Description
Technical field
The utility model is related to automotive suspensions, refer in particular to a kind of riding automobile-used pneumatic suspension.
Background technology
It is well known that automotive suspension can reduce the vibrations and impact that automobile is subject in the process of moving, enable automobile
Safer, comfortable traveling；Automotive suspension uses extensive in the car.The elastic element of existing automotive suspension is usually metal
Spring and air spring；Metal spring rigidity and weight are larger in existing elastic element, increase the overall weight of vehicle body；It is existing
It is made of rubber bag tank and high pressure gas filling equipment air spring.Rubber bag tank rigidity has limitation, fragile, such environmental effects
Greatly, explosive capsule；High pressure gas filling equipment is by dedicated pipeline and compression mechanism at maintenance cost is high, it is big to take up space, influences chassis
Layout.
Utility model content
The purpose of this utility model is that：In view of the above problems, a kind of riding automobile-used pneumatic suspension is provided, this is outstanding
Frame is simple in structure, facilitates installation, while can also reduce the rigidity and weight of support spring, reduces vehicle body overall weight.
The technical solution adopted in the utility model is as follows：
A kind of riding automobile-used pneumatic suspension, it includes air damper and support spring；The air damper includes gas
Support spring is arranged with outside cylinder and piston rod, the cylinder and piston rod, described support spring one end is mounted on cylinder, another
End installation is on the piston rod；The support spring is elongated or shortened along cylinder and piston rod；The support spring is for bearing vehicle
The dead load of body；Air damper is for bearing the shock loading of vehicle body and the dead load of vehicle body.
In above structure, support spring is mainly used for bearing the dead load of vehicle body；Air damper is mainly used for bearing vehicle
The dead load of the shock loading and part vehicle body of body；
Therefore automobile on level road when driving, support spring and air damper provide support force to support vehicle jointly
Body.Therefore the static load support force that spring provides becomes smaller, correspondingly, rigidity needed for spring reduces, weight, vehicle body overall weight
Decline.
When automobile on unstable road surface when driving, the shock loading that vehicle body is subject to pass to air damper and support bullet
Spring；The piston rod of support spring compressive deformation, air damper is subjected to displacement in cylinder, compression cylinder inner space, is generated
Elastic force absorbs shock loading；After shock loading releases, support spring resets under spring force effect, and piston rod is in air pressure
It is resetted under the resilient force that damper generates, while discharging the ability absorbed in shock loading, make the energy in shock loading
It is scattered and disappeared in an atmosphere in the form of thermal energy.
Support spring and air damper absorb the energy in shock loading jointly, and air damper absorbs major part
Energy.
Further, it is installed with spring holder on the cylinder outer wall, activity or spring is installed on piston rod
Platen；Described support spring one end is connected with spring holder, and the other end is connected with spring pressure plate.
Further, it is also equipped with rubber sleeve on the piston rod；Described rubber sleeve one end is used for and spring pressure plate connects
It touches, the other end is used for and vehicle body joint.
Further, the cylinder bottom installs wheel connector.
The course of work of the utility model is as follows：
Cylinder bottom is connected by wheel connector with wheel, and piston rod upper end is connected by vehicle body connector with vehicle body.
Vehicle faces the shock loading that vehicle generates and is transmitted by wheel connector in the process of moving, makes piston rod in cylinder
It is inside subjected to displacement, support spring is made to deform upon；Gas in piston rod compression cylinder generates elastic force and offsets shock loading, branch
It supports spring contraction and generates elastic force counteracting shock loading；After shock loading is offset, support spring is under the effect of support spring elastic force
It resets, piston rod resets under the elastic force effect caused by gas compression.Wherein air damper counteracts in dynamic process
Most shock loading.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1, when driving, support spring provides the static load support force of support vehicle body to automobile balance；Air damper also carries simultaneously
The static load support force of vehicle body is supported for part；Therefore the static load support force that support spring provides becomes smaller；Rigidity needed for support spring
It reduces, weight declines, and reduces vehicle body overall weight；When automobile is by shock loading, air damper counteracts most
Shock loading.Therefore air damper had not only born shock loading that automobile is subject to and but also had born the dead load of part vehicle body；Therefore
When support spring fails, vehicle can also continue to travel.
2, the riding automobile-used pneumatic suspension of the utility model is simple in structure, will not be led as the suspension using air spring
Cause entire suspension frame structure complicated.
3, rubber sleeve is set on piston rod, piston rod is connected by rubber sleeve with vehicle body, and the elasticity of rubber sleeve can be into one
The impact that the counteracting vehicle body of step is subject to, improves damping, the shock resistance effect of entire suspension.
