Description

[0001] MATERIAL TRANSPORT VEHICLE AND ENGINE ASSEMBLY FOR SUCH A VEHICLE

[0002] Field of invention

[0003] The invention relates to the field of vehicles comprising a container for loading, transporting and unloading materials. More particularly, the invention relates to such a vehicle comprising means for unloading said materials without having to move the container.

[0004] State of the art

[0005] For example, tipper vehicles are known for transporting materials. However, these vehicles are unsuitable when unloading areas are cramped and do not allow tipping (tipping the skip), such as in a tunnel or a building. Furthermore, tipping presents numerous safety problems, including the risk of the vehicle tipping over, for example when it is on uneven ground and / or in high winds.

[0006] To overcome these drawbacks, vehicles have been designed in which the container intended to contain the materials has a movable partition which can be moved by force back and forth inside the container in order to unload the materials through a rear door of the container without having to tip the container.

[0007] Such a vehicle is known from US patent US4078682. The container of this vehicle has a movable transverse partition which can be moved by means of a set of traction cables connected via a set of pulleys to a motor. The cables and the motor of this vehicle are, however, only designed to move the partition in one direction.

[0008] Swiss patent CH446182 describes a garbage truck with a tilting container. The container has a movable partition that is pulled backward by means of a pair of endless chains powered by a hydraulic motor. In order to be able to move the partition in both directions (front to back and back to front), the motor must be able to rotate in both directions, which is not always possible with a hydraulic motor. Summary of the invention

[0009] One object of the invention is to provide a vehicle provided with a container having a movable partition which can be pulled forward and backward of the container, particularly when the force to be applied to the movable partition must be much greater when it is pulled backward to unload materials contained in the container, than when the movable partition is pulled forward to return it to its initial position.

[0010] The invention is defined by the independent claims. The dependent claims define preferred embodiments of the invention.

[0011] According to the invention, a vehicle is provided comprising a container for loading, transporting and unloading materials, said container extending longitudinally along a front-rear axis of the vehicle and comprising a left side wall and a right side wall, an opening rear wall for unloading said materials, and a movable partition extending transversely inside the container.

[0012] The vehicle also includes:

[0013] - a first flexible mechanical connection, a front part of which is connected to a left side of the partition and which extends first towards the rear of the vehicle, then upwards or downwards via at least a first pulley,

[0014] - a second flexible mechanical connection, a front part of which is connected to a right side of the partition and which extends first towards the rear of the vehicle, then upwards or downwards via at least one second pulley,

[0015] - at least one third flexible mechanical connection, a front part of which is connected to the partition and which extends first towards the front of the vehicle, then upwards or downwards via at least one third pulley,

[0016] - a first traction assembly comprising a first motor and a first transmission, the first transmission having a first input connected to the first motor and a first output provided with a first winding means to which a left end of the first flexible mechanical connection is fixed and a second output provided with a second winding means to which a right end of the second flexible mechanical connection is fixed, the first transmission comprising at least one speed reducer for reducing the speed between the first input on the one hand and the first and second outputs on the other hand,

[0017] - a second traction assembly comprising a second motor and a second transmission, the second transmission having a second input connected to the second motor and a second output provided with a third winding means to which one end of the third flexible mechanical connection is fixed, the second transmission preferably comprising a speed reducer between the second motor (M2) and the third winding means (E3),

[0018] - means for controlling the first traction assembly and the second traction assembly, the control means comprising a control unit.

[0019] Having two different traction assemblies, each with a different function, allows the movable wall to be moved in both directions, while providing more flexibility in vehicle design and enabling better optimization, particularly in the choice and sizing of motors. The second motor may, for example, have a lower power than the first motor. The second motor may, for example, be a hydraulic motor and the first motor may, for example, be an electric motor.

[0020] The vehicle container is a container designed for loading, transporting and unloading solid and / or liquid materials. The container may be a skip, a container, a tank, etc. In the case of a container designed for transporting and unloading solid materials, said container is preferably a box that is open or can be opened on at least one upper part.

[0021] Preferably, the vehicle comprises means for reducing a resistive torque of the first traction assembly when and while the second traction assembly is being operated. This makes it possible to reduce the power required for the second motor, and therefore to limit its weight and / or its cost.

[0022] Preferably, the vehicle comprises means for reducing a resistive torque of the second traction assembly when and while the first traction assembly is in operation. This makes it possible to reduce the power required for the first engine, and therefore to limit its weight and / or its cost. Said means for reducing the resistive torque of the first and / or the second traction assembly may be of different natures, examples of which will be provided below.

[0023] The invention also relates to a module or kit comprising the first traction assembly and the second traction assembly as well as optionally a control unit, said module or kit being able to be mounted on a vehicle whose container is provided with the movable partition as well as flexible mechanical connections.

[0036] Detailed description of embodiments of the invention

[0037] Fig. 1 shows a perspective view of an exemplary vehicle according to the invention. The vehicle may be a truck, a semi-trailer, a wagon, a tanker truck, etc.

[0038] The vehicle comprises a container (1) for loading, transporting and unloading solid or liquid materials, preferably for solid materials. The container may be a skip, a container, a tank, etc. In the case of a container designed for loading, transporting and unloading solid materials, said container is preferably an open or openable box on at least one upper part of the container.

[0039] The container (1) extends longitudinally along a front-rear axis of the vehicle and has a length of, for example, between 4000 mm and 15000 mm, and a width of, for example, between 2000 mm and 3000 mm. The container (1) has a left side wall (4a), a right side wall (4b), an opening rear wall (8) (for example a tilting door) for unloading the materials.

[0040] The container (1) also comprises a movable partition (10) extending transversely inside the container (1). This partition may for example be a simple metal plate, flat or curved and optionally provided with buttresses. The container (1) or the vehicle also comprises flexible mechanical connections (14a, 14b, 14c, 14d, 14e) connected to the movable partition as well as two traction assemblies (MT1, MT2), the arrangements and functions of which will be detailed below.

[0041] The container (1) is preferably open or openable from the top so that materials can be loaded from the top. The container (1) may, for example, be completely open from the top or have a door or a tarpaulin or any other equivalent means allowing access to its interior volume from the top.

[0042] Although Fig. 1 shows a container having a front wall which is opposite the rear face (8), this front wall is not essential since the movable partition (10) can act as a front wall. Preferably the container does not have a front wall and in this case it optionally has crosspieces connecting the front ends of the left (4a) and right (4b) side walls and serving as reinforcements.

[0043] Fig. 2 is a schematic cross-sectional view of the vehicle container of Fig. 1.

[0044] Fig. 3 is a longitudinal sectional view of the container of the vehicle of Fig. 1, according to a first exemplary embodiment. For reasons of clarity, the vehicle is no longer shown in this figure as well as the following ones, but it is obviously present.

[0045] We see that the container (1) or the vehicle also includes:

[0046] - a first flexible mechanical connection (14a) a front part of which is connected to a left side of the movable partition (10) and which extends first towards the rear of the vehicle, then upwards or downwards via at least one first pulley (15a), - a second flexible mechanical connection (14b) a front part of which is connected to a right side of the partition (10) and which extends first towards the rear of the vehicle, then upwards or downwards via at least one second pulley (15b),

[0047] - a third flexible mechanical connection (14c) of which a front part is connected to the partition (10) and which extends first towards the front of the vehicle, then upwards or downwards via at least a third pulley (15c),

[0048] - a first traction assembly (MT1) comprising a first motor (M1) and a first transmission (T1), the first transmission having a first input connected to the first motor and a first output provided with a first winding means (E1) to which a rear end of the first flexible mechanical connection (14a) is fixed and a second output provided with a second winding means (E2) to which a rear end of the second flexible mechanical connection (14b) is fixed, the first transmission comprising at least one speed reducer (R1, R2) for reducing the speed between the first input on the one hand and the first and second outputs on the other hand,

[0049] - a second traction assembly (MT2) comprising a second motor (M2) and a second transmission (T2), the second transmission having a second input connected to the second motor as well as a second output provided with a third winding means (E3) to which a rear end of the third flexible mechanical connection (14c) is fixed, the second transmission preferably comprising a speed reducer (R3).

[0050] The vehicle also comprises means for controlling the first traction assembly and the second traction assembly, the control means comprising a control unit (not shown).

[0051] The control means comprise, for example, a three-position switch, for example a “discharge” position, a “neutral” position, and a “bulkhead return” position.

[0052] When the control unit detects that the switch is in the "discharge" position, it will actuate the first traction assembly (MT1) to pull the movable partition towards the rear of the container, and it may, in the case of certain examples described below, actuate the means for reducing a resistive torque of the second traction assembly (MT2). ​​First limit-of-travel means may also be provided for safety purposes in order to stop the first traction assembly (MT1) and interrupt the travel of the movable partition when it reaches the rear of the container.

[0053] When the control unit detects that the switch is in the “partition return” position, it will actuate the second traction assembly (MT2) to pull the movable partition towards the front of the container, and it may, in the case of certain examples described below, actuate the means for reducing a resistive torque of the first traction assembly (MT1). Second limit switch means may also be provided for safety purposes in order to stop the second traction assembly (MT2) and interrupt the travel of the movable partition when it reaches the front of the container.

[0054] And when the control unit detects that the switch is in the “neutral” position, it will stop the first traction assembly (MT1) and the second traction assembly (MT2).

[0055] An emergency stop button may also be provided to stop any movement of the movable partition. The emergency stop button and the three-position switch should preferably be arranged in a location easily accessible to the vehicle driver.

[0056] In the example of Fig. 3, the first traction assembly (MT1) is mounted at the rear of the vehicle, while the second traction assembly (MT2) is mounted at the front of the vehicle.

[0057] Fig. 4 is a longitudinal sectional view of the container, according to a second exemplary embodiment. This example is similar to that of Fig. 3, except that here the first traction assembly (MT1) and the second traction assembly (MT2) are both mounted at the front of the vehicle. In this example, two additional pulleys (15d, 15e) will be provided to bring the first and second flexible mechanical connection (14a, 14b) back to the front of the vehicle. In other examples (not shown), the first traction assembly (MT1) and the second traction assembly (MT2) are both mounted at the rear of the vehicle. In these, an additional pulley will be provided to bring the at least one third flexible mechanical connection (14c) back to the rear of the vehicle.

[0058] According to certain examples, the vehicle according to the invention comprises means for reducing a resistive torque of the first traction assembly (MT1) when and while the second traction assembly (MT2) is put into operation. This makes it possible to use a second engine (M2) of lower power than in the absence of such means and therefore to reduce the cost and / or the price and / or the size thereof.

[0059] The following figures show in more detail the two traction assemblies (MT1, MT2), according to several exemplary embodiments comprising such means for reducing a resistive torque of the first traction assembly.

[0060] Fig. 5 schematically shows a first traction assembly and a second traction assembly of the movable partition (10) according to an example of a vehicle according to the invention. According to this example, the first traction assembly (MT1) comprises a clutch (B) mounted between the first engine (M1) and the first transmission (T1).

[0061] Preferably, the clutch (B) is a controllable clutch, and the control unit (not shown) is configured to engage the clutch (B) when and while the first traction assembly (MT1) is actuated and to disengage the clutch (B) when and while the second traction assembly (MT2) is actuated. Thus, when the second traction assembly (MT2) is actuated to bring the movable wall back toward the front of the container, the resistive torque of the first traction assembly (MT1) will be reduced. Fig. 6 schematically shows a first traction assembly and a second traction assembly of the movable partition (10) according to another example of a vehicle according to the invention.

[0062] According to this example, the first traction set (MT1) comprises:

[0063] - a first speed reducer (R1) mounted between the first motor (M1) and the first winding means (E1),

[0064] - a first clutch (B1) mounted between the first speed reducer (R1) and the first winding means (E1),

[0065] - a second speed reducer (R2) mounted between the first motor (M1) and the second winding means (E2),

[0066] - a second clutch (B2) mounted between the second speed reducer (R2) and the second winding means (E2).

[0067] Preferably, the first and second clutches (B1, B2) are controllable clutches, and the control unit is configured to engage the first and second clutches (B1, B2) when the first traction assembly (MT1) is actuated and to disengage the first and second clutches (B1, B2) while the second traction assembly (MT2) is actuated. Thus, when the second traction assembly (MT2) is actuated to bring the movable wall toward the front of the container, the resistive torque of the first traction assembly (MT1) will be reduced.

[0068] Fig. 7 schematically shows a first traction assembly and a second traction assembly of the movable partition (10) according to yet another example of a vehicle according to the invention.

[0069] According to this example, the first traction set (MT1) comprises:

[0070] - a first speed reducer (R1) mounted between the first motor (M1) and the first winding means (E1),

[0071] - a first freewheel means (RL1) mounted between the first speed reducer (R1) and the first winding means (E1),

[0072] - a second speed reducer (R2) mounted between the first motor (M1) and the second winding means (E2), - a second freewheeling means (RL2) mounted between the second speed reducer (R2) and the second winding means (E2). The first freewheeling means (RL1) and a means (usually mechanical) for applying a driving torque to the first winding means (E1) when the first motor (M1) rotates in a first rotational direction in order to pull on the first flexible mechanical connection (14a) (as indicated by a downward arrow on the connection 14a, on the left in Fig. 7) and for removing or greatly reducing a resistive torque of the first traction assembly (MT1) when the second motor (M2) rotates in a rotational direction in order to pull on the third flexible mechanical connection (14c) (as indicated by an upward arrow on the connection 14c, on the left in Fig.7), i.e. when an opposing traction is applied to the first flexible mechanical connection (14a) by the second traction assembly (MT2).

[0073] The same applies to the second freewheeling means (RL2). Such freewheeling means are known and will therefore not be described in further detail.

[0074] Fig. 8 schematically shows a first traction assembly and a second traction assembly of the movable partition (10) according to yet another example of a vehicle according to the invention.

[0075] According to this example, the first motor (M1) is capable of rotating in both directions of rotation and the control unit is configured to:

[0076] - rotate the first motor (M1) in a first direction of rotation to pull the movable partition (10) towards the rear of the container (1), and to

[0077] - rotating the first motor (M1) in a second direction of rotation opposite to the first direction of rotation when and while the second motor (M2) is activated in one direction of rotation in order to pull on the third flexible mechanical connection (14c) to pull the movable partition (10) towards the front of the container (1).

[0078] This also makes it possible to eliminate or greatly reduce a resistive torque of the first traction assembly (MT1) when the second motor (M2) rotates in one direction of rotation in order to pull on the third flexible mechanical connection (14c) to pull the movable partition (10) towards the front of the container (1). According to this example, the first motor (M1) does not have to deliver a lot of power when it rotates in the second direction of rotation; it is sufficient that it accompanies the reverse rotation of the first winding means (E1) and the second winding means (E2) when and while the second motor (M2) is put into operation to pull the movable partition (10) towards the front of the container (1).

[0079] In the examples of Figures 6, 7 and 8, an alternative configuration may consist of not putting a gearbox (G) and connecting the first motor directly in line with the two reducers (R1, R2). In this case, the first motor may for example be a motor whose motor shaft is accessible from both sides, or it could be two motors whose motor shafts are preferably aligned and preferably rotating at the same speed, in one direction as in the other.

[0080] In some examples, the transmission ratio of the first speed reducer (R1) (output speed divided by input speed) is between 1 / 2 and 1 / 50.

[0081] In some examples, the first speed reducer (R1) and the second speed reducer R2 have the same transmission ratio.

[0082] In some examples, the first speed reducer (R1) comprises a plurality of speed reducers connected in cascade (in series).

[0083] In some examples, the second speed reducer (R2) comprises a plurality of speed reducers connected in cascade (in series).

[0084] In some examples, the second transmission (T2) comprises a speed reducer (R3) and the vehicle comprises means for reducing a resistive torque of the second traction assembly (MT2) when and while the first traction assembly (MT1) is activated to pull the movable partition towards the rear of the container.

[0085] According to a first example, the second motor (M2) is capable of rotating in both directions of rotation and the control unit is configured to:

[0086] - rotating the second motor (M2) in a first direction of rotation to pull the movable partition (10) towards the front of the container (1), and to - rotating the second motor (M2) in a second direction of rotation opposite to the first direction of rotation when and while the first motor (M1) is put into operation to pull the movable partition (10) towards the rear of the container (1)-

[0087] According to another example, the second traction assembly (MT2) comprises a third clutch (not shown) mounted between the speed reducer (R3) and the third winding means (E3). Preferably, the third clutch is a controllable clutch and the control unit is configured to disengage the third clutch when and while the control unit rotates the first motor (M1) in the first rotational direction to pull the movable partition toward the rear of the container, and to engage the third clutch when and while the control unit rotates the second motor (M2) in a rotational direction to pull the movable partition toward the front of the container.

[0088] In some examples, the first and second flexible mechanical links (14a, 14b) are cables or chains. In some examples, the third flexible mechanical link (14c) is a cable or a chain.

[0089] The first motor (M1) is for example a hydraulic motor and the second motor (M2) is for example an electric motor.

[0090] In some examples, the container (1) is fixedly connected to the vehicle. In some examples, the first flexible mechanical connection (14a) and the second flexible mechanical connection (14b) form a single flexible mechanical connection. In some examples, the single flexible mechanical connection is loosely connected to the movable partition (10). By "loosely connected" it is meant that the single flexible mechanical connection is not fixedly connected to the movable partition (10) but that the single flexible mechanical connection can move freely relative to the partition. Examples of such a single flexible mechanical connection are provided in patent application WO201 9154514 (see Figs. 10, 11 and 12 and their description). Preferably, the single flexible mechanical connection is a cable, for example a braided steel cable, or a chain.

[0091] In Figures 5 to 8, the first motor (M1) is connected to the inputs of the two speed reducers (R1, R2) via a gearbox (G) allowing an angle transmission between the motor shaft and the input shafts of the speed reducers (R1, R2).

[0092] Instead of having two speed reducers (R1, R2) mounted as shown in Figures 5 to 8, a single speed reducer may alternatively be provided mounted between the first motor (M1) and the gearbox (G). If so, the clutch (B) of the example in Fig. 5 will be mounted downstream of the speed reducer, as shown in Fig. 9. In the example in Fig. 9, the clutch (B) is preferably a controllable clutch, and the vehicle comprises a control unit (not shown) configured to engage the clutch (B) when and while the first traction assembly (MT1) is actuated and to disengage the clutch (B) when and while the second traction assembly (MT2) is actuated.

[0093] In Figures 1 to 9, the second traction assembly (MT2) acts on a single flexible mechanical connection (14c), but it is alternatively possible to provide several flexible mechanical connections, for example a fourth flexible mechanical connection (14d) one end of which is connected to a left part of the movable partition and a fifth flexible mechanical connection (14e) one end of which is connected to a right part of the movable partition, the opposite ends of the fourth and fifth flexible mechanical connections being connected together to one end of the third flexible mechanical connection (14c), an opposite end of the third flexible mechanical connection (14c) being connected to the third winding means (E3), as for example illustrated in Fig. 10 which also shows four angle return pulleys. In some examples, the third, fourth and fifth flexible mechanical connections (14c, 14d, 14e) are cables or chains.

[0094] In this example, the first traction set (MT1 ) may be any first traction set (MT1 ) as described above and the second traction set (MT2) may be any second traction set (MT2) as described above.

[0095] The invention also relates to a module or a kit comprising the first traction assembly (MT1) and the second traction assembly (MT2) as well as optionally the control unit as described above, said module or kit being able to be mounted on a vehicle whose container (1) is provided with the movable partition (10) as well as flexible mechanical connections (14a, 14b, 14c, 14d, 14e) and pulleys as described above.

[0096] The present invention has been described in relation to specific embodiments, which are of purely illustrative value and should not be considered as limiting. In general, it will be obvious to those skilled in the art that the present invention is not limited to the examples illustrated and / or described above. The presence of reference numbers in the drawings cannot be considered as limiting, including when these numbers are indicated in the claims.

[0097] The use of the verbs "comprendre", "include", "comprendre", or any other variant, as well as their conjugations, cannot in any way exclude the presence of elements other than those mentioned.

[0098] The use of the indefinite article "un", "une", or the definite article "le", "la" or "I'", to introduce an element does not exclude the presence of a plurality of these elements.

[0099] An aspect of the invention may also be described as follows: a vehicle on which is mounted a container (1) for transporting materials, said container comprising a movable partition (10) extending transversely inside the container. The vehicle comprises a first traction assembly (MT 1 ) capable of pulling on a pair of cables (14a, 14b) whose front parts are connected on either side of the partition (10) in order to pull the partition (10) towards the rear of the container to unload materials from the vehicle.

[0100] The vehicle also comprises a second traction assembly (MT2) which can then pull on one or more cables (14c, 14d, 14e, 14f) the front part or parts of which are connected to the movable partition (10) in order to pull the movable partition (10) towards the front of the container in order to replace it in an initial position at the front of the container before loading materials again.
