Problems solved by technology

[0004] 1) The metal belt continuously variable transmission system or its deformation requires a complex hydraulic system to realize the clamping force control of the metal belt and the speed ratio control of the transmission system, and there is a complex coupling effect between the clamping force and the speed ratio control
In practice, the structure of the hydraulic system is complex and the efficiency is low, so the efficiency of the entire transmission system is also low
[0005] 2) Due to the limitations of its own mechanical structure, the metal belt type continuously variable transmission system has a small range of speed ratio (the ratio of the maximum speed ratio to the minimum speed ratio of the system) (about 5~6). The mechanism increases the range of the transmission ratio, bu

Abstract

The invention relates to a electric horn machinery planetary mechanism step-less variable speed transmission system, it belongs to vehicle transmission technology field. The system is make up of mutual meshing gear (Z1), idle gear (Z2) and gear (Z3), planetary mechanism, input axis (1), axle sleeve (2), input axis (3), output axis (4), mutual meshing gear (Z4) and (Z5), motor (6), inverter and battery. The biggest advantage of invention is using a lower power speed control motor to realize the speed ratio continuous step-less change of whole system. To compare with mainstream step-less variable speed transmission system, the speed ratio change range of invention is larger, transmission efficiency is higher and has lower cost, simple and compact structure, stable transmission, high ability of transfer power and torque and easy application of advanced control strategy. The invention has widely prospect on common automobile especially the electric vehicle transmission system.

Description

Technical field: [0001] The invention relates to a continuously variable transmission system of an electric mechanical planetary mechanism, which belongs to the technical field of vehicle transmission. Background technique: [0002] The function of the vehicle transmission system is to transmit the power of the power source to the drive wheels, and to change the traction force and vehicle speed according to the requirements of the vehicle. Continuously variable transmission is the development trend of vehicle transmission, and is considered to be the most ideal transmission mode. The continuously variable transmission system can continuously and steplessly change the speed ratio (the ratio of input speed to output speed) according to the driving conditions of the vehicle and the working state of the engine. ), so that the engine can always work in the most efficient area, realize the best match between the external conditions and the vehicle, and enable the vehicle to obtain...
