Electric power steering device of new energy vehicle

Abstract

The invention relates to the technical field of steering systems, in particular to an electric power steering device of a new energy vehicle, which includes steering assist mechanisms, an electric power module and a safety detection module, A steering assist mechanism includes a steering wheel, the steering wheel is connected with a steering input shaft, A rack and pinion steering gear is connected to the steering input shaft, A rack and pinion steering gear is connected with a tie rod, The tie rods are attached to the wheels, the steering input shaft is connected with a reduction mechanism, Aleft side of that speed reduce mechanism is connected with a clutch, A boost motor is connecting to that left side of the clutch, the electric power module comprises an ECU controller, Angle sensor,torque sensor, The safety detection module comprises a fault detection device, a single-chip processor, an alarm and a central control display screen. The invention can solve the problem that the current electric power steering device lacks fault detection and safety early warning, so that the driver cannot find out in time in the driving process, and the safety hidden trouble exists.

Description

technical field [0001] The invention relates to the technical field of steering systems, in particular to an electric power steering device for a new energy vehicle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. [0003] At present, the so-called hydraulic power steering or electric power steering system has been widely used in various vehicles due to the characteristics of convenient control, quick response and low energy consumption. , the practical scope of the elec...
