| 20120073931 | CLUTCH APPARATUS FOR AUTOMATIC TRANSMISSION - A clutch apparatus for an automatic transmission makes it possible to reduce the number of parts, the weight, and manufacturing costs. Centrifugal hydraulic pressure due to operation oil is not generated in an operational hydraulic chamber when a clutch does not operate, that is, the operation oil is not supplied to operational hydraulic chamber, such that malfunction in which a clutch piston moves to a spring seat does not occur, and a balance hydraulic chamber and balance piston are not required. The clutch apparatus for an automatic transmission may include an operational hydraulic pressure supply hole formed at a boss portion of a retainer to be connected with an operational hydraulic chamber formed between the retainer and a clutch piston; and a sealing member disposed in a sealing groove formed in the clutch piston, making a gap between the retainer and the sealing member when a clutch does not operate, that is, operation oil is not supplied to the operational hydraulic chamber, and making the sealing groove and retainer in close contact when the clutch operates, that is, the operation oil is supplied to the operational hydraulic chamber such that the operational hydraulic chamber is kept hermetically sealed. | 03-29-2012 |
| 20140166427 | CLUTCH SEPARATOR PLATE - A novel clutch separator plate is disclosed. The improved clutch separator plate incorporates openings which pass over the friction pads of a friction plate to improved thermal stability, reduce drag and provide consistent and positive engagement. | 06-19-2014 |
| 20140110214 | HYDRAULIC FILLER FOR A TRANSMISSION - A hydraulic fluid filler for a motor vehicle transmission includes a set of holes through which respective springs of a spring pack extend. The filler is generally positioned adjacent to a single retainer ring or between two retainer rings associated with the spring pack. In some implementations, the filler floats between the two retainer rings, while, in other implementations, the filler is securely attached to one or both of the retainer rings. The filler reduces the volume of one of two cavities, chambers, or cylinders positioned on opposite sides of a piston that selectively interacts with a clutch assembly to engage or disengage the clutch assembly. Reducing the volume of one of the cavities, chambers or cylinders effectively reduces the time period the spring pack is then able to apply a restoring force to the piston. | 04-24-2014 |
| 20110297504 | CLUTCH DEVICE - A clutch device which transmits torque by causing multiple friction engagement elements to engage with each other by use of a clutch connection/disconnection member caused to operate by an electric actuator includes: an elastic member disposed between the clutch connection/disconnection member and the multiple friction engagement elements; position detection means for detecting a position of the clutch connection/disconnection member; and controlling means for controlling an operation of the electric actuator on the basis of the position of the clutch connection/disconnection member detected by the position detection means. Thus, the position of the clutch connection/disconnection member (i.e. a stroke amount of the elastic member) and a torque transmission capacity of the clutch device have a linear relationship with each other. Hence, the torque transmission capacity of the clutch device can be accurately controlled by the electric actuator. | 12-08-2011 |
| 20130092500 | CLUTCH COVER ASSEMBLY - In a clutch cover assembly, accurate abrasion compensation is constantly enabled by stabilizing the actuation of an abrasion amount detecting mechanism.

The abrasion amount detecting mechanism is a mechanism having a plurality of meshing positions and includes a mobile detecting member configured to release meshing in a first meshing position and move to a second meshing position when the abrasion amount of a friction member reaches a predetermined amount. The abrasion tracking mechanism moves the diaphragm spring to an initial posture side thereof in accordance with the displacement of the mobile detecting member. | 04-18-2013 |

| 20090139823 | Handlebar clutch-lever assist - Clutch lever assist for capturing and holding a motorcycle clutch lever in its clutch-disengaged position. The assist mounts on the handlebar and has a catch that pivots between a capture position and a release position. The motorcycle operator pulls the clutch lever in toward the clutch-disengaged position and uses a finger or thumb to urge the catch to its capture position. Once the clutch lever is captured, the operator may relax his grip. The catch will hold the clutch in its clutch-disengaged position. Pulling the clutch lever in toward the handlebar slightly, beyond the capture portion of the catch, releases the catch, which is spring-biased and automatically springs back to its release position. The clutch lever is now under operator control. A safety lock is provided optionally on the clutch lever assist, to lock the catch into the clutch-lever engaging position. | 06-04-2009 |
