Problems solved by technology

[0004] However, a drawback of a steering device utilizing a lead-by-wire system is that the driver may not be able to properly obtain the steering information required by the driver due to the disconnection of the mechanical connection structure
[0008] However, the mechanism for mechanically restricting the rotation and the mechanism for generating the reaction torque of the steering wheel are installed independently, thereby reducing the efficiency of the unified space of the steering device utilizing the lead wire system

Embodiment Construction

[0026] Exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] The steering device for steering using a lead wire system according to an exemplary embodiment of the present invention may be configured to include: a first motor 1 and a second motor 7, a first planetary gear set PG1 and a second planetary gear set PG2, and a stop mechanism .

[0028] will refer to figure 1 To describe it specifically, first, the first motor 1 and the second motor 7 are connected to the first planetary gear set PG1 and the second planetary gear set PG2 , and thus each motor can provide torque.

[0029] The first planetary gear set PG1 may receive torque from the first electric machine 1 , and may reduce the torque and output the reduced torque to the steering wheel 3 to generate reaction torque required for steering.

[0030] The second planetary gear set PG2 may receive torque from the steering wheel 3 and the second moto...

Abstract

The present invention discloses a steering device for steering using a lead-wire system, the steering device comprising: a first motor and a second motor configured to provide torque; a first planetary gear set configured to receive torque from the first motor And generates reaction torque required for steering; a second planetary gear set configured to receive torque from a steering wheel and a second motor, and variably output a transmission ratio input from the steering wheel according to rotation of the second motor; a stop mechanism , which is configured to limit the maximum steering angle of the steering wheel.

Description

technical field [0001] The present invention relates to motor-driven power steering devices. Background technique [0002] A steering device using a wire system is a steering system that separates a mechanical connection between a steering wheel and driving wheels of a vehicle, and may receive a rotation signal of the steering wheel via an electronic control unit (ECU) and Steering motors connected to the drive wheels are operated to steer the vehicle based on the received rotation signals. [0003] Such a steering device using a lead wire system removes an existing mechanical connection structure of a steering system, and thus has benefits of increasing a degree of freedom of layout, improving fuel efficiency, and removing disturbances reversely input from a steering wheel through configuration of a steering system. [0004] However, a steering device utilizing a lead-by-wire system has a disadvantage in that a driver may not be able to properly obtain steering information...
