Detailed description of the invention
Below with reference to the accompanying drawings embodiments of the invention are described.
With reference to Fig. 1, driving cabin comprises front cabin structure 101 and structure of rear cabin 110.Front cabin structure 101 inside is provided with seat 103 and operation display device 102, realizes the simulated operation of the various equipment such as simulated aircraft, naval vessel and vehicle.According to the present invention, both can rotate and oscilaltion slip along the rotation of 360 degree, transverse axis, the longitudinal axis 360 degree by control cabinet body separately, also can control this three degree of freedom simultaneously and carry out compound motion, simulate various driving equipment moving realistically, the impression of continuous continual centrifugal force overload is provided.
Driving cabin is arranged on support 111 via transverse axis 113,114.As shown in Figure 2, support about 111 each is arranged symmetrically with, and right side is provided with motor-driven lead screw mechanism 118 and guide rail 117, and left side is provided with motor-driven lead screw mechanism 120 and guide rail 119.Right horizontal axis 114 is connected with guide rail 117 via right side bearing spider 115, and left horizontal axis 113 is connected with guide rail 119 via left side bearing spider 112.Complete Synchronization control is carried out by the drive motors of the drive motors of the feed screw apparatus 120 to left side and the feed screw apparatus 118 on right side, and then the lifting of control cabinet body.The purposes of lifting can be used for facilitating occupant to come in and go out, and also can be used for expanding to the skimulated motion driving cabin body to do above-below direction.In addition, lifting structure described here is a kind of example, except adopting the mode of above-mentioned lead screw transmission, can also be realized by modes such as rack-driving, chain drive, toothed belt transmission, cog belt transmission, rope traction transmission, hydraulic drives.
Motor 116 is connected with right side bearing spider 115, and the output shaft of motor 116 is connected with right horizontal axis 114, and right horizontal axis 114 is connected with right side bearing spider 115 by bearing, and opposite side and the transmission case 105 of right horizontal axis 114 are connected and fixed; Left horizontal axis 113 is connected with left side bearing spider 112 by bearing, and the opposite side of left horizontal axis 113 is also connected and fixed with transmission case 105; Transmission case 105 is fixed with structure of rear cabin 110.The outputting power of motor 116 is delivered to right horizontal axis 114 via output shaft, and then is delivered to transmission case 105, and before driving thus, cabin structure 101 and structure of rear cabin 110 rotate along transverse axis 113,114, and left horizontal axis 113 is servo-actuated.Like this by controlling the pitch rotation of 360 degree that the rotation of motor 116 just can drive front cabin structure and structure of rear cabin to carry out along transverse axis.During pitch rotation, front cabin structure 101 and structure of rear cabin 110 synchronous axial system, between the two without relative motion.
With reference to Fig. 1, motor 107 is arranged on the rear end of transmission case 105, and the output shaft of motor 107 is connected with the longitudinal axis 104, and the longitudinal axis 104 is connected with transmission case 105 by bearing spider, and the front end of the longitudinal axis 104 and the rear end of front cabin structure 101 are fixed.The outputting power of motor 107 is delivered to the longitudinal axis 104 via output shaft, and then is delivered to front cabin structure 101, and before driving thus, cabin structure 101 rotates along the longitudinal axis 104.Rotation like this by controlling motor 107 just can drive front cabin structure 101 to carry out rotating along the roll of 360 degree of the longitudinal axis.When roll is rotated, structure of rear cabin 110 is without rotation, and front cabin structure 101 relatively rotates for structure of rear cabin 110.
As shown in Figure 1, front cabin structure 101 has certain distance apart from the axle center 121 of transverse axis 113,114, the pitch rotation of front cabin structure 101 can be caused so eccentric relative to the axle center 121 of transverse axis, there is the larger radius of gyration, make occupant obtain very strong centrifugal overload sensation, and provide the overload of larger centrifugal force and angular acceleration to experience.
Electric threaded shaft 108, guide rail 109 are fixed with structure of rear cabin 110, and trim assembly 106 is connected with guide rail 109, and electric threaded shaft 108 drives trim assembly 106 along guide rail 109 slide anteroposterior.By the distance of adjustment trim assembly 106 with the axle center 121 of transverse axis 113,114, realize the difference of the mass M 2 at the mass M 1 in front, transverse axis axle center 121 and the product of barycenter radius R 1 and rear, transverse axis axle center 121 and the product of barycenter radius R 2 within the scope of the threshold value T allowed: | M1 × R1-M2 × R2|<T.When the passenger of different weight is taken, automatically the mass change of front cabin structure 101 is detected by sensor, according to the testing result of sensor, controlling electric threaded shaft 108 drives trim assembly 106 along guide rail 109 slide anteroposterior, thus realizes automatic trim, and balance mass changes, the rotating load of reduction system and rotary inertia, ensure to rotate at a high speed, steadily, and then realize high-speed rotation, and provide the overload of larger centrifugal force and angular acceleration to experience.
