摘要： The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.

摘要： A two track tractor with an active suspension system for reducing pitch jerk and a method of operation thereof utilizes a position sensor between a nose of the tractor and a front axle assembly connected to a forward rolling element. The gap between the nose and the front axle is continually measured and an average gap value is produced. An active suspension system is controlled by a microprocessor to vary the pitch angle between the tractor body and the axle assembly in order to maintain a target nose gap while limiting the pitch jerk experienced by the operator.

摘要： A device for damping vibrations acting on a tracked vehicle is provided, which has a front and rear track roller. Torsion springs are mounted along a vehicle pan. Alternatively, the torsion springs can be subdivided into smaller torsion springs. For the immediate track rollers, a further device is provided in which the long torsion springs which hitherto absorbed the torsion are divided into a plurality of smaller torsion springs and mounted not transversely with respect to the vehicle pan, but in a direction of travel with respect thereto. The torsion springs are functionally connected to one another via drive and/or transmission elements, and are accommodated outside an interior space. In this way, no further installation space is required transversely with respect to and below the vehicle pan, at most in the side region or within a small recess in the pan, a so-called pan niche.

摘要： A suspension system for cold planer with four tracks is disclosed. The suspension system includes a hydraulic cylinder for each track, an additional bypass valve for each hydraulic cylinder and an additional bypass valve that bypasses the operation of the front control valves that control the elevation of the front tracks during a cutting operation. During transport or roading of the cold planer, the bypass valves are energized by a controller and the energized bypass valves provide communication between the head ends of the left side cylinders and the head ends of the right side cylinders. During roading, the energized bypass valves also provide communication between the rod ends of the front cylinders and between the rod ends of the rear cylinders.

摘要： An in-arm suspension (12) is provided for actively controlling a suspension arm (20) mounted to a vehicle frame (14). The suspension arm (20) has a housing (60) in which the a compressible fluid strut (32) and a fluid control section (90) are enclosed. The compressible fluid strut (32) includes a cylinder (134) and a piston rod (136) which is urged to extend from within the cylinder (134) in response to fluid pressure applied to compressible fluid disposed within the cylinder (134). A damper piston (174) is mounted to an interior portion of the piston rod (136), and moves with the piston rod (136) to pass the compressible fluid through the damper piston 174 and attenuate bounce and rebound of the piston rod (136) within the cylinder (134). A damper lock (210) is mounted to the piston rod (136) for selectively preventing the flow of compressible fluid through the damper piston (174).
