Rise, to realize the folding of vehicle body.
Further include four groups of mutually independent wheel steering mechanisms 7, four groups of wheel steering mechanisms are formed with four wheels respectively
Driving turns to connection one by one.On the one hand steering when automobile normal running can be achieved in four groups of wheel steering mechanisms, on the other hand
Also pivot stud of the automobile when parking folds can be realized.
For the Steering of electric vehicle, following mask body parameter designing illustrates:
Electric vehicle deflection angle of inboard wheel in turning is 40 °, and the wheelbase of trolley is set as 1860mm, front tread and
Rear tread is set as 1307mm, and in conjunction with attached drawing 8, it is 3984.44mm to obtain min. turning radius.
Since it is considered that 360 ° of electric vehicle original place can be allowed to rotate, so when electric vehicle rotates in situ, four wheels
Can there be certain deflection angle.Then electric vehicle is rotated in place when folding, then only needing to make in the vertical view of four wheels
Heart line and certain radius circle that the center of circle is rotation center are tangent.It is calculated by design geometry and turns to schematic diagram shown in Fig. 9.
It can be seen that for front-wheel, the amount of deflection of tire is 40 ° when due to turning to, and the corner of front-wheel is when rotating
36.3 °, do not interfere as long as being understood that when front-wheel spatially meets steering, then will not rotatably interfere, and trailing wheel
Space is reserved when then needing exclusively for rotation to prevent vehicle frame, shell and the interference of wheel.
Above-mentioned wheel steering mechanism is further preferably using such as lower structure:
Every group of wheel steering mechanism includes steering motor 7-1, the track rod 7-2 and knuckle of axial stretching can be achieved
The both ends of 7-3, track rod are connect with one end of the output end of steering motor and knuckle respectively, the other end of knuckle with
Corresponding suspension connection, steering motor are installed on corresponding vehicle frame.Specifically, steering motor uses stepper motor, stepping electricity
It is with externally threaded Tiebar structure, track rod and step that machine output shaft, which uses tapped hollow shaft, track rod,
Stepper motor output shaft is connected through a screw thread, the both ends of knuckle respectively with the one end of track rod far from stepper motor and suspension
Formation is hinged, in this way, after steering motor startup, the axial direction of track rod is realized in the cooperation connected by internal and external screw thread
It is flexible, to be deflected by knuckle band motor car wheel, realizes and turn to.The operation principle of steering mechanism is referring to attached drawing 7.
Aforementioned four suspension further preferably uses double wishbone suspension structure.Since the electric vehicle of design is mainly directed to
Urban pavement is not very high to certain parameter requests of suspension when suspension is selected because urban pavement is flatter, so
The suspension of low resistance coefficient, big rigid spring and shorter bump travel may be used, therefore selected double wishbone suspension structure.
This scalable traveling driving for moving up formula miniature electric automobile can refer to the traveling driving of existing electric vehicle.Than
Such as, two drive form of rear wheel drive can be used, driving motor and differential deceleration device are symmetrically arranged in Rear frame;Wheel hub can be used
Motor directly drives etc..
The bases such as this scalable traveling driving motor for moving up formula miniature electric automobile, the battery powered to motor and controller
This component parts is arranged according to specific design conditions in front frame or Rear frame.
Electric car body is divided into three changeless parts of volume by the technical program, by adjusting vehicle body three parts
Relative position change the length of vehicle body, need not thus consider in sealing problem and vehicle body of the vehicle body in telescopic process
Top plate, floor and gusset telescoping problem, so that problem is become simple.In addition realize that trolley is stayed using four deflecting rollers in this programme
Pivot stud problem when vehicle, it is zero that can make the turning radius of trolley in theory, and still uses preceding rotation in driving
To form, the driving habit of driver will not be changed.
