Abstract

A tie rod-type brake booster including a casing provided with a front cell and a rear cell, the front cell and the rear cell sealingly joining to each other, a tie rod caulked to the rear cell through the casing, a reinforcement plate to closely contact an inner surface of the front cell to enhance rigidity of the casing, the reinforcement plate being provided with a through hole penetrated by the tie rod, and a support member formed at a penetration portion of the front cell penetrated by the tie rod to fix the reinforcement plate, wherein the support member comprises a bent portion bent from the penetration portion of the front cell, and a pressing portion perpendicularly extending from the bent portion with respect to an axial direction of the tie rod.

First claim

What is claimed is:

1. A tie rod-type brake booster to produce a large braking force using a small force, comprising:
a casing provided with a front cell and a rear cell, the front cell and the rear cell sealingly joining to each other;
a tie rod caulked to the rear cell through the casing;
a reinforcement plate to closely contact an inner surface of the front cell to enhance rigidity of the casing, the reinforcement plate being provided with a through hole penetrated by the tie rod; and
a support member formed at a penetration portion of the front cell penetrated by the tie rod to fix the reinforcement plate,
wherein the support member is provided with a bent portion bent from the penetration portion of the front cell, and a pressing portion perpendicularly extending from the bent portion with respect to an axial direction of the tie rod, and
wherein the pressing portion presses a front surface of the front cell through a penetration portion of the front cell penetrated by the tie rod.

2. The tie rod-type brake booster according to claim 1 , wherein the bent portion bent from the penetration portion of the front cell has a diameter corresponding to a diameter of the tie rod.

3. A tie rod-type brake booster to produce a large braking force using a small force, comprising:
a casing provided with a front cell and a rear cell, the front cell and the rear cell sealingly joining to each other;
a tie rod caulked to the rear cell through the casing;
a reinforcement plate to closely contact an inner surface of the front cell to enhance rigidity of the casing, the reinforcement plate being provided with a through hole penetrated by the tie rod; and
a support member formed in the through hole to fix the reinforcement plate to the front cell,
wherein the support member is provided with a bent portion bent from the through hole of the reinforcement plate, and a pressing portion perpendicularly extending from the bent portion with respect to an axial direction of the tie rod, and
wherein the pressing portion presses a front surface of the front cell through a penetration portion of the front cell penetrated by the tie rod.

4. The tie rod-type brake booster according to claim 3 , wherein the bent portion bent from the through hole of the reinforcement plate has a diameter corresponding to a diameter of the tie rod.

5. A tie rod-type brake booster to produce a large braking force using a small force, wherein:
a through hole penetrated by a tie rod is formed at a reinforcement plate; and
a penetration portion penetrated by the tie rod is formed at a front cell,
wherein a fixing structure is formed by bending to allow the through hole to pass through the penetration portion to press a periphery of the penetration portion against a front surface of the front cell, and
wherein a pressing portion presses a front surface of the front cell through a penetration portion of the front cell penetrated by the tie rod.
