Problems solved by technology

Because the generator has a certain speed requirement when generating electricity, the energy recovery electric vehicles currently on the market use brushless toothed motors, but in order not to affect the sliding of electric vehicles, the planetary gears inside the brushless toothed motors A one-way clutch is installed on the transmission, which means that the motor can only drive the hub to rotate, but the hub cannot drive the motor to rotate

Embodiment Construction

[0013] Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the application. The terminology used herein in the description of the application is only for the purpose of describing specific embodiments, and is not intended to limit the application. The motor mentioned in this article is a drive motor, a generator motor, and a motor that can both generate electricity and drive. Electric vehicles mentioned in this article include electric bicycles, electric motorcycles and electric cars.

[0014] At least one brake caliper (2) is arranged and assembled on the casing (1) of the transmission, so that the brake caliper (2) brakes the planetary gear carrier (9) directly or through a brake disc (5). When the brake caliper (2) is used to brake the planetary gear carrier (9) through the brake disc (5), the brake disc (5) and the planetary gear carrier (9) are fixedly assembl...

Abstract

The invention discloses a variator and an electric vehicle equipped with the variator. A housing (1) of the variator is provided with at least one brake caliper (2), and the brake caliper (2) brakes aplanetary gear carrier (9) directly or through a brake disc (5). The brake caliper (2) is controlled by a pedal or a handle through a brake cable or a hydraulic oil pipe, and when the electric vehicle needs to be braked in an auxiliary mode through motor power generation during downhill running, the brake caliper (2) is controlled by the pedal or the handle to brake the planetary gear carrier (9)so that the planetary gear carrier (9) cannot rotate, according to the characteristics of a planetary gear transmission, at the moment, an outer gear ring (8) transmits energy to a sun gear (6) through a planet gear (7), the sun gear (6) drives a motor rotor to rotate, and a motor is driven by a wheel hub to rotate at a high speed and generate power.

Description

technical field [0001] The invention relates to a speed change machine including a speed change motor, in particular to a planetary gear speed changer and an electric vehicle equipped with the planetary gear speed changer. Background technique [0002] At present, energy recovery electric vehicles are gradually being used. Energy recovery means that when the electric vehicle goes downhill, the drive motor instantly turns into a generator to generate electricity, and the resistance of the electricity generated is used to assist braking, and the generated electricity is used to extend the cruising range. Because the generator has a certain speed requirement when generating electricity, the energy recovery electric vehicles currently on the market use brushless toothed motors, but in order not to affect the sliding of electric vehicles, the planetary gears inside the brushless toothed motors A one-way clutch is installed on the transmission, which means that the motor can only ...
