BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ABS motor case having a flow path for preventing leakage of oil,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a technology for forming a flow path for preventing oil leakage from flowing into a motor case so as to prevent leakage of oil into an ABS motor,

ABS (Anti-lock Brake System) is a brake system developed to prevent the wheels from locking when the vehicle is suddenly braked. When the vehicle is running, the same weight is not applied to the four wheels. Therefore, when the vehicle is suddenly braked, a lock-up phenomenon occurs in some wheels, that is, the wheels are locked. In this case, the vehicle slides or sideways so that the driver can not control the direction of the vehicle properly.

In order to prevent this problem, it is necessary to pumping the brake so that the wheel is not locked, and it is ABS that the braking is performed by repeating this pumping operation more than 10 times per second by using an electronic control device or a mechanical device .

The ABS motor includes a housing having a cylindrical shape and an open top, and a housing cover coupled to an upper portion of the housing, and a stator is installed inside the housing. A rotor is provided at the center of the stator in accordance with an electromagnetic interaction with the stator, and the rotor is rotatably supported by a rotating shaft. The eccentric bearing is coupled to the upper end of the rotary shaft, and the eccentric bay ram serves to forward and retract the plunger of the pump to reduce the brake pressure.

In general, a motor is a device for converting electric energy into mechanical energy to obtain a rotational force. The motor is a compressor, a washing machine, a vacuum cleaner, an optical disk player, It is widely used in home electronic products such as computer hard disk drives and industrial devices.

However, the conventional motor is exposed to the oil leakage generated in various internal devices according to the use environment of the mounted device, the use period of the device, etc., and when such leakage flows into the motor, have.

In addition, when the motor is operated, the air is expanded inside the motor at a high temperature and a high pressure. When the motor is stopped, the expanded air is shrunk as the motor is stopped and the wetted air is sucked in. And malfunctions.

More specifically, it is an object of the present invention to prevent a threat from short-circuiting or fire from occurring due to inflow of leakage oil generated in various devices connected to a motor, and to prevent the inflow of humid air into the motor And to improve problems that affect shorting and motor durability.

In order to achieve the above object, an ABS motor case having a flow path forming and sealing for preventing leakage of oil leakage according to the present invention comprises a housing 100 forming a magnet 101 therein; A core 300 mounted on the housing 100 to which the magnet 101 is coupled; A rotating shaft 400 passing through the center of the core 300; A housing cover 110 for shielding the housing 100; And a bearing B connected to the center of the upper portion of the housing cover 110 and the lower portion of the core 300 respectively connected to the rotation shaft 400 with the core 300 interposed therebetween The housing cover 110 further includes a flow path 120 and an air vent 130 for preventing leakage of oil into the motor 1 and a chamber 140.

As described above, according to the present invention, a flow path for preventing leakage of oil is formed to prevent the leakage of leakage oil generated in various devices inside the motor, thereby preventing a short circuit or a fire from occurring. It has the effect of compensating the durability of the motor by preventing the inflow of the wet air during the overheating and cooling process.

FIG. 2 is a photographic image according to an embodiment of the present invention; FIG.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited by the scope of the present invention.

FIG. 1 is an exploded perspective view according to an embodiment of the present invention, and FIG. 2 is a photograph of an actual photograph according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, the ABS motor case having the flow path forming and sealing for preventing leakage of oil leakage according to the present invention is applied to an ABS motor, and includes a housing (not shown) 100); A core 300 mounted on the housing 100 to which the magnet 101 is coupled; A rotating shaft 400 passing through the center of the core 300; A housing cover 110 for shielding the housing 100; And a bearing B connected to the center of the upper portion of the housing cover 110 and the lower portion of the core 300 respectively connected to the rotation shaft 400 with the core 300 interposed therebetween The housing cover 110 further includes a flow path 120 and an air vent 130 for preventing leakage of oil into the motor 1 and a chamber 140.

The conventional motor 1 is configured such that the expanded air inside the housing 100 which has become the high temperature and high pressure state due to the operation of the motor 1 contracts during the cooling process of the motor 1 and sucks the wetted air from the outside, However, the motor 1 of the present invention is capable of smoothly discharging the air inside the housing 100 to the outside by forming the air vent 130, To be introduced.

The air vent 130 is formed to have a minimum width so that unnecessary foreign matter is prevented from flowing into the motor.

In addition, the conventional motor 1 is liable to leak oil which is inevitably generated due to aging or defects of peripheral devices, and is susceptible to shot or fire.

The flow path 120 serves to guide the leakage of oil generated in various devices connected to the motor 1 to the chamber 140 separately formed in the housing cover 110.

Specifically, the chamber 140 may include an adsorbent therein. The adsorbent absorbs leaking oil flowing into the chamber 140, thereby suppressing fluidity of the leaking oil accumulated in the chamber 140 during the operation of the motor 1 Do not spill outside. Since the absorbent material is preferably made of a material such as a nonwoven fabric or a cloth and the material may be easily folded or creased, It is possible to freely insert the adsorbent in an amount enough to be accommodated in the chamber 140 without needing to separately process the adsorbent. Therefore, the adsorbent can be easily replaced.

Meanwhile, the material to be filled in order to maintain watertightness and airtightness of various joints and cracks is generally referred to as a sealing material, and in particular, the elastic sealing material is referred to as a sealant (150). The sealant 150 is applied to the upper portion of the housing cover 110 to prevent leakage of oil into the space other than the chamber 140, such as outside or inside the motor 1.

Accordingly, the flow path 120 can be prevented from leaking out through the sealing process using the sealant 150 and coated with Teflon so as to smoothly flow the leaks remaining in the housing cover 110 to the chamber 140, And the flow path 120 can prevent the flow path 120 from being blocked by the surface of the housing cover 110. In addition, May be formed so as to be oriented in the direction of the chamber 140 so that leakage of the leaking oil to the chamber 140 without being influenced by the remaining portion of the housing cover 110 may be used.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
