[0015] Secondly, "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or selected from other embodiments. Embodiment one
[0016] Please refer to Figs. 1-3 The utility model provides a novel swing arm suspension, including front wave tank 1, upper swing arm 2, half tooth screw 3, lower swing arm 4, C seat connecting piece 5 and torsion spring 6, and front wave tank 1 is connected with lower swing arm 4 and upper swing arm 2 through the half tooth screw 3 of custom, and upper swing arm 2 and lower swing arm 4 are connected with C seat connecting piece 5 through half tooth screw 3, and torsion spring 6 is assembled on front wave tank 1 and upper swing arm 2, and through the torsion of it, lower swing arm 4 is pressed down, and the chassis is supported to rise.
[0017] The technical scheme solves the problems that the existing double fork arm suspension structure has obvious defects, the internal structure layout is very crowded in the vehicle chassis with a small ratio such as 1:43, the traditional upper and lower swing arms and shock spring are centrally installed at the steering structure, leading to difficult space utilization, especially the processing of spring shock is extremely tricky, and it is difficult to realize reasonable layout and effective shock function in limited space. Embodiment two
[0018] Please refer to Figs. 1-3As shown, the C-shaped connector 5 can form an upward and downward arc displacement with the upward swing of the swing arm, the front gearbox serves as the pivot point of the upper swing arm 2 and the lower swing arm 4, and the upper swing arm 2 and the lower swing arm 4 are assembled with the torsional spring 6 through the half tooth screw 3, the upper swing arm 2 is assembled on the front gearbox 1 and the C-shaped connector 5 through the half tooth screw 3, and serves as one of the pivot points of the torsional spring 6
[0019] The working principle of the utility model is: first, the front gearbox 1 serves as the pivot point of the upper swing arm 2 and the lower swing arm 4, and is connected with the upper swing arm 2 and the lower swing arm 4 through the half tooth screw 3, when the vehicle is running, the upper swing arm 2 and the lower swing arm 4 move around it as the center, the upper swing arm 2 and the lower swing arm 4 are also fixed with the C-shaped connector 5 through the half tooth screw 3, the C-shaped connector 5 is connected with the steering cup and the hub tire, when the vehicle runs on the normal road surface, the force of the torsional spring 6 makes the swing arm press downward, and then supports the whole chassis, when the tire meets irregular terrain, such as protrusion or depression, the tire will jump upward, driving the upper swing arm 2 and the lower swing arm 4 to move upward, at this time, the torsional spring 6 will be stretched or extruded, and deformation is generated, according to the elastic property of the torsional spring 6, it will exert a downward torsion force opposite to the movement direction of the upper swing arm 2 and the lower swing arm 4, the torsion force makes the upper swing arm 2 and the lower swing arm 4 return to normal, driving the tire to return to the normal position, so as to buffer the impact force generated by the change of terrain, and the shock-absorbing effect is realized.
