Abstract: A cooling structure includes a housing having a cooling channel defined therein through which a coolant flows and includes a sealing cap fitted to a hole of the housing to seal the hole. The sealing cap includes a blocking member configured to be in contact with an internal surface of the housing. The cooling structure may be for cooling a motor, such as an in-wheel vehicle motor.

Abstract: A channel structure includes a cooling channel continuously formed inside a housing. A coolant is configured to flow in the cooling channel. The cooling channel includes a plurality of channel portions spaced apart from each other and extending in the housing by changing directions.

Abstract: The present disclosure provides a sealing device and an in-wheel motor including the sealing device. The in-wheel motor includes a stator, a rotor rotatably disposed with respect to the stator, an annular inner seal connected to the stator and spaced apart from the rotor by a predetermined gap so as to be disposed between the stator and the rotor, and an annular slinger coupled to an end portion of the rotor, wherein the annular inner seal seals between the slinger and the in-wheel motor.

Abstract: A method and a system for sensing engine oil deterioration are disclosed. The method includes measuring an engine RPM, load (Load), and an engine temperature (Temp), calculating the amount of change in a deterioration factor (f (RPM, Load, Temp) of engine oil per revolution of an engine using the measured engine RPM, load, and the engine oil temperature, and then calculating the engine oil deterioration degree at a current time point by accumulating a value obtained by multiplying the calculated amount in change of the deterioration factor (f (RPM, Load, Temp) by an engine revolutions during a predetermined sampling cycle (?r) to a previous engine oil deterioration degree.

Abstract: An oil gel capsule includes an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel. A contact part for a vehicle includes an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules including an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel.

Abstract: The present disclosure relates to manufacturing oil gel capsules and adding the same to an overlay layer of a contact part for a vehicle. The present disclosure may provide a method for manufacturing oil gel capsules and a method for manufacturing a contact part for a vehicle, including the oil gel capsules. The oil gels in the oil gel capsules manufactured by the present disclosure may respond to the temperature environment of a contact part for a vehicle, and an aggregation phenomenon of gelators or an aggregation phenomenon of surfactants may not occur even after an oil is released. Therefore, as oil gel capsules are added to an overlay layer, the present disclosure may improve low friction characteristics and seizure resistance characteristics of a contact part for a vehicle without any side effects caused by the above-described aggregation phenomenon.
