Abstract
A vehicle suspension system can include a pair of torsion spring axles, each having one end connected to a left and right wheels of a vehicle, respectively, and the other end extending in the vehicle width direction to symmetrically face each other, and a connection bracket fixedly connecting the facing other ends of the pair of torsion spring axles, which can be used for ride height adjustment of the rear wheels of the vehicle.
Claims20
A vehicle suspension system comprising:
- a pair of torsion spring axles, each of the pair of torsion spring axles having a first torsion spring axle end connected to left and right wheels of a vehicle, respectively, and each of the pair of torsion spring axles having a second torsion spring axle end extending in a width direction of the vehicle to symmetrically face each other;
- and
- a connection bracket fixedly connecting the facing second torsion spring axle ends of the pair of torsion spring axles,
- wherein a pair of trailing arms extending in a longitudinal direction of the vehicle is connected to the left and right wheels, respectively, each trailing arm having a first end connected to a corresponding wheel and a second end connected to a corresponding torsion spring axle such that the corresponding wheel and the corresponding torsion spring axle are interconnected, and
- wherein each of the pair of torsion spring axles comprises:
- an axle link fixedly connected to each of the pair of trailing arms, respectively, on both sides of the vehicle;
- a torsion bar fixedly connected to the axle link and arranged symmetrically around the connection bracket;
- a polygonal tube disposed to enclose the torsion bar and configured to rotate together with a first torsion bar end of the torsion bar in response to torsion occurring in the torsion bar;
- an axle tube disposed outside of the polygonal tube, with a first axle tube end rotatably coupled to the axle link and a second axle tube end fixedly connected to the connection bracket;
- and
- a damper located between an inner surface of the axle tube and an outer surface of the polygonal tube.
