Abstract
A pressure vessel system for a motor vehicle comprises a plurality of pressure vessels for storing fuel. The pressure vessels are generally provided in the underfloor region of the motor vehicle, and the longitudinal axes of these vessels are expediently parallel to one another. At least one pressure vessel of the plurality of pressure vessels is a reinforced pressure vessel. At least one other pressure vessel of the plurality of pressure vessels is a reinforcement-free pressure vessel.
Claims9
A pressure vessel system for a motor vehicle, comprising:
- a plurality of pressure vessels for storing fuel, wherein at least one pressure vessel of the plurality of pressure vessels is a reinforced pressure vessel, wherein at least one other pressure vessel of the plurality of pressure vessels is a reinforcement-free pressure vessel, and wherein:
- (i) the at least one reinforced pressure vessel is provided further away from a side sill of the motor vehicle than the at least one reinforcement-free pressure vessel, or
- (ii) the at least one reinforced pressure vessel is provided further away from a wheel axis of the motor vehicle than the at least one reinforcement-free pressure vessel,
- wherein a floor plate is provided between the plurality of pressure vessels and a carriageway, and wherein a first region of the floor plate that at least partially covers the reinforced pressure vessel is formed from a different material or from a different layered structure from a second region of the floor plate that at least partially covers the reinforcement-free pressure vessel.
