    Abstract: Disclosed is a brake actuation unit for actuating a ‘brake-by-wire’ type brake system for a motor vehicle. The brake system includes a brake booster operable via a brake pedal mounted on a shaft and via an electronic control unit depending on the driver's request, and an element to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. Also included are a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and is formed of a simulator spring, which is arranged in terms of effect between a force-transmitting part connected to the brake pedal and a simulator housing, which is mounted on the shaft by means of two bearings. The simulator housing (22) includes a cylindrical area (26) for the accommodation of the two bearings (27, 28). This measure renders it possible to reduce the deformations that occur during actuation of the pedal travel simulator to a great extent.

  • Publication number: 20080085072
    Abstract: A taper bore bearing assembly permits variability in diameter of the rotating shaft. An annular cylinder is mechanically coupled to the rotatable shaft and a bearing element is in turn mechanically coupled to the annular cylinder, which includes a tapered bore so that an interior diameter of the annular cylinder decreases from one end to the other. An inner race of the bearing element includes accepts the annular cylinder. The interior diameter of the inner race decreases from one end to the other. A locking ring locks the annular cylinder to the bearing element. Holes extend radially through the locking ring. A screw thread mechanically couples with the bearing assembly, which screw thread is inscribed on an interior surface of the locking ring. Cutout sections in the screw thread are formed by the holes. Setscrews disposed in the holes hold the locking ring in place.

  • Publication number: 20080075402
    Abstract: A mounting system is disclosed for mounting a bearing assembly or other mechanical element to a shaft. The mounting system uses a tapered sleeve mechanism to secure the bearing assembly on the shaft. Specifically, a pressure loaded piston drives the sleeve from a pre-assembled position to an initial position. The initial position is determined by monitoring the pressure applied to the piston. Once the initial position has been reached, a linear indicator is used to measure the axial sleeve movement from the initial position to a final position. The system remains in place after the bearing is installed on the shaft and facilitates removal of the bearing assembly from the shaft.

  • Patent number: 7344313
    Abstract: A bearing assembly lockable onto a shaft. The bearing assembly comprises a first tapered adapter defining a first axial bore for the receipt of the shaft which has an outer, annular tapered surface. There is a second tapered adapter defining a second axial bore for receipt of a sleeve portion of the first adapter. The second tapered adapter has an outer, annular tapered surface tapered at a taper angle opposite to that of the first tapered adapter such that the first and second tapered adapters co-operate to define an outer annular surface having a generally V-shaped configuration that tapers from spaced greater diameter outer ends to adjacent lesser diameter inner ends. The opposed tapered surfaces have a fixed limit in their axial travel toward each other along the shaft defined by engagement of the lesser diameter inner ends. When the tapered surfaces reach the end of their travel, the bearing supported on the tapered surfaces is tightened on the shaft with the correct clearances.

  • Publication number: 20080056634
    Abstract: A mounting system is disclosed for mounting a bearing assembly or other mechanical element to a shaft. The mounting system uses a tapered sleeve mechanism to secure the bearing assembly on the shaft. Specifically, a plurality of screws point load the tapered sleeve and drive it from a pre-assembled position to an initial position. Once the initial position has been reached a plurality of fasteners then drive the sleeve from the initial position to a final position. The difference between the initial position and final position determined by the width of a removable spacer used in the mounting system. The system also incorporates a jack screw mechanism used to dismount the bearing assembly from the shaft.

  • Patent number: 7186030
    Abstract: An expandable shaft assembly including an axially extending shaft with an axial axis, an extending shaft with an axial axis, an external dimension, at least one shaft end and a bore extending generally axially from the at least one shaft end. The shaft assembly also includes a second element, as an axle cap, with an axially extending, externally threaded portion with a first thread flank, a shoulder portion extending in a generally radially outwardly direction. A radially extending end face is also provided that is axially constrained relative to the shaft, wherein the radially extending end face is one of (1) integral with the shaft, and (2) on a separate element. The bore of the shaft includes an axially extending, internally threaded portion with a second thread flank, wherein at least one of the first and second thread flanks are inclined.

  • Patent number: 7037026
    Abstract: A method for mounting an axially split sleeve provided with an axial slot on a shaft so that a tapering surface on the sleeve cooperates with a tapering bore of a machine member. A flange is axially connected to the sleeve and supports a number of spaced apart tightening devices that are to be urged against the machine member for mutually displacing the machine member and the sleeve to increase the grip between the shaft, the sleeve and the machine member. The method involves positioning the sleeve around the shaft with the annular flange positioned with its tightening devices against the machine member, tightening a first one of the tightening devices which is located at a position diametrically opposite the slot in the sleeve, and thereafter tightening further ones of the tightening devices one by one.

  • Patent number: 6939053
    Abstract: A system is provided for securing a rotating member with respect to a non-rotating member. A hollow member, such as an inner ring of a bearing assembly, includes an extension having an annular outer groove. A tapered sleeve serves to lock the hollow member about a mechanical component, such as a shaft. A nut engageable on the sleeve includes an eccentric front aperture adjacent to a concentric groove, thereby forming a lip of varying depth. The system is engaged by rotation of the nut on the sleeve in one direction, and disassembled by counterrotation of the nut such that a portion of the varying depth lip co-acts with a lip formed by the groove of the hollow member.

  • Patent number: 6893160
    Abstract: A wedge-type bearing assembly that is easily dismounted from a shaft includes an adapter sleeve, an inner ring, and a lock nut. The split cylindrical adapter sleeve wraps around a shaft, and has a radially outwardly facing surface including a tapered section. The threaded inner ring encircles the adapter sleeve, and includes a radially inwardly facing surface engaging the tapered section of the adapter sleeve. The lock nut is fixed axially relative to said the sleeve and threadably engages the inner ring, wherein rotation of the lock nut in one direction of rotation draws the inner ring over the adapter sleeve to fix the inner bearing ring relative to the shaft, and rotation of the lock nut in a second direction urges the inner ring off of the adapter sleeve to release the inner bearing ring relative to the shaft.
