Gegenstand vorliegender Erfindung bildet eine selbstthätige Schutzvorrichtung, . welche verhüten soll, dafs Lastwagen schleudern oder seitwärts gleiten, wie es beim Befahren von Strafsen mit stark gerundetem Profil,' sowie auch bei Waldwegen auf schiefem und unebenem Terrain, im Winter bei Schnee und Glatteis der Fall ist.The present invention provides an automatic protection device. Which is intended to prevent trucks from skidding or sliding sideways, as occurs when driving on Strasen with a strongly rounded profile, 'as well as on forest paths on sloping and uneven terrain Terrain, which is the case in winter with snow and black ice.

Auf beiliegender Zeichnung sind mehrere Ausführungsformen einer solchen Schutzvorrichtung dargestellt.. Dabei ist dieSeveral embodiments of such a protective device are shown in the accompanying drawing shown .. Here is the

Fig. ι die Hinteransicht des Hintertheiles von einem Lastwagen. An jedem Ende der Achse ist eine verschiedenartige Aufhängung des den. Haupttheil . der Schutzvorrichtung bildenden Elementes eines Rades mit Zahnvorsprüngen gezeichnet. DieFig. Ι the rear view of the rear part of a truck. At each end of the Axis is a different type of suspension of the den. Main part. the protective device forming element of a wheel with tooth projections drawn. the

Fig. 2 und 3 sind theilweise Hinteransichten des Hinterwagens, die Schutzvorrichtungs-Ausführungsform auf der linken Seite der Fig. 1 in verschiedenen Stellungen zeigend. DieFigures 2 and 3 are partial rear views of the rear carriage, the guard embodiment on the left side of Fig. 1 in different positions. the

Fig. 4 ist ein senkrechter Schnitt, quer zur Achse genommen, ebenfalls diese Ausführungsform zeigend. Die Fig. 4 is a vertical section, taken transversely to the axis, also showing this embodiment. the

Fig. 5 und 6 stellen eine zweite Ausführungsform des erwähnten Rades dar, bei welcher die Zähne durch eine Schneide ersetzt sind. Dabei ist die Fig. 5 eine Seitenansicht, die Fig. 6 theils Vorderansicht, theils Querschnitt.Figs. 5 and 6 show a second embodiment of the mentioned wheel, in which the teeth are replaced by a cutting edge. 5 is a side view showing Fig. 6 partly front view, partly cross-section.

Mittelst der Bänder α werden von unten her gegen die eiserne Achse b Schienen c bezw. c¹ geschraubt, welche mit einem Augec², rechte Seite der Fig. 1, bezw. mit zwei unter einander liegenden Augen c^s cⁱ ausgerüstet ist (linke Seite dieser Figur). Die Augen c^s c⁴ ermöglichen nun, zwei Stangen d¹ d'² gelenkig mit der Schiene c^l zu verbinden, wobei diese Stangen andererseits an einem U-förmigen Bügel e ebenfalls gelenkig angeschlossen, sind. Vorausgesetzt nun, dafs die Stangen d¹ d'² von gleicher Länge sind und ebenso der Abstand der Augen C³C⁴" gleich ist demjenigen der Augen e¹ e² des Bügels e, so entsteht ein Parallelogramm, welches ermöglicht, dafs sich der Bügel parallel zu sich „selbst bewegt. Dabei ist die Anordnung eine derartige, dafs diese Bewegung des Bügels e in einer_ senkrechten, zur Achse b parallelen Ebene stattfindet. An ihren freien Enden sind die Schenkel des U - förmigen Bügels e mit Augen e ³ ausgerüstet, welche <— einander gegenüberstehend — von einem Zapfen/ durchsetzt werden. Der letztere durchsetzt aufserdem die Nabe eines Rades g, dessen Reifen der Fig: 1 gemäfs mit Zinken h ausgerüstet ist.Middle of the bands α are from below against the iron axis b rails c respectively. c ¹ screwed, which with an Augec ² , right side of Fig. 1, respectively. is equipped with two eyes c ^s c ⁱ lying one below the other (left side of this figure). The eyes c ^s c ⁴ now enable two rods d ¹ d ' ^{2 to be connected in an} articulated manner to the rail c ^l , with these rods on the other hand also being articulated to a U-shaped bracket e. Provided that the rods d ¹ d ' ^{2 are} of the same length and the distance between the eyes C ³ C ⁴ "is also equal to that of the eyes e ¹ e ^{2 of} the bracket e, a parallelogram is created which enables the The bracket moves parallel to itself. The arrangement is such that this movement of the bracket e takes place in a perpendicular plane parallel to the axis b . At their free ends, the legs of the U-shaped bracket e are equipped with eyes e ³ , which <- opposite one another - are penetrated by a pin I. The latter also penetrates the hub of a wheel g, the tire of which is equipped with teeth h as shown in FIG.

Auf der rechten Seite der Fig. 1 ist
ebensolches Rad g mit U-förmigem Bügel e vorgesehen, die Beweglichkeit des letzteren in einer senkrechten, zur Achse b parallel laufenden Ebene wird jedoch dadurch ermöglicht, dafs sein Arm eⁱ unter Benutzung des Auges c'² an die Schiene c angelenkt ist.On the right side of FIG. 1 is
provide such a wheel g of U-shaped bracket e provided, the mobility of the latter in a vertical, b parallel to the axis current level is, however, possible by his arm e ⁱ DAF using the eye c ^'2 is articulated c to the rail.

Die in der einen oder anderen Weise, wie beschrieben, aufgehängten Räder e stimmen in folgender Hinsicht überein. The wheels e suspended in one way or another as described are the same in the following respects.

Beide zeigen — mit dem dieselben stützenden Bügel e als. Schwinge aufgepafst — von dem Drehpunkt bezw. den Drehpunkten aus nach innen, sobald sich der Lastwagen auf ebener Strafse bewegt. (Fig. 1), und die Räder g rollen auf dem Boden oder Pflaster, ohne in Wirkung zu treten. Zeigt jedoch der Lastwagen dasBoth show - with the same supporting bracket e as. Swing arm watched - from the pivot point respectively. pivot points inwards as soon as the truck is moving on a level street. (Fig. 1), and the wheels g roll on the ground or pavement without having any effect. However, the truck shows that

Claims

Endeavor to slide sideways, for example in the direction of the arrow Fig. 2, i.e. to the right, then the prongs h of the left wheel g engage in the ground or the pavement and the rocker d1 d'2 eg moves so far outward, until it is determined by its stroke limitation, for example a chain i connected to the axis b (position FIG. 2). Then the prongs h of the wheel g act as an inhibition in relation to the lateral movement of the truck, the truck being raised slightly on the side of the swing arm that has come into effect. If the truck slides sideways in the opposite direction, the second rocker arm e4 e g comes into action. To avoid the swing dl d'2 e g respectively. e4 e g to the rear, a fork k is pushed onto each of the pegs f, which is coupled to the rear carriage by means of a chain / (Fig. 1 and 4) running forward (Fig. 4). From FIGS. 1 and 4 it can also be seen that the lower c4 of the eyes cs ci can be used to connect a stiffening rod m which, on the other hand, is screwed to the rear axle timber. Finally, with reference to FIG. 3, it should be mentioned that the rockers d1d "2eg or e ^ eg can be set to work by using a hook η to shorten the chain / serving as the stroke limiter, namely instead of the ring n1 one of the links of this chain located in the vicinity of the attachment point on the bracket e is suspended on this hook η Roll this wheel more evenly over the ground and offer more contact surface than the above-mentioned tips, especially on stuck, smooth snow tracks. Instead of a tire with a T-shaped cross-section, a tire made of angle iron can also be used To facilitate the tines h or the cutting edges 0 with the ground, arrange the rockers so that they can rotate forwards instead of in the vertical plane through the axis and inwards s up. to · turn. You can also move the points of support of both rockers in the middle of the axis and assume that they point outwards instead of pointing inwards when they are not in use. Patent claim: A device for preventing sideways sliding or skidding of penalty vehicles, characterized by wheels fgj, which are suspended from the car and provided with points (Ji) or cutting edges (0) on the running surface and which touch the ground and are perpendicular to the longitudinal axis of the car can swing lying plane, for the purpose of preventing sideways sliding by cutting the wheels (g) into the roadway and thereby lifting one side of the car. For this 1 sheet of drawing pieces. The rail η1 of FIG. 6 is replaced by two spikes k k, toothed corresponding to the cross-section of the connecting tires, on which the locking piece ρ pl slides in the manner already described. Should the tiles on the. wheel rim provided with edge projections ν U-shaped cross-section (Fig. 13) are attached, the associated plates A, as shown in the same figure, must be shaped accordingly on their underside in order to join the U-shaped profile of the wheel tire. If segments produced by pressing are to be applied to a wheel rim with a dovetail-shaped cross section, the tire can be produced from two longitudinal parts v1 v'2 joined by screws vs, as shown in FIG. 14; in this case the unification of the segments can be omitted by tires or rings stored in their interior, in that the wheel tire itself holds the plates in the necessary position. Finally, it should be mentioned that the plates do not have to be positioned normally against the wheel tire, but can also have a slight inclination towards it, as the wheel segment shown in FIG. Patent Claims:

1. An embodiment of the press, protected by patent no. 81017, for the production of wheel tires from small edged plates placed side by side, characterized by an insert made of a base plate (s) with a toothed guide rail (Ti ¹ J, on which cover plates (pp ¹ ) slide and are locked by pawls (q) under spring pressure, for the purpose of being able to remove the segments consisting of compressed plates with the closed insert from the prefscylinder.

2. An embodiment of the under 1. marked Press, in which the cylinder and piston are straight, for the purpose of creating cylinder-shaped segments. to obtain, which only receive the necessary bend when they are applied to the wheel rim.
