Abstract
The utility model relates to a follow-up steering axle of an independent air hanger bracket, comprising a left air bag assembly, a right air bag assembly, a left air bag bearing seat assembly, a right air bag bearing seat assembly, a left damper assembly, a right damper assembly and a steering system, wherein the steering system consists of a left steering knuckle arm, a right steering knuckle arm, a left steering tie rod, a right steering tie rod, a left steering damper, a right steering damper, a fan-shaped rocker arm, a left locking cylinder and a right locking cylinder. The follow-up steering axle of the independent air hanger bracket has the following advantages: an axle is controlled to do or not to do follow-up steering through the locking and unlocking of the locking cylinders, so that on the one hand, the generated abnormal abrasion of follow-up axle tires due to the discordant movement of three axles when a passenger car runs in a non-linear manner is overcome so that the service life of the tires is prolonged, on the other hand, the third axle of the passenger car is used as a follow-up axle so that the moving coordination of three shafts can be greatly strengthened in the steering process of the passenger car, and the travelling performance of the passenger car is optimized sufficiently; and simultaneously, the follow-up steering axle adopts an independent hanger bracket structure, thus improving the comfortableness of the passenger car to the maximum extent.
Description
Technical field:
The utility model relates to a kind of suspension device for vehicle, more specifically to a kind of following steering axle of independent air suspension.
Background technology:
Along with the formulation of Chinese automobile new standard, passenger vehicle length overall restriction is further relaxed, and length can reach 13.7 meters, therefore, the also corresponding increase of load, in this case, the twin shaft passenger vehicle has been difficult to meet the demands, needs to adopt three passenger vehicles.As the follow-up bridge of passenger vehicle third axle, when passenger vehicle goes as non-rectilinear, produce the follow-up bridge Abnormity abrasion about tyre owing to the motion of three bridges is inharmonious, not only greatly reduce the service life of tire, also the running car performance is produced very big influence.The follow-up bridge Abnormity abrasion about tyre from the dynamics analysis major cause is: because centnifugal force etc. when ground-surface lateral inclination, side direction wind or curve driving; Produce ground in the face of the side-force reaction of wheel center along the Y direction; When the suffered side-force reaction of tire reaches the limit of adhesion between wheel and the ground; Wheel generation lateral slip has caused Abnormity abrasion about tyre.
The utility model content:
The purpose of the utility model is the following steering axle that a kind of rational in infrastructure, easy to make, wear on tyres is little, the life-span is long independent air suspension is provided to the prior art weak point.
The purpose of the utility model is to realize through following measure: a kind of following steering axle of independent air suspension, include left and right air bag assembly, and left and right air bag load bearing seat assembly, left and right vibration damper assembly is characterized in that, also has steering swivel system; Said steering swivel system is by left and right track arm; Left and right tierod; Left and right steering damper; Fan-shaped rocking arm, left and right lock-up cylinder is formed, and said fan-shaped rocking arm is connected on the vehicle frame middle position through hinge pin is column articulated; Left and right lock-up cylinder is arranged symmetrically in vehicle frame middle position both sides, its piston rod rod end is articulated and connected on the left and right side arm of fan-shaped rocking arm; Between the left and right side arm and vehicle frame of fan-shaped rocking arm, left and right tierod two ends are articulated and connected between the left and right side arm and left and right track arm of fan-shaped rocking arm through bolted connection at left and right steering damper two ends, and left and right track arm is separately fixed on the left and right steering swivel of taking turns.
Compared with prior art; Adopt the following steering axle of the independent air suspension of the utility model proposition; Has following advantage: control vehicle bridge through the locking of lock-up cylinder with the releasing locking and whether do follow-up steering; Overcome on the one hand when passenger vehicle goes as non-rectilinear and to have produced follow-up bridge Abnormity abrasion about tyre, the service life of having improved tire owing to the motion of three bridges is inharmonious; The third axle of automobile strengthens automobile sports coordination of three in steering procedure as follow-up bridge greatly on the other hand, and the rideability of automobile is fully optimized, and this bridge adopts independent suspension structure simultaneously, has improved car comfort to greatest extent.
Description of drawings:
Fig. 1 is the utility model example structure birds-eye view.
Fig. 2 is Fig. 1 embodiment front elevation.
Fig. 3 is that picture embodiment lock-up cylinder is connected scheme drawing with fan-shaped rocking arm.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1～Fig. 3 has provided the utility model example structure scheme drawing.Among the figure, a kind of following steering axle of independent air suspension includes left and right air bag assembly 1, left and right air bag load bearing seat assembly 2, left and right vibration damper assembly 3, steering swivel system 4; Said steering swivel system is by left and right track arm 41; Left and right tierod 42; Left and right steering damper 43; Fan-shaped Rocker arm 45, left and right lock-up cylinder 46 is formed, and said fan-shaped Rocker arm 45 is articulated and connected on vehicle frame 10 middle positions through hinge pin post 44; Left and right lock-up cylinder 46 is arranged symmetrically in vehicle frame 10 middle position both sides, its piston rod rod end is articulated and connected on the left and right side arm of fan-shaped Rocker arm 45; Between the left and right side arm and vehicle frame 10 of fan-shaped Rocker arm 45, left and right tierod 42 two ends are articulated and connected between the left and right side arm and left and right track arm 41 of fan-shaped Rocker arm 45 through bolted connection at left and right steering damper 43 two ends, and left and right track arm 41 is separately fixed on the left and right steering swivel of taking turns.
The utility model is work like this: when the automobile sport speed per hour surpasses 30km/h, and the automatic locking of lock-up cylinder, each leverage of steering swivel system is lockable, and left and right wheel of steeraxle can't be rotated, and this moment, automobile must be along straight-line travelling.When the automobile sport speed per hour is lower than 30km/h; Lock-up cylinder is removed locking; This moment, each leverage constraint of steering swivel system was disengaged, and the left wheel of steeraxle or right wheel each leverage of follow-up bridge when turning to is made plane motion, can make the effect of another wheel generation follow-up steering.When automobile is done reverse motion, the automatic locking of lock-up cylinder, this moment, automobile must be along straight-line travelling.
The foregoing description does not constitute the restriction to the utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the utility model.
