Introduction to the experimental table

The vehicle transmission system is an important part of the vehicle's overall, with complex structure and diverse forms. In particular, the typical dual transmission systems of modernity, such as zero difference, positive difference, negative speed, positive independence, zero independence, negative independence, and work principles. The characteristics of wheeled vehicles are the key to understanding the principle of driving of the belt -type vehicle and the design ideas of the transmission system. It is only relying on classroom learning and abstract content, which is not conducive to students' in -depth understanding and mastery. Through the construction of this experimental desk, we will strengthen the tr--ning of the innovative design and experimental links of the student tracking vehicle transmission system, to cultivate students 'practical ability and innovative awareness, and at the same time deepen the design and principles of students' understanding of the driving system of the band -type vehicle.

The function of this experimental table is m--nly to provide students with a tr--ning platform for the structural design and control of the zero -differential dual -drive system, allowing students to be proficient in the design of the overall structure and control scheme of the dual -drive system, including the diversion/exchange mechanism scheme, the transmission change Institutional solutions, steering institutional solutions, etc.

Second, the experimental table structure

1 -turning motor, 2 -left corner position sensor, 3 -left wheels, 4 -left -wheels beside the deceleration gear, 5 -left turn differential wheel system, 6 -transmission gear gear mechanism, 7 -right turn to differential wheel system , 8 -reduce gear by the right wheel, 9 — right wheels,

10 -right corner displacement sensor, 11 — m--n motor, 12 -m--n transmission belt, 13 -protagonist displacement sensor, 14 -steering corners, 15 -steering drive belt, 16 -control panel, 17 -base base

The experimental desk is m--nly composed of a base, a gear shifting gear mechanism, a steering mechanism, a zero -differential diversion/exchange mechanism, and a left and right wheel transmission system. The rotation of the wheels is m--nly driven by the m--n motor 11, and the transmission of the simulation vehicle is achieved through the gear shifting gear mechanism 6; the rotor of the steering motor 1 is different from the left and right turbine system 5 and 7. The turning of the vehicle.
