Recently, a certain type of aircraft tractor produced by Qingdao Special Purpose Vehicle Company of China National Heavy Duty Truck Group was sold to a country in South Asia for the first time. The service personnel of the special automobile department of the Chongqing-Tsinghua University went to deliver the vehicle and conduct on-site training for the users.
It is understood that Sinopec Qingzhuang is the first company to develop aircraft tractors in China, with a history of more than 20 years of research and development and production of aircraft tractors. With deep technical know-how, CNHTC successfully developed a variety of military and civil aviation aircraft tractors and continuously achieved technological breakthroughs. Compared with imported products, its research and development aircraft tractors are cost-effective and have a low cost of use and maintenance. And many other advantages.
Among them, civil aviation aircraft tractors have the following technical features:
Hydraulic mechanical transmission: Hydraulic transmission has the advantage of infinitely variable speed. Combined with a mechanical gearbox, the vehicle speed can be changed from 0-30km/h without any gear change. When hauling an aircraft, the speed is from 0-9km/h without shifting. There is no power interruption in the traction process and there will be no impact on the aircraft.
The micro-motion of the hydraulic transmission is good, and the lowest stable speed can be lower than 0.1km/h. It is close to the aircraft when the tow bar is docked and has good maneuverability and high safety. The hydraulic transmission also has the ability of dynamic braking. As soon as the throttle is released, the vehicle can be gradually decelerated, reducing the impact on the aircraft and the wear of the braking system.
Full-time four-wheel drive: The front and rear axles of the vehicle are respectively driven by a single motor in parallel, which is a four-wheel drive at any moment to meet the relevant requirements of the national military standard. By properly matching the axle load, the vehicle weight can be converted into driving force in most cases.
Versatility: The versatility of the car is manifested in many ways. The traction force of the vehicle is large, and the height of the traction bolt is adjustable.
Four-wheel Independent Steering: A computer-controlled four-wheel independent steering system with four steering modes for easy use on all occasions ensures that the four wheels do pure rolling in any steering mode and any corner to prevent tire wear.
