  • the emergency spring is usually mounted on the chassis side or on the rim, which in turn is mounted on the auxiliary spring.
  • primary suspension / primary suspension system and "secondary suspension / secondary suspension system” which are sometimes used with some fuzziness are basically very simple to define as follows:
  • Primary suspension in today's vehicles means the first and basic suspension between the unsprung wheel mass and the chassis or axle beam of a vehicle In a car or truck, this primary suspension is provided by the resilient properties of a pneumatic tire, ie the pneumatic tire the "primary spring”.
  • Primary suspension usually consists of material- or form-elastic components, such as coil springs, leaf springs, rubber-metal springs, etc. and is usually designed for the suspension of high-frequency loads. This is also common in modern wheels, which are constructed to reduce noise from an inner wheel disc, a surrounding rubber element and finally an outer rim.
  • this secondary suspension is used achieved by damped steel springs, air springs or struts between chassis and body.
  • the air spring with additional volume also serves, for example. the load-dependent height regulation and is designed for low-frequency loads.
  • the regulation of the driving level is usually carried out by the secondary suspension taking into account the total height or the total spring travel of the

  • the additional spring is designed as a block spring made of rubber and largely surrounded by the air spring.
  • the additional spring is also arranged so that the car body can sit on an air spring in the air spring on the same time designed as an emergency spring auxiliary spring.
  • the additional volume is formed in the air spring cover and the emergency spring is arranged facing the inside of the air spring cover and the chassis-side rim.
  • the emergency spring comes only when the air bag is depressurized and no longer carries the car body. Then the top plate is located with the emergency spring on the rim of the auxiliary spring. The emergency spring then takes over the support function together with the additional spring and thus influences the vertical characteristic. Due to the mounting position on the underside of the top plate greater horizontal deflection of the top plate to the lower auxiliary spring wall without contact Balginn and preloaded spring element in emergency spring and air spring operation can be enabled. Narrow curve passages of the rail vehicle, even at higher loads, can thus be realized.
  • the emergency spring is provided on the inside of the air spring cover with a bias.
  • the bias allows a reduced installation height of the emergency spring and thus an often desirable reduced height of the air spring system.
  • the fact that the top plate is connected to the car body, also the emergency spring is exposed to only small vibrations and accelerations in contrast to the usual in the art mounting the emergency spring on the rim / on the auxiliary spring.
  • the screw connections are therefore subject to lower force influences in the construction according to the invention. It is only that weight of the additional spring connected to the chassis or with the bogie, whereby the unsprung mass is reduced.
