Abstract

The article provides an overview and analysis of the current state of development of 6x6 ATVs and the scope of the developed ATV, as well as technical characteristics of 6x6 ATVs with a mechanical transmission. The choice and justification of design solutions for a 6x6 ATV with an electromechanical transmission are presented. Also, the selected structural and design solutions for the developed ATV are substantiated based on the selected electric drive scheme taking into account the traction calculation for the selected electric motor.

Highlights

  • The developed ATV with an electromechanical transmission and a 6x6 wheel arrangement is designed to transport people and small-sized cargo in off-road conditions except for virgin snow with a snow depth of more than 250 mm and is characterized by the ability to overcome natural and artificial obstacles such as slopes, slopes, trenches [1]

  • The requirements for the characteristics of the developed ATV were formulated based on an analysis of the technical level of 6x6 ATVs on the market since ATVs with a 6x6 wheel arrangement and an electromechanical transmission the design of which is the work of [5] are absent on the market; 6x6 ATVs with a mechanical transmission were chosen as analogues

  • For this 6x6 ATV under development with an electromechanical transmission there are many design solutions determined by the selected electric drive scheme

Summary

Purpose of the developed ATV

The developed ATV with an electromechanical transmission and a 6x6 wheel arrangement is designed to transport people and small-sized cargo in off-road conditions except for virgin snow with a snow depth of more than 250 mm and is characterized by the ability to overcome natural and artificial obstacles such as slopes, slopes, trenches [1]. A distinctive feature of the vehicle under development is the rejection of the internal combustion engine which is the main source of noise in the ATV. The use of ATVs with an electromechanical transmission and a reduced noise level makes it possible to expand the possibilities of carrying out special operations by special-purpose units of the Ministry of Internal Affairs in rough terrain. These vehicles can be used for reconnaissance and covert surveillance, patrolling and combat security, destruction of enemy manpower and combat equipment, target designation; conducting raids in areas where the enemy is deployed, conducting electronic warfare, adjusting artillery fire, evacuating the wounded, blocking difficult areas. As a result of the analysis of the characteristics of ATVs of analogues the requirements for the developed ATV 6x6 with an electromechanical transmission were formed
