A front upper suspension connection for a space frame comprises a bottom surface fixedly attachable to a front lower suspension connection; a top rear mounting surface fixedly attachable to a front upper frame connection; a top front mounting surface fixedly attachable to a first elongate support member; a front strut attachment point located below the top rear mounting surface and the top front mounting surface to pivotably attach a front strut; and a lower rear mounting surface located below the top rear mounting surface fixedly attachable to a second elongate support member. The front strut attachment point can include a hole passing through the top rear mounting surface, a coaxial hole passing through the top front mounting surface, and a front strut attachment pin configured to pass through the top rear mounting surface, the top front mounting surface, and a top mounting hole integral to the front strut.

A front lower suspension connection for a space frame comprises a U-shaped base and upper suspension control arm support sections on the U-shaped base. The U-shaped base can have a cross-beam section and suspension column support beam sections positioned at opposite ends of the cross-beam section, where each suspension column support beam section may include lower suspension control arm pivot joint supports located at opposite ends of the suspension column support beam sections. Each upper suspension control arm support section can have a first support column and a second support column spaced from the first support column, where the first support column may include a first upper suspension control arm pivot joint support, and the second support column may include a second upper suspension control arm pivot joint support and a front mounting surface. A rear mounting may be provided on a rear surface of the front lower suspension connection.

A front upper frame connection for a space frame can comprise a top surface; a bottom surface opposite the top surface; a right-side surface; a left-side surface opposite the right-side surface; a front surface; a rear surface opposite the front surface; a pair of forward support plates provided on the front surface; a pair of forward flat mounting surfaces; and a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface. The front surface and the forward support plates can define a cutout section. Each of the forward support plates is curved and runs outward from a transverse centerline of the top surface and then forward.

A machine for road work, the machine can comprise: a frame; a rotor coupled to the frame and configured for rotational movement relative thereto; a milling system actuator configured to raise and lower the rotor to selectively disengage and engage with a surface of a working area; a first position sensor configured to sense a first position of a left side of the rotor relative to the surface; a second position sensor configured to sense a second position of a right side of the rotor relative to the surface; and a controller configured to, in response to signals received from the first position sensor and the second position senor, determine at least a cross-sectional area of the rotor that is engaging the surface.

A paver includes a main vehicle body and a set of fore-wheels. The set of fore-wheels is connected to the main vehicle body via a hydraulic wheel suspension system which, in at least a paving mode of the paver, allows hydraulic level compensation for each wheel of the set of fore-wheels. The paver further includes a hydraulic motion control assembly adapted to selectively provide hydraulic spring suspension and/or hydraulic dampening to at least one wheel of the set of fore-wheels.

Systems and apparatuses include a chassis mount configured to couple to a vehicle chassis, an axle assembly including wheels, a four-bar linkage coupling the axle assembly to the chassis mount, and a hydraulic cylinder coupled between the chassis mount and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position and acts as a spring damper suspension component.

A road finisher includes an undercarriage, a chassis which is adjustable in height relative to the undercarriage, an electronic control system, and a paving screed which is attached to tie bars, the tie bars each being hinged to the chassis at a pull point and the pull points each being adjustable relative to the chassis by means of a leveling cylinder. The control system comprises a receiving unit configured to detect an actual pull point height, an evaluation unit configured to calculate a deviation of the actual pull point height from a target pull point height caused by a height adjustment of the chassis relative to the undercarriage, and a command unit, which is configured to automatically at least partially correct the deviation by a correction signal sent from the command unit causing a hydraulic controller to adjust at least one of the leveling cylinders.

The present disclosure includes independent suspension systems or members, as well as wheeled skid steer loaders or other power machines including the same, that couple each wheel to a machine frame using a four-bar linkage, with the four bars including the frame of the machine, an upper control arm, a lower control arm, and a wheel carrier link. Each control arm is pivotally attached to both the machine frame and one end of the wheel carrier link. The four pivots between the control arms and the wheel carrier link are configured to all be contained within cylinder defined by the outer diameter of the wheel rim, allowing for a compact structure with the wheel carrier link and at least part of the control arms being positioned within this volume when the loader is in a resting position.

An implement with a ground-engaging tool may include a frame supported above a surface of a ground by a ground-engaging portion and a suspension and a tool supported by and adjustable relative to the frame and configured for working the ground. The implement may also include a plurality of ground sensors configured for capturing distance measurements to determine the position of the frame relative to the surface and a control and monitor system configured for establishing a nominal scratch position of the tool relative to the surface based on the distance measurements. A method of controlling a rotor tool depth of a milling machine and a method of operating a milling machine are also described.

An implement with a ground-engaging tool may include a frame, a ground-engaging portion for supporting the frame on a surface of ground, and a suspension system coupling the ground-engaging portion to the frame and for adjusting the frame relative to the ground-engaging portion. The implement may also include a tool supported by and adjustable relative to the frame and configured for working the ground. The implement may also include a control and monitor system configured for establishing a nominal position of the tool relative to the surface and for establishing an actual position of the tool relative to the surface based on an offset adjustment. A method of determining a rotor tool depth of a milling machine and a method of operating a milling machine may also be provided.
