Embodiment Construction

[0015] figure 1 A perspective view of a turbocharger 1 comprising a turbine 2 and a compressor 3 is shown. figure 1 The turbine 2 shown in is a radial turbine, and figure 1 The compressor 3 shown in is a radial compressor. In the turbine, the exhaust gas is expanded and the energy extracted in the process is used to compress the charge air in the compressor 3 .

[0016] exist figure 1 , the turbine inflow housing 6 and the support housing 7 of the turbine 2 are shown, wherein the turbine inflow housing 6 and the support housing 7 are connected to each other via a fastening ring 8 which is also described as a clamping jaw . The fastening ring 8 is screwed to the turbine inflow casing 6 by means of several fastening screws 4 and fastening nuts 9 in such a way that, in the assembled state, the fastening ring 8 surrounds the bearing casing in sections 7 to engage the section 10 and thus mount the bearing housing 7 on the turbine inflow housing 6 . The compressor housing 5 of...

Abstract

A radial turbine of a turbocharger for expanding a medium, comprises a turbine inlet housing and a bearing housing adjoining the turbine inlet housing. A turbine rotor comprises movable blades, a guide device including adjustable guide vanes positioned on the upstream of the movable blades in a flow direction of to-be-expanded medium, and an adjusting device adjusting the guide vanes of the guidedevice, wherein each guide vane has a guide vane body and a guide vane pin; the adjusting device has a guide ring capable of positioning again; the guide ring is linked to the guide vane pin of the guide vane via a first control rod; the adjusting device has an actuating shaft passing through the bearing housing; the actuating shaft is linked to the guide ring on the first end and linked to a second control rod on a second end; the first end of the actuating shaft linked to the guide ring has an eccentric body; and the eccentric body is linked with the guide ring.

Description

technical field [0001] The invention relates to a radial turbine of a turbocharger and to a turbocharger. Background technique [0002] A radial turbine of an exhaust-gas turbocharger with a guide device comprising adjustable guide vanes is known from DE 103 11 205 B3. Each guide vane comprises a guide blade leaf and a guide blade pin, wherein the guide vane can be adjusted by means of an adjusting device. The adjustment device comprises a guide ring, wherein the guide vane pin of each adjustable guide vane is coupled to the guide ring by means of a respective first control rod. By twisting the guide ring in the circumferential direction, the guide vanes can be finally adjusted, wherein the first control lever converts the movement of the guide ring into the movement of the guide vanes. The guide ring of the adjusting device is positioned in the housing, ie between the turbine inflow housing and the support housing. The rotation of the guide ring is initiated externally v...
