Abstract

The invention discloses a double-shift 30-degree redundant steering motor unit, which includes a motor housing, a motor front end cover, a motor rear end cover, a double rotor assembly and a wiring double stator structure, and the front end cover and the rear end cover are respectively The connecting bolts are arranged on the front and rear sides of the motor casing, the stator assembly is arranged inside the motor casing, and the double rotor assembly is embedded in the wiring double stator structure. The wiring double stator structure is provided with four sets of independent windings, of which , The two sets of windings form a group, and the two sets of windings are staggered by an electrical angle of 30 degrees in space. The present invention implements four sets of independent windings. If one set of windings and the drive control circuit of the steering system fail, the remaining three sets of windings can provide at least 75% boost in safety without affecting the driver's control of the steering wheel and fully meet the requirements of automatic driving. Safety requirements.

Description

technical field [0001] The invention relates to the technical field of automobile electric power steering systems, in particular to a double-shift 30-degree redundant steering motor unit. Background technique [0002] Automobile electric power steering system EPS is one of the most important assemblies related to the personal safety of drivers and passengers on the vehicle. Redundant safety design must be considered to ensure that basic and controllable steering capabilities can be provided under any circumstances. Currently, the automotive electric power steering system EPS consists of an electronic control part and a mechanical structure. In the case of failure of the electronic control part of the traditional EPS system, the driver can only drive the steering through mechanical structures such as pipe columns and immediately pull over to stop, which cannot meet higher-level safety requirements such as automatic driving. Contents of the invention [0003] Purpose of the...
