Abstract
A leaf spring suspension includes a plurality of leaf springs fixedly secured together by a bolt in the form of a stack. A first leaf spring of the plurality of leaf springs has ends configured to be coupled to a vehicle frame. A pin extends through each leaf spring except for the first leaf spring to prevent splaying between the leaf springs during transverse loading of the suspension.
Claims20
A vehicle suspension comprising:
- a plurality of leaf springs each having a generally rectangular cross section, each leaf spring having opposite ends and a middle section extending therebetween, the middle sections of the leaf springs being clampingly secured to each other so that the leaf springs form a stack, a first leaf spring of the plurality of leaf springs having ends adapted to be coupled to a vehicle frame;
- and
- a pin extending through each leaf spring other than the first leaf spring for preventing separation between the leaf springs and for minimizing stress concentrations in the first leaf spring during loading of the vehicle suspension.

- a first leaf spring in the stack having ends adapted to be pivotally coupled to a vehicle frame,
- a second leaf spring in the stack being disposed adjacent the first leaf spring, a hole being formed in a side of the second leaf spring opposite the first leaf spring and extending through a portion of a thickness of the second leaf spring,
- each leaf spring other than the first and second leaf springs having a bore extending therethrough;
- and
- a pin extending through the bores of each leaf spring and into the hole of the second leaf spring for preventing separation between the leaf springs and for minimizing stress concentrations in the first leaf spring during loading of the vehicle suspension.
