Abstract

The invention discloses a split type steering engine which comprises an upper shell structure, the upper shell structure comprises a first cavity used for containing an input and output shaft system assembly; a second cavity which is formed in the side wall of the first cavity, communicates with the first cavity through a connecting window and is used for containing the worm assembly; a lower shell structurewhich comprises a third cavity formed in a fourth cavity, the upper end of the third cavity is used for being connected with the first cavity, and the lower end of the third cavity communicates with the fourth cavity; a fourth cavity which is used for allowing a rack bushing and a rack to penetrate through; the first fixing structure is formed on the third cavity beside the fourth cavity and is used for connecting and fixing an auxiliary frame; wherein the steering engine input and output shaft system assembly and the worm assembly are in meshing transmission through the connectingwindow, and the input and output shaft system assembly transmits an input steering source to the worm assembly and the rack. The steering engine is designed to be of a split structure, mold strippingis easy, modular production and assembly can be achieved through the split structure, subsequent maintenance is facilitated, and the production cost of the steering engine is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a P-EPS split steering gear. Background technique [0002] The electric power steering system is developed on the basis of the traditional mechanical steering system. The electric power steering system uses the power generated by the electric motor to help the driver perform the steering operation. The system is mainly composed of three parts, the signal sensing device, the power steering mechanism and the electronic control device. [0003] Generally speaking, according to the structure, it can be divided into three types: C-EPS, P-EPS and R-EPS. This application mainly relates to the split type steering gear of P-EPS. P-EPS is Pinion EPS, pinion type EPS, also called pinion type EPS, the motor is applied to the rack through the pinion, that is, the steering column and the motor are parallel in the same mechanism (such as ball screw or circulating ball) Coupled to the rack; the bas...
