摘要： In the damper device, when the large diameter portion (51) does not apply an impact force on the flange portion (532), the elastic body (53b, 63b, 73b) is disposed in one of the housing (22) and the cylindrical portion with a gap and when the large diameter portion applies the impact force on the flange portion, the elastic body is compressed by the restricting surface and the flange portion in an axial direction to be deformed into a state that the elastic body is brought into contact with all of the housing, the restricting surface (52b, 62b), the cylindrical portion (531) and the flange portion to be filled in the gap. The impact receiving member (53a) is restricted from a movement relative to the housing by the deformed elastic body when the end portion (531 c) of the cylindrical portion (531) is advanced into the relief portion (52f, 62f, 72f) and the impact receiving member keeps a non-contact state with the housing.

摘要： A vehicle (1) is provided of which the four wheels are steerable, and which is prevented from unexpectedly moving forward or backward when switching the travel mode. The vehicle includes a steering device (10) for front right and front left wheels of the vehicle capable of steering the front right and front left wheels, respectively, in one and the other of the right and left directions, a steering device (20) for rear right and rear left wheels of the vehicle configured, simultaneously when the steering device (10) for the front right and front left wheels are actuated, to be capable of steering the rear right and rear left wheels in the other and the one of the right and left directions, respectively, and in-wheel motors (M) provided in at least one of each of the front right and front left wheels and each of the rear right and rear left wheels.

摘要： The invention relates to a ball screw drive (10) used in a steering system. The ball screw drive (10) includes a lead screw (2a) for converting an auxiliary torque produced by an electric motor (M) into an auxiliary translational force which acts on a steering rack (2b) in the steering system of a motor vehicle. One end of the lead screw (2a) and one end of the steering rack (2b) are each connected to a track rod (3, 3') via an axial link (G), and the ball screw drive (10) has a ball nut (5) mounted in a housing (GH) with a fixed bearing (4). In order to withstand strong lateral loads or lateral forces coming from the track rod or rods (3, 3') and acting in the radial direction (y) there is provided between the end of the lead screw (2a) connected to the track rod (3) and the ball screw drive (10) a plain bearing element (20) which supports the lead screw (2a) radially against the housing (GH). The support is provided by an adjustable radial clearance, and the plain bearing element is preferably in the form of a sleeve (20) which surrounds the lead screw (2a), the sleeve (20) having a conically shaped portion (22) which is conically shaped on its outer periphery in the axial direction (x) and lies against a conically formed inner wall (23) in the housing (GH).

摘要： Provided is simple construction, in a mechanical apparatus such as a rack and pinion steering gear unit, for fastening a bearing that supports thrust loads to a member of the mechanical apparatus using a tapered snap ring, such that there is high rigidity against thrust loads. With the outer ring 17 of the bearing 15 positioned with respect to the housing 11a so that the axial length L 27 between the circumferential edge of the axial one side surface 32a of the locking groove 27 and the axial one side surface 34 of the outer ring 17 is less than the maximum thickness T 28a of the tapered snap ring 28a, the tapered snap ring 28a is locked into the locking groove 27. The gap 35 is provided between the axial other side surface 31 of the tapered snap ring 28a and the axial other side surface 33 of the locking groove 33.

摘要： A rack bush for supporting a rack shaft in a rack-and-pinion steering system so that the rack shaft slides in an axial direction thereof includes a teeth side support portion and a back side support portion. Rack teeth are formed in a first area of an outer circumferential surface of the rack shaft. The teeth side support portion contacts a second area of the outer circumferential surface to support the rack shaft from a teeth side where the rack teeth are formed. The second area lies adjacent to the first area in the axial direction. The back side support portion contacts a third area of the outer circumferential surface to support the rack shaft from a back side other than the teeth side. The third area is positioned out of the first area in a circumferential direction around an axis of the rack shaft.
