Continuously variable transmission box and operating method therefor

Abstract

The invention relates to a continuously variable transmission (1) comprising a driven rotary part (2), a chassis (4) or housing, and a driving rotary part (3). The invention also relates to an associated operating method whereby the driven rotary part (2) or the chassis (4) or housing is coupled to a first guide or drive module (5,5'). A second guide module (14) is also provided, the two guide ordrive modules (5,5', 14) being connected to a chassis (4) or housing of the transmission (1) or an adjacent machine or installation part, such that the second guide module (14) can be displaced in relation to the first guide or drive module (5, 5'). Furthermore, the two guide or drive modules (5,5', 14) are coupled to each other by means of at least two mechanisms, each consisting respectively ofa first coupling module (7a-7d) and a second coupling module (8a- 8d) which are mounted (9a-9d) or guided against each other and / or can mesh with each other. A transport displacement of the deflection angle omega of the rotary displacement of the first or second coupling module (7a-7d, 8a-8d) in question is cyclically transferred to another rotary part (18), and the rotary axes of the rotary connections of a free wheel (16a-16d) are aligned.

Description

technical field [0001] The invention relates to a continuously variable gearbox and a method for transmitting relative rotational movement between at least one first rotating member (in particular a first transmission shaft, ring or cylinder) and a chassis or housing to at least one first rotating member. The method on the second rotating member (especially the second driven shaft, ring or cylinder). Background technique [0002] A device that converts speed and torque is usually called a gearbox. These gearboxes can transform the torque and rotational speed provided by the transmission into different torques or different rotational speeds or rotational speed / torque combinations. [0003] Such a gearbox can be designed as a variable-speed gearbox or as a continuously variable transmission, wherein the variable-speed gearbox has at least one predetermined transmission ratio, but the transmission ratio of the continuously variable transmission can be continuously varied withi...

AI Technical Summary

Problems solved by technology

Since the toggle lever is thus not free from external forces but becomes an integral part of the energy transfer, the mechanism is not only very complex but also prone to failure

Because the slightest deformation of the wings or guides can cause the detent to not work precisely

Finally, the adjustment range of the two gearboxes mentioned above is rather small, since the additional maximum speed achievable on the driven shaft with the synchronous speed corresponds to only a fraction of the transmission speed
