Detailed description of the invention
The mentality of designing of this suspension is, the restrained ACTUATOR of wheel and motion thereof constrain in the direction being perpendicular to vehicle body, by the moment of flexure to constrained action cylinder that reasonable tilting helical spring balance car heavy sensation of the body amount produces, reduce constrained action cylinder opplied moment thus reducing abrasion to its generation, surface resistance that running resistance when being travelled by double; two ACTUATOR balancing vehicles, Uneven road and hindering is produced, the brake force of brake generation. It is structurally characterized in that wheel to be limited in a vertical direction by suspension and move.
Defer to technique scheme, as it is shown in figure 1, a kind of unidirectional restricted type automotive suspension, including the constrained action cylinder 1 being vertically mounted on axletree 7, constrained action cylinder 1 includes constraint cylinder 101 and is assemblied in the piston rod 102 in constraint cylinder 101, and piston rod 102 can slide in constraint cylinder 101; Described constraint cylinder 101 is arranged on vehicle frame, and piston rod 102 is supported on axletree 7. As it is shown on figure 3, be the structural representation of constrained action cylinder 1. Piston rod 102 can constraint cylinder 101 in slide, but not with constraint cylinder 101 top contact; Closely cooperating between piston rod 102 and constraint cylinder 101, and use grease lubrication and sealing, the effect of piston rod 102 and constraint cylinder 101 is the balance of the direction of motion of constraint mechanism and moment. Top in constraint cylinder 101 is provided with limiting card 103, for limiting the position of piston rod 102 motion.
Constrained action cylinder 1 is arranged a pair, is connected by transverse arm 5 between the piston rod 102 of two constrained action cylinders 1, and transverse arm 5 is arranged on axletree 7.
Piston rod 102 and the transverse arm 5 of two constrained action cylinders 1 connect into an entirety, simultaneously one end connecting cross arm 5 of axletree 7, and the other end connects wheel 4. Being provided with the first spring tray 6 on axletree 7, one end of the first spring tray 6 is connected on piston rod 102, and the other end is connected on axletree 7; Angle between first spring tray 6 and axletree 7 is acute angle. Vehicle frame is provided with the second spring tray, between the first spring tray 6 and the second spring tray, is provided with double-acting shock absorber 3; Namely double-acting shock absorber 3 favours axletree 7 setting. Double-acting shock absorber 3 outer cover is equipped with helical spring 2, and the two ends of helical spring 2 are connected on the first spring tray 6 and the second spring tray.
During running car, tire is subject to ground reaction force and is delivered to constrained action cylinder 1 by axletree 7 and transverse arm 5, forms the clockwise moment of flexure to constrained action cylinder 1 compression helical spring 2; Helical spring 2 after compression produces the anticlockwise moment of flexure of constrained action cylinder 1. The angle properly arranging helical spring 2 makes moment of flexure balance, and reduces the internal stress of ACTUATOR thus reducing its abrasion and fatigue damage. The design of double; two constrained action cylinders 1, when balancing vehicle travels, road surface acts on the moment of flexure that the running resistance of wheel 4 produces, it is ensured that the stability of suspension frame structure. Moved (as shown in Figure 5) along the direction of vertical vehicle body when beating by embodiment of above wheel 4, it is achieved wheelspan and the constant purpose of wheelbase.
