Description
Technical field
The utility model belongs to automobile technical field, is specifically related to a kind of valve mechanism cover sealing configuration.
Background technique
When the engine operates, be filled with the machine oil be atomized in a large number in the space of valve mechanism cover and cylinder head, if poor sealing between valve mechanism cover and cylinder head, often cause the generation of the faults such as leakage of oil oil impregnate, have a strong impact on the durability of cylinder head.Existing valve mechanism cover sealing configuration as shown in Figure 1, locating slot 4 in valve mechanism cover 1 and the distance between its bolt hole 5 distant, when bolt tightening, bolt active force and the Stamping Steel Ribbon be arranged in locating slot 4 be not at same vertical plane, i.e. Stamping Steel Ribbon discontinuity, Stamping Steel Ribbon torsional deformation can be caused, affect the sealing effect between cylinder head cover and cylinder head.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed to solve above-mentioned background technology, provides the valve mechanism cover sealing configuration that a kind of sealing is stronger.
The technical solution adopted in the utility model is: a kind of valve mechanism cover sealing configuration, comprise valve mechanism cover, Stamping Steel Ribbon for sealing cylinder housing and cylinder head, described valve mechanism cover bottom margin is provided with locating slot, described Stamping Steel Ribbon and locating slot match, described valve mechanism cover edge is provided with multiple bolt hole, described valve mechanism cover bottom margin comprises curved section and straightway two-part, the locating slot on described curved section avoid the position of bolt hole along curved section outline, be positioned at the position indent camber section of bolt hole; The center line at position that bolt hole avoided by locating slot on described straightway overlaps with the center line of straightway, be positioned at the position of bolt hole along bolt hole edge indent camber section.
Further, the two ends that described valve mechanism cover bottom margin is relative are respectively first paragraph and the 6th section, and the both sides crossing with first paragraph are respectively second segment and the 3rd section, and the 6th section of two ends are respectively the 4th section and the 5th section with second segment and the 3rd section of crossing position; Described first paragraph, the 4th section and the 5th section be described curved section, described second segment, the 3rd section and the 6th section be described straightway.
Further, the center of described arcuate segment place circle overlaps with bolt hole center, and the distance between described arcuate segment and bolt hole edge is 0.2-0.5mm.
Locating slot center line on the utility model valve mechanism cover straightway overlaps with the center line of straightway, locating slot on straightway and curved section contour convergence, when bolt tightening, the active force of bolt can directly act on Stamping Steel Ribbon, Stamping Steel Ribbon uniform force, enhance sealing effect, structure is simple, reasonable in design, ensure that the sealing of valve mechanism cover and cylinder head, reduces the risk of lubricating oil leakage seepage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As in Figure 2-4, the utility model comprises valve mechanism cover 1, Stamping Steel Ribbon 3 for sealing cylinder housing 1 and cylinder head 2, described valve mechanism cover 1 bottom margin is provided with locating slot 4, and described Stamping Steel Ribbon 3 matches with locating slot 4, and described valve mechanism cover 1 edge is provided with multiple bolt hole 5.
Valve mechanism cover 1 bottom margin comprises curved section and straightway two-part, wherein, the two ends that valve mechanism cover bottom margin is relative are respectively first paragraph 11 and the 6th section 16, the both sides crossing with first paragraph 11 are respectively second segment 12 and the 3rd section of the 13, six section of 16 two ends position crossing with second segment 12 and the 3rd section 13 and are respectively the 4th section 14 and the 5th section 15; Described first paragraph 11, the 4th section 14 and the 5th section 15 be described curved section, described second segment 12, the 3rd section 13 and the 6th section 16 be described straightway.
Its distribution situation of difference that locating slot 4 distributes according to valve mechanism cover 1 bottom margin is also different, is specially: the locating slot on curved section (first paragraph 11, the 4th section 14 and the 5th section 15) avoid the position 41 of bolt hole along curved section outline, be positioned at the position 42 indent camber section of bolt hole; The center line at position 43 that bolt hole 5 avoided by locating slot on straightway (second segment 12, the 3rd section 13 and the 6th section 16) overlaps with the center line of straightway, is being positioned at the position 44 of bolt hole along bolt hole edge indent camber section.
In such scheme, the bolt hole center that on straightway and curved section, the center of all arcuate segment places circle of locating slot is corresponding with it respectively overlaps, distance between arcuate segment and bolt hole edge is 0.2-0.5mm, Stamping Steel Ribbon when suitable spacing ensures that bolt 6 is tightened in it stressed evenly.
The center line of the most of locating slot in the utility model valve mechanism cover and the line coincident at adjacent bolt hole center, Stamping Steel Ribbon 3 and locating slot 4 match, when bolt 6 is tightened, the active force of bolt 6 and Stamping Steel Ribbon 3 are on same vertical plane, on Stamping Steel Ribbon 3, each several part uniform force, enhances sealing effect, and structure is simple, reasonable in design, ensure that the sealing between valve mechanism cover 1 and cylinder head 2, reduce the risk of lubricating oil leakage seepage.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
