Description

The rubber suspension of engineering truck propons
Technical field
The utility model relates to the rubber suspension device that a kind of engineering truck propons uses, and belongs to suspension device for vehicle
Technical field.
Background technology
Suspension system is one of important component part of vehicle, it flexibly couples together vehicle frame (or vehicle body) and vehicle bridge (or wheel), and bear application force between them, the shock-excitation of vehicle frame (or vehicle body) is passed in mitigation by the road surface, decay is owing to the vibratory response that encourages the bearing system that causes, have only well behaved suspension system, could guarantee that automobile has good riding comfort, road-holding property and safe reliability.
Because engineering truck axle load unloaded and at full load differs greatly, and has metastable suspension natural frequency and good ride comfort for keeping car load under different loads, this just requires suspension system to have good nonlinear characteristic.And present engineering truck generally adopts the leaf spring suspension, and the rigidity of this structure is linear, and its natural frequency changes with load change, if realize the non-linear of suspension rate by increasing auxiliary spring, the nonspring carried mass of suspension will increase, and makes vibration strengthen, and reduces vehicle ride comfort.
In recent years, non-linear suspension systems such as hydro pneumatic suspension, air suspension and rubber suspension are applied in engineering truck gradually.Hydro pneumatic suspension is made up of hydro-pneumatic spring and guiding mechanism.Hydro-pneumatic spring has the characteristic that becomes rigidity, can make vehicle obtain lower natural frequency, to guarantee good riding comfort.In addition, owing in the hydro-pneumatic spring cylinder barrel damping hole is arranged, the function that stops vibration is arranged, so can save liquid damper.But hydro-pneumatic spring manufacturing cost height, and need the special inflatable appliance of a cover in using, and will regularly put on the air by certain operating instruction, maintaining is trouble.Simultaneously, at work because of the deflection and the poor sealing of oil cylinder axis, the easy scratch of oil cylinder inner surface.
The main elastic element of air suspension is an air bellow, and this spring also has the stiffness variable elastic behavior, obtains lower natural frequency easily, makes vehicle obtain good riding comfort.But air bellow is compared with rubber spring, and sealing part is more, easily gas leakage, and maintaining difficulty, volume are big, difficult arrangement.Relatively air and hydro pneumatic suspension, rubber suspension have the pressurized air of not needing, do not need related electric equipment, simple in structure, easy for installation, from advantages such as heavy and light, corrosion stability, endurances.
Summary of the invention
Technical matters: the utility model technical issues that need to address provide a kind of rubber suspension that can be used for the engineering truck propons, can guarantee to have metastable natural frequency, make vehicle have good riding comfort and stability at the different loads lower suspension.
Technical scheme: the rubber suspension of engineering truck propons of the present utility model lay respectively at the vehicle propons both sides, the rubber suspension of each side comprises elastic joint bearing, coupling block, wishbone, bearing, stay bearing plate, energy disperser, rubber spring, rubber pad, shock absorber, resilient bushing, sleeve; Wherein, rubber spring, energy disperser, shock absorber are arranged in the vehicle frame outside, two rubber springs are about symmetry before and after the vehicle bridge axis, energy disperser and shock absorber lay respectively at the front side and the rear side of rubber spring, rubber spring links to each other with stay bearing plate with vehicle frame respectively with the energy disperser upper and lower side, on vehicle bridge, the shock absorber two ends link to each other with wishbone with vehicle frame respectively by bolted connection for stay bearing plate and bearing; The wishbone front end is connected on the vehicle bridge, and it is hinged that elastic joint bearing and coupling block and vehicle frame are passed through in the rear end; Lateral rod is positioned at the rear side of vehicle bridge, and lateral rod one end is hinged by resilient bushing and sleeve and vehicle frame, other end green phase with structure and wishbone hinged.Wishbone adopts the wishbone in I-shaped cross section, and lateral rod adopts the straight tubular lateral rod.
Beneficial effect: the utility model is because the employing rubber spring is a suspension master elastic element, and form guiding mechanism by the wishbone and the straight tubular lateral rod in I-shaped cross section, have simple in structure, from heavy and light, the suspension parts are stressed rationally, even and the numerical value of stressed member distribution of stress less and fatigue life of advantage of higher, can guarantee to have metastable natural frequency at the different loads lower suspension, make vehicle have good riding comfort and stability, be suitable for use as engineering truck propons rubber suspension.
