A wheel balancer incorporates tire bead manipulating tools under control of a processing system to apply a clamping pressure to tire sidewall surfaces of a wheel assembly secured to a spindle shaft, facilitating the proper seating of tire beads to the wheel rim. The spindle shaft is operatively coupled to a drive motor and transmission system under control of the processing system, capable of operating in both a high speed, low torque regime and a low speed, high torque regime to rotate the wheel assembly during either an imbalance measurement procedure or a tire bead adjustment procedure. A load roller assembly, under control of the processing system, is disposed to selectively apply a radial force at a tire circumferential tread surface as the wheel assembly is rotated about the spindle axis, further facilitating the proper seating of the tire beads.

A holding device for a rim of a vehicle wheel, comprising a base plate, a plurality of retaining elements, a synchronization element, and a locking element for locking a rotational position of at least one of the plurality of retaining elements or the synchronization element. The plurality of retaining elements and the synchronization element comprise corresponding coupling portions for form-fitting coupling of the rotational movement of the plurality of retaining elements and the synchronization element. Any one of the synchronization element or at least one of the plurality of retaining elements comprises an elastic coupling portion, biasing the corresponding coupling portions of the synchronization element and the retaining elements towards each other for ensuring the form-fitting coupling of the synchronization element and the plurality of retaining elements.

An unbalance detection device for detecting unbalance of a rotor of a turbo-cartridge which includes the rotor including a turbine wheel and a compressor wheel coupled via a rotational shaft and a bearing housing accommodating a bearing which supports the rotor rotatably, includes: a turbine-side housing member accommodating the turbine wheel; a compressor-side housing member accommodating the compressor wheel; a support mechanism configured to nip and support the turbo-cartridge from both sides by pressing at least one of the turbine-side housing member or the compressor-side housing member toward the turbo-cartridge; a vibration insulator interposed in each of a gap between the turbine-side housing member and the turbo-cartridge and a gap between the compressor-side housing member and the turbo-cartridge; and a vibration sensor installed so as to be contactable with the bearing housing, the vibration sensor being capable of detecting vibration upon rotation of the rotor.

A balancing device for turbochargers comprises a base body having a centrally disposed receiver. A rotation element to be balanced can be axially inserted to hold the rotation element in the receiver such as to turn about its axis of rotation. A number of hydraulic cylinders are arranged around the central receiver on the base body for fixing a core assembly of the turbocharger in the central receiver. The base body is in the form of a decoupling plate having an inner plate section and a stationarily positioned outer plate section elastically connected to the inner plate section and surrounding the inner plate section. The decoupling plate has a number of peripheral slots resiliently decoupling the inner plate section from the outer plate section such that a number of separate holding sections are formed on the de-coupling plate.
