Problems solved by technology
In particular, when the cooling device of the main transformer is arranged integrally in the underbody region of the hybrid vehicle, the cooling device will be adversely affected
[0007] A secondary (diesel-based) combustion drive will be endangered if the ventilation provided for the cooling of the main transformer freezes on the surface of the cooling and therefore cannot draw air in sufficiently for the required cooling Transition to antenna-based electric drives
As a result, the cooling water used for cooling would be so heated that the antenna-based drives would be endangered

Embodiment Construction
[0043] The hybrid vehicle 1 as a rail vehicle has two different drives, namely: on the one hand a combustion-based drive or internal combustion engine 100 and an electric antenna-based drive 200 .
[0044] In this case, internal combustion engine 100 is designed, for example, as a diesel engine with cylinders 101 for burning (diesel) fuel. Sixteen cylinders 101 are shown here by way of example, which are arranged in two rows with eight cylinders 101 each.
[0045] Internal combustion engine 100 has a cooling circuit, which is referred to below as first cooling circuit KK1 . The cooling circuit is provided to conduct heat generated by internal combustion engine 100 by means of heat transfer medium 102 to cooler 106 , which dissipates the heat supplied to it to the environment of internal combustion engine 100 or hybrid vehicle 1 .
[0046] The first cooling circuit KK1 thus has a cylinder 101 , a heat transfer medium 102 , a collection container 103 , a distribution container 10...

The invention relates to a hybrid vehicle, in particular a hybrid rail vehicle, having an internal combustion engine and an additional electric drive. The internal combustion engine (100) has a first cooling circuit (KK1) with a heat transfer medium (102) and a cooler (106). The first cooling circuit (KK1) is designed to absorb heat of the internal combustion engine (100) by means of a heat transfer medium (102) and to conduct it to the cooler (106). The electric drive (200) has a second cooling circuit (KK2) with a heat transfer medium (202) and a cooler (206), the second cooling circuit (KK2) being provided for conducting heat of a component (201) of the electric drive (200) to the cooler (206) by means of the heat transfer medium (202). A preheating circuit (VWK) is arranged between the first cooling circuit (KK1) and the second cooling circuit (KK2) and is connected to the first cooling circuit (KK1) via two connection points (VP1, VP2). The preheating circuit (VWK) and the second cooling circuit (KK2) are thermally coupled by means of a thermal coupling (208) as a common component in such a way that heat can be exchanged in a controllable manner between the heat transfer media (102, 202) of the two cooling circuits (KK1, KK2). The preheating circuit (VWK) has an electric heater (406) which is connected in series to the thermal coupling (208) such that the heat transfer medium (102) of the first cooling circuit (KK1) likewise flows through the electric heater (406). The electric heater (406) is arranged and constructed in such a way that heat generated by the electric heater can be transferred in at least one of the two cooling circuits (KK1, KK2) when needed.
Description
technical field [0001] The invention relates to a hybrid vehicle, in particular a hybrid rail vehicle, which has an internal combustion engine and an additional electric drive. Background technique [0002] In this case, in particular a diesel engine is considered as an internal combustion engine, while in particular a conventional electric drive of a rail vehicle is provided as an electric drive with the (main) components required for this, to which the electric drive is connected via contact wires. The drive supplies electrical power. [0003] It is known that the internal combustion engine cannot be started at every temperature from certain structural dimensions, so that at extreme temperatures the internal combustion engine must be preheated for this purpose. [0004] The application with file number DE 10 2018 207 852.1 describes the heating of a diesel engine of a hybrid vehicle. In this case, a thermal change from components of the antenna-based electric drive to co...
