Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turbocharger, in particular to a turbocharger device. BACKGROUND

[0002] The turbocharger is a mechanical device that uses the energy of the exhaust gas to further pressurize, which uses the energy of the engine exhaust gas to drive the turbine in the turbine box to rotate, and the turbine drives the coaxial compressor impeller to work. Fresh air enters the compressor through the air filter, and the compressor impeller rotates to compress fresh air to achieve the effect of pressurization. Therefore, the turbocharger can effectively recover and utilize the energy of the exhaust gas, increase the amount of air in the cylinder under the same displacement, optimize the combustion process, and improve the working efficiency of the internal combustion engine, becoming an indispensable device for modern engines to improve power, save oil, reduce consumption and improve emissions. VGT (Variable Geometry Turbocharger) can dynamically adjust by changing the angle of the guide vane in the turbine housing or by changing the cross-sectional area of the exhaust inlet through the sliding nozzle ring. At low speed, the guide vane angle is small or the flow passage cross-sectional area is small, the exhaust passage is narrow, the exhaust flow rate is accelerated, and the turbine blades are impacted more violently, so that the turbine can rotate faster, effectively reducing the turbine lag and improving the torque output at low speed. At high speed, the guide vane angle is large or the flow passage cross-sectional area is large, the exhaust passage is wide, and the exhaust gas flows more smoothly, which is beneficial to improve the power output of the engine at high speed and improve the economy. In the prior art, the actuator output end is connected with the VGT dial ring, which rotates under the drive of the actuator. The dial ring is also connected with the vane assembly, thereby driving the vane assembly to rotate to achieve the purpose of adjusting the vane opening. Since the dial ring and the mounting base are connected in rotation, in order to limit the rotation amplitude of the dial ring, a limiting groove is arranged on the mounting base, and a limiting protruding structure matched with the limiting groove is arranged on the dial ring to achieve the limiting purpose.

[0003] However, the prior art has the following disadvantages: after long-term work, the limiting structure is prone to deformation and failure due to friction loss and long-term collision, thereby weakening the limiting effect of the rotation amplitude of the dial ring, causing the nozzle ring to be prone to failure during use; in addition, since the turbocharger operates in a high-temperature and high-speed environment, the turbine shaft and its connected parts will produce axial movement due to thermal expansion and stress, therefore, the axial movement of the dial ring cannot be effectively controlled, and excessive movement will cause excessive wear and reduce the service life; and during rotation, the dial ring is prone to eccentricity due to uneven stress, wear or assembly tolerance, and eccentricity causes excessive local stress and accelerates wear.

DETAILED DESCRIPTION

[0028] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. The embodiments are not intended to limit the present application. Example One

[0029] Referring to Figures 1 to 10 The present application discloses a turbocharging device, which comprises a shell 1. The turbocharging device further comprises a turbocharging unit, which is accommodated in the shell 1. Specifically, the turbocharging unit comprises a nozzle ring assembly and a turbine assembly 3.

[0030] The nozzle ring assembly comprises a mounting base 20, a blade assembly 21, an actuating ring 22 and a limiting assembly. The actuating ring 22 is coaxial with and movably connected to the mounting base 20. The blade assembly 21 is movably connected to the mounting base 20. Meanwhile, the blade assembly 21 is also connected to the actuating ring 22, so as to rotate under the driving of the actuating ring 22. In detail, a plurality of blade assemblies 21 are arranged along the circumference of the mounting base 20.

[0031] Further, the limiting assembly comprises a first limiting body 23, a second limiting body 24 and a third limiting body 25 arranged on the mounting base 20.

[0032] The geometric center of the triangle formed by the connecting line of the center of the third limiting body 25 and the first limiting body 23 and the second limiting body 24 overlaps with the axis of the mounting base 20; at the same time, along the radial direction of the mounting base 20, the first limiting body 23, the second limiting body 24 and the third limiting body abut against the inner ring of the dial ring 22. In this way, the eccentricity of the dial ring 22 in the rotation process due to uneven force, wear or assembly tolerance can be effectively avoided. Through the cooperation of the dial ring 22 and the first limiting body 23, the second limiting body 24 and the third limiting body 25, the eccentricity trend of the dial ring 22 is inhibited, and the eccentricity trend of the dial ring 22 is compensated to a certain extent, so as to ensure the stability of the rotation center.

[0033] Along the axial direction of the mounting base 20, at least one of the first limiting body 23, the second limiting body 24 and the third limiting body 25 abuts against the dial ring 22. Specifically, the side of the dial ring 22 away from the mounting base 20 is defined as a first surface. In the first embodiment, the first limiting body 23, the second limiting body 24 and the third limiting body 25 all abut against the first surface; in the second embodiment, only the third limiting body 25 abuts against the first surface; in the third embodiment, the first limiting body 23 and the third limiting body 25 abut against the first surface; in the fourth embodiment, the second limiting body 24 and the third limiting body 25 abut against the first surface.

[0034] In this way, the axial movement of the dial ring 22 can be effectively controlled, so as to position the dial ring 22 in the axial direction, improve the structural stability between the dial ring 22 and the mounting base 20, avoid excessive wear between the dial ring 22 and the vane assembly 21 after long-term use, thereby avoiding functional failure, prolonging the service life of the equipment, and ensuring the accuracy and reliability of control.

[0035] In addition, the first limiting body 23 and the second limiting body 24 are respectively arranged adjacent to the two vane assemblies 21; so that the first limiting body 23 and the second limiting body 24 can limit the movement of the vane assembly 21 along the radial direction of the mounting base 20; since the accurate positioning of the vane assembly 21 in the radial direction is crucial when the vane assembly 21 works, which can determine the opening size of the vane, therefore, by limiting the vane assembly 21 through the first limiting body 23 and the second limiting body 24, the opening of the vane can be accurately limited and the opening size is constrained.

[0036] The turbine assembly 3 is coaxially installed on the mounting base 20.

[0037] The turbocharging device further comprises an execution unit 4, which outputs power to the turbocharging unit to drive the turbocharging unit to act.

[0038] Therefore, the turbocharging device provided by the application is provided with a shell, a turbocharging unit and an execution unit, the turbocharging unit comprises a nozzle ring assembly and a turbine assembly, the nozzle ring assembly comprises a mounting base, a vane assembly, a dial ring and a limiting assembly; the limiting assembly cooperates with the dial ring to effectively control the axial displacement of the dial ring, so as to avoid the connection between the dial ring and the vane assembly from being stuck, excessively worn or functionally failed; in addition, the limiting assembly can also limit the rotation amplitude of the dial ring in the radial direction, thereby limiting the opening of the vane assembly connected thereto, ensuring that the vane can be synchronously and accurately opened or closed to a specified position when rotating, and ensuring that the opening of the vane assembly meets the specified angle range; at the same time, the stability of the rotation center of the dial ring can also be ensured, eccentricity can be avoided, the movement accuracy of the vane assembly can be further improved, the linearity of control can be improved, local stress can be reduced, mechanical wear can be reduced, and the working accuracy and use durability of the turbocharging device can be ensured.

[0039] As a preferred embodiment, the mounting base 20 comprises a cover plate 201, a fixed distance pin 202 and a mounting disc 203, the cover plate 201 and the mounting disc 203 are arranged in the axial direction of the mounting base 20, thereby forming a receiving space. The end of the fixed distance pin 202 is connected to the cover plate 201 and the mounting disc 203 respectively; part of the vane assembly 21 is received in the receiving space.

Therefore, when the dial ring 22 is driven to rotate, one end of the rocker arm 211 rotates synchronously with the dial ring 22, thereby driving the connecting shaft 212 to rotate, so that the adjusting vane 210 located at the other end of the connecting shaft 212 rotates to adjust the size of the intake air.

[0042] Further, the dial ring 22 is provided with mounting grooves for assembling the vane assemblies 21, which are arranged at the inner side edges of the dial ring 22.

It should be noted that the number of the mounting grooves is consistent with the number of the vane assemblies 21, and each vane assembly 21 can be matched with one mounting groove. In this way, it can be ensured that all the vane assemblies 21 can rotate synchronously, and then accurately rotate to the specified position. In this way, the inconsistent vane opening caused by the radial misalignment can be avoided, and the turbine efficiency caused by the uneven distribution of gas flow can also be avoided; the movement track of the adjusting vane 210 in the transmission process is unique and controllable, and the shaking or abnormal sound caused by the virtual position can be prevented.

The second limiting column 240 is mounted on the mounting disc 203, and the second end piece 241 is connected to the end of the second limiting column 240 and can abut against the first surface of the dial ring 22. Similarly, since the second limiting body 24 is arranged adjacent to one of the vane assemblies 21, when the vane assembly 21 is driven to rotate, the second limiting body 24 can limit the rotation of the vane assembly 21.

[0045] The third limiting body 25 comprises a third limiting column 250 and a third end piece 251, the projection area of the third end piece 251 is greater than that of the third limiting column 250 in the axial direction of the third limiting body 25, the third limiting column 250 is installed on the mounting disc 203, the third end piece 251 is connected to the end of the third limiting column 250, and the third end piece 251 can abut against the first surface of the dial ring 22.
