Abstract: A delashing assembly includes a tightening device for tightening a nut in relation to a main shaft supported on bearings and a wireless interface, wherein torque information is received by the tightening device over the wireless interface. A main shaft and main nut assembly, as well as a steering system, may include the delashing assembly. A method of delashing the main shaft and main nut assembly includes providing a tightening device on a first end of the main shaft and sending torque information from a second end of the main shaft to the tightening device over the wireless interface.

Abstract: A motor mounting assembly (30) for attaching a motor (32) to a housing (34) is presented. The mounting assembly (30) includes a pair of flanges (36, 38), one on the housing (34) and one on the motor (32). Each flange (36, 38) has a recess (54, 66) extending around its circumference. A hollow cover (44) is inserted over the flanges (36, 38) and crimped into the recesses (54, 66) to fasten the cover (44) and the motor (32) to the housing (34). The cover (44) includes inner and outer shells (84, 86) separated by a viscoelastic adhesive (88). A resilient damper (40) is sandwiched between the housing flange (38) and the motor flange (36).

Abstract: A method and apparatus for improving the return-to-center motion of a steering wheel (16) wherein a determination of a first and a second value; secondly, derive a set of two values from the first value; thirdly, compute a third value from the set of two values and the first value according to a predetermined formula; and fourth, calculate a steering command using the third value and the second value for enhancing the return-to-center motion.

Abstract: An exemplary embodiment of the invention is a method for controlling application of return torque in a vehicle power steering system. The method includes detecting a current hand wheel center and comparing the current hand wheel center to a previous hand wheel center. A change in hand wheel center is detected in response to the comparison. Application of return torque is controlled in response to detecting a change in hand wheel center.
