Abstract: A steering assembly comprises: a steering rack configured to be linearly movable; a nut rotatably coupled to the steering rack, wherein the steering rack linearly moves in association with rotation of the nut; a bearing configured to support the rotation of the nut, the bearing comprising an outer race having a flanged part protruding from an outer surface of the outer race of the bearing; and a rack housing accommodating at least a portion of the steering rack, the nut, and the bearing, and having a groove recessed from an inner surface of the rack housing. The flanged part protruding from the outer surface of the outer race of the bearing is disposed in the groove recessed from the inner surface of the rack housing.

Abstract: A brake assembly comprises a rotatable part configured to be rotatable by an actuator and a translatable part operably coupled with the rotatable part and configured to be axially translatable relative to the rotatable part to move the brake pad according to rotation of the rotatable part; and a bearing assembly configured to support the rotatable part. The bearing assembly comprises: an inner race comprising a forward inner race portion and an aft inner race portion; an outer race; and rollable balls. The forward inner race portion located closer to the brake pad than the aft inner race portion is made of a different and/or stronger material from and/or than the aft inner race portion located farther from the brake pad than the forward inner race portion, and/or is smaller than the forward inner race portion located farther from the brake pad than the aft inner race portion.

Abstract: A brake assembly comprises: a rotatable part configured to be rotatable by an actuator; a translatable part operably coupled with the rotatable part, and configured to be axially translatable relative to the rotatable part to move a brake pad according to rotation of the rotatable part; and a bearing assembly comprising: an inner race provided on an outside of the rotatable part, the inner race having first and second inner shoulders and an inner curved surface; an outer race having first and second outer shoulders and an outer curved surface; and rollable bodies movably disposed between the inner race and the outer race. The first inner shoulder of the inner race and/or the first outer shoulder of the outer race are asymmetric to the second inner shoulder of the inner race and/or the second outer shoulder of the outer race, respectively.

Abstract: A retainer comprises a snap ring part substantially discontinuous-ring shaped with opposed ends defining a break to be fitted over an outer surface of a ball nut; and an outer race part of a ball return formed on an inner surface of the snap ring part to be coupled with an inner race part of the ball return, end portions of the outer race part of the ball return to be connected to openings of the ball nut for recirculating balls. The snap ring part is extended further than the end portions of the outer race part of the ball return around the outer surface of the ball nut such that the snap ring part retains the outer race part, formed on the inner surface of the retaining ring portion, on the outer surface of the ball nut to be coupled with the inner race part of the ball return.
