YFRobot 4WD Car Alu, mit Lenkung und
Differential, Kit
A. Assembly
1. Check the list
Before the assembly, please check the list of items to see if there are any missing parts, flawed
pieces, and make sure the parts are complete before installation.
2. Tools
Phillips screwdriver
3. Test
Before installing the chassis, please test whether the steering gear and motor are running
normally, and adjust the angle of the steering gear.
➢
If steering gear centering is not noticed before assembly, rudder angle and program need to
be adjusted later. So before the assembly, it is very important to determine the midpoint of
the steering gear. Here you can download the program to the main board and power the
steering gear to center. The test can also be written in your own code or implemented using
a dedicated steering gear controller.
➢
The motor is a DC geared motor, which can be electrified directly at the two poles of the
motor. By default, the marked red point position is positive pole and the other one is the
negative pole.
4. Specifications of screws
For beginners, it is easy to use the wrong size screw; so before the assembly, be sure to be
familiar with the following contents, which will enable you to install the differential car faster.
➢
M2.5 series screws are used for fixing plastic parts, namely front and rear wheel seats,
differential.
➢
M3 * 6mm screws are used to fix the motor bracket.
➢
M3 * 8mm screws are used to fix the steering gear, steering gear bracket and copper
cylinder.
Assembly Notes:
➢
The front anti-collision cotton needs to be finally installed so that the forward steering
structure can be easily adjusted.
➢
When installing the front steering cup, keep rotation flexible, and the M2.5 * 8mm screws
cannot be fixed tightly.
➢
Pay attention to the installation position of the rear wheel seat, install the seat with marked
R
on the left side and the seat with marked
L
on the right side.
➢
The rear drive shaft shall be fixed to the differential before the wheel seat installation.
