GEARSHIFT DRIVE IN MANUAL FIXED-RATIO TRANSMISSION

摘要

FIELD: transport. ^ SUBSTANCE: gearshift drive has gear selection and gear actuation mechanisms. The gear selection mechanism is a step motor mounted on the transmission casing. The gear actuation mechanism is a three-position pneumatic cylinder mounted on the gearshift shaft end with gearing between the rack and quadrant. The step motor is connected with the pneumatic cylinder so that the latter can reciprocate. ^ EFFECT: less time and money spent to modify the design. ^ 1 dwg
