The trailer includes an articulated drawbar mounted on the axle, the articulated drawbar being mounted so that it is free and sliding with respect to the chassis; and an actuator sliding the articulated drawbar. The articulated drawbar is V-shaped, a first end is fixed to a hitch tongue, a second end is fixed to the axle near a first wheel, and a third end is fixed to the axle near a second wheel. ## Claims ### Claim 1 A tilting trailer comprising: a chassis mounted on an axle that pivots with respect to first and second wheels of said trailer; an articulated drawbar mounted on said axle, said articulated drawbar being mounted so that it is free and sliding with respect to said chassis; and an actuator, which actuates sliding of said articulated drawbar, wherein said articulated drawbar is V-shaped, a first end being fixed to a hitch tongue, a second end being fixed to said axle via a first articulated part in a vicinity of the first wheel, and a third end being fixed to said axle via a second articulated part in a vicinity of the second wheel, and wherein said trailer is movable between a top position, also called road position, in which the chassis and the drawbar are substantially parallel to ground, and a bottom position also called loading position, in which the chassis is inclined with respect to the ground. ### Claim 2 (depends on 1) The trailer according to claim 1, wherein said actuator comprises a control lever and a cylinder belonging to the group consisting of: a hydraulic cylinder; a pneumatic cylinder; an electric cylinder; a mechanical cylinder. ### Claim 3 (depends on 1) The trailer according to claim 1, wherein said actuator is mounted in a vicinity of a hitch tongue mounted on said articulated drawbar. ### Claim 4 (depends on 1) The trailer according to claim 1, wherein said actuator is integral with said chassis and with said articulated drawbar. ### Claim 5 (depends on 1) The trailer according to claim 1, wherein the trailer comprises a guide, which guides a movement of said articulated drawbar during a sliding of said articulated drawbar with respect to said chassis. ### Claim 6 (depends on 5) The trailer according to claim 5, wherein said guide comprises rails or rolling elements. ### Claim 7 (depends on 1) The trailer according to claim 1, wherein the trailer comprises a lock, which locks a position of said articulated drawbar. ### Claim 8 (depends on 7) The trailer according to claim 7, wherein said lock includes a pin or a rivet. ### Claim 9 (depends on 1) The trailer according to claim 1, wherein the trailer comprises a number plate fixed to said chassis, and a retracting device for retracting said number plate making it possible to retract said plate during the tilting of said chassis. ### Claim 10 (depends on 9) The trailer according to claim 9, wherein said retracting device is automatically activated during the activation of the actuator. ### Claim 11 (depends on 1) The trailer according to claim 1, wherein a first portion of said actuator is mounted on said articulated drawbar and a second portion of said actuator is mounted on said axle. ### Claim 12 (depends on 11) The trailer according to claim 11, wherein said first portion of said actuator comprises a pump, and said second portion of said actuator comprises a cylinder connected to said pump. ### Claim 13 (depends on 1) The trailer according to claim 1, wherein the trailer comprises a suspension located inside said axle. ### Claim 14 A tilting trailer comprising: a chassis mounted on an axle that pivots with respect to first and second wheels of said trailer; an articulated drawbar mounted on said axle, said articulated drawbar being mounted so that it is free and sliding with respect to said chassis, wherein said articulated drawbar is V-shaped, a first end being fixed to a hitch tongue, a second end being fixed to said axle in a vicinity of the first wheel, and a third end being fixed to said axle in a vicinity of the second wheel; an actuator, which actuates sliding of said articulated drawbar; a number plate fixed to said chassis; and a retracting device for retracting said number plate making it possible to retract said plate during the tilting of said chassis.
