Abstract: A vehicle transmission system includes a transmission component that has an engaged condition where torque can be transferred from a vehicle engine to a drive component, and a non-engaged condition where torque is prohibited from being transferred to the drive component. A controller generates control signals to control whether the transmission component is in the engaged or non-engaged condition. The controller also identifies when a vehicle start maneuver is a coast start based on vehicle conditions existing just prior to or during the vehicle start maneuver. When a coast start is identified, the controller generates a control signal to either disengage the transmission component or to maintain the transmission component in the non-engaged condition until engine speed generally matches transmission component speed. The controller can directly control engagement by automatically actuating a movable transmission member or can indirectly control engagement by controlling engine speed.

Abstract: The invention relates to a device for measuring the temperature of an oil in a housing (4) of a transmission (2) with a temperature sensor (20) which can come into contact with the oil. The temperature sensor (20) is arranged outside the oil sump (16) in the transmission housing (4) and is preferably integrated directly in the transmission controller (18).

Abstract: In a hydrodynamic brake (1), in order to reduce the ventilation losses, adjustable baffles (2, 20) are situated between a rotor (3) and a stator (4). During idling, when oil has been evacuated from the brake (1), one or more baffles (2, 20) of angular cross section in the outer area of the toroidal chambers (31, 41) separate the chambers via a radially inward projecting annular leg (21), a leg cylindrically situated in an axial direction abutting against the inner wall (52) of a chamber (5). During operation of the brake, that is, when the hydrodynamic brake (1) is filled with oil, the radially inward projecting leg (21) is located with its front edge (29) behind the toroidal chambers (31, 41). When only one baffle (20) covering the entire periphery of the outer area of the toroidal chambers (31, 41) is installed, slits (23, 28) are disposed in the radially inward projecting annular leg (21) to obtain the adequate elasticity.

Abstract: A process and device for cleaning lubricating oil in a gearbox with pressurized oil lubrication of bearings and gears is described wherein a lubricating oil pump delivers lubricating oil from a container, preferably the oil pan of the gearbox. In a shaft of the gearbox, preferably the input shaft, the lubricant channel is expanded into a rotation chamber. Flow velocity is thereby greatly reduced and the rotation of the outer surface of this chamber is imparted to the lubricating oil. As a result of this, the dirt particles are centrifuged onto the outer surface, where they form a firmly adhering film. The cleaned lubricating oil is drawn off in the center of the rotation chamber and conveyed in known manner via a bore provided in the main shaft to oil consumer parts, e.g. the bearings.

Abstract: An oil lubrication system for a bearing positioned between two rotatable shafts, especially a pilot bearing (1) for a main shaft (3) in a transmission. The lube oil is fed predominantly radially inwardly on one side (11) of the pilot bearing (1) and is radially drained outwardly on the other side (12) via an annular drainage passage (8) located between the two shafts. An elastic rubber seal (4) is situated in the drainage passage (8) which, during operation, is opened by the centrifugal force or by the pressure of the lube oil pumped through the system and closes the drain passage (8) during downtime of the transmission. The elastic rubber seal (4) can be fastened to the input shaft (2) via a body (44) especially when the sealing lip (41) is to be opened by the centrifugal force. In addition, fastening to the main shaft (3) is also possible when the sealing lip is to be predominantly opened by the oil lube pressure pumped to the pilot bearing (1).

Abstract: Gear-shift device for variable transmissions with shift dogs (6) in or on the gearing, which can be actuated from a manual shift lever, engage into shift rails (3) and displace these within limits, and with shift rocker arms (1) engaging in the recesses (31) of the shift rail (3) and actuating clutch sleeves (51) of the shifting couplings (5) over slide cranks (11). Between a shift rocker arm (1) and shift rail (3) a reversing lever (2) is provided, which reverses the actuation direction of the shifting coupling (5) in such a manner that the shift rail (3) and the clutch sleeve (51) are moved in the same direction although the support of the shift rocker arm (1) is arranged between the slide cranks (11) and the shift rails (3).
