摘要： A rotor assembly comprises a rotor having annular flange including a plurality of protrusions axisymmetrically disposed about the annular flange, each protrusion having a mounting aperture for selectively receiving a balancing feature, and a plurality of slots axisymmetrically disposed about the circumference of the annular flange between adjacent protrusions. Each slot has a pair of converging flat portions extending axially inwardly from an adjacent protrusion end, an inner flat portion at an inner end of each slot, and a pair of curved portions respectively joining each converging flat portion to the inner flat portion in each slot. Each slot has a depth at least as great as an adjacent mounting aperture depth extending normally from the adjacent protrusion end to a far end of the corresponding mounting aperture.

摘要： A tire load estimation system includes at least one tire supporting a vehicle, in which the at least one tire includes a pair of sidewalls extending to a circumferential tread. A sensor is mounted to the at least one tire. A footprint is formed by the tread and includes a centerline with a footprint centerline length. The footprint centerline length is measured by the sensor. A tire load estimator receives a precalibrated sensitivity, the footprint centerline length during straight-line driving conditions, a reference footprint value, and a reference load value as inputs. The tire load estimator determines an estimation of tire load and outputs the estimation to at least one of a vehicle control system and a vehicle electronic control unit. A method for estimating the load of a tire is also provided.

摘要： An apparatus includes a receiving module, a conversion module, first and second rollers, a motor, and a cutting head. The receiving module receives a desired weight value. The conversion module converts the desired weight value to a first length of wheel weight material based on a linear density of the wheel weight material. The first and second rollers engage first and second opposing sides of a continuous strip of the wheel weight material. The linear density of the wheel weight material is approximately constant along the continuous strip. The motor directly drives the first roller based on the first length. The cutting head is selectively actuated to cut the wheel weight material.

摘要： A method is described for calibrating a balancing machine, in which a rotor (1) to be corrected is rotatably mounted in bearings (2) and a correction run k is performed, wherein at least one measuring sensor (3) determines an initial vibration of the rotor (1) prior to an imbalance correction and transmits this vibration to an evaluation device (4), which stores the measured value as vibration vector {right arrow over (s)}0. After an imbalance on the rotor (1) is corrected, a residual vibration of the rotor (1) is measured by measuring sensor (3), transmitted to the evaluation unit (4) and stored as vibration vector {right arrow over (s)}1. The difference δ{right arrow over (s)}={right arrow over (s)}1-{right arrow over (s)}0 formed from the measurement data and the corrected imbalance is stored for compensation run k as δ{right arrow over (s)}k and {right arrow over (u)}k by the evaluation unit (4). To undertake a calibration of the machine, one can either determine a process calibration matrix K by solving the equation system S=UKT using the collected measurement data or one can select an already available process calibration matrix using the initial vibration {right arrow over (s)}0 and/or imbalance vector {right arrow over (u)} and store it as a calibration matrix in the evaluation unit (4) and use it to calculate an unknown imbalance vector of a rotor (1).

摘要： In a method for cleaning a fastening surface (2) for a balancing element on an inner face (3) of a rim (4) of a vehicle wheel (5), the vehicle wheel (5) is positioned in a holding apparatus (13) such that a cleaning apparatus (9) can be moved, by means of a handling apparatus (6), to the fastening surface (2) on the inner face of the rim (4) of the positioned vehicle wheel (5). The cleaning apparatus (9) is arranged at a free end of the handling apparatus (6). The cleaning apparatus (9) is then moved by the handling apparatus (6) to a wetting device (15) filled with a cleaning agent (11) and is wetted with cleaning agent (11) in the wetting device (15). The cleaning apparatus (9) wetted with cleaning agent (11) is then moved by the handling apparatus (6) into the wheel rim (4), where it is moved such that the cleaning apparatus (9) cleans at least one fastening surface (2) on the inner face (3) of the wheel rim (4).
