Description
Technical field
The utility model relates to a kind ofly uses car in the applied wheeled contest of university student's technical ability contest, particularly relates to a kind of two center impeller type racing car that drives.
Background technology
Mostly that in the competition of university student's technical ability, uses at present, is wheeled driving racing car.The racing car of two-wheel drive-type is because simple in structure, easy to make, and application is the most extensive in contest.The driving mechanism of this racing car is made up of driving wheel and driven pulley, and the motor drives driving wheel rotates, and driving wheel rotates with respect to ground and produces the motion state that power changes car body, and driven pulley is followed body movement, plays supporting and stable car body.The racing car of two-wheel drive-type has two driving wheels.According to the supported at three point principle in the mechanical engineering, driving wheel is arranged in the car body middle part, then generally needs two driven pulleys; Driving wheel is arranged in Vehicular body front or rear portion, then needs a driven pulley at least.
In order to strengthen the stability of body movement; The form of the driving mechanism of most of existing two-wheel drive-type racing car is: two driving wheels are arranged in the left and right sides of car body along same axis direction; Be positioned at the front portion or the rear portion of car body; Two driven pulleys are arranged with two driving wheel homonymies respectively, are positioned at the rear portion or the front portion of car body.The form of this driving mechanism is called as two center impeller type racing cars that drive.Change the velocity of rotation size and Orientation of two driving wheels respectively through two motors, the motion state of control racing car.
Driving wheel changes the motion state of racing car with respect to the power of the rotation generation on ground; Its principle is: electric motor driven wheel rotates with respect to ground; Ground produces and rotation direction adhesive force in the same way in the face of wheel, and simultaneously, ground also produces the frictional force with rotation direction reversed in the face of wheel; The size and the direction of the acceleration of difference that adhesive force and frictional force are subtracted each other decision wheel and whole locomotive body motion, adhesive force be greater than frictional force, and difference is being for just, then car body accelerated motion forward; Frictional force is greater than adhesive force, and difference is for bearing then car body retarded motion forward; Under the static situation that begins to start, difference is for just at car body, and wheel rotates forward, and car body is from static divertical motion, and difference is for negative, and then rotate in the wheel original place, promptly produces skidding, and car body is still kept inactive state.If some driving wheel built on stilts are in vacant state, then this driving wheel loses driving action, and the motion of racing car is in the part runaway condition; If two driving wheels of racing car are built on stilts simultaneously, then the motion of racing car is in runaway condition fully.
Existing two center impeller type racing car that drives, its driving wheel and driven pulley adopt the mode that is rigidly connected, and promptly driving wheel of car body the same side and driven pulley all are fixedly connected on the car body, and the driving wheel of the same side and the motion state of driven pulley are coupled.So-called coupling is meant that driven pulley position at the volley directly has influence on the motion state of driving wheel with moving, to the motion generation interference effect of driving wheel; Equally, driving wheel position at the volley directly has influence on the motion state of driven pulley with moving, to the motion generation interference effect of driven pulley.A typical phenomenon is, when racing car is moved on scraggly ground, upwards lift when very high on the ground that driven pulley is protruded, and the driving wheel of the same side is also driven and upwards lifts.In this case, if the driving wheel that is lifted is in vacant state, then driving wheel loses driving action, thereby causes the motion state of car body out of hand.Situation is similar therewith, and when upwards lift when very high on the ground that driving wheel is protruded, the driven pulley of the same side is also driven and upwards lifts.In this case, if the driven pulley that is lifted is in vacant state, then driven pulley loses the effect of supporting and stable car body, thereby causes the motion state of car body unstable.So, adopt the be rigidly connected racing car of mode of this driving wheel and driven pulley can only be applied to generally that the convex-concave degree is less, the desirable ground of opposed flattened.The racing car of on this desirable ground, moving when the convex-concave degree that receives ground influences, can balance out this influence by means of the elasticity of tire, makes racing car be in controllable state preferably.
This desirable ground only accounts for a very little part in the production of reality and life, most of ground all is that the convex-concave degree is bigger, even has the barrier or the pit of protrusion on the ground.Along with further carrying out of university student's technical ability competition, playing condition will inevitably transform from production and the living environment of laboratory conditions to reality, to be adapted to science and technology to the requirement of producing and the life application transforms.This development trend of university student's technical ability competition proposes the very big market demand to the racing car that can be applied in the actual environment widely.
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, two driving center impeller type racing car that the variation of the height and position up and down of driving wheel and driven pulley did not interfere with each other when a kind of moving was provided.
Technical scheme: in order to realize above purpose, the described a kind of two center impeller type racing cars that drive of the utility model comprise car body, driving wheel, driven pulley and motor; The racing car of said two driving center impeller type also comprises: cantilever A, cantilever B, axletree; Said driving wheel is two, is arranged in the left and right sides of car body respectively along same axis direction; Said driven pulley is two, arranges with two driving wheel homonymies respectively; In the middle part of said axletree is positioned at the bottom of the car body car; Said driving wheel is connected with motor reel on being fixedly connected on cantilever A through the key connected mode, and driving wheel is followed motor and rotated; Driven pulley flexibly connects through cantilever B and axletree.The driving wheel of the same side car body and driven pulley are not fixedly connected on the car body in the utility model; But be linked and packed on the same axletree at car body middle part through cantilever A and cantilever B respectively; When motion, the variation of height and position up and down of driving wheel of car body the same side and driven pulley does not interfere with each other; Avoid generation because of the uneven racing car out-of-control phenomenon that occurs in ground.
