Abstract
The utility model relates to a novel camshaft front end cover of an engine with a variable valve timing system. Four camshaft front end cover fixing bosses are arranged in the middle and on two sides of the front end cover, and an OCV (oil control valve) oil inlet hole and four oil outlet holes are arranged on two symmetrically distributed cases. The novel camshaft front end cover is compact in structure, reasonable in design and convenient in mounting, cylinder cover space is saved, design difficulty of lubricating oil ways is reduced, a motor is more compact in structure and more convenient in mounting, and production cost and utilization cost can be reduced.
Description
Technical field
The utility model relates to a kind of camshaft front cover, in particular for a kind of novel changable valve timing system engine cam front cover.
Background technique
At present, camshaft is the vitals of two VVT motors, and camshaft-bearing cap places camshaft top and camshaft to adopt Spielpassung, prevents circular runout and the axial motion of camshaft in running.Engine camshaft bearing cap in the past only plays the positioning cam axle, prevents the effect that it is in operation and beats.Because the oil circuit in two VVT motors is very complicated, this traditional front cover is difficult to meet the demands, and the lubricant oil of complete machine is arranged produce bigger puzzlement.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and is easy for installation, reduced lubricating oil path simultaneously and arranged a kind of novel changable valve timing system engine cam front cover of difficulty.
In order to achieve the above object, the technical solution adopted in the utility model is: the middle part of front end lid and both sides are provided with four camshaft front cover fixing lug boss, have OCV oil inlet hole and OCV oil outlet on two casings of symmetrical distribution.
The utility model has the advantages that:
Compact structure, reasonable in design, easy for installation, saved the cylinder cap space, reduced the design difficulty of lubricating oil path, the structure that makes motor is compact more, installs more conveniently, reduces production costs and user cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a 3 D stereo schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the middle part of the utility model front end lid 4 and both sides are provided with four camshaft front cover fixing lug boss 1, have OCV oil inlet hole 2 and OCV oil outlet on two casings of symmetrical distribution.
The bottom of described OCV oil inlet hole 2 and OCV oil outlet 3 all has groove.
Described OCV oil inlet hole 2 and OCV oil outlet 3 all are counterbores.
The utility model has camshaft front cover fixing lug boss 1 on front end lid 4, camshaft front cover fixing lug boss 1 is fixed on engine cylinder by bolt with front end lid 4 and covers, and plays the effect of positioning cam axle.The lubricant oil that comes from cylinder cap enters front end lid 4 arrival OCV valves by OCV oil inlet hole 2, is got back to the chamber and the delay chamber in advance of cam phaser by OCV oil outlet 3.Thereby play inlet and outlet camshaft front cover and OCV oil circuit integrated, the effect of simplified structure.
