Drive device with coupler

Abstract

The invention provides a drive device with a coupler. The drive device comprises a moving component, a coupler assembly, a low-speed motor, a transmission system, a first current controller and a battery assembly; the battery assembly is connected to the low-speed motor through the first current controller; the coupler assembly includes the low-speed coupler and a low-speed shaft; the low-speed motor drives the low-speed shaft through the transmission system; the low-speed coupler includes a coupler housing fixedly connected to the moving component, a transmission mechanism and a rhombic rotor; the coupler housing is connected to the low-speed shaft through a shaft, and the rotor is fixedly connected to the low speed-shaft. When the transmission mechanism tightly abuts against the rotor, the transmission mechanism tightly abuts against the inner wall of a cavity. When the transmission mechanism is separated from the rotor, the transmission mechanism is separated from the inner wall ofthe cavity.

Description

technical field [0001] The invention relates to the technical field of transmission components, in particular to a driving device with a coupling. Background technique [0002] Most of the present automobiles adopt fuel vehicles. As we all know, another major factor of air pollution is automobile exhaust. Automobile exhaust contains carbon monoxide, nitrogen oxide and other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body. Lead is in the form of particles in the exhaust gas and diffuses with the wind. Rural residents generally inhale about one microgram of lead per day from the air; urban residents, especially those on both sides of the street, will greatly exceed rural residents. After tin enters the human body, it is mainly distributed in the liver, kidney, spleen, gallbladder, and brain, with the highest concentration in the liver and kidney. After a few weeks, lead is transferred from the ...

Problems solved by technology

This invention uses dual motors to drive the rear wheels, and utilizes the ability of the low-speed motors to drive normally, and only increases the high-speed motor to drive the rear wheels through gears to change the speed ratio when starting or climbing a slope. This driving device cannot be used in large-scale electric vehicles. tools, and can only be applied to one wheel hub. In electric vehicles in current technology, the technology of installing three motors in each of the four hubs has not been solved

The driving devices of existing electric vehicles, electric buses or electric passenger cars and other electric vehicles are all driven by a single motor, which has the problems of small starting torque and low motor efficiency when starting, and there is insufficient power when climbing, and climbing The low efficiency of the motor during slope will lead to high current operation, causing damage to the battery and controller, shortening the battery life and other problems
