Abstract

The invention relates to a variable speed control system for an eight-gear transmission. The variable speed control system comprises a controller. The controller is connected to the eight-gear transmission. The eight-gear transmission comprises an input shaft, an output shaft, a gear pair unit, a first intermediate shaft gear bank, a second intermediate shaft gear bank, a center shaft, an oilway structure and an oilway control system. The controller comprises a plurality of analog quantity output units which are separately connected to a first regulation unit, a second regulation unit and a third regulation unit. The controller is used for acquiring gear information and controlling the analog quantity output units to output different analog quantity control information to the first regulation unit, the second regulation unit and the third regulation unit according to a control corresponding relationship between the prestored gear information and the analog quantity output units. The variable speed control system achieves an automatic quick gear shifting purpose by the controller.

Description

technical field [0001] The invention relates to the field of transmission control systems, in particular to an eight-speed transmission control system. Background technique [0002] The eight-speed transmission can realize the change of eight 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 an eight-speed transmission to solve the problem that the existing transmission needs to be automatically and quickly shifted. [0004] In order to a...
