It is a beautiful dream for tourists to take part in one of the most exciting and exciting motor sports. And driving karts, children’s racing, luxury racing games is an important way to realize this dream.
F1 (Formula One) is the goal of professional racing, and Karting (KARTING) is the cradle of F1 sports. The structure of the karting is very simple. Generally, a continuously variable engine and a 1:1 steering wheel are used. The left foot is the brake and the right foot is the accelerator pedal. It only moves forward without reversing, so it is very convenient to operate. If you have the courage, anyone can do it.
Karts are characterized by safety, high speed, and no danger, and because the body design is only 3 to 4 cm above the ground, it is almost impossible to overturn. At the same time, since the driver’s line of sight is only 70cm from the ground, and the body is completely exposed, the somatosensory speed must be 3 or 4 times higher than the actual speed. In addition, the straight-line distance of the kart track is very short, and there are many small curves. The sense of speed is becoming more and more obvious. People sit in the car as if they are about to fly, rush straight forward, make a sudden turn, and the rear of the car almost slides sideways, feeling as if they are about to be thrown, which is exciting. and challenging.
There is no need to worry about safety when driving a karting, because even if it hits the safety fence (or hits the buffers on both sides of the track), it will not be dangerous, and it will only be a spin at most, and the karting also provides drivers with helmets and seat belt. There are two types of karts: continuously variable speed change and belt gear.
Japanese Yamaha company also specially designed a kart for children, which can be driven by 7-year-old children. Karts are divided into two types: popular type and competition type. The popular type is also called leisure type. The speed of this kind of car is not very fast; the speed of the competition type kart is very fast, and its chassis is extremely low.
There are two kinds of racing cars for children and luxury racing cars for adults. The characteristics of children’s racing cars are slower, generally below 25km/h. Now there are low-speed karts specially suitable for children aged 6 to 9, and their speed is also controlled below 25km/h. Children’s racing cars are generally driven by battery-powered electric motors, which are easier to operate than go-karts and have smaller car bodies; racing tracks are generally 4 to 6 m wide, with many straights and fewer sharp turns.
Luxury racing is not as intense and exciting as karting, and it is not as thrilling as F1 racing. It is completely an adult car game to experience leisure and entertainment. The beautiful racing track is almost similar to that of karting. Luxury racing cars have beautiful and luxurious sedan bodies. Whether it is a closed sedan or an open-top luxury racing car, the driver is not completely naked. Therefore, it can bring tourists a sense of psychological security.
There are various styles of luxury racing cars, with comfortable seats, beautiful and peculiar shapes, and there are two types of single cars and double cars. However, like all luxury race cars and karts, there is a solid ring of crash panels around the body. The anti-collision enclosure can be made of elastic steel plate or rubber material. Its function is to absorb the energy of the collision between vehicles or the collision between the vehicle and the guardrail next to the racing track, so as to protect the vehicles and tourists from injury.
Luxury racing cars and karts sometimes appear on the karting arena at the same time to meet the driving interests of different tourists.
1.The main structure of karts and racing cars
Karting and racing rides consist of two parts: the body and the lane.
(1) The main structure of the go-kart. The body of a kart consists of a vehicle, a lane, and the like. The vehicle consists of seats, wheels, accelerators, brakes, handles, engines, safety devices, etc.
The shape and main parts of the kart
(2) The main structure of the car body The car body of the car is composed of the cockpit, steering mechanism, driving mechanism, anti-collision device, walking device, accelerator pedal, brake and safety protection device.
1) Cockpit. the cockpit is made of FRP, and the cockpit is not allowed to have defects such as poor impregnation, poor curing, air bubbles, delamination of cutting sections, and uneven thickness; cracks, damage, obvious repair marks, and cloth patterns are not allowed on the surface. Exposed, uneven and uneven defects, the transition at the corners should be rounded; the inner surface should be clean.
2) Operating system and engine. The racing operation part consists of steering wheel, accelerator pedal, brake and steering mechanism, etc.The steering mechanism consists of a linkage mechanism.
3) Buffer device. the buffer device consists of anti-collision steel plates and rubber buffer blocks. The anti-collision steel plate is made of alloy steel material, which is crash-resistant and safe; the rubber buffer block is placed at the bottom of the car to protect the chassis. In addition, the rear of the car is also equipped with a brake handbrake device.
2.Lanes and pavements
(1) Lane. The lanes of karts and racing cars should be flat and solid, and there should be no unevenness; for roads that allow overspeeding, the width of the road surface should not be less than 5m, the slope of the road surface should not be greater than 5%, and the turning radius (inner diameter) of the road should not be less than 5m; On the road, the width of the road should not be less than 3m, the slope of the road should not be more than 5%, and the turning radius (inner diameter) of the road should not be less than 5m; there should be no obstacles in the road, and no branch lines should be inserted.
(2) Pavement. There are two kinds of road pavement: cement pavement and asphalt pavement. Concrete driveways are tough and durable. The color of the road will affect the temperature of the driveway, especially in the hot summer, the cement road is much cooler than the black asphalt road, so that employees and tourists will feel more comfortable, and the damage to the tires is also greatly reduced.
Cement pavement driveways can be used for many years if the construction quality is good. Because the karts are small, they lack elastic damping, and cannot jump, which means they are easily damaged on uneven roads, and the smoother the road, the longer the life of the karts and the more fun for tourists. It is also important to accurately place the vertical and horizontal shrinkage devices and the width of the gap in the cement pavement.
Improper gap of the gap or poor pavement quality can cause the driveway to suddenly collapse and damage the vehicle. The depth of voids and joints is determined by the thickness of the slab and the use of reinforcing steel and the shape of the driveway. The characteristics of asphalt pavement are suitable for building highways and parking lots, but the effect of building kart lanes is not as good as cement pavement.
Because when the weather is hot, the asphalt will move, creating ruts, which can easily lead to loss of control. After the rain, it will take longer to restore the road surface for reuse. The advantage of asphalt pavement is that it is not easy to oxidize,The cost is low and the construction is easy; the disadvantage is that the cost of pavement repair and vehicle maintenance is higher than that of cement pavement. The width of the go-kart pavement for tourists to play should be no more than 8m, and sufficient safety zones should be reserved on both sides of the road.
(3) Parking guards. The purpose of setting up parking lot guards is to define the boundaries of the lanes to protect the safety of people and vehicles. Because when the vehicle cannot guarantee the correct driving direction and hits the protective device, it can absorb or disperse the energy of the collision, which can avoid or reduce the damage to the human and vehicle body. That is to say, the yard protection device has the following three functions: one is to keep the vehicle in the lane; the other is to protect the driver, employees and bystanders; the third is to reduce the damage to people and equipment caused by the collision. According to these requirements, appropriate protective measures should be selected with emphasis.
(2) Safety devices The safety devices of karts are mainly front and rear brake devices and seat belts. To ensure safety, the following points should also be noted:
1) Acceleration and braking devices must be clearly marked.
2) The braking device must be safe and reliable, and the maximum braking distance should be less than 7m.
3) The gasoline engine fuel tank should be well sealed and there should be no leakage.
4) A rear braking device should be installed, and the pawl and the tooth surface of the ratchet should be in close contact and rotate flexibly.
5) Back cover protection should be set.
