Abstract: Due to the meshing of the gears, the following force works on the rack. A separating force (Fα) determined by a pressure angle of gears, a lateral force (Fβ) determined by an angle of torsion of the rack, and drag (Fr) for offsetting angular moment occurring in the rack due to the lateral force (Fβ). A resultant (F) of the force works from the rack on the rack guide. When the line of this resultant (F) is held on the “inner side” of the end portions of the needle bearing 25 in this rolling type rack guide 21, the rotation of the roller 22 becomes stable.

Abstract: An electric power steering device having a speed reduction gear using a toothed belt and capable of preventing the speed reduction gear from being locked and steering from being disabled even if the toothed belt is broken. A clearance Δ between the inner surface (21x) of the second housing (21b) of the speed reduction gear (40) and the rear surface (29a) of the toothed belt (29) applied to a toothed pulley (27) is formed larger than the tooth depth (H) of the toothed belt (29) (Δ>II). Thus, even if the toothed belt (29) is broken, the toothed belt (29) is not caught between the inner surface (21x) of the second housing (21b) and the outer peripheral surface (27a) of the second toothed pulley (27), and the toothed pulley (29) is not locked.

Abstract: Under a state of a normal temperature, a pitch B2 of a feed nut 55, 65 is formed to be slightly larger than a pitch A2 of a feed shaft screw 53, 63. Accordingly, since the screw thread of the feed nut 55, 65 is pressed to the screw thread of the feed screw shaft 53, 63 with a small interference, there is no backlash between the feed screw shaft 53, 63 and the feed nut 55, 65 so that a smooth feeding operation can be carried out. Under a state of a low temperature, the feed nut 55, 65 contracts more than the feed screw shaft 53, 63. As a result, a pitch B1 of the feed nut 55, 65 has the substantially same dimension as that of a pitch A1 of the feed screw shaft 53, 63.

Abstract translation: 在正常温度的状态下，进给螺母55,65的间距B2形成为稍大于进给轴螺杆53,63的间距A2。因此，由于进给螺母55,65的螺纹 被挤压到进给丝杠轴53,63的螺纹，干涉小，进给螺杆轴53,63和进给螺母55,65之间没有间隙，从而可以进行平稳的进给操作。 在低温状态下，进给螺母55,65比进给螺杆轴53,63收缩更多。因此，进给螺母55,65的间距B1具有与间距A1相同的尺寸 的供给螺杆轴53,63。

Abstract: A variable steering gear mechanism (9) is constructed of an external gear (15) connected to an input shaft (11), an internal gear (16) fixed to housing (10) and meshing with the external gear (15), an intermediate member (19) receiving a rotary force transmitted from the external gear (15), change means (18a, 31, 33a) capable of changing a rotation ratio of the output shaft (33) to a rotation of a guide member (18), and an Oldham coupling (17) connecting the intermediate member (19) to the guide member (18). When a speed reduction ratio thereof is set to, e.g., 6:1, it follows that the input member (18) of the change means makes a ¼ rotation (rotates through 90 degrees) during one-sided 1.5 rotations (540 degrees) of the input shaft (11), whereby a characteristic of the change means can be effectively utilized. A gear mechanism such as a hypocycloid mechanism has a characteristic capable of, though compact in configuration, obtaining a speed reduction ratio as large as 6:1, and also such a characteristic that the external gear (15), in addition to the self-rotation, revolves around the axis line of the internal gear (16), i.e., rotates while being eccentric. By contrast, according to the present invention, the use of the Oldham coupling (17) enables only the self-rotation to be extracted and transmitted by absorbing the eccentricity of the external gear (15). Additionally, a meshing length between the external gear (15) and the internal gear (16) becomes large, whereby smoother power transmission can be attained.

Abstract: To provide an electrically driven power steering apparatus with a simple structure, which can prevent overloading of an electrical motor and a power transmission system, an absorbing member (121) is attached to a rack shaft (112), and is brought into contact with a rack housing face at a stroke end of the rack shaft (112). The absorbing member (121) at least partially has a material having a Young's modulus of 100 to 900 Mpa, and thus it is possible to effectively relieve an impact at the stroke end.

Abstract: The torque sensor of the present invention converts the torsion of a shaft into an amount of movement of a slider member and detects the amount of movement of the slider member as a variation in the self-inductance of a detection coil unit. The detection coil unit is a bobbin having a coil wound thereon. The bobbin has a cylindrical portion, first and second annular flange portions provided on axially opposite ends of the cylindrical portion, and a third annular flange portion provided between the first and second flange portions. The coil is wound on a second groove defined between the second and third flange portions. An end portion of the coil is connected and fixed to a lead wire (connected to a detection circuit unit) in a first groove defined between the first and third flange portions. The diameter of one of the flange portions of the detection coil unit can he larger than the diameter of the other flange portions to prevent improper assembly of the detection coil unit.
