Vehicle suspension system and vehicle with same

Abstract

The invention provides a vehicle suspension system and a vehicle with the same. The vehicle suspension system comprises an axle and an elastic element which is arranged on the axle, wherein a bearing surface on the axle for mounting the elastic element is arranged at a position above the tops of wheels, so that the elastic element is arranged above the tops of the wheels. The vehicle suspension system is preferably a front suspension system, and the axle is preferably a front axle. C-shaped beam structures can be formed on the two sides of the axle respectively, the bearing surface of the elastic element is arranged at the upper ends of the C-shaped beam structures, and the lower ends of the C-shaped beam structures are provided with main pin mounting holes. A large-drop structure can be adopted at the middle section of the axle. According to the vehicle suspension system and the vehicle, the width of a passenger passage and the turning angle of the wheels can be greatly increased, large roll stiffness can be obtained under the condition that no lateral stabilizer bar is arranged, and meanwhile, one-step low floor can be realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle suspension system and a vehicle with the suspension system. Background technique [0002] At present, the known front suspension of automobile is made up of elastic element, damping element, guiding element etc., and elastic element is arranged on the inner side of wheel. [0003] Such as figure 1 and figure 2 As shown, the wheel 53 is installed on the kingpin mounting hole of the front axle 51 through the wheel hub 55, the steering knuckle 56 and the kingpin 54. The damping element 52 is installed on the front axle 51, while the elastic element 57, such as a leaf spring, is installed on the supporting surface of the front axle 51 by a fastener 58, and is arranged on the inner side of the wheel 53, that is, the elastic element 57 is arranged on the left and right sides. Between the wheels 53. [0004] This structure will occupy the lateral space of the front ax...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the elastic element 57 occupies the lateral space inside the wheel, the passenger passage is narrow, and the width dimension B of the passenger passage in a medium-sized city is less than 700mm, the standing area is small, and the passenger passage is poor

[0006] 2. Due to the blocking of the elastic element 57 (such as figure 2 As shown), the front wheel steering angle is small, and the front wheel steering space size D is about 300mm, and the maneuverability is poor

[0008] 4. The front axle of the existing medium-sized city bus has a small drop structure, and the height C of the floor from the ground is greater than 460mm. There is only one step between them, and the height of the step does not exceed 380mm
