Abstract
The utility model provides a rear cover plate assembly for a diesel engine. The rear cover plate assembly for a diesel engine is mainly composed of a rear cover plate, an engine oil filter, an engine oil pressure indicator and an engine oil pressure regulator. The engine oil pressure indicator is arranged at the top end of a cover of the engine oil filter. The engine oil filter is arranged at the middle part of the rear cover plate. A casing of the engine oil filter and the rear cover plate are integral. A separation angle of the shaft center line of the casing of the engine oil filter and a mounting surface of the rear cover plate is equal to 0-90 DEG. The rear cover plate and the engine oil filter are integrally combined by the utility model, and the utility model has the advantages of compact structure, simple appearance, beautiful appearance, and good integral performance. The intensity of the rear cover plate is enhanced. The service life is extended.
Description
The utility model relates to a kind of diesel engine part, particularly a kind of back shroud assembly of single-cylinder horizontal cylinder of diesel engine.
The back shroud of single-cylinder horizontal diesel engine only has the effect of sealing the body back door merely at present, and does not have the effect of filtering machine oil.For filtering machine oil, be at the outer then other fitting machine oil rectifier of back shroud.The whole parallel suspend of oil filter is in the outside of back shroud, and by screw on back shroud.This structure, integrity is poor, and profile is messy, and the contour length of complete machine is longer, and diesel engine very easily breaks filter cleaner in transportation process.Because filter cleaner is to be connected on outward on the back shroud by screw, has weakened the intensity of back shroud.
It is the diesel engine back shroud assembly of one that the purpose of this utility model provides a kind of compact structure, appearance oil filter and diesel engine back shroud.
The technical solution of the utility model is mainly to be made up of back shroud, oil filter, engine oil pressure indicator and engine oil pressure regulator.The engine oil pressure indicator is arranged at the top of oil filter lid, and oil filter is arranged on the middle part of back shroud, as a whole of the housing of oil filter and back shroud, and the angle of the shaft axis of oil filter body and back shroud attachment face is the 0-90 degree.
Back shroud is provided with oil inlet hole and oil outlet; Be provided with the side in the oil filter lid and put oil duct, the side is put oil duct one end and is communicated with the filter cleaner inner chamber, and the other end communicates with oil outlet; Also be provided with the engine oil pressure regulator that interlinks with the filter cleaner inner chamber on the back shroud.
Back shroud is made for the die casting aluminium material.
The utility model has the advantages that back shroud and oil filter are integrated, compact structure, profile is succinct, and is elegant in appearance, and overall performance is good, has reduced the installation dimension of filter cleaner and back shroud to greatest extent.Because both are integrated, and no longer include installation junction plane between the two, have reduced the link of one leakage of oil, also omitted the mounting hole of the oil filter on the back shroud simultaneously, strengthened back shroud intensity greatly.After being integrated, because in the cylinder block at the recessed back shroud of filter cleaner inner chamber middle part, the length of its exposed parts significantly reduces, thereby the chance that diesel engine is broken mutually in transportation process significantly reduces, for enterprise has reduced loss.Just can exchange filter core easily for as long as the utility model is pulled down the filter cleaner lid, can not cause the machine oil waste.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing of Fig. 1;
Fig. 3 is the M-M rotation direction sectional drawing of the strainer cover subdivision of Fig. 1;
Fig. 4 is the part schematic representation of back shroud 17.
Below in conjunction with accompanying drawing the utility model and embodiment are described in further detail:
The utility model mainly is made up of back shroud, oil filter, engine oil pressure indicator and engine oil pressure regulator.The middle part of back shroud 17 is provided with a cavity F who concaves, and its cavity partly is the housing of oil filter, and the angle α of the attachment face of the shaft axis of cavity F and back shroud 17 is the 30-45 degree, and cavity F and back shroud 17 are holistic aluminum casting.The right edge of back shroud 17 is provided with oil inlet hole A, and the limit, left side is provided with oil outlet B.The lower end of oil outlet B is provided with the screw E of fitting machine oil pressure regulator, and screw E communicates with filter cleaner inner chamber (cavity) F on the back shroud 17.Oil inlet hole A communicates with cavity F.Technology plug 1 is equipped with in the outside of oil inlet hole A and oil outlet B respectively.The hydraulic fluid port of oil inlet hole A and oil outlet B all is arranged on the attachment face of back shroud 17 respectively.Back shroud 17 is made for the die casting aluminium material.
Oil filter contains stud bolt 12, filter core 18, bracket 11, spring 13, pallet 14, seal ring 15,16, filter cleaner lid 22, O shape circle 21 and tightening nut 20.Tightening nut 20 is a logical heart nut, is arranged on the central authorities of filter cleaner lid 22, by tightening nut 20 tension stud bolts 12, thereby lid 22 is pressed on the back shroud 17.The other end of tightening nut 20 exposes outside the lid 22, and this end is provided with internal thread, and engine oil pressure indicator 19 is installed in the top of filter cleaner lid 22 by this screw thread.
Be provided with the side in the filter cleaner lid 22 and put oil duct D, the end that oil duct D is put on the side communicates with the filter cleaner inner chamber, and the other end communicates with oil outlet B.Also be provided with relief valve on the filter cleaner lid 22, relief valve one end communicates with oil inlet hole A, and the other end communicates with the filter cleaner inner chamber by oil duct C.Relief valve contains spring 10, nut 9, steel ball 24 and plug 23.Put oil duct D place on the side between filter cleaner lid 22 and the back shroud 17 and be provided with oily locating stud 7 of hollow mistake and seal ring 8.Be provided with the engine oil pressure regulator among the screw E of back shroud 17.The engine oil pressure regulator contains pressure adjusting spring 2, fastening screw nut 3, helmet 4, screw press 5 and steel ball 6, and the engine oil pressure regulator links with back shroud 17 by its screw press 5 and fastening screw nut 3.By regulating the pressure of screw press 5 can regulate filter cleaner inner engine oils.
During the diesel engine running, machine oil from diesel engine oil pan by entering the oil inlet hole A of back shroud 17 right lower sides after one primary oil filter and the oil pump, enter oil filter inner chamber F through back shroud 17, gap after filter core 18 filters between the mounting hole of tightening nut 20 and filter cleaner lid 22 flows into the oil duct C the lid 22, passed through the oil outlet B that oily locating stud 7 enters back shroud 17 upper left sides again, and then machine oil was sent in the diesel engine cylinder block.Wherein, some machine oil enters into tightening nut inside by the oilhole on the tightening nut 20, thereby enters into engine oil pressure indicator 19, impels the work of engine oil pressure indicator, demonstrates current engine oil pressure.Being installed in the relief valve on the filter cleaner lid, is when guaranteeing diesel engine starting or filter element part 18 when stopping up, and guarantees that organic oil supplies with diesel engine.
