| 464140000 | With additional axially spaced torque-transmitting coupling which facilitates relative movement between members | 8 |
| 20080248883 | Universal Joint - A universal joint ( | 10-09-2008 |
| 20080261707 | Joint Arrangement - A joint arrangement including a constant velocity ball joint ( | 10-23-2008 |
| 20090203454 | Bearing device for wheel - It is an object of the present invention to reduce cost of a hub wheel in a bearing device for wheel for a drive wheel or a driven wheel. | 08-13-2009 |
| 20090298597 | Power transmission line section - A power transmission section particularly adapted for use in a downhole drilling system. A drive shaft is pivotally connected to input and output end connection members with pivot balls therebetween to allow pivoting of the shaft ends relative to the input and output end connection members. A plurality of ball segments having one spherically-curved surface are provided at each end of the drive shaft to engage with the input and output connection members and to transmit torque between the shaft ends and the input and output end connection members, regardless of the angular variation between the drive shaft longitudinal axis and the longitudinal axes of the input and output end connection members. | 12-03-2009 |
| 20100081511 | LONGITUDINAL SHAFT ASSEMBLY FOR A MOTOR VEHICLE - A longitudinal shaft assembly for a motor vehicle, comprising at least a first shaft and a second shaft, a ball-type constant velocity joint for connecting the first shaft to the second shaft and at least one central bearing for supporting the longitudinal shaft assembly with respect to a body of the motor vehicle. | 04-01-2010 |
| 20100081512 | SHAFT DRIVE TYPE MOTORCYCLE - A shaft drive type motorcycle includes a drive shaft, a constant-velocity universal joint interposed in the drive shaft, and the pinion gear provided at one end of the drive shaft and meshed with a final gear. A shaft part may be extended from a cup of the constant-velocity universal joint, the shaft part is provided with male splines, and a tubular part extends from the pinion gear. The tubular part is provided with female splines in which to fit the male splines, and the male splines and the female splines are coupled with each other. | 04-01-2010 |
| 20100216557 | WHEEL BEARING DEVICE, METHOD OF ASSEMBLING WHEEL BEARING DEVICE, ASSEMBLY CONFIGURED BY WHEEL BEARING DEVICE AND DRIVE SHAFT, AND METHOD OF ASSEMBLING ASSEMBLY - The present invention provides a wheel bearing device, a method of assembling the wheel bearing device, an assembly configured by the wheel bearing device and a drive shaft, and a method of assembling the assembly, in which the wheel bearing device eliminates a nut tightening operation, is capable of reducing costs, and has a projection and recess mating structure that can firmly connect an outer joint member and a hub. | 08-26-2010 |
| 20120295719 | DRIVE WHEEL BEARING DEVICE - A drive wheel bearing device is provided with an outer member, an inner member, double-row rolling elements and a constant velocity joint. The inner member includes double-row inner races opposite outer races of the outer member, a first inner member, and a second inner member formed with at least one of the double-row inner races, the first inner member and the second inner member being inseparably coupled together at a flange-like swaged portion. The constant velocity joint includes an outer joint member press-fitted to an inner periphery of the first inner member with torque transmission means formed therebetween that transmits torque by engagement of a plurality of axially extending teeth, wherein the torque transmitting teeth of the first inner member have a tooth profile that is controlled within a specified range over the entire axial length of the teeth. | 11-22-2012 |
