ELEMENTS OF THE THEORY OF FLEXIBLE TRANSMISSION OF TRUCKS
Abstract
The working process of woobling of wheeled рушія is accompanied by loading of wheeled wheelby gravitational force that results in a clench and stretch of tire during her deformation. In the article the considered questions of research of the mechanical system “motor-car resilient element reactive push” are with the use of theorem about the change of kinetic energy of this system, general equalization of dynamics, and also equalization of Lagrange the second family. The aim of the study is to improve the technological scheme of loading the wheel drive, converting the energy supplied to the wheel drive into the rotational motion of the spring jet with increasing traction of the car, which is an auxiliary factor to innovative technology of its movement. The scientific and practical direction of work is that for the first time a technology is proposed in which the energy of rotational motion of the mechanical system “car wheel-spring jet” is used to rotate the wheel drive, which allows to increase the realization of torque on the wheel. The methodology of the study was to establish a mathematical relationship between the force generated by a “car wheelspring jet” with the dynamic mobility of the car itself. A research result is the worked out construction of car with a dynamicallymovable platform in the loop of damping a “motorcar wheeledspring reactive push” that works at “physical discomfort of underlayment”. At opening concepts “physical discomfort of underlayment” were used differential equalizations that mathematically confirm the origin of such surface in certain external of car environments. Calculations were performed in an environment EXEL with respects to the relationship between input and output parameters. The results of the research were implemented in graphical dependencies ƞ = ʄ(Ft), dm = ʄ(i), Pt = ʄ(i), Fa = ʄ(Ft), i = ʄ(Ft). The value of the study, the results of this work will contribute to the automotive industry. The proposed car model is suitable for use in order to increase the traction capacity of the vehicle.
