What is a Straight Spindle?

The straight spindle of a trailer refers to the axis that connects the trailer and the tractor, which is usually used for trailer driving in water or on low adhesion ground. The straight spindle of a trailer is usually made of high-strength steel, which has strong load-bearing capacity and bending resistance. It can adapt to different terrains and driving conditions by changing its angle and position. The straight spindle of a trailer is usually connected to the tractor's power output shaft through a transmission and transmission shaft.

What are the Differences Between Trailer Straight Spindle and Drop Spindle?

Trailer straight spindle and falling spindle are two different tractor spindle designs.The straight main shaft of a trailer is the main shaft that connects the tractor and trailer. It is usually an integral component made of high-strength steel and has strong load-bearing capacity and bending resistance. It can adapt to different terrains and driving conditions by changing its angle and position. The straight spindle of a trailer is usually connected to the power output shaft of the tractor, and is connected to the drive wheels of the trailer through a transmission and transmission shaft to drive the trailer.The falling spindle is a tractor spindle designed for driving in water or on low adhesion ground. It usually consists of multiple parts, including the spindle, bearings, gears, etc. The falling spindle can adapt to different terrains and driving conditions by changing its angle and position. It usually transmits the power output of the tractor to the trailer through a special mechanism for driving in water or on low adhesion ground.Overall, both the trailer straight spindle and the falling spindle are designed for tractor spindles, but their purposes and design methods differ.
