    摘要： A railcar adapter for connecting a railcar body to a bearing is provided. The railcar adapter includes an adapter body having two lateral channels each delimited by a pair of opposed lugs adapted to cooperate with the railcar body, an inner surface acting as a bearing seat for the bearing and an outer surface in radial contact with the railcar body. The inner surface includes at least one central groove located on a first axis of symmetry of the railcar adapter emerging in each lateral channel. The inner surface further provides a second central groove located on a second symmetry axis of the railcar adapter, perpendicular to the first symmetry axis.

    摘要： A railcar axle box includes an axle box main body accommodating a bearing supporting an axle. The axle box main body includes: an inner surface defining an accommodating space accommodating the bearing; a first side surface provided at an outer side of the inner surface and at one car width direction side of a car width direction center of the accommodating space; and a second side surface provided at an outer side of the inner surface and at the other car width direction side of the center. A shortest distance between the first side surface and the car width direction center of the accommodating space and a shortest distance between the second side surface and the center are equal to each other in a car width direction.

    摘要： A bogie for rail vehicles with a bogie frame which by means of pairs of helical springs rests on wheel axles which have their axle bearing housings guided in axle bearing guiding means of the bogie in vertical and horizontal direction for cushioning and absorbing transverse shocks occurring during the drive of the bogie. The helical springs are arranged on one side of each axle bearing housing between the axle bearing guiding means and the axle bearing housing, whereas on the other side the upper spring dish is through a spring link linked to the axle guiding means and acts upon a pushrod displaceably mounted in the axle bearing guiding means and is adapted to be pressed against the axle bearing housing through friction lining which for purposes of differently cushioning the vertical and horizontal movements of the axle bearing housing comprises different friction surfaces and is arranged between the pushrod and the axle bearing housing on one hand and between the axle bearing guiding means and the axle bearing housing on the other hand.
