[0021] The utility model discloses the content makes further detailed explanation in combination with specific embodiment:

[0022] As Figure 1 Electronic mechanical brake assembly of asymmetric controller as shown, including caliper assembly 1 and MGU assembly 2, MGU assembly 2 is installed on caliper assembly 1, when brake is installed on the wheel edge, caliper assembly 1 and MGU assembly 2 are located between rim 3 and brake disc 4, wherein, MGU assembly 2 includes speed reducer mechanism component 21 and controller component 22, speed reducer mechanism component 21 is inserted on caliper assembly 1, and speed reducer mechanism component 21 includes first gear 211 and second gear 212, and first gear 211 and second gear 212 are engaged with each other, and the center axis of first gear 211 is not in the center of controller component 22 in the projection of controller component 22, so that controller component 22 is arranged asymmetrically relative to the center axis of first gear 211, when brake is installed on the wheel edge, because the space of vehicle wheel edge is relatively limited, the adjustment and installation of controller component 22 and caliper assembly 1 are very limited, and the asymmetric structure of controller component 22 makes controller component 22 more flexible to be arranged on the wheel edge, avoids the waste of space or the difficulty of arrangement caused by symmetric arrangement, can more effectively utilize the wheel edge space, integrates brake assembly 2 with other vehicle systems, thereby improving the compactness and integration degree of overall arrangement, and moreover, the asymmetric design also helps to reduce the energy loss in transmission process, improves transmission efficiency.

[0023] Among them, the gap exists between the curved surface of caliper assembly 1 and MGU assembly 2 and rim 3, and the design of the gap helps air circulation, provides better heat dissipation conditions for brake assembly 2 and MGU assembly 2, avoids the occurrence of overheating phenomenon, and caliper assembly 1 is completely between rim 3 and brake disc 4, controller component 22 is arranged away from brake disc 4, and controller component 22 is close to the inner wall surface of rim 3, reduces the gap between each other, makes the layout of brake in the wheel edge space more compact, thereby saves the precious space resources, and simultaneously, the design of asymmetric controller component 22 makes the distribution of brake force more flexible and accurate, through the accurate calculation of electronic control unit, the independent control of brake force of each wheel can be realized, thereby improving the stability and maneuverability of vehicle, by reducing the gap between controller component 22 and rim 3, the fault risk caused by loose or damaged parts is reduced.

[0024] Further, the center axis of the first gear 211 and the center axis of the second gear 212 are connected to form a first axis 23 in the projection of the controller assembly 22, and the first axis 23 is not located at the center axis of the controller assembly 22, so that the controller assembly 22 is arranged asymmetrically relative to the first axis 23. Because the space of the vehicle wheel is usually limited, the asymmetric design can more effectively utilize the limited space, avoid the waste of space caused by symmetric arrangement, and make the brake assembly 2 more compactly installed on the wheel edge, which helps to reduce the interference and conflict between components, thereby improving the compactness and reliability of the overall arrangement.

[0025] In order to further alleviate the utilization rate of the wheel edge space, the inner wall surface of the rim 3 is a horizontal surface, and the side of the controller assembly 22 close to the rim 3 is a horizontal surface parallel to the inner wall surface of the rim 3. The design of the horizontal surface makes the controller assembly 22 able to be attached to the inner wall surface of the rim 3 or reduce the gap between the controller assembly 22 and the rim 3, instead of an irregular curved surface, thereby increasing the space occupancy and making the limited space more compact, which cannot effectively and fully utilize the wheel edge space.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
