摘要： An exhaust turbocharger with a variable-nozzle mechanism with fail-safe feature included is provided with which, even if wear of the drive ring supporting part where the supporting elements are in reciprocating sliding or rolling contact with each other under high temperature without lubrication increases, the drive ring can be supported on the nozzle mount on the second supporting part, which enables the drive ring to be always supported rightly on the nozzle mount, and to prevent the occurrence of eccentric rotation or dropping out of the drive ring due to excessive wear of the drive ring supporting part or the occurrence of reduction in engine performance due to malfunctions of the variable-nozzle mechanism such as the error in the relation between the output of the actuator and the nozzle vane opening or the occurrence of breakage of the variable-nozzle mechanism as has been experienced in prior arts.

摘要： A variable-capacity turbine provided with a nozzle adjustment mechanism having a nozzle drive component, a lever and nozzle vanes, all housed at the inner side of a scroll in a turbine casing. This reduces the axial length of the turbine and makes it more compact, and thus easier to install in a car. It also avoids the problem of the center casing becoming too complex. There are fewer assembly and disassembly processes, and the turbine is easier for maintenance. This variable-capacity turbine has a nozzle drive member for the nozzles which is connected to an actuator that causes the drive member to rotate around the shaft turbine and a nozzle adjustment mechanism which includes a number of connectors to link the nozzle drive member to the nozzle vanes. The nozzle adjustment mechanism, which comprises the nozzle drive member and the connectors, is installed in the link chamber provided inside the scroll, and the link chamber providing the nozzle adjustment mechanism is provided at the gas outlet side of the nozzle vanes.

摘要： When changing a nozzle blade angle by rotating a drive ring, a contact load generated between an inner circumferential surface of the drive ring and an outer circumferential surface of a mount can be reduced, allowing the drive ring to rotate smoothly and reducing the amount of wear and a driving force. It is also possible to reduce an impact force, such as engine vibrations, generated at the drive ring when an external force acts, reducing the risk of damage. A plurality of notches (19) are provided at an inner rim of the drive ring (14), and, among inner circumferential surfaces (14a, 14b, 14c, 14d, 14e, 14f, 14g, and 14h) located between the notches (19), when a driving force for rotating the drive ring (14) is applied, the inner diameters of the inner circumferential surfaces (14e, 14f, 14g, and 14h) where the contact load with the outer circumferential surface of a mount becomes large are made larger than the outer diameter of the outer circumferential surface.
