摘要： A monitoring device and a method for operating an idling automatic transmission of a motor vehicle having a torque converter which includes at least one pump wheel and a turbine wheel that are designed to transmit torque hydrodynamically from one to the other. The method includes at least the following steps of: determining a rotational speed of the turbine wheel; determining a load on the motor of the motor vehicle; and recognizing whether there is a blockage in the drive-train of the motor vehicle or whether the torque converter is running dry, as a function of the turbine rotational speed and the motor load detected.

摘要： A torque converter, including: a cover arranged to receive torque; an impeller; a turbine; a stator; and a lock-up clutch including a piston plate, a first plate, a second plate axially disposed between the cover and the first plate, and a rivet non-rotatably connecting the first plate to the second plate, the rivet being a component distinct from the first plate and the second plate. The cover and the piston plate define at least a portion of a first pressure chamber. The first plate and the second plate define at least a portion of a second pressure chamber. The first pressure chamber and the second pressure chamber are arranged to receive and expel a fluid to axially displace the piston plate to open and close the lock-up clutch.

摘要： An apparatus and methods for a double coast engagement diaphragm spring for a torque converter are provided. The double coast engagement diaphragm spring includes first and second coast engagement diaphragm springs. The first coast engagement diaphragm spring exerts a first, continuous axial thrust onto a turbine comprising the torque converter. The second coast engagement diaphragm spring applies a second axial thrust onto the turbine only during coasting conditions. A drive flange includes ramps for engaging the second coast engagement diaphragm spring during coasting conditions and causing the second coast engagement diaphragm spring to apply the second axial thrust onto the turbine. A retainer plate disengages the second coast engagement diaphragm spring during drive conditions. A spacer ring between the first coast engagement diaphragm spring and the second coast engagement diaphragm spring causes the first and second coast engagement diaphragm springs to operate in series.

摘要： A power transmission device includes a torque converter device, a first hydraulic pump, a first oil channel, a second oil channel, a third oil channel, a second pressure control valve, and a controller. The torque converter device has a torque converter and a lock-up clutch. The first oil channel supplies hydraulic fluid from the first hydraulic pump to the torque converter. The second oil channel drains hydraulic fluid from the torque converter. The third oil channel communicates with the first oil channel and the second oil channel. The second pressure control valve is disposed in the third oil channel. The controller sets the second pressure control valve to an open state when the lock-up clutch is in an engaged state.

摘要： A hybrid drive module is disclosed. An exemplary embodiment of the present invention provides a hybrid drive module that selectively transmits torque transmitted from an engine and a motor to a transmission including a housing disposed between the engine and the transmission, a drive shaft rotatably mounted inside the housing in a radial direction with its one end portion toward the engine based on an axial direction protruding from the housing and to which torque of the engine is inputted, a rotor hub provided within the housing and mounted with a rotor of the motor on its radially outer side, and in which a hub plate part integrally extending toward the drive shaft and rotatably connected to the other end portion of the drive shaft toward the transmission based on the axial direction is formed on its radially inner side, a rotor hub ridge, an inner circumferential surface of which is rotatably supported by the housing based on the radial direction and an external circumferential surface of which is fixed to the rotor hub based on the axial direction at the side of the engine, an engine clutch disposed at the engine side in the axial direction with the hub plate part interposed therebetween, and configured to directly connect the drive shaft and the rotor hub to selectively transmit the torque of the engine to the rotor hub, and a torque converter disposed at the side of the transmission in the axial direction with the hub plate part interposed therebetween to be connected to the rotor hub, and configured to multiply the torque of the engine, torque of the motor, or the torque of the engine and the motor when a vehicle is initially driven, or to transmit it to the transmission in a ratio of 1:1, wherein at least one fluid groove for supplying an operating fluid to the rotor to cool the rotor between the rotor hub and the engine clutch is formed on a surface of the hub plate part toward the engine clutch based on the axial direction.

摘要： A torsional vibration damper having improved vibration damping performance. The torsional vibration damper comprising: a pendulum vibration damper that damps pulsation of engine torque by an oscillating motion of an inertia body in response to the pulsation of the torque; and an engagement device that damps the amplitude of the pulsation of the engine torque by a relative rotation of rotary members. The pendulum vibration damper and the engagement device are arranged in order on a transmission route of the torque of the engine from a side at which the engine is disposed.
