Description

Technical Field

[0001] The utility model relates to the technical field of engines, and more specifically, to an anti-extrusion oil pipe for a turbocharger. Background Art

[0002] The turbocharger is installed on the exhaust side of the engine. Therefore, the working temperature of the turbocharger is very high, and the rotational speed of the rotor during operation is extremely high, reaching hundreds of thousands of revolutions per minute. Engine oil is required for lubrication to ensure normal operation.

[0003] In order to ensure reliability, the existing turbochargers are made by bending an integral metal pipe, which poses high requirements for manufacturing accuracy. The subsequent installation and disassembly processes are inconvenient, and the vibration during vehicle operation can also damage the metal oil pipe. The working components inside the engine cover have a high temperature inside the room due to long-term operation, which is directly transmitted to the oil pipe, resulting in an increase in the temperature of the lubricating oil inside the oil pipe and a reduction in the lubrication effect.

[0004] After retrieval, the Chinese patent with the application number CN201821045010.7 discloses a turbocharger oil pipe. After the utility model is assembled, the turbo connection pipe and the engine connection pipe at both ends of the turbocharger oil pipe can rotate inside the rubber hose, ensuring the adjustability during installation and disassembly. The assembly process is simple and convenient, and the sealing performance after assembly is good. The rubber hose is arranged inside the heat insulation sleeve, which can effectively protect the rubber hose and also insulate the lubricating oil inside the rubber hose to prevent the lubricating oil temperature from rising and reducing the lubrication effect.

[0005] However, when the above oil pipe is actually used, external forces may squeeze the outside of the oil pipe, resulting in deformation of the shape of the oil pipe. In the case of excessive pressure, it may lead to a reduction in the oil transmission efficiency inside the oil pipe, resulting in a reduction in the service life of the turbocharger.

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The embodiment of the present application discloses an anti-extrusion oil pipe for a turbocharger, which includes an oil pipe main body 1. A corrugated pipe 2 is arranged inside the oil pipe main body 1. A plurality of support columns 3 are fixedly connected inside the corrugated pipe 2. The plurality of support columns 3 are distributed in a circular array inside the oil pipe main body 1. The oil pipe main body 1 is provided with an anti-extrusion mechanism; the anti-extrusion mechanism includes two connecting rings 4. The inner wall of the connecting ring 4 is fixedly connected to the outer side of the oil pipe main body 1. The two connecting rings 4 are symmetrically arranged on the outer side of the oil pipe main body 1. A plurality of outer protection rings 5 are arranged on one side of the connecting ring 4. The plurality of outer protection rings 5 are evenly distributed on one side of the two connecting rings 4. A plurality of sliding grooves 6 are opened on the outer side of the outer protection ring 5. A plurality of connecting rods 7 are slidably connected to the outer protection ring 5. Both ends of the connecting rod 7 are hinged with a movable seat 8. A slider 9 is fixedly connected to the top of the movable seat 8. Two outer shells 10 are fixedly connected to the outer side of the outer protection ring 5. The outer shells 10 are symmetrically distributed on the outer side of the outer protection ring 5. A multi-tooth support ring 11 is fixedly connected inside the outer shell 10. A button 12 is slidably connected inside the multi-tooth support ring 11. A single-tooth support block 13 is slidably connected inside the outer shell 10. One side of the single-tooth support block 13 is movably connected to the outer side of the multi-tooth support ring 11. A spring 14 is fixedly connected to one side of the single-tooth support block 13. A support rod 15 is fixedly connected to the outer side of the single-tooth support block 13. A clamping arm 16 is fixedly connected to one side of the support rod 15. In the bending area of the corrugated pipe 2, the plurality of outer protection rings 5 are bent to a certain extent through the plurality of connecting rods 7 between them. The corresponding movable seats 8 and sliders 9 at both ends of the plurality of connecting rods 7 enable the adjacent two outer protection rings 5 to remain connected. Then, the button 12 is pressed to push the single-tooth support block 13 and the support rod 15 to move inside the outer shell 10, so that the clamping arm 16 can stably support the outer side of the corrugated pipe 2, enabling the external extrusion force to be resisted by the plurality of outer protection rings 5, avoiding the extrusion force acting directly on the oil pipe. At the same time, the plurality of support columns 3 provide a certain support to the inside of the corrugated pipe 2, improving the anti-extrusion effect of the oil pipe.

[0028] Refer to Figure 5As shown in the figure, an oil pipe connection auxiliary mechanism is provided on one side of the oil pipe main body 1. The oil pipe connection auxiliary mechanism includes a connection plate 17. One side of the connection plate 17 is fixedly connected to one side of the oil pipe main body 1. A positioning block 18 is rotatably connected to the outside of the connection plate 17. A clamping ring 19 is fixedly connected to one side of the positioning block 18. A pin 20 is inserted into the clamping ring 19. A sealing gasket 21 is fixedly connected to one side of the connection plate 17. When the connection plate 17 is connected to the turbocharger, the two clamping rings 19 can limit the connection flange of the connection plate 17 and the turbocharger, facilitating the accuracy of subsequent screw fixation of the connection plate 17.

[0029] Refer to Figure 6 As shown in the figure, a connecting plate 22 is fixedly connected to the outside of the oil pipe main body 1. A thread 23 is provided on the other side of the oil pipe main body 1. A sealing ring 24 is fixedly installed on the other side of the oil pipe main body 1, so that the other side of the oil pipe main body 1 is threadedly connected to the engine, and the connection between the oil pipe and the engine is sealed by the sealing ring 24.

[0030] The working principle of the present utility model: During the process of fixing the oil pipe of the turbocharger, first press the corresponding button 12 on the outside of the outer protection ring 5. The button 12 pushes the single-tooth support block 13 to slide in the chute of the multi-tooth support ring 11. Then when the teeth of the single-tooth support block 13 are engaged with the tooth groove on one side of the multi-tooth support ring 11, the spring 14 pushes the single-tooth support block 13 to be limited to one side of the multi-tooth support ring 11. At the same time, the support rod 15 drives the clamping arm 16 to clamp and support the outside of the bellows 2. When protecting the bending area of the bellows 2, the multiple outer protection rings 5 are adjusted according to the bending angle of the oil pipe through the sliding of the connecting rods 7, movable seats 8 and sliders 9 connected between them. Threadedly connect the thread 23 on the other side of the oil pipe main body 1 to the engine. Then rotate the two clamping rings 19 on the outside of the connection plate 17 of one side of the oil pipe through the positioning block 18, and then connect the connection port of the connection plate 17 to the turbocharger. Then the two clamping rings 19 are rotated back to the outside of the connection plate 17 through the positioning block 18 to limit the connection flange of the connection plate 17 and the turbocharger to a certain extent. Then insert the two pins 20 back into the clamping rings 19, and then connect the connection flange of the connection plate 17 and the turbocharger with multiple screws, and limit the two clamping rings 19 so that the oil pipe can be quickly and stably connected;

[0031] When being extruded by the outside world, the multiple outer protection rings 5 support the outside of the bellows 2 to a certain extent, preventing the extrusion force from directly acting on the outside of the bellows 2. At the same time, the multiple support columns 3 inside the bellows 2 improve the compressive capacity of the bellows 2, improving the anti-extrusion effect of the oil pipe.
