Shock absorber system for invalid vehicle, comprises pair of rotary arms connected to front wheels and damping parts

摘要

A pair of left and right rotary arms (61) have a hinged end (612) and the opposite connecting end is rotatably connected to the left or right front wheel (5). Two rotary pins (611) secured to the vehicle frame (4) behind a rail (44) extending between and above the front wheels extend parallel to the front wheel rotation axes and are used to form a rotary joint between the hinged end of the arm and the vehicle frame. Two damping parts (62) connect one of the arms to the rail. When the front wheels travel over an obstacle, they are kept substantially perpendicular to the road surface.
