Embodiment Construction

[0033] In the figures, the same reference signs are used for similar features. In the description, a lateral direction means (transversely and approximately) a direction along an axis perpendicular to the normal direction of travel of the vehicle, ie a direction from one side of the vehicle to the other side of the vehicle. Similarly, a longitudinal direction means (longitudinally and approximately) the direction along the axis of the normal direction of travel, ie the direction from the rear of the vehicle to the front of the vehicle. The longitudinal centerline is an imaginary line located along the longitudinal direction at the transverse center of the vehicle (ie at an equal distance from both longitudinal sides of the vehicle).

[0034] figure 1 A rear suspension 1 of a vehicle is schematically shown, said rear suspension comprising a subframe 2 , a first lower control arm 3 , a second lower control arm 4 and a leaf spring 5 . The subframe 2 is arranged to be attached t...

Abstract

The present invention relates to a suspension for a vehicle comprising a subframe connected to a chassis of the vehicle, a first lower control arm and a second lower control arm connected to the subframe, and a leaf spring, said A leaf spring is mounted transversely in the suspension and is arranged to be connected to the first and second lower control arms and to the subframe. The suspension includes a first spring seat and a second spring seat; the first spring seat and the second spring seat are arranged to be movable along the leaf spring to allow the spring rate of the leaf spring to vary according to the position of the spring seat. A method for adjusting a suspension and a system with leaf springs are also disclosed.

Description

technical field [0001] The present invention relates to a suspension for a vehicle, wherein the suspension includes a subframe connected to a chassis of the vehicle, a first lower control arm and a second lower control arm connected to the subframe. A leaf spring is mounted transversely into the suspension and is arranged to connect with the first lower control arm and the second lower control arm and with the subframe. The invention also relates to a method for adjusting a suspension and leaf spring system. Background technique [0002] Suspensions for vehicles such as cars or trucks often include coil springs of different sizes in order to set the correct spring rate (spring rate) for a particular vehicle. The spring rate of the suspension can be set according to the weight of the vehicle, the vehicle it will be used in, or the driver's preference. [0003] In order to be able to meet the listed requirements, it is necessary to keep several coil springs with different sp...
