    摘要: A torque transfer apparatus for a transmission includes a rotatable friction clutch pack including a first friction plate that is contiguous to a second friction plate, with the first friction plate coupled to a first transmission element and the second friction plate coupled to a second transmission element. A Belleville spring device is configured to urge the first friction plate to engage the second friction plate to effect torque transfer therebetween when a hydraulically-activated piston is deactivated. The hydraulically-activated piston is configured to urge the second periphery of the Belleville spring device away from mechanical contact of the first friction plate when the hydraulically-activated piston is activated.

    摘要: An actuator shifts a selectable one-way clutch (SOWC) between a plurality of operating modes. A first spring has a preload compression that is equivalent to a first start pressure. A second spring, disposed adjacent to the first spring, has a preload compression that is equivalent to a second start pressure. A plunger movably contacts the first spring and a slide plate movably extends from the plunger. The slide plate engages the SOWC such that the SOWC shifts between the operating modes in response to movement of the slide plate. The first spring is compressible from beyond the preload compression to a first stop position as the pressure is increased from the first start pressure to a first stop pressure. The second spring is compressible from beyond the respective preload compression to a second stop position as the pressure is increased from the second start pressure to a second stop pressure.

    摘要: An actuator is adapted to selectively extend and retract a bumper member, the actuator is mounted at least partially within a tubular frame rail member of the motor vehicle. The main frame rail member may be of a standard length or of a shortened length. By mounting the actuator inside the tubular frame rail member, the bending stiffness is more effectively impacted by the outer tube of the actuator. An additional tubular frame rail member is optionally attached to the main tubular frame rail member. The actuator is mounted at least partially within the tubular frame rail member and at least partially within the additional tubular frame rail member. The wall thickness and cross-sectional shape of the additional tubular frame rail members may be adjusted to obtain a desired bending stiffness including the effect of the outer tube of the actuator.

    摘要: A corrosion-resistant spinneret, suitable for spinning filaments of poly(p-phenylene terephthalamide) from a viscous solution of the polymer in 98-100 percent sulfuric acid, is prepared from a plate of tantalum alloy or stainless steel which is clad on one face with a layer of pure tantalum. A spinneret blank is formed, counterbores are drilled through the plate and partially into the tantalum layer, the blank is annealed, spinneret capillaries are formed from the counterbores through the tantalum layer to the exit face of the spinneret, the face is polished to remove protrusions, and the face is hardened by heat-treatment in nitrogen. Uniform capillaries having a diameter of about 0.002 inch (0.05 mm) and a length greater than about 0.005 inch (0.13 mm) can be formed in spinnerets without breaking tools used in their production.
