    Abstract: A water cooling structure of a reducer and a reducer assembly are disclosed. The water cooling structure comprises a chamber formed by a reducer housing and a cover plate, and the cover plate is fixedly connected to the chamber. The chamber is provided with a water inlet and a water outlet respectively. The chamber is also provided with one or several partition plates on two opposite side walls. The partition plates are arranged in an interdigitating manner and each of the partition plates is connected with only one side wall of the chamber, and there is a gap between the partition plates and the opposite other side wall of the chamber, so as to form an S-shaped water path. The water inlet and water outlet are respectively disposed at both ends of the water path. A plurality of baffles are further vertically provided on the partition plates and side walls of the chamber that are parallel to the partition plates, and the baffles are arranged in an interdigitating manner. The water cooling structure disclosed in the present disclosure is integrated with the reducer housing into one part, and thus has a simple structure, saves space and is convenient to arrange on the vehicle. Moreover, the cooling efficiency is further improved by the above special structure.

    Abstract: An electric drive gearbox assembly with stepped hole positioning is disclosed. Specifically, the electric drive gearbox assembly comprises a first housing, a second housing and a positioning pin. The first housing is provided with a first positioning hole on its connecting surface. The second housing is provided with a second positioning hole corresponding to the first positioning hole. The first housing and the second housing are positioned and connected through the first positioning hole, the second positioning hole and the positioning pin. The first positioning hole and/or the second positioning hole are stepped holes. The stepped hole comprises a guiding section close to an open end of the stepped hole and an engaging section far away from the open end of the stepped hole. An aperture of the guiding section is larger than an aperture of the engaging section. The guiding section is used to guide the positioning pin into the engaging section. In the electric drive gearbox assembly, the first housing can be pre-positioned when assembled with the second housing, and the first housing can be radially adjusted relative to the second housing during pre-positioning, so as to facilitate the positioning and assembly of the first housing and the second housing, and promote automated and batch assembly of the electric drive assembly.
