Abstract
The utility model relates to the constructional arrangement of an engine body, in particular to a reinforcing rib of a bolt hole lug for an engine body. The reinforcing rib is combined with water channel sand removal holes at the two sides of the engine body together; the upper part of the reinforcing rib is provided with a single rib to be connected with the bolt hole lug of the engine body and a side wall; and the single rib is divided into two ribs at the position of the water channel sand removal hole, and extends downwards to a diaphragm plate arranged on the bottom of the water channel of the engine body, and the ribs are communicated with the bolt hole lug of a main bearing cover. The arrangement of the reinforcing rib is symmetrical to a clapboard plane between two cylinders and the water channel sand removal hole. In the utility model, the structure and the arrangement of the reinforcing rib of the bolt hole lug for the engine body are improved, thus improving the rigidity of the engine body and improving the sand removal of the middle water channel.
Description
Technical field
The utility model relates to the engine body structural configuration, relates in particular to engine body bolt hole lug stiffening rib.
Background technique
Motor as herein described is meant the four-stroke vehicle high speed diesel engine, and engine body is meant dry-sleeved four-stroke vehicle high speed diesel engine body.This body six bolts of every cylinder that adopt fix cylinder head more, wherein in the dividing plate plane that two are arranged between two cylinders, in the middle of the dividing plate long and narrow water channel are arranged, in order to guarantee the cooling of this place's cylinder barrel.Described body bolt hole lug is exactly specially that finger is this to be arranged in the body water channel between two cylinders in the dividing plate plane, the bolt hole lug that is used for fixing cylinder head bolt, for 4 cylinder diesels, this bolt hole lug is distributed in body 1 cylinder and 2 cylinders, between 2 cylinders and 3 cylinders and 3 cylinders and 4 cylinders, have 6, by formula (4-1) * 2=6 calculates; For 6 cylinder diesels, this bolt hole lug number is (6-1) * 2=10.The bolt hole lug must link to each other with organism sidewall with the rib of certain altitude and width, transmits power to bear bolt, and rib preferably extends to body water channel bottom transverse dividing plate place, and connects with bolt of main bearing cap hole lug.Bolt hole lug stiffening rib promptly refers to connecting bolt hole lug and organism sidewall, bears the rib that bolt transmits power.
The cylinder core distance of modern vehicle high speed diesel engine body is very little, the about 5mm of minimum channel width between two cylinders.When body adopted casting, the sand removal of this part water channel should be paid attention to especially, if water channel stops up or be obstructed, then can cause local superheating, caused cylinder sleeve, piston irregular wear, can produce scuffing of cylinder bore when serious.Generally be provided with water channel sand removal hole in the both sides of body, in order to guarantee sand removal for this reason.In the same plane, the sand removal hole also preferably is arranged in this plane, so the layout of bolt hole lug stiffening rib must be avoided the sand removal hole because water channel between two cylinders and body bolt hole lug are everlasting.Existing body bolt hole lug stiffening rib is arranged as Fig. 1 to shown in Figure 6, especially as can be seen from the sectional view of Fig. 3, Fig. 5, the stiffening rib 41 of valve tappet side is the diagonal bar of two symmetric arrangement, only extend to the top in sand removal hole 61, the bottom in sand removal hole 61 does not have stiffening rib, and is unfavorable to body rigidity; Though the stiffening rib 42 of fitting machine oil cooler side links up with the water channel diaphragm 3 of bottom and Main bearing bolt hole lug, helps improving body rigidity, the position (referring to Fig. 4) of stiffening rib 42 have to be avoided in sand removal hole 62, makes the sand removal of internal water main 1 relatively more difficult.
The model utility content
The purpose of this utility model is to provide a kind of engine body bolt hole lug stiffening rib, and this stiffening rib had both improved the rigidity of engine body, had improved the sand removal of internal water main again.
The utility model is achieved in that a kind of engine body bolt hole lug stiffening rib, described stiffening rib and water channel sand removal hole, body both sides combine, the top of described stiffening rib is a single reinforcement, link to each other with sidewall with body bolt hole lug, be divided into two at water channel sand removal hole place and become two muscle, and extend downward the diaphragm place of body water channel bottom, connect with bolt of main bearing cap hole lug.
Dividing plate plane between the layout of described stiffening rib and two cylinders and water channel sand removal hole symmetry.
Described body is circular by the water channel sand removal hole of valve tappet side.
The water channel sand removal hole of described body fitting machine oil cooler side is long-round-shape or circle.
The utility model had both improved the rigidity of engine body by improving the structure and the layout of body bolt hole lug stiffening rib, had improved the sand removal of internal water main again.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 7 to Figure 12, especially Fig. 9 and Figure 11.A kind of engine body bolt hole lug stiffening rib, described stiffening rib 8 are meant and connect this bolt hole lug 5 and organism sidewall, bear the rib that cylinder head bolt transmits power.Described stiffening rib 8 combines with water channel sand removal hole, body both sides 6, the top of this stiffening rib 8 is a single reinforcement, link to each other with sidewall with body bolt hole lug 5, be divided into two at 6 places, water channel sand removal hole and become two muscle, referring to Fig. 9 a and Fig. 9 b, and extend downward diaphragm 3 places of body water channel bottom, connect with bolt of main bearing cap hole lug.
Dividing plate 7 planes between the layout of described stiffening rib 8 and two cylinders and water channel sand removal hole 6 symmetries, and the internal water main between two cylinders 1 and body bolt hole lug 5 and sand removal hole 6 are all in same plane.
Described body be circular by the water channel sand removal hole 61 of valve tappet side, must be with silently this hole being blocked after finishing body and processing, mix with machine oil to prevent cooling water in the body crankcase that bleeds.
The water channel sand removal hole 62 of described body fitting machine oil cooler side is long-round-shape or circle, links to each other to improve body rigidity with stiffening rib 82 with the body outer wall along the vertical direction.Because this side of body is equipped with machine oil cooler, sand removal hole 62 can be used as the waterway of machine oil cooler.
The structure of body bolt hole lug stiffening rib of the present utility model and layout had both improved the rigidity of body, had improved the sand removal of internal water main again.
