Definitions

  • the task of the springs is to-take up the forces which on running over inequalities of the road produce an acceleration of the unsprung masses.
  • the sprung masses takeup the goods being conveyed or in thecase of passenger 'vehicles'they support the passengers. The steadier the sprung masses behave whilst running the more pleasant is the journey to the passenger, and awell or badly sprung vehicle is generally spoken of.

  • the screw cap 33 is provided with a hole 34 through which reserve oil can be filled in.
  • the conduit 35 represents the connection with the reserve oil chamber 36 which is closed by a ball valve 31.
