  • Patent number: 11167739
    Abstract: A method of manufacturing vehicle brake boosters includes load testing a plurality of reaction discs and sorting the load-tested reaction discs into multiple, separate batches based on the load test results. A first batch of plunger plates is formed to an axial length to correspond with a first of the separate batches of reaction discs. A first batch of the vehicle brake boosters is assembled with a first one of the multiple, separate batches of reaction discs and the first batch of plunger plates to achieve a target jump-in force. A second batch of plunger plates is formed to an axial length to correspond with a second one of the separate batches of reaction discs. A second batch of the vehicle brake boosters is assembled with a second one of the multiple separate batches of reaction discs and the second batch of plunger plates to achieve the target jump-in force.

  • Publication number: 20070045066
    Abstract: A wheel hub for a corner assembly on a vehicle wherein a wheel and a rotor for a brake system are attached to the wheel hub. The wheel hub has a cylindrical body with a peripheral surface thereon having a flange to which the rotor and the rim of a wheel are attached and a bearing surface that receives a bearing fixed to a stationary member to establish a perpendicular alignment between first and second engagement faces on the rotor and friction members carried by a caliper. A attachment clip attached to the flange resiliently urges the rotor toward the flange to sustain the perpendicular alignment even though the rotor may axially translate during a brake application.

  • Publication number: 20060151266
    Abstract: A corner assembly for a vehicle having a wheel hub and a rotor wherein the rotor may freely translate axially with respect to the wheel hub during a brake application and as a result any vibrations created on the engagement of friction pads with the rotor are not introduced into a stationary support by way of the wheel hub not sensed by a person in the vehicle.

  • Publication number: 20060096097
    Abstract: A module corner assembly wherein a wheel hub is permanently attached to a knuckle and various surfaces on the wheel hub and knuckle are machined in a same fixture utilized in holding the knuckle to deform an end on the wheel hub against a cone of a bearing. When a rotor is thereafter attached to the wheel hub it is also machined in the same fixture such that a perpendicular relationship is established between the axis of the wheel bearing and braking surfaces on the rotor and as a result a desired lateral run out relationship is achieved between the axis of the bearing and rotor surfaces.

  • Publication number: 20060096096
    Abstract: A knuckle (16) for a corner assembly (10, 210, 310) wherein a cylindrical body (18) has an outboard race (39) and an inboard race (45) located therein for correspondingly receiving a first roller assembly (52) and a second roller assembly (94) carried by a wheel hub (56) such that brake engagement surfaces (12a) and (12b) on a rotor (12) are located in a parallel relationship with faces on a friction members (14a) and (14b) associated with caliper (14) and perpendicular with the axis of the wheel hub (56) to obtain a desired lateral run out relationship between the rotor (12) and the axis of the first (52) and second (94) roller assemblies retained in the wheel hub (56).
