Abstract
Provided is a chain wheel chamber cover of a diesel engine. The chain wheel chamber cover comprises a body and a bolt hole formed in the chain wheel chamber cover body, wherein the chain wheel chamber cover body is fixed to a diesel engine body through a screw so that a timing chain system in the diesel engine body can be isolated from the external environment, a pin sleeve is arranged in the bolt hole of the chain wheel chamber cover, and the pin sleeve makes contact with the screw and bears screwing force of the screw. The chain wheel chamber cover has the advantages of having a reliable installation structure and being capable of preventing a loosening phenomenon in a later period.
Description
Technical field
The utility model is about a kind of automobile component, particularly the cap structure of diesel engine sprocket wheel chamber.
Background technique
Motor is the parts that automobile is important and accurate, and it comprises many parts that cooperatively interact, and to complete the normal of motor overall operation, and provides the protection of each side for motor.
A kind of at motor wherein, diesel engine sprocket wheel chamber is also one of vitals in engine components.As a kind of supplementary equipment, be generally sprocket wheel chamber lid is provided, dailyly to provide protection to it, and provide convenience for maintenance and operation in the future.
Chain gear chamber cover is a kind of sealing part, and its function is that timing chain system and the external world are effectively isolated, and avoids in-engine oil leak to external environment.Can play the effect of sound insulation and noise reduction simultaneously.
What at present conventional traditional chain gear chamber cover adopted is metallic material manufacture, casting aluminium material for example, and it has advantages of that structural strength is higher, but its cost is relatively high, in using process, weight is relatively high, is unfavorable for operation and maintain and replace in the future.
For this reason, need to develop a new chain gear chamber cover, to meet, reduce production costs, safe and reliable, and reach more light-weighted designing requirement.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of diesel engine sprocket chamber cover, described chain gear chamber cover has body, with the bolt hole being arranged on described body, described body is also fixed on vehicle body through screw, so that the timing chain system in described vehicle body and external environment are isolated, wherein: be provided with guide in the bolt hole of described chain gear chamber cover, the power that screws that described guide contacted and carried described screw with described screw.
Alternatively, described guide runs through the body of whole described chain gear chamber cover in the longitudinal direction, with the installation to described screw, provides positioning and guiding.
Alternatively, the body of described chain gear chamber cover is through injection moulding integrated molding.
Alternatively, described guide is one-body molded by Steel material.
Alternatively, the outside of described body is the arc of protrusion.
Alternatively, the inner side of the described body clathrate that alternate in length and breadth stiffening rib forms of serving as reasons.
Alternatively, the attachment face of described chain gear chamber cover has boss structure, to prevent that existing of two component height difference from causing chain gear chamber cover distortion.
Alternatively, on described body, there is material reducing hole, improve Shooting Technique.
Alternatively, described material reducing pore size distribution is on the outward edge of described body inner side.
Chain gear chamber cover in the utility model has reliable mounting structure, can fully install and isolate to external world, also can prevent the loosening phenomenon in the time in later stage simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model general assembly schematic diagram;
Fig. 2 is the boss partial schematic diagram at A place in Fig. 1;
Fig. 3 is chain gear chamber cover schematic diagram;
Fig. 4 is the partial schematic diagram of B place guide in Fig. 3; With
Fig. 5 is schematic diagram inside the utility model body.
Reference character: 1 body, 2 guidees, 3 stiffening ribs, 4 boss structures, 5 material reducing holes.
Embodiment
As shown in Figures 1 to 4, the utility model provides a kind of diesel engine sprocket chamber cover, described chain gear chamber cover has body 1, with the bolt hole being arranged on described body 1, described body is also fixed on vehicle body through screw, so that the timing chain system in described vehicle body and external environment are isolated, wherein: be provided with guide 2 in the bolt hole of described chain gear chamber cover, the power that screws that described guide contacted and carried described screw with described screw.
As improvement of the present utility model, described guide 2 runs through the body 1 of whole described chain gear chamber cover in the longitudinal direction, with the installation to described screw, provides positioning and guiding.
Preferably, the body 1 of described chain gear chamber cover is through injection moulding integrated molding.Owing to adopting the comparatively plastic material of lightweight to carry out injection moulding, so this body weight is little, and cost is low.
In preferred embodiment, described guide 2 is one-body molded by Steel material.It can bear and screw more greatly power, and during with 1 work of described injection moulding body, also will provide protection to body 1.
As preferred embodiment of the present utility model, the outside of described body 1 is the arc of protrusion.The protection in outside is provided.And as further improving, the inner side of described body 1 clathrate that alternate in length and breadth stiffening rib 3 forms of serving as reasons.From inside, provide support, after being subject to outside impact, still can play the effect of protection and resistance to deformation.
As a preferred embodiment of the present utility model, the attachment face of described chain gear chamber cover has boss structure, to prevent that existing of two component height difference from causing chain gear chamber cover distortion.More reliable in its using process, durable.
As another preferred embodiment of the present utility model, on described body, there is material reducing hole 5, improve Shooting Technique.Preferably, described material reducing hole 5 is distributed on the outward edge of described body 1 inner side.
It will be appreciated by persons skilled in the art that this chain gear chamber cover can be extended to the lid plate accessory that other all kinds on motor have identical function.
The utility model can be at chain gear chamber cover bolt hole Position Design steel drive pin cover, in order to location and pressure-bearing bolt force.Reduce production costs simultaneously, reach more light-weighted designing requirement, meanwhile, solved the defect of strength deficiency, at chain gear chamber cover inner side design stiffening rib, increase its structural strength; In addition, designed chain gear chamber cover sealing surface is across two component, at chain gear chamber cover attachment face design boss structure, to prevent that existing of two component height difference from causing chain gear chamber cover distortion.
Should be appreciated that the claimed scope of the utility model is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claims provide, with and dependent claims.
