Patent number: 10576801Abstract: A transverse control arm (1) of an axle arrangement for a vehicle having two transverse control arm struts (2, 3) and at least three kinematics points (4, 5, 6). Each of the two transverse control arm struts (2, 3) has a carrier hub end (9) and a carriage end (10). At least one of the two transverse control arm struts (2, 3) has a curvature (7) in a spatial direction, and this spatial direction being along a vertical axis that extends generally perpendicular relative to the plane defined by the at least three kinematic points (4, 5, 6).Type: GrantFiled: April 25, 2016Date of Patent: March 3, 2020Assignee: ZF FRIEDRICHSHAFEN AGInventors: Alexander Neu, Knut Heidsieck, Peter Kontermann, Holger Lohmüller, Nils Mühl, Philipp Grevemeyer

Patent number: 10414224Abstract: A wheel suspension assembly (1) for a vehicle, having a spring damper (2), a first transverse link (4), which has a first transverse link strut (4a) and a second transverse link strut (4b), a second transverse link (5), a first tie rod (6), a second tie rod (7), a reversing lever (8), a hub carrier (9), a steering gear (10) and a pendulum support (11). Each transverse link (4, 5) has an end (12), on the hub carrier side, and two ends (13, 13a, 13b), on the chassis side. The steering gear (10) is arranged in a plane with the first transverse link (4) and in a section between an end (13a) of the first transverse link strut (41) of the first transverse link (4), on the chassis side, and an end (13b) of the second transverse link strut (4b) of the first transverse link (4), on the chassis side.Type: GrantFiled: April 25, 2016Date of Patent: September 17, 2019Assignee: ZF Friedrichshafen AGInventors: Alexander Neu, Knut Heidsieck, Peter Kontermann, Holger Lohmüller, Witalij Knaub, Joachim Cichy, Klaus Solik

Patent number: 7950727Abstract: A suspension arrangement for spring suspending a mass body (3) in relation to a substructure (1), for example, a driver's cabin (3) of a heavy goods vehicle in relation to the vehicle chassis (1) thereof. The suspension arrangement comprises a spring/damper arrangement (2) which is arranged between the mass body (3) and the substructure (1) and which is used to dampen thrusts and/or oscillations. The suspension arrangement in characterized in that it comprises at least one pantograph (6) which is used to reduce the freedom of movement of the mass body (3). The inventive suspension arrangement is constructively robust and can determine the provided freedom of movement of the mass body in a reliable manner and can dampen and/or prevent undesired movements in other spatial directions. The invention enables an economical and a reliable spring suspension, in particular, for a driver's cabin of heavy good vehicles, to be produced.Type: GrantFiled: June 16, 2006Date of Patent: May 31, 2011Assignee: ZF Friedrichshafen AGInventors: Felix Haeusler, Holger Lohmüller, Knut Heidsieck

Patent number: 7914024Abstract: Wheel suspension for a vehicle (7), with a carrier element (5), with a wheel carrier (1), which is arranged at a spaced location from the carrier element (5) and which is pivotable about a steering axis (30), with a wheel (14) mounted rotatably on the wheel carrier (1), with a steering wheel (58), which is mounted rotatably on the carrier element (5) at least indirectly and by means of which the wheel carrier (1) is pivotable about the steering axis (30), with at least one joint (8), which is connected to the wheel carrier (1) and which has a housing (26), a pivot pin (25) mounted pivotably in same and an angle-measuring device with a magnet (27) and with a magnetic field-sensitive sensor assembly unit (28), and with at least one guide means (2), via which the joint (8) is connected to the carrier element (5).Type: GrantFiled: June 16, 2006Date of Patent: March 29, 2011Assignee: ZF Friedrichshafen AGInventors: Holger Lohmüller, Felix Haeusler, Michael Klank, Joachim Spratte

Patent number: 7695054Abstract: A suspension device is provided for the spring-loaded suspension of a weight body (3) relative to a substructure (1) such as a vehicle body, a cab (3) of a truck relative to the vehicle chassis (1). The suspension device has a spring/absorber device (2) arranged between the weight body (3) and the substructure (1) for absorbing shocks and vibrations. The suspension device includes at least one Watt's linkage arrangement (6) connecting the weight body and the substructure for reducing the degrees of freedom of motion of the weight body (3). The suspension device requires little maintenance and has little clearance and is suitable for setting the degrees of freedom of motion of the weight body as well as for absorbing and preventing the undesired motions of the weight body along other directions in space. The suspension device thus makes possible an inexpensive and reliably operating suspension especially of truck cabs.Type: GrantFiled: September 13, 2006Date of Patent: April 13, 2010Assignee: ZF Friedrichshafen AGInventors: Felix Haeusler, Jens Eismann, Timo Kuepker, Holger Lohmueller, Marc von Lienen
