Problems solved by technology

In the hydraulic transmission system, the hydraulic pump is the "primary transducer element" that converts the mechanical energy input into the system into hydraulic energy, and the hydraulic motor is the "secondary transducer element" that converts hydraulic energy into mechanical energy and outputs the system. The hydraulic pump and The hydraulic motors use pressure oil as the carrier and transmit power through the pipelines connecting the two. Compared with mechanical transmission, the transmission efficiency is relatively low

Abstract

A transmission system capable of achieving three variable transmission processes comprises an input shaft, a sun gear shaft, an input gear, a linkage gear, an intermediate driving gear, a first clutch, a second clutch, a planetary mechanism, a hydraulic pump and a hydraulic motor. The input shaft and the sun gear shaft are arranged in parallel. The input gear is meshed with the linkage gear. The input end of the first clutch is in transmission connection with the input shaft. The driven end of the first clutch is fixedly connected with the input gear. The input end of the second clutch is in transmission connection with the sun gear shaft, and the driven end of the second clutch is fixedly connected with the linkage gear. A sun gear in the planetary mechanism is fixedly connected with thesun gear shaft. A tooth ring is fixedly connected with the intermediate driving gear. A planet carrier is fixedly connected with the linkage gear. A rotor of the hydraulic pump is fixedly connected with the input shaft. A rotor of the hydraulic motor is fixedly connected with the sun gear shaft. The hydraulic pump and the hydraulic motor are connected into an oil supply loop in series. The transmission system capable of achieving the three variable transmission processes enables the variable-speed transmission process to both have the features of mechanical transmission and hydraulic transmission, and therefore the transmission system capable of achieving the three variable-speed transmission processes can meet the variable transmission needs of different types of mechanical equipment.

Description

technical field [0001] The invention belongs to a power transmission system, and in particular relates to a variable-speed transmission system capable of realizing three transmission modes of pure hydraulic transmission, hydraulic-mechanical hybrid transmission and pure mechanical transmission. Background technique [0002] Variable speed transmission systems are widely used in various fields such as industry, agriculture, transportation and military equipment. In different types of industrial equipment, agricultural machinery, various types of vehicles, ships and military equipment and other mechanical systems, variable speed transmission systems are indispensable. key system modules. There are many ways to transmit power in the variable speed transmission system, but the transmission methods commonly used at present are still mainly mechanical transmission and hydraulic transmission. [0003] Mechanical transmission uses a system of various mechanical components to transm...
