Abstract
The utility model discloses a kind of turbosupercharger vibration and noise reducing structure; Comprise waste gas valve, valve mounting plate, turbine shroud; Turbine shroud has turbine shroud relief opening; Exhaust gas valve family of power and influence mounting plate and waste gas valve are fastenedly connected, and waste gas valve and turbine shroud relief opening seal to contact and coordinate; Exhaust gas valve family of power and influence mounting plate moves and controls to drive exhaust gas valve door to open and close; It is characterized in that: waste gas valve coordinates with turbine shroud relief opening bias.Advantage is: avoid waste gas valve exciting, eliminate cause due to waste gas valve exciting waste gas valve, valve mounting plate, lock ring, turbine shroud relief opening wearing and tearing; Solve the problem that the turbocharger performance that causes due to exhaust gas bypass system wear declines.Alleviate waste gas valve operationally noise.
Description
Technical field
The utility model belongs to turbo-charger technical field, relates to a kind of turbosupercharger vibration and noise reducing structure, particularly relates to the vibration and noise reducing structure that a kind of turbosupercharger exhaust gas by-pass valve coordinates with turbine shroud bias; Be specially adapted to the design and production of turbosupercharger.
Background technique
Existing turbosupercharger waste gas valve and turbine shroud relief opening concentric fit, its shortcoming is: engine exhaust impacts waste gas valve in a pulsed fashion, in the process of waste gas valve opening, waste gas valve and turbine shroud relief opening concentric fit, pressure uniform distribution on waste gas valve, under the impact of pulsating pressure, can there is exciting in waste gas valve; Such exciting, cause waste gas valve and valve mounting plate, valve mounting plate and lock ring on the one hand, constantly collide between waste gas valve and turbine shroud relief opening, thus cause the wearing and tearing of waste gas valve, valve mounting plate, lock ring, reduce turbosupercharger working life and performance thereof; Produce a large amount of noise on the other hand.
Summary of the invention
The utility model discloses a kind of turbosupercharger vibration and noise reducing structure, can occur to produce exciting by pulse back blast to solve waste gas valve in prior art; Cause the wearing and tearing of waste gas valve, valve mounting plate, lock ring, reduce turbosupercharger working life and performance thereof; Produce the problems such as a large amount of noises.
The utility model comprises waste gas valve, valve mounting plate, turbine shroud; Turbine shroud has turbine shroud relief opening; Exhaust gas valve family of power and influence mounting plate and waste gas valve are fastenedly connected, and waste gas valve and turbine shroud relief opening seal to contact and coordinate; Exhaust gas valve family of power and influence mounting plate moves and controls to drive exhaust gas valve door to open and close; Waste gas valve coordinates with turbine shroud relief opening bias; Due to waste gas valve and turbine shroud relief opening bias coordinates, waste gas valve open, closedown process in, under the effect of exhaust gas pulse pressure, the discontinuity on waste gas valve; Avoid the exciting of waste gas valve under pulsating pressure.
The utility model waste gas valve coordinates apart between 0.5mm----2mm with turbine shroud relief opening bias.
The utility model good effect is: avoid waste gas valve exciting, eliminate cause due to waste gas valve exciting waste gas valve, valve mounting plate, lock ring, turbine shroud relief opening wearing and tearing; Solve the problem that the turbocharger performance that causes due to exhaust gas bypass system wear declines.Alleviate waste gas valve operationally noise.
Accompanying drawing explanation
Fig. 1 is prior art turbosupercharger exhaust gas by-pass valve and turbine shroud cooperating structure schematic diagram;
Fig. 2 is the utility model turbosupercharger exhaust gas by-pass valve and turbine shroud fit system schematic diagram;
In figure: 1 waste gas valve, 2 lock rings, 3 valve mounting plates, 4 turbine shrouds, 4a turbine shroud relief opening, h throw of eccentric.
embodiment:
An embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The utility model first embodiment is as shown in Figure 2: comprise waste gas valve 1, lock ring 2, valve mounting plate 3, turbine shroud 4; Exhaust gas valve family of power and influence mounting plate 3 and waste gas valve 1 are fastenedly connected, waste gas valve 1 has installation connection cylinder end and there is flange, the mounting hole end face that lock ring 2 is arranged on valve mounting plate 3 connects between cylinder end flange with waste gas valve 1 is installed, the installation be fixed on waste gas valve 1 connects on cylinder, the connection of locking valve mounting plate 3 and waste gas valve 1; Turbine shroud 4 has turbine shroud relief opening 4a; Waste gas valve 1 seals to contact with turbine shroud relief opening 4a and coordinates; Exhaust gas valve family of power and influence mounting plate 3 moves and drives exhaust gas valve door 1 to open; Waste gas valve 1 coordinates with turbine shroud relief opening 4a bias; Waste gas valve 1 coordinates distance h to be 0.5mm with turbine shroud relief opening 4a bias.Coordinated by the bias of waste gas valve 1 with turbine shroud relief opening 4a, make waste gas valve 1 in the whole process of unlatching, closedown, under the effect of exhaust gas pulse pressure, stressed on waste gas valve 1 is uneven, avoids the exciting of waste gas valve 1 under pulsating pressure.
The utility model second embodiment waste gas valve 1 coordinates distance h to be 0.8mm with turbine shroud relief opening 4a bias.
The utility model the 3rd embodiment's waste gas valve 1 coordinates distance h to be 2mm with turbine shroud relief opening 4a bias.
Listed a series of detailed descriptions are only illustrating for the utility model feasibility mode of execution; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model equivalent implementations of doing of essence or change all should be included within protection domain of the present utility model.
