## Abstract

A suspension for a vehicle may include: a main frame; a lower leaf spring installed on either side of the main frame; an upper leaf spring disposed above the lower leaf spring so as to be spaced apart from the lower leaf spring; a connection bracket supported by the upper leaf spring, and rotatably mounted on the main frame; an eye clip mounted on an end portion of the lower leaf spring, and connected to a wheel; and a rubber bush mounted on either side of the upper leaf spring, and connected to a vehicle body.

## Claims

### Claim 1

A suspension for a vehicle, comprising:
a main frame;
a lower leaf spring installed on either side of the main frame;
an upper leaf spring disposed above the lower leaf springs so as to be spaced apart from the lower leaf springs;
a connection bracket supported by the upper leaf spring, and rotatably mounted on the main frame;
an eye clip mounted on an end portion of the lower leaf springs; and
a rubber bush mounted on either side of the upper leaf spring.

### Claim 2 (depends on 1)

The suspension of claim 1, wherein the lower leaf spring comprises:
a first lower leaf spring installed on one side of the main frame; and
a second lower leaf spring spaced apart from the first lower leaf spring, and installed on another side of the main frame,
wherein the main frame comprises:
a first main frame on which the first lower leaf spring is installed; and
a second main frame having one side which is link-connected to the first main frame and another side on which the second lower leaf spring is installed.

### Claim 3 (depends on 2)

The suspension of claim 2, wherein the connection bracket comprises:
a connection bracket body configured to surround an outer surface of the upper leaf spring;
an extension extended from the connection bracket body toward the main frame; and
a pin configured to connect the extension, the first main frame, and the second main frame.

### Claim 4 (depends on 2)

The suspension of claim 2, wherein the first lower leaf spring and the second lower leaf spring have a curved shape so as to be elastically deformable.

### Claim 5 (depends on 1)

The suspension of claim 1, wherein the upper leaf spring has a curved shape so as to be elastically deformable.

### Claim 6 (depends on 1)

The suspension of claim 1, wherein the eye clip comprises:
an eye clip body part connected to the wheel; and
an eye clip accommodation part concavely disposed at an end portion of the eye clip body part, and configured to accommodate the lower leaf spring.

### Claim 7 (depends on 1)

The suspension of claim 1, wherein the rubber bush comprises:
a rubber bush bracket mounted on an end portion of the upper leaf spring;
a rubber bush column passed through the upper leaf spring, and mounted on the rubber bush bracket;
a rubber bush cover mounted on an outer surface of the rubber bush column; and
an elastic part interposed between the rubber bush cover and the upper leaf spring, and elastically deformed by the upper leaf spring.

### Claim 8 (depends on 7)

The suspension of claim 7, wherein the elastic part is made of rubber.

### Claim 9 (depends on 1)

The suspension of claim 1, wherein the eye clip is made of aluminum.

### Claim 10 (depends on 1)

The suspension of claim 1, wherein the eye clip is configured to be connected to a wheel.

### Claim 11 (depends on 1)

The suspension of claim 1, wherein the rubber bush is configured to be connected to a vehicle body.
