Description
PENDULATION DEVICE BASED ON CONNECTING RODS AND FORKLIFT TRUCK Description of the invention The present invention relates to vehicles where the trucks or bogies ensure a pendular compensation of the lateral inclination insufficiency in general and consists more particularly in a pendulum device based on connecting rods and in a forklift truck or bogie. DE 43 43 998 describes the links between the trucks or bogies and the chassis of a railway vehicle. Figure 1 of this prior art document shows a railway vehicle where the truck or bogie ensures a pendular compensation of the lack of lateral inclination by applying a residence angle to a tilt crossbar and then to the vehicle body . This pendular compensation is obtained by means of a pendulum device based on cranks. The pendulum device based on rods of the prior art comprises a tilt crossbar arranged in a bogie chassis and suspended by means of rods. The pendulum movement between the inclination cross member and the bogie chassis is obtained due to the presence of rotating plates or articulations in each of the extremities of the connecting rods. As described in the prior art, the primary suspensions are arranged between the bogie chassis and the bearings, the secondary suspensions are arranged between the tilt cross member and the vehicle body. REF: 26184 In a pendulum device based on cranks as such, of the prior art, the drag forces between the chassis of the bogie or truck and the vehicle body are taken up by the connecting rods. According to the teaching of the state of the art, the anti-corner dampers thus arranged suffer struggles or jerks that are caused by the inclination between the chassis of the bogie and the vehicle body. A drawback of the above is that the anticurve dampers are not constantly arranged parallel to the secondary suspensions to which they are associated. In effect, during the pendulum compensation and then due to obtaining an angle of residence of the box, the struggle or jolt due to the inclination between the vehicle body and the tilt cross makes a horizontal effort appear. A drawback due to this horizontal stress is the appearance of a coupling of the anti-bending coupling forces between the vehicle body and the bogie during the pendulum compensation. Another drawback of the connecting rod-based pendulum device of the prior art is that the force pairs caused by the curve are taken up by the inclining cross member because they are butted against the chassis of the bogie or truck. It results from the above that the rigidity or angular tension between the chassis of the truck and the vehicle box is random. Thus, an object of the invention is a pendulum device based on connecting rods and a pendulum truck or bogie based on rods that do not have the disadvantages of the pendulum devices based on connecting rod and forklift trucks or bogies crank base of the prior art. According to the invention, the pendulum device based on connecting rods for the inclination crossbar, is capable of being arranged in a chassis of the truck, so as to be suspended to the chassis of the truck by means of the rods, the suspensions Secondary sections are arranged between the tilt crossbar and the vehicle body, the connecting rods, the tilt crossbar and the truck chassis form, in the radial plane, a trapezoid of articulated rigid elements from which the minor base joins the crossbar of inclination and the greater base is united to the chassis of the trolley and where the sides are constituted of the cranks, the connecting rods are arranged obliquely in a convergent manner, characterized in that the middle crosspieces of the chassis of the truck, the rods and the tilt crossbar form a set such that the rigidity or angular tension between the chassis of the truck and the vehicle body It is a default feature. According to a feature of the invention, the radial rigidity between the truck chassis and the vehicle body is a predetermined characteristic because each rod comprises at its upper end a superior rest associated with a first element of reception of the upper rest , carried out in a middle crossbar of the chassis of the truck and has at its lower end a lower rest associated with a second element of reception of the lower rest, made in the tilt crosspiece. The pendulum device based on rods, of the invention, also satisfies at least one of the following characteristics: the anti-curves dampers are arranged between the vehicle body and the tilt cross member, parallel to the secondary suspensions to the which are associated, - an intermediate crossbar is arranged between the secondary suspensions of the vehicle body and the inclining crosspiece, in order to support the secondary suspensions, an element of smoothing type is arranged between the intermediate cross member and the inclining cross member , - an actuating element of the pendular compensation of the lateral inclination insufficiencies is attached to the tilting crossbar of the truck chassis. According to the invention, the pendulum truck based on cranks is characterized in that it comprises a pendulum device based on connecting rods according to any of the preceding characteristics. An advantage of the pendulum device based on connecting rods and of the pendulum-based pendulum truck or bogie of the invention, due to the application of the breaks in the extremities of the connecting rods, is that the tension or angular rigidity between the Trolley chassis and vehicle box is a predetermined feature. Another advantage of the pendulum device based on connecting rods and the fork-lift truck or bogie based on connecting rods of the invention is that it is possible to get rid of the play between the tilting cross member and the truck chassis. Another advantage of the pendulum device based on connecting rods and of the pendulum fork-lift truck of the invention, is that it is possible, according to a first embodiment, to arrange the anti-buff cushions between the vehicle body and the crossbar. of inclination. An embodiment as such is possible because, as mentioned hereinabove, the angular tension between the truck chassis and the vehicle body is a predetermined characteristic, in the case of the invention, contrary to the case of the previous technique. In an arrangement as such, the anti-curves shock absorbers do not suffer the struggle or shake linked to the inclination between the chassis of the truck and the vehicle body. The result of this is an absence of stockpiling of the anti-bending coupling efforts between the vehicle body and the truck during the pendulum compensation. Another advantage of the pendulum device based on connecting rods and of the fork-lift truck or bogie of the invention is that it is possible, according to another embodiment, to arrange straighteners between the vehicle body and the tilt cross member . An embodiment as such is also possible because, as mentioned hereinabove, the angular tension between the truck chassis and the vehicle body is a predetermined characteristic, in the case of the invention.
