Abstract: A high-temperature battery for a vehicle with an electric drive and that supplies the electric drive with power has a thermally insulating housing in order to avoid thermal losses. The battery also has a cooling system that limits the operating temperature during the charging and during the power drain. The dissipated heat of the cooling system is used to heat the vehicle. There is provision for the vehicle to be preheated during the charging of the battery so that during the driving mode the temperature to which the passenger compartment has been heated merely has to be maintained. Thus, even when the overall amounts of dissipated heat from the cooling system are low, heating to a comfortable degree is possible.

Abstract: The invention relates to an omnibus track guidable vehicle for special roads which vehicle can also travel with free manual steering on normal roads. To make the trailing axle roll along the special road, which defines the track, with correct tracking and without contact, the trailing vehicle axle is provided with an elastokinematic self-steering system. Articulation of the axle body of this vehicle axle in the transverse direction is in fact made so that the axle body is transversely slidable out of the central position by approximately .+-.0.8 to 1.2% of the vehicle width with increasing force, limited as a function of the transverse force.
