Roll-rod for vehicle
View Patent ↗A roll-rod for a vehicle includes an inner pipe protruding from an end surface of a roll-rod body which penetrates an insulator engaged to a bracket and an end plate may be coupled to a rear side of the inner pipe, a fastening bolt being mounted to fasten the end plate to the inner pipe, wherein the insulator has a supporter inserted into a through-hole formed in the bracket and having a pipe shape, and a first front stopper extended from the supporter and protruding to the front of the bracket, and a first rear stopper extended from the supporter and protruding to the rear of the bracket, wherein the first front stopper, the first rear stopper and the supporter may be integrally molded to be fixedly coupled to the bracket.
1. A roll-rod for a vehicle in which an inner pipe protruding from an end surface of a roll-rod body penetrates an insulator engaged to a bracket and an end plate is coupled to a rear side of the inner pipe, a fastening bolt being mounted to fasten the end plate to the inner pipe, wherein the insulator includes:
a supporter inserted into a through-hole formed in the bracket and having a pipe shape;
a first front stopper extended from the supporter and protruding to the front of the bracket; and
a first rear stopper extended from the supporter and protruding to the rear of the bracket,
wherein the first front stopper, the first rear stopper and the supporter are integrally molded to be fixedly coupled to the bracket;
wherein a plurality of first front stoppers protrude from the supporter and are spaced apart from each other so as to be symmetrical to each other with respect to the supporter and a second front stopper protruding with a length shorter than the first front stoppers in the same direction as the first front stoppers is additionally formed between the first front supporters in front of the supporter; and
wherein a front surface of the second front stopper is mounted to the through-hole formed in the bracket.
2. The roll-rod for a vehicle of claim 1 , wherein a first reinforcing portion protrudes on a front surface of the bracket to support the second front stopper.
3. The roll-rod for vehicle of claim 1 , wherein a plurality of first rear stoppers are spaced part from each other and protrude to be symmetrical to each other with respect to the supporter and are closely contacted with the end plate, and a gap therebetween is gradually narrowed rearwards to form a V shape.
4. The roll-rod for a vehicle of claim 3 , wherein a second rear stopper protrudes between the first rear stoppers to face the end plate.
5. The roll-rod for a vehicle of claim 3 , wherein a second reinforcing portion protrudes on a rear surface of the bracket to support a rear surface of the first rear stoppers.
6. A roll-rod for a vehicle in which an inner pipe protruding from an end surface of a roll-rod body penetrates an insulator engaged to a bracket and an end plate is coupled to a rear side of the inner pipe, a fastening bolt being mounted to fasten the end plate to the inner pipe, wherein the insulator includes:
a supporter inserted into a through-hole formed in the bracket and having a pipe shape;
a first front stopper extended from the supporter and protruding to the front of the bracket; and
a first rear stopper extended from the supporter and protruding to the rear of the bracket,
wherein the first front stopper, the first rear stopper and the supporter are integrally molded to be fixedly coupled to the bracket;
wherein a plurality of first rear stoppers are spaced part from each other and protrude to be symmetrical to each other with respect to the supporter and are closely contacted with the end plate, and a gap therebetween is gradually narrowed rearwards to form a V shape;
wherein a second reinforcing portion protrudes on a rear surface of the bracket to support a rear surface of the first rear stoppers; and
wherein an rear surface of the second reinforcing portion is slanted with a predetermined degree from the bracket so as to support an outer surface of the first rear stoppers towards a center axis of the roll-rod body.
7. The roll-rod for a vehicle of claim 5 , wherein an insertion hole is formed in the supporter and the second reinforcing portion so as to receive the inner pipe therein.
8. The roll-rod for a vehicle of claim 1 , wherein an insertion hole is formed in the supporter so as to receive the inner pipe therein.
9. The roll-rod for a vehicle of claim 1 , wherein the insulator is manufactured by injection molding of foaming a shape by injecting a molten synthetic resin material into a mold, and the insulator is manufactured by insert injection molding of previously inserting a bracket into the mold and integrally injecting the insulator into the bracket.
10. The roll-rod for a vehicle of claim 9 , wherein the end plate is additionally inserted into the mold and the first rear stopper is molded to be bonded to the end plate.
