Abstract
The article provides a review and analysis of the current state of development of 4x4 ATVs and the scope of the developed ATV, a comparison of ATVs with mechanical and electromechanical transmissions, as well as their technical characteristics. The selection and justification of the design solutions for a 4x4 ATV with an electromechanical transmission are given on the basis of the following electric drive schemes considered in the article: “Electric motor instead of ICE”, “Motor axis”, “Electric motor-half axis”. The general design solutions of the ATV being developed is also presented based on the selected electric drive scheme.
Highlights
The article provides a review and analysis of the current state of development of 4x4 ATVs and the scope of the developed ATV, a comparison of ATVs with mechanical and electromechanical transmissions, as well as their technical characteristics
A distinctive feature of the developed vehicle is the rejection of the internal combustion engine, which is the main source of noise in the ATV
The requirements for the characteristics of the developed ATV were formulated on the basis of an analysis of the technical level of ATVs of a similar class presented on the market with both mechanical and electromechanical transmissions, the design of which is devoted to the work [4]
Summary
Dimensions, mm Wheelbase, mm Weight (dry), kg Payload, kg Seating accommodat ion Engine, qty. The scheme has the following advantages: 1) the presence of free from mechanical elements of the driveline design solutions space between the axes; 2) the ability to implement individual axis control algorithms without the use of mechanical devices; 3) the possibility of implementing "complex" types of movement, such as a u-turn It has the following disadvantages: 1) to ensure the possibility of movement on the rise, sloping and when traveling over rough terrain, it is necessary to use oversized electric motors, as well as oversized traction inverters; 2) a large mass of electrical equipment on board: 4 electric motors, 4 inverters, a large number of wiring; 3) an electrical system with a maximum number of electrical components will lead to a general decrease in the reliability of an ATV; 4) one posted wheel will lead to a loss of a quarter of the total power of the ATV; 5) a more complex branched cooling system for four electric motors.
