CZ2905U1 - Device for softening characteristic of a springing element - Google Patents

Description

A conventional spring element used to vaccine two bodies would change, increase or increase the binding force during the relative movement of the bodies. The magnitude of the change in the binding force depends on the characteristic of the spring element, its angularity and the magnitude of the movement of the bodies.

Softening of the characteristic of the spring element is known for roasting a rail vehicle. In comto, the elastic and compensating elements form two separate units, adding: the compensating element is construc- tively complex. January, the load of the spring element in the wagon body, under heavy loads,

These drawbacks are largely eliminated by the device for softening the characteristics of the spring-loaded load-bearing element, which is based on the fact that at least

a bracing rod is provided, which is supported by its orbital kc-ncsm in the seat of the spring element.

The device for softening the characteristic of the spring element allows compensation of the increment of force of the prestressed spring element by means of a compensating element with negative stiffness. Compensation for the increase or decrease in binding force may be partial, total, or overcompensated. Practically this means that the device softens the characteristic of the spring element whose curvilinear shape is caused by a change in the contact force in the compensating part of the zen i.

The device for softening the characteristic of the spring element is structurally very simple.

The technical solution is explained in more detail in the accompanying drawings, in which it is shown in an assembly state, wherein in Fig. 1 there is an asymmetrical solution comprising one compensating element, in Fig. 2 there is symmetrical speech containing two compensating elements. 1 and 2 can be used for tensile force. The device can be designed also for compressive force, respectively for tensile and compressive force, in which cases the device would be larger. Fig. 3 shows the characteristics, wherein curve 1 is the spring element characteristic, curve 2 is the softening characteristic of the spring element as the spring element increases, the curve 3 of the partial compensation device softening characteristic is the spring element characteristic and a characteristic curve in total compensation of the spring force increment

The device performs its function up to the relative motion irr <e v <Za.

The asymmetrical device is dimensionally more advantageous than the symmetrical device, but its disadvantage is the possibility of wear of the functional parts; in this case, the device could also be used for damping oscillations by dry friction.

The symmetrical device is more space-intensive, but there is no wear of the functional parts.

The device for softening the characteristic of the spring element can advantageously be used wherever the characteristic of the spring element does not meet the desired purpose. \
