Problems solved by technology

In the case of sharing one cam, either the cam profiles of the two cannot meet the design requirements, or one of the cam profiles is sacrificed, which eventually leads to the inability to control the intake and exhaust valves according to the regular movement during the intake and exhaust processes. The opening and closing of the engine cannot achieve the expected timing of gas distribution, which eventually leads to low engine power and torque and poor performance

Embodiment Construction

[0018] figure 1 It is a structural schematic diagram of the present invention, as shown in the figure, the motorcycle engine gas distribution mechanism of the present embodiment includes an intake valve 4, an exhaust valve 5 and a camshaft for driving the intake valve 4 and the exhaust valve 5 to open 14. The intake valve 4 and the exhaust valve 5 are driven by different cams. In the existing motorcycle engine, the intake and exhaust cams 13 share the same cam drive. In this case, due to the profile of the intake and exhaust cams 13 The lines should be different, so the 13-type lines of the intake and exhaust cams either cannot meet the design requirements, or one of the cam lines is sacrificed, causing the engine to fail to achieve the expected timing gas distribution, while the motorcycle engine gas distribution system of the present invention mechanism, the intake valve 4 and the exhaust valve 5 are driven by different cams, so that designers can design the corresponding ca...

Abstract

The invention discloses a valve mechanism of a motorcycle engine. The valve mechanism of the motorcycle engine comprises an intake valve, an exhaust valve and a camshaft used for driving the intake valve and the exhaust valve to be opened. The intake valve and the exhaust valve are driven by different cams, so designers can design corresponding cams on the camshaft according to laws of motion in the intake and exhaust process of the motorcycle engine, requirements of timing for intake and exhaust of the motorcycle engine can be guaranteed, expected timing valve can be achieved, finally, power and torque of the motorcycle engine are greatly improved, and the performance of the motorcycle engine is improved.

Description

technical field [0001] The invention relates to the field of motorcycle parts, in particular to a motorcycle engine gas distribution mechanism and the motorcycle engine. Background technique [0002] In the existing motorcycle engine gas distribution system, only one cam is arranged on the camshaft, and an intake lower rocker arm and an exhaust lower rocker arm driven by the cam are respectively arranged on both sides of the cam, The rocker arm and the exhaust lower rocker arm push the intake ram and the exhaust ram, and then the intake ram and the exhaust ram push the intake upper rocker and the exhaust upper rocker, and finally the intake upper rocker Arm and exhaust upper rocker arm actuates the intake and exhaust valves to open. In the gas distribution system of this structure, only one cam is arranged on the camshaft, and the same cam drives two sets of transmission mechanisms at the same time to realize the opening of the intake valve and the exhaust valve. From the ...
