摘要:
The invention relates to a multi-disk clutch or multi-disk brake (1, 2), comprising an inner disk carrier (4) carrying internal disks (3) and an outer disk carrier (6) carrying external disks (5), friction linings (7, 7′) on the internal and external disks (3, 5), a first end disk (9), on which a closing force for the multi-disk clutch or multi-disk brake can be applied by a piston (10) of a piston-cylinder arrangement which can be actuated by a pressure medium, and a second end disk (8), which forms an axial abutment for the clutch pack (14) formed by the disks (3, 5, 8, 9), wherein the multi-disk clutch or multi-disk brake (1, 2) and/or the components encompassing the clutch or the brake are configured such that the internal and external disks (3, 5) can be wetted with a cooling oil (13). So as to improve heat dissipation during operation, it is provided that the multi-disk clutch or multi-disk brake (1, 2) is configured such that the cooling oil (13) can be directed axially through the clutch pack (14).
摘要:
A method for operating power train side components of a motor vehicle. Using a control device of a motor, at least one motor parameter is issued and delivered via a databus to at least one control device of one other power drive side component working independently of the motor control device in order to operate all or each one of the power drive side components dependent in a first inventive aspect, a behavior of the respective other power drive side components that adjusts itself according to the motor torque actually made available by the motor is evaluated. In second inventive aspect, the motor torque issued by the motor control device is compared with a torque stored according to motor operation parameters in the control device working independently of the motor control device.

摘要:
A transmission oil pump for an automatic transmission of a motor vehicle. The speed of the oil pump can be shifted by a transmission (2), that is arranged between the drive motor of the motor vehicle and the transmission oil pump, to a fast-running mode or a slow-running mode so that the oil pump can be operated at two different speed levels.
摘要:
A method for operating an automatic transmission of a motor vehicle, in particular a variable-speed transmission. The automatic transmission includes at least five shift elements and to transfer torque or force transfer in a forward gear and a reverse gear at least three shift of the at least five elements are engaged. When shifting the automatic transmission from a neutral position to a forward or a reverse gear, at least one of the three shift elements of the automatic transmission that are engaged in the respective forward or reverse gear, is engaged in a controlled manner.
摘要:
A method for operating an automatic transmission of a motor vehicle, in particular a variable-speed automatic transmission. The automatic transmission has five shift elements and for transferring torque or force in a forward gear and in a reverse gear at least three of the five shift elements are engaged. In a neutral position of the automatic transmission, to prevent torque or force flow at least one of the shift elements that are engaged in the respective forward or reverse gear is fully disengaged.

A drive control device of an automatic transmission of a vehicle. The transmission having a main oil pump driven by an internal combustion engine, an electrically driven auxiliary oil pump and a hydraulic control device; a device for determining the required volumetric flow rate needed to determine the oil/hydraulic target volumetric flow rate during current operating conditions, based on the transmission oil temperature; a device for determining the volumetric flow rate to determine the actual volumetric flow rate that can be delivered during the current operating conditions by the main and/or auxiliary oil pump, and a device for controlling the target volumetric flow rate to reduce the target volumetric flow rate to at least the currently deliverable actual volumetric flow rate, if the currently deliverable actual volumetric flow rate is below the current target volumetric flow rate.
摘要:
A hydraulic system in motor vehicles with at least one hydraulically actuated clutch, which entails minimized control complexity for supplying the clutch with hydraulic oil and which takes up less structural space. These characteristics are achieved essentially in that the pressure control of the hydraulically actuated clutch is effected directly and exclusively by an electrically driven and electronically controlled oil pump.

摘要:
A hydraulic system (1) for a transmission with a starter clutch is described. The hydraulic system (1) is designed to comprise a primary circuit (24) and a secondary circuit (5). A cooling system (9) for the starter clutch, a radiator (7) for hydraulic fluid and a lubricant supply (10) for the transmission are integrated into the secondary circuit (5), where the radiator (7) is arranged upstream from the cooling system (9) for the starter clutch. A volume flow of the hydraulic fluid through the radiator (7) can be limited by way of a controllable bypass line (11), which opens up into the secondary circuit (5) downstream from the radiator (7) and upstream from the cooling system (9) for the starter clutch.
