How does a 2 speed RC transmission work?
To shift gears in this transmission, you move a clutch plate sideways so that it locks together with one or the other of the two gears on the output shaft. The gears can spin freely on the output shaft: they do not transmit any power directly.
How does a two speed gearbox work?
The transmission has two forward gears and one reverse gear, a neutral position, and the possibility of semi-automatic gear shifting. The neutral allows to safely tow the vehicle in the event of an electric motor failure, which was a specific requirement of the customer.
How fast can nitro go?
The fastest nitro RC car has a top speed of 100 mph, while the fastest electric RC car has a top speed of 200 mph. Nitro RC cars are heavier than electric RC cars because they have many parts attached to the top of the metal chassis.
What is a 2 speed clutch?
In a 2-Speed fan clutch, when the fan clutch is disengaged, the fan still rotates at 15-25% of the engine RPM. This fan rotation provides crucial airflow to the engine and draws virtually no horsepower.
How does a nitro RC clutch work?
When the engine is sitting at idle, the clutch shoes, which are held together with a clutch spring, contract around the crankshaft and do not touch the clutch bell. As the engine rotates faster the centrifugal force overcomes the spring and causes the clutch shoes to expand, which engages the clutch bell.
How does powerglide work?
Powerglides built prior to 1968 had a rear pump in addition to a front pump and could be push-started because the turning of the driveshaft creates enough hydraulic pressure to engage the clutches and spin the motor. This is another advantage for racing enthusiasts who use a Powerglide.
Why do electric cars have no transmission?
Electric cars don’t require multi-speed transmissions because of the so-called “engine” in an electric car, an electric motor. While internal combustion engines require multiple gears with different ratios for power output, electric motors produce a consistent amount of torque at any given RPM within a specific range.
Why do electric cars have a low top speed?
This is because most manufacturers of electric cars limit the top speed to preserve battery charge. Aerodynamic drag increases significantly as speed rises and hence battery power is consumed more rapidly when a high cruising speed is maintained. The other reason has to do with an electric car’s drivetrain.
