Abstract
The utility model discloses a lifting lug mounted in a narrow space of an engine. The lifting lug mounted in the narrow space of the engine is characterized in that the lifting lug is arranged in a crevice between a cylinder cover and a water pump base plate. The two edges of the lifting lug are respectively provided with a mounting hole, and the lifting lug is fixed on an engine body through bolts. One contacting surface of the lifting lug is contacted with the cylinder cover and is not contacted with the water pump base plate, and another contacting surface of the lifting lug is machined, suspended step surfaces are arranged on the two sides of the lifting lug, and the suspended surfaces are provided with mounting holes. The lifting lug overcomes the defects that the contacting area of the bottom face of the lifting lug in the narrow space is small, and part of the bottom face is stressed greatly, and the reliability of the lifting lug is effectively improved through the supporting effect of other parts.
Description
Technical field
The utility model relates to motor security system field, particularly a kind of shackle structure of motor lifting usefulness.
Background technique
In order to lift motor, need front and back installation hanger on motor usually.Hanger is installed in the upper part of leaning on of cylinder block usually, and the small part motor is contained in hanger on the cylinder head.But cylinder head links together cylinder head and cylinder block by cylinder head bolt.Lift in cylinder head, might the connection tightness between cylinder head and the cylinder block be impacted, thereby cause poorly sealedly, this situation is particularly evident for the motor of a cylinder one lid.The unreliable meeting of sealing causes more serious fault between engine cylinder cap and the cylinder block.Be contained on the cylinder head for fear of hanger, people always install design to hanger on the cylinder block or on other component by every means, with this cause unfavorable: hanger design and installation complexity, it is attractive in appearance to influence machine shape, even because the space feature layout, at all can't be the hanger design on cylinder block; Part beyond cylinder block is arranged hanger, may cause the part strength deficiency to have potential safety hazard, maximum trouble then is, part before and after the cylinder block is close together by sealing mostly, utilize these parts that hanger is installed, make it to bear so big load, even part strength is enough, sealing surface stressed also might cause leakage of oil, leak.
In fact, in this case, be originally on the preceding hanger holding water pump backing plate that the water pump packing face probability that leaks is very high, and the motor of this case is a cylinder one lid structure, water leakage fault takes place in own cylinder head rigidity deficiency easily, also can't be contained in hanger on the cylinder head.Based on top institute alleged cause, the cylinder block end face that exposes in the crack of the utility model between cylinder head and water pump backing plate, the design hanger is contained on the cylinder block end face, utilizes the cylinder cap back rest supports, improve the intensity of hanger, successfully solve the Lug Design installation question.
Summary of the invention
The purpose of this utility model is to provide a kind of formula layout design hanger of " seizing every opportunity " in narrow space, for achieving the above object, according to the hanger that the utility model provides a kind of motor narrow space to install, the both sides design bolt mounting holes of hanger lifting position.Its core content is to utilize the supporting effect between the part to improve the easy for installation, rational in infrastructure of part Security, the hanger that safe and reliable a kind of motor narrow space is installed.
Technical solution of the present utility model is such, the hanger that a kind of motor narrow space is installed, it is characterized in that hanger (1) is contained in the crack between cylinder head (2) and the water pump backing plate (3), hanger (1) the both sides mounting hole that respectively distributes, hanger (1) is by being fixed by bolts on the engine body, a surface of contact (4) of hanger (1) contacts with cylinder cap (2), does not contact with water pump backing plate (3).
A surface of contact (4) processing of hanger (1).
There is unsettled step surface hanger (1) both sides, and unsettled step surface has mounting hole.
The utility model has the advantages that, because the slit location spatial altitude is big, bolt installed the shoulder back side make unsettledly, avoid the mounting hole drilling depth excessive, improve technology capability.The surface of contact of hanger and cylinder head is processed smoothly, is beneficial to cylinder head excellent support is provided.Rational in infrastructure, easy to use, safe and reliable.
Description of drawings
Fig. 1 is the schematic representation that the utility model motor narrow space is installed hanger.
The master that Fig. 2 installs hanger for the utility model motor narrow space looks sectional view.
Among Fig. 1～Fig. 2, hanger (1), cylinder head (2), water pump backing plate (3), surface of contact (4).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.，
The hanger that a kind of motor narrow space is installed is characterized in that hanger (1) is contained in the crack between cylinder head (2) and the water pump backing plate (3).Hanger (1) the both sides mounting hole that respectively distributes, hanger (1) is by being fixed by bolts on the engine body.A surface of contact (4) of hanger (1) contacts with cylinder cap (2), does not contact with water pump backing plate (3).A surface of contact (4) processing of hanger (1).There is unsettled step surface hanger (1) both sides, and unsettled step surface has mounting hole.
This hanger can be made with magnesium iron QT500 material or Common Straight Carbon Steel Q235-A, and the thickness of hanger is decided according to the width of crack, and this thickness need be more than the width 0.5mm less than crack, and the side that contacts with cylinder head needs machining.Bolt is installed surface of contact and is needed machining, guarantees that attachment face is smooth, and is parallel to the bottom surface of hanger, and the bottom surface also needs fine finishing to form, and when guaranteeing to install hanger perpendicular to the body end face.
The thickness that bolt is installed shoulder wants to guarantee the bolt pressure that will bear, different according to the diameter of bolt and land widths, the thickness of shoulder is corresponding change also, usually require shoulder wing thickness more than 15mm, shoulder links to each other the position with the arc transition more than the R5 with the hanger body, and is concentrated to eliminate stress.
Press hanger with have gentle hands during installation, contact with cylinder head to guarantee hanger, last passing with two bolts is tightened on the mounting hole on the cylinder block then, goes up enough moment on request.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
Claims (3)
1. the hanger installed of a motor narrow space, it is characterized in that, hanger (1) is contained in the crack between cylinder head (2) and the water pump backing plate (3), hanger (1) the both sides mounting hole that respectively distributes, hanger (1) is by being fixed by bolts on the engine body, a surface of contact (4) of hanger (1) contacts with cylinder cap (2), does not contact with water pump backing plate (3).
