Is the wheelbarrow gimbal in the front or in the back?

As a common tool in human life, wheelbarrows provide us with convenience and efficiency. In reality, we will find that the wheels of the cart are composed of two sets of directional and universal wheels, so how should these two be distributed?

Generally speaking, it is more reasonable to arrange the flatbed trolley with directional wheels at the front and universal wheels at the rear. The rear universal wheel mainly controls the direction and requires less torque when changing direction. Therefore, it saves energy when turning. The front is directional wheel, when walking in a straight line, the arm control to adjust the direction requires less force. When turning, it is more flexible. In general, the universal wheel and directional wheel with the use of the general cart is the front two directional wheels, the back two universal wheel, when the trolley needs to turn, the back of the universal wheel with the thrust, will push the front of the two qualitative wheels to turn together, so as to complete the trolley steering problem.

Unless there are special requirements for the use of the environment. For baby strollers, you will find that the universal wheels are all on the front, this is because, this kind of stroller is generally forward force, rarely pull backward. Baby strollers have to play a role in facilitating steering, so they are mounted on the front. But mounted on the front, but also often because of the reason of the thrust, the front of the universal wheel steering is not good operation. The good thing is that the stroller is small and easy to control.
