Abstract
A support assembly for supporting an upright engine exhaust pipe on an exterior wall of a truck cab at a location below an outlet of the exhaust pipe. The support assembly allows limited cab motion relative to the exhaust pipe.
Claims18
A vehicle comprising:
- a chassis supporting a fuel-consuming engine within which fuel is combusted to propel the vehicle, the engine comprising one or more exhaust manifolds;
- a cab supported on the chassis;
- an engine exhaust system through which exhaust created by combustion of fuel within the engine is conveyed from the one or more exhaust manifolds to, and then through, an exhaust pipe having a length which extends vertically upward exteriorly adjacent the cab to an exhaust outlet through which exhaust exits the exhaust system;
- an exhaust pipe support assembly which supports the exhaust pipe on the cab at a location spaced vertically below the exhaust outlet, and which comprises a first bracket mounted on the exhaust pipe and a second bracket mounted on the cab;
- the exhaust pipe support assembly further comprising a frame having a length, a width, and a thickness and comprising a cavity disposed centrally of the frame's length and width and extending completely through the frame's thickness;
- the cavity being bounded lengthwise of the frame by first and second walls having symmetrically opposite bearing surfaces which face each other across the cavity and which are in registration with each other both widthwise and thicknesswise of the frame;
- the bearing surfaces, when viewed widthwise of the frame, lying on respective circular arcs having identical radii;
- the cavity being bounded widthwise of the frame by third and fourth walls having surfaces which face each other across the cavity and which are in registration with each other both lengthwise and thicknesswise of the frame;
- a rotor which is captured within the cavity with clearance to the surfaces of the first, second, third, and fourth walls bounding the cavity and which comprises symmetrically opposite side surfaces which extend widthwise of the cavity, which face away from each other, and which when viewed in a direction widthwise of the frame, comprise respective circular arcs having identical radii each confronting a respective bearing surface with clearance to the respective bearing surface to journal the rotor for turning within the cavity about an axis of turning extending widthwise of the frame;
- the rotor further comprising a central through-hole having a straight axis which intersects the axis of turning and lies in an imaginary plane that is perpendicular to the axis of turning and that bisects the cavity widthwise between the surfaces of the third and fourth sides of the frame;
- a rod which is mounted on one of the first and second brackets and passes coaxially through the through-hole in the rotor with sufficient length and clearance to guide the rotor for coaxial translation along, and coaxial turning within, the through-hole;
- and elastomeric isolators held compressed against thicknesswise opposite surfaces of the frame at lengthwise opposite ends of the frame.

A truck vehicle comprising:
- a chassis;
- a cab supported on the chassis;
- a stack presenting an outward appearance of a vertical exhaust pipe and having a lower end supported on the chassis and having a length which extends vertically upward exteriorly adjacent the cab to an upper end;
- a support assembly which supports the stack on the cab at a location spaced vertically below the upper end of the stack and comprises a first mounting on the stack and a second mounting on the cab;
- the support assembly further comprising a frame having a length, a width, and a thickness and comprising a cavity disposed centrally of the frame's length and width and extending completely through the frame's thickness;
- the cavity being bounded lengthwise of the frame by first and second walls having symmetrically opposite bearing surfaces which face each other across the cavity and which are in registration with each other both widthwise and thicknesswise of the frame;
- the bearing surfaces, when viewed widthwise of the frame, lying on respective circular arcs having identical radii;
- the cavity being bounded widthwise of the frame by third and fourth walls having surfaces which face each other across the cavity and which are in registration with each other both lengthwise and thicknesswise of the frame;
- a rotor which is captured within the cavity with clearance to the surfaces of the first, second, third, and fourth walls bounding the cavity and which comprises symmetrically opposite side surfaces which extend widthwise of the cavity, which face away from each other, and which when viewed in a direction widthwise of the frame, comprise respective circular arcs having identical radii each confronting a respective bearing surface with clearance to the respective bearing surface to journal the rotor for turning within the cavity about an axis of turning extending widthwise of the frame;
- the rotor further comprising a central through-hole having a straight axis which intersects the axis of turning and lies in an imaginary plane that is perpendicular to the axis of turning and that bisects the cavity widthwise between the surfaces of the third and fourth sides of the frame;
- one of the first and second mountings comprising a rod having length which is parallel with length of the stack and which passes coaxially through the through-hole in the rotor with sufficient length and clearance to guide the rotor for coaxial translation along, and coaxial turning on, the rod;
- and elastomeric isolators held compressed against thicknesswise opposite surfaces of the frame at lengthwise opposite ends of the frame.
