Description

This application claims the benefit of US Provisional Patent Application No. 61 / 463,208, filed Feb. 14, 2011, and was filed on Feb. 10, 2012. Claims priority of US patent application Ser.

  The present invention relates to an electromechanical assembly that controls the mode of operation of a coupling device, such as a controllable one-way clutch (OWC).

A typical one-way clutch (OWC) consists of an inner ring, an outer ring, and a locking device between the two rings. A one-way clutch is designed to lock in one direction and allow free rotation in the other direction. Two types of one-way clutches often used in vehicle automatic transmissions,
A roller type consisting of a spring-suspended roller between the inner race and outer race of the one-way clutch (the roller type is also used without a spring in some applications),
A sprag type consisting of an asymmetric wedge arranged between the inner race and the outer race of the one-way clutch,
There is.

  One-way clutches are commonly used in transmissions to prevent interruption of drive torque (ie, power flow) during certain gear shifts and to enable engine braking during coasting.

  Controllable or selectable one-way clutches (ie, OWC) are different from conventional one-way clutch structures. A second lock member set is added to the selectable OWC along with the slide plate. An additional lock member set with a slide plate adds a plurality of functions to the OWC. Depending on design requirements, the controllable OWC can form a one-way or two-way mechanical connection between rotating or stationary shafts. Further, depending on the design, the OWC can be overrunning in one or both directions. A controllable OWC includes an externally controlled selection or control mechanism. The selection mechanism can be moved between two or more positions corresponding to various operating modes.

  US Pat. No. 5,927,455 discloses a bi-directional overrunning pawl clutch, US Pat. No. 6,244,965 discloses a planar overrunning coupler, and US Pat. , 290,044 discloses a selectable one-way clutch assembly for use in an automatic transmission.

  U.S. Pat. Nos. 7,258,214 and 7,344,010 disclose overrunning coupler assemblies and U.S. Pat. No. 7,484,605 describes overrunning radials. A coupler assembly or clutch is disclosed.

  A properly designed controllable OWC can have near zero parasitic losses in the “off” state. The OWC can also operate with an electrical mechanism, no complexity, and no parasitic losses in the hydraulic pumps and valves.

  A linear motor is an electric motor whose stator and rotor do not "rotate", so the linear motor does not generate torque (rotation) but generates a linear force along its length. The most common mode of operation is similar to a Lorentz-type actuator where the applied force is linearly proportional to the current and magnetic field. US 2003/0102196 discloses a bidirectional linear motor.

  Metal injection molding (MIM) is a metalworking process in which fine metal is mixed with a certain amount of binder material to form a feedstock that can be handled by plastic processing equipment through a process known as injection molding. The The molding process allows complex parts to be molded in large quantities in a single operation. The final product is a component article that is typically used in various industries and applications. The fluidity of the MIM feed is defined by a physics called rheology. Current equipment capabilities require processing to be retained while limiting to products that can be molded using a normal amount of 100 grams or less per “shot” into the mold. Rheology allows this "shot" to be distributed in multiple cavities, and is therefore a small and complex mass that would otherwise be very expensive to manufacture by alternative or legacy methods Cost-effective for production. The various metals that can be introduced into the MIM feed are called powder metallurgy, and these include the same alloying compositions found in industry standards for common and rare metal applications. Next, an adjustment operation is performed on the molded shape, the binder material is removed, and the metal particles coalesce into a desired state as a metal alloy.

  The clevis fastener is a three-part fastener system consisting of a clevis, a clevis pin, and a tang. A clevis is a U-shaped part having a hole at the end of a bifurcated portion for receiving a clevis pin. A clevis pin is similar to a bolt, but only partially threaded or unthreaded and has a side hole for a set pin. The protrusion is a part that fits in the middle of the clevis and is held in place by the clevis pin. A simple clevis combination with a pin is usually referred to as a shackle, but a pinned clevis is just one of the various forms that a shackle can take.

  Clevis is used in agricultural machinery, sailboat rigging, and various fasteners used in the automotive, aircraft, and construction industries. Clevis is also widely used to attach control surfaces and other accessories to model aircraft servo mechanisms. As part of the fastener, clevis provides a way to allow rotation on some axes while prohibiting rotation on other axes.

  In this application, the term “coupler” means that one of the plates is drivably connected to the torque delivery element of the transmission and the other plate is drivably connected to another torque delivery element, or the transmission. It should be construed to include a clutch or brake that is fixed and held stationary relative to the housing. The terms “coupler”, “clutch”, and “brake” can be used interchangeably.
