Description
Technical field
The present invention relates to a kind of air distributing mechanism of engine for motorcycle.
Background technique
In existing motor engine gas distribution system, camshaft is provided with a cam, an air inlet lower shake-changing arm promoted by cam and exhaust lower shake-changing arm are set respectively in these cam both sides, air inlet push rod and exhaust jacking rod is promoted respectively again by air inlet lower shake-changing arm and exhaust lower shake-changing arm, and then promote air inlet upper rocker arm and exhaust upper rocker arm by air inlet push rod and exhaust jacking rod again, finally drive intake valve and exhauxt valve opens by air inlet upper rocker arm and exhaust upper rocker arm.The air distribution structure of this structural type is complicated, less stable.
Summary of the invention
The object of the present invention is to provide a kind of structure simple and the good air distributing mechanism of engine for motorcycle of stability.
The object of the present invention is achieved like this, a kind of air distributing mechanism of engine for motorcycle, comprise camshaft, camshaft is provided with cam, and the both sides of camshaft are respectively equipped with a push rod, the upper end of push rod is connected with valve by rocking arm, lower end contacts with cam place and connects, and push rod is arc and rotates to be arranged on coupling shaft, and coupling shaft is fixedly installed on casing.Cam axle, cam promotes push rod, and push rod take coupling shaft as fulcrum, and then drives valve rocker to be subjected to displacement, thus drives valve-closing or open.
Push rod comprises inlet push rod and exhaust push rod; rocking arm comprises inlet valve rocker and exhaust valve rocker arm; valve comprises intake valve and exhaust valve; the push rod of cam side is inlet push rod; its upper end is connected with intake valve by inlet valve rocker; the push rod of cam opposite side is exhaust push rod, and its upper end is connected with exhaust valve by exhaust valve rocker arm.Cam axle, cam promotes inlet push rod and is subjected to displacement, and inlet push rod take coupling shaft as fulcrum, and inlet push rod upper end promotes inlet valve rocker and is subjected to displacement, and drives intake valve to open; Camshaft is rotated further, and cam turns over inlet push rod, and inlet push rod is that fulcrum turns round with coupling shaft, and inlet push rod upper end drives inlet valve rocker travelling backwards, IC Intake Valve Closes; Meanwhile, cam promotes exhaust push rod and is subjected to displacement, exhaust push rod upper end promotes exhaust valve rocker arm and is subjected to displacement, exhaust valve is opened, and camshaft is rotated further, and cam turns over exhaust push rod, exhaust push rod is that fulcrum turns round with coupling shaft, exhaust push rod upper end drives exhaust valve rocker arm travelling backwards, and exhaust valve closing, so circulates.
Push rod is provided with attachment hole, and push rod is located on coupling shaft by attachment hole.
In order to reduce component wear, between attachment hole and coupling shaft, be provided with packing ring.
In order to improve the stability of structure further, inlet valve rocker and exhaust valve rocker arm are arranged on pitman arm shaft, and pitman arm shaft is fixedly installed on casing.
Inlet valve rocker and exhaust valve rocker arm rotate and are arranged on pitman arm shaft.
Inlet valve rocker and exhaust valve rocker arm are equipped with rocking arm hole, and inlet valve rocker and exhaust valve rocker arm are located on pitman arm shaft respectively by rocking arm hole.
In order to reduce wear, between rocking arm hole and pitman arm shaft, be provided with packing ring.
The present invention has following beneficial effect:
1, inlet push rod of the present invention and exhaust push rod are designed to arc and rotate be arranged on coupling shaft, be fulcrum with coupling shaft when being subject to that cam promotes, thus valve rocker can be driven to be subjected to displacement, and then open or close intake valve and exhaust valve, structure is simple, good stability.
2, the present invention is easy to processing, and cost is low.
Accompanying drawing explanation
