Abstract

The invention discloses a middle drive system for electric bicycles. The middle drive system comprises a motor, a transmission reversing mechanism and a middle shaft. The middle shaft is rotatably disposed in a middle shaft case, and two ends of the middle shaft are in drive connection with pedals. The middle shaft case is mounted on a bottom bracket of an electric bicycle. A torque sensor is disposed on the middle shaft and electrically connected with a controller. The controller is electrically connected with the motor. The transmission reversing mechanism comprises a first clutch and a second clutch, wherein the first clutch is composed of an inner ring and a middle ring and the second clutch is composed of an outer ring and the middle ring. The first clutch and the second clutch lock in opposite directions. The inner ring is fixed on the middle shaft, and a driving sprocket is fixed on the middle ring and is in drive connection with a driven sprocket of a rear axle of the electric bicycle, and the outer ring is in drive connection with the motor. The middle drive system is high in drive efficiency, simple to install and convenient to maintain, allows for switching between manpower and motor drive by adding the controller and the torque sensor for the adjustment of motor output, and enables riding laborsaving and convenient.

Description

technical field [0001] The invention relates to a mid-mounted drive system for an electric bicycle. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source, and is equipped with motors, controllers, batteries, steering handles, brake handles and other operating components and display instrument systems on the basis of ordinary bicycles. Most of the existing electric bicycle drive systems place the motor at the axis of the rear wheel, and the motor directly drives the rear wheel to rotate. This method has complex structure, difficult installation, and inconvenient maintenance. The power switching is not smart enough, which causes the problem of strenuous riding. Contents of the invention [0003] The purpose of the present invention is to address the above problems and provide a mid-mounted drive system for electric bicycles to solve the problems of complex structure, difficult installatio...
