Also include buffer stopper, be arranged on the support on subframe, and in described bending section helical spring.
The invention has the beneficial effects as follows:
Helical spring centrage one end is changed to circle arc curve, make the tangent line of circle arc curve and installed surface contact point with
The normal parallel of installed surface, so eliminates the angle of the centrage of helical spring and the normal of installed surface.
Meanwhile, the radius r making circle arc curve is equal to helical spring centrage with the intersection point of swing arm installed surface to swing arm rotation
Turn the distance at center, center of arc on bottom arm bush 2 centrage, so, circle arc curve point of intersection tangent line all the time
The helical spring installed surface of vertical lower swing arm, circle arc curve and spiral shell when when swing arm moves up and down, helical spring stretches or compresses
The angle that the tangent line of rotation spring installed surface contact point is not produced all the time with the normal of installed surface, eliminates the mill in motor process
The problems such as damage, abnormal sound.
