The safety problem of hand-held tractor steering

Hand-held tractor with claw-type steering mechanism, when the steering handle is used to operate the jaw clutch, the power of one side driving wheel is cut off. When the turning radius is small and the steering speed is high, sometimes a serious accident is caused by the late turning of the steering handle. . So, how can we use it to ensure that the locomotive turns safely?

1. When starting, try not to turn to start the turn. The drive wheel on the power-cut side stops and the drive wheel on the other side that does not cut off the power steadily turns around the stationary drive wheel. It is not easy to control. The good engagement of the claw-mounted steering gear is ensured by the steering spring. If the spring force is weak or the steering handle is moved by others, the gear teeth of the steering gear will easily be caught by the teeth of the central reduction gear hub when the vehicle is parked, so that the side driving force will be cut off. In this case, the tractor will suddenly start to steer. An unexpected accident occurred.

2. When using the steering handle to steer uphill when climbing uphill, if the steered steering handle is used, the driven wheel on the side where the power is cut off will quickly change from advancement to standstill under the action of the downhill force, while the power is not cut off on the side of the drive. The wheel is still running, the turning speed is high, and it is easy to make the tractor run out and cause an accident.

3. As far as possible when driving downhill, steering will not be applied when the handle is turned downhill. In the case of a steep slope, the side that cuts off the power (equivalent to neutral) is faster than the side that does not cut off the power. When the steering is reversed, the handle is reversed, that is, the right steering handle is rotated to the left. When the slope is not large, it is also the reverse that the reverse is not easy to grasp, but also easy to accident.

4. It is forbidden to use the steering handle when driving at high speeds. Steering handles are used during high speed driving. The tractor turns sharply, which may easily cause a rollover accident. The correct course of action is to decelerate the big bend, observe the condition of the road and pedestrians, and then steer the steering handle. If the camber is not large, there is no need to operate the steering handle, and the handrail can be smoothly steered by pushing the handstand.

5, when reducing the throttle to avoid steering suddenly reduce the throttle, the engine's power becomes resistance, locomotive inertia becomes power, then steering steering handle, is likely to reverse. Since this situation is not easy to judge, steering should be avoided as far as possible.

6. In any case, it is not allowed to use two steering handles at the same time to do a little carelessness. It is easy to loosen one side steering handle to cause a high-speed sharp rotation or to release the double steering handle to cause a slope. If you are in a downtown area, it is easy to hurt people and cause a car accident. When going uphill or downhill, it will cause uphill backsliding and downhill acceleration. It is also extremely unsafe.
