SU769142A1 - Shock absorber - Google Patents

Description

concave and intended for contact with an intermediate element in the form of balls o, evenly spaced in the screw grooves 2 of housing 1. Liite grooves 2 can be made, for example, in the form of three-way threads with a shaped profile of the groove, and the moving element d in the form of permanent magnets, installed opposite to each other by the same name and poles, in the case of the necessity of ensuring a constant tension of the elastic coupling system of the shock absorber, the elements 3, which are magnetized cylinders, can be set are opposite poles (Fig. 3). The moving element 3 is connected to the rod 6, which is intended to communicate with the depreciable object, and the housing 1 is rigidly mounted on the movable object 7.

The widths bi and Lg of the screw grooves 2 can be made larger than the diameter of the ball 5 by an amount equal to the maximum allowable movement of the element 3 along the axis of the shock absorber, or equal to the diameter of the ball, in this case the ball 3 is installed in the helical groove 2 of the housing 1, made with a curvilinear shape; her radius equal to the radius of the ball.

The ball 5 can be made entirely m or coated with an elastic material, while the screw groove 2 must be made with a radius equal to the diameter of the ball (Fig. 3).

The widths bi and b2 of the helical grooves 2 and the angle of inclination of the helix are variable.

The shock absorber is assembled as follows. The balls 5 are installed into the concave surfaces 4 of the elements 3 and screwed simultaneously into all the screw grooves 2 of the housing 1. When the balls 5 are made of elastic material to facilitate the assembly of the shock absorber, the case I can be made assembled.

The shock absorber works as follows.

When acting on the rod 6 of external forces, it transmits the movement of the moving element 3 in the form of magnetized cylinders mounted by poles of the same name towards each other. The interaction of the magnets with each other due to repulsive forces leads to the damping of the object connected to the rod 6. The external forces bring the moving element 3 out of balance, causing oscillations about the equilibrium position. At the end of the action of external forces, the moving element 3 in the form of magnets returns due to the action of repulsive forces in the original position. The balls 5 ensure the alignment of the moving element 3 relative to the axis of the shock absorber and limit their reversal,

maintain the distance between the magnets, ensuring the interaction of opposite poles. When the shock absorber is horizontal (Fig. 2) or is set at an angle, the balls do not allow the magnets to move in the transverse plane of the shock absorber due to their own weight force, while maintaining their alignment.

This shock absorber design increases its reliability and extends the scope of

application.
