Patent number: 5445402Abstract: A vehicle wheel suspension comprises a wheel carrier which supports the wheel and which is connected in the lower area via a transverse link and a pressure strut with the vehicle body. In an articulated manner, a short A-arm is applied to the upper area of the wheel carrier and can be swivelled on a telescopic damper by means of its inner end about a swivelling axis extending approximately in the longitudinal direction of the vehicle. The telescopic damper is surrounded by a coaxial bearing spring constructed as a coil spring and is supported, like the bearing spring, in the upper area of the vehicle body. In order to compensate the bending moments exercised from the wheel load via the upper short A-arm upon the damper, the damper is connected with the transverse link so that it can be swivelled about an axis of rotation which is displaced toward the vehicle center relative to the center axis of the damper.Type: GrantFiled: September 12, 1994Date of Patent: August 29, 1995Assignee: Bayerische Motoren Werke AGInventor: Wolfgang Matschinsky

Patent number: 4828279Abstract: A wheel suspension includes a wheel carrier (2) supporting the wheel, which is rotatably connected in its lower area by way of the bearings (10, 11) with a bending- and torsion-resistant lower cross guide member (3) about the pivot axis (8). Two upper essentially transversely extending support guide members (12, 13) engage in the upper area of the wheel carrier which, like the cross guide member, are pivotally connected with their inner ends at the vehicle body. The point of intersection (P) of the axis of rotation (7) on the side of the body of the cross guide member with the extension of the pivot axis (8) lies in front of the wheel as viewed in plan view. The wheel side bearing (11) of the cross guide member is constructed elastic approximately in the plane of the cross guide member and relatively stiff perpendicularly thereto.Type: GrantFiled: March 23, 1988Date of Patent: May 9, 1989Assignee: Bayerische Motoren Werke AGInventor: Wolfgang Matschinsky

Patent number: 4671532Abstract: A rear wheel suspension for motor vehicles, especially for driven rear wheels which comprises a wheel carrier supporting the wheel, which is connected with the vehicle body by way of an upper cross guide member and two lower cross guide members. Additionally, a longitudinal arm is pivotally connected with the wheel carrier. This longitudinal arm is supported at the forward lower cross guide member between the two ends thereof by way of a connecting bearing which couples this guide member with the longitudinal arm approximately in the vertical direction but permits approximately horizontal relative movements between the guide member and the longitudinal arm. An instantaneous longitudinal center of rotation can be realized by this type of construction about which the wheel pivots during the spring compression movement whereas the real point of pivotal connection of the longitudinal arm is located considerably lower and nearer the wheel.Type: GrantFiled: February 25, 1986Date of Patent: June 9, 1987Assignee: Bayerische Motoren Werke AGInventors: Wolfgang Matschinsky, Wolfgang Sautter, Ludwig Strasser, Rudolf Mueller

Patent number: 4664412Abstract: A wheel suspension for steerable wheels, especially front wheels of motor vehicles, with a wheel carrier supporting the wheel; an upper cross guide member and a tie rod displaceable in its longitudinal direction are pivotally connected at this wheel carrier. The lower cross guide member supporting the vehicle support spring is connected by way of a corner-rigid pivot joint with an intermediate member, at which in turn the wheel carrier is supported by way of a corner-rigid pivot bearing having approximately vertical axis and a possibility of displacement in the direction of this axis. The wheel carrier and the intermediate member are each pivotally connected with an approximately vertical tension rod. The tension rod is extended beyond its pivotal connection with the intermediate member.Type: GrantFiled: February 12, 1986Date of Patent: May 12, 1987Assignee: Bayerische Motoren Werke AGInventor: Wolfgang Matschinsky

Patent number: 4591184Abstract: A wheel suspension for steerable front wheels of motor vehicles which includes a wheel carrier supporting thereon the wheel and a steering tie-rod engaging at the wheel carrier. The wheel carrier is pivotally connected with an upper cross guide member and a lower cross guide member which are each pivotally connected at the vehicle body or the like. The lower cross guide member cooperating with the support spring is supported at the vehicle body or the like by means of two pivot bearings disposed one behind the other in the vehicle longitudinal direction and is constructed torsion-resistant. The lower cross guide member is additionally connected at the other end by way of a corner-rigid pivot bearing having an essentially longitudinally extending pivot axis, with a coupling member, while the wheel carrier, in turn, is supported at the coupling member by way of an also corner-rigid pivot bearing having a vertical pivot axis.Type: GrantFiled: August 30, 1984Date of Patent: May 27, 1986Assignee: Bayerische Motoren Werke AGInventor: Wolfgang Matschinsky

Patent number: 4589677Abstract: A suspension for a rigid axle of vehicles which includes an axle body extending transversely to the driving direction, at the two ends of which is supported one wheel each. The axle body is connected with the vehicle body by way of two lateral longitudinal arms and is connected and guided with respect to the vehicle body by way of a lateral guide arrangement. The longitudinal arms are constructed bending- and torsion-rigid and are pivotally connected at the vehicle body in a rubber-elastic pivot bearings having a wide bearing base and pivot axis arranged substantially transversely and horizontally. The longitudinal arms are also connected to the torsion-rigid axle body by way of rubber-elastic pivot bearings having a wide bearing base, whose pivot axes extend, as viewed in plan view, at an inclination and intersect with the pivot axes of the longitudinal arms on the side of the body in a point at least approximately in the vehicle center plane.Type: GrantFiled: September 17, 1984Date of Patent: May 20, 1986Assignee: Bayerische Motoren Werke A.G.Inventor: Wolfgang Matschinsky

Patent number: 4556238Abstract: A three-guide member wheel suspension in which the wheel carrier is connected with the vehicle body or the like by way of three guide members pivotally connected at the vehicle body. The three guide members consist of a longitudinal guide arm, an upper cross guide member and a lower cross guide member. In order to be able to realize an effective center of rotation for the wheel carrier which lies clearly above the wheel axle in order to obtain with a rear axle a good accelerating pitching compensation and a good deceleration pitching compensation, the longitudinal arm is pivotally connected with the wheel carrier. Additionally, the upper cross guide member is pivotally connected intermediate its joint on the wheel carrier side and its joint on the body side with one end of a support strut which pivotally engages with its other end at the longitudinal arm between the pivot axis at the wheel carrier and the forward bearing support of the wheel carrier.Type: GrantFiled: August 29, 1984Date of Patent: December 3, 1985Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Wolfgang Matschinsky

Patent number: 4440419Abstract: An individual wheel suspension for a non-steered wheel of a motor vehicle such as an automobile exhibiting a change in camber of the wheel during spring deflection comprises a trailing arm which is connected to the support for the wheel and articulated to the vehicle body by means of a lengthwise arm disposed in a lengthwise direction of the vehicle and in a direction running transversely to the vehicle by means of two wishbones located one above the other. The wishbones form auxiliary tie rods in a transverse plane running vertically through the center of the wheel, the extensions of the tie rods, running toward the center of the vehicle, intersecting at a transverse pole located at a distance from the wheel center plane.Type: GrantFiled: November 16, 1981Date of Patent: April 3, 1984Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Werner Kosak, Wolfgang Matschinsky
