Abstract

The present invention relates to a transmission, an in-wheel drive system comprising same, and a method for manufacturing a transmission. One embodiment of the transmission according to the present invention comprises a clutch disk having on one surface a plurality of grooves. Also comprised can be a plurality of driving force transfer bodies, which are inserted into each of the plurality of grooves of the clutch disk, respectively, so that a portion of the driving force transfer bodies are exposed on the one side of the clutch disk.

Description

technical field [0001] The present invention relates to a transmission and a four-wheel drive system for a vehicle including the transmission, in particular to a transmission that is easily miniaturized and can reduce shifting shocks and a four-wheel drive system for a vehicle including the transmission. [0002] In addition, the present invention also relates to a manufacturing method of the transmission. Specifically, the invention relates to a transmission manufacturing method capable of simplifying the manufacturing process of the transmission and improving assembly performance. Background technique [0003] In general, an electric vehicle uses an electric motor driven by a battery as a power source, which is lighter in weight and relatively smaller in size than conventional fossil fuel vehicles or natural gas vehicles. [0004] The important development elements of this kind of electric vehicle include the improvement of driving speed and fuel, the improvement of charg...
