Abstract
Abstract A bogie with a torsion-soft corner-stiff frame for high speed rail vehicles with a wear-resistant means interconnecting the central areas of the longitudinal beams of the bogie together with one wear-resistant means each interconnecting the longitudinal beam ends. Of the wear-resistant means, that means which is located within the region of the vertical transverse plane is designed as an intermediate joint permitting movements solely about the y-axis, whereas the wear-resistant means at the ends form components of horizontal spring leaves which form head pieces of the bogie. The ends of said spring leaves are in a corner-stiff manner connected to stiff corner pieces arranged at the ends of the longitudinal beams.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
212 words
A bogie with pivoting frame members for high-speed rail vehicles formed by two rigid bogie longitudinal beams having lateral extensions which are pivotal in vertical direction relative to each other though in the horizontal plane being rigid and firm relative to each other, in which said longitudinal beams are interconnected by elastic wear-resistant means which are arranged symmetrically to and in the region of the vertical central transverse plane of the bogie, and in which said bogie has at least one pivot point for the pivoting frame members with the upper structure of the rail vehicle and with each axle bearing having axle bearing guiding means, the improvement in combination therewith comprising a wear-resistant means interconnecting the central areas of the bogie longitudinal beams together with one wear-resistant means each interconnecting the longitudinal beam ends by way of the lateral extensions, and that said wear-resistant means which is located within the region of the vertical transverse plane is designed as an intermediate joint permitting movements solely about the vertical axis whereas the wear-resistant means at the ends form components of horizontal spring leaves which form the lateral extensions of the bogie, the ends of said spring leaves being connected to the rigid lateral extensions arranged at the ends of said longitudinal means.
Claim 2
Dependent Claim
212 words
A bogie with pivoting frame members for high-speed rail vehicles formed by two rigid bogie longitudinal beams having lateral extensions which are pivotal in vertical direction relative to each other though in the horizontal plane being rigid and firm relative to each other, in which said longitudinal beams are interconnected by elastic wear-resistant means which are arranged symmetrically to and in the region of the vertical central transverse plane of the bogie, and in which said bogie has at least one pivot point for the pivoting frame members with the upper structure of the rail vehicle and with each axle bearing having axle bearing guiding means, the improvement in combination therewith comprising a wear-resistant means interconnecting the central areas of the bogie longitudinal beams together with one wear-resistant means each interconnecting the longitudinal beam ends by way of the lateral extensions, and that said wear-resistant means which is located within the region of the vertical transverse plane is designed as an intermediate joint permitting movements solely about the vertical axis whereas the wear-resistant means at the ends form components of horizontal spring leaves which form the lateral extensions of the bogie, the ends of said spring leaves being connected to the rigid lateral extensions arranged at the ends of said longitudinal means.
Claim 3
Dependent Claim
105 words
A bogie in combination according to claim 1 comprising: first spring means arranged between said longitudinal beams and said axle bearing housing, axle bearing guiding means operatively separated from said first spring means; second spring means formed by supporting springs and operable to convey the load of the car box onto the longitudinal beams at both sides as close as possible to the line of intersection between the vertical gravity plane of the respective longitudinal beam with the vertical central transverse plane of said bogie; and a pivot point independent of vertical forces and located between the upper structure on the bogie and said bogie.
Claim 4
Dependent Claim
