Embodiment Construction

[0019] A truck with the inventive arrangement is shown in FIG. 1 . The leaf spring suspension device is provided on the front axle of the vehicle. FIG. 1 a shows an enlarged view of the inventive arrangement for suspending leaf springs on a vehicle. The term leaf spring 1 refers to one or more leaf springs 2 made of elastic material such as steel, which have been joined together to form an elastic unit. The arrangement comprises means 3 for suspending a leaf spring 1 on a vehicle, which means 3 is connectable at a first end 4 to the rear end 5 of the leaf spring 1 and at a second end 6 to a vehicle, eg a frame 7 . The rear end 5 of the leaf spring 1 is meant to be the rearmost end with respect to the normal direction of travel 30 of the vehicle. One of generally two bearings 8 , 9 is arranged at the rear end 5 , which is arranged in the longitudinal direction of the vehicle for the rotatable suspension of the leaf spring 1 on the vehicle. The invented arrangement constitute...

Abstract

An arrangement for suspending a leaf spring (1) on a vehicle (7), which arrangement comprises a means (3), which, at a first end (4), is connectable to a rear end (5) of a leaf spring (1) and, at a second end (6), is connectable to a vehicle (7) for suspension of a leaf spring (1) on a vehicle. The suspension means (3) is provided with a built-in weakening (16) so as, in the event of a prespecified loading of the suspension means (3), and when the leaf spring (1) is connected to a vehicle (7) by means of the suspension means (3), to allow the suspension means (3) to collapse while the rear end (5) of the leaf spring (1) is moved rearward substantially past its, in normal running, rearmost position and / or is set free from the vehicle (7).

Description

technical field [0001] The invention relates to an arrangement for suspending leaf springs on a vehicle according to the preamble of claim 1 and to a leaf spring suspension arrangement according to the preamble of claim 18 . Background technique [0002] A sprung suspension for a wheel axle, preferably a leaf spring arrangement for a truck wheel usually has front and rear bearings to suspend a leaf spring assembly arranged between these bearings on the vehicle frame. A leaf spring assembly is rotatably connected to the support. The rear mount typically includes two pivot points and an insert connection that allows the leaf spring assembly to move slightly rearward in the longitudinal direction of the vehicle (and return) when the leaf spring assembly elastically deforms. The leaf spring assembly also has some form of means for connecting the leaf spring and wheel axle together at a location between the front and rear bearings. [0003] Examples of leaf spring devices accor...
