In order to solve the problem existing for background technique, the utility model have employed following technological scheme: a kind of vehicle turbocharger, comprise the turbine casing connected successively, intermediate and compressor casing, couple axle is equipped with and couple axle two ends extend in turbine casing and compressor casing respectively in described intermediate, one end that described couple axle stretches into turbine casing is arranged with turbine, one end that described couple axle stretches into compressor casing is arranged with impeller, described couple axle is arranged with thrust sleeve respectively, thrust bearing and floating bearing, described intermediate is respectively equipped with oil inlet hole, divide oily runner, go out oil pocket, oil outlet, described thrust bearing is provided with the thrust oilhole of open pore and the oblique couple axle be interconnected, described floating bearing is respectively equipped with lubrication hole and oil drainage hole, described oil inlet hole is communicated in the open pore of thrust bearing and the lubrication hole of floating bearing respectively by a point oily runner, the oil drainage hole of described floating bearing is connected with the oil outlet of intermediate.
By this setting, vehicle turbocharger of the present utility model is by improving intermediate, when passing through at oil inlet hole after the inner oiling of intermediate, lubricant oil can be good at flowing in the thrust oilhole of thrust bearing and the lubrication hole of floating bearing by a point oily runner and enters in the outer wall of couple axle, in couple axle rotation process, lubricant oil also can by oil drainage hole, oil outlet enters into out in oil pocket and circulates successively, thus can be good at the lubrication effect keeping turbosupercharger inside, namely the high-efficiency operation of couple axle can be ensured, to improve the working efficiency of turbosupercharger.
Further setting of the present utility model: described intermediate and turbine are provided with a thermal shield between taking turns and carrying on the back, the couple axle axle root place at described thermal shield axle perforation place is provided with one elastic packing outer shroud.
By this setting, the phenomenon that the setting of thermal shield can avoid intermediate inside temperature too high, to keep the good mobility of lubricant oil, and the setting of elastic packing outer shroud can avoid lubricant oil to leak near the side of turbine.
Further setting of the present utility model: described turbine is equiped with some blades, described some blades are plane and are fixedly connected with turbine is vertical.
By this setting, thus be conducive to the resistance of waste gas in turbine casing reducing motor, to increase the discharge value of gas, gas increased the active force on blade, thus effectively improves the output power of turbosupercharger.
Further setting of the present utility model: described compressor casing is provided with back of the body dish near one end of intermediate, described back of the body dish is located on couple axle by thrust housing jacket casing.
By this setting, the connection being arranged so that compressor casing of back of the body dish and dismantle convenient, facilitates staff better to carry out inspection and maintenance to compressor casing inside simultaneously.
Further setting of the present utility model: described back of the body dish is fixedly connected with the mode that compressor casing is bolted.
By this setting, thus make the connection between back of the body dish and compressor casing more convenient, what make to connect between back of the body dish and compressor casing is also more firm simultaneously.
The beneficial effects of the utility model are: the utility model vehicle turbocharger rational in infrastructure, can be good at keeping inner lubrication effect, to ensure the high-efficiency operation of couple axle, thus are conducive to the working efficiency improving turbosupercharger.
