Abstract
An electric booster for a vehicle including: a disc holder accommodating a reaction disc, a screw nut rotated in conjunction with an operation of a motor, a screw bolt linearly moved in conjunction with a rotation of the screw nut, a boosting block disposed between the reaction disc and the screw bolt, and contacting a radially outer portion of the reaction disc when the screw bolt moves, a pedal rod contacting a radially central portion of the reaction disc through the screw bolt and the boosting block, a disc holder pressing hole connected to the screw bolt, and disposed to face the disc holder, and a first breakage prevention gap part formed between the disc holder and the disc holder pressing hole.
Claims12
An electric booster for a vehicle comprising:
- a reaction disc;
- a disc holder accommodating the reaction disc;
- a screw nut rotatable in conjunction with an operation of a motor;
- a screw bolt configured to be linearly moved toward the reaction disc in conjunction with a rotation of the screw nut;
- a boosting block disposed between the reaction disc and the screw bolt, and in contact with a radially outer portion of the reaction disc in response to movement of the screw bolt;
- a pedal rod extending through the screw bolt and the boosting block and contacting a radially central portion of the reaction disc;
- a disc holder pressing part connected to the screw bolt, and facing the disc holder;
- and
- a first breakage prevention gap part formed between the disc holder and the disc holder pressing hole at a first set width, and configured to limit an amount of elastic deformation in the reaction disc by the boosting block to the first set width or less,
- wherein the boosting block comprises:
- a bolt inner diameter coupling part fitted into an inner diameter portion of the screw bolt;
- and
- a disc outer pressing part connected to the bolt inner diameter coupling part, disposed to face the radially outer portion of the reaction disc outside the screw bolt, and configured to press the radially outer portion of the reaction disc at the first set width when the disc holder pressing hole is in contact with the disc holder.
