Drives
General
There are many different ways to build a drive in a model car.
In the area of remote control (truck trail) multistage drives are often used. However, they did not work well in the car-system area.
There are different uses. This results in different burdens.
- Remote control vehicles are driven a little and there are shunting maneuvers, forward and reverse
- Car systems are usually driven only in advance, but long travel times
The easiest way is the technique used by Faller®
A steel screw and brass gear can withstand continuous operation for 8 hours a day for about 6 months.
Provided a good regular maintenance.
For example, we have vehicles at the exhibitions / stock exchanges that are already over 4 years old.
(duration 12 hours per week)
The same findings were made here. forum entry
For DC-Car the partner company GL-Classic has developed a high quality transmission.
We have lost less than 1% of outages in 3 years and 700 built drives.
But these were not pure wear failures but defective due to incorrect handling:
1. The gear must not be oiled, as this may swell the plastic, causing the gearbox to jam.
2. If the gearbox is mounted in a brass frame, it may no longer be soldered to it to avoid thermal damage.
comparison after 5 weeks
As always with high-priced products, the competition tries to make it cheaper.
The result can be seen here in comparison:
The cheap drive is worn after 5 weeks of practical continuous use (8 hours daily).
The worm and gear are used up. Whether the ball bearings continue is questionable.
'Try a replica'
The construction with ball bearings would suggest a better quality
In practice, it does not help if other components fail.
Here to see wear on snail and gearwheel
The test vehicle was serviced every 14 days as well as the other vehicle.
In order to have no impact from the outside, the vehicle was used on its own route.
After the gear had run out, we got from the manufacturer a "reinforced" gear.
After a short time, the snail was eaten.
By contrast, the original GL drives have been in constant use since 2010.
'GL1-46-7'
The drive is here at a
Semitrailer installed in trailer.
Maintenance:
The plastic parts must never be oiled!
This can soften the plastic material.
Previously, we thought the bushings should be treated with non-resinous oil.
That's what we're going to do. The oils give rise to green rot at the engine and at the bearing bushes.
This jams the drive. The smaller drives GL1-26-7 will no longer have Buchsne installed.
Has proven itself by Contact Chemistry The Spray Contact 61
After thoroughly wringing with the tweezers, you can eliminate noise with the spray.
The power consumption goes back extra, the travel time is extended.
'An unwanted stress test'
(about 1 hour before an obstacle driven)
Tire 1.5 mm smaller.
Gear and snail need only a cleaning.
There is no signs of wear despite overload.
(In the long term, the engine will not do that)
GL26 or GL46 1 rechargeable battery or 2 rechargeable battery
Small gear - Small 8 mm wheels 1 or 2 batteries depending on the desired speed
Large gear - Large 12 mm wheels 1 or 2 batteries depending on the desired speed
Small gear - average 10mm wheels mostly 1 battery depending on the desired speed
Small gear - big 12mm wheels actually always 1 battery depending on the desired speed
If 2Akkus are too fast, a diode reduces ½ "battery" (0.7V).
With 2 diodes, a whole "battery" (1.4V) is reduced.
The difference to a battery, the decoder runs with 2.4 V and the motor with 1.2 volts.
This saves electricity and extends the journey time. Therefore, 2 batteries, if possible, are beneficial.
higher quality drives
Some vehicles in the DC Car Team are equipped with even more complex drives.
These are equipped with higher quality Faulhaber engines and attachment gears
For example, they exceed the 200,00 Euro in production.
This is something for more exclusive models.
Therefore, the GL drives represent a good middle ground between cheap drives and high-tech drives.
