A chassis for a lift device includes a base, an arm coupled to the base and configured to support a tractive element, and a plate extending from the arm at an upward angle. The arm includes a steering actuator interface configured to support an end of a steering actuator for the tractive element. The plate is configured to extend past the steering actuator.

A machine includes a chassis, a turntable coupled to the chassis, a boom coupled to the turntable, an axle, a first actuator, and a second actuator. The chassis has a first end and an opposing second end, and defines a longitudinal center axis. The turntable is selectively rotatable about a rotation axis. The axle is pivotally coupled to the first end of the chassis and configured to pivot about the longitudinal center axis. The first actuator is coupled to the first end of the chassis and positioned on a first side of the longitudinal center axis. The first actuator is extendable to selectively engage a first contact point on the axle. The second actuator is coupled to the first end of the chassis and positioned on an opposing second side of the longitudinal center axis. The second actuator is extendable to selectively engage a second contact point on the axle.

A method of on-demand energy delivery to an active suspension system comprising an actuator body, hydraulic pump, electric motor, plurality of sensors, energy storage facility, and controller is provided. The method comprises disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

An electrified vehicle, comprising a chassis having a frame, a first tractive element, and a first suspension system coupled with the first tractive element and the chassis. The first suspension system may comprise a first knuckle coupled with the first tractive element, and a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle. The first suspension system may also include a first control arm coupled with the first knuckle and the frame member, and a torsion bar coupled with the chassis at a first end of the torsion bar. The torsion bar may extend in a direction substantially parallel with the frame member, where the torsion bar may be configured to support a portion of a mass of the electrified vehicle in response to displacement of the first tractive element relative to the chassis.

Mobile apparatus comprising a main frame with displacing means; a sub-frame connected rotatably to the main frame; an operating arm connected to the sub-frame and comprising at least a first and a second articulation which are connected pivotally to each other, which operating arm can be transformed from an operating position to a transport position; drive members configured to move at least the first and second articulations of the operating arm; operating instruments controllable by a driver and provided close to a driver position on the sub-frame; measuring instruments configured to measure position data relating to a position of the first articulation and a position of the second articulation; and a control system configured to receive operational data from the operating means and position data from the measuring instruments; and configured to control the drive members in accordance with the received position data and the operational data.

A self-driving vehicle with an integrated fully-active suspension system. The fully-active suspension utilizes data from one or more sensors used for autonomous driving (e.g. vision, LIDAR, GPS) in order to anticipate road conditions in advance. The system builds a topographical map of the road surface. Suspension and road data is delivered back to the vehicle in order to change autonomous driving behavior including route planning. Energy storage is regulated based on a planned route. Forward and lateral acceleration feel is mitigated through active pitch and tilt compensation. The fully-active suspension pushes and pulls the suspension in three or more operational quadrants in order to deliver superior ride comfort, handling, and/safety of the vehicle.

A suspension system for a vehicle axle including at least one hydraulic suspension cylinder, which has at least one work space, with the work space being connected to a hydraulic accumulator and allowing a connection via switching arrangement as well as to a pressure source and a pressure release. A shut-off valve is arranged between the work space and the accumulator, by which the suspension can be blocked. In order to avoid during the unblocking process that any sudden compensating motion of the axle suspension develops, here the suspension system includes at least one detection device connected to the work space of the suspension cylinder and the accumulator, which is embodied to detect the pressure difference between the work space and the accumulator. This way a pressure difference can be reliably detected at both sides of the shut-off valve, thus between the work space of the suspension cylinder and the accumulator, and can be compensated in a targeted fashion during or before the opening of the shut-off valve for unblocking the suspension.
