Abstract
The invention discloses a V-shaped diesel engine body which used two air cylinders which are arranged in a V shape. Furthermore, main oil holes are distributed on a box cover matched with the engine body instead of the engine body, more parts can be arranged in an included angle of the V-shaped air cylinder and at the lower portions of the outer sides of the V-shaped air cylinders, and accordingly the V-shaped diesel engine body is compact in the whole structure, attractive in appearance and small in size. The engine body is made of aluminum alloy die-casted parts, radiation fins are also formed in a die-casted mode, and accordingly the engine body is suitable for large scale production, light in the whole weight and attractive in appearance. Furthermore, air cooling is wholly utilized to cool, the radiation fins are arranged on the surfaces of the air cylinders, through venting grooves are formed by gaps between radiation fins, radiation can be achieved by air movement, a water interlayer structure can be completely removed, and accordingly the engine body is simple in manufacture process, light in weight, low in cost and free of water leakage. Aiming at the problem that traditional sealing hole are distributed to cause oil leakage, sealing holes are added on a front end face to reinforce the position where oil leakage are prone to happen to achieve the oil leakage prevention effect.
Description
Technical field
The invention belongs to field of power equipment technology, be specifically related to a kind of body of double-cylinder V-shape diesel engine.
Background technique
Engine body is the vitals in internal-combustion engine, and the strength and stiffness of body will directly affect the Performance And Reliability of motor.The intensity of body directly affects the working life of motor, and the rigidity of body will directly affect the noise and vibration performance of motor.At present, domestic V-type double cylinder wind cooling diesel makes cylinder block strength and rigidity can not get abundant guarantee in order to satisfy the light requirement of body weight, thereby makes the engine vibration noise larger.To the improving constantly of engine luggine Standard of Noise Measurement, for reaching the examination criteria needs, should take very large improvement measure to rigidity, the intensity of engine body for present country.Particularly the traditional approach of processing V-shaped double cylinder wind cooling diesel is pouring technology, if adopt cost extrusion process production lower, that efficient is higher greatly to reduce production costs, but need to make the architecture advances that adapts to Die Casting to body.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, compact, rationally, weight is light and handy, volume is little, external styling is attractive in appearance, is applicable to the V-type diesel engine body of Die Casting in enormous quantities.
for achieving the above object, technological scheme of the present invention is: the V-type diesel engine body, two cylinders that become V-type to arrange have been comprised, front-end face with the installation of V-type diesel engine case lid, cylinder-bore and hydraulic tappet hole have been arranged on the cylinder cap attachment face of described cylinder, hydraulic tappet hole is parallel with two cylinder-bore respectively, arranged the camshaft bearing hole on the center line of body inner chamber two cylinder V type angles, the main bearing hole that is arranged horizontally under the camshaft bearing hole, the through hole of actuating motor mounting hole and fastening use has been arranged in the left side of body, the surface of described cylinder is provided with radiating fin, gap between described radiating fin forms the ventilation slot that runs through, described front-end face is provided with closed hole, No. two closed holes that comprised a closed hole arranging perpendicular to hydraulic tappet hole, arranged perpendicular to cylinder-bore, and each cylinder place arranges three No. two closed holes at least.
When adopting technique scheme, adopt two cylinders to become V-type to arrange, and main oil-hole is not arranged on body, but be arranged in case lid that body coordinates on, can arrange more component with the cylinder in V-arrangement outer lower portion in the cylinder in V-arrangement angle, make compact overall structure, profile has attractive appearance, and volume is little.Because body adopts aluminum alloy die casting, radiating fin also integral die-cast is shaped, and is applicable to produce in enormous quantities, and total quality is light and handy, and external styling is attractive in appearance.And whole employing wind cooling temperature lowering, and be provided with radiating fin on the surface of cylinder, the gap between radiating fin forms the ventilation slot that runs through, can take full advantage of Air Flow and realize heat radiation, cast off the water interlayer structure of body once and for all, simplified manufacturing process, lightweight, cost is low, there is no seepy question.Owing to having increased closed hole on front-end face, arrange for traditional closed hole and easily produce the problem of leakage of oil, several position emphasis of leakage of oil that easily cause are reinforced, reach the effect of oil-leakage-prevention.
Further, the bottom inner and outer surface of body all is furnished with radiator shutter.This radiator shutter can increase the heat diffusion area of organism bottom oil groove, improves the effect of air cooling heat radiation.
Further, the other vent window that is provided with of actuating motor mounting hole.By vent window is set, changed the air flue structure of body, improved the effect of air cooling.
Further, the body inner chamber lower right that is positioned at main bearing hole is provided with the closed hole attachment post.Set up the closed hole attachment post, changed and to connect the present situation of sealing at the edge of front-end face, by sealing hole attachment post, can seal at the middle part of front-end face fasteningly, greatly increased whole sealability.
Further, the body internal surface be provided with the attachment post level be connected the stiffening rib that is connected.By setting up stiffening rib, increase the bulk strength of closed hole attachment post.
Further, the bottom outer surface of described body is established the mounting limit groove.The mounting limit groove is set can locate when mounted, places the problem that is difficult to install that causes because mounting hole can't accurately be located.
