Abstract
The invention discloses a lower cylinder body of an automobile engine, comprising an installing surface of a back end flywheel shell, a left side surface, a right side surface, a combining surface of an upper cylinder body, a combining surface of an oil bottom shell and an installing surface of a front cover, wherein the installing surface of the front cover extends out of the front end of the lower cylinder body; a timing chain wheel is positioned in the extending position so that the installing surface of the front cover of the cylinder body and the front cover form one-dimension sealing in assembly process; and the combining surface of the oil bottom shell and the oil bottom shell form the one-dimension sealing in a whole engine state. The design of the lower cylinder body of the engine is completely suitable for die-casting process of high speed and high efficiency and meets the requirement of the quick development of automobile industry; the lower cylinder body solves the supply bottleneck of key parts and components, solves the problems (such as timing and phase position) of regulation, replacement and the like of the inner part of the engine and reduces the trouble of disassembling relative parts of the engine and potential risks such as leakage and the like.
Description
Technical field
The invention belongs to technical field of automobile engine, specifically, relate to a kind of novel lower cylinder body of engine for automobile.
Background technique
Development of automobile has over one hundred year history to today, and engine technology is also ripe day by day, toward more high-end development! New technology is constantly used.Timing system, chain-driven rely on its transmission efficiency, high reliability, and with advantage such as motor equal working life, in engine art, the increasing employing.Chain-driven generally is arranged in motor head, and so the outside of cylinder body is in chaindriven peripheral seal, become a problem demanding prompt solution, before the traditional lower cylinder body of engine, first main bearing seat is opening, forms lower cylinder body, oil sump, the sealing of three parts T of front cover font thus.And more other two parts of front cover, dismounting is more frequent! Simple from casting, processing, simple with assembling, reliably on the contradiction, need the lower cylinder body of a new form to solve this problem.
Summary of the invention
The problem to be solved in the present invention is that the motor car engine lower cylinder body in rough-cast, course of working, makes every effort to simple, is easy to realize; And in the assembly process, simple, reliable, reduce or avoid potential quality risk, and in the later stage engine components maintenance process, convenient disassembly.
In order to address the above problem, the invention discloses a kind of lower cylinder body of engine for automobile, comprise: rear end flywheel casing attachment face, the and arranged on left and right sides face, upper cylinder body junction plane, and oil sump junction plane, also comprise the front cover attachment face, this front cover attachment face stretches out at the front end of lower cylinder body, and timing sprocket is positioned within the extending area, makes cylinder body front cover attachment face form the one dimension sealing with front cover in assembly process; Described oil sump mating face forms the one dimension sealing with oil sump under motor complete machine state.
Further, at the back of lower cylinder body main bearing seat, offer the loss of weight groove; On main bearing seat bolt hole axis, be furnished with machine oil dividing plate installation base; Be furnished with the loss of weight spill port in the main bearing seat both sides; Be furnished with stiffening rib at lower cylinder body and arranged on left and right sides face.
Further, described lower cylinder body is the die casting aluminium cylinder body, and dynamic model is opened to oil sump junction plane 8 directions, reduces the unnecessary machining allowance of foundry goods.
Lower cylinder body structure of the present invention, by stretch out one section front cover mating face at front end, lower cylinder body is combined with oil sump, lower cylinder body combines with the front end cover cap, each self-forming one dimension sealing, the dismounting mutual noninterference, this lower cylinder body accomplishes to be easy to die casting under the situation of the needs that take into full account casting, processing, assembling; Satisfying under the requirement of strength, alleviate casting quality as far as possible; Reduce machining allowance unnecessary, that form because of mold releasability; Aspect assembling and later engine maintenance, avoid the related dismounting of adjacent elements.
This pattern lower cylinder body of engine, design are suitable for fast pace, high efficiency extrusion process fully, satisfy the automobile industry develop rapidly, the supply bottleneck of key components and parts; Having solved simultaneously because of engine interior needs problems (such as timing, phase place) such as adjustment, replacing, reduces the trouble of dismounting motor correlated parts, has reduced potential risks such as leakage simultaneously.

Embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As Fig. 1, Fig. 2 and shown in Figure 3, lower cylinder body of engine for automobile comprises: front cover attachment face 5, rear end flywheel casing attachment face, and the and arranged on left and right sides face, upper cylinder body junction plane 2, oil sump junction plane 8, wherein front cover attachment face 5 stretches out at the front end of lower cylinder body.Timing sprocket is positioned within the extending area.Cylinder body front cover attachment face 5 forms the one dimension sealing with front cover in assembly process, promptly cylinder body front cover attachment face 5 seals in the mode that compresses with the attachment face of front cover, and sealing surface is a plane.Oil sump mating face 8 also forms the one dimension sealing with oil sump under motor complete machine state.This lower cylinder body is the die casting aluminium cylinder body, and dynamic model is opened to oil sump junction plane 8 directions, reduces the unnecessary machining allowance of foundry goods; At lower cylinder body main bearing seat back, under proof strength requires, offer loss of weight groove 6, to optimize casting quality; Machine oil dividing plate installation base 7 is arranged in the bolt hole axis that main bearing seat is used to install main bearing cap, simplifies extrusion process; Main bearing seat is inlaid with cast iron and inserts 3; The main bearing seat both sides are furnished with loss of weight spill port 4, take into account lower cylinder body loss of weight, two functions of oil return; It highly is 15mm that lower cylinder body and arranged on left and right sides face is arranged, thickness is the stiffening rib 1 of 4mm, to reduce vibrating noise.
