A system and methods are provided for a suspension system of an off-road vehicle that allows the springs to be mounted remotely, in any location on the vehicle, enabling the use of spring sizes, spring rates, motion ratios, and damping profiles that would be impractical with traditional suspensions. The suspension system includes a hydraulic cylinder coupled between the wheel and the chassis, in lieu of a conventional spring. This cylinder is in fluid communication with another cylinder by way of a hydraulic hose. This second cylinder includes a piston that presses against a suspension spring that is in contact with a fixed spring stop, thus transferring spring forces to the wheel. Alternatively, the spring stop may comprise a control actuator that moves according to signals from an onboard computer control system, enabling active control over spring load and chassis attitude.

A method and system for adjusting height and damping force, the method comprising: between a first connection part (110) and a second connection part (120), arranging a pneumatic valve (130), an air spring (140), an adjustable damper (150) and a damping force adjustment device (160) used for adjusting the damping force of an adjustable damper (150), the positions of the pneumatic valve (130), the air spring (140), the adjustable damper (150) and the damping force adjustment device (160) being adaptive and the pneumatic valve (130) being connected to the damping force adjustment device (160) and the air spring (140), respectively; the pneumatic valve (130) collects at least one movement variable of the first connection part (110) relative to the second connection part (120); meanwhile, the pneumatic valve (130), according to the collected movement variable and/or the change in the movement variable, controlling the air spring (140) to inflate or deflate so as to implement height adjustment; and/or carrying out gas driving on the damping force adjustment device (160) to control the adjustable damper (150) to output corresponding damping force, so as to adjust the size of the damping force of the adjustable damper (150), which improves the sensitivity of height adjustment and damping force adjustment.

A motor vehicle has a steering axle, a drive axle and a lift axle having an actuator for lifting and lowering the same. The wheels of the drive axle can be electrically driven, at least in a supporting manner, via an electric machine operable as an electric motor and as a generator, and the wheels can be driven in a generating manner in a recuperation operation. The electric machine is connected to an accumulator and to a control and/or regulation device to control the operation of the lift axle. The device is connected to sensors for wheel slip detection at the drive axle. The device is configured such that, during a recuperation operation, it can send a command to the actuator to lift the lift axle and thereby unload the wheels thereof, if there is wheel slip at least at one wheel of the drive axle.

A soil processing machine includes a machine frame with two longitudinal beams substantially extending in the longitudinal direction of the machine and two transverse beams substantially extending transverse to the longitudinal beams. A soil-processing roller is supported in the longitudinal direction between the transverse beams on the longitudinal beams so that it can rotate about an axis of rotation of the roller. A coupling arrangement is provided on the machine frame for attaching the machine frame to a further machine frame of the soil-processing machine or to a further machine. A lifting/supporting arrangement is provided on the machine frame for lifting and/or supporting the machine frame in relation to the ground. One of the transverse beams is supported on the two longitudinal beams so that it can rotate about a swivel axis substantially parallel to an axis of rotation of the roller.

A wheel assembly of an agricultural implement includes a wheel and a wheel frame supporting the wheel. The wheel frame is configured to pivotally couple to a toolbar of the agricultural implement, and the wheel frame is configured to rotate between a lowered position and a raised position. The wheel assembly also includes a mount configured to fixedly couple to the toolbar. In addition, the wheel assembly includes a linkage assembly configured to control rotation of the wheel frame between the raised position and the lowered position. The wheel assembly also includes a fastener configured to selectively engage the mount and the linkage assembly while the wheel frame is in the lowered position to block rotation of the wheel frame.
