Patent number: 7281424Abstract: The outer race 2 is fixed to the support hole 29 in the knuckle 1, and the constant velocity joint 6 is connected to the hub 3. The first seal ring 9 is fitted into the outer race 2 to cover the opening on the end of the bearing space 26. The seal ring 28 is fitted into the support hole 29 to cover the opening on the end of the detection space 27. The encoder 7 is fitted onto the inner race 4, and the outer peripheral edge of the encoder 7 faces the inner peripheral surface on the outer race 2 in an adjacent arrangement relationship to form a labyrinth clearance 36, so that grease within the bearing space 26 is prevented from leaking toward the detection space 27, whereby the rotation resistance is small to improve parts of the automobile in acceleration and fuel consumption.Type: GrantFiled: October 11, 2002Date of Patent: October 16, 2007Assignee: NSK Ltd.Inventor: Junshi Sakamoto

Patent number: 7143647Abstract: An analyzer unit for the measuring signal of a micromechanical sensor having an input/output characteristic which is represented as a characteristic curve includes means for analog-digital conversion of the measuring signal and transmission means for transmission of the converted measuring signal or a signal that depends on the converted measuring signal. The transmission means is designed so that the characteristic curve has at least two ranges having different slopes. Different resolutions of the measuring signal are implemented through the different slopes of the characteristic curve. A suitably resolved signal is thus made available for applications having different sensitivity requirements.Type: GrantFiled: August 10, 2004Date of Patent: December 5, 2006Assignee: Robert Bosch GmbHInventors: Markus Sonnemann, Christoph Gahn, Uwe Rauscher

Patent number: 7093505Abstract: A speed sensor (B, C) produces a signal that reflects the angular velocity of a shaft (4) which rotates in a case (2) having a mounting surface (10), beyond which the shaft projects to provide a target (6), and threaded holes (12) which open out of the mounting surface. The speed sensor includes a housing (20) and a sensing element (22) which is embedded in the housing. The housing, which is formed from a deformable material, has slots (44, 60) which align with the threaded holes in the case, and receive screws (24, 66) which thread into the holes to secure the speed sensor to the case. The speed sensor is positioned such that the proper air gap exists between its sensing element and the target. The screws, which extend through the slots, produce indentations (56, 74) in the deformable material of the housing, and these indentations receive the screws, so that the position of the sensor is fixed. Thus, the sensor, if removed, may be reinstalled in the same location.Type: GrantFiled: July 16, 2003Date of Patent: August 22, 2006Assignee: The Timken CompanyInventors: Wayne V. Denny, Richard Smith, Kevin Rehfus
