Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of turbocharger intake structure, and in particular to a turbocharger intake structure with adjustable blade angle. Background Technology
[0002] In the field of turbocharger technology, the adjustable blade angle turbocharger intake structure is a key technology for optimizing engine performance under all operating conditions. The core of this structure lies in the integration of an adjustable guide vane system at the compressor intake end, which, driven by an electronically controlled or hydraulic actuator, enables precise and dynamic adjustment of the blade angle.
[0003] However, this technology faces a long-standing structural drawback in practical application and maintenance. Existing adjustable blade angle intake structures typically encapsulate the precision blade drive assembly permanently within a single metal intake housing, and rigidly connect it to the intake piping using numerous bolts.
[0004] This makes the disassembly process extremely inconvenient. When it is necessary to calibrate the blade angle, clean carbon deposits, or replace worn parts, technicians must use special tools and spend a lot of time and effort to disassemble numerous fasteners in order to separate the intake pipe from the turbocharger body and then maintain its internal adjustment mechanism.
[0005] Therefore, while existing turbocharger inlet structures with adjustable blade angles exhibit excellent aerodynamic performance, their inherent design flaw of not being able to quickly disassemble the inlet pipe increases the difficulty of maintenance. Thus, there is an urgent need for an adjustable blade turbocharger inlet structure that allows for easy disassembly of the inlet pipe. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable blade angle turbocharger intake structure.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable blade angle turbocharger intake structure includes a turbocharger body, wherein adjustable blades are disposed inside the turbocharger body, a mounting base is fixedly disposed on the top of the turbocharger body, and a detachable intake pipe is assembled inside the mounting base; a locking mounting ring is assembled above the intake pipe, and multiple arc-shaped plates are fixedly disposed on the outer side of the mounting base, and the arc-shaped plates and the mounting ring are locked together by threaded engagement.
[0008] Furthermore, in a preferred configuration, a side ring is fixedly provided on the inner wall of the mounting base, and the mounting base is adapted to the air intake pipe.
[0009] In addition, a preferred structure is that the outer wall of the top of the mounting base is fixedly provided with multiple arc-shaped plates, and the inner wall of the arc-shaped plates is provided with multiple continuous internal threaded grooves.
[0010] Furthermore, in a preferred configuration, the outer wall of the mounting ring is provided with an external thread, and the external thread and the internal thread groove are adapted to engage.
[0011] Furthermore, in a preferred configuration, a sub-rough pad is fixedly laid on the top of the mounting base, and a fixed female rough pad is fitted to the bottom of the mounting ring corresponding to the sub-rough pad.
[0012] In addition, a preferred structure is that a positioning element is fixedly provided on the outer wall of the air intake pipe, and a positioning cavity is provided on the top of the mounting base corresponding to the positioning element.
[0013] The beneficial effects of this utility model are as follows: the positioning component and the positioning cavity can achieve quick centering of the intake pipe; the thread engagement between the mounting ring and the arc plate can achieve quick installation and removal of the intake pipe; and the frictional self-locking effect of the sub-rough pad and the nut rough pad enhances the locking reliability, thus reducing the difficulty and time cost for users to maintain the regulating blades.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-5An adjustable blade angle turbocharger intake structure includes a turbocharger body 1, with adjustable blades inside the turbocharger body 1. A mounting base 11 is fixedly mounted on the top of the turbocharger body 1, and a detachable intake pipe 3 is assembled inside the mounting base 11. A locking mounting ring 2 is mounted above the intake pipe 3. Multiple arc-shaped plates 14 are fixedly mounted on the outer side of the mounting base 11, and the arc-shaped plates 14 and the mounting ring 2 are locked together by threaded engagement.
[0018] A side ring 12 is fixedly provided on the inner wall of the mounting base 11, and the mounting base 11 is adapted to the air intake pipe 3. The inner wall diameter of the mounting base 11 is the same as the outer wall diameter of the air intake pipe 3, which allows the air intake pipe 3 to be stably assembled on the mounting base 11.
[0019] The mounting base 11 has multiple arc-shaped plates 14 fixedly mounted on its outer wall, and multiple continuous internal threaded grooves 15 are formed on the inner wall of the arc-shaped plates 14. The mounting ring 2 has an external thread 22 on its outer wall, which meshes with the internal threaded groove 15. The mating engagement between the external thread 22 and the internal threaded groove 15 secures the mounting ring 2, allowing it to be stably locked and pressed against the positioning member 31. It is worth noting that a prior art thread self-locking mechanism is used between the external thread 22 and the internal threaded groove 15 to ensure the stability of the thread engagement; this is prior art and will not be elaborated upon further.
[0020] The mounting base 11 has a sub-rough pad 111 fixedly laid on its top, and the mounting ring 2 has a fixed female rough pad 21 fitted to the bottom of the sub-rough pad 111. The fitted arrangement between the sub-rough pad 111 and the female rough pad 21 can improve the stability of the mounting ring 2 when it is locked, so as to further prevent the mounting ring 2 from rotating after locking.
[0021] The outer wall of the air intake pipe 3 is fixedly provided with a positioning component 31, and the top of the mounting base 11 is adapted to the positioning component 31 to form a positioning cavity 13.
[0022] In this embodiment, the turbocharger body 1 is provided with adjustable blades, which is prior art and not a major technical problem to be solved in this technical solution, so it will not be described in detail in this application.
[0023] Furthermore, when it is necessary to inspect the blades inside the turbocharger body 1, simply rotate the mounting ring 2 to remove it by rotating it upwards through the thread. Then, simply pull the intake pipe 3 upwards to remove it, thus facilitating the inspection and maintenance of the blades inside the turbocharger body 1.
[0024] After maintenance, simply assemble the intake pipe 3 onto the mounting base 11. When the positioning parts 31 on the intake pipe 3 are properly engaged within the positioning cavity 13, the end of the intake pipe 3 will also be in contact with the side ring 12. Then, the user simply needs to lock the positioning ring 2 onto the positioning parts 31 using a threaded engagement. This locks the intake pipe 3 in place, allowing for its reinstallation.
[0025] Furthermore, through the thread self-locking mechanism between the external thread 22 and the internal thread groove 15, and in conjunction with the matching arrangement between the sub-rough pad 111 and the female rough pad 21, the friction required for the mounting ring 2 to rotate can be further increased, thereby improving the locking ability of the mounting ring 2 and preventing it from loosening under extreme vibration conditions.
[0026] In this invention, the positioning component 31 and the positioning cavity 13 cooperate to achieve quick alignment of the intake pipe 3, and the threaded engagement between the mounting ring 2 and the arc plate 14 enables quick installation and removal of the intake pipe 3. The frictional self-locking effect of the sub-rough pad 111 and the female rough pad 21 enhances the locking reliability, thus reducing the difficulty and time cost for users to maintain the blades.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
