Ackermann angle refers to the angle formed between the two steering wheels when the vehicle is turning. The following is a detailed introduction about Ackermann angle: 1. Overview: Ackermann angle refers to the angle formed between the two steering wheels when the vehicle is turning. Ackermann refers to the geometric characteristics of the steering system shape, which causes the inner wheel to turn more than the outer wheel when the vehicle is turning. The inner wheel usually turns at a larger angle than the outer wheel. When the steering angle is increased, this angle will also increase accordingly. 2. General situation: Usually, the Ackermann angle is set by changing the fixed hole position of the steering push rod on the steering cup. When the angle of the steering push rod is larger, it will produce more Ackermann angle, and vice versa. Since the turning radius of the inner and outer wheels is different when the vehicle turns, Ackermann can help the two front wheels point in the correct driving direction respectively to obtain more grip.

Can the air conditioner filter be installed when it's not dry?

Can the air conditioner filter be installed when it's not dry? As long as there is no large amount of water attached to the surface that could flow down the panel, it can be installed. After cleaning, shake off the water on it and then put it back in. Do not expose it to sunlight or dry it over an open flame (such as a stove) to avoid deformation of the filter. If the air conditioner filter is installed while still wet, turning on the air conditioner will soon dry it out automatically. The air conditioner filter has a concave-convex honeycomb structure and can be widely used in air filtration and sewage filtration systems. During the spinning stage, antibacterial agents (DEP) and mildew inhibitors (TBZ) are directly mixed into the PP resin raw material, giving the produced filter antibacterial and anti-mold properties.
