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.

Systems and apparatuses for articulating float arms of a harvester header between a flexible configuration and a rigid configuration are disclosed. The systems and apparatuses include a locking tube that experiences no torque or approximately no torque when the float arms are in the rigid configuration. Further, the systems and apparatuses also avoid adjustments to ensure that float arms are fully retracted, such as into abutting contact with another portion of a header.

Friction clutch pressure plate device 11 which is provided between spring device 12 and clutch disc unit 4 of friction clutch 1 comprises primary pressure plate 19, secondary pressure plate 22 which is capable of approaching and receding from primary pressure plate 19, and a plurality of weight plates 23 which are slidably arranged between mutually opposed side faces 19a, 22a of primary pressure plate 19 and secondary pressure plate 22. Primary pressure plate 19 comprises first outer circumferential wall 25 having inclined inner wall face 24, secondary pressure plate 22 comprises second outer circumferential wall 28 having perpendicular inner wall face 27, and weight plate 23 comprises tip portion engaging surface that engages with perpendicular inner wall face 27 and a tip portion inclined surface 32 that engages with inclined inner wall face 24.

A self-adjusting clutch actuator includes a transmission element displaceable in a displacement direction; and a compensation mechanism having a piston displaceable in the displacement direction of the transmission element. The compensation mechanism allows a first relative displacement (X) of the transmission element relative to the piston in the displacement direction when there is no actuating force in the clutch actuator, and blocks the first relative displacement (X) when an actuating force is introduced into the clutch actuator by bringing a frictional element (4) into contact with a counter-element. The frictional element (4) is designed for a second relative displacement (Y) relative to the counter-element when the first relative displacement (X) is not blocked by the compensation mechanism (22). A translatory mechanism provided between the transmission element (1) and the piston (2) is designed to cause the second relative movement (Y), by the first relative displacement (X) relative to the counter-element.

The present invention pertains to a drive connection for coupling an engine to a gearbox of a machine and which provides a fluid-tight sealing. Accordingly, a drive connection for coupling an engine to a gearbox of a machine is suggested, which comprises a housing having an inner cavity that extends from a first open end of the housing to a second open end of the housing and which is configured for accommodating and enclosing a clutch. The housing defines a first coupling interface at the first open end for coupling the drive connection to an engine and a second coupling interface at the second open end for coupling the drive connection to a gearbox, Furthermore, each coupling interface comprises a sealing member, wherein the housing and sealing members are configured to fluidically seal the inner cavity, when the drive connection is in a coupled state.

A friction clutch mechanism includes a diaphragm spring, a pressure plate having a peripheral fulcrum acting against a first face of the diaphragm spring, and a pair of axially opposed intermediate fulcrums supported by a clutch cover and acting on the opposite faces of the diaphragm spring along a radially intermediate portion thereof. The friction clutch mechanism has an additional elastic element, operatively associated with a first intermediate fulcrum of the pair of axially opposed intermediate fulcrums, and axially and elastically compressible in response to a deflection of the diaphragm spring towards an open friction condition. The additional elastic element has a radially innermost annular portion resting on one or more bearing surfaces supported by the clutch cover, and a radially outermost annular portion that cantilevers and has a protrusion circumferentially extended and axially projecting towards the first face of the diaphragm spring to serve as the first intermediate fulcrum.

An improved pressure plate and clutch assembly allowing for use of a Bellevue (or diaphragm) spring and/or a series of coil springs in the clutch assembly. A Bellevue spring alone can be utilized with the pressure plate; a series of coil springs alone can be utilized with the pressure plate; or alternatively both a Bellevue spring and a series of coil springs can be utilized. The pressure plate has features that allow for either or both of the spring types to be utilized to bias the pressure plate. This allows for the selection of either spring type or both spring types. The pressure plate further preferably has features to allow for a spring or similar biasing mechanism to exert an opposing force to the Bellevue and/or series of coil springs.

A clutch structure that includes a motor to directly drive a rotary disc of an actuation unit, and the actuation unit further directly act on a push unit, so as to achieve reduction of size. Further, the push unit has a spring holder that drives a push bracket to press against a clutching unit, and the push bracket and the clutching unit are rotatably in synchronization with each other and a group of balls is arranged between the push bracket and the spring holder, such that smooth rotation can be maintained even during the process of pressing to thereby effectively reduce pause and setback incurring in coupling and connection and also to efficiently establish a transmission clutching force to have the operability not affected by the delay.
