[0002] There are two types of continuously variable transmissions currently in use. One is the hydraulic coupling type continuously variable transmission, which requires high machining accuracy, high manufacturing costs, and hydraulic oil is easy to leak. The other is the friction plate type continuously variable transmission. Slipping, unable to transmit large power, many faults, high maintenance cost

Abstract
The constant-coupling gear CVT relates to a motor vehicle CVT, especially a constant-coupling gear CVT, which is composed of a casing, a front differential device, a rear differential device, a tower gear mechanism, a power input shaft, Composed of power output shafts, the front differential device is composed of three planetary gears, three planetary gear shafts, sun gear, front differential device shaft bracket, transition gear, the tower gear mechanism is composed of three tower gears, three tower gear shafts The intermediate gear is composed of the front tower gear mechanism frame, and the rear differential device is composed of a central sun gear, three planetary gears, three planetary gear shafts and a fixed plate. , and change the transmission ratio, because it is a normally engaged gear structure, the transmission power is large, the wear is small, and the service life is long. It can be applied to various motor vehicles, especially large motor vehicles. The structure is simple and the manufacturing cost is low.
Description
Technical field [0001] The invention relates to a continuously variable transmission for motor vehicles, in particular to a continuously variable transmission with constant gears. Background technique [0002] There are two types of continuously variable transmissions currently in use. One is the hydraulic coupling type continuously variable transmission, which requires high machining accuracy, high manufacturing costs, and hydraulic oil is easy to leak. The other is the friction plate type continuously variable transmission. It slips, cannot transmit large power, has many faults, and has high maintenance costs. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a continuously variable transmission with constant gears, which not only has the torque transmission function of conventional transmissions, but also can automatically change the transmission ratio according to the magnitude of the resistance. ...
