Abstract
The invention relates to a sub-frame, a support structure and a cab for a vehicle such as a crawler tractor. The sub-frame is mounted on the vehicle support structure by resilient mountings and a cab is mounted on the sub-frame. In this way, the cab is insulated from vibrations in the support structure.
Claims10
A cab sub-frame for a vehicle having a support structure, the sub-frame comprising first and second pairs of longitudinally and laterally spaced apart upright beam elements having upper and lower ends, a pair of lower longitudinally extending beam elements adapted to carry a floor, the lower beam elements having opposite ends connected to the lower ends of the first and second pairs of upright beam elements, a pair of upper longitudinally extending beam elements adapted to carry on operator's seat, the upper beam elements having a first end connected to the upper ends of the second pair of upright beam elements and a second end extending longitudinally therefrom, a first crossbar extending between and connected at the opposite ends thereof to the upper ends of the first pair of upright beam elements, a second crossbar parallel to the first crossbar and extending between and connected at the opposite ends thereof to the extending second ends of the upper beam elements, first and second crossbar supports longitudinally spaced and mounted to the support structure, first and second resilient mountings respectively carried by the first and second crossbars, and connecting means for connecting the first and second resilient mountings carried by the first and second crossbars respectively to the first and second crossbar supports mounted on the support structure of the vehicle, the connection insulating the mounted sub-frame from vibration in the support structure.
A tractor vehicle cab sub-frame in combination with a vehicle support frame, comprising:
- a first pair of laterally spaced upright beams;
- a second pair of laterally spaced upright beams longitudinally spaced and parallel to the first pair of upright beams;
- a first pair of longitudinally extending beams connecting the lower ends of the first and second pairs of upright beams;
- a first crossbar connecting the upper ends of the first pair of upright beams and including first resilient pad means carried thereon for providing a first dampening barrier between the first crossbar and the support frame;
- a second crossbar spaced apart parallel to the first crossbar and including second resilient pad means carried thereon for providing a second dampening barrier between the second crossbar and the support frame;
- a second pair of longitudinally extending beams extending beyond the connection of the first pair of longitudinal beams to the lower ends of the second pair of upright beams and connecting the upper ends of the second pair of upright beams to the second crossbar and forming a seat support;
- and
- sub-frame support means mounted fore and aft on the support frame for connecting the first and second resilient pad means thereto.
