Operator's cab in a construction vehicle having a body of the operator's cab which is mounted on a chassis frame of the vehicle by the interposition of air spring devices provided between the bottom of the operator's cab body and the chassis frame and connecting mechanism for connecting through resilient members the operator's cab body with the chassis frame. The connecting mechanism comprises first and second coupler levers connected longitudinally and transversely, respectively, between the bottom of the operator's cab body and the chassis frame to restrict and absorb longitudinal and transverse oscillations of the operator's cab body, and/or a third coupler lever connected longitudinally between the top of the operator's cab body and an upstanding gate-shaped frame fixedly mounted on the chassis frame.

A final drive assembly for a vehicle comprising a housing, an input pinion gear rotatably supported by the housing, a sun gear shaft rotatably supported by the housing, a final drive bull gear fixedly secured to the sun gear shaft and in mesh with the input pinion gear, a planetary reduction gear group with a carrier thereof being rotatably mounted on the sun gear shaft, a sprocket rotatably mounted on the housing, and a torque tube fixedly secured to the sprocket and mounted for rotation on the sun gear shaft, the torque tube being coupled with the carrier.

Final drive assembly for vehicles

A scavenging gear pump for use in a final drive comprising a drive gear and a driven gear, each being mounted for rotation and in mesh with each other. The drive gear is coupled with an input shaft and rotated thereby and has formed therein a fluid passage for communicating an outlet port of the pump with a fluid chamber formed in the input shaft. A plurality of guide passages are formed in the input shaft for supplying lubricant from the fluid chamber to rotary components, such as bearings and gears.
