  • Patent number: 8052536
    Abstract: To prevent inverting of a mountain portion of a bellows member when a rotating shaft is angularly displaced, the boot includes a bellows member with large and small diameter mounting members. A first mountain portion nearest the large diameter mounting member rises from the large diameter mounting member. A length (L1) between a top of the first mountain portion and a bottom at the large diameter mounting member side is not more than a length (L2) between the inner peripheral position of the bottom and an end portion of an outer ring at the rotating shaft side. A first valley portion adjacent to the first mountain portion is positioned at the rotating shaft side from the end part.

  • Publication number: 20110256941
    Abstract: Provided is a boot, which is excellent in durability, for a constant velocity universal joint and provided is a constant velocity universal joint capable of using such a boot, the boot being capable of conforming even to operation at high angles while being flexibly deformed and capable of effectively distributing and equalizing an interference pressure between peak portions, an interference pressure between valley portions and a shaft, and stress concentration onto the valley portions, and contributing to enhancement of abrasion resistance and fatigue resistance. A bellows section (15) of the boot includes three or more peak portions (7) and three or more valley portions (6) arranged alternately with the peak portions (7) along an axial direction. A radially outer portion of each of the peak portions (7) in vertical cross-section of the boot is formed into a round shape.

    Abstract: A disc brake for a motor vehicle is provided. The disc brake includes a brake disc, a brake caliper configured to straddle the brake disc, a tappet carried by the brake caliper and arranged to push a brake pad against the brake disc, and a bellows provided between the brake caliper and the tappet to seal a gap between the brake caliper and the tappet. A layer of flexible thermal insulation material may be provided between the bellows and the tappet. The layer of flexible thermal insulation material is configured to protect an outer surface of the bellows facing the brake pad from exposure to heat. Alternatively, the bellows may include a layer of flexible thermal insulation material on which an elastomer layer is formed. The layer of flexible thermal insulation material is configured to face the brake pad.

  • Patent number: 7967687
    Abstract: A flexible section is provided between a small-diameter tube section and a bellows section of a boot for a joint, and the flexible section has a greater flexibility than the small-diameter tube section. When a spline shaft is displaced so as to incline relative to a constant velocity joint, deformation stress acting in the boot is relaxed by allowing the flexible section to deflect (bend). This inhibits the inner wall surface of the small-diameter tube section from separating from the sidewall surface of the spline shaft.

  • Patent number: 7955179
    Abstract: To make a bellows section of a boot to be flexibly and repeatedly deformable without deterioration in durability, to thereby reduce rotational resistance when a joint angle is large, the boot has the bellows portion where three or more circumferentially extending crest portions and root portions therebetween are alternately formed. A large-diameter attaching portion is formed at one end of the bellows portion. A small-diameter attaching portion is formed at the other end. A rising wall closest to the large-diameter attaching portion and a rising wall closest to the small-diameter attaching portion have smaller wall thickness than other portions of the bellows section. A ratio (t1/t2) of the thickness (t1) of the rising walls to the thickness (t2) of the other portions of the bellows portion is set to 0.6?t1/t2<1.0.

  • Patent number: 7950669
    Abstract: The invention provides a method that can be applied, for example, to seal a constant velocity joint. The invention includes a method comprising the steps of substantially sealing the constant velocity joint with the primary boot which includes first and second ends, fixedly associating the first end of the primary boot with the constant velocity joint, and slidably associating the second end of the primary boot with the shaft which extends from the constant velocity joint. In one aspect, the invention includes a primary boot having a body defining a substantially smooth interior surface and a secondary boot associated with the primary boot and spaced from the interior surface. In another aspect, the invention includes a constant velocity joint having an outer joint member, an inner joint member positioned in the outer joint member, a plurality of ball members positioned between said outer and inner joint members, and a shaft engaged with and extending from the inner joint member.
