5. Terminology

2WD, 4WD
2-wheel drive or 4-wheel drive
ABC action settings
ABC stands for aluminium, brass and chrome. Aluminium with its low thermal expansion and small weight serves as material for pistons, the cylinder is made
of brass with chrome-plated contact surface.
Axle leg
This is where the axle turns. The steering levers are located on the front axle legs.
Steering knuckle pin
Steering axle of the wheel. Connects the axle leg with the axle leg support so that it can be turned (between the top and bottom transverse link).
Spindle
The axis onto which the wheel is screwed and around which the wheel is turning.
Ackermann effect
To adjust the progressivity of the steering angle of the wheel on the inside of the curve (Ackermann effect), the steering links can be reset to other steering
points both in the steering arms and in the steering plate.
Chassis
The „frame" of the vehicle, strictly speaking only the bottom support plate.
CVD drive shaft
A shaft which on one side engages the attachment on the differential with a steel pin and which on the other side is connected to the axle without tolerance via
a cardan joint for low wear. This way the wheel can turn even at a great steering angle (strongly angled shaft).
Damper plate
The upper end of the shock absorber of an axle right and left is screwed to the damper plate at the front or at the rear. The shock absorbers are thus somehow
interconnected via the damper plate.
Differential
Differential gear. Equalizes the different revolution speeds, e.g. between the wheel on the inside of a bend and the outside of a bend.
Butt screw
Regulates the minimum air supply to the carburettor in idle speed.
Receiver
Receives and „translates" the control signals of the remote control (direction and intensity) for the servo and the speed controller. The transmitter crystal which
is tuned to the receiver crystal ensures perfect communication between transmitter and receiver. Transmitter and receiver crystals are attuned to each other
in such a way that signals of transmitters operated parallel cannot influence this receiver (this model).
Throttle/brake servo
This servo controls the carburettor slide as well as the disk brakes
Transmission
Transmits the rotational speed of the engine in the drive section to the rotational speed of the driven wheels. The transmission ratio (rotational speed of engine/
wheel rotation) provides information about the final speed and the torque.
Main jet needle
Regulates the fuel supply to the carburettor
Steering servo
Servo engine that carries out mechanical control functions via a lever. This servo effects steering via the steering links.
Air filter
The air filter is made of foam. It prevents dust or dirt from entering the carburettor or the engine through the suction hole.
Oil pressure shock absorbers
The shock absorber consists of a coil spring with a piston in an oil-filled cylinder running up and down at the centre. The coil spring is supported by a plate on
the end of the piston rod and a knurled nut/distance ring on the outer side of the cylinder. The spring pre-tension can be adjusted by turning the knurled nut/
the distance rings of various thicknesses. The springs absorb the travel of the axel halves when driving on uneven ground. The spring retraction/protrusion is
inhibited by the piston running through the oil. By selecting different dampening oils the dampening properties can be varied. The shock absorber is mounted
between the damper plate at the top and the lower transverse link. The deflection travel is limited by a plastics sleeve.
Transverse link
Full-floating axle transverse to the direction of motion; connects the wheel suspension (spindle, axle leg and steering knuckle pin) with the chassis.
