Abstract
A method and apparatus for noise reduction in a semi-truck tractor. The semi-truck tractor has hood cowling that is carried on an upper hood support mounted to a firewall of the semi-truck tractor. The invention includes applying a resilient sleeve to the upper hood support to eliminate a noise generated by vibration of the hood cowling when supported by the upper hood support. The resilient sleeve has an opening at a proximal end of the sleeve. The sleeve is dimensioned to surround an exposed face of the upper hood support when mounted to the firewall. The resilient sleeve provides a low friction barrier between the hood cowling and the upper hood support with the hood cowling in a closed position and supported by the upper hood support.
Claims20
A noise reduction apparatus for a semi-truck tractor, the semi-truck tractor having a hood cowling for selectively accessing and closing over an engine compartment of the semi-truck tractor, an upper hood support mounted within the engine compartment of the semi-truck tractor, the hood cowling supported by the upper hood support when the hood cowling is moved to a closed position over the engine compartment, the noise reduction apparatus comprising:
- a resilient fabric sleeve having a first opening at a proximal end of the resilient fabric sleeve, the resilient fabric sleeve dimensioned to surround an exposed face of the upper hood support, the resilient fabric sleeve providing a low friction barrier between the hood cowling and the upper hood support with the hood cowling in the closed position and supported by the upper hood support.
A noise reduction apparatus for a semi-truck tractor, the semi-truck tractor having a hood cowling for selectively accessing and closing over an engine compartment of the semi-truck tractor, an upper hood support mounted within the engine compartment of the semi-truck tractor, the hood cowling supported by the upper hood support when the hood cowling is moved to a closed position over the engine compartment, the noise reduction apparatus comprising:
- a low-friction resilient fabric material configured to be removably coupled with the upper hood support and dimensioned to surround an exposed face of the upper hood support, the low-friction resilient fabric material providing a low-friction barrier between the hood cowling and a hood supporting surface of the upper hood support with the hood cowling in the closed position.
A method of noise reduction for a semi-truck tractor, the semi-truck tractor having a hood cowling for selectively accessing and closing over an engine compartment of the semi-truck tractor, an upper hood support mounted within the engine compartment and disposed to support the hood cowling when the hood cowling is moved to a closed position over the engine compartment, the method comprising:
- forming a resilient fabric sleeve having a proximal end and a distal end, the resilient fabric sleeve having an opening at the proximal end dimensioned to surround the upper hood support, the resilient fabric sleeve having a sidewall dimensioned to elastically retain the resilient fabric sleeve around the upper hood support;
- and
- applying the resilient fabric sleeve to the upper hood support, such that the sidewall is interposed between the upper hood support and the hood cowling providing a low friction barrier between the hood cowling and the upper hood support with the hood cowling in the closed position and supported by the upper hood support.
