Problems solved by technology

[0002] During the production of the steering gear, the position of the steering gear rod will be symmetrical left and right, and the rack will be in the middle position. However, in the process of logistics, handling and subsequent vehicle assembly, the steering gear rack will move left and right, resulting in the steering gear being loaded. The rack is not in the middle position, which leads to a series of problems. For example, in the subsequent production line, it needs to increase labor costs and reduce the production speed. After leaving the factory, once a problem occurs, it will increase the difficulty of maintenance, etc.

Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] This application is based on the inventor's understanding and research on the following issues:

[0030] In the steering gear production factory, before the steering gear goes off the assembly line, the position of the steering gear rod will be left and right symmetrical, and the steering gear rack will be in the middle position. During the process, the steering gear rack moved left and right, which resulted in the rack not being in the middle position after the steering gear was installed.

[0031] In order to ensure tha...

Abstract

The invention provides an intermediate position returning system and method for a steering gear. The system comprises an OBD interface and the steering gear, wherein the OBD interface is connected toa diagnostic instrument; the steering gear communicates with the OBD interface to receive instructions sent by the diagnostic instrument, and the steering gear comprises an input shaft, a steering motor, a controller and a rotation angle sensor; and the steering motor is used for driving the input shaft to rotate, the rotation angle sensor is used for detecting the rotation angle of the input shaft, and the controller is used for controlling the steering motor to drive the input shaft to return to the intermediate position of a rack according to the detected rotation angle of the input shaft and the target rotation angle corresponding to the intermediate position of the rack of the steering gear when receiving the first instruction sent by the diagnostic instrument. According to the intermediate position returning system for the steering gear, the input shaft can return to the intermediate position of the rack without affecting the function of the steering gear, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of general machinery, in particular to an intermediate position return system of a steering gear and a method for returning the intermediate position of a steering gear. Background technique [0002] During the production of the steering gear, the position of the steering gear rod will be symmetrical left and right, and the rack will be in the middle position. However, in the process of logistics, handling and subsequent vehicle assembly, the steering gear rack will move left and right, resulting in the steering gear being loaded. The rack is not in the middle position, which leads to a series of problems. For example, in the subsequent production line, it needs to increase labor costs and reduce the production speed. After leaving the factory, once a problem occurs, it will increase the difficulty of maintenance. Contents of the invention [0003] The present invention aims to solve one of the technical p...
