Abstract
A motor-vehicle engine suspension elastic device has a main body of metal and/or composite material elongated in a direction parallel to the longitudinal direction of the motor-vehicle. The elastic device has a first end that can be connected to a structural connecting element of a motor-vehicle, and a second end that can be connected to a motor-vehicle engine. The main metal body of the elastic device includes at least one portion elastically deformable in the aforesaid longitudinal direction.
Claims17
A motor-vehicle comprising:
- a structural connecting element rigidly connected to a front portion of a platform,
- an engine elastically supported on a structure of the motor vehicle,
- an engine suspension elastic device elongated in a direction substantially parallel to a longitudinal direction of said motor-vehicle,
- said motor-vehicle engine suspension elastic device having a first and a second end, said first end connected to said structural connecting element, and a second end connected to said engine, in such a way that, during operation of said motor-vehicle, said engine suspension elastic device reduces the stresses to which said engine is subjected in the longitudinal direction of the vehicle,
- said motor-vehicle engine suspension elastic device having a main body of metal and/or composite material comprising at least one portion elastically deformable in said longitudinal direction with a serpentine wavy conformation defining a plurality of loops with concavities alternately facing in opposite directions, in such a way that said body portion is able to be elastically deformed in said longitudinal direction,
- said body of metal and/or composite material being provided with a number of elements of elastomeric material, each element of elastomeric material being received and vulcanized within the concavity of a respective loop of said elastically deformable portion, for providing elastic and shock-absorbing functions,
- said elements of elastomeric material having at least one hollow portion, to modulate the stiffness of said device.
