Abstract
The utility model discloses an automobile engine cylinder body, a cylinder hole (1), a water jacket hole (2) and a cylinder cover faying surface (3) are arranged on the cylinder body. The water jacket hole (2) is arranged at a cycle of an outer wall of the cylinder hole (1) in a way of passing, the cylinder holes (1) are arranged in parallel, ex-circle faying surfaces of two cylinder holes (1) form an included angle. The cylinder cover faying surface (3) is depressed inwards into the included angle to form a cylinder cover screw lug (4), a bolt hole (5) is opened on the cylinder cover screw lug (4), connecting ribs are arranged at two sides of the cylinder cover screw lug (4) and an outer wall of the cylinder hole (1). The structure of the utility model is simple, the strength of the cylinder cover screw lug can be increased, thereby the rigidity of a cylinder barrel can be improved, at the same time of increasing the strength of a cylinder cover bolt hole, the casting manufacturability of the cylinder body is also optimized.
Description
Technical field
The utility model belongs to technical field of automobile engine, relates to a kind of automobile engine cylinder-body concretely.
Background technique
The housing assembly of motor car engine is the skeleton of motor, and all major parts and the annex of motor is installed, and bears the various load in the motion.There are cylinder hole, oil duct and water channel in its inside, and it mainly acts on is to realize lubricated and cooling.The housing assembly of motor mainly is made up of cylinder body, cylinder or cylinder sleeve, cylinder cap, cylinder liner and oil sump etc.Wherein, cylinder body is cast by gray cast iron or aluminum alloy, and cylinder is arranged at its top, and crankshaft support hole and crankcase are arranged at the bottom.。
Cylinder bolt lug and cylinder hole outer wall on this motor upper cylinder cover junction plane is not connected as a single entity in the market, but independent casting forms, such result one is casting difficulty and the cleaning cost that has increased cylinder body, simultaneously owing to cylinder bolt lug intensity difference, cylinder barrel poor rigidity, in engine working process, faults such as the scuffing of cylinder bore that is prone to cylinder bolt lug place's crackle and causes because of cylinder barrel distortion, burn oil.
The model utility content
Thereby the purpose of this utility model is to provide a kind of cylinder bolt lug intensity that can improve to improve the cylinder barrel rigidity, when improving the cylinder bolt hole strength, optimized the automobile engine cylinder-body of the casting manufacturability of cylinder body again.
The technical solution of the utility model is as follows:
A kind of automobile engine cylinder-body, this cylinder body is provided with cylinder hole, water jacket hole, cylinder cap mating face, one week of outer wall that is arranged in described cylinder hole that described water jacket hole connects, described cylinder hole is arranged side by side, the cylindrical mating face in two cylinder holes forms angle, described cylinder cap mating face is recessed and forms cylinder cap screw lug in the described angle, has bolt hole on this cylinder cap screw lug, and the both sides of described cylinder cap screw lug and described cylinder hole outer wall are provided with connecting tendon.
The degree of depth that is shorter in length than described water jacket hole of described connecting tendon.
The cylinder cap screw lug of will be on the cylinder cap junction plane thick individualism of cylinder hole wall relatively changes into cylinder hole outer wall by the mode that increases connecting tendon and fusing, when improving the cylinder barrel rigidity, improving cylinder cap screw intensity, avoided again when Foundry Production, the formation of weakness iron burnt-in sand in the cylinder body water jacket hole, guarantee the turbidity test in water jacket hole, optimized the casting manufacturability of cylinder body.
Beneficial effect: the utility model is simple in structure, improves the cylinder barrel rigidity, when improving the cylinder bolt hole strength, has optimized the casting manufacturability of cylinder body again thereby can improve cylinder bolt lug intensity.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a stereogram of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, 2: a kind of automobile engine cylinder-body, this cylinder body is provided with cylinder hole 1, water jacket hole 2, cylinder cap mating face 3, one week of outer wall that is arranged in described cylinder hole 1 that described water jacket hole 2 connects, described cylinder hole 1 is arranged side by side, the cylindrical mating face in two cylinder holes 1 forms angle, described cylinder cap mating face 3 is recessed and forms cylinder cap screw lug 4 in the described angle, have bolt hole 5 on this cylinder cap screw lug 4, the both sides of described cylinder cap screw lug 4 and described cylinder hole 1 outer wall are provided with connecting tendon 6.The degree of depth that is shorter in length than described water jacket hole 2 of described connecting tendon 6.
Claims (2)
1. automobile engine cylinder-body, this cylinder body is provided with cylinder hole (1), water jacket hole (2), cylinder cap mating face (3), one week of outer wall that is arranged in described cylinder hole (1) that described water jacket hole (2) connects, described cylinder hole (1) is arranged side by side, the cylindrical mating face in two cylinder holes (1) forms angle, described cylinder cap mating face (3) is recessed and forms cylinder cap screw lug (4) in the described angle, have bolt hole (5) on this cylinder cap screw lug (4), it is characterized in that: the both sides of described cylinder cap screw lug (4) and described cylinder hole (1) outer wall are provided with connecting tendon (6).
2. a kind of automobile engine cylinder-body according to claim 1 is characterized in that: the degree of depth that is shorter in length than described water jacket hole (2) of described connecting tendon (6).
