Abstract
The utility model relates to a camshaft structure of an automobile engine. The camshaft structure of the automobile engine comprises a shaft lever, a set of journals arranged on the shaft lever, and a center main oil channel arranged along the shaft lever in the axial direction, wherein an oil groove connected with a main oil channel of a cylinder cover is formed in the intermediate journal, and an oil hole is formed between the oil groove and the center main oil channel. When the engine is started, lubricating oil can enter the journals at the ends of the camshaft at the highest speed to lubricate the journals, abrasion to the journals is reduced, and the service life of the camshaft is prolonged.
Description
Technical field
The utility model relates to a kind of camshaft of car engine structure, relates in particular to a kind of oil line arrangement structure of engine cam.
Background technique
Along with the speed up of internal combustion (IC) Engine Design, the requirement of motor at aspects such as performance output, reliability, NVH is harsher strict.When engine start, because lubrication system oil circuit is longer, in addition traditional lubrication system oil cake arrange design is generally to least significant end axle journal, to pass through successively oil-way lubrication from camshaft main journal, it is lubricated poor that thereby the oil pressure at this kind of design least significant end axle journal place causes compared with the low fuel pressure of main journal, weares and teares large compared with other axle journals.
Model utility content
The purpose of this utility model is to provide a kind of camshaft of car engine structure, the axle journal that solves available engine camshaft oil circuit end when engine start fuel feeding not in time, problem easy to wear.
The utility model solves the technological scheme that its technical problem adopts: a kind of camshaft of car engine structure, comprise axostylus axostyle, be arranged on one group of axle journal on axostylus axostyle, along the axial arranged center main oil duct of axostylus axostyle, on intermediate journal, be provided with the oil groove being connected with cylinder cap main oil gallery, between oil groove and center main oil duct, be provided with oilhole.
For making the lubricant oil in oil groove enter fast center main oil duct, described oilhole is circumferentially evenly distributed with 4 along oil groove.
For convenience of processing, described center main oil duct runs through whole axostylus axostyle; One end of axostylus axostyle is provided with the steel ball sealing, and the other end is provided with the bolt sealing.
The beneficial effects of the utility model: the oil groove being connected with cylinder cap main oil gallery is arranged on intermediate journal, lubricant oil is from intermediate journal enters center main oil duct, axle journal to both sides flows, reduce the time that lubricant oil flows to end axle journal, can be in the building-up time that fully guarantees each axle journal lubricating oil pressure of overall balance under the lubricated prerequisite of camshaft bearing journal, thereby the journal wear while effectively improving engine start, particularly for the distal-most end axle journal compared with long camshaft, improve effect more obvious, improve the whole service life of camshaft.Described oilhole arranges 4, can make the lubricant oil in oil groove enter fast center main oil duct.Described center main oil duct is designed to run through the through-hole form of whole axostylus axostyle, and what make is easy to process, saves processing cost.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view at the utility model oil groove place.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of camshaft of car engine structure, comprises axostylus axostyle 1, is arranged on one group of axle journal 2 on axostylus axostyle 1, comprises main journal 21, the first axle journal 22, the second axle journal 23, the 3rd axle journal 24, the 4th axle journal 25.Along the axial arranged center main oil duct 3 of axostylus axostyle 1, described center main oil duct 3 runs through whole axostylus axostyle 1.One end of axostylus axostyle 1 seals by steel ball press-loading 7, and the other end bolt 8 used when connecting timing gear and camshaft is tightened sealing.
Be positioned on the middle axle journal 23 of axostylus axostyle 1 and be provided with the oil groove 5 being connected with cylinder cap main oil gallery 4,3 of oil groove 5 and center main oil ducts are provided with oilhole 6.Described oilhole 6 is circumferentially evenly distributed with 4 along oil groove 5.Lubricant oil is from intermediate journal 23 enters center main oil duct 3, axle journal 2 to both sides flows, reduce the time that lubricant oil flows to end axle journal 2, can be in the building-up time that fully guarantees each axle journal 2 lubricating oil pressures of overall balance under the lubricated prerequisite of camshaft bearing journal 2, thereby 2 wearing and tearing of the axle journal while effectively improving engine start, particularly, for the distal-most end axle journal 2 compared with long camshaft, improve effect more obvious.
Described axle journal number is not limited to 5; such as for six cylinder engine, its camshaft has 7 axle journals, when as long as oil groove is arranged on to intermediate journal place; be that cylinder cap lubricant oil enters central oil passage from intermediate journal, all belong to protection domain of the present utility model.
