摘要： A hub shaft of a hub wheel for the mounting of a wheel thereon and an outer ring of a constant velocity joint are connected together. A first side surface spline is formed on an end surface of the hub shaft, and a second side surface spline is formed on an end surface of a side wall portion of the outer ring abutting against the end surface of the hub shaft, and the first and second side surface splines are meshed with each other to connect the hub shaft of the hub wheel and the outer ring of the constant velocity joint together in a torque-transmitting manner, each of the two side surface splines having a number of spline teeth. At least one of the spline teeth of at least one of the two side surface splines is removed to form a removal portion which forms a drain passage.

摘要： In a wheel bearing assembly, an outer surface of a head portion of a link bolt contacts an inner surface of an end wall portion of a constant-velocity joint outer ring. A shaft portion of a link bolt is press-fit into a penetration hole of the constant-velocity joint outer ring. An external threaded portion of the link bolt is inserted into the central hole of a hub spindle so that the external threaded portion protrudes from an outer end surface of a hub wheel. A lock nut is fastened to the external threaded portion, so that the wheel hub and the constant-velocity joint outer ring are linked, and the first spline and the second spline are meshed so as to be capable of torque transmission.

摘要： In a ball screw device, a ball screw nut is rotated, causing a screw shaft to rectilinearly move in the axial direction, and the limit of the movement of the screw shaft is determined by a stopper. The ball screw device includes a hollow shaft that rotates together with the ball screw nut and in which the screw shaft is movably fitted. The hollow shaft is provided with a small diameter portion that exerts a dragging force on the screw shaft before the screw shaft reaches the limit, and a buffer layer is formed on a tip portion of the screw shaft.

摘要： A wheel bearing apparatus includes a roller bearing, an inner shaft having an outer circumferential surface to which an inner ring of the roller bearing is installed, a coupler ring attached to an end portion of the inner shaft, and a caulked portion provided in an end portion of the inner shaft so as to fix the coupler ring and the roller bearing to the inner shaft so as to be immovable in an axial direction of the inner shaft. An outer diameter of the coupler ring is set smaller than a diameter of a shoulder portion of the inner ring. Alternatively, a protruding portion is provided in any one of opposing end surfaces of the coupler ring and the inner ring, whereby the coupler ring is arranged away from a seal member. Accordingly, it is possible to avoid an interference of the coupler ring with the seal member.

摘要： Power of an engine is divided to be transmitted to a power transmission path to front wheels and a power transmission path to rear wheels by a transfer mechanism where the power has just passed through a transmission so as to be transmitted to front wheels and rear wheels. In addition, a torque reduction and transmission joint is provided on the power transmission path to the rear wheels, so that the rotational drive torque to the rear wheels is reduced to be transmitted thereto. Additionally, constant velocity joints which are provided on the power transmission path to the rear wheels are configured to have a smaller torque transmission capacity and a smaller size than those of constant velocity joints which are provided on the power transmission path to the front wheels.
