Problems solved by technology

[0009] Document WO / 2008 / 139440 proposes an aircraft tug that can perform the taxiing phase by allowing the pilot to check the direction and speed of the tug, however, such an aircraft tug includes a complex gripping system; many actuations are necessary The machine installs the nose landing gear of the aircraft on the tractor
Therefore, the loading / unloading steps of the aircraft are all too long and complicated
In addition, the large number of actuators makes unloading the aircraft difficult and time-consuming in the event of a failure of the tractor

Embodiment Construction

[0073] An aircraft tractor is proposed which has a gripping system for gripping the nose landing gear of an aircraft. The tractor consists of a chassis and wheel modules connected to the chassis. Each wheel module includes at least one actuator for guiding the vertical movement of the module relative to the chassis. In this way it is possible to raise or lower the chassis relative to the drive panel. The tractor also includes a grabbing platform for grabbing the nose gear of the aircraft, which together with the chassis has degrees of freedom (essentially circular translation, i.e. all points of the platform have trajectories of circles with the same radius but different centers ). In this way, the platform maintains a substantially fixed angle relative to the chassis of the tractor due to the degree of freedom of the platform's substantially circular translation relative to the chassis. In this way, the handling platform can be moved in a rocking motion relative to the cha...

Abstract

The invention relates to a plane tractor (1) which grips the nose gear of a plane, including: a chassis (5); wheel modules (3) connected to the chassis, each wheel module including at least one actuator for inducing a vertical movement of the module in relation to the chassis; a gripping platform (2) for gripping the nose gear of a plane (4), the platform together with the chassis having freedom of movement substantially in circular translation; and an actuating means connecting the platform and the chassis.

Description

technical field [0001] The present invention relates to an aircraft tractor used to tow an aircraft in an airport, more particularly, to an aircraft tractor comprising a grabbing device, a grabbing device for grabbing the nose landing gear of an aircraft using such a tractor method and a method for pulling a plane. Background technique [0002] The tractors currently in use are equipped with a grabbing device that lifts the aircraft's nose landing gear, thereby towing the aircraft, which, as far as we know, consists of a pair of wheels, each containing a tire, which A pair of wheels is secured at the end of a strut pointing down from the nose of the aircraft. [0003] A known grab system for a tractor comprises an articulated trailing arm extending at the inlet of the grab system and intended to be placed on the rear of the nose gear of the aircraft. This trailing arm is close to the wheel to buckle the nose gear. Opposite the trailing arm, a scoop-shaped slat is fixed la...
