Abstract
The invention relates to a towing vehicle (100) for maneuvering aeroplanes without using tow bars, comprising a braking device (130) having a first fluidically actuable braking circuit (148) which acts on the front wheels (106) and a second fluidically actuable braking circuit (150) which acts on the rear wheels (110). According to the invention, the braking device (130) further comprises a third fluidically actuable braking circuit (152), which likewise acts on the front wheels (106).
Claims12
A towing vehicle for maneuvering an aircraft without using tow bars, comprising:
- a chassis;
- at least one front axle having at least two front wheels;
- at least one rear axle having at least two rear wheels;
- a braking device having a first fluidically actuable braking circuit which acts on the front wheels and a second fluidically actuable braking circuit which acts on the rear wheels;
- and
- a third fluidically actuable braking circuit which acts on the front wheels,
- wherein the braking device comprises a control unit which is configured to control (i) the second fluidically actuable braking circuit when a weight of the aircraft exceeds a predetermined value, and (ii) when the weight of the aircraft does not exceed the predetermined value, to control only the first fluidically actuable braking circuit and the third fluidically actuable braking circuit, such that the towing vehicle is braked exclusively by means of the front wheels of the front axle.
A towing vehicle for maneuvering an aircraft without using tow bars, comprising:
- a substantially U-shaped chassis comprising a coupling device for gripping and lifting a nose wheel of an aircraft;
- at least one front axle having at least two front wheels;
- two front wheel braking units assigned to at least one of the front wheels;
- at least one rear axle having at least two rear wheels;
- a rear wheel braking unit assigned to at least one of the rear wheel;
- a braking device comprising:
- a first fluidically actuable braking circuit configured to act on the front wheels, wherein the first fluidically actuable braking circuit comprises a front braking unit of the two front wheel braking units,
- a second fluidically actuable braking circuit configured to act on the rear wheels wherein the second fluidically actuable braking circuit comprises the rear wheel braking unit,
- a third fluidically actuable braking circuit configured to act on the front wheels, wherein the third fluidically actuable braking circuit comprises an additional front braking unit of the two front wheel braking units;
- and
- a control unit configured to (i) control the second fluidically actuable braking circuit to brake the aircraft via the rear wheel braking unit when a weight of the aircraft exceeds a predetermined value, and (ii) control only the first fluidically actuable braking circuit and the third fluidically actuable braking circuit to brake the aircraft via the front wheel braking units when the weight of the aircraft does not exceed the predetermined value.
