Description

Technical Field

[0001] This utility model relates to the field of turbocharger-related products, specifically a noise reduction device for turbochargers. Background Technology

[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of the exhaust gases from the engine to drive a turbine within the turbine housing. The turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter and forces it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously. The impeller then compresses more air into the cylinders. The increased air pressure and density allow for the combustion of more fuel. By increasing the fuel quantity and adjusting the engine speed, the engine's output power can be increased.

[0003] When a turbocharger is suddenly started, it is subjected to sudden vibration, which can easily damage the turbocharger. During the operation of the turbocharger, the rapidly rotating turbine causes the turbocharger to vibrate, which will resonate with other parts and produce a lot of noise. Utility Model Content

[0004] The purpose of this invention is to provide a noise reduction device for a turbocharger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise reduction device for a turbocharger, comprising a mounting base and a turbocharger body. A support plate is provided inside the mounting base, and the support plate is fixedly connected to the mounting base via a damping shock absorber. A fixing plate is fixedly attached to the bottom of the turbocharger body, and the fixing plate is fixedly connected to the support plate. Support cylinders are fixedly connected to the inner walls of both sides of the mounting base. A traction rod is rotatably inserted into the support cylinder, and stop blocks are fixedly connected to both ends of the traction rod. Torsion springs are sleeved on both ends of the traction rod, and the two ends of the torsion springs are fixedly connected to the support cylinder and the stop blocks, respectively. A gear is fixedly sleeved on the traction rod, and a meshing toothed plate is provided on one side of the gear. A wedge-shaped plate is provided on one side of the toothed plate, and the wedge-shaped plate is fixedly connected to the support plate.

[0006] As a preferred embodiment of this utility model, a limiting plate is fixed below the toothed plate, and a limiting groove corresponding to the position of the limiting plate is provided at the bottom inner side of the mounting base. A sliding rod is fixed in the limiting groove, and the limiting plate is slidably sleeved on the sliding rod.

[0007] As a preferred embodiment of this utility model, both sides of the support cylinder are provided with through openings, and bearings are fixed inside the through openings, with the traction rod fixedly inserted into the bearings.

[0008] As a preferred embodiment of this invention, one end of the toothed plate is rotatably connected to a pressure wheel, and the edge of the pressure wheel contacts the wedge plate.

[0009] As a preferred embodiment of this utility model, the fixing plate is provided with mounting holes at all four corners, and locking screws are inserted into the mounting holes. The fixing plate is fixed to the support plate by the locking screws.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The noise reduction device of this turbocharger uses a damping shock absorber to achieve buffer support for the support plate. The fixing plate on the bottom of the turbocharger body is fixed to the support plate. When the turbocharger body vibrates during operation, the wedge plate on the bottom of the support plate can press against one end of the toothed plate. When the toothed plate moves, it rotates the meshing gear, thereby realizing the rotation of the traction rod. When the traction rod rotates, the stop blocks on both ends will rotate along with it, thereby causing the torsion spring to rotate. The torsion spring generates rotational torque to achieve shock absorption.

[0012] The noise reduction device for this turbocharger, through the installation of buffer and vibration damping components, can reduce vibration and noise in the turbocharger, protecting the turbocharger while reducing noise. Attached Figure Description

A fixing plate 5 is fixedly fixed to the bottom of the turbocharger body 2, and the fixing plate 5 is fixedly connected to the support plate 3. Support cylinders 6 are fixedly connected to the inner walls of both sides of the mounting base 1. A traction rod 7 is rotatably inserted into the support cylinder 6. Stop blocks 8 are fixedly connected to both ends of the traction rod 7. Torsion springs 9 are sleeved on both ends of the traction rod 7, and the two ends of the torsion springs 9 are fixedly connected to the support cylinder 6 and the stop blocks 8 respectively. A torsion spring 9 is fixedly sleeved on the traction rod 7. There is a gear 10, and a meshing toothed plate 11 is provided on one side of the gear 10. A wedge plate 12 is provided on one side of the toothed plate 11. The wedge plate 12 is fixedly connected to the support plate 3. Specifically, the damping shock absorber 4 realizes the buffer support of the support plate 3. The fixing plate 5 on the bottom of the turbocharger body 2 is fixed on the support plate 3. When the turbocharger body 2 vibrates during operation, the wedge plate 12 on the bottom of the support plate 3 can press against one end of the toothed plate 11 to move. When the toothed plate 11 moves, it will rotate the meshing gear 10, thereby realizing the rotation of the traction rod 7. When the traction rod 7 rotates, the stop blocks 8 on both ends will rotate accordingly, thereby causing the torsion spring 9 to rotate. The torsion spring 9 generates rotational torque to realize shock absorption.

[0025] As a technical optimization of this utility model, the pressure roller 16 is used to achieve pressure between itself and the wedge plate 12, thereby reducing the frictional resistance during pressure application.

[0026] In this embodiment, mounting holes are provided at all four corners of the fixing plate 5, and locking screws 17 are inserted into the mounting holes. The fixing plate 5 is fixed to the support plate 3 by the locking screws 17.

[0027] As a technical optimization of this utility model, the installation and fixation between the fixing plate 5 and the support plate 3 is achieved by locking screw 17.

The fixing plate 5 on the bottom of the turbocharger body 2 is fixed on the support plate 3. When the turbocharger body 2 vibrates during operation, the wedge plate 12 on the bottom of the support plate 3 can press against one end of the toothed plate 11. When the toothed plate 11 moves, it rotates the meshing gear 10, thereby realizing the rotation of the traction rod 7. When the traction rod 7 rotates, the stop blocks 8 on both ends will rotate accordingly, thereby causing the torsion spring 9 to rotate. The torsion spring 9 generates rotational torque to achieve shock absorption.
