  • Patent number: 10563712
    Abstract: A transmission includes at least one shift element for which both the apply pressure and the release pressure are actively controlled. A controller adjusts the torque capacity of the shift element by varying the apply pressure and the release pressure in a coordinated fashion. During particular events, such as a shift event with the shift element as oncoming element or holding element, both the apply pressure and the release pressure are monotonically increased, mitigating the effect of hysteresis.

  • Patent number: 10533616
    Abstract: A vehicle transmission includes a transmission shaft, a friction element assembly mounted on the transmission shaft, a piston assembly for actuating the friction element assembly, a snap ring for retaining the friction element assembly and a mounting groove formed in the transmission shaft. The snap ring is installed into the mounting groove by expanding the snap ring and then allowing the snap to contract and enter the mounting groove. The mounting groove is located such that the snap ring could exit the mounting groove upon expansion of the snap ring due to a centrifugal force. Accordingly, various arrangements are provided to prevent the snap ring from leaving the mounting groove after installation.

  • Patent number: 10138955
    Abstract: A clutch for an automatic transmission includes a tubular housing surrounding a clutch pack and having an end for engaging with a pressure plate. An annular separator spring on the end provides a biasing force against the pressure plate. A plurality of depressible pins are disposed in the housing and are located radially outward from the annular spring for inhibiting radial movement of the separator spring.

  • Patent number: 10054223
    Abstract: A friction element assembly for a transmission of a motor vehicle includes a set of plates and friction members. A piston assembly is configured to apply a force to the set of plates and friction members. The friction element assembly also includes a housing with a mounting groove; a pressure plate having first and second edges; and a snap ring positioned in the mounting groove. The snap ring is positioned such that first edge of the pressure plate contacts the snap ring and the second edge of the pressure plate extends across a portion of the snap ring. The snap ring is L-shaped and includes a leg portion that contacts the second edge of the pressure plate when the piston assembly applies a force to the set of plates and friction members.

  • Patent number: 10041591
    Abstract: A park-by-wire system uses a single spring to bias the system towards park and to permit a ratcheting feature which delays the engagement of park until vehicle speed drops below a threshold. A cam slides with respect to a rod. A stop on the rod limits travel in one direction. The spring biases the cam toward the stop but compresses as necessary to allow the cam to move during ratcheting operation. The spring reacts against the housing. Acting through the cam and the stop, the spring biases the rod toward the park position. The design limits the number of components that move during ratcheting operation. Specifically, the rod and actuator do not oscillate during ratcheting operation.

  • Patent number: 9909630
    Abstract: A clutch includes a piston, backing plate, spring, and spring retainer. The piston and the backing plate define a balance chamber therebetween. The piston has a protrusion that extends into and defines a pocket in the chamber. The spring is disposed within the pocket and is configured to disengage the piston from a clutch pack. The spring retainer is disposed between the spring and the backing plate. The retainer extends from the backing plate and into the chamber beyond an end of the protrusion.

  • Publication number: 20180058572
    Abstract: A multiplexed sensor for determining pressures of two different chambers of a clutches is provided, utilizing real-time pressure of a balance chamber of a clutch to control that clutch. The transmission includes a balance dam fixed with respect to a clutch housing. The clutch is compressible in a direction away from the balance dam by a piston. The balance dam and the piston define a balance chamber therebetween. An apply chamber is located on the opposite side of the balance dam, and is configured to apply or supply pressurized fluid to the clutch pack. A multiplexed pressure sensor is in fluid communication with the balance chamber and the apply chamber. A controller is programmed to control the clutch based on a pressure in the apply chamber and the balance chamber depending on, for example, which pressure is greater.

  • Patent number: 9810315
    Abstract: A vehicle includes a transmission having a fluid pump, a high pressure fluid circuit, a low pressure fluid circuit, and an accumulator. The vehicle also includes a controller that is programmed to, in response fluid demand exceeding a capacity of the pump, isolate the low pressure circuit from the pump.
