Description
Technical field
The present invention relates to turbo-charger technical field, a kind of specifically pressure booster with variable cross section nozzle ring.
Background technology
Turbocharging is one of the developing direction of world's internal-combustion engine technology, is the main approach that current internal combustion engine is strengthened,
Turbocharging technology can increase substantially engine output, energy saving, reduce engine exhaust pollution.And variable cross section
Booster nozzle ring is the critical component in current advanced variable geometry turbocharger, is used for engine supercharger before and sprays
The blade angle of mouth ring is fixed, blade is non-adjustable, and booster can only make engine in some power interval efficient operation, I am public
Department takes the lead in booster nozzle ring structure being improved to adjustable blade burner at home, and blade drives with shift fork soldering member by drive disk
Rotation to change blade angle, adjust flow area, make engine under the support of booster each power section can be compared with
Efficiently work.
The Chinese patent of Patent No. 201120544236.3 discloses a kind of pressure booster with variable cross section nozzle ring, in its skill
In art scheme, pin be fixed on shifting disc, shift fork is sleeved on pin, and the tail portion of blade is connected with shift fork, in this way, work as shifting disc by
When external force rotates, pin will drive shift fork to rotate, and then band movable vane piece rotates shift fork, be cut with changing blade angle, adjusting air-flow
Face will produce opposite sliding when pin drives shift fork rotation between pin and shift fork, and sell and contacted for line between shift fork, contact
Area is smaller, in this way, in opposite sliding, pin and shift fork are easier to be worn, after pin and shift fork abrasion are larger, it will so that
The contact position of pin and shift fork deforms, it will so that pin and shift fork can not be normally driven between the two, makes the nozzle ring capable of changing cross sections
Can not normal use, bring security risk；In addition, in its technical solution, shifting disc is placed on mounting disc and spacer pin is constituted
Restriction space in, and spacer pin needs to be pushed down with the spiral case of turbocharger to be positioned, and between spiral case and spacer pin
There are certain gaps to be easy to cause the axial float of spacer pin when turbocharger high temperature and high speed works, it will so that dialling
Moving plate shifts, it will so that shift fork is detached from shifting disc, the booster nozzle ring can thus be made to can not work normally.
