  • Publication number: 20230287959
    Abstract: A centrifugal pendulum device is provided having a weight carrier disc an opening and guide tracks arranged on a radially outer region thereof and including damper spring openings in a radially inner region thereof. A centrifugal weight is disposed displaceably on the weight carrier disc, with the centrifugal weight including two side elements that each include weight guide tracks, and spacing bolts arranged between the two side elements. At least one of the spacing bolts extends through the opening of the weight carrier disc, and the centrifugal weight is guided displaceably on the weight carrier disc by roller elements that run on the guide tracks and the weight guide tracks. In order to reduce weight and provide additional flexibility, the weight carrier disc comprises a first plate that includes the radially inner region that is connected to at least one second plate that includes the radially outer region.

  • Patent number: 11719318
    Abstract: A stator assembly for a torque converter includes a body and a washer. The body is rotatable about an axis and has a cavity defined by an axial wall radially spaced from the axis and a radial wall extending radially inward from the axial wall. The washer is disposed in the cavity and is configured to be compressed against the radial wall. The washer includes a base and a plurality of circumferentially spaced from each other and extending radially outward from the base. The plurality of tabs are configured to non-rotatably connect to the axial wall.

  • Publication number: 20220263176
    Abstract: A battery assembly that includes a plurality of cells and a mounting arrangement having two side plates, with the plurality of cells arranged between the two side plates with sides of the cells facing one another. At least two bolts extend between the side plates, with each bolt having a head on one end and a threaded engagement on an opposite end. The at least two bolts are configured to clamp the side plates and the cells together. For each of the bolts, a diaphragm spring is located at least one of between the head and an adjacent one of the side plates or between the threaded engagement and an adjacent one of the side plates. The diaphragm spring is configured to apply a force over an effective range of the diaphragm spring such that the side plates constant force is applied to the cells during expansion and contraction.

  • Patent number: 11359708
    Abstract: A flexplate for a motor vehicle drivetrain includes a carry plate configured for being connected to an engine crankshaft and a drive plate. The drive plate and the carry plate are separate components attached directly via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component. A method of constructing a flexplate for a motor vehicle drivetrain includes stamping a carry plate configured for being connected to an engine crankshaft; stamping a drive plate separate from the carry plate; and attaching the drive plate and the carry plate directly together via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component.
