AI Technical Summary

Technical Problem

The prior art provides components such as brackets and fixing frames in vehicle braking systems, resulting in a large number of parts, complex installation processes and large volumes.

Method used

The housing adopting an integrated shaped structure includes a first cavity, a second cavity and an intermediate cavity for accommodating a motor, a planetary gear transmission mechanism and other transmission mechanisms, reducing dependence on the bracket and the fixing frame.

Benefits of technology

It has achieved savings in the number of parts, simplified installation processes and reduced volume, and is especially suitable for passenger cars with limited chassis space.

Abstract

The invention discloses an execution unit of an electronic mechanical brake. Comprising a motor, a driving side transmission mechanism connected with a motor shaft, a middle transmission mechanism connected with the output end of the driving side transmission mechanism, a driven side transmission mechanism connected with the output end of the middle transmission mechanism, a planetary gear transmission mechanism connected with the output end of the driven side transmission mechanism, and a shell of an integrally formed structure. The first cavity is used for accommodating a motor, the second cavity is used for accommodating a planetary gear transmission mechanism, and the middle cavity is used for accommodating a driving side transmission mechanism, a middle transmission mechanism and a driven side transmission mechanism; an end cover is arranged on the second side of the middle cavity, one end of a shaft of the driving side transmission mechanism, the middle transmission mechanism and the driven side transmission mechanism is supported on the end cover, and the other end of the driven side transmission mechanism is supported on the second cavity through a shaft. The internal structure of the shell is compact, space is effectively utilized, components such as a bracket and a fixing frame do not need to be arranged, the number of parts is reduced, and installation procedures are simplified.
