Abstract
The invention relates to a timing cover, which integrates a water pump and a crankshaft front oil seal and is applied to an engine. The cover at a front end is made into a whole; in order to save engine spacial collocation, the water pump and the crankshaft front oil seal are integrated on the timing cover. Moreover, a water chamber part formed by a water pump shell body and a cylinder body part is directly machined on the cover. The timing cover is of an integrated structure, and the cover body is formed through direct cast molding; and the timing cover has simple process and high production efficiency.
Description
Technical field
The present invention relates to a kind of cover cap, be specifically related to a kind of timing cover.
Background technique
At present cover cap all is to be made by steel plate or plastics, forms airtight space with the front-end face of cylinder body, and Timing Belt, belt pulley, tension device etc. in the engine-driven gearing are wherein airtight.Because annex on every side is a lot, the size of timing cover is very big.
In order to guarantee assembling, timing cover to be made two-part usually.
The timing cover significant feature is performances such as sealing, noise reduction.Engine timing belt wheel, stretcher, driving gear, belt etc. are closed, the purpose that other part and timing system is isolated is exactly, prevent that timing mechanism is subjected to the pollution of foreign material such as oil, water, mud, also prevented the bump of other foreign matter in addition, engine timing system and cylinder body front end is airtight, also play a positive role for the noise that reduces motor, therefore, timing cover has obtained extensive use on motor.
The effect of water pump be make cooling water in motor with certain flow and pressure to circulate, to guarantee piston, cylinder cap, high temperature parts such as cylinder body can access cooling timely, make the front end of motor to guarantee to start the function proper functioning like this.Water pump shell and water pump vane be cylinder iron casting generally, some pump case aluminium alloy casting, and impeller can be suppressed or the steel plate punching press with engineering plastics, because the housing of water pump takies certain volume, timing cover is in order to be closed water pump, usually need do cover cap very greatly, make that the layout of motor is very big.
In order to guarantee assembling, timing cover need be made two-part usually, in addition in order to dodge bent axle, all need out a hole on the cover cap, because certain slit is arranged, the noise reduction for train has certain influence like this.
In sum, have following technical problem in the prior art: two-part form of (1) cover cap causes noise reduction bad; (2) processing difficulties, the cost height; (3) the engine arrangement space is narrow.
Summary of the invention
The object of the present invention is to provide a kind of one-body moldedly and be integrated with the timing cover of part, whole cover cap is optimized, and makes full use of the space, reduce the size of cover cap as far as possible, reduce the overall space of motor.Another object of the present invention is to provide a kind of hydroecium part the direct timing cover of on cover cap, processing, simplify course of working, cut down finished cost.
The invention discloses a kind of integrated water pump on the motor and timing cover of bent axle Front oil seal of being applied in, the cover cap of front end is made an integral body, and, water pump, bent axle Front oil seal are integrated on the timing cover in order to save the layout between engine air.And, directly on cover cap, process the hydroecium part that forms with cylinder part on the water pump cover.Timing cover is structure as a whole, and the cover cap body is cast molding directly, and technology is simple, the manufacturing efficiency height.
Concrete technological scheme is as follows:
A kind of timing cover, the part of engine cylinder-body front end are integrated on the described timing cover, and described timing cover is structure as a whole.
The part of described engine cylinder-body front end comprises water pump and/or crank shaft oil seal.
Described timing cover comprises a cover cap body.
Form a hydroecium with the engine cylinder body portion on the water pump cover of water pump.
A hydroecium part is integrated on the cover cap body.
The material selection plastics of timing cover.
The cover cap body is direct cast molding.
This part of hydroecium directly processes on cover cap.
Integrated water pump and bent axle Front oil seal on the described timing cover.
Compare with present prior art, the present invention is under the prerequisite that satisfies the cover cap function, on the basis of the layout that has taken into full account motor, water pump, crank shaft oil seal are integrated on the timing cover, have reduced the car load arrangement space like this, make motor compact more, because the hydroecium that will on water pump cover, form with cylinder part, directly process on cover cap, make easy processing, cost also reduces in a large number.
Description of drawings
Fig. 1 is a timing cover member schematic representation of the present invention
Among the figure:
1-cover cap body, 2-crank shaft oil seal, 3-hydroecium, 4-water pump
Embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
With reference to Fig. 1, timing cover of the present invention, it comprises pad cover cap body (1), crank shaft oil seal (2), water pump (4) composition.Because integrated to crank shaft oil seal (2) and water pump (4) strengthened the sealability to motor head, simultaneously, saved the arrangement space of motor, in addition on the one hand, also make motor integral body compactness more.It adopts plastic materials, like this can cover cap body (1) direct cast molding, technology is simple, be fit to produce in enormous quantities, the manufacturing efficiency height, another side can be recycling for waste and old material, helps environmental protection.Hydroecium (a 3) part is integrated on the cover cap body (1), because the pump case easy processing is compared in the processing of cover cap, can save cost like this.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
