Abstract
The invention relates to a vehicle variable transmission mechanism and a transmission method. The vehicle variable transmission mechanism comprises a power device and a speed reducer connected with a rotor of the power device. The rotor of the power device is connected with a first one-way bearing and a second one-way bearing in the opposite operating direction; and the speed reducer is arranged on the second one-way bearing and is connected with the rotor of the power device through the second one-way bearing. In the vehicle variable transmission mechanism, the power device drives vehicle wheels to operate through the first one-way bearing during normal driving so that the whole transmission mechanism is simple and is convenient to install and maintain, and the weight of the whole automobile is reduced. When the vehicle needs to climb, the second one-way bearing is connected with the speed reducer, and the speed reducer outputs low-speed and large-torque force after speed reduction so as to satisfy the requirement of climbing with load. In addition, as the operating directions of the first one-way bearing and the second one-way bearing are opposite, the speed reducer operates only when a large torque is output, the operating time of the reducer is shortened, the service life of the whole transmission mechanism is prolonged, and good stability is ensured.
