Gear system

Abstract

A gear system is disclosed. The gear system has a structure in which oil churned by a gear is dispensed to at least one of a hollow space or a bearing, thereby effectively lubricating components. For example, the gear system includes a first shaft comprising a hollow space, a first gear arranged at an outer circumference of the first shaft, a second gear externally engaged with the first gear, a bearing arranged at the outer circumference of the first shaft, a housing surrounding the first gear and the second gear, and an oil guide plate disposed between the first shaft and the housing to dispense oil churned by the second gear to the hollow space of the first shaft and the bearing coupled to the first shaft.

Description

technical field [0001] The present disclosure relates to a gear system, and one specific embodiment relates to a gear system having a lubricating structure. Background technique [0002] Typically, vehicles are able to control the rotational speed or rotational force of the wheels using a gear system such as a transmission or a reducer. Cars need to supply lubricating oil to the components of the gear system (such as gears, bearings, etc.) to minimize wear, noise or heat generation of the components. In this regard, in order to lubricate these components, a separate oil pump is generally installed in the related art and driven to supply oil to places requiring lubrication by using the power of the oil pump. [0003] In recent years, there has been an increasing demand for electric vehicles that use electricity or both electricity and petroleum as power sources instead of internal combustion vehicles that use petroleum that causes pollution. [0004] Such an electric vehicl...

However, the maximum charging capacity and energy efficiency of batteries are rather limited, so the maximum distance traveled by electric vehicles must be maximized by reducing the weight of electric vehicles
