Abstract

The invention relates to a commercial vehicle (1) comprising a tractor unit (2) for a semi-trailer (3), wherein the tractor unit (2) is configured for operation with cryogenic hydrogen, wherein the tractor unit (2) has a chassis (4) on which a cabin (5) is arranged, behind which a technical tower (6) is arranged on the chassis (4), wherein at least one hydrogen converter (7) and / or a boil-off management system (7) and / or an intermediate storage tank (7) for boil-off / blow-off gas is arranged in the technical tower (6).

Description

[0001] The invention relates to a commercial vehicle according to the preamble of claim 1.

[0002] WO 2021 / 256923 A1 describes a truck or tractor-semi-trailer combination connected via a fifth wheel coupling, comprising a cabin and an air plenum, wherein the air plenum is provided between a rear end of the cabin and the semi-trailer and has a front wall substantially adjacent to or identical to a cabin rear wall, and a rear wall spaced from the front wall and substantially coplanar, wherein the air plenum is provided with an air access structure and a heat exchanger, wherein the air access structure provides air access to the air plenum and the heat exchanger, wherein the heat exchanger is provided in the rear wall of the air plenum and extends at least partially across the width of the truck, and wherein the air access structure comprises lateral air access openings,which are provided on the side walls of the air collection chamber and are designed to provide at least a passive air flow from the air inlet side connections to the heat exchanger.,

[0003] The invention is based on the object of providing a novel commercial vehicle.

[0004] The object is achieved according to the invention by a commercial vehicle having the features of claim 1.

[0005] Advantageous embodiments of the invention are the subject of the subclaims.

[0006] A commercial vehicle is proposed which is configured for operation with cryogenic hydrogen, wherein the commercial vehicle has a chassis on which a cabin is arranged, behind which a technology tower is arranged on the chassis.

[0007] According to the invention, at least one hydrogen converter and / or a boil-off management system and / or an intermediate storage facility for boil-off / blow-off gas is arranged in the technical tower.

[0008] The hydrogen converter and / or the boil-off management system and / or the intermediate storage system are thus safely arranged and protected from external influences such as rockfall, spray or road salt.

[0009] The hydrogen converter and / or buffer storage unit is thus located outside the driver's work area. Its position remains unchanged regardless of the cabin tilt, as the technology tower remains fixed in position when the cabin is tilted.

[0010] By arranging the hydrogen converter in the technical tower, it is located outside of a wading zone, thus improving wading capability and reducing the risk of the hydrogen converter being flooded with water.

[0011] In addition, the exhaust air from the hydrogen converter is discharged at a comparatively high altitude, i.e. at a great distance from the ground.

[0012] Embodiments of the invention are explained in more detail below with reference to a drawing.

[0013] It shows: Fig. 1 a schematic view of a vehicle.

[0014] The only Fig. Figure 1 is a schematic view of a vehicle 1, in particular a commercial vehicle 1, for example, a commercial vehicle combination 1, comprising a tractor 2 and a semitrailer 3 coupled thereto. In other embodiments, a trailer can also be coupled to the tractor 2. Likewise, the tractor 2 can be operated solo. For example, the tractor 2 can also have a flatbed, a tipping body, a concrete mixer, or another body.

[0015] The vehicle 1 is configured in particular for operation with a cryogenic fuel, for example hydrogen or liquefied methane.

[0016] The tractor 2 has a chassis 4 on which a cabin 5 (driver's cab) is arranged. Behind the cabin 5, i.e., opposite a direction of travel F, a technical tower 6 is arranged on the chassis 4.

[0017] At least one hydrogen converter 7 and / or a boil-off management system 7 and / or an intermediate storage unit 7 for boil-off / blow-off gas is arranged in the technical tower 6.

[0018] This at least one component is thus securely positioned and protected from external influences such as rockfall, spray or road salt.

[0019] The hydrogen converter 7 can be designed as a catalyst.

[0020] The hydrogen converter 7 and / or the buffer storage 7 are thus located outside the driver's working area. Their position therefore remains independent of the tilting of the cabin 5, since the technology tower 6 remains fixed in its position when the cabin 5 is tilted.

[0021] By arranging the hydrogen converter 7 in the technical tower, it is located outside a wading zone, thus improving the wading capability and reducing the risk of the hydrogen converter 7 being flooded with water.

[0022] In addition, the exhaust air from hydrogen converter 7 is discharged at a comparatively high height, i.e. at a great distance from the ground.
