With the rapid development of heavy truck product technology at home and abroad, truck users have higher and higher requirements for trucks. In order to implement the concept of maximizing user value, Sinotruk has cooperated with international first-class suppliers to design and develop important parts according to the international assembly design standards, and has walked out of a new road of international technical cooperation. It took three years to create a beautiful, practical, and new overall layout Howo a7 Tractor Truck.

Howo-a7-Tractor-Truck

  • Howo a7 Tractor Truck, which follows the development direction of international heavy truck, has successfully broken through the domestic heavy truck technology system and built a new platform for domestic high-end heavy truck, and is known as the “heavy truck leader and the king of highway” in China in the industry. The new front axle with light weight and strong bearing capacity, safe and comfortable front disc and back drum, is called high-end heavy truck with its strong power system and optimized transmission system.

Cab

Howo a7 Tractor Truck is divided into HOWO-A7 4 * 2 traction truck and HOWO-A7 6 * 4 traction truck. Both drivers are divided into A7-P (single bed) and A7-G (double bed), both of which have fashionable and beautiful appearance, spacious space and comfortable environment.

Engine

The Howo a7 Tractor Truck has a newly designed Sinotruk D12 series engine, which is known as the most fuel-efficient engine in China, with a power range of 340-460 Ps. With large displacement and high power starting from low idle speed, its wide speed range enables the whole machine to obtain constant power value and greater torque value, which determines the perfect fuel economy and driving performance of the D12 engine.

Axle

The Howo a7 Tractor Truck has a 9-ton front axle with standard disc brakes, which is the latest front axle developed by Sinotruk. It is better than similar domestic vehicles with low weight, high reliability, high stability and handling spirit.

Gearbox

The gearbox of the Howo a7 Tractor Truck is an electric, automatic transmission at 16 gears, just like a highly skilled driver with higher fuel utilization in a truck. The working principle and structure of AMT are completely different from the AT of a sedan. AT for cars is the mode of driving hydraulic oil by turbine and hydraulic oil again driving mechanical device. The efficiency loss of oil drive is large, so 100 kilometers generally consumes 1-2 liters more fuel than the manual box.
