  • the belt 212 moves and transfers the rotation to the driven gear 210 and, consequently, to the interaction element 204.
  • the driving gear 208 comprises a smaller diameter than the diameter of the driven gear 210.
  • the transmission system 206 increases the torque transferred from the motor 202 to the interaction element 204, reducing the necessary power of the motor 202 to move the cover 130 and facilitating the movement thereof.
  • the interaction element 204 is the component responsible for receiving the rotation derived from the motor 202 and transmitting to a component of wagon 100 aiming at moving the cover 130 in relation to the wagon 100.
  • the interaction element 204 is a gear configured to interact with a rack 150 that is longitudinally present in wagon 100.
  • the rotation of motor 202 moves the transmission system 206, which turns the gear.
  • the turning of the gear which interacts with the rack 150 moves the cover 130 along the longitudinal axis of the wagon 100.
  • the cover movement system 200 further comprises an uncoupling device 220.
  • the uncoupling device 220 is a component of the system which allows the coupling and uncoupling between the transmission system 206 and the interaction element 204.
  • the cover movement system 200 of the present disclosure enables the change between an automatic movement of the cover 130, when the uncoupling device 220 is in the coupled mode, and manual, when the uncoupling device 220 is the uncoupled mode.
  • Said possibility is particularly advantageous in an automatic system, since the motor 202 when stopped blocks or makes difficult the movement of the cover 130 in a manual manner, limiting the use of the systems which do not allow the uncoupling between the cover movement system 200 and the cover 130.
  • the uncoupling device 220 illustrated in detail in Figures 5 and 6 , comprises an extension sleeve 222 which performs the coupling between the shaft of motor 202 and the shaft of the transmission system 206 - in this case, the driven gear 210.
  • the movement of the extension sleeve 222 is carried out by a key 224 which fits into an orifice present in the uncoupling device 220.
  • the key 224 can be, for example, a key 224 already used in wagon 100 for other systems (for example, for activating the electric system), thus reducing the complexity and number of components of wagon 100.
  • the extension sleeve 222 positions itself so as to interact both with the shaft 228 of the driven gear 210 as with the shaft 226 of the interaction element 204, thus performing the transmission of the rotation from one shaft to the other.
  • the extension sleeve 222 positions itself so as to interact only with the shaft 228 of the driven gear 210 but does not interact with the shaft 226 of the interaction element 204, uncoupling the shaft 226 of the interaction element 204 of the cover movement system 200.
  • the cover movement system 200 may not comprise the transmission system 206.
  • the motor 202 associates directly with the interaction element 204 and the uncoupling device 220 promotes the coupling/uncoupling between the shaft of the motor 202 and the shaft 226 of the interaction element 204.
  • FIGS 7 and 8 illustrate an embodiment of the locking system of the cover 300 of the present embodiment in the locked and unlocked positions.
  • the locking system of the cover 300 comprises at least one locking element 302, at least one locking shaft 304 and an automatic driver 306.
  • the locking system of the cover 300 comprises four locking elements 302, two locking shafts, an automatic driver 306, a connecting element 308 and a manual driver 314.
  • the locking element 302 is the component responsible for associating with a locking handle 142 of the cover 130 or of the cover module 140. In this manner, by interacting with the locking handle 142, the locking element 302 prevents the opening of the cover 130 of the wagon 100.
  • the locking element 302 comprises a hook shape. In this case, when the hook interacts with the locking handle 142 the movement of cover 130 is mechanically prevented from being carried out.
  • a hook shape is shown, other shapes can be used to obtain the same technical effect.
  • the locking element 302 is arranged at the end of the locking shaft 304, or further, the locking elements 302 are arranged at each of the ends of the locking shafts. Thus, from the rotation of the locking shafts, the locking elements 302 move to lock or unlock the cover 130.
  • the locking shafts are configured to transmit the movement of the automatic driver 306 to the locking elements 302.
  • at least one of the locking shafts comprises a shaft gear 312 which interacts with a component of the automatic driver 306, as will be described ahead.
  • the connecting element 308 is a pin connected to the sleeve extensions, configured to transform the linear movement of the pin into a circular movement of the locking shafts.
  • the automatic driver 306 is the component responsible for moving the system. Upon being activated, the automatic driver 306 moves the locking shafts and, consequently, the locking elements 302 to lock or unlock the cover 130 of the wagon 100.
  • the automatic driver 306 of the illustrated embodiment is a pneumatic driver. However, other types of drivers can be used, such as a hydraulic driver or step motor.
  • the automatic driver 306 comprises a rack 310, or similar element, configured to interact with the locking shaft 304 by means of the shaft gear 312. The interaction of the rack 310 of the automatic driver 306 with the shaft gear 312 transforms the linear movement of the automatic driver 306 into shaft rotation. Consequently, the driving of the automatic driver 306 promotes the movement of the locking elements 302 and, in this way, the locking or unlocking of the cover 130 of the wagon 100.
  • the cover locking system 300 further comprises the manual driver 314.
  • the manual driver 314 is the component of the system which allows the locking or unlocking of the cover 130 to be made in a manual way.
  • the locking system of the cover 300 of the present invention reaches the advantageous technical effect of enabling the locking or unlocking of the cover 130 to be performed in an automatic way through the automatic driver 306, or in a manual way, through the manual driver 314.
  • the manual driver 314 shown is a clasp comprised at the ends of the locking shafts.
  • the clasp is configured to be manually handled by an operator and enables the movement of the system in an independent manner from the automatic driver 306.
  • the use of the system of the present invention is not limited to automatic means.
  • FIGS 9, 10 and 11 illustrate different views of the wagon 100 of the present embodiment to facilitate visualizing some of the characteristics and the general understanding of the wagon 100 comprising the systems described.
  • wagon 100 of the present disclosure further comprises a logic driver which controls the cover movement system 200 and the cover locking system 300 in an integrated manner.
  • the logic driver is a component responsible for driving motor 202 of the cover movement system 200 and the automatic driver 306 of the cover locking system 300 at specific moments according to a predefined operational sequence. Said operational sequence can be defined according to the needs of each project and the need for use, making it possible to define one or more sequences of interest.
  • the logic driver comprises the following steps for the closing of cover 130 of wagon 100: driving the motor 202 of the cover movement system 200 until the cover module 140 interacts with the bulkhead 120 of wagon 100; and driving the automatic driver 306 of the cover locking system 300 until the interaction between the locking element 302 and the locking handle 142 locks the movement of the cover module 142 in relation to wagon 100.
  • the logic driver comprises the following steps for the opening of cover 130 of wagon 100; driving the automatic driver 306 of the cover locking system 300 until there is no interaction between the locking element 302 and the locking handle 142 for unlocking the cover module 140; driving the motor 202 of the cover movement system 200 in the direction of the opening of cover 130 until the desired position is reached in the cover module140.
  • the present disclosure describes a movement system for wagon cover 200 that comprises a motor 202 associated with an interaction element 204 configured to interact with a wagon 100 and move a cover 130. It further refers to a wagon cover locking system 300 that comprises at least one shaft 304 and at least one locking element 302 associated with the shaft 304 and configured to fit within a wagon 100 cover 130.
