Description

Technical Field

[0001] This utility model discloses a transmission device, belonging to the field of management vehicle technology, specifically relating to a large integrated management vehicle transmission device. Background Technology

[0002] Mining transport vehicles play multiple important roles in mining operations, primarily including improving transportation efficiency, ensuring personnel safety, reducing production costs, and adapting to complex underground mining environments. Mining transport vehicles significantly improve transportation efficiency. These vehicles typically have a large load capacity, enabling them to transport large quantities of ore, coal, or other mineral raw materials at once. Compared to manual handling or small transport vehicles, this greatly reduces the number of transport trips, saves time, and accelerates the overall mining operation. Furthermore, mining transport vehicles possess good power performance, allowing them to maintain high speeds under complex underground road conditions, thus increasing the turnover rate of minerals.

[0003] Small mining pipe transport vehicles with transmissions use electric motors to drive the wheels. This type of transmission is inefficient and has poor safety. In some large mines, there is no gear shifting device, which makes it impossible to accurately control the speed of the entire pipe transport vehicle and requires high operational skills from the staff.
