Patent number: 5655416Abstract: A vibration damper assembly to absorb vibrations in a camshaft and sprocket system has a sprocket positioned around a camshaft, an inertia ring positioned around the camshaft and adjacent the sprocket, yet capable of moving independently of the sprocket, and a hub member positioned around the camshaft adjacent the inertia ring. Frictional material is interposed between the hub member and a rim portion of the inertia ring whereby the inertia ring and hub member slide with respect to one another along the frictional material to absorb vibrations from the camshaft through heat dissipation.Type: GrantFiled: July 29, 1996Date of Patent: August 12, 1997Assignee: Borg-Warner Automotive, Inc.Inventors: Philip J. Mott, Roger T. Simpson, Kevin Todd

Patent number: 5464374Abstract: A power transmission chain includes pins and inner link apertures of a size to allow pivotal movement of the inner links about the pins. The ends of the pins and the outer link apertures are shaped such that upper and lower portions of the pin ends bear against upper and lower edge portions of the apertures to prevent movement of the outer links relative to the pins. At least one side portion of each pin is spaced apart from an adjacent side edge portion of the associate aperture.Type: GrantFiled: August 3, 1994Date of Patent: November 7, 1995Assignee: Borg-Warner Automotive, Inc.Inventor: Philip J.

Patent number: 5423724Abstract: A rocker joint for a power transmission chain is formed from a single pin and an associated link aperture. The pin has a substantially flat front surface and a convex back surface, with the back surface being defined by a plurality of radii. The pin is received in the aperture of the link such that the front surface of the pin engages and rocks on the curved surface of the link aperture. The back surface of the pin is movable in the aperture of the links as the surfaces move relative to one another when the chain articulates.Type: GrantFiled: February 15, 1994Date of Patent: June 13, 1995Assignee: Borg-Warner Automotive, Inc.Inventors: Edward H.

Patent number: 5277664Abstract: A hydraulic tensioner having a plunger slidably fitted in a mounting cavity n a housing and biased in a protruding direction by a spring and fluid. A variable orifice check valve permits fluid to only flow into, and thereby protrude the plunger, but not out of the mounting cavity is disclosed. The variable orifice check valve is accomplished with a cylindrical compression spring in which the spring coils are normally mutually contacting and which has a top spring cap molded directly to an end of the spring and a bottom spring retainer molded directly to the opposite end of the spring. Such a construction reliably secures the top spring cap and bottom spring retainer to the spring. A mechanical no-return capability is provided to the plunger through an internal ratchet positioned within the mounting cavity and constructed from a cylinder having two helical openings which the plunger engages when the plunger experiences sufficient force to be pushed inwardly.Type: GrantFiled: February 4, 1993Date of Patent: January 11, 1994Assignee: Borg-Warner Automotive Transmission & Engine Components CorporationInventor: Philip J. Mott

Patent number: 5263903Abstract: A chain-belt that extends between driving and driven members such as the pulleys of a continuous variable transmission wherein the chain-belt is formed of a plurality of interleaved sets of links. The links define a passageway and a plurality of load blocks are positioned in the passageway. Several members for reducing the noise produced by such a chain-belt are disclosed whereby certain of the load blocks in the chain-belt engage the pulleys at a different location to alter and reduce the pattern of noise produced by the chain-belt. The chain-belt also has links with a particular configuration that allows the links to have a short pitch length while still maintaining strength in the links.Type: GrantFiled: February 10, 1993Date of Patent: November 23, 1993Assignee: Borg-Warner Automotive Transmission & Engine Components CorporationInventor: Philip J. Mott

Patent number: 5259820Abstract: A hydraulic tensioner having a plunger slidably fitted in a mounting cavity n a housing and biased in a protruding direction by a spring and fluid. A variable orifice check valve permits fluid to only flow into, and thereby protrude the plunger, but not out of the mounting cavity is disclosed. The variable orifice check valve is accomplished with a cylindrical compression spring in which the spring coils are normally mutually contacting, thus preventing the transfer of fluid, but which move to a non-contacting orientation upon experiencing a desired pressure. A mechanical no-return capability is provided to the plunger through an internal ratchet positioned within the mounting cavity and constructed from a cylinder having two helical openings which the plunger engages when the plunger experiences sufficient force to be pushed inwardly.Type: GrantFiled: May 19, 1992Date of Patent: November 9, 1993Assignee: Borg-Warner Automotive Transmission & Engine Components CorporationInventor: Philip J. Mott

Patent number: 5244437Abstract: A continuously variable transmission includes an improved secondary servo arrangement in order to provide the necessary clamping forces for high torque conditions. The secondary servo includes a plurality of fluid chambers in order to allow an increase in the area for application of fluid pressure. Fluid conduits between the chambers permit communication of the fluid to the chambers to regulate the clamping force of the movable sheaves of the secondary variable pulleys.Type: GrantFiled: June 26, 1991Date of Patent: September 14, 1993Assignee: Borg-Warner Automotive, Inc.Inventors: William J. Haley, Glenn E. Swanson, Philip J. Mott
