Patent number: 8604437Abstract: A method for measuring and testing a vehicle frame (15), in particular a commercial vehicle or bus frame, wherein a radiation source and a radiation receiver are arranged in front of the frame (15) and radiation is beamed from the radiation source toward the frame (15) and onto a reflector support (1) having at least one reflector (2, 3, 4, 5). The reflector (2, 3, 4, 5) is assigned to a part of the frame (15), and the radiation is reflected by the reflector (2, 3, 4, 5) to the radiation receiver and a measuring device determines location coordinates of the reflector (2, 3, 4, 5) at different measuring points of the frame part. A substantially non-deformed section (A) of the frame part is ascertained from the resulting measuring points (P) and the variation of the measuring points (P) from the non-deformed section (A) is determined.Type: GrantFiled: September 21, 2011Date of Patent: December 10, 2013Assignee: Haweka AGInventors: Dirk Warkotsch, Alexander Eberle, Tilo Janz, Harald Schenitzki

Patent number: 7941933Abstract: A clamping device for mounting a vehicle wheel on a balancing machine. The clamping device has a clamping flange and a plurality of centering bolts. The clamping flange is provided with plural sets of recesses for the centering bolts. An insertable section of each centering bolt is removably insertable into a recess. A profiled contour in the insertable section of the centering bolt and an inner contour of a sidewall of the clamping flange delimiting the recess are not circular and have complementary shapes such that the centering bolt is accommodated in the recess such that some sections of the centering bolt can be rotated about the longitudinal axis thereof. When the centering bolt is rotated, at least one subarea of a circumferential surface in the insertable section of the centering bolt frictionally engages with at least one adjacent subarea of the sidewall of the clamping flange delimiting the recess.Type: GrantFiled: March 3, 2008Date of Patent: May 17, 2011Assignee: Haweka AGInventor: Dirk Warkotsch

Publication number: 20100170340Abstract: A clamping flange that is designed to press a rim of a vehicle wheel against a flange of a shaft of a balancing machine and has a clamping plate with a plurality of recesses for accommodating centering bolts and a central opening to be slid onto the shaft of the balancing machine. The centering bolts can be inserted into the front of the clamping plate. The clamping flange is slidable onto the shaft while a clamping arrangement is provided for centering the clamping flange on the shaft. The clamping arrangement encompasses a clamping sleeve which is mounted in the central opening so as to be movable in an axial direction relative to the clamping plate. The clamping sleeve is movble into a clamping position by applying a pressure acting in an axial direction. In the clamping position, the clamping sleeve is mounted without play on the shaft and clamping flange.Type: ApplicationFiled: March 3, 2008Publication date: July 8, 2010Applicant: HAWEKA AGInventor: Dirk Warkotsch

Patent number: 6688173Abstract: The invention relates to a balancing device consisting of a balancing machine provided with a shaft for clamping a wheel, a supporting frame and a cover which is placed on top of the supporting flame. The balancing machine can be pivoted 90° in relation to the supporting frame, moving from a horizontal measuring position to an upper position or centering position. In order to facilitate handling when the wheel is placed on the shaft of the balancing machine, said balancing machine is provided with a height adjustment device which enables the balancing machine to be lowered into the supporting frame and moved out of the centering position, whereby the outer end of the shaft does not protrude above the cover.Type: GrantFiled: December 14, 2001Date of Patent: February 10, 2004Assignee: Horst WarkotschInventor: Dirk Warkotsch

Publication number: 20020015632Abstract: A speed clamping nut to clamp the rim of a vehicle wheel on an end fitted with an outer thread of a shaft of a balancing machine, comprising a housing having at least one grip mounted in substantially radially manner to the housing, and an inside thread. A threaded component rotational about the screw axis of the speed clamping nut and relative to the housing is connected to the housing and comprises an inside thread and is connected with the drive side of a rotational drive system connected to the housing. Following engagement, the rotational drive system assumes the complex and time-consuming screwing-on procedure when the wheel rim is pulled against spring forces toward a centering cone.Type: ApplicationFiled: September 17, 2001Publication date: February 7, 2002Inventors: Dirk Warkotsch, Herald Oppermann, Guy W.

Patent number: 6282799Abstract: Device for affixing the wheel-alignment sensor is mounted on a main body at a given reference direction to it. Three support arms are mounted on the main body and run substantially radially in a plane which is perpendicular to the reference direction. Spacers are mounted on the support arms in transversely displaceable manner thereto. The spacer ends that will constitute a three-point support on a wheel rim are situated in a plane which is perpendicular to the reference direction. Element(s) to affix the main body to the wheel rim are provided. At least one of the spacers (24, 54) is adjustable transversely to its mounting arm. In this manner the position of the spacers can be matched to different pitches of wheel affixing nuts.Type: GrantFiled: July 14, 2000Date of Patent: September 4, 2001Assignee: Haweka Auswuchttechnik Horst Warkotsch GmbHInventor: Dirk Warkotsch
