What is RC Car?

RC car (RC = remote control) is a miniaturized version of all kinds of real racing cars. It has the same mechanical principle as the real car, similar structure and handling characteristics, and the amazing speed that makes super sports cars feel inferior! Take one eighth of the level road remote-controlled cars, for example, which can accelerate from standstill to 100km / h in 1.6 seconds and reach a top speed of 160km / h. This performance is equal to that of the world’s most technologically advanced formula one racing cars, and makes all super sports cars blush. The reason why remote control model is considered as “hobby” rather than “toys” is that the remote control model requires players to have certain knowledge and technology, which is fundamentally different from toys that can be bought and played. Players can not only have fun in the operation of the model, but also constantly learn new knowledge in the model, exercise thinking ability and practical ability. Therefore, remote control model is definitely a hobby beneficial to the body and mind. Although driving a remote control model car can not control the steering wheel in the car, it can only control the car through the wireless remote control, but in fact, the pleasure obtained through the eyes is no less than that In the real car, because you can enjoy the lightning speed and strong ability to cross the corner. If speed is not your pursuit, you can choose a remote control vehicle with high fidelity or various interesting functions, such as watching several unreal container trucks walking, driving a jumbo to conquer rugged roads, and driving an AE86 drift remote control model car to deliver bean curd by Tuohai, who plays the first character D, is also a fun remote control enjoyment.

What is RC Car

Remote control model vehicles can be divided into two categories according to the power source. The first category is “EPRC car” driven by battery / electric motor, and the second is “GP RC car” with internal combustion engine as power output. According to the proportion, there are 1 / 28, 1 / 18, 1 / 10, 1 / 8 and 1 / 5. For example, 1 / 10 is about one tenth of the size of the real car. At present, there are 1 / 10 electric saloon cars, 1 / 10 oil powered saloon cars, 1 / 8 large foot trucks and 1 / 8 oil powered off-road vehicles. In the future, we will make an in-depth introduction to each type of vehicles. You can choose your favorite remote control model car according to the characteristics of each vehicle type, so that we can realize the model dream together.

The product of high technology

Remote control model car can be said to be a product of high technology, widely used in many advanced materials and technologies, such as carbon fiber, titanium alloy, aviation aluminum, in the remote control vehicle are very common parts materials. Moreover, the latest electrical / electronic technology and digital technology have been applied to remote control vehicles for the first time.

RC remote control vehicle frame

RC is the abbreviation of radio control. It is not a very popular sport either at home or abroad. Why do you say that? RC is really a sport that requires a lot of time and money. Therefore, those who have money foundation do not necessarily have the time, and those who have time do not necessarily have the money to play RC remote control model car entry – Adult remote control toys.

A complete set of RC includes the following parts (this article only takes the remote control vehicle as an example) firstly, the frame, the remote control system, the power and steering system, and finally some auxiliary materials such as tools and oil products.

The foundation of RC is the frame. Different types of RC models will have different types of frames. The figure above shows a flat road sports car, referred to as level running. Other categories include off-road vehicles, short-distance trucks, big foot trucks, climbing cars, F1, drift cars, etc. due to the different transmission structures, they can also be divided into belt drive and shaft drive. The above figure shows belt driven motor car. The frame can also be divided according to the proportion: 1:16 1:14 1:12 1:10 1:8, 1:5 and so on. Generally speaking, those below 1:20 are collectively referred to as mosquito vehicles, and the most popular ones are 1:10 and 1:8.

In fact, the biggest difference between RC and other remote-control toy cars is the frame. The RC frame can be adjusted from the height of the car to the inclination of the tire, the tightness of the transmission device, and the height of the shock absorbers. This is to adapt to different remote control methods and the needs of different venues. This is also one of the fun of RC. Even if the same frame is in the hands of different people, there will be different settings and different motion characteristics because of the manipulation.

RC Driver Cup/Shaft

Our factory specializes in RC Driver Cup/Shaft by CNC machining.

Drive shaft description

Working conditions

The driving shaft is subjected to, torsion, shear, tension, compression, impact and other alternating stresses, which can also cause the torsional and bending vibration of the drive shaft and generate additional stress; the stress distribution is uneven; there is sliding friction between the drive shaft journal and the bearing.

performance requirement

The main failure modes of drive shaft are fatigue fracture and serious wear of journal. Therefore, the material should have high strength, certain impact toughness, enough bending and torsion fatigue strength and stiffness, and the journal surface should have high hardness and wear resistance.

Drive shaft material

Forged steel drive shaft: high quality medium carbon steel and medium carbon alloy steel, such as 40, 45, 35Mn2, 40Cr, 45Cr, 35CrMo steel, etc;

Material selection

This kind of material is medium carbon alloy steel, which can be improved by quenching and tempering (or normalizing) heat treatment. In recent years, a new kind of steel, namely alloy quenched and tempered steel, has been widely used in high-power engines. The grain size is refined by adding alloy elements such as Si, Cu and Ti, strengthening the steel matrix and improving the strength of the steel.

CNC Machining for the heat sink parts

Radiator machining parts

Our factory is a professional CNC plus factory. The processed parts adapt to various industries. The accessories of the heat sink have been processed for more than ten years in our factory. The heat sink material is aluminum or copper. which is processed by CNC, drilled, tapped, deburred, cleaned, sandblasted, and then surface oxidized.

The principle of the heat sink is to increase the surface area and speed up the heat dissipation. As the material of heat sink is the metal with smaller specific heat, it absorbs heat very quickly, at the same time, the speed of heat loss is also relatively fast, so the effect of rapid heat dissipation is achieved through heat transfer.

For example, CPU of the computer use a heat sink,It can reduce the temperature of CPU and ensure the work of CPU.

For the material of heat sink, the thermal conductivity of each material is different, which is arranged from high to low: silver, copper, aluminum and steel.

However, if silver is used for heat sink, it will be cost too expensive, so the best solution is to use copper. Although aluminum is much cheaper, its thermal conductivity is not as good as copper.
