Abstract:
An apparatus for shifting the center of gravity of a vehicle having three wheels or more is provided. The apparatus includes: a movable frame having a certain shape and movably fixed, at one side, to a vehicle body in such a manner that a portion or all of the frame is movable to the left/right side relative to the driving direction of the vehicle body; and a control unit for controlling the left/right movement of the frame to shift the center of gravity of the vehicle body as needed, the control unit including: a cylindrical rotation body in which a portion of the inside thereof including the center of rotation is open; a rotation bar coaxially coupled to the center of rotation of the rotation body to rotate with the rotation body along with the rotation of the rotation body; a first link member rotatably coupled, at its one end, to the rotation bar included inside the rotation body; and second link members crossed each other, each second link member having opposite ends wherein one end is rotatably coupled to the other end of the first link member, and the other end is rotatably coupled to the upper portion of the frame, whereby the center of gravity is shifted and restored more easily, effectively, and precisely, and upon stopping, the movement of the vehicle body is precisely controlled.
Abstract:
The invention relates to an elastic elastomer joint which serves as a spring for a vehicle suspension device. The joint (1) defines an axis of rotation (Y) and comprises an inner fitting (2) and an outer fitting (4), connected by means of an elastic elastomer material. Said joint (1) is embodied for fixing by means of the outer fitting (4) to a longitudinal oscillating arm (40), connected to the axle of a vehicle wheel and, by means of the inner fitting (2), to the chassis of the vehicle and to oppose a torsional return force on subjection to a torsional load about the axis (Y). The outer fitting (4) comprises means for angular adjustment (41) of the joint about the rotation axis (Y) relative to the longitudinal oscillating arm.
Abstract:
The invention relates to an axle suspension for rigid axles of vehicles, especially air-suspended utility vehicles. The inventive axle suspension consists of a torsional four-point link (4), which is connected to the vehicle axle (3) on one side and to the vehicle body (1, 2) on the other and which is arranged above the vehicle axle (3). Said four-point link (4) is connected to the vehicle axle (3) and to the vehicle body (1, 2) by two joints (5, 6, 7, 8) which are arranged in an interspaced manner in the direction of the transversal axis of the vehicle. The axle suspension also consists of at least one suspension unit (19, 20) which is situated on each side of the vehicle between the vehicle axis (3) and the vehicle body (1, 2) in order to provide suspension, and of an axle strut (21), which extends approximately along the center of the vehicle in a longitudinal direction of the vehicle, connects the vehicle axle (3) to the vehicle body (1a, 1b) in a vertically displaceable manner, and which is provided for guiding the axle.
Abstract:
The invention relates to a guiding device for a rigid axle in a motor vehicle, comprising at least three longitudinal struts (11, 12, 42, 43), whereby two longitudinal wheel-guiding struts (11, 12) which are located on the same plane (10) and structurally coupled between coupling points (33, 34) when they guide the rigid axle by means of a multi-axle joint (31, 32). The longitudinal wheel-guiding struts are coupled between the coupling points by means of a coupling joint (35). The inventive guiding device enables powerful longitudinal and transversal forces to be transmitted to the body of the vehicle, providing good off-road mobility and a compact design.
Abstract:
A suspension system for a vehicle includes a longitudinally extending frame, an axle (44) connected to the frame for relative movement with respect thereto, an air spring (38) mounted between the frame and the axle to yieldably support the axle with respect to the frame, and upper (22) and lower (24) trailing arms attached to each side of the frame. A first torsion bar (58) extends between and is rigidly attached to the upper trailing arms and a second torsion bar (60) extends between and is rigidly attached to the lower trailing arms. The torsion bar cooperates with the springs during deflection of the suspension system with respect to the frame to thereby yieldably resist relative movement between the trailing arms and the frame. In one embodiment, the upper and lower trailing arms are parallel to each other. This arrangement results in load equalization between the suspension assemblies. Any relative torque caused by deflection of the trailing arms is equally distributed between both torque bars. In another embodiment, the upper (63) and lower (64) trailing arms are non-parallel, and arranged such that when the trailing arms pivot due to road conditions or vehicle loading, fore and aft movement of the air spring and axle due to arcuate swing of the trailing arms is minimized.
