Patent number: 11267308Abstract: Independent wheel suspensions for a motor vehicle are described herein. An example independent wheel suspension includes a link to be pivotably coupled to a vehicle body of the motor vehicle via a first flexible pivot bearing and a second flexible pivot bearing. The first and second flexible pivot bearings form a pivoting axis. The link has a wheel attachment point to which a vehicle wheel is to be coupled. The example independent wheel suspension also includes a spring to be disposed between the link and the vehicle body. The spring is configured to produce a force component on the link that is directed outward along a transverse axis of the motor vehicle and that increases during compression.Type: GrantFiled: November 22, 2019Date of Patent: March 8, 2022Assignee: Ford Global Technologies, LLCInventors: Andreas Carlitz, Thomas Schmitz

Patent number: 9421844Abstract: The present disclosure provides a torsion beam axle for a vehicle. The torsion beam axle comprises two longitudinal swing arms connected by a torsion profile and two bearing arrangements. Each bearing arrangement is configured to attach a respective longitudinal swing arm to a body of the vehicle. Each bearing arrangement has a rotational axis, and the rotational axes of the bearing arrangements run in parallel to or are aligned with one another. Each of the bearing arrangements has a bearing core, which is connected to one of the longitudinal swing arms, and at least one bearing arm which is coupled to the bearing core. The bearing arm comprises a supporting section, which is coupled to the bearing core, and an elastic bending section with a connecting region, via which the bearing arm can be at least indirectly attached to the body of the vehicle.Type: GrantFiled: September 18, 2014Date of Patent: August 23, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Andreas Carlitz, Eric Leonard Branger, Gunter Wuersig, Thomas Schmitz

Publication number: 20110248465Abstract: The invention relates to a rear wheel suspension, which has a spring, preferably embodied as a coil spring that has a geometric spring center line and a line of action of force, the coil spring being supported in an upper and a lower spring mount. In order to reduce the forces imposed on structural elements of the rear wheel suspension, the proposal is that the spring be embodied and arranged in such a way that the line of action of force thereof has an amount of tilt during an inward deflection which is different from an amount of tilt during an outward deflection.Type: ApplicationFiled: April 11, 2011Publication date: October 13, 2011Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Andreas Carlitz, Theo Kueppers, Jens Glorer

Patent number: 7706947Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive and operating drives for the movement of the load-lifting device (1). A calculation model (D) is stored in a control device (SE), to which directly or indirectly acting sensors (S) are connected for detecting the lifting load (L), the lifting height (H), the tilting angle (WM), the load torque (M), the direction of travel (R), the driving speed (V), and the steering angle (WL). The control device (SE) is designed to determine a driving and load state (Z) based on the detected physical variables (L, H, WM, M, R, V, WL) and the stored calculation model (D) and is operatively connected to the traction drive and the operating drives. Depending on the driving and load state (Z) determined, the operating speed, starting and braking acceleration, and driving speed are each reduced.Type: GrantFiled: April 6, 2005Date of Patent: April 27, 2010Assignee: Linde Material Handling GmbHInventors: Gerhard Bozem, Andreas Carlitz, Bernhard Götz, Jürgen Roth, Frank Schröder

Patent number: 7392978Abstract: A wheel suspension comprising a vehicle body, a wheel movably articulated on the vehicle body via a control arm assembly. A wheel carrier and at least one helical pressure spring which is supported on the vehicle body on the one hand and on the wheel carrier or the control arm assembly on the other hand. The spring stiffness of the vehicle body support referred to the wheel contact point of the wheel can be controlled so as to be variable. Use is made of a helical pressure spring assembly whose force action line deviates from the geometric spring center line. Furthermore, there are provided rotational means for the 3-dimensional adjustment of the force action line relative to the geometric spring center line.Type: GrantFiled: December 6, 2005Date of Patent: July 1, 2008Assignee: Muhr und Bender KGInventors: Andreas Carlitz, Jörg Neubrand, Rolf Hengstenberg

Patent number: 7165643Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive, operating drives, and a steering drive. A calculation model (D) based on vehicle-specific information is stored in a control device (SE). A plurality of sensors (S) detect physical variables (V, R, H, M, L, WM, WL, BL, BQ, G) relevant to the tipping behavior of the industrial truck. The control device (SE) determines a driving and load state (Z) based on the detected physical variables (V, R, H, M, L, WM, WL, BL, BQ, G) and the stored calculation model (D) and is operatively connected to the traction drive, the operating drives, and the steering drive such that, depending on the driving and load state (Z) determined, corrective interventions (K1, K2) which maintain or increase the tipping stability can be carried out.Type: GrantFiled: April 6, 2005Date of Patent: January 23, 2007Assignee: Linde AktiengesellchaftInventors: Gerhard Bozem, Andreas Carlitz, Bernhard Götz, Jürgen Roth, Frank Schröder
