Therefore, the hinges 250 may smoothly rotate and prevent an excessive load to a slope adjust unit 120 to be described below. Heights of the hinges 250 are determined to be equal to or close to the height of the seating surface to similarly simulate a variation of the slope depending on an inclination of the ground surface during actual traveling.

bike simulator 20 according to the present invention is configured to include abase frame 100, aslope frame 200, aroll frame 300, afront wheel support 400, arear wheel support 500, ahydraulic power unit 610, and a sensor unit (not illustrated) and may be configured to be used by seating various types ofbikes 10. And it showed only the frame and the wheels of the bike, for convenience of description and is omitted with respect to remaining components of the bike. - The
base frame 100 wholly supports thebike simulator 20 and is configured to be joined with other components. Thebase frame 100 may be configured in a height so as for seating surfaces which are surface on which two wheels of thebike 10 are seated to be spaced apart from a ground surface by a predetermined distance when thebike 10 is fixed. In detail, thebase frame 100 may be formed at an appropriate height so as not to be shocked by contacting a floor even when theslope frame 200 is inclined at a limit angle. Thebase frame 100 may be configured in a shape to stably support thebike simulator 20 by considering a center of gravity and inertial force when thebike simulator 20 is inclined in a tilting back and forth or left and right while thebike 10 is seated. Thebase frame 100 may be configured in a symmetric shape so as to stably support thebike simulator 20 at the time of applying the slope in both directions when thebike 10 is seated. Therefore, when thebike 10 is set, left and right sides may be symmetrically configured. Meanwhile, thebase frame 100 may be configured to include a plurality ofstairs 110 so that the user easily rides on thebike 10 seated at a predetermined height. Meanwhile, a shape of the illustratedbase frame 100 is one example and may have various shapes to stably support thebike simulator 20. - The
bike 10 is set on theslope frame 200 and is configured to apply a longitudinal slope of thebike 10 while thebike 10 is set. The top surface of theslope frame 200 may be substantially flatly configured so as to simulate the ground surface and a space is formed providing components including a vibration generating unit, a slope adjustunit 120, and the like to be described below may be formed inside theslope frame 200. Further, a rotational inertial moment is preferably minimized for rapid reaction of the simulator and further, weight reduction is preferable. - The
slope frame 200 is comprising the seating surface which isseating bike 10 and is configured to fix a frame of thebike 10 while thebike 10 is seat. Accordingly, when theslope frame 200 itself is tilted in the longitudinal direction, thebike 10 is also inclined together. That is, a relative rotational angle of theslope frame 200 with thebase frame 100 varies to control a pitch of the seatedbike 10. - The
slope frame 200 may be rotatably connected to thebase frame 100. Theslope frame 200 is positioned at the center of thebase frame 100 and even when theroll frame 300 to be described below is tilted in the width direction, thebase frame 100 may stably support theslope frame 200. In this case, theslope frame 200 has a pair ofhinge 250 provided at both sides thereof to be connected with thebase frame 100.

In detail, the longitudinal location may become a location adjacent to a rear wheel rather than a front wheel by considering weights of components such as theroll frame 300 which is positioned in the rear of the slope frame(200) to be described below when thebike 10 is set. Therefore, thehinges 250 may smoothly rotate and prevent an excessive load to a slope adjustunit 120 to be described below. Heights of thehinges 250 are determined to be equal to or close to the height of the seating surface to similarly simulate a variation of the slope depending on an inclination of the ground surface during actual traveling. - The slope of the
slope frame 200 may vary by actuating the slope adjustunit 120. In this case, one side of the slope adjustunit 120 is connected to theslope frame 200 and the other side of the slope adjustunit 120 is connected to thebase frame 100. Therefore, theslope frame 200 may be inclined forward or rearward around thehinge 250 according to a stroke of the slope adjustunit 120. In this case, the slope adjustunit 120 is constituted by a linear actuator and the slope adjustunit 120 may be connected to a location which is a middle point of the stroke while theslope frame 200 being flat. Therefore, as the stroke of the slope adjustunit 120 is actuated around the middle point, an inclination direction and an inclination angle of the slope adjustunit 120 may vary. However, the constitution of the slope adjustunit 120 is one example and may be modified and applied in various constitutions in which the slope may be applied to theslope frame 200, which include a rotary actuator, and the like. -

That is, a roll of thebike 10 is controlled and in detail, the roll is controlled around a rotary axis. - The
roll frame 300 may be configured to rotate at a predetermined angle together with thebike 10 with a connected point with theslope frame 200 as a rotation axis so as to apply a tilting left and right—the width direction slope—the bike. In this case, the rotation axis may be a axis including a front-wheel contact point and a rear-wheel contact point on the seating surface so as to similarly simulate a horizontal motion of thebike 10 during the actual traveling. In this case, a motion which thebike 10 is tilted left and right based on contact points of an actual tire may be simulated. In this case, therotary actuator 350 may be provided to generate the tilting left and right. Therotary actuator 350 may be provided at a location coaxially with a rotary center of theroll frame 300.

That is, when an ascending road is simulated, the slope frame is inclined rearward and theload generating unit 510 generates reverse torque to control force required for traveling to increase. On the contrary, when a descending road is simulated, since a velocity of theactual bike 10 increases due to gravity, the torque required for the traveling decreases, and as a result, theslope frame 200 is inclined forward and theload generating unit 510 generates forward torque. - A rolling
