摘要： Two or more vehicle components can be operatively connected with one or more fasteners configured to provide selectively variable dampening characteristics. The fastener can include a dampening unit configured to provide different dampening characteristics based on a torque applied to the fastener. In one or more arrangements, the dampening unit can provide different dampening characteristics based on an amount of compression the dampening unit is under. Target dampening characteristics between two or more components can be determined. A torque can be determined and applied to the fastener based on the target dampening characteristics. The torque can cause the dampening unit of the fastener to compress and provide the target dampening characteristics between the components.

摘要： A tensioning system for tensioning a stud is provided. The system includes an adapter ring having an external surface, an internal surface engaging the external surface of the stud or puller screw, and at least two bores defined therein. The posts have first and second ends and are disposed in the bores. The first ends are supported by a stop surface, and the second ends extend outwardly from the bores. A cylinder includes an internal surface engaged with the external surface of the adapter ring. First and second pistons are movably positioned within the cylinder with an intermediate cap disposed therebetween to define first and second hydraulic chambers. The first piston is configured for being supported by the second ends of the posts. The hydraulic chambers are hydraulically connected to one another, whereby providing a hydraulic fluid in the chambers operates to apply a tension force on the stud.

摘要： A clamping device for expanding a threaded bolt is provided with a support pipe supported against an underlay surrounding the threaded bolt. A cylindrical housing arranged in extension of the support pipe has a piston movable in longitudinal direction and connectable to a hydraulic supply. A changeable bushing is axially carried by the piston and is provided with an inner thread and a radially expanded portion. A resilient arrangement is arranged around the bushing and acts axially on the piston. A lid is secured to the housing. The other support of the resilient arrangement is provided on the lower side of the housing. The lid has a lid base member and a closure lid. The lid base member is provided with an opening closable by the closure lid. The radial extent of the opening is greater than the radial extent of the radially expanded portion of the bushing.

摘要： A hydraulic bolt tensioning device has a cylinder supported on a machine part that is to be clamped by threaded bolt and nut. An exchangeable bushing has a first end screwed onto a free threaded end of the threaded bolt that projects past the nut. A tensioning piston is seal-tightly guided in the cylinder and supported on a second end of the exchangeable bushing. A pressure medium is supplied into an annular space between cylinder and piston. A control device is provided for setting a nominal pressure of the pressure medium corresponding to a nominal pretension of the threaded bolt. A yield limit detection device detects whether a yield limit of the threaded bolt is reached during tensioning. A controller acts on a pressure relief device for pressure relief of the bolt tensioning device when reaching, or shortly after reaching, the yield limit of the threaded bolt.

摘要： Methods and apparatus for preloading a bearing are provided. These methods and apparatus include preload monitoring procedures and devices whereby a mechanic can accurately monitor and regulate the preload on a bearing or bearing assembly. Aspects of the invention may also be used to adjust the endplay on a bearing or a bearing assembly. The methods and apparatus allow the mechanic to apply and/or verify a preload on the bearing, for example, to apply and/or verify a preferred “3 thousandths” preload, as is desired in the industry. In one aspect, the preload on the bearing is transmitted through a housing having a fluid pressure that can be detected and monitored.
