Complementary wheels balancing stepless speed changer

Abstract

The invention belongs to the technical field of mechanical transmission, in particular improved stepless transmission with balanced male and female wheels of mechanical transmission, which comprises an active input unit and a primary slave output unit, wherein the active input unit and the primary slave output unit are connected by driving belts, the active input unit is provided with a pair of female wheel and male wheel which are capable of interlacing, the female wheel and the male wheel are equipped with interlacing conical faces which are complementary, the female wheel is fixed on an active output shaft, the male wheel sleeves the active output shaft and can slide left and right, the composition of the primary slave output unit is the same with the active input unit, additionally a regulating mechanism is included, and the regulating mechanism simultaneously drives the main input unit and the male wheel in the primary slave output unit to slide left and right on respective shaft. Because of the specific composition, male and female interlacing complementary structure is formed on the surfaces of the female wheel and the male wheel, the driving belts are attached to the intercrossing surface of the female wheel and the male wheel, have a big stress face and are pushed against by a sliding block inclined surface, the driving belts is radially formed into an S shape for bearing force, thereby increasing the friction, enabling the driving belts to be not easy to slip, and meeting the specific requirement of conventional CTV structure to driving belts.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, in particular to the improvement of a mechanical transmission. Background technique [0002] The automobile was born thanks to the internal combustion engine. However, the power characteristics of the internal combustion engine are low power, low torque, and high fuel consumption at low speeds. However, the best working condition of high power, high torque and low fuel consumption can only be realized in the middle and high speed range. The dynamic characteristics of the internal combustion engine are not consistent with the requirements of the automobile on the dynamic characteristics, and even deviate from them. In order to make the car start smoothly and run normally, it is necessary to reduce the speed, so the transmission appeared. The change of the driving speed of the car is continuous, which requires the speed ratio of the gearbox of the car to be continuous, so the Con...
