what type of transmission do stock race cars have

Unlike manual transmissions for a street car, NASCAR

stock cars use straight cut gears and no synchros. Straight cut and helical gears are the most commonly used in cars. The advantages of a straight cut gear while racing is that unlike a helical gear, they produce no axial load, which means there is no restriction on the amount of torque used.

It’s important that transmission and engine builders communicate expectations and work together to get the ultimate performance a customer is looking for. “We rely on information from each other, which is key to getting the right combination together for the customer,” Kelly says.

What is input shaft?

The input shaft is actually a two-piece unit consisting of an internal and external shaft – one driving the odd-numbered gears, one driving the even-numbered gears. Electronic control is the additional piece that makes them shift so quickly. When you’re in one gear, the computer preselects the next, so when you command it to shift, all that needs to happen is the disengagement of one clutch and engagement of the other.

What is NASCAR's transmission?

NASCAR is a popular racing competition in America that attracts tens of thousands of spectators to its events each year. Currently, NASCAR racing cars use 4-speed transmissions, which have not changed significantly since the time of a 1950's Ford. The reason of such a strange adherence to the classic designs (not only in transmission, but also in other components) in the time of fast-developing automobile technologies lies in strict technical regulations of NASCAR, which make this competition so special.

How does a NASCAR transmission work?

The NASCAR transmission (using the example of G-Force transmission) operates as follows: firstly, the power is transmitted to the input shaft of the transmission, which is not connected to the output shaft. Then the power goes to the countershaft via the drop gear, which is responsible for the overall change of gear ratios. After that, the power is transmitted to the gear which has to be engaged. When the 4-th gear gets engaged, the input and the output shafts get linked together and they rotate with the same speed, i.e. the 4-th gear in NASCAR transmissions is always 1:1 to get as much efficiency as possible. The reverse gear set in this transmission is positioned at the output shaft.

How does a NASCAR car get into gear?

To get into gear in the NASCAR car, the transmission mechanism uses a so-called dog clutch – durable claws on the side of 1 gear interact with slots in the side of the neighboring gear to drive the gear . The same principle is applied in motorcycle gearboxes. Simply reduce the load on the transmission and shift to the next gear.

How does NASCAR differ from Formula 1?

NASCAR differs from other well-known racing series – here driving skills and experience of racers and their teams play a greater role than talents of engineers who design and develop the cars. In contrast to Formula 1, where without sophisticated technologies you can forget about the victory, the NASCAR racing series can to some extent be considered as more just competition, where all racers are in equal conditions. Therefore, NASCAR officials still stick to strict rules that restrict implementation of new tech solutions on the cars and therefore placing utmost importance on the human factor.

Why is NASCAR so unpredictable?

This is why NASCAR races are so fascinating and unpredictable. In NASCAR, a tenth of a second can be a serious advantage over other racers. In F1 this same advantage would be about 1-1.5 seconds. Therefore, in an effort to keep its high audience appeal, NASCAR leaves small room for new technologies. The necessity to use the 4-speed manuals during these wild rides significantly increases the probability of the driver’s error, thereby stressing the importance of driving skills. Unlike the F1 paddle shifters that use a computer to do the shifting.

How many transmissions does a car have?

According to the regulations, each car can have 3 transmissions for every event, and the service life of each unit commonly reaches up to 4,500-5,000 miles.

Unless you’re able to spend a few thousand dollars on a transmission, you’re going to want a manual.

Why do we need a transmission?

A transmission’s second job is to give you more control over both engine and vehicle speed. Without a transmission, your engine has to work doubly or triply hard, both getting up to speed and then staying there. Your engine runs most efficiently when it’s operating around the middle of the RPM range. Horsepower and torque output are at their lowest at low RPM, and they start dropping off quickly at the higher end of the RPM range. The gearing in the transmission allows us to keep our engines working in the optimum RPM band.

Where are shift points on a trans?

However, unless you’ve got a manual automatic or have a modified trans, the shift points are probably going to be just below the beginning of the major part of the torque curve of your engine or just inside that “sweet spot” in the RPM/torque band.

Can you choose manual or automatic transmission?
