scheme, when the speed of the household electric bicycle is accelerated continuously, the rotating speed of the center shaft is accelerated continuously, the springs fixed to the cross-shaped rotating frame on the periphery of the center rotating shaft and the steel balls are rotated together; the speed is higher, the centrifugal force of the steel balls is higher, and the springs are elongated continuously so that the steel balls are in contact with the outer drum; as the outer drum is fixed, the steel balls move relative to the outer drum, and an effect of reducing the speed is achieved by friction.

Description

technical field [0001] The invention relates to a speed limiting device for a household electric vehicle, in particular to a household electric vehicle that uses a battery as a power source, works on the principle of mechanical friction, and can automatically adjust and limit the speed, thereby preventing the electric vehicle from overspeeding. speed limiting device. Background technique [0002] In modern society, electric vehicles, as a means of transportation in people's daily life, are more energy-efficient and environmentally friendly than cars and motorcycles, so they are very popular with everyone. Because electric vehicles are too fast and prone to collision accidents, from a safety point of view, it is very necessary to limit the speed of electric vehicles. For now, there are many ways to limit the speed of existing electric vehicles. After studying various domestic electric vehicle speed limiting devices, it was found that most of the household electric vehicle s...
