  • Publication number: 20020128078
    Abstract: A constant velocity universal joint includes an inner roller and a trunnion. The inner roller has a chamfered portion formed by an inclined surface inclined at an angle not less than an assembling angle &thgr;. The inclined surface extends from a starting point defined by a crossing point of a spherical recess of the inner roller and a short radius r of an elliptic cutout formed on the inner roller.

  • Publication number: 20020128077
    Abstract: A variety of cutout surfaces are formed on trunnions by cutting out parts of a spherical surface of each of the trunnions, to which no torque is applied. The cutout surfaces comprise a pair of opposite flat surface sections, bores, recesses or wide flat surfaces, and curved surface sections, for example.

  • Patent number: 6435972
    Abstract: A constant velocity universal joint comprises a plurality of trunnions which are formed to be spherical, sliding surfaces which extend in a flat configuration along an axial direction of an outer cup, and pairs of slipper members having one side surfaces which are formed with recesses for making contact with spherical surfaces of the trunnions and the other side surfaces which are formed with flat surfaces to make contact with the sliding surfaces, wherein the pair of slipper members are provided slidably with respect to the sliding surface and the spherical surface of the trunnion.

  • Publication number: 20020094875
    Abstract: When forcibly mounting a fixture attached with a joint boot on an outer circumferential surface of an outer cup, a thick-walled section is pressed between an inclined surface of the outer cup and an annular stepped section of the fixture. Accordingly, the thick-walled section is elastically deformed and in close contact with the inclined surface for effecting sealing function.

  • Patent number: 5725433
    Abstract: A housing has, on an outer circumferential surface thereof, a circumferential surface area, a toothed surface area complementary in shape to grooves and teeth of a boot of rubber, and a stopper engagable by tip ends of the boot of rubber and a boot of synthetic resin. The circumferential surface area, the toothed surface area, and the stopper are successively arranged in the order named in the direction in which the boots are installed onto a rotary joint. The housing has an outside diameter at the circumferential surface area which is equal to or greater than an inside diameter of the boot of synthetic resin. The circumferential surface area, circumferential teeth of the toothed surface area, and the stopper are progressively higher radially outwardly in the order named.

  • Patent number: 4828087
    Abstract: An inertia lock type synchronous clutch mechanism wherein a shifting sleeve is splined to a clutch hub and has circumferentially spaced cam portions on each axial side for engaging axially convex portions of an elastic ring on each side which convex portions fit within circumferentially spaced notches formed in the rim of the clutch. The convex portions of the elastic ring engage a blocking ring to cause frictional engagement with the selected gear and synchronize the rotation of that gear and the clutch hub for smooth engagement between the shifting sleeve and that gear.

  • Patent number: 4381682
    Abstract: An automatic latch for preventing inadvertent shifting of a manually controlled automotive transmission into reverse drive condition from a forward drive condition, includes a latch member which is moved into an operative blocking position upon the movement of a gear shift lever in one direction to engage a forward drive gear and which is moved out of its blocking position upon return of the gear shift lever to a neutral position, the latch, when in an operative position, blocking movement of the gear shift lever directly from engagement of said forward drive gear to engagement of a reverse drive gear.
