Description
Technical field
The utility model relates to field of turbochargers, especially relates to a kind of turbocharger deflation valve lid.
Background technique
The venting valve gap of the turbosupercharger with exhaust gas by-pass valve is generally valve gap and is flexibly connected with push rod, and this structure, under gas pressure at a high speed, can make valve gap body stressed and acutely swing, thus produces noise, affects car load NVH performance; A kind of structure is also had to comprise valve gap, push rod, the pressing plate of the bending section of push rod is provided with through hole, the bearing pin of valve gap afterbody is embedded in through hole, pressing plate and valve gap are assembled into inclined-plane and sphere-contact, although this structure reduces valve gap by high-speed pneumatic effect vibrations and the rotation preventing valve gap, its complex structure, manufacturability is poor.
Model utility content
The utility model is the above-mentioned deficiency in order to overcome prior art, provides a kind of manufacturability good, safe and reliable and can reduce the venting valve gap of the turbosupercharger of noise.
To achieve these goals, the utility model is by the following technical solutions:
A kind of turbocharger deflation valve lid of the present utility model, comprise push rod, valve gap and be arranged at the rocking arm of push rod end, described rocking arm is provided with the pressing plate relative with valve gap, pressing plate is provided with through hole, described valve gap top is provided with the bearing pin running through through hole, and described bearing pin is socketed with spacing shim through the end winding support of through hole, described bearing pin is socketed with the elastic collar of fitting with clamp surface, described pressing plate and valve gap are plane contact, and spring collar and pressing plate are plane contact.Spacing shim effect closely cooperates between elastic collar and pressing plate, prevents the vibrations of gas pressure bottom flange, thus reduces noise, platen and valve gap are plane contact simultaneously, spring collar and platen are plane contact, and make technique more simple, difficulty of processing reduces.
As preferably, the periphery of described pressing plate is provided with two pressing plate projections, restraining groove is formed between two pressing plate projections, described valve gap periphery is provided with a valve gap projection, in the protruding restraining groove between two pressing plate projections of described valve gap, between the inner side surface of restraining groove and corresponding valve gap projection, be provided with gap.Such pressing plate projection is limited between two valve gap projections, is provided with gap simultaneously, prevents valve gap from rotating, thus reduce noise between valve gap projection and projection.
As preferably, described gap is 0.5 ~ 2mm.
As preferably, described elastic collar is bowl-type, and the large Transverse plane of elastic collar and valve gap are close to, and the little Transverse plane of elastic collar and spacing shim are close to.
As preferably, the small end of described elastic collar and the axial clearance of pressing plate are 0.3 ~ 1.5mm.
Therefore, the utility model has following beneficial effect: (1) prevents the vibrations of gas pressure bottom flange, reduces noise; (2) simplify technique, process more convenient; (3) prevent valve gap from rotating, reduce further noise.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model;
In figure, push rod 1, rocking arm 2, pressing plate 201, pressing plate projection 202, restraining groove 203, valve gap 3, valve gap projection 301, bearing pin 302, gap 4, spacing shim 5, elastic collar 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1 and Figure 2, a kind of turbocharger deflation valve lid, comprise push rod 1, valve gap 3 and be arranged at the rocking arm 2 of push rod end, described rocking arm is provided with the pressing plate 201 relative with valve gap, pressing plate is provided with through hole, valve gap top is provided with the bearing pin 302 running through through hole, and bearing pin is socketed with spacing shim 5 through the end winding support of through hole, adopts to rivet and locate between bearing pin top and spacing shim.Bearing pin is socketed with the elastic collar 6 of fitting with clamp surface, pressing plate and valve gap are plane contact, and spring collar and pressing plate are plane contact.The periphery of pressing plate is provided with two pressing plate projections 202, restraining groove 203 is formed between two pressing plate projections, valve gap periphery is provided with a valve gap projection 301, in the protruding restraining groove 203 between two pressing plate projections of valve gap, gap 4 is provided with between the inner side surface of restraining groove and corresponding valve gap projection, this gap is 0.5 ~ 2mm, and in the present embodiment, this gap is 1.2mm.Elastic collar is bowl-type, and the large Transverse plane of elastic collar and valve gap are close to, and the little Transverse plane of elastic collar and spacing shim are close to, and the small end of elastic collar and the axial clearance of pressing plate are 0.3 ~ 1.5mm, and in the present embodiment, this axial clearance is 0.9mm.
In actual moving process, valve gap is by the mating reaction of valve gap projection with pressing plate upper limit position groove, thus keep relative with pressing plate fixing, thus prevent valve gap from rotating and producing noise, simultaneously owing to being subject to spacing shim effect, pressing plate and elastic collar are fitted tightly, under inhibit high-speed pneumatic effect, valve gap is stressed and acutely swing the noise of generation, and car load NVH performance is improved.
