An active roll control apparatus is provided. To adjust a stiffness value of the stabilizer bar by moving a stabilizer bar installed between left and right wheels of a vehicle and extending in a first direction and a stabilizer link connected to the stabilizer bar, the active roll control apparatus includes a sliding part having one side connected to the stabilizer bar and the other side connected to the stabilizer link to slide the stabilizer link in a second direction perpendicular to the first direction, and a movement restricting part installed at the sliding part to restrict movement when the sliding part slides.

A clutch apparatus for a stabilizer may include: an inner race fixed to a first transmission bar, with a first guide recess part formed in a longitudinal direction in an outer surface of the first transmission bar; a housing fixed to a second transmission bar and installed in a shape enclosing the outer surface of the inner race, with a second guide recess part formed in the housing at a position facing the first guide recess part; a ball disposed between the inner race and the housing and having opposite sides respectively inserted into and retained in the first guide recess part and the second guide recess part; and a driver disposed inside the housing and configured to move the ball along the first guide recess part and the second groove and control power transmission between the inner race and the housing.

A robot according to an embodiment of the present disclosure may comprise: a base; a driving wheel protruding downward from the base; a plate spaced upward from the base; a through hole formed at the plate; a suspension bar including a shaft part rotatably connected to the base and vertically extending upward, and a screw part vertically extending from an upper end of the shaft part toward the through hole; a slider sliding along the shaft part and connected to the driving wheel; a bushing top configured to move up and down along the screw part when the suspension bar rotates; a spring located on an outer circumference of the suspension bar and located between the bushing top and the slider; and a motor disposed above the plate and connected to the screw part through the through hole to rotate the suspension bar.

The present disclosure relates to a check rail for a rail suspension in a vehicle. The check rail may include a check rail body, and a ball-and-socket joint pan formed in the check rail body, wherein the ball-and-socket joint pan may include a circumferential inner wall and a receiving opening, with a ball-and-socket joint pin with an articulated ball in the ball-and-socket joint pan, and with a plastic injection layer configured to embed the articulated ball in the ball-and-socket joint pan between the circumferential inner wall of the ball-and-socket joint pan and the articulated ball.

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 suspension module includes a spindle pivotably connected to an axle with a pivot element defining a vertical axis. The spindle has an attachment member and an attachment cap, with outer ends are rigidly interconnected by a pair of lift cylinders. The spindle includes a plate extending between the lift cylinders intermediate the attachment member and cap with the pivot element received between the attachment member and plate. Each lift cylinder has a ram movable within a housing of the lift cylinder. A wheelbox mounts to the wheel and couples with the spindle. First and second strut rods connect the wheelbox with the ram of one of the lift cylinders, and third and fourth strut rods connect the wheelbox with the ram of a second lift cylinder. The strut rods allow the spindle to move relative to the wheelbox while also transferring pivot torque between the wheelbox and the spindle.

A wheel suspension for a vehicle axle, in particular a front axle, of a two-track vehicle includes a wheel carrier configured to support a vehicle wheel, and a link assembly configured to articulate the wheel carrier to a vehicle body. The link assembly includes at least one two-point link articulated on a side of the wheel carrier to the wheel carrier at a first mounting point and on a side of the vehicle body to the vehicle body at a second mounting point. The two-point link executes a pivotal movement in the event of a head-on collision to enable a collision-proximal vehicle wheel to move backwards. The two-point link includes a stop member to limit the pivotal movement in the event of the head-on collision, by impacting a body-side counterpiece, thereby forming a body-side third mounting point to block and counteract the pivotal movement of the two-point link.

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.

The invention relates to an arrangement in a forestry machine (100), in which arrangement there is a chassis (12), a single-axle set of wheels (13) pivoted to the chassis (12), and at least one auxiliary wheel (18) fitted the outside the set of wheels (13), in order to increase the load-bearing capacity of the rear part (19) of the chassis (12). The arrangement further includes at least one support arm (20) arranged to carry the said auxiliary wheel (18) at its first end (22) and pivoted at its second end (24) to the said chassis (12) with the aid of a transverse shaft (23), a support surface (36) attached to the chassis (12) and a counter surface (38) attached to the said support arm (20), for limiting the transverse movement of the support arm (20). The invention also relates to a corresponding forestry machine.
