Description
Technical field
The utility model relates to variable intake manifold technical field, particularly relates to the universal wear-resisting rotatingshaft of a kind of variable intake manifold.
Background technique
Along with market energy-saving and emission-reduction requirement, multiple energy conservation standard selected by motor, up-to-date Introduced From Abroad new technique, and wherein have variable intake manifold, variable intake manifold divides: 1. drum type; 2. split type valve sheet type; 3. integrated valve flap-type.Drum type intake manifold requires macrostructure, large volume chamber, comparatively multiple component composition, product weight is comparatively large, and cost is high, and quality of fit requires high, otherwise larger noise will be produced during engine running, production technology window is little minimum. and split type complex structure scrappage is higher, and comparatively multiple component composition manufacturing efficiency is low, and matching gap is large, larger noise is produced after motor operates for a long time, coupling shaft straightness accuracy requires high, dependence on import always, high cost; Integrated valve flap-type structure simple production efficiency is high, and defect integrated structural rigidity requires high, easily stuck, easy to wear.Produce larger noise after motor operates for a long time, coupling shaft straightness accuracy requires high, and scrappage is large.
Model utility content
The purpose of this utility model is to provide a kind of variable intake manifold universal wear-resisting rotatingshaft, integrated valve flap-type (universal wear-resisting rotatingshaft) overcomes stuck, wearing and tearing, the problems such as reducing coupling shaft straightness accuracy requires cost-saving, the noise that solving weares and teares after motor operates for a long time brings.
To achieve these goals, the utility model adopts following technological scheme:
The universal wear-resisting rotatingshaft of a kind of variable intake manifold, include valve block main shaft, rotate ball cover, roating sphere and crank, described valve block main shaft end is square body, described roating sphere is provided with the square hole matched with described valve block main shaft end, described rotation ball cover is upper semi-circle ball cover and lower semi-circle ball cover, roating sphere interference is wrapped up by described upper semi-circle ball cover and lower semi-circle ball cover, and described rotation ball cover is by upper semi-circle ball cover with lower semi-circle ball cover is closed is fixed on crank.
Described upper semi-circle ball cover and lower semi-circle ball cover one end are connected through the hinge, and the described upper semi-circle ball cover the other end is provided with a pair hole clipping; The described lower semi-circle ball cover the other end is provided with a pair card stake, matches with a pair hole clipping of described upper semi-circle ball cover.
The beneficial effects of the utility model:
Valve block assembly inserts requirement in valve block housing with type and can rotate by an angle of 90 degrees, loads joint coupling and valve block housing interference fit, inserts crank assemblies and valve block assembly interference fit, overcome stuck, wearing and tearing, reduce coupling shaft straightness accuracy and require cost-saving.
