Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
As shown in Figures 1 to 3, Electric Motor Wheel multi-function test stand, is made up of stand main body, vertical load simulation system, steering and ground simulation system.
Stand main body is the main body frame of whole testing table, for removing and installing Electric Motor Wheel and various sensor, and vertical load simulation system and steering are played support and connection function, mainly comprise base 1, body frame 2, guide rail 16, subframe 10, vehicle wheel frame 22.
Vertical load simulation system mainly comprises motor 5, ball-screw (nut 8 and screw rod 9), lifting jack 3 and triaxial force sensor 23, for applying the load that power is subject in the vertical direction with simulating wheel in the horizontal direction.
Steering mainly comprises worm gear 13, worm screw 18, stub 21 and obliquity sensor 24, for making wheel steering.
Ground simulation system, independent of stand main body, mainly comprises rotary drum 31, torque and speed sensors 34 and dynamometer motor 36, for the moment of inertia of simulated roadway situation and automobile.
Described stand main body is provided with a large-scale base 1, for fixing and support body frame 2; The main body of described body frame 2 is welded into by one piece of vertical plate and one block of leveling board, wherein vertical plate is fixed with lifting jack 3, and leveling board is fixed with motor 5, ball-screw support 7 and guide rail 16 successively on the direction pointing to wheel; The output shaft axis of described motor 5 and described ball-screw support 7 determine leading screw screw rod 9 axis on the same line, all perpendicular to body frame vertical plate, the guiding of described guide rail 16 is also perpendicular to body frame vertical plate.
Described subframe 10 connects on track 16, can move linearly along the guiding of guide rail 16; The main body of described subframe 10 is welded by one piece of vertical plate and leveling board; Subframe vertical plate to be connected pushing cylinder 4 and ball-screw nut 8 towards the one side of lifting jack, and on the same line, the internal diameter of pushing cylinder 4 is greater than the push rod external diameter of lifting jack 3, and pushing cylinder 4 is built with a spring for the axis of pushing cylinder 4 and the axis of lifting jack 3; Subframe level version is fixed with bearing bracket 17 and 2 and endless screw support 19, endless screw support 19 determined worm screw 18 axis direction leads perpendicular to guide rail, and worm screw 18 outside end makes handle shape, is convenient to manual rotation worm screw.
The axis direction of described stub 21 and guide rail 16 directed parallel, the side of stub 21 is connected with subframe 10 by thrust bearing 11, and opposite side is connected with vehicle wheel frame 22 by ring flange 15; Described stub 21 supports by two radial bearings, and the bearing seat 12 and 14 of radial bearing is connected on bearing mounting 17 and 20 respectively; A worm gear 13 described stub is equipped with.
Described vehicle wheel frame 22 is rectangular shaped, in the side being parallel to guide rail 16 guiding, triaxial force sensor 23 and obliquity sensor 24 is housed; Described triaxial force sensor 23 is fixed with wheel fixed head 29, and wheel fixed head is used for stationary hub motor 28 and caliper 26; The layout of described obliquity sensor 24 can ensure that it can measure the inclination angle around stub 21 axis direction.
Vertical load simulation system mode of operation is: if only add static load, just directly loads with lifting jack 3; If the dynamic loading of applying, then first apply a larger static load with lifting jack 3, then export a less dynamic loading with motor 5.Specific implementation is: allow the push rod of lifting jack 3 stretch out, and at leisure with the spring contact in pushing cylinder 4, and then compresses.Under the action of the spring, pushing cylinder 4 promotes subframe 10 (guiding of guide rail 16) movement in the horizontal direction.Subframe 10 promotes stub 21 by thrust bearing 11 and moves together, the vehicle wheel frame be now connected on stub 21 pushes triaxial force sensor 23 and moves together, because wheel fixed head 29 is connected on triaxial force sensor 23, and Electric Motor Wheel is fixed on wheel fixed head 29, so tire will be pressed on rotary drum 31 by Electric Motor Wheel in the horizontal direction, now static load has just loaded, triaxial force sensor 23 will feed back to the size of a horizontal direction static load, suitably regulates lifting jack 3 according to size.When applying dynamic loading, the axle of motor 5 rotates, roller leading screw screw rod 9 is driven to rotate, ball-screw nut 8 moves horizontally, because ball-screw nut is connected on body frame 2, what before its tangential movement will be superimposed upon, lifting jack provided moves horizontally, and has so just synthesized a dynamic loading, triaxial force sensor 23 can feed back to now Electric Motor Wheel and be subject to the situation of load, and control system has more the output of feedack self-regulation motor.
Steering mode of operation is: with the handle of hand dynamic worm screw 18 outer end, worm screw 18 rotates, and then drives worm gear 13 to rotate.Because worm gear 13 is fixed on stub 21, therefore stub 21 also rotates thereupon.Under the effect of ring flange 15, vehicle wheel frame 22 rotates around stub 21, and then driving electric wheel rotates around stub 21, and obliquity sensor 24 can feed back to the corner of now Electric Motor Wheel, more suitably shakes worm screw 18 according to the information that feeds back to and adjust.
During test, first manual traverse system first give CircOlectric to be measured to; To be diverted complete after, vertical load simulation system loads to Electric Motor Wheel to be measured again, when power is little, can realize dynamic steering, after namely loading, still can manual traverse system can rotate by driving electric wheel.
Owing to have employed triaxial force sensor 23, thus can clearly obtain Electric Motor Wheel be subject to when rotated rotary drum 31 to vertical force, side force and longitudinal force.The rotating speed of wheel hub motor 28 can be known, i.e. the rotating speed of Electric Motor Wheel by the controller of wheel hub motor 28.Torque and speed sensors 34 can feed back to the rotational speed and torque situation of rotary drum 31.Dynamometer motor 36 can analog electrical driving wheel running car time moment of inertia.To sum up, this testing table conveniently can test the multiple performance such as driven nature, braking, permanance of Electric Motor Wheel.
The above-mentioned description to embodiment can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
