Embodiment Construction

[0054] figure 1 The embodiment shown in is a measuring assembly 10 for measuring forces, in particular unbalanced forces resulting from an unbalance of a rotating rotor, notably rotating a vehicle wheel (not shown). The measuring shaft 12 is rotatably mounted in a first bearing 40 for rotation about its shaft axis Z. In this example, for example, the measuring shaft 12 is rotatably supported by means of roller bearings (not shown) in the tubular first bearing 40 .

[0055] A drive 70 , in particular an electric motor, is provided for rotating the measuring shaft 12 in the first bearing 40 . The rotation of the drive mechanism 70 is transmitted to the measuring shaft 12 by means of a drive belt 72 . The drive mechanism 70 is itself supported relative to the first bearing 40 by a support member 74 rigidly connected to the first bearing 40 and the drive mechanism 70 .

[0056] Electronics 76 are then provided, for example, to drive a clamping system for clamping a vehicle whee...

Abstract

The present invention relates to a measuring unit (20) for measuring forces generated by an unbalance of a rotor mounted on a measuring shaft (12), particularly of a vehicle wheel mounted on a measuring shaft (12) of a wheel balancing machine, the measuring unit (20) comprising a stationary frame (60), a first bearing (40) for receiving the measuring shaft (12) rotatably about its shaft axis (Z), a second bearing (50) pivotally supporting the first bearing (40) about a pivot axis (Y) which intersects the shaft axis (Z) and being supported on the stationary frame (60), a first force sensor (22) for measuring forces generated by an unbalance of the rotating rotor and acting on the measuring shaft (12) about the pivot axis (Y), and a second force sensor (24) for measuring forces generated by the unbalance of the rotating rotor and acting on the measuring shaft (12) and on the second bearing (50) in a direction intersecting the shaft axis (Z), wherein the second bearing (50) and the stationary frame (60) are integrally formed of a single element as a support plate (30).

Description

technical field [0001] The invention relates to a measuring unit for measuring the forces generated by an imbalance of a rotor mounted on a measuring shaft. The invention also relates to a measuring assembly comprising the measuring unit and a wheel balancing machine. [0002] More precisely, the invention relates to a measuring unit for measuring the forces generated by the imbalance of a rotor mounted on a measuring shaft, in particular a vehicle wheel mounted on the measuring shaft of a wheel balancing machine, the measuring unit comprising: a fixed frame; a first bearing for receiving a measuring shaft rotatable about its shaft axis; a second bearing pivotally supporting the first bearing about a pivot axis intersecting the shaft axis and supported on the fixed frame a first force sensor for measuring the force generated by the unbalance of the rotating rotor and acting on the measuring shaft about the pivot axis; and a second force sensor for measuring the force generate...
