A rotational coupling includes a hub assembly configured for rotation about a rotational axis. The hub assembly includes a hub disposed about the axis and configured to receive a shaft and a disc extending radially outwardly from the hub. An armature and electromagnet are disposed on opposite axial sides of the disc. The electromagnet is fixed against rotation. A bearing is disposed between the hub and the electromagnet. The hub assembly and electromagnet are separated by an air gap on an outboard side of the bearing. A debris shield is axially aligned with, and extends across the radial length of, the air gap and, in some embodiments, is at least partially disposed within the air gap. The shield has a fixed end coupled to one of the hub assembly and electromagnet during assembly and a free end configured to engage the other through a spring force and/or electromagnetic attraction.

Rotational coupling device with bearing shield

A clutch assembly includes a clutch disc configured to engage a prime mover, a pressure plate having a clutch biasing element, and a clutch engagement member structured to couple to a clutch actuation element at an engagement position. The clutch adjustment member maintains a consistent engagement position as a face of the clutch disc experiences wear.

Clutch assembly having high repeatability and servicability

An adjustment mechanism for a clutch is positioned between the diaphragm spring and the pressure plate, the adjustment mechanism including: a first cam ring rotatably fixed with respect to the pressure plate, a second cam ring rotatable relative to the first cam ring and both cam rings having a plurality of cam surfaces configured such that rotation of the second cam ring relative to the first cam ring varies a height of the adjustment mechanism, and a torsion spring including a longitudinal axis. The torsion spring is disposed in the annular groove. The torsion spring includes a helical round cylindrical body that extends to a first end connected to the first cam ring and the torsion spring has a second end connected to the pressure plate. The torsion spring applies a biasing force to the second cam ring promoting rotation of the second cam ring relative to the first cam ring. The pressure plate includes a locking slot formed therein partially through the pressure plate and through the opposing surface. The locking slot is formed at an angle relative to the opposing surface and the second end of the torsion spring includes a locking hook formed thereon. The locking hook extends perpendicular to the longitudinal axis of the torsion spring. The locking hook is disposed in the locking slot fixing the locking hook relative to the pressure plate.

Transmission clutch including locking torsion spring

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

High efficiency, high output transmission

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

A dry friction clutch for connecting a transmission with a flywheel of an engine is provided. The clutch includes a bracket having a main body axially spaced from an engine flywheel. The bracket is torsionally connected to the flywheel. The bracket has a generally U-shaped cross section with a main body connected with generally axially extending side walls. An axially movable pressure plate is torsionally connected with the bracket. The pressure plate is axially movable within the bracket. A friction disc is provided having a connection with an input shaft of a transmission. The friction disc is axially positioned between the flywheel and the pressure plate. A release assembly is provided including a spring for urging the pressure plate toward the flywheel. The bracket side walls have inward positioned barbs to axially limit travel of the pressure plate.

Bracket barb pressure plate stop

A dry friction clutch is provided having an innovative baffle design wherein the baffle has a tab that sets the limit for maximum adjustment of an adjustment mechanism of the dry clutch.

Cam hard stop for end of life

The present invention provides an arrangement of a vehicle with a clutch release bearing and a lubrication path through a bell housing of a transmission.
