5. Terminology
2WD, 4WD
2-wheel drive or 4-wheel drive
Steering knuckle (C-stroke)
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.
Chassis
The "frame" of the vehicle; actually 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 from 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).
Fail-safe
Electronic circuit that moves the connected servo into a freely selectable position in case of an interruption of the radio contact e.g. if the range is exceeded
or in case of a transmission error. Once radio contact is restored, the servo reacts normally again to the control signals. The fail-safe function can be integrated
in the receiver and can as well be inserted between the receiver and the servo as an additional constructional element
Throttle/brake servo
This servo controls the slide carburettor as well as the disk brakes
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. A servo saver integrated in the servo
control lever protects the servo from damage that can be caused by hard shocks transmitted through the wheels via the steering links to the servo transmission.
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. The air filter must always be treated
with air filter oil.
Casting
Angle of the pivot pin in driving direction. Caster means that the point of intersection of an imaginary line lies parallel to the pivot pin with the base in front of
the point of contact of the wheels.
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 preload 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.
