Description
Technical field
The utility model relates to field of automobile parts and components, in particular to a kind of cross-country fire vehicle Front Leaf Spring.
Background technique
Leaf spring is most widely used a kind of elastic element in automotive suspension, if it is but Length discrepancy wide by dry plate
The spring beam for the approximately equi-strength that the alloy spring piece of (thickness can be equal, can also be unequal) is composed.
When leaf spring is mounted in automotive suspension, and the vertical load born is positive, each spring leaf all stress become
Shape, the curved trend of oriented arch.At this moment, vehicle bridge and vehicle frame are just close to each other.When vehicle bridge and vehicle frame away from each other when, leaf spring
Suffered positive vertical load and deformation is just gradually reduced, sometimes even can be reversed.
Main leaf grasswort stress is serious, is weakness, and for the stress condition for improving main leaf grasswort, second end Chang Jiang is also curved
At grasswort, wrap in the outside of main leaf grasswort, referred to as packet ear.In order to enable in flexible deformation each have the possibility of opposite sliding,
There are biggish gaps between main leaf grasswort and second packet ear.Leaf spring both ends in some suspensions are not made into grasswort,
And other support connection types are used, such as rubber bearing.
The steel plate of flat, rectangular is in Curved, and the chassis spring built up with several pieces, one end is mounted on hanger with mortise pin
On, the other end is connected on crossbeam using lifting lug, makes spring flexible.It is suitable on medium-and-large-sized goods truck at present.
At present in the typical front and back leaf spring structure of automobile, ear-rolling end is ipsilateral at main spring the 1st, i.e., both ends are all upward
(or downwards) bending.Its structure with its simple process, design method is mature, versatile the features such as, adopted by most auto vendors
With.But the leaf spring of current this full symmetrical configuration, when being applied on military 4*4 cross-country fire vehicle, one side can shadow
The water space for arriving fire fighting truck is rung, on the other hand due to water tank heavier-weight beyond the loudness that leaf spring allows, is caused
Security risk.
