DRIVE SYSTEM WITH SERVO MECHANISM FOR AUTOMOTIVE MULTISPEED GEARBOX Russian patent published in 2014 - IPC F15B15/14 F16H61/30 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry. This system comprises cable connection (10), servo cylinder (30), piston (32) arranged to slide inside servo cylinder to divide its inner space into inner and outer chambers (36, 38), piston rod (34) coupled with piston and extending outside thereof, and adjusting valve (60) communicating with working medium source. Note here that one end of the cable can be connected with gearbox control lever (2). Its opposite end can be connected with adjusting valve (60) for fluid selective feed into servo cylinder. Note here that piston rod (34) is furnished with first fastener (40) to be arranged at carrier structure fixed component (4). Servo cylinder is provided with second fastener (50) to couple servo cylinder with gearbox control link (6). Note also that said cable extends through said central trough bore (35) in lengthwise direction and piston assembly into servo cylinder (36) wherein cable is connected with drive lever (62). The latter can transfer lengthwise displacement of cable (14) to control vale for its actuation. Note that said cable is fitted in said through hole to slide therein. Through hole seal accommodates push-pull cable to prevent working fluid leaks at pressure from servo cylinder.

EFFECT: decreased overall dimensions.
