Embodiment Construction

[0012] The present invention will be further explained below in conjunction with accompanying drawing.

[0013] Such as figure 1 and 2 As shown, the present invention is mainly composed of an electronic power steering system 1 and a split type recirculating ball steering machine 2. The electronic power steering system and the recirculating ball steering machine are relatively independent. The input shaft 6 of the type steering machine 2 is connected by a coupling 7 to transmit torque. The housing of the electronic power steering system 1 forms the mounting flange surface 1 3 and bolt holes through casting. Achieve fastening. The shell of the electronic power steering system 1 is processed with a seam 10, and the split type recirculating ball steering machine 2 is processed with the corresponding journal 9 to realize matching positioning. The coupling 7 is connected by means of splines, keyways, hinges, flanges or couplings.

[0014] The above is only a preferred embodimen...

Abstract

The invention discloses a novel structure of a separated type recirculating ball steering gear electric power-assist steering system. The novel structure of the separated type recirculating ball steering gear electric power-assist steering system mainly comprises two systems which are a recirculating ball steering gear (1) and an electronic power-assist steering system (2). Modularization and independence of manufacturing of the two systems are formed, the two systems are convenient to rapidly combine, the product performances and functions of the two systems after being combined are realized and the novel structure of the separated type recirculating ball steering gear electric power-assist steering system is beneficial for satisfying mounting requirements of small spaces of small-sized commercial vehicles.

Description

technical field [0001] The invention relates to the field of electronic power steering design, in particular to a new structure of a split type recirculating ball steering machine electronic power steering device. Background technique [0002] At present, the electronic power steering system is mainly divided into four types according to the installation space and assembly environment of the vehicle: column type electronic power steering system, recirculating ball type electronic power steering system, rack and pinion type electronic power steering system, and rack direct drive electronic power steering system. kind of form. Except for the column-type electronic power steering system, the other three forms are all designed in the steering gear and electronic power steering system. Manufacturers are required to have the ability to produce both steering gear and electronic power steering system, and the threshold is relatively high. At present, there are many suppliers in the...
