### Primary

###### SUSPENSION

##### Primary Suspension

##### Adapted to LRVs, Trams, Metros,
Regional & Intercity trains

##### Provides vertical suspension and damping to the bogie and also gives guiding of the axle in longitudinal and lateral directions.

They also assure homogeneous distribution of loads on the wheels, which is crucial to assure brake and traction performance and to avoid the risk of derailment

**Customer benefits**

### Secondary

###### SUSPENSION

##### SecondarySuspension

##### Adapted to LRVs, Trams, Metros, Regional, Intercity & High-Speed trains

##### Its function is to connect the bogie with the car body to assure passenger
comfort.

It is responsible for train stability in curves and during starting and braking.

It must ensure high flexibility in all directions.

It is composed by a rubber below, an emergency spring, and sliding plate and the top and bottom metal parts.

### Motor and gearbox

###### SUSPENSION

##### Motor and Gearbox

##### Content in Development

##### Coming soon to help you explore Wabtec solutions and expertise

### Elastic wheels

###### SUSPENSION

##### Elastic Wheels

##### Adapted to LRVs, Trams & Metros

##### Elastic wheels offer smoother and quieter rides, they minimise wear on all types of trams, LRVs and metros, giving primary suspension to the system.

##### Elastic & Hyperelastic wheels suspensions are in our scope.

##### EPDM compounds are used as the best solution in terms of relaxation and fatigue.

### Sensorized springs

###### SUSPENSION

##### Sensorized Springs

##### Adapted to LRVs, Trams & Metros

##### The main purpose is to acquire more knowledge of the mechanical performance of a primary spring in a real service operation during the time.

##### Sensors at the axle level for the 3 directions (vertical, lateral & longitudinal).

##### Accelerometers and displacement measurements between bogie and axle box for validation of the optical sensors, including GPS.
