Abstract

The invention provides a variable speed control system of a four-gear transmission. A controller is connected with an eight-gear transmission. The four-gear transmission comprises an input shaft, an output shaft, an intermediate shaft, a first switching type clutch, a second switching type clutch, a shell, an oil way structure and an oil way control system. The controller comprises multiple analogoutput units, and the multiple analog output units are connected with a first adjusting and controlling unit and a second adjusting and controlling unit. The controller is used for acquiring gear position information and controlling the analog output units to output different kinds of analog control information to the adjusting and controlling unit and the second adjusting and controlling unit according to the control corresponding relation of the pre-stored gear information and the analog output units. By means of the variable speed control system, the aim of automatic and rapid gear shifting is achieved through the controller.

Description

technical field [0001] The invention relates to the field of transmission control systems, in particular to a four-speed transmission control system. Background technique [0002] The four-speed transmission can realize the change of four gears, and through different gear changes, different torques input from the front and rear can be changed. Through the switching of different clutches of the transmission, the switching of different gears of the transmission can be realized. Existing manual gear shifting can be realized by manually opening and closing proportional valves of different clutches. In order to realize fast and automatic transmission gear switching, a transmission gear control system is required. Contents of the invention [0003] For this reason, it is necessary to provide a speed change control system for a four-speed transmission to solve the problem that the existing transmission needs to be automatically and quickly shifted. [0004] In order to achieve...
