Abstract

The invention relates to an axle suspension for a toy vehicle. The aim of the invention is the elimination of functional defects known technical solutions while improving the economic producibility. According to the invention, the object is achieved by providing two each angled levers (3), which are movably mounted with their one end in the corners (8) of the vehicle frame (2) and with its angled end on a spring axis and under bias standing compression spring (4) on the spring axis between the angled ends of the lever (3).

Field of application of the invention

The invention relates to an axle suspension for a toy vehicle. Special field of application is the toy vehicle industry.

Characteristic of the known state of the art

Various axle suspensions of toy vehicles are known from the prior art. Thus, in DE-OS 1961956 a Achslagerung including suspension, which is achieved by a fixed to the vehicle frame leaf spring-like component is described. The suspension is in contrast to an uncomfortable and unsuitable for demanding toy vehicles solution.

In DE-OS 1902231 a suspension for model vehicles is described of spring wire, which does not seem suitable for toy vehicles of larger design, since in the present construction, the correlation between high projected axle load and minimal spring action or vice versa.

The applicability of both technical solutions is characterized by the limitation that the components for the

Achieving the spring action located above the vehicle frame, and thus an unrealistic transfer of the appearance of a production vehicle is carried out on a toy vehicle model.

Furthermore, it is known to form the bearings of Hinterradacl.jen as long holes (DE-AS 1008630).

Object of the invention

The object of the invention is to provide an axle suspension for toy vehicles, which eliminates the functional deficiencies of known technical solutions, is economical to produce and includes a high play value.

Explanation of the essence of the invention

The invention is based on the object, located below the toy vehicle frame, responsive to any unevenness axle suspension with a comfortable as possible, i. develop soulful spring action, the items can be combined with a low installation cost and still the greatest possible security for the captivity of the items is given in event of game overloads arising. According to the invention, this object is achieved in that two angled levers are provided in each case 3, which are gelsgert with its one end in the corners of a vehicle frame and with its angled end on a spring axis and this movable movable unc 'a biased compression spring on the spring axis and this enclosing between the angled ends of the lever is located.

The compression spring located on the spring axis and under bias transmits its fader force at its end faces on the angled end of each lever and the resulting lever position on the spring axis, the ends of each in a known per se, advantageously as a slot, formed breakthrough within the vehicle frame , is transmitted. It can, in particular in non-steerable rear axles of toy vehicles, 'Jie function of the spring axis are integrated into the function of the wheel axle, so that said compression spring is located directly on the wheel axle. In articulated wheel axles, a steering linkage can be arranged parallel to the spring axis, which is connected via a split axle and a link with the Fuderachse. A sensitive Federw.'rkung the entire spring system is achieved by a coordinated sizing of compression spring, lever design and slot design. The captivity of the items of axle suspension is thus ensured that all items of the axle suspension form-locking and holding on the Fedorachse (the spring axis enclosing) are arranged.

embodiment The invention will be explained in more detail with reference to an embodiment. Show it Fig. 1: the view einar Achsfederung transverse to the direction of travel in the unloaded state FIG. 2 shows the view A of the axle suspension indicated in FIG. 1, the representation of the wheels being omitted Fig. 3: the view of an axle suspension transverse to the direction of travel in one-sided loaded condition, the dio representation of HäHei

is weggelaasen Fig. 4: the view ai axle suspension transverse to the direction of travel in evenly loaded condition, woboi the representation of

Wheels is omitted Fig. S: the view of an axle suspension transversely to the direction of travel in the unloaded state in combination with a steerable wheel axle.

Figures 1 to 4 represent a nichtanlenkbare axle suspension, in which the wheel axle 1 at the same time the function of Spring axis 10 Fulfilled in FIG. As is apparent from Figures 1 and 2, the axle suspension is exemplified by the components wheel axle 1, vehicle frame 2, Lever 3 and compression spring 4 together. The storage of the wheels 5 on the wheel axle 1 is not shown in detail. The compression spring 4

is under a defined bias and transmits thereby at their end faces 6 their spring force on the two levers 3, which are structurally designed so that they dio wheel axle 1 arranged on both sides of the lower edges of the vehicle frame 2

Press long holes. In this case, by way of example, the pivot points 8 of the levers 3 can be found in the by bending the side legs of the vehicle frame

arising corners.

In Figure 3, the maximum spring angle α of the wheel axle 1 is shown. It occurs when the vehicle or the vehicle Vehicle axle is loaded on one side, d. H. Due to the unilateral axle load, the wheel axle 1 is diagonally between Upper or lower edge of the slots 7, wherein the angular movement of the wheel axle via the pivot points 8 of the lever 3 on the End faces 6 of the compression spring 4 is transmitted and thus damped. Figure 4 shows an analog axle suspension with uniform axle load, so that the wheel axle at the upper edges of the two Long holes 7 is applied and selbiger the spring travel a was covered. Figure 5 shows an embodiment of a steerable vehicle axle, which consists essentially of a split articulated Wheel axle 9, a spring axis 10, the two connecting links between the spring and wheel axle 11, the steering linkage 12th

and the components already described compression spring 4, lever 3 and vehicle frame 2 consists. Here, the spring action is analogous to Figures 3 and 4, wherein the suspension between the wheel and spring axis is transmitted through the connecting member 11.
