Document Type and Number:
WIPO Patent Application WO/2015/182981
Kind Code:
A1
Abstract:
Provided is a fixed ball-type joint for a vehicle, according to the present invention, comprising: an outer race that rotates about a first rotational axis and has an outer race track extending in the direction of the first rotational axis; an inner race that rotates about a second rotational axis that can be inclined to the first rotational axis and has an inner race track extending in the direction of the second rotational axis; balls provided between the inner and outer race tracks; and a cage that supports the balls. The outer race track includes a first curved track and a first linear track, wherein the first curved track is formed such that the center of curvature thereof is opposite to the first curved track with respect to the first rotational axis and is opposite to the first curved track with respect to an imaginary line that passes a connection portion between the first curved track and the first linear track and the center of rotation of the joint, and the first linear track is formed to be inclined to the first rotational axis. The inner race track includes a second curved track and a second linear track, wherein the second curved track is formed such that the center of curvature thereof is located on the second curved track side with respect to the second rotational axis and is opposite to the second curved track with respect to an imaginary line that passes a connection portion between the second curved track and the second linear track and the center of rotation of the joint, and the second linear track is formed to be inclined to the second rotational axis.
