Description
Technical field
The present invention relates to the design and optimization of motorcycle part, is the improvement to the driving engine suspension assembly of pedal motorcycle specifically.
Background technology
For pedal motorcycle, a force of inertia of the driving engine that those skilled in the art are known is with same direction move back and forth (100% crankshaft counterbalance), by with engine suspension on reel cage, its angle of suitable configuration and the vibration of the driving engine swing energy as reel cage is absorbed suppresses the purpose that vibration is communicated to car body thereby reach.
But, actual combination reel cage driving engine, the unequal reason of crankshaft counterbalance during owing to volume production also exists and a different vibration of force of inertia direction that designs, particularly also there is the higher secondary inertia force vibration of cycle in the vibration-direction at piston, can not ignore the impact of these vibration on vehicle integral body for the locomotive design person.
Reel cage in the conventional art is generally single reel cage design, in order to absorb the vibration component with an above-mentioned force of inertia different directions (mainly being secondary inertia force), need to as frame sides, start the bearing portions configuration vibrationproof rubber bush of pusher side center of gyration, absorb vibration with an above-mentioned force of inertia main component different directions with this, and consider that this rubber bush need adopt the more soft lining of rubber capacity in order fully to absorb vibration.
But, soft rubber bush can make horizontal (overall width direction) rigidity of vehicle integral body, torsional rigid descend, road-holding property when running at high speed is worsened, because the engine drive moment of torsion during vehicle start becomes the power that makes the change of driving engine posture, also exist the propulsive effort when making some startings to produce the shortcoming of loss.In addition, when carrying one people and carrying two people, driving engine changes greatly with the relative angle of reel cage, and this riding stability on locomotive has certain impact.
Summary of the invention
