Abstract
The utility model discloses a gasoline engine booster returns oil pipe, include back the oil pipe body and weld at the first ring flange and the second ring flange that go back to oil pipe body both ends respectively, it is in by first metal body and second metal body and connection to return the oil pipe body the hose of weaving between two sections metal bodys constitutes. This time oil pipe can adapt to complicated trend and can avoid leading to the easy damaged problem of body because of the vibration.
Description
Technical field
The utility model relates to the pipeline on a kind of automobile, is specially a kind of return tube of petrol engine supercharger.
Background technique
The petrol engine of turbocharging technology is adopted all to have an oil return pipe of supercharger be connected between cylinder body and pressurized machine.Existing petrol engine supercharger return tube adopts metal tube to become certain shape by tube bender bending usually, and two ends are welded with flange plate or joint again.The deficiency of the return tube of this structure is: in the matching process of some vehicle, due to the arrangement requirement of car load, the trend of oil return pipe of supercharger is very complicated, adopt the oil return pipe of supercharger pipeline bending of all metal tube many, manufacturing process is complicated, accumulative bending tolerance is large, and oil return pipe of supercharger mounting points is fixing, causes assembling difficulty; Adopt the petrol engine of turbocharging technology in addition in running, supercharger speed is high, makes the vibration of oil return pipe of supercharger comparatively large, adopts the oil return pipe of supercharger vibration resistance of all metal tube poor, easily cause pipe shaft to break because of torsional oscillation, cause oil leak.
Summary of the invention
The purpose of this utility model is to provide a kind of petrol engine supercharger return tube, can adapt to complicated trend and can avoid the problem because vibration causes body easily damaged.
Petrol engine supercharger return tube described in the utility model, comprise return tube body and be welded on the first flange plate and second flange plate at return tube body two ends respectively, described return tube body is made up of the first metal tube and the second metal tube and the flexible hose be connected between described two sections of metal tubes, one end and first flange plate of described first metal tube are welded and fixed, its the other end to be plugged on flexible hose and to fix with clip, one end and second flange plate of described second metal tube are welded and fixed, its the other end to be plugged on flexible hose and to fix with clip.
Preferably, outside described flexible hose, heat shield is arranged with.
Preferably, the periphery of one end that described first metal tube is connected with flexible hose has spacing convex closure, the periphery of one end that the second metal tube is connected with flexible hose also has spacing convex closure.
Preferably, described clip is monaural clip.
Preferably, the mouth of pipe place of described second metal tube is provided with O RunddichtringO.
Return tube body described in the utility model adopts flexible flexible hose at middle part, effectively can eliminate the accumulation bending tolerance of bend pipe, adapts to the complicated requirement of line arrangement, and can absorb vibration, solves the problem that metal tubes is easily damaged.In addition, described flexible hose is connected with metal tube by clip, easy to assembly, quick, decreases welding operation, ensure that efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of described flexible hose and heat shield;
Fig. 3 is the assembly structure schematic diagram of described first metal tube and flexible hose;
Fig. 4 is the assembling schematic diagram of described monaural clip.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
Petrol engine supercharger return tube as shown in Figure 1, 2, comprises return tube body and is welded on first flange plate 1 and second flange plate 2 at return tube body two ends respectively.
Described return tube body is made up of the first metal tube 4 and the second metal tube 5 and these the three sections of bodys of flexible hose 3 be connected between described two sections of metal tubes, outside described flexible hose 3, be arranged with heat shield 6, described flexible hose adopts band fiber braiding layer hose construction.The periphery periphery of one end that described first metal tube is connected with flexible hose with one end that spacing convex closure 7, second metal tube is connected with flexible hose also has spacing convex closure 7.
Wherein, one end and first flange plate 1 of described first metal tube 4 are welded and fixed, and the other end is plugged on flexible hose and also fixes with monaural clip 8.Same, one end and second flange plate 2 of the second metal tube 5 are welded and fixed, and its other end is plugged on flexible hose and also fixes with monaural clip 8.First and second metal tubes are identical with the assembling mode of flexible hose, see Fig. 3,4, example is assembled into the first metal tube 4 and flexible hose 3, when assembling, first metal tube 4 is inserted flexible hose 3 until the spacing convex closure 7 on the first metal tube is conflicted with flexible hose, monaural clip 8 is put, then act on monaural clip ear base 81 with special caliper monaural clip is clamped, thus fast, easy first metal tube that achieves is connected closely with between flexible hose.
The mouth of pipe place of stretching out the second flange plate at described second metal tube 5 is provided with O RunddichtringO 51.
First flange plate 1, when assembling, is fixedly connected with pressurized machine with construction bolt 9, is sealed between the first flange plate and pressurized machine by sealing gasket 10 by above-mentioned oil return pipe of supercharger.By construction bolt, the second flange plate 2 is fixedly connected with cylinder body, and carries out radial seal by described O RunddichtringO 51.
