Abstract

The present disclosure relates to a rubber track unit including: a track main body configured to move by a drive transmitted from a sprocket installed in a vehicle; an elastic part configured to provide a surface pressurized by a road wheel; a support plate to which the elastic part is coupled; and a coupling part detachably coupling the support plate and the track main body so that the elastic part is detachably coupled to the track main body.

First claim

What is claimed is:

1. A rubber track unit, comprising:
a track main body configured to move by a drive transmitted from a sprocket installed in a vehicle;
an elastic part configured to provide a surface pressurized by a road wheel;
a support plate to which the elastic part is coupled; and
a coupling part configured to detachably couple the support plate and the track main body so that the elastic part is detached from or attached to the track main body,
wherein the track main body comprises a cylindrical main body insertion hole for accommodating a connection fixing part, and the connection fixing part is configured to be inserted into each of a connection insertion hole formed in a connection part for connecting the track main body to an adjacent track main body of an adjacent rubber track unit and the cylindrical main body insertion hole formed in the track main body to connect the connection part and the track main body.

2. The rubber track unit of claim 1 , wherein the elastic part is bonded to the support plate through a vulcanization operation.

3. The rubber track unit of claim 1 , wherein the coupling part includes an insertion portion configured to assemble the support plate and the track main body, and a fixing portion coupled to the insertion portion to fix the support plate to the track main body,
the insertion portion is inserted into each of a support coupling hole formed in the support plate and a main body coupling hole formed in the track main body to assemble the support plate and the track main body, and
the fixing portion fixes the support plate to the track main body by pressurizing the support plate toward the track main body.

4. The rubber track unit of claim 3 , wherein the elastic part includes a receiving hole configured to receive the fixing portion,
the receiving hole is formed to have a size larger than that of the support coupling hole, and
the fixing portion fixes the support plate to the track main body by pressurizing a support fixing member surrounding a periphery of the support coupling hole in a state of being received in the receiving hole.

5. The rubber track unit of claim 1 , comprising a pad part disposed to face the support plate with respect to the track main body,
wherein the pad part and the coupling part are integrally formed, and
the coupling part is inserted into each of a support coupling hole formed in the support plate and a main body coupling hole formed in the track main body to couple the support plate and the track main body to the pad part.

6. The rubber track unit of claim 1 , wherein a distance between the coupling part and one side of the track main body is equal to a distance between the coupling part and the other side of the track main body with respect to a width direction.

7. The rubber track unit of claim 1 , wherein a distance between the coupling part and one side of the track main body is shorter than a distance between the coupling part and the other side of the track main body with respect to a width direction.

8. The rubber track unit of claim 7 , wherein the support plate includes a support main body configured to support the elastic part, a support coupling hole to which the coupling part is inserted, and a locking member protruding from the support main body to be inserted into a locking hole formed in the track main body, and
the support coupling hole is disposed at one side of the support main body, and the locking member is disposed at the other side of the support main body.

9. The rubber track unit of claim 1 , wherein the support plate includes a locking member, and
the locking member is inserted into a locking hole formed in the track main body to form a locking structure.
