A suspension system comprises a leaf spring and a slider box. The leaf spring is a cambered leaf spring and comprises a first end with a first coupler that couples to a first point on a frame of a vehicle and a second end. Further, a pivot point resides between the first end and the second end. The slider box comprises a coupler that fixedly couples the slider box to a second point on the frame of a vehicle. Further, an opening of the slider box accepts the second end of the leaf spring such that the leaf spring slides in the slider box when the leaf spring is flattened. Moreover, the spring box comprises a foreshortening mechanism that changes an effective length of a portion of the leaf spring between the second end of the leaf spring and the pivot point of the leaf spring as the leaf spring flattens.

The invention relates to an axle suspension on a vehicle frame, comprising: an axle bracket which in its longitudinal direction is arranged transversely to the vehicle frame and at its longitudinal ends each is provided with a wheel carrier, a pendulum support which is connected with the axle bracket via a swivel bearing and is accommodated in a self-aligning bearing attached to the vehicle frame, wherein the swivel bearing has a swivel axis which extends parallel to the longitudinal axis of the vehicle frame.

A shock absorber according to the present invention is configured to include: a shock absorber main body in which an outer tube and a rod axially movably inserted into the outer tube are included; a suspension spring formed of a coil spring disposed on the outer periphery of the shock absorber main body; a rod-side spring seat attached to the rod and supporting one end of the suspension spring; an annular tube-side spring seat screwed to a screw portion provided on the outer periphery of the outer tube and supporting the other end of the suspension spring; a slider to be placed on the outer periphery of the outer tube with only an axial movement is permitted; a connecting portion that detachably connects the tube-side spring seat to the slider; and a rotation regulating portion that regulates a rotation of the tube-side spring seat and the slider relative to each other about the axis of the outer tube in a state where the tube-side spring seat and the slider are connected to each other.

The present disclosure provides a suspension system, and a chassis with the same. The system includes: a fixing frame having an opening; a suspension frame disposed at the opening; and a driving wheel rotationally coupled to the suspension frame. In which, two ends of the suspension frame are respectively disposed on two ends of the fixing frame at the two sides of the opening to be selectively moved up and down along a height direction of the fixing frame, and two elastic members are respectively disposed between each of the two ends of the suspension frame and the corresponding end of the fixing frame at the two sides of the opening. In the present disclosure, the fixing frame and the suspension frame can move with respect to each other in a vertical direction, and the resetting adjustment is realized through the elastic member.

A motor vehicle wheel suspension, comprising a guide wheel having an outer jacket comprising a wheel attachment for the connection of the guide wheel to a rotation pin of a wheel. The guide wheel extends between opposite axial upper and lower ends in correspondence of which it comprises attachments for its connection to connection elements of an associated frame, wherein said outer jacket internally encloses a damper and a spring. The outer jacket, in correspondence of one of said axial upper and lower ends comprises a slot for realizing a first attachment to connection elements of the frame, said slot housing a pin axially guided by said slot, the slot connecting a cavity inside the outer jacket with said pin. The outer jacket, in correspondence of the other of said axial upper and lower ends comprises a tilting hinge for realizing a second attachment to connection elements of the frame.

A steering device for a vehicle, having an actuator which is designed to apply an axial force to a push rod. The push rod is connected to a respective steering rod on both sides in an articulated manner, and each steering rod is connected to a respective steering arm in an articulated manner. Each steering arm is operatively connected to a respective wheel carrier in order to rotate a respective wheel of a vehicle axle about a respective steering axis according to an axial movement of the push rod and has at least one first and a second arm section. The two arm sections of each steering arm can be moved towards each other in an axial direction in order to change a transmission ratio of the steering device when the wheels are being steered and to reduce the axial force on the actuator.

A wheel suspension system is disclosed. The wheel suspension system may include a suspension assembly that may include a sub-frame adapted to be connected to a reference frame of a vehicle, a wheel interface adapted to rotatably support a wheel of the vehicle and to define a wheel rotation axis and a wheel rotation plane, and one or more linking units. Components of the linking unit(s) may be pivotally connected to each other, to sub-frame and to the wheel interface using pivoting connection that may cause components of the linking unit(s) to rotate about axes that are substantially perpendicular to the wheel rotation axis. The components of the linking unit(s) may be dimensioned, and positions of the pivoting connections may be set to cause a substantially linear motion of the wheel interface along a reference wheel interface motion axis that is perpendicular to the wheel rotation axis.

A slider suspension system for a heavy-duty vehicle includes a slider assembly with a main member that is movable relative to a primary frame of the heavy-duty vehicle in a first direction along the extent of the main member. The main member has a first portion and a second portion extending transverse to the first portion. A friction reducing slider wear pad is fixed to the main member and interposed between the main member and the primary frame. The friction reducing slider wear pad has a first segment fixed to the first portion of the main member. The friction reducing slider wear pad also has a second segment engaging at least a part of the second portion of the main member to inhibit movement of the friction reducing pad relative to the main member in a second direction transverse to the first direction.

A chassis system for commercial vehicles includes a trailing arm and a plunger piston which are connected or can be connected to one another via a connecting region, the connecting region having an adjusting device which includes an engagement element and a guide element, and it being possible for the engagement element to be moved relative to the guide element in such a way that a displacement, in particular a translational movement, of the plunger piston relative to the trailing arm is made possible.
