Adjustable hydraulic slave cylinder for clutch incorporating a spring biased pressure plate
View Patent ↗A novel adjustable slave cylinder is disclosed. The improved slave cylinder is particularly well suited for use with a clutch incorporating an expanding friction disk. The adjustable slave cylinder provides a means for adjusting a clutch pressure plate's position via an adjustment mechanism external to the inside of an engine.
1. A hydraulic clutch disengagement system comprising a master cylinder assembly and a slave cylinder assembly comprising a slave cylinder piston mechanically connected to a throwout rod, a threaded adjuster, and a slave cylinder body, said slave cylinder body including a hole to receive said threaded adjuster; wherein said threaded adjuster is operational external to an engine case to adjust the position of said slave cylinder piston and said throwout rod and said master cylinder assembly is operational such that when activated, said master cylinder assembly will displace said slave cylinder piston in a direction away from said threaded adjuster creating a disengaged gap between said slave cylinder piston and said threaded adjuster and when said master cylinder assembly is not activated, said slave cylinder piston is in contact with said threaded adjuster.
2. The hydraulic clutch disengagement system of claim 1 wherein said slave cylinder piston is operational to displace a pressure plate away from a clutch pack.
3. The hydraulic clutch disengagement system of claim 1 wherein said threaded adjuster is operational to create an installed gap between a pressure plate and an expandable friction disk.
4. The hydraulic clutch disengagement system of claim 3 wherein said threaded adjuster is operational to remove an installed gap between a pressure plate and an expandable friction disk.
5. The hydraulic clutch disengagement system of claim 1 further comprising an adjuster seal; said adjuster seal operational to prevent fluid from escaping from said slave cylinder assembly.
6. The hydraulic clutch disengagement system of claim 1 wherein said threaded adjuster is operational to create an installed gap between a pressure plate and a centrifugal mechanism.
