Abstract: An adjustable toe board, an adjustable toe board assembly, kit and sawmill comprising the adjustable toe board are provided. The toe board comprises a baseplate having a first end, an opposed second end, and a rod extending away from the baseplate. The toe board includes a support bar pivotably coupled to the baseplate proximate the first end, spaced apart from the rod, and extending towards the second end, the support bar being configured to support a log. The toe board also includes a ratcheting arm pivotably coupled to the support bar, the ratcheting arm having a plurality of spaced-apart teeth defining notches adapted and positioned to selectively engage with the rod, wherein selective engagement of the teeth with the rod enables pivotal adjustment and releasable locking of the support bar relative to the baseplate during operation.

Abstract: A shifting device for a positively engaging clutch having complementary first and second positively engaging coupling elements includes a housing and an actuator rod which is axially movable within the housing by means of an associated rod actuating mechanism. A clutch shift fork for engagement with the first coupling element is mounted on the actuator rod for axial movement of the first coupling element into and out of engagement with the second coupling element in response to axial movement of the actuator rod. The clutch shift fork is mounted on the actuator rod by a threaded connector such that the clutch shift fork is axially movable on the actuator rod. Thus conveniently the axial position of the clutch fork on the shaft may be altered by rotating the shaft relative to the clutch fork for accurate positioning of the clutch fork relative to the coupling element with which it engages.

Abstract: In one aspect a propulsion system comprises an engine and a drive assembly coupled to the engine, comprising a first driveshaft rotatable in a first direction about a first axis, a first fan coupled to the first driveshaft to rotate in the first direction, and a clutch assembly to selectively disengage the first fan from the first driveshaft. Other aspects may be described.

Abstract: A shift rail rod seal for a transmission shift apparatus. The rod seal includes a case that is over-molded with a seal body that includes a seal lip for engaging a shift rail and a chamfered lip that engages the seal bore chamfered bore entrance when the rod seal is correctly assembled into the seal housing bore. A transmission shift apparatus that is adapted to receive the shift rod seal includes a manifold housing and a clutch housing that together form a sealed cavity. A shift rail and piston are received in the sealed cavity that is pressurized to actuate the shift apparatus.

Abstract: A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The actuation device further includes a first set of wiper seals and a second set of wiper seals disposed in a first and a second annular channel in each of the annular pistons. Advantageously, contamination of the piston chambers is reduced or eliminated through the wiping or cleansing action of the first and second set of wiper seals against walls of the annular slots formed in the housing of the actuation device.

Abstract: A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons include a first end that is in contact with annular bearing assemblies. The annular bearing assemblies are in contact with actuation levers that are in contact with the first set of frictional elements. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The piston chambers are filled with hydraulic fluid. When the hydraulic fluid is pressurized the pistons slide out of the annular slots and apply a force on the actuation levers which in turn apply an axial compression force on the frictional elements.

Abstract: A dual clutch actuation assembly includes a housing, an annular central piston, a plurality of satellite pistons, and an annular apply member. The housing includes an inner cylindrical wall, an outer cylindrical wall, and a plurality of satellite cylindrical walls. The inner and outer walls define an inner piston annulus and the satellite walls define a plurality of satellite piston bores. Each of the satellite walls is disposed at least partially radially outward of the outer wall. The central piston is disposed in the inner piston annulus and is in sliding engagement with the inner and outer walls of the housing. The satellite pistons are disposed in the satellite piston bores and are in sliding engagement with the satellite walls of the housing. The apply member is axially engaged with each of the satellite pistons and includes an annular plate portion disposed radially outward of the outer cylindrical wall of the housing.

Abstract: A dual clutch, which has a first friction clutch pulled by a first lever actuator and a second friction clutch pushed by a second lever actuator. The lever actuators each have a lever that is spring-loaded on one side and lever tips which are moved by a bearing block. The bearing block can be moved radially with along a profile of the lever to set a variable contact point of the lever between a rigid base plate and the lever to act on actuating bearings of the friction clutches. The bearing block is actuated by force application in one of the radial directions of motion by a drive controlled by a control unit in an automated manner. The drive of both lever actuators is formed by a pneumatic controller. In each drive a piston is movable in a housing and is connected to the bearing block by a piston rod.

Abstract: In transmissions having input clutches, a lever arm configured as a second class lever is pivoted at one end, applies force to a clutch bearing near its middle and is acted upon by a linear actuator at its opposite end. The present invention relates to mechanisms for adjusting the location of the pivot to compensate for clutch wear. The fixed pivot is replaced by a linear one way clutch mechanism. As the clutch facing wears and the clutch is activated, an extension of the actuating lever arm abuts a stationary stop beyond the one way clutch pivot which translates the pivot point provided by the one way clutch mechanism toward the clutch to reduce pre-travel and compensate for clutch facing wear. Hydraulic and spring biasing of the pivot point are also disclosed.
