Problems solved by technology

[0003] The traditional power steering system currently used is generally a hydraulic power steering system. Since the hydraulic pressure requires oil pumps, oil pipes, pressure flow control valves, storage tanks, etc., there are many disadvantages such as a large number of parts and a large space occupation.

Abstract

The invention relates to a frame structure of an electric power-assisted steering controller, which is arranged between a torque sensor and a driving motor in an automobile. The controller body includes three parts: a shell, an electronic controller installed in the shell and a radiation fin in the bottom. The electronic controller consists of three relatively isolated modules which are a micro-controlling module, a power source module and a motor driving module. The three modules are connected with each other in the way of mutual layer-cake. The shell has two parts of an upper box cover and a lower box cover and the two parts are mutually connected to be formed into a whole. The frame structure has the advantages that: the three modules are connected with each other in the way of layer-cake; therefore, the structure is more compact, at the same time the volume of the product is also reduced and the interference among each other is greatly reduced.

Description

technical field [0001] The invention relates to a frame structure of a control device, in particular to a frame structure of an automobile electric power steering controller. Background technique [0002] With the rapid development of modern automobile technology, people's requirements for the steering performance of automobiles are also increasing day by day. It is required that the vehicle should have ideal stability when turning the steering wheel under any circumstances. Therefore, people have installed power steering systems on vehicles. The system effectively improves the sensitivity of the steering, increases the convenience of the driver's manipulation, and does not feel the vehicle is erratic when driving at high speed, thereby improving the safety of the car. [0003] The traditional power steering system currently used is generally a hydraulic power steering system. Since the hydraulic pressure requires oil pumps, oil pipes, pressure flow control valves, storage t...
