Continuously variable gearbox controlled as a function of load, for internal combustion engines
Continuously variable gearbox controlled as a function of load, for internal combustion engines, with the following principle of operation: lever: driving bevel gear Z = power arm, power-transmitting bevel gear Z1-Z2 abutment, driven bevel gear Z3 work arm; and the following conditions of operation: uniformity in the direction of rotation of the driving gear Z and the driven gear Z3, produced by laterally reversed arrangement of the driving gear Z with respect to the power-transmitting gear Z1-Z2. Ratio of the driving to the power-transmitting gear = 1 : 1; and with the following function: the transmission ratio, which can be selected by means of the construction of the gearbox, can be overridden spatially by the power-transmitting gear by virtue of its construction and, in terms of value, by virtue of its 1 : 1 ratio with respect to the driving gear and its mounting in two planes. Its radial rotation gives a ratio of 1 : 1 between E and A. Its axial rotation gives a ratio of Z : Z3 between E and A. The radial rotation can be influenced with rotation in the same direction since Z and Z3 rotate in the same direction, in a neutral manner via Z since it is in a 1 : 1 ratio with the power-transmitting gear, and in a variable manner by Z3 since the operative ratio is Z : Z3, taking into account that radial + axial = E. Since a relief of the load on Z3 means a reduction loading of Z3 and means an increase in power transmission, load-dependent control is obtained.
