1. An exhaust-gas turbocharger (1) comprising a bearing housing (2),a shaft (3) mounted in the bearing housing (2),a compressor wheel (5) arranged on the shaft (3) and a turbine wheel (4) arranged on the shaft (3),a housing component (7) which surrounds the compressor wheel (5) or the turbine wheel (4), anda sealing ring (14) directly between the bearing housing (2) and the housing component (7),wherein the sealing ring (14) is, in order to impart its sealing action, compressed in a direction perpendicular to the shaft (3), and wherein the sealing ring (14) is of V-shaped or U-shaped cross section, wherein the V-shape or U-shape opens in a direction parallel to the shaft (3). 2. The exhaust-gas turbocharger as claimed in claim 1, wherein the shaft has a circumference, and wherein the sealing ring (14) is arranged around the full circumference of the shaft (3). 3. The exhaust-gas turbocharger as claimed in claim 1, wherein a cavity (13) is formed by the bearing housing (2) and the housing component (7), for receiving the sealing ring (14), having a cavity height (21) perpendicular to the shaft (3) and having a cavity width (22) parallel to the shaft (3), wherein the sealing ring (14) has a sealing ring height perpendicular to the shaft (3) and a sealing ring width (23) parallel to the shaft (3), and wherein, in the fully assembled state of the exhaust-gas turbocharger (1), the cavity width (22) is greater than the sealing ring width (23). 4. The exhaust-gas turbocharger as claimed in claim 3, wherein the cavity height (21) is smaller than the sealing ring height of an unmounted sealing ring (14). 5. The exhaust-gas turbocharger as claimed in claim 1, wherein the sealing ring (14) is compressed between a first annular surface (16) of the bearing housing (2) and a second annular surface (19) of the housing component (7), wherein the first and second annular surfaces (16, 19) are arranged parallel to the shaft (3). 6. The exhaust-gas turbocharger as claimed in claim 5, wherein the first annular surface (16) or the second annular surface (19) is delimited at both sides by in each case one projecting wall (17, 18), and the sealing ring (14) can be pre-mounted between the two projecting walls (17, 18). 7. The exhaust-gas turbocharger as claimed in claim 1, further comprising screws between the bearing housing (2) and the housing component (7). 8. The exhaust-gas turbocharger as claimed in claim 1, wherein the housing component (7) is in the form of a turbine housing with an integrated inflow duct (9) for exhaust gas. 9. A method for assembly of an exhaust-gas turbocharger (1), the method comprising: providing a bearing housing (2), wherein the bearing housing (2) is designed for mounting a shaft (3) which connects a turbine wheel (4) to a compressor wheel (5),providing a housing component (7) which surrounds the compressor wheel (5) or the turbine wheel (4),inserting a sealing ring (14) into a groove, which is open in a direction perpendicular to the shaft (3), in the bearing housing (2) or in the housing component (7),pushing the bearing housing (2) and housing component (7) together in a direction parallel to the shaft (3) and simultaneously compressing the sealing ring (14), such that the sealing ring (14) is directly between the bearing housing (2) and the housing component (7), andscrewing the bearing housing (2) and housing component (7) together after the sealing ring (14) has been compressed,wherein the sealing ring (14) is, in order to impart its sealing action, compressed in a direction perpendicular to the shaft (3), and wherein the sealing ring (14) is of V-shaped or U-shaped cross section, wherein the V-shape or U-shape opens in a direction parallel to the shaft (3).
