Patent number: 9587688Abstract: A brake rotor retaining tool includes a main body having a first end, a second end with a bore extending from the first end and a grip portion. The bore has a non-threaded surface portion and a threaded surface portion. The non-threaded surface portion of the bore extends from the first end of the main body between the first end of the main body to the threaded surface portion. The non-threaded surface portion also has a first overall length measured in an axial direction of the bore. The threaded surface portion of the bore extends from the non-threaded surface portion toward the second end of the main body and has a second overall length measured in the axial direction of the bore. The first overall length is greater than the second overall length.Type: GrantFiled: February 19, 2014Date of Patent: March 7, 2017Assignee: Nissan North America, Inc.Inventors: David Zdeb, Scott Warnecke, Lakshmi Vaidyanathan

Patent number: 9233581Abstract: A display and a controller are used to implement a tire pressure optimization system for a vehicle. The controller is programmed to receive inflation pressure information indicative of a vehicle tire's inflation pressure, and identify an operating state of the vehicle as being in an optimum state when the inflation pressure information indicates optimum performance, in a warning state when the inflation pressure information indicates the inflation pressure is beyond a warning pressure threshold, or in an advisory state when the inflation pressure information indicates an undesirable performance characteristic outside of the warning state and the optimum state. The controller is programmed to operate the display to output an optimum state indication when the operating state is in the optimum state, a warning indication when the operating state is in the warning state, and an advisory indication when the operating state is in the advisory state.Type: GrantFiled: December 5, 2013Date of Patent: January 12, 2016Assignee: NISSAN NORTH AMERICA, INC.Inventors: Scott Fritz, Farokh Kavarana, David Zdeb, John DeYoung

Patent number: 9056532Abstract: A pressure detection device and a controller in communication with the device are used to implement a tire pressure optimization system for a vehicle. The pressure detection device detects a vehicle tire's inflation pressure. The controller is programmed to identify the vehicle as being in a warning state when the inflation pressure is below a warning low pressure threshold, identify the vehicle as being in an optimum state when the inflation pressure is within an optimum pressure range where the vehicle will exhibit optimum performance, and identify the vehicle as being in an advisory state when the inflation pressure is within an advisory pressure range where the vehicle will exhibit an undesirable performance characteristic. The advisory pressure range is outside of the optimum pressure range and above the warning low pressure threshold.Type: GrantFiled: December 5, 2013Date of Patent: June 16, 2015Assignee: Nissan North America, Inc.Inventors: Farokh Kavarana, Scott Fritz, David Zdeb, John DeYoung

Publication number: 20060219506Abstract: A shock absorber includes a hydraulic fluid-filled cylinder, a piston moveably disposed within the cylinder, a piston rod attached to the piston for movement therewith, a piston rod seal sealingly engaging the piston rod and adapted to inhibit leakage of hydraulic fluid from the cylinder, and a friction member engaging the piston rod to provide friction damping. In an embodiment, the friction member includes a flexible membrane that contacts the piston rod and a biasing member adapted to apply a radially inwardly directed biasing force against the flexible membrane such that a given level of friction is developed. A method for providing friction damping in a shock absorber is also disclosed.Type: ApplicationFiled: March 31, 2005Publication date: October 5, 2006Inventor: David Zdeb

Publication number: 20060219505Abstract: A shock absorber includes a hydraulic fluid filled cylinder having a cylinder wall and a piston moveably disposed within the cylinder and separating the cylinder into first and second chambers. The piston includes a duct that extends through the piston to provide communication between the first chamber and the second chamber so that hydraulic fluid is free to pass through the piston as the piston moves within the cylinder, at least one piston ring, and a deflectable valve member that cooperates with the duct to regulate fluid flow between the first and second chambers as the piston moves within the cylinder. A friction member is positioned between the piston and the cylinder wall. The friction member is adapted to provide, among other things, a select amount of frictional damping.Type: ApplicationFiled: March 31, 2005Publication date: October 5, 2006Inventor: David Zdeb

Publication number: 20060222280Abstract: A shaft assembly is provided that has a shaft having a groove disposed in an outer surface of the shaft, a bearing disposed about a portion of the shaft, and a spacer. The spacer has at least a first side and a second side and is positioned at least partially in the groove. The first side and the second side are angled with respect to each other, such that a radially inward portion of the spacer has a narrower width than a radially outward portion of the spacer. At least a portion of the first side of the spacer engages a portion of the groove and at least a portion of the second side of the spacer exerts a longitudinal force towards the bearing.Type: ApplicationFiled: March 31, 2005Publication date: October 5, 2006Inventors: Hirotake Harada, David Zdeb
