For a number of reasons, Russia's road transport is becoming increasingly important. Cars are widely used in all areas of the national economy, perform a significant amount of transport work, or rather serve to transport goods and passengers.

The most important requirements for the designed machine include cost-effectiveness in manufacture and operation, reliability, rigidity and vibration resistance, and workability of the design. To meet these requirements, all structures are supported by calculations, the most important of which are strength and stiffness calculations.

Conclusions and conclusions

In the presented course design, a truck transmission was designed with a detailed development of the design of a three-speed gearbox. Traction dynamic properties of the car were also determined.
