A self-propelled road milling machine is equipped with a cooling system comprising a fan for drawing in air, a cooler, and a suction channel. The suction channel has a vent opening facing the cooler and an intake opening. In relation to the longitudinal axis of the road milling machine, the intake opening points to the side of the road milling machine, so that air is drawn in from the side. This results in significantly less dirt being sucked into the machine than when the suction channel is positioned in the direction of travel. In a preferred embodiment, the suction channel is formed in one piece with a liquid tank of the road milling machine. The liquid tank and suction system therefore form a modular unit, which can be easily installed on the chassis of the road milling machine.

We claim: 1. A self-propelled road milling machine with a cooling system having at least one fan for drawing in air, at least one cooler, and at least one suction channel, the at least one suction channel has a vent opening facing the at least one cooler and an intake opening, wherein, in relation
We claim: 1. A self-propelled road milling machine with a cooling system having at least one fan for drawing in air, at least one cooler, and at least one suction channel, the at least one suction channel has a vent opening facing the at least one cooler and an intake opening, wherein, in relation to a longitudinal axis of the road milling machine, the intake opening points to a side of the road milling machine so that air can be drawn in from the side, wherein the at least one suction channel has a first channel section directly following the intake opening, through said first channel section air flows essentially parallel to the longitudinal axis, a second channel section connected to the first channel section, and air in this second section flows essentially at right angles to the longitudinal axis, a third channel section connected to the second channel section, and through this third channel section air flows essentially parallel to the longitudinal axis toward the vent opening. 2. The road milling machine according to claim 1, wherein the first, second and third channel sections are positioned in such a way that the air in the first channel section flows essentially counter to a direction of travel of the road milling machine, and the air in the second channel section flows essentially at right angles to the direction of travel, and the air in the third channel section flows counter to the direction of travel. 3. The road milling machine according to claim 1, wherein the at least one suction channel is covered on the side by a removable plate. 4. The road milling machine according to claim 3, wherein the intake opening is constructed in the plate. 5. The road milling machine according to claim 3, wherein the plate is equipped with a sound-absorbing mat. 6. The road milling machine according to claim 1, wherein the first channel section is covered by a removable plate. 7. The road milling machine according to claim 1, wherein the at least one cooler comprises a cooling circuit for a drive unit coolant and a cooling circuit for a hydraulic fluid of a hydraulic system. 8. The road milling machine according to claim 1, wherein the road milling machine comprises a rear-loading road milling machine. 9. A self-propelled road milling machine with a cooling system having at least one fan for drawing in air, at least one cooler, and at least one suction channel, the at least one suction channel has a vent opening facing the at least one cooler and an intake opening, wherein, in relation to a longitudinal axis of the road milling machine, the intake opening points to a side of the road milling machine so that air can be drawn in from the side, wherein said at least one suction channel comprises a first suction channel and a second suction channel, wherein an intake opening of the first suction channel points to one side and an intake opening of the second suction channel points to an opposite side of the road milling machine. 10. A self-propelled road milling machine with a cooling system having at least one fan for drawing in air, at least one cooler, and at least one suction channel, the at least one suction channel has a vent opening facing the at least one cooler and an intake opening, wherein, in relation to a longitudinal axis of the road milling machine, the intake opening points to a side of the road milling machine so that air can be drawn in from the side, wherein the at least one suction channel is constructed inside a liquid tank. 11. The road milling machine according to claim 10, wherein the at least one suction channel is constructed in one piece with the liquid tank. 12. The road milling machine according to claim 10, wherein the liquid tank is made of plastic. 13. The road milling machine according to claim 10, wherein the at least one cooler and the at least one fan are attached to the liquid tank. 14. The road milling machine according to claim 10, wherein the liquid tank is positioned above a steerable wheel or a steerable wheel axis, a channel extends through the liquid tank, the channel carries a means of transmission that allows orientation of the wheel or the wheel axis to be transmitted to a direction indicator on a top side of the liquid tank. 15. The road milling machine according to claim 10, wherein the at least one suction channel is covered on the side by a removable plate. 16. The road milling machine according to claim 15, wherein the intake opening is constructed in the plate. 17. The road milling machine according to claim 15, wherein the plate is equipped with a sound-absorbing mat. 18. The road milling machine according to claim 10, wherein the road milling machine comprises a rear-loading road milling machine.
