Brake apparatus for vehicle

1. A brake apparatus for a vehicle, comprising:

a motor section receiving electric power, and generating power;

a power transmission section rotated by driving the motor section;

a pair of pressing units receiving power from the power transmission section and pressing a brake pad;

a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit; and

a caliper housing having installed therein the pressing units,

wherein:

the motor section is mounted to an upper surface of the caliper housing;

the motor section is mounted to the upper surface of the caliper housing while being surrounded by a motor housing;

a motor inserting part which entirely surrounds an outer surface of the motor housing inserted therein is formed on the upper surface of the caliper housing;

the motor inserting part is formed integrally with the caliper housing;

each of the pair of pressing units comprises:

a sun gear section rotated by receiving power from the motor section;

a planetary gear section rotated by being meshed with the sun gear section; and

a piston section pressing the brake pad by being moved toward the brake pad through receiving rotational power from the planetary gear section;

the load transmission unit comprises a pair of ring gear sections; and

each of the pair of ring gear sections is rotatable by being meshed with the planetary gear section.

2. The brake apparatus of claim 1 , further comprising a cover unit detachably coupled to the caliper housing to cover the motor inserting part.

3. The brake apparatus of claim 2 , wherein the cover unit has one end which is coupled to a side of the caliper housing and the other end which is coupled to an opposite side of the caliper housing.

4. The brake apparatus of claim 3 , wherein the cover unit is disposed to be spaced apart from the upper surface of the caliper housing.
