Fire fighting service vehicle
First Claim
1. A service vehicle for use as a fire-fighting tanker vehicle comprising an uninterrupted chassis frame carrying a driver'"'"'s cab and supported by four driving axles driven independently of each other by a driving engine, the four driving axles being carried on the chassis frame via pressure fluid springs at opposite sides of the vehicle and the pressure fluid springs associated with wheels at one side being connected via a pressure fluid supply system and a load compensator system to the pressure fluid springs associated with wheels situated at the other side of the vehicle, an automatic transmission situated between front and rear undercarriages each comprising two of said driving axles, the driving axles of each undercarriage being separately coupled to the automatic transmission which is coupled to the driving engine situated on the chassis from above the rear undercarriage, and quenching agent tanks and a quenching agent pump arranged on the chassis.

Abstract
A fire truck comprises an uninterrupted chassis frame carrying a driver'"'"'s cab and supported on four driving axles arranged in 8×8 configuration and driven independently. The driving axles support the chassis frame via pressure fluid springs at opposite sides of the vehicle, the forward and rearward pairs of axles and associated springs defining forward and rearward undercarriages and the chassis carrying quenching agent tanks, a quenching agent pump, and a driving engine. The fluid pressure springs at one side of the vehicle are connected via a pressure fluid supply system and a load compensator system to the springs at the opposite side. An automatic transmission is positioned between the forward and rearward undercarriages and the driving axles are individually coupled thereto. The automatic transmission is coupled to the driving engine which is situated in the chassis frame above the rear undercarriage.

20. A service vehicle comprising a chassis frame supported via spring means by several axles carrying wheels, the axles being carried on the chassis frame by said spring means comprising pressure fluid springs at opposite sides of the vehicle, the pressure fluid springs at one side being connected via a pressure fluid supply system and a load compensator system to the pressure fluid springs associated with the wheels at the other side, an internal tire volume of each of the wheels being connected to the pressure fluid supply system via a tire pressure regulator system, each internal tire volume being associated with a respective regulator valve in the tire pressure regulator system, the tire pressure regulator system comprising relay valves and tire pressure control valves which may be acted upon via separately operated control valve, the tire pressure control valves being placed on the wheels and being equipped with respective shut off elements which interrupt passage through a piping system between the internal tire volume and the associated relay valve via the control valve, the shut off elements having limit means adapted automatically to interrupt if the pressure drops below a minimum tire inflation pressure.
