  • Patent number: 9885406
    Abstract: The disclosure describes a hydrokinetic torque coupling device for a motor vehicle. The coupling device includes a torque input element (11) intended to be coupled to a crankshaft (1), an impeller wheel (3) rotationally coupled to the torque input element (11) and able to hydrokinetically drive a turbine wheel (4). The turbine wheel, in turn, drives a torque output element (8) intended to be coupled to a transmission input shaft (2). The device further includes a clutch (10) able to rotationally couple and uncouple the torque input element (11) and the torque output element (8) between engaged and disengaged positions. When the clutch is in an engaged position, torque passes from the torque input element (11) to the torque output element (8) through an included damper system (18, 22).

  • Patent number: 9845833
    Abstract: A fan clutch assembly includes several features. A first feature relates to a lubrication passage that runs through the clutch package and has a return collection passage that extends through the operating piston. As a result, pitot tubes employed behind the piston may not be necessitated. Additionally, an anti-tamper device may be installed on the lead screw body to prevent adjustment of the fan hub and unintentional adjustment of the load carried on various bearings contained within the fan clutch assembly. Additionally, to position the speed sensor appropriately, a transfer shaft is provided that extends from the fan hub and/or lead screw back to the backside where a sensor is provided. This transfer shaft can be adjusted to precisely locate the sensor target relative to the sensor.

  • Patent number: 9845836
    Abstract: A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.

  • Patent number: 9845832
    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: 9815472
    Abstract: A braking force control apparatus for a saddle ride vehicle includes a transmission controller which reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel, a clutch device which connects—disconnects the driving force between the engine and the transmission, a brake device which generates braking force on the drive wheel, and a sensor which detects a state of the transmission. The transmission switches between a neutral state and an in-gear state, and when the sensor detects that the transmission is switching from the neutral state to the in-gear state, the controller causes the brake device to generate braking force on the drive wheel, and then releases the braking force upon completion of the switching to the in-gear state.

  • Patent number: 9784352
    Abstract: A lock-up device for a torque converter is disposed between a front cover coupled to an engine-side member and a torque converter body and directly transmits a torque from the front cover to a turbine of the torque converter. The lock-up device includes a clutch portion to transmit the torque from the front cover to an output side. The lock-up device includes an intermediate member in a power transmission path between the clutch portion and the turbine. An input-side damper mechanism mounted between the clutch portion and the intermediate member attenuates variation in rotational speed. An output-side damper mechanism mounted between the intermediate member and the turbine generates a hysteresis torque larger than a hysteresis torque of the input-side damper mechanism and attenuates variation in rotational speed. The lock-up device also includes a dynamic damper device coupled to the intermediate member and that attenuates variation in rotational speed.
