Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is that the relevant enterprises all use the VGT shift fork to drive the dial, the dial drives the shift fork to rotate, the structure of the nozzle ring to adjust the blade opening, and the disk and the back cover are installed during the blade switch process. As a fixed support structure, the structure is complex and the adjustment effect is poor

Embodiment 1

[0039] refer to Figure 1-8, this embodiment provides a variable cross-section nozzle ring that drives the installation disk to adjust the opening of the biaxial blades, including a fixed disk 100, wherein the fixed disk 100 is an annular disk-shaped structure used for installation and fixing in the middle of the VGT assembly, A through-hole 101 is provided to form a ring; the mounting plate 200, the mounting plate 200 is an annular plate-shaped structure, is installed in the through hole 101 of the fixed plate 100, and is matched with the through hole of the fixed plate 100, and the mounting plate 200 is set There are several first shaft grooves 201 evenly distributed along the circumference; the back cover 300, the back cover 300 is an annular disc structure, the back cover 300 is located on one side of the fixed plate 100, and the back cover 300 is provided with several evenly distributed along the circumference The second shaft groove 301; and, the blade 400 is provided wi...

Embodiment 2

[0049] refer to Figure 9 , 10 , is the second embodiment of the present invention, which is based on the previous embodiment, and differs from the previous embodiment in that the first shaft groove 201 is a long groove, the second shaft groove 301 is a circular groove, and the first shaft groove 301 is a circular groove. The shaft groove 201 extends along the radial direction of the mounting plate 200, that is, the first shaft groove 201 is a sliding groove,

[0050] For the design of the sliding grooves of the blades on the mounting plate, it is necessary to ensure that the blades can still be driven through the mounting plate in the case of a small opening. Therefore, it is necessary to ensure that in the rotation range of the blade design, point c is on the extension line of point bd at the minimum opening.

[0051] The connection line L1 between the blade axis a (ie, the second blade axis 402) and the VGT axis d, the connection line L2 between the blade axis b (ie, the ...

Abstract

The invention discloses a variable-section nozzle ring for driving a mounting disc to adjust the opening degree of double-shaft blades. The variable-section nozzle ring comprises a fixed disc with a through hole, a mounting disc of an annular disc-shaped structure and mounted in the through hole of the fixed disc, a rear cover of an annular disc-shaped structure and blades; a plurality of first shaft grooves which are uniformly distributed along the circumference are formed in the mounting disc; the rear cover is located on one side of the fixed disc, and the rear cover is provided with a plurality of second shaft grooves which are evenly distributed along the circumference; and the blades are provided with first blade shafts and second blade shafts, the first blade shafts and the second blade shafts are located on the two sides of blade bodies respectively, the axes of the first blade shafts does not coincide with the axes of the second blade shafts, the first blade shafts are embedded into the first shaft grooves, and the second blade shafts are embedded into the second shaft grooves. The double-shaft blades are driven by a driving disc, so that part shifting forks are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of superchargers, in particular to a variable-section nozzle ring that drives a mounting plate to adjust the opening of biaxial blades. Background technique [0002] In order to solve the turbo hysteresis, so that the turbocharged engine can ensure a good supercharging effect at high and low speeds, VGT (Variable Geometry Turbocharger) or VNT variable cross-section turbocharging technology came into being. In the field of diesel engines, VGT variable cross-section turbocharging technology has already been widely used. Since the exhaust temperature of gasoline engines is much higher than that of diesel engines, reaching about 1000°C (about 600°C for diesel engines), and the hardware materials used in VGT can hardly withstand such a high temperature environment, so this technology is delayed. Failed to apply on gasoline engine. In recent years, BorgWarner and Porsche have jointly overcome this problem and used high-te...
