Abstract

1435517 Change-speed control BRITISH LEYLAND TRUCK & BUS DIVISION Ltd 31 Aug 1973 [23 Sept 1972] 44126/72 Heading F2D Means for synchronizing at least one gear train 22, 21, between an engine-driven countershaft 14 and output shaft 18 of a motor-vehicle change-speed gear, comprises an electric motorgenerator 30 connected to the countershaft through a wheel pair 32, 31, so that, during a shift, with the main clutch disengaged, the motor generator 30 can be caused to accelerate or decelerate the countershaft for synchronous engagement of a dog clutch 27 between the wheel 22 and the countershaft. The motor generator 30 receives an error signal proportional to the speed difference produced by an electronic signal generator not described, which engages the dog clutch 27 on synchronism.
