Sheet torsion rod spring structure, vehicle suspension and manufacturing method of sheet torsion rod spring structure

Abstract

The invention discloses a sheet torsion rod spring structure, vehicle suspension and a manufacturing method of the sheet torsion rod spring structure. The torsion rod spring structure comprises two sheet type plate springs and a torsion rod, one end of either of the two sheet type plate springs is fixedly connected with one end of the torsion rod, the other end of either of the two sheet type plate springs is fixedly connected with a spherical hinge lining, the two spherical hinge linings are coaxial, and the central lines of the two spherical hinge linings are parallel with the central line of the torsion rod. The suspension makes up-down translational motion when a vehicle axle jumps, the angular change of a transmission shaft is small, and thus the smooth-going property of a vehicle isimproved. Meanwhile, because a transverse stabilizing rod and a lower longitudinal thrust rod are manufactured into a whole , the sheet torsion rod spring air suspension is simpler and more compact instructure, the suspension is low in weight, and the production cost is low.

Description

technical field [0001] The invention relates to the field of vehicle suspension, in particular to a leaf torsion bar spring structure, a vehicle suspension using the leaf torsion bar spring structure and a manufacturing method of the leaf torsion bar spring structure. Background technique [0002] The traditional truck air suspension structure such as image 3 and Figure 4 as shown, image 3 The suspension guide mechanism is composed of the lower two guide arm assemblies 8 and the upper transverse thrust rod 9. When the axle jumps, it rotates around the center of the guide arm roll lug, and the angle of the transmission shaft changes greatly, especially for 6x4 double drive axles; Figure 4 The suspension guiding mechanism is composed of the lower two longitudinal thrust rods 10 and the upper V-shaped thrust rod, and the lateral stabilizer rod 11 plays an anti-rolling role. The air suspension has complex structure and heavy weight, and the angle of the transmission shaft ch...

[0002] The traditional truck air suspension structure such as image 3 and Figure 4 as shown, image 3 The suspension guide mechanism is composed of the lower two guide arm assemblies 8 and the upper transverse thrust rod 9. When the axle jumps, it rotates around the center of the guide arm roll lug, and the angle of the transmission shaft changes greatly, especially for 6x4 double drive axles; Figure 4 The suspension guiding mechanism is composed of the lower two longitudinal thrust rods 10 and the upper V-shaped thrust rod, and the lateral stabilizer rod 11 plays an anti-rolling role. The air suspension has complex structure and heavy weight, and the angle of the transmission shaft changes greatly during transmission. Large, which in turn affects the ride comfort of the vehicle, leading to problems such as poor ride comfort
