Abstract
A synchronizing clutch made up of a quill shaft, a hub, a toothed sleeve for connecting the hub to the shaft and a clutch between the sleeve and the hub for synchronizing the speed of the hub with the speed of the sleeve prior to connecting the hub teeth to the shaft teeth. Drive pins are provided on the shaft for preventing the teeth from interfering at synchronization and an improved adjusting means and a retaining ring provide a space for the clutch discs so that the axial position of the clutch discs relative to the drive pins prior to synchronism is always precisely known.
Claims19
A synchronizing clutch comprising,
- a first member including a first coupling teeth,
- a second member including a second coupling teeth adapted to be moved into engagement with said first coupling teeth,
- synchronizing means on said clutch for synchronizing said coupling teeth,
- said synchronizing means comprising a cylindrical disc carrier on said first member having an adjusting ring fixed to one end thereof and a retaining ring fixed to the other end defining a space,
- first discs supported on said disc carrier in said space,
- a pressure ring on said disc carrier adjacent said retaining ring,
- second discs connected to said second member and supported between said first discs,
- one of said second discs being relatively thick and having kidney-shaped holes therein and disposed in engagement said with said pressure ring,
- and drive pins extending through said pressure ring and adapted to engage said holes in said relatively thick disc when said first member and said second member are synchronized with each other,
- said pressure ring constituting a positive locating means for said relatively thick disc relative to said drive pins whereby the position of said pins relative to said relatively thick disc is determined.
A synchronizing clutch comprising,
- a drive shaft,
- a load end hub having a hub thereon,
- first clutch plate means, and
- synchronizing means,
- said synchronizing means being adapted to connect said drive shaft to said driven member,
- second clutch plates including a relatively thick clutch plate,
- a pressure ring engaging said thick clutch plate and positioning said clutch plate relative to said drive pins, and means fixing said pressure ring to said disc carrier,
- said synchronizing means comprising drive pins on said pressure ring adapted to loosely engage holes in said relatively thick clutch plate.
- balking means,
- said balking means being adapted to prevent said drive pins from engaging said holes in said thick plate until said shaft has reached synchronized speed with said load end hub.
