Abstract
The suspension system for a trailer is disclosed. The suspension system includes a torsion axle and an air spring operating to accommodate a wide range of a load weight applied to the trailer without any change in ride comfort. The air spring can be adjusted for its pressure inside to cover a heavy load weight, while the torsion axle can have relatively softer spring materials therein to cover a light (and zero) load weight. The air spring and the torsion axle are arranged in series to provide adequate suspension based on the load weight.
Claims20
A suspension system for a trailer comprising:
- a first bracket assembly mounted to a frame of the trailer toward a trailer tail;
- an air spring, one end of which is hingedly connected to the first bracket assembly;
- a second bracket assembly mounted to the trailer frame, wherein another end of the air spring is hingedly connected to the second bracket assembly, and wherein the second bracket assembly is spaced apart from the first bracket assembly;
- a third bracket assembly mounted to the trailer frame toward a hitch coupler, wherein the third bracket assembly is spaced apart from the second bracket assembly;
- and
- a torsion axle extending between a set of trailer wheels, wherein the torsion axle extends through an opening defined on the third bracket assembly,
- wherein the air spring is configured to be controlled such that a pressure inside the air spring is adjustable, and
- wherein the torsion axle is configured to absorb a predetermined load weight applied to the trailer, and the air spring is configured to absorb a load weight higher than the predetermined load weight.
A trailer comprising:
- a trailer frame comprising a hitch coupler and a trailer tail;
- a plurality of wheels connected to a main body;
- and
- a suspension system comprising:
- a first bracket assembly mounted to the trailer frame toward the trailer tail;
- an air spring, one end of which is hingedly connected to the first bracket assembly;
- a second bracket assembly mounted to the trailer frame, another end of the air spring hingedly connected to the second bracket assembly, wherein the second bracket assembly is spaced apart from the first bracket assembly;
- a third bracket assembly mounted to the trailer frame toward the hitch coupler, wherein the third bracket assembly is spaced apart from the second bracket assembly;
- and
- a torsion axle extending between a set of trailer wheels, wherein the torsion axle extends through an opening defined on the third bracket assembly,
- wherein the air spring is configured to be controlled such that a pressure inside the air spring is adjustable, and
- wherein the torsion axle is configured to absorb a predetermined load weight applied to the trailer, and the air spring is configured to absorb a load weight higher than the predetermined load weight.
A vehicle comprising:
- a hitch coupled to a vehicle body;
- and
- a trailer which includes:
- a hitch coupler configured to be coupled to the hitch;
- and a suspension system, wherein the suspension system comprises:
- a first bracket assembly mounted to a frame of the trailer toward the trailer tail;
- an air spring, one end of which is hingedly connected to the first bracket assembly;
- a second bracket assembly mounted to the trailer frame, another end of the air spring hingedly connected to the second bracket assembly, wherein the second bracket assembly is spaced apart from the first bracket assembly;
- a third bracket assembly mounted to the trailer frame toward the hitch coupler, wherein the third bracket assembly is spaced apart from the second bracket assembly;
- and
- a torsion axle extending between a set of trailer wheels, wherein the torsion axle extends through an opening defined on the third bracket assembly,
- wherein the air spring is configured to be controlled such that a pressure inside the air spring is adjustable, and
- wherein the torsion axle is configured to absorb a predetermined load weight applied to the trailer, and the air spring is configured to absorb a load weight higher than a predetermined load weight.
