On one side of a worm wheel (46) in an axial direction, first thinned portions (46e) recessed toward the other side of the worm wheel (46) in the axial direction are arranged. Further, on the one side of the worm wheel (46) in the axial direction, reinforcing portions (46h) reinforcing areas between the first thinned portions (46e) and tooth portions (45) of the worm wheel (46) are arranged. Therefore, it is possible to reduce a weight of the worm wheel (46) and to suppress occurrence of distortion of the tooth portions (45) by the first thinned portions (46e). In addition, it is possible to sufficiently increase the strength of the worm wheel (46) in the vicinity of the tooth portions (45) by the reinforcing portions (46h).

The invention relates to a movement mechanism, which is provided with a base element and a support element, which, inserted into each other, form a ball hinge construction, the support element being rotatable relative to the base element about at least a first virtual axis, which passes substantially through a virtual center of the ball hinge construction. The support element is provided with drive means to enable the support element to be moved relative to the base element, which drive means comprise a first electric motor and a first drive train with an output gearwheel. The drive means are housed in the support element in order to move along with the support element when the support element is moved relative to the base element. The output gearwheel of the first drive train engages a non-straight, that is, curved, first drive rod located in the support element, this first drive rod being provided with an anchor part which is connected with the base element so that the first drive rod does not move along with the support element when the latter is moved relative to the base element.

The invention relates to an actuator mechanism for adjusting at least one angular position of a mirror element in an exterior mirror device for a motor vehicle. The actuator mechanism comprises a base element and a mirror element movably coupled with the base element, which comprises a mirror support for supporting a mirror surface. The mirror element is rotatable relative to the base element about at least a first pivoting axis with the aid of a first electric motor provided in the actuator mechanism, which extends in a longitudinal direction that is substantially transverse to a supporting surface of the mirror support. What can be elegantly facilitated by this, for instance also in the case of a relatively small mirror surface that is only a few centimeters wide and/or is only a few centimeters long, is that, as seen from a direction in which during use the mirror surface is being viewed by a driver, such electric motor does not protrude, or hardly protrudes, next to, above and/or below the mirror surface.

Disclosed herein is a reducer for an electronic power steering apparatus, which includes a gear housing including a worm shaft housing and a worm wheel housing, the gear housing being made of a heat conductive material, a worm wheel shaft connected to a steering shaft to rotate along with rotation of the steering shaft, a worm wheel accommodated in the worm wheel housing, and having a first surface and a second surface facing the first surface, the worm wheel shaft being coupled to the worm wheel, a first heat transfer plate provided to come into contact with the first surface of the worm wheel, and a first bearing coupled to the worm wheel shaft to come into contact with the first heat transfer plate, and having an outer peripheral surface coming into contact with the worm wheel housing.

A housing extends in an axial direction of a rack shaft connected to a pinion shaft so as to cover at least the rack shaft, and has an end portion on which a cover member is fitted to cover the end portion. The housing includes a holding portion that has an inner side sinking in a radial direction of the housing, and holds the cover member, and a plurality of convex portions that protrude in the radial direction of the housing, and are circumferentially disposed on a downstream side of the holding portion in a fit-in direction of the cover member, while separating from the holding portion by a predetermined distance in the fit-in direction.

A gearbox includes a first divided body and a second divided body, and a shaft projection is formed on and a through-hole is formed in divided surfaces of the first divided body and the second divided body. A second recess on the second divided body side includes a second arc portion formed concentrically with an axis center of a worm wheel, and an upper linear portion and a lower linear portion which extend linearly toward the first divided body side from both ends of the second arc portion. A first recess on the first divided body side includes a first linear portion which extends linearly in a direction orthogonal to an intersecting direction, and an upper arc portion and a lower arc portion which are formed continuous to both ends of the first linear portion.

A transmission system includes planetary gearing with a ring gear, a plurality of planet gears, a carrier, and a sun gear, a forward clutch operatively connected between the ring gear and carrier, a reverse brake operatively connected between the carrier and a rotationally fixed location, and a control subsystem to switch the transmission system between forward and reverse operational modes in the which the ring gear and the sun gear rotate in the same or opposite rotational directions, respectively. A control subsystem actuation stroke can actuate both the forward clutch and the reverse brake based on a common control signal.

A monitoring system is disclosed for identifying an operating state of a motor, the system comprising: a speed sensor for determining a speed of a motor and providing a speed signal as a function of time in response thereto, and a processor configured to identify a symmetric and/or an asymmetric oscillation of the speed signal as a function of time.

An engine, an engine starter and its housing assembly are provided. The housing assembly includes a gear mounting portion for mounting a driving gear and a switch mounting portion for mounting a solenoid switch. The switch mounting portion comprises a connecting portion and a cover body. The connecting portion is connected with the gear mounting portion and comprises a through structure for mounting the solenoid switch, the cover body covers a top end of the through structure. A wall of the connecting portion corresponding to the gear mounting portion defines an opening for mounting a shifting fork, which is in communication with the through structure.

The invention relates to a gearbox (40) having a park lock (42) which is integrated in a gearbox housing (60) of the gearbox (40). Said park lock comprises a transfer device (48), a detent (50), and a park lock gear (52). Outside the gearbox housing (60) there is an electromechanical actuator (44), which is centred on an interface to the transfer device (48) on the gearbox housing (48) and is sealed off from the gearbox housing (60) there.
