A tool for turning a car on the spot, and what car can be turned on the spot

Technical briefing: This device is used to turn or turn the car into the desired position when it is not easy to turn and turn around due to the narrow road. And can be used instead of jacks.

It is composed of supporting plate, support shaft, oil cylinder, oil pump support, track, worm gear and worm, gear fastening insurance, etc. The transmission part adopts gear reversing, and the self-locking characteristics of the worm gear and worm are used, so that the wheels will not rotate by themselves due to uneven ground when they leave the ground. The lifting device adopts a combination of hydraulic pressure and fork support.

It is not easy to shake when the body is slightly heavy. After the track is lifted, it is automatically locked with a screw to fasten the safety to prevent the track from falling. This device is suitable for cars and various models installed in front-wheel drive cars and various models installed below tons.

When the chassis is manufactured, a raised installation position can be made at the center of gravity between the first two seats, and the transmission device is connected with a toothed clutch on the first axle of the transmission. It is used for the power of lifting and turning the car body. When using, you don't need to get out of the car, hang the transmission into neutral, press the switch, connect with the power, pull the reversing valve handle, and the divider screw will automatically disconnect the track to jack the car down and release the reversing valve.

Pull the steering handle to turn the direction of the car (up to 180 degrees to the left and right hands and 90 degrees to the right) to the desired position, and then pull the valve handle to retract the bracket screw and tighten the safety automatic pin, and drive the car to the desired position.

I don't think about this thing, so I turned around on the spot.

The cars that made a U-turn were BYD's U8 and U9 cars.

On January 5, 2023, the "Dare to Cross the Galaxy" Yangwang Brand and Technology Conference was held in Shenzhen, officially releasing the new high-end automobile brand Yangwang and its core technology "Yi Sifang". The new energy hard-core off-road U8 and the pure electric performance supercar U9 were also unveiled simultaneously, with functions such as in-situ U-turn, emergency floating, and high-speed puncture control.

U-turn on the spot is commonly known as "tank U-turn", and there is no steering wheel of a traditional car on the tank, and the direction of travel of the tank is controlled by the speed difference of the tracks on both sides. The "tank U-turn" is to turn the tires on both sides at the same speed and in opposite directions, so that the vehicle can be circled in the center of the vehicle and turn on the spot.

One of the highlights of looking up to the U8 is that it can be done on high-adhesion roads such as asphalt roads, which requires higher power output and control fineness of the vehicle.

Four-motor independent control platform "Yi Sifang".

The core of "Yi Sifang" is a power system with four-motor independent drive as the core, including front and rear dual motors, ** controller and blade battery, which can be applied to pure electric and hybrid platforms.

The four motors can be controlled independently, and with the comprehensive reconstruction of the characteristics of new energy vehicles from the three dimensions of perception, decision-making and execution, the vehicle four-wheel wheel end dynamics can be independently adjusted at millisecond speed through the more perceptive electric drive system, so as to better control the body attitude.

By separately controlling the power output and rotation direction of the four wheels, the "Yi Sifang" platform model can realize in-situ U-turn, lateral movement, puncture tire and continue driving, Zheng dismantling lead and floating mode.

Find a wide and flat ground and choose a vehicle with a lower chassis and better stability. Pressure the car 4 tires to the lowest value of the standard air pressure (in order to increase the smoothness of the vehicle).

First of all, the vehicle accelerates to a certain speed (usually 80-90 per hour), then puts the left hand on the steering wheel at 10 o'clock, holds the hand brake lever with the right hand, and holds the release button. At this time, I stepped on the clutch, and suddenly the steering wheel was quickly hit to the direction of 12 o'clock, and the car body shook to the left because of the reaction force, and the water and electricity bills were discharged.

At this time, the next step is immediately carried out, the steering wheel is quickly hit to the direction of 6 o'clock, and the car body shakes to the right because of the reaction force, and then pull the handbrake hard! Because the rear wheel of the vehicle is locked, the rear of the car is thrown outward, and then the hand brake is continuously tightened, and when it turns quickly to 180 degrees, it returns to the steering wheel, and after the vehicle stops, put down the hand brake and hang a gear to leave. The saying is to send a third party to the other party.

Make a 180-degree U-turn with your left hand on the steering wheel and your right hand on the handbrake. Use 2nd gear to increase the speed to 50 km/h, for example, turn to the left, first slam the steering wheel to the right, about half a lever to 1 4, and then jerk the steering wheel to the left, still about half a lever, while pulling the handbrake. The tail of the car will drift by inertia.

The amplitude of the direction is related to the speed of the car, and the faster the speed, the smaller the amplitude of the steering wheel. It is up to the learner to experience it. The 180-degree U-turn to the right is the opposite.

Stepping on the accelerator, the direction is killed, and it drifts when the handbrake is pulled.

The question is simple. If the library will be moved, it will turn around in place. It is difficult to grasp it by asking others, the key is to ponder and experience it yourself.

The direction kills slamming on the accelerator and it is necessary to pull the handbrake.

1) Select the location.

If a car makes a U-turn, it must strictly comply with the provisions of the Road Traffic Management Regulations": "Motor vehicles are easily allowed to make a U-turn at railway crossings, pedestrian crossings, detours, narrow roads, bridges, steep slopes, ramps or dangerous roads." "Therefore, we must choose a small traffic junction, flat, wide, solid lot, depending on the width of the road and the traffic conditions, the vehicle can be divided into U-turns, U-turns along the parking lot, or a combination of U-turns.

If these conditions are not available, there is also the option to use the space and make a U-turn of the vehicle.

2) Basic operation of U-turn.

Make a one-time U-turn. In the case of a wide road, a U-turn should be applied in the case of a large one. This method is fast, convenient, economical and safe.

If there is an appropriate traffic control officer, a U-turn signal is given beforehand, and the command officer obtains permission and indicates that the traffic is in low gear and honking the traffic slowly to make a U-turn at a lower speed.

A combination of ride-forward and reversing. If the road is narrow and you can't turn around, you can use a combined U-turn method to go forward or backward.

U-turn, first choose the appropriate position, turn left signal, the car slowly to the side of the road, turn the steering wheel, the wheel is approaching the side of the road or near the vehicle near the obstacle at this time under the clutch lightly press the brake pedal, the vehicle has not completely stopped, the steering wheel, the right foot quickly, go back to the front wheel needs a new direction, and immediately stop the car. Return, you should clearly observe the situation of reversing, and then slowly start turning to the right foot steering wheel until the rear wheel of the car will approach an obstacle near the side of the road or the trailing edge of the car, immediately press the clutch pedal, lightly step the parking brake pedal, and use this opportunity to quickly turn the left side of the steering wheel before stopping. The front wheels need a new direction to move forward.

At this point, if we continue to open, but forward or backward again, we can repeat the U-turn several times.

When making a U-turn, in the case of special circumstances (highway slope or reduction), regardless of forward, backward, or stop, in addition to using the foot brake, the hand brake must be used until the vehicle is completely stopped, and then the gear is moved forward or backward. In operation, it should be a steady hand grip on the steering wheel, on the one hand grip the hand brake lever, the foot clutch pedal slowly and relaxed, while the foot accelerator pedal action is appropriate fuel, combined with most clutches, hand brake when relaxing pole, the car gradually and steadily forward or backward.

In the process of making a U-turn, make enough entry to be positive, since the distance of the wheels approaching the curb is not equal, in determining the parking space, the obstacle on the road should be closed on either side of the wheel, if there are any restrictions, moving forward, should be subject to the bumper, when coming back, the rear car can go to the plate or rear bumper, do not touch the obstacle.

When making a U-turn in a dangerous area, the rear of the vehicle should be facing the safety direction and the front of the vehicle should be facing the direction of the risk. It's better to make more U-turns than to take the risk of doing it in one step.

Hit the steering wheel to turn around.
