Abstract
A roll rod for a vehicle includes: a front insulator connected to a powertrain; a rod bracket to mount the front insulator on a front end portion of the rod bracket; a case bracket disposed outside the rod bracket and fastened to a vehicle body; a stopping rubber formed at a rear end portion of the rod bracket and disposed in an inner space defined by the case bracket; and a rear insulator formed between the rod bracket and the case bracket, where the rear insulator is secured to an outer side surface of the rod bracket and an inner side surface of the case bracket. The roll rod enhances an insulation rate against vibration of a powertrain and improves durability while reducing manufacturing costs through the simple structure and application of an extrusion molding method.
Claims20
A roll rod for a vehicle, comprising:
- a front insulator connected to a powertrain;
- a rod bracket configured to mount the front insulator on a front end portion thereof;
- a case bracket disposed outside the rod bracket, the case bracket being fastened to a vehicle body;
- a stopping rubber formed at a rear end portion of the rod bracket, the stopping rubber being disposed in an inner space defined by the case bracket;
- and
- a rear insulator formed between the rod bracket and the case bracket, the rear insulator being secured to an outer side surface of the rod bracket and an inner side surface of the case bracket.
A method of manufacturing a roll rod for a vehicle comprising a front insulator connected to a powertrain, the method comprising:
- forming a rod bracket through extrusion molding, the rod bracket comprising a front mounting portion formed at a front end portion thereof to which the front insulator is mounted;
- forming a case bracket through extrusion molding, the case bracket comprising a vehicle-body-coupling portion to be fastened to a vehicle body;
- placing the case bracket outside the rod bracket such that a rear end portion of the rod bracket is disposed in an inner space defined by the case bracket;
- forming a rear insulator between an outer side surface of the rod bracket and an inner side surface of the case bracket;
- and
- forming a stopping rubber at the rear end portion of the rod bracket disposed in the inner space defined by the case bracket.
