Description

TECHNICAL FIELD [0001] The present invention relates to a motor winding method for an MOC motor actuator,

The present invention relates to an actuator assembly for an MOC motor that performs an operation of an electronic parking brake, and more particularly, to an actuator assembly for an MOC motor that dramatically reduces vibration and noise of an actuator for an MOC motor, To an actuator assembly for an MOC motor.

Furthermore, by maximizing the above-mentioned excellent vibration and noise attenuation function by modularizing the actuator assembly as a single element, it is possible to attain attenuation of vibration and noise, and to improve the ease of assembly and handling as well as MOC To a motor winding method of an actuator assembly for a motor.

An actuator of an electronic parking brake of an automobile comprises a motor and a power transmission device for operating a friction pad provided on a caliper of a disc brake apparatus when parking.

For example, when the driver presses the parking brake switch, the rotational force of the motor of the actuator is transmitted to the input shaft of the caliper through a power transmitting device such as a decelerating device. By the rotation of the input shaft, the pressure connection sleeve advances, and by advancing the pressure connection sleeve, the piston housing it and the caliper housing move toward each other so that the two friction pads mounted on the piston and caliper housing, So as not to rotate.

Various conventional examples of such an electromagnetic parking brake actuator are disclosed in Korean Patent Laid-Open Publication No. 10-2011-0093061 (hereinafter referred to as Patent Document 1), Laid-Open Patent Publication No. 10-2011-0011038 (hereinafter referred to as Patent Document 2) 10-0819087 (hereinafter referred to as Patent Document 3).

The traditional parking brake was a cable-operated system in which the driver pulls the cable to actuate the friction pad or brake lining.

In place of this, an electronic parking brake actuator known in the prior art, including Patent Documents 1 to 3, is a technique adopted to provide a driver with convenience by operating a parking brake by a motor.

As such, the electronic parking brake provides convenience to the driver, but the car designer is faced with the occurrence of unfamiliar noise and vibration due to the mounting of a new type of device. Therefore, researches for regulating or eliminating such vibration and noise must be accompanied by a high quality automobile which can be trusted by the driver.

For example, in an electronic parking brake actuator, the rotational force of the motor is transmitted to the planetary gear set via the gear transmission or belt power transmission, and the rotation of the output shaft of the planetary gear set causes the input shaft of the caliper to rotate.

In this power transmission process, vibrations, noise, and noise due to collision, friction, backlash or the like between gear tooth surfaces occur due to vibration and noise generated by driving of the motor, and generated vibration and noise propagate out of the housing do.

Further, in a state in which the parking brake is not operated, the vibration generated in the engine of the vehicle is transmitted to the actuator housing to generate a resonance sound. The resonance sound of such an actuator housing, by itself, propagates not only to the ear but also to other elements in the vicinity, which may cause a specific noise that has not been heard before.

On the other hand, in recent automobiles, what is called " modularization " in which various components are assembled in advance as sub-assemblies into a single handling element in terms of ease of assembling and parts procurement, A manufacturing method has been introduced.

If the parking brake actuator is modularized, it is possible to simplify the assembling process, to easily procure and manage the parts, since the motor and the power transmission mechanism are both procured from a single assembled module element. And so on.

However, one of the other purposes of modularizing the actuator is to perform the process of producing and assembling the actuator parts by a specialized company so that the research on quality improvement can be concentrated and carried out.

Since the quality of the actuator includes the quality of vibration and noise mentioned above, it is necessary to research and minimize the vibration and noise, and to research and design the structure for modularization.
