Title:
MULTISTAGE TRANSMISSION
Document Type and Number:
Japanese Patent JP3422430
Kind Code:
B2
Abstract:
PURPOSE: To minimize the change in the number of stages of the vehicle speed when transmission mechanisms 2, 3 are operated for the speed change in a multistage transmission where the vehicle speed can be changed to the prescribed number of stages by the combination of a plurality of transmission mechanisms 1, 2, 3.
CONSTITUTION: An input means 6 to change the speed of a power shift transmission mechanism 1 and detecting means 65H, 65L, 73 to detect the shift condition of other transmission mechanisms 2, 3 than the power shift transmission mechanism 1 are provided, and the control signal to be outputted to a hydraulic actuator 9 according to the input signal when the input means 6 is operated is set. A transmission control means to set the control signal to be outputted to the hydraulic actuator 9 is provided so that the change in the number of stages of the vehicle speed may be minimum according to the input signal from the detecting means 65H, ' 65L, 73 before and after the operation when other transmission mechanisms 2, 3 than the power shift transmission mechanism 1 are operated.
