In view of the problems that the existing single-arm shock absorber in the prior art is poor in shock absorption effect, high in requirement on a connection point structure and unsafe, the electric friction multi-connecting-rod shock absorption system for solving the problems is provided.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
an electric motorcycle multi-connecting-rod damping system comprises a damping rod, a frame and a rear bottom fork, wherein the upper part of the damping rod is rotatably connected with the upper part of the frame, the electric motorcycle multi-connecting-rod damping system also comprises a suspension pull rod and a suspension rocker arm, the suspension rocker arm is triangular, three corners of the suspension rocker arm are respectively provided with a damping mounting lug, a bottom fork mounting lug and a pull rod mounting lug, the lower part of the damping rod is rotatably connected with the damping mounting lug, the bottom fork mounting lug is rotatably connected with the rear bottom fork through a bottom fork mounting frame, the pull rod mounting lug is rotatably connected with the upper part of the suspension pull rod, the suspension pull rod is rotatably connected with the lower part of the frame through a mounting bracket, and the height of the damping mounting lug is lower than that of the bottom fork mounting lug in a connection state; set up like this and hang the rocking arm and make the hookup location of the lower part of shock attenuation pole be less than the hookup location who hangs rocking arm and back chain stay, it can make the focus step-down of shock attenuation pole to set up like this, the rear wheel is when upwards moving owing to rugged road surface, can drive back chain stay rebound, back chain stay rebound drives chain stay installation journal stirrup rebound, thereby make and hang rocking arm anticlockwise rotation, then give a power of pulling down of shock attenuation pole, can make unnecessary frequent the compressing of shock attenuation pole like this, the life of extension shock attenuation pole, and each tie point atress is even, the structural rigidity requirement to single tie point has been reduced, and safety is higher.
Further limiting, the bottom fork mounting rack and the rear bottom fork are fixedly connected to connect the rear bottom forks at the left end and the right end into a whole; the rear bottom fork at the left end and the right end is connected into a whole through the bottom fork mounting frame, so that the left end and the right end of the rear wheel are higher in synchronism, and the bottom fork structure is more stable.
Further, the mounting bracket is fixedly connected with the lower part of the frame.
The utility model discloses compare in prior art's beneficial effect for the lower part tie point of shock attenuation pole is lower make the focus of shock attenuation pole lower, through hanging rocking arm with shock attenuation pole, chain stay mounting bracket and installing support rotatable coupling, can be so that the atress is more even, the life of shock attenuation pole is longer, more safety.
