Problems solved by technology

[0002] In the existing one-shaft two-machine horizontal vehicle turbocharger, the bearings installed between the rotating shaft and the bearing housing are separate floating bearings and thrust bearings. Currently, separate floating bearings and thrust bearings exist. The disadvantages are: high cost, troublesome installation, complex oil supply structure to provide lubricating oil to bearings; strict oil supply pressure requirements for lubricating oil, large flow rate, high pressure, good cleanliness and low oil temperature for lubricating oil

Embodiment Construction

[0013] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0014] see figure 1 , Figure 5

[0015] The one-shaft two-machine horizontal vehicle turbocharger provided by the present invention is a one-shaft two-machine type, and the two sides of the bearing shell 7 it has are respectively connected with a compressor casing 3, and each compressor casing 3 passes through the The heat shield 10 is connected and paired with a turbine casing 1 . The inner hole of the bearing shell 7 is equipped with a rotating shaft 6, and the two ends of the rotating shaft 6 are respectively located in the paired compressor shell 3 and the turbine shell 1 on both sides of the bearing shell 7, and the compressor impeller 9 in each compressor 3 shell And the turbine wheel 2 that has in each turbine casing 1 is contained on the rotating shaft 6. The two ends of bearing housing 7 are also equipped with bearing cover 4 respectively, are provid...

Abstract

Provided is a one-shaft two-unit horizontal turbocharger for a vehicle. Both sides of a bearing shell are connected to compressor casings respectively connected to a turbine housing. A rotating shaft is mounted in the bearing shell in a penetration mode. A compressor impeller and a turbine impeller are mounted on the rotating shaft. Bearing caps are mounted at both ends of the bearing shell. An oil slinger is arranged between the bearing caps and the rotating shaft. Both end openings of an inner opening of the bearing shell are respectively provided with a floating bearing with a blocking shoulder. The floating bearings are in clearance fit with the rotating shaft and the bearing shell. Both end openings of the bearing shell are provided with bosses. The blocking shoulder of each of the floating bearings is arranged between the boss at one end of the bearing shell and one of the oil slingers. The bearing shell is provided with an oil inlet. The lubricating oil enters the bearing shell from the oil inlet and then enters the portion between the floating bearings and the rotating shaft and the bearing shell to achieve axial oil feeding, so that the floating bearings are in an ideal suspension state in the work to achieve the ideal lubrication effect. Furthermore, the floating bearings play a role of thrust bearings as well as floating bearings, so that the structure is greatly simplified.

Description

technical field [0001] The invention relates to a vehicle supercharger, in particular to a one-shaft two-machine horizontal vehicle turbocharger. Background technique [0002] In the existing one-shaft two-machine horizontal vehicle turbocharger, the bearings installed between the rotating shaft and the bearing housing are separate floating bearings and thrust bearings. Currently, separate floating bearings and thrust bearings exist. The disadvantages are: high cost, troublesome installation, complex oil supply structure to provide lubricating oil to bearings; strict oil supply pressure requirements for lubricating oil, high flow rate, high pressure, good cleanliness and low oil temperature for lubricating oil. Contents of the invention [0003] The object of the present invention is to provide a kind of one-shaft two-machine horizontal turbocharger for vehicles, the supporting structure of the rotating shaft of the turbocharger for vehicles is simple, reliable, stable in ...
