Tractor Head Truck

HOWO tractor truck is Sinotruk inheriting the excellent characteristics of HOWO brand to adapt to the working conditions and cost-effective needs of China and developing countries. Parts to make its reliability, economy, and technical indicators reach the highest level, and the tractor truck matching design focuses on the reliability, economy, safety, and environmental adaptability indicators of products. 

The cylinder block of this tractor truck is made of vermicular graphite iron, the gantry frame, the skirt part is designed with spherical shape, and the connecting rod and crankshaft adopt the expansion and breaking process, which is guaranteed. Modular design, reducing the number of parts by 25%, lower weight, and fewer failure points;

Details of the tractor truck

The front axle of the HOWO tractor truck has the functions of light weight and heat dissipation, which is more advantageous than the current models of the same level in terms of comprehensive cost performance. 

A lightweight parabolic steel plate suspension is used. This configuration has a more lightweight effect and reliable load-carrying capacity in the existing environment. In addition, the stabilizer bar and vertical hydraulic shock absorber are safer in bumpy road conditions.

The double parallel axle of howo tractor adopts V-shaped thrust rod, which has excellent stability and reduces the occurrence of dangerous situations such as rear axle displacement caused by the vehicle running on non-paved roads.

It can be clearly seen through the chassis that a very detailed bundled piping arrangement is adopted, which is convenient for timely search and maintenance when the vehicle has circuit faults in the later period.

Feature

Brake system

The braking system of the howo tractor is basically the same as that of the truck. The difference is that the tractor is provided with the pneumatic brake pipeline, emergency brake pipeline, starting brake pipeline and Pipe fittings, etc.

In addition, a hand brake valve is set in the crossbow cab, which can directly control the trailer brake. In order to improve the braking performance, the howo tractor is equipped with a load sensor at the rear axle to improve the reasonable distribution of the braking force between the axles.

Suspension

In order to improve performance and adapt to heavy load requirements, howo tractor adopts independent suspension or thicker leaf springs than ordinary trucks. For tractors with dual rear axles, almost all of the rear suspensions currently use half-elm leaf spring balance suspension.
