Description
Technical field
This utility model relates to technical field of automobile, more particularly, it relates to a kind of air valve tappet of engine.
Background technology
Valve tappet is a critical piece in valve train group, and tappet is the driven member of cam, and its effect is will to pass to push rod or valve from the motion of cam and active force, and the side force that simultaneously applied also subject to cam is also passed along body or cylinder head.Operationally, its bottom surface and cam contact, owing to contact area is little, contact pressure is big, therefore weares and teares relatively serious, of long duration stuck phenomenon of rupture then can occur, thus have impact on engine work for tappet.And owing to the weight of valve tappet is relatively big, cause work heat production serious, cause the too much consumption of fuel source.
Accordingly, because prior art exists above-mentioned technological deficiency, it is those skilled in that art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of air valve tappet of engine, it is intended to solves cam present in prior art and contacts with tappet bottom surface and easily block, and causes the problem that fuel source wastes.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of air valve tappet of engine, including barrel-type casing, inner chamber, drive boss, tappet base, chute and strip lightening hole, described barrel-type casing top is tappet base, described tappet base is welded to connect with described barrel-type casing, described barrel-type casing one end is closed by described tappet base, it is inner chamber in described barrel-type casing, described tappet chassis outer side is provided with chute, described chute matches with cam, it is provided with driving boss inside described tappet base, described driving boss contacts with valve afterbody, told barrel-type casing sidewall is provided with multiple strip lightening hole, described strip lightening hole is uniformly arranged.
Preferably, also include that drainage screen, described drainage screen are located on described strip lightening hole.
Of the present utility model having the beneficial effect that by arranging chute on tappet chassis outer side face, making chute cooperate with cam, when cam rotation, it can slide in chute, is pressed downwards by valve tappet；Not only make cam engagement tight, and reduce the risk blocked；And strip lightening hole is set on barrel-type casing, thus reduce valve tappet overall weight, reduce Fuel Dosage, and drainage screen is set on strip lightening hole such that it is able to oil is filtered.This utility model simple in construction, easy to use, tappet base is tightly combined with cam, and fuel oil expends few.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of tappet base in this utility model.
In figure: 1 barrel-type casing；2 inner chambers；3 drive boss；4 tappet bases；5 chutes；6 strip lightening holes；7 drainage screens.
Detailed description of the invention
This utility model provides a kind of air valve tappet of engine, this utility model simple in construction, and easy to use, tappet base is tightly combined with cam, and fuel oil expends few.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear and detailed description, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiment.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of air valve tappet of engine as illustrated in fig. 1 and 2, including barrel-type casing 1, inner chamber 2, drive boss 3, tappet base 4, chute 5 and strip lightening hole 6, described barrel-type casing 1 top is tappet base 4, described tappet base 4 is welded to connect with described barrel-type casing 1, described barrel-type casing 1 one end is closed by described tappet base 4, it is inner chamber 2 in described barrel-type casing 1, it is provided with chute 5 outside described tappet base 4, described chute 5 matches with cam, driving boss 3 it is provided with inside described tappet base 4, described driving boss 3 contacts with valve afterbody, told barrel-type casing 1 sidewall is provided with multiple strip lightening hole 6, described strip lightening hole 6 is uniformly arranged.
Further, also include that drainage screen 7, described drainage screen 7 are located on described strip lightening hole 6.The setting of drainage screen 7, it is possible to oil return is filtered, and make oil return oil return from strip lightening hole 6, thus reduce oil return resistance.
This utility model in use, by arranging chute 5 on tappet base 4 lateral surface, makes chute 5 cooperate with cam, and when cam rotation, it can slide in chute 5, is pressed downwards by valve tappet；Not only make cam engagement tight, and reduce the risk blocked；And strip lightening hole 6 is set on barrel-type casing 1, thus reduce valve tappet overall weight, reduce Fuel Dosage, and drainage screen 7 is set on strip lightening hole 6 such that it is able to oil is filtered.This utility model simple in construction, easy to use, tappet base is tightly combined with cam, and fuel oil expends few.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, and between each embodiment, identical similar portion sees mutually.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.Multiple amendment to these embodiments is apparent from for those skilled in the art, and generic principles defined herein can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
