Abstract
The invention discloses a kind of I. C engine distribution mechanisms, including hydraulic tappet, rocking arm, valve and camshaft, the both ends setting of the camshaft and valve difference respective rocker arm, camshaft and valve are respectively positioned on the lower section of rocking arm, and the hydraulic tappet is located at the top of rocking arm.It is compact-sized, it occupies little space, the height of cylinder cap can be reduced, to effectively reduce the weight of cylinder cap, increase cylinder cover structure intensity, be more favorable to the maintainability of valve actuating mechanism.
Description
Technical field
The present invention relates to technical field of internal combustion engines, more particularly, to a kind of I. C engine distribution mechanism.
Background technology
Overhead camshaft is that camshaft is placed on cylinder cap, directly drives the parts of the valve actuating mechanisms such as rocking arm, valve,
Compared with bottom type camshaft, part that overhead camshaft participates in moving back and forth to be lacked more, therefore enormously simplifies gazogene
The structure of structure alleviates the weight of engine, is more advantageous to the rotating speed for improving engine.
The arrangement of major part overhead camshaft is convex as shown in Fig. 2, hydraulic tappet and valve are arranged in below rocking arm at present
Wheel shaft is arranged in the upper surface of rocking arm, and this arrangement makes cylinder cap height higher, to which the structure for affecting cylinder cap entirety is strong
Degree；It needs to dismount camshaft when hydraulic tappet and rocking arm are safeguarded simultaneously, is unfavorable for the maintenance of entire valve actuating mechanism.
Invention content
In view of the shortcomings of the prior art, technical problem to be solved by the invention is to provide a kind of I. C engine distribution mechanism, with
Reach compact-sized, the purpose to occupy little space.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
The I. C engine distribution mechanism, including hydraulic tappet, rocking arm, valve and camshaft, the camshaft and valve point
The both ends of other respective rocker arm are arranged, and camshaft and valve is respectively positioned on the lower section of rocking arm, and the hydraulic tappet is located at the top of rocking arm.
The rocking arm corresponds to camshaft one end and is equipped with idler wheel, and camshaft is located at the lower section of idler wheel.
The lower end of the hydraulic tappet is equipped with bulb, and bulb is located above rocking arm.
The hydraulic tappet is between camshaft and valve.
The outer rim of the idler wheel is in contact with camshaft.
The bulb is in contact with rocking arm top.
Compared with prior art, the present invention haing the following advantages：
The I. C engine distribution mechanism is reasonable in design, and in the lower section of rocking arm, hydraulic tappet is arranged in be shaken cam shaft arrangement
The top of arm, it is compact-sized, it occupies little space, the height of cylinder cap can be reduced, to effectively reduce the weight of cylinder cap, increase cylinder
Lid structural strength is more favorable to the maintainability of valve actuating mechanism.
Description of the drawings
The content expressed by each width attached drawing of this specification and the label in figure are briefly described below：
Fig. 1 is air distribution structure schematic diagram of the present invention.
Fig. 2 is existing air distribution structure schematic diagram.
In figure：
1. hydraulic tappet, 2. rocking arms, 3. valves, 4. camshafts.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
As depicted in figs. 1 and 2, the I. C engine distribution mechanism, including hydraulic tappet 1, rocking arm 2, valve 3 and camshaft 4；
Wherein, camshaft 4 and valve 3 distinguish the both ends setting of respective rocker arm 2, and camshaft and valve is respectively positioned on the lower section of rocking arm, hydraulic pressure
Tappet 1 is located at the top of rocking arm 2.
Rocking arm 2 corresponds to camshaft one end and is equipped with idler wheel, and camshaft is located at the lower section of idler wheel, outer rim and the camshaft phase of idler wheel
Contact.
Hydraulic tappet 1 is between camshaft and valve, and the lower end of hydraulic tappet is equipped with bulb, and bulb is located on rocking arm
Side, bulb are in contact with rocking arm top.
Camshaft 4 be mounted on rocking arm lower section, hydraulic tappet be mounted on rocking arm top, camshaft by drive rocking arm come
Drive valve opening and closing, hydraulic tappet to rocking arm provide support and compensate between rocking arm and valve it is that may be present between
Gap.
It is compact-sized, it occupies little space, the height of cylinder cap can be reduced, to effectively reduce the weight of cylinder cap, increase cylinder
Lid structural strength is more favorable to the maintainability of valve actuating mechanism.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as use the present invention design and technical solution carry out various unsubstantialities improvement, or it is not improved will
The design and technical solution of the present invention directly applies to other occasions, within protection scope of the present invention.
