Problems solved by technology

[0012] The disadvantages of the gas tank systems that have been used in practice until now, as shown by way of example at the outset, lie in particular in the fact that, for the fastening of the gas tank to the vehicle and for the necessary valve protection structures, such as crash fenders, requiring a considerable number of components, which causes a relatively high time consumption during assembly and is associated with high component and manufacturing costs

Embodiment Construction

[0038] Thus, a preferred embodiment of the gas tank fastening device according to the invention for a vehicle that can be powered by gaseous fuel comprises a cylindrical gas tank, indicated overall by the reference numeral 1 and shown here only partially. The gas tank 1 is provided with a hole for accommodating a gas valve for controlling the inflow and outflow of gaseous fuel in the gas tank. The gas valve is designed as an internal valve, wherein the valve body has a control device for controlling the gas valve, and other components, such as a manual shut-off valve and various safety devices, and most of the valve body is installed in the inner cavity of the gas container 1 .

[0039] The valve body is provided for this purpose with an external thread which is screwed into an opening provided with an internal thread of the gas tank 1 . exist figure 1 Only the end 7 ("valve body head") of the valve body of the gas valve protruding from the gas tank 1 can be seen in the figur...

Abstract

A fastening arrangement for a gas tank (1) of a motor vehicle comprises: at least one gas tank for storing gaseous fuel; a valve, which is arranged on a section of the gas tank (1) which is provided with an opening, for filling and emptying the gas tank with gaseous fuel, which valve comprises a valve body (7) having control elements for controlling the valve function and connecting pieces for connecting to gaseous fuel lines; and a protective element, which is arranged on that side of the valve body (7) which faces away from the gas tank and at least partially covers the valve body (7), for protecting the valve body (7) from a mechanical introduction of force; a bracket for fastening the gas tank (1) to the vehicle and comprising a vehicle fastening section which is fastened on the vehicle and a tank fastening section which is fastened on the gas tank, wherein the support element serves as a tank fastening section for fastening the gas tank to the vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and relates to a fixing device for a gas storage tank of a vehicle driven by gaseous fuel. Background technique [0002] In the context of decreasing oil reserves and increasing requirements for exhaust emissions, modern vehicles are increasingly equipped with internal combustion engines that work on the four-stroke principle. Gas fuel powered. [0003] Primarily used are petroleum-based liquefied gases stored in liquid form in tanks, such as vehicle gas (LPG = liquefied petroleum gas), and gaseous fuels stored in gaseous form in tanks, such as natural gas (CNG = compressed natural gas) as gaseous fuel. Vehicle gas consists essentially of propane and butane and occurs as a by-product in the hydrogenation process in petroleum refining, in contrast to natural gas, which consists mainly of methane and is obtained by exploiting natural gas sources. Toxic emissions CO, HC, NO, because gaseous fuel...
