Beneficial effect lies in: advance, the exhaust tesistance is little, can increase the fresh charge of internal -combustion engine and the compression ratio that improves the gasoline engine for the dynamic performance and the economic performance reinforcing of internal -combustion engine, inertial force, vibration and deformation are all less, have improved the high speed performance of internal -combustion engine, can obtain more application on high rotational speed, high -performance internal -combustion engine, and the valve is heat -resisting, wear -resisting and corrosion -resistant.
Description
Technical field
The utility model belongs to automobile component apparatus field, is specifically related to a kind of car combustion engine distribution mechanism.
Background technology
I. C engine distribution mechanism is the mechanism of controlling combustion engine air inlet and exhaust, oil engine is after completing a working cycle, in order to the waste gas after expansion working must be discharged cylinder by lasting work, and suck the fresh amount of filling (air or inflammable mixture) in time, the each cylinder working order of oil engine is pressed by distribution mechanism, open and close in good time into, blast gate or enter, venting port (such as two cycle internal combustion engine), to ensure abundant ventilation, distribution mechanism can be divided into side to put air gate type and overhead valve formula two class by the mode that valve is arranged on oil engine, along with the development of China's economy, vehicle has spread all over huge numbers of families, design rational I. C engine distribution mechanism and also become more and more important, but present distribution mechanism also also exists the serious problem of at high temperature service wear.
Practical novel content
The purpose of this utility model is just to provide a kind of car combustion engine distribution mechanism in order to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of car combustion engine distribution mechanism, comprising push rod, weighshaft, cotter seat and folder lock groove, cam upper end is provided with tappet, and tappet upper end is provided with push rod, promoting tappet, push rod reciprocating by the cam on camshaft; weighshaft side is provided with rocking arm, and rocking arm is waved around weighshaft, and the lower end of cotter seat is provided with valve spring; the lower end of valve guide bushing is provided with valve; the lower end of valve is provided with valve seating, valve upper end is provided with folder lock groove, and the folder lock lower end of groove is provided with valve limit.
In said structure, cam on camshaft promotes tappet, push rod reciprocating, and the top, upper top of push rod pushes away one end of rocking arm, rocking arm is waved around weighshaft, pushes away valve under rocking arm another end, valve is opened, while also compression valve spring. When valve needs to close, the rocking arm by cam drive no longer pushes down valve rod end, and valve spring is upheld and closed valve, in order to make valve can closely close at work, leaves gap between valve rod end and rocking arm end or cam.
As preferred version of the present utility model: cam is connected with tappet, tappet is connected with push rod.
As preferred version of the present utility model: weighshaft is connected with rocking arm, valve spring is fixed on cotter seat.
As preferred version of the present utility model: valve is connected with valve seating, valve guide bushing is connected with valve.
Useful effect is: inlet and outlet resistance is little, the fresh amount of filling of oil engine can be increased and improve the compression ratio of petrol motor, make the dynamic performance of oil engine and economic performance enhancement, mass force, vibration and distortion are all less, improve the high speed performance of oil engine, obtaining more application on high rotating speed, high performance oil engine, valve is heat-resisting, wear-resisting and corrosion-resistant.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of car combustion engine described in the utility model distribution mechanism;
Fig. 2 is the air valve structure figure of a kind of car combustion engine described in the utility model distribution mechanism.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 2, a kind of car combustion engine distribution mechanism, comprise push rod 3, weighshaft 4, cotter seat 6 and folder lock groove 11, cam 1 upper end is provided with tappet 2, tappet 2 upper end is provided with push rod 3, tappet 2 is promoted by the cam 1 on camshaft, push rod 3 is reciprocating, weighshaft 4 side is provided with Rocker arm 5, Rocker arm 5 is waved around weighshaft 4, cotter seat 6 times ends are provided with valve spring 7, valve guide bushing 8 times ends are provided with valve 9, valve 9 times ends are provided with valve seating 10, valve 9 upper end is provided with folder lock groove 11, folder lock groove 11 times ends are provided with valve limit 12.
In said structure, the cam 1 on camshaft promotes tappet 2, push rod 3 reciprocating, and top, the upper top of push rod 3 pushes away one end of Rocker arm 5, Rocker arm 5 is waved around weighshaft 4, pushes away valve 9 under Rocker arm 5 another end, valve 9 is opened, simultaneously also compression valve spring 7. When valve 9 needs to close, the Rocker arm 5 driven by cam 1 no longer pushes down valve 9 rod end, and valve spring 7 is upheld and closed valve, in order to make valve 9 can closely close at work, leaves gap between valve 9 rod end and Rocker arm 5 end or cam 1.
As preferred version of the present utility model: cam 1 is connected with tappet 2, tappet 2 is connected with push rod 3, and weighshaft 4 is connected with Rocker arm 5, and valve spring 7 is fixed on cotter seat 6, valve 9 is connected with valve seating 10, and valve guide bushing 8 is connected with valve 9.
More than show and describe ultimate principle of the present utility model, main feature and advantage. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model is defined by appending claims and effect thing thereof.
