Abstract
An apparatus for generating a road surface reaction force in a test apparatus for a steer-by-wire system includes a steering actuation unit, and actuators arranged in parallel to tie rods of the steering actuation unit. In accordance with this arrangement, there is an advantage of a reduced installation space. Also, it is possible to transmit the force of each actuator to the associated tie rod without loss, and thus, to accurately implement the generation of a road surface reaction force.
Claims6
An apparatus for generating a road surface reaction force in a test apparatus for a steer-by-wire system, comprising:
- a steering actuation unit comprising a tie rod;
- an actuator arranged in parallel to the tie rod of the steering actuation unit;
- a connector which connects the tie rod of the steering actuation unit to the actuator;
- a first sliding member, which linearly moves the connector in a forward or rearward direction in accordance with an operation of the actuator, coupled to the connector at a first side;
- a second sliding member, which linearly moves the connector in the forward or rearward direction in accordance with the operation of the actuator, coupled to the connector at a second side;
- a first guide rail that guides a movement of the first slider;
- and
- a second guide rail that guides a movement of the second slider;
- wherein the first and second guide rails are substantially parallel, such that the movements of the first and second sliders are substantially parallel.
