DE411161C - Vehicle suspension - Google Patents

Description

The present invention represents and distinguishes a new cushioning for vehicles differs from the common springs or spring systems in that the suspension becomes harder with increasing load on the system.

With the same hardness of the spring action, each spring or each Federsysteffl significantly more uncomfortable when the car is empty

ίο produce effects than when the car is occupied, which is explained by the different sized effective masses. So to be one as possible To achieve a similar spring effect for all loads, the cushioning must be soft when the car is empty and with increasing Load become harder.

There are springs known in which with the help of a support shoe or by two located within the suspension points

ao borrowed adjustable supports the hardness of the springs can be influenced. These; However, statements do not correspond to the subject matter of the invention as it does not have a continuous, variable and automatic setting ensure the spring action with changing loads, which is a requirement is fully complied with with the subject matter of the invention.

Fig. Ι of the drawing shows the object, of the invention when the vehicle is unladen, Fig. 2 when the vehicle is loaded.

On the bogie frame α the links b lund to this the link c imid d are deflected, around which the latter the spring / is hinged. The same is loaded by the pendulums, which are hinged to the cradle g and through the intermediary of the same, the weight of the car is transferred to the spring /, in such a way that with increasing or decreasing load due to the change in the lever arm χ caused by the rolling of the pendulum e the constant changeable. Spring effect is achieved. To the cradle g against rolling off the sides of the spring /

To secure it, it is to be connected to the links b, d by the link c in such a way that when the cradle moves sideways, the links d, b are brought out of their vertical position and thus result in a restoring moment. The links b, d can also be replaced by a chain.

The spring / must now have such a curvature that it has ^{an upward curvature when the vehicle 1 is} empty and a downward curvature of the same size as possible when the vehicle is loaded *. The first case results, as Fig. Ι shows, a large, effective lever arm χ of the spring, while in the second case (Fig. 2) this lever arm is reduced to the dimension>', ie the spring became harder in its effect.

Of course, the application of this principle is not limited to bogie vehicles, but can be used in a different structural design for every type of vehicle.

Claims (2)

Patent Claims: ι. Vehicle suspension, characterized in that the load is transmitted to a spring (/) supported in the two end points by two pendulums iß) in such a way that the lever arm (x) , which is large and effective when the vehicle is unloaded, is caused by the increasing or decreasing load The rolling of the pendulum (e) is subject to a constant change, whereby a uniformly variable spring effect corresponding to the load is achieved. 2. Vehicle suspension for bogie wagons according to claim r, characterized in that the spring (/) is suspended in chains or chain-like hanging straps (b, d) to which the link (c) hinged to the cradle (g) are hinged to the To limit the movement of the cradle (g) sideways or to dampen the latter.
