Detailed Description
The core of the present invention is to provide a suspension system capable of effectively improving the running tracking property and the steering stability of a vehicle; meanwhile, a vehicle using the suspension system is provided.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic diagram of a fitting structure of a suspension system according to an embodiment of the present invention; FIG. 2 is a top view of FIG. 1; fig. 3 is a side view of fig. 1.
In a specific embodiment, the suspension system provided by the invention comprises an axle 11 which is arranged below a vehicle body along the width direction of the vehicle and is connected between wheels at two sides, longitudinal supporting rods 12 which extend along the length direction of the vehicle are respectively arranged at two ends of the front side of the axle 11, and shock absorbers 13 are respectively arranged at the tops of two sides of the axle 11 along the height direction of the vehicle; the middle part rear side of axle 11 is provided with lower support arm 111 and upper end articulates in the stabilizer bar 14 of underbody, and the middle part of axle 11 is provided with the hinge 112 that the axis extends along vehicle length direction, and the middle part of stabilizer bar 14 articulates on hinge 112, and lower support arm 111 is located between the one end of axle 11 and hinge 112 along the axial of axle 11, and the lower end of stabilizer bar 14 articulates in the bottom of lower support arm 111.
In the assembly operation process, the stabilizer bar 14 is hinged with the lower support arm 111, the hinge shaft 112 and the vehicle body respectively to form a three-hinge-point coaxial self-locking mechanism, so that when the vehicle runs on a curve or the vehicle jumps, the acting force from the width direction of the vehicle can be converted into the acting force along the height direction of the vehicle under the synergistic effect of the stabilizer bar 14 and the corresponding hinge matching piece, the acting force can be removed only by moderately moving the axle 11 and the vehicle body along the height direction of the vehicle, the transverse displacement or movement trend between the axle 11 and the vehicle body is avoided, the tracking property in the running process of the vehicle is ensured, the vehicle is more stable and controllable, the operation precision is reliable, and the stable and continuous running of the vehicle is ensured.
The longitudinal direction of the vehicle referred to herein refers to the vehicle traveling direction; the width direction of the vehicle referred to herein refers to the extending direction of the axle; the height direction of the vehicle referred to herein refers to a direction perpendicular to the rolling plane of the wheel.
Further, a traction arm 15 extending in the vehicle longitudinal direction is provided on the front side of the axle 11, the traction arm 15 is located between the two longitudinal struts 12 in the axial direction of the axle 11, and the front end portion of the traction arm 15 is hinged to the vehicle underbody. During running of the vehicle, the traction arm 15 is cooperatively matched with the longitudinal brace 12 to bear the acting force and load from the length direction of the vehicle; at the same time, the longitudinal strut 12 cooperates with the stabilizer bar 14 to receive forces and loads from the vehicle width direction; and the force and load in the vehicle height direction are received by the shock absorber 13. The trailing arm 15 is capable of effectively relieving the operating pressure of the longitudinal strut 12, improving the load bearing capacity of the suspension system and optimizing the stress distribution among its components to further improve the overall ride performance of the vehicle.
Specifically, the axis of the trailing arm 15 is collinear with the axis of the hinge shaft 112. The axial line collinear structure can enable the traction arm 15, the hinge shaft 112 and the stabilizer bar 14 to form an interlocking stress relief mechanism so as to further improve the load tolerance and the impact resistance of the middle part of the axle 11, thereby correspondingly improving the overall structural strength and the reliability of the axle 11 and the suspension system and enabling the running process of the vehicle to be more stable and reliable.
More specifically, the front end portion of the trailing arm 15 is hinged to the vehicle body, and each hinge portion of the stabilizer bar 14 is provided with a vulcanized rubber bushing. The vulcanized rubber bushing can effectively avoid structural abrasion of the contact part of each hinge fitting piece caused by direct rigid contact, so that the service life and working condition tolerance of each main part of the suspension system are correspondingly improved.
In a specific embodiment, the vehicle provided by the invention comprises a vehicle body and a suspension system positioned below the vehicle body, wherein the suspension system is the suspension system described in the embodiment.
