  • Publication number: 20130130811
    Abstract: Provided is a sliding ball type constant velocity joint for a vehicle, which can minimize vehicle vibration by forming a track groove pair by two track grooves of an outer race and an inner race to reduce a contact area between the inner race and a cage, and can reduce the manufacturing cost by reducing the number of processing steps of the cage by forming the number of windows of the cage to half that of balls.

  • Publication number: 20130123027
    Abstract: Provided is a ball type constant velocity joint for a vehicle. The ball type constant velocity joint includes an inner race installed at an end of a shaft, an outer race installed outside the inner race, a plurality of hails for transmitting rotational power of the inner race to the outer race, and a cage having windows for supporting the balls, wherein a ball track of the outer race is divided into two sections consisting of an outer race radial track and an outer race linear track contiguous to the outer race radial track, and when a joint angle is not created, a rotation center of the outer race radial track and a rotation center of the inner race linear track are positioned at the same point on a vertical center axis and have the same vertical offset amount.

  • Publication number: 20130116056
    Abstract: An angled offset ball type constant velocity joint for a vehicle, which can enhance the strength of the joint by compensating for a contact surface pressure between an outer race groove and a ball while maintaining an outer diameter of the outer race by making rotation centers of the outer race and the inner race positioned to be symmetrical with respect to each other by an offset angle. The angled offset ball type constant velocity joint includes an inner race connected to an end of a shaft, an outer race installed outside the inner race, a plurality of balls for transmitting a torque of the inner race to the outer race, and a cage having windows for supporting the respective balls, wherein a rotation center of an outer race ball track is symmetrical with a rotation center of an inner race ball track by an offset angle.

  • Publication number: 20120309546
    Abstract: Provided is a sliding ball type constant velocity joint for a vehicle, and more particularly, to a sliding ball type constant velocity joint for a vehicle, which can absorb idle vibration generated from the vehicle during idling by creating a clearance between an outer spherical surface of an inner race and an inner spherical surface of a cage. The sliding ball type constant velocity joint includes a shaft which receives rotational power from an engine and rotates, an outer race which is installed at an end of the shaft and having grooves formed therein, an inner race installed in the outer race, a plurality of balls for transmitting the rotational power of the outer race to the inner race, and a cage for supporting the balls, wherein a center of a radius of an outer spherical surface of the inner race is formed at a different location from a center of a radius of an inner spherical surface of the cage.
