  • Patent number: 11535241
    Abstract: A vehicle includes a transmission, an engine, a clutch, and a controller. The transmission has an input. The engine is configured to generate and deliver torque to the input. The clutch is configured to connect and disconnect the engine from the input, and to crank the engine during an engine start. The controller is programmed to, in response to a command to adjust a torque of the clutch during an engine start and a presence of first condition of the clutch, drive a clutch actuator pressure to a first desired value based on a first transfer function. The controller is further programmed to, in response to a command to adjust the torque of the clutch during the engine start and a presence of a second condition of the clutch, drive the clutch actuator pressure to a second desired value based on a second transfer function.

    Abstract: A friction device assembly structure for an automatic transmission includes a first friction device and an end play adjustment element. The first friction device includes a plurality of discs and a plurality of plates which are alternately arranged and configured such that a frictional force is created between the discs and the plates by the pressing force of a piston. The end play adjustment element is provided on an end of the first friction device to adjust an end play defined between the first friction device and the piston. The end play adjustment element is hollow such that an inner diameter thereof is greater than an outermost diameter of a second friction device which is provided inside the first friction device. Thereby, the end play adjustment element is able to be assembled without any interference from the second friction device.

    Abstract: A clutch device includes a first clutch, a second clutch, a diaphragm spring and an intermediate spring. The diaphragm spring transmits a pressing force to the first clutch and the second clutch. The intermediate spring applies a coupling maintaining force to the first clutch and the second clutch so that minimally power transmitted states of the first clutch and the second clutch are maintained while a pressing force is not being applied to the first clutch and the second clutch.

  • Publication number: 20130180818
    Abstract: A coupling apparatus for transmitting torque from a drive shaft to an output shaft includes two couplings with a respective primary part and secondary part. The primary and secondary parts are twistable to a certain extent relative to one another against the force of springs. Several carriers for carrying spring plates and support plates are arranged in a distributed manner over the circumference of the coupling. There is a locating pin between two screws for positioning a carrier, the locating pin being axially parallel to the screws. One coupling is in a drive connection with the drive shaft, and the other coupling is in a drive connection with the output shaft. Every carrier which can be inserted into a respective recess in the primary part or secondary part of the respective coupling forms a premounted spring unit together with the spring plates carried by the carrier.

  • Patent number: 8483898
    Abstract: A vehicle includes a clutch set, a tank with fluid, an auxiliary battery, an electric fuel pump, and a controller. The electric fluid pump delivers some of the fluid from the tank to a designated oncoming clutch of the clutch set. The controller calculates a predicted flow value for the oncoming clutch during the shift event, and selectively controls the speed of the pump using the predicted flow value during the shift event. The controller controls the pump using an actual flow value when the vehicle is not executing a shift event, i.e., when holding torque. The speed of the electric fluid pump is increased to a first calculated speed determined using the predicted flow value when the shift event is initiated and before filling of the oncoming clutch commences, and is reduced to a second calculated speed determined using the actual flow value when the shift event is complete.

  • Publication number: 20130153353
    Abstract: A multiple ratio transmission having an input shaft, an output shaft and oncoming clutch and off-going clutch for effecting ratio upshifts is provided. The transmission also includes a transmission controller configured for controlling shifts. During the torque phase of a ratio upshift, the controller increases input torque. Next, the controller estimates an oncoming clutch target torque. The controller controls a torque input to ensure the off-going clutch remains locked. The controller measures an actual transmission value for a torque transmitting element of the transmission and corrects the oncoming clutch target torque using the actual transmission value whereby an increasing torque for the oncoming friction element is achieved with minimal torque transients along the output shaft during the upshift.

  • Publication number: 20130153355
    Abstract: A wet clutch assembly has an inner housing configured for rotation with an input torque member to the clutch assembly. The inner housing has a series of splines to support a portion of the plates in a clutch pack. Each spline defines a single aperture in fluid communication with at least one plate of the clutch pack, and apertures on adjacent splines are offset to distribute cooling fluid nearly equally between friction surfaces. Uniform flow distribution ensures efficient use of cooling fluid and prevents overheating of plates receiving lesser fluid flow.
