The 16th Winter Olympics 100 Questions | What are the similarities and differences between the steel-framed snowmobile and the snowmobile?
Just as the same name is similar, as the two competitions in the Winter Olympics, there are many similarities between the steel framed snowmobile and the snowmobile.
First of all, steel-framed snowmobiles and snowmobiles are winter projects with a long history.
The snowmobile originated in Switzerland and has been listed as a competition event since the first Winter Olympics; the birth of the steel frame snowmobile can be traced back to the end of the 19th century, with a history of more than 120 years.
Secondly, speed is the most important aspect of the two sports, which is also the basis for judging the outcome.
The steel-framed snowmobile, known as the "Ice Dive Machine", was "exited" twice from the Winter Olympics because it was too thrilling, and it was not stabilized until after 2002.
The snowmobile is "F1 on ice", with an average speed of about 100 kilometers per hour and a maximum of 160 kilometers per hour.
In addition, the steel-framed snowmobile and the snowmobile race use the same track, and even share the same starting point.
The entire track is 1200 to 1650 meters long, with a drop of 100 to 150 meters.

Although there are many similarities, there are still differences between the steel-framed snowmobile and the snowmobile as the two events.
The first is the car body. From the appearance, the snowmobile is more like a traditional car, with players sitting in it to compete.
The steel-framed snowmobile is more like a "board" in which the athletes slide with their heads facing forward in the competition.
Another obvious difference is that the steel-framed snowmobile has no steering gear and braking device.
The bottom of the steel framed snowmobile is composed of a frame weighted by a lead block and two fixed tubular steel blades. The front and rear of the car body are equipped with buffers and a handle is installed in the middle. They are used by athletes to push the snowmobile when starting, and it is also helpful for athletes to stabilize their bodies. Inside the car.
To prevent injuries, athletes need to wear a series of professional equipment including helmets.
The rules also have requirements for the body and the weight of the athletes. If you are overweight, you need to lose weight.

The rear of the snowmobile is equipped with a brake, and the helmsman drives the snowmobile through a pulley system controlled by two handles in the snowmobile.
The rules also have requirements for the body weight of the snowmobile body and the athlete's weight. If the weight is not enough, the body weight can be used as a counterweight.
In the upcoming Beijing Winter Olympics, both of these competitions will be held at the National Snow Sled Center in the Yanqing Division.
Among them, the steel framed snowmobile produced 2 gold medals, and the snowmobile contained 4 gold medals, namely men's four, double and women's singles, and doubles. Women's singles were newly added for this Winter Olympics.
