The present invention relates to an electric brake apparatus, and more particularly, to an electric brake apparatus that improves the operation reliability of the device by preventing loosening of the drive gear for operating the brake pad.

In general, a brake system is a brake device used to perform an operation of decelerating or stopping a driving vehicle or to maintain a parking state.

Such a brake system typically uses a friction type brake that converts kinetic energy into thermal energy using friction force and releases it into the atmosphere to brake.

The friction brake uses a hydraulic brake that performs a braking function as the brake pad is pressed by hydraulic pressure on both sides of the disk rotating together with the wheels. Brake) is used.

In the electric brake, when the ECU receives the electronic pedal information during braking to drive the motor to generate axial rotational force, the piston is axially moved through the reducer coupled to the motor to press the disk with the brake pad to implement braking.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

In the electric brake apparatus, the lever is inserted into the thread formed on the outer surface of the drive gear to prevent the drive gear from loosening. However, since the restraint position of the drive gear is determined according to the thread spacing, the operation reliability is lowered. Therefore, there is a need for improvement.

The present invention has been made by the necessity as described above, an object of the present invention is to provide an electric brake apparatus that can improve the operation reliability by determining the restraint position of the drive gear irrespective of the shape of the thread.

The electric brake apparatus according to the present invention comprises: a gear portion for transmitting power for operating a brake pad, a support portion spaced apart from the gear portion, and a locking portion drawn into a space formed between the gear portion and the support portion to restrict rotation of the gear portion. Include.

In addition, the gear unit preferably includes a drive gear connected to the drive motor.

Moreover, it is preferable that a support part contains a roller member.

In addition, the locking unit preferably includes a driving member for supplying power and a locking rod reciprocated in connection with the driving member.

In addition, it is preferable that the driving member uses a solenoid.

In addition, the lock rod is preferably formed in a wedge shape.

The electric brake apparatus according to the present invention is provided with a support part spaced apart from the drive gear, and inserts a wedge-shaped lock rod between the drive gear and the support part to restrict the rotation of the drive gear, thereby preventing the brake pad from loosening. Reliability can be improved.

Hereinafter, an embodiment of an electric brake apparatus according to the present invention will be described with reference to the accompanying drawings. For convenience of description, an electric brake device used in an automobile will be described as an example. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.
