A fluid-filled tubular vibration-damping device including: an inner shaft member and an outer tube member connected elastically; a non-compressible fluid filling region formed between the members; and a partition wall rubber partitioning the filling region into fluid chambers at axially-opposite sides thereof connected by an orifice passage, wherein the partition wall rubber protrudes into the filling region on one of inner shaft member side and outer tube member side, while a concave groove opens to the filling region extending in a peripheral direction on an other of the sides, and a tip part of the partition wall rubber is inserted in the concave groove without being compressed in an axis-perpendicular direction and is configured to be axially pressed against an inner face of the concave groove to constitute a sealer fluid-tightly obstructing a space between the partition wall rubber and the inner face.

A tractor includes a cabin composed of a plurality of frames; a vehicle body installed at an lower portion of the cabin and composed of a guide bar, an engine and a transmission to supply power; links connecting the cabin and the transmission at a front portion; first and second front elastic cylinders installed at one side of the links; and first and second rear elastic cylinders connecting the cabin and the transmission at a rear portion.

A suspension system for a work vehicle includes a rear suspension assembly that includes a first shock absorber assembly and a second shock absorber assembly, such that each of the first and second shock absorber assemblies has a first end that couples to a cab of the work vehicle and a second end that couples to a chassis of the work vehicle. The rear suspension assembly further includes a brace extending laterally between the first end of the first shock absorber assembly and the first end of the second shock absorber assembly relative to a direction of travel of the work vehicle, such that the first end of the first shock absorber assembly and the first end of the second shock absorber assembly are coupled to the brace. In addition, the rear suspension assembly includes a longitudinal tie rod oriented substantially longitudinally along the direction of travel of the work vehicle, such that the longitudinal tie rod has a first end rotatably coupled to the brace and a second end configured to rotatably couple to the chassis of the work vehicle. The first end of the first shock absorber assembly and the first end of the second shock absorber assembly decouple from the cab without decoupling the brace from the first end of the first shock absorber assembly and the first end of the second shock absorber assembly.

A tilting system for a suspended cab of a work vehicle includes a hydraulic cylinder coupled to a chassis of the work vehicle at a first end and the suspended cab at a second end. Further, the hydraulic cylinder is configured to extend to drive the suspended cab to rotate from a lowered position to a raised position. In addition, the hydraulic cylinder is configured to be substantially horizontal while the suspended cab is in the lowered position.

The present invention relates to a bearing arrangement for a driver's cab (12) of a vehicle, which bearing arrangement is, in a mounted state, arranged between the driver's cab (12) and a cab support (16) of the vehicle, having a cone bearing (14) which, centrally, has a bearing sleeve (34) which is fixable to the driver's cab (12) and which extends through an opening (38) of the cab support (16) and which is of hollow form, wherein the bearing sleeve (34) is, at the outside, by way of an elastic damping element (22) connected thereto, connected to a concentrically arranged support element (24), wherein the support element (24) is fixable to the cab support (16) at the cab side by way of connecting elements (26), and having an abutment element (30) which is arranged on an end, averted from the driver's cab (12), of the bearing sleeve (34) and which serves for limiting a movement of the damping element (22) in an axial direction (A). The bearing arrangement is characterized in that an installation element (30) is arranged on a side, facing toward the abutment element (30), of the cab support (16), which installation element is, by way of the connecting elements (26), fastened to the cab support (16) concentrically with respect to the bearing sleeve (34).

Disclosed herein is an engine compartment soundproof cover device of a cab-over truck. The engine compartment soundproof cover device includes a soundproof cover, side covers, and a plurality of expandable connectors. The soundproof cover is installed below a cab in which a driver is seated and is configured to cover an upper portion of an engine compartment. The side covers are installed on chassis frames of both sides of the engine compartment and configured to come into contact with a lower end of the soundproof cover to seal both sides of the engine compartment. The plurality of expandable connecters is configured to connect the soundproof cover to a lower portion of the cab and capable of expanding toward the side covers to allow the lower end of the soundproof cover to be pressed against the side covers.

A hydraulic excavator includes a revolving frame forming a support structure, a cab that is disposed to be positioned on a front side of the revolving frame and in which an operator gets, and a plurality of vibration isolating members that are disposed between the revolving frame and the cab to support the cab on the revolving frame in a vibration isolating state. Further, an intermediate connecting member is disposed for connection between the revolving frame and the vibration isolating member and for a height position adjustment of the cab to the revolving frame. The intermediate connecting member is fixed to the revolving frame from a lower side.

A commercial motor vehicle having a chassis, an engine compartment defined between parallel elongate beams of the chassis, and a driver cabin positioned at least partially over the engine compartment. The driver cabin being supported on the chassis by spaced resilient suspension devices, and includes an upper cabin part and a lower cabin part. The upper cabin part is tiltable to allow access to the engine compartment by being hinged about a lower edge, while the lower cabin part remains associated with the chassis when the upper cabin part is tilted. The lower part of the driver cabin is supported by the resilient suspension devices.
