- the invention also relates to a motor vehicle engine comprising such an anti-recoil device.
- the invention relates to a motor vehicle comprising such a box, such a motor or such an anti-recoil device.
- a motor vehicle is generally equipped with an engine, for example an internal combustion engine, arranged in an engine compartment at the front of the motor vehicle.
- the motor vehicle may be subjected during its use to shock, particularly a front shock also called frontal impact.
- a front shock also called frontal impact.
- the front of the motor vehicle is generally equipped with elements that deform and / or break and / or recede.
- elements located at the front of the motor vehicle, in particular the engine can move back in the event of a front impact.
- the engine compartment is separated from the passenger compartment occupied by one or more occupants by a simple apron.
- This apron is usually a steel sheet. Also, in the event of a frontal impact, if the engine and / or front elements retreat beyond a threshold value, the engine and / or the front elements deform or even pass through the deck.
- the object of the invention is to provide an anti-recoil device of an element arranged in the engine compartment before overcoming the disadvantages above.
- the invention makes it possible to provide an anti-recoil device of an element that is simple, reliable and easy to implement.
- the invention relates to an anti-recoil device of a motor vehicle engine during a front impact, the anti-recoil device comprising a first beam-type stop, intended to extend longitudinally or substantially longitudinally, in particular extending between the engine and a chassis element of the motor vehicle, the first stop having at least one pointed end, in particular a beveled end, so that the at least one end is fixed in the element chassis or in the engine in case of impact.
- the anti-recoil device may comprise a first means for fixing the first stop on the chassis element or on the motor vehicle element, in particular a first bridge-shaped fastening means.
- the anti-recoil device may comprise a second stop, in particular a reinforcement, and a second means for fixing the second stop on the motor vehicle element or on the chassis element.
- the second stop may be a plate, in particular a metal plate.
- the invention also relates to a motor vehicle body, in particular a body comprising a front cradle type frame element intended to receive a first means for fixing a first abutment or a second means for fixing a second abutment, the body comprising an anti-recoil device as defined above.
- the invention also relates to a motor vehicle engine, in particular an internal combustion engine comprising an oil sump, intended to receive a first means for fixing a first stop or a second means for fixing a second stop, the engine comprising an anti-recoil device as defined above.
- the invention relates to a motor vehicle, including a motor vehicle comprising a motor in the front, the motor vehicle comprising a box as defined above or a motor as defined above or an anti-recoil device as defined above.
- Figure 1 schematically shows a top view of a motor vehicle according to one embodiment.
- FIG. 2 represents a perspective view of a box comprising an anti-recoil device of an element according to one embodiment, without being subjected to a front impact.
- FIG 3 shows a perspective view of the box comprising the anti-recoil device of an element according to the embodiment, following a front impact.
- Figure 4 shows a perspective view of a detail of the anti-recoil device of an element according to the embodiment.
- the direction in which a motor vehicle usually moves in a straight line is defined as the direction longitudinal.
- the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called transverse direction.
- the third direction, perpendicular to the other two, is named vertical direction.
- the "forward" direction corresponds to the direction in which the motor vehicle usually moves in the longitudinal direction, and is opposite to the "back" direction.
- a motor vehicle 1 comprises a motor 10.
- the engine 10 may for example be an internal combustion engine with an oil sump 15.
- the engine 10, more precisely its oil sump 15, receives a second attachment means 121 of a second stop 120.
- a box 3 of the motor vehicle 1 comprises a frame member 4, for example of the front cradle type.
- An anti-recoil device 100 of an element such as, for example, the motor 10, comprises the first abutment 110.
- This first abutment 110 is preferably a beam, for example an angle beam, IPN, or tubular with a circular section, square, rectangular or oval.
- This first stop 110 extends longitudinally or substantially longitudinally, in particular between the motor 10 and the front cradle 4 of the motor vehicle 1.
- the anti-recoil device 100 preferably comprises the first attachment means 130 of the first stop 110 on the front cradle 4.
- the anti-recoil device 100 preferably comprises the second stop 120, for example a stop 120 of the reinforcement type.
- the second stop 120 is preferably a plate, for example a metal plate.
- the anti-recoil device 100 then preferably comprises the second attachment means 121 of the second stop 120 on the motor vehicle engine 1, for example on its oil sump 15. This second attachment means 121 can comprise one or several screws passing through for example the second stop 120.
- the first attachment means 130 is fixed on the front cradle 4, for example at a front edge 4 'of the front cradle 4.
- the first fixing means 130 has, for example, a shape trigger guard.
- the first fixing means 130 is for example made of steel and is welded to the front cradle 4, preferably of steel.
- the first fastening means 130 is advantageously traversed by the first stop 110 in order to be able to guide it easily.
- the first attachment means 130 is fixed to the first stop 110, for example by welding.
- the rear end 111 of the first stop 110 has a shape adapted to facilitate its insertion into the front cradle 4. Thus, this end 111 is preferably pointed, for example beveled.
- a clearance J between the second stop 120 and the first stop 110 is provided.
- This clearance J is dimensioned so as to prevent the transmission of vibrations and to allow the movements or movements of the motor 10 to the front cradle 4, during the use of the motor vehicle 1.
- the first and second stops come closer.
- the first stop 110 and the second stop 120 come into contact.
- the clearance J is fully compensated by the recoil of the motor 10.
- the first attachment means 130 deforms, while maintaining the first stop 110, so that the rear end 111 of the first stop 1 10 comes into contact with, or even sinks into, the cradle before 4, for example at the level of an upper shell of the front cradle.
- This kinematics is favored by guiding in the longitudinal direction of the first stop 110 by the first attachment means 130.
- the first stop 110 at least its rear end 111, then necessarily comes into the cradle before 4 and transmits the forces of the engine 10 to the cradle before 4.
- the front cradle 4 undergoes a deformation following the forces transmitted by the first stop 110, efforts having prevented, at least in part, the recoil of the motor 10.
- the forces related to the recoil of the engine 10 during a frontal impact are taken up by the first stop 110 and, possibly, by the deformation of the front cradle 4.
- the recoil of the engine 10 is then limited and the deck separating the engine compartment of the passenger compartment is not or little impacted. This results in an absence of intrusion into the passenger compartment thus eliminating the risk of injury to the occupants of the motor vehicle.
- the engine for example via its oil sump or a gearbox, which receives the first attachment means of the first stop.
- the body for example the front cradle, which receives the second attachment means of the second stop (variant not shown).
- the element 10 may be another element than an internal combustion engine, for example an electric motor.
- the element 10 may for example be a bulky and / or heavy propulsion battery disposed at the front of the vehicle.
- the solution thus achieves the object sought to limit the retreat of a motor vehicle engine during a front impact and has the following advantages:
- first stop 110, the second stop 120 and the first attachment means 130 being for example steel parts, for example obtained by conventional manufacturing processes,
- the invention is particularly well suited to a motor vehicle having a motor compartment at the front. It provides better security for the occupant (s) of the vehicle during a frontal impact. It relates to an anti-recoil device of a motor vehicle element during a front impact. It also relates to a box comprising such an anti-recoil device. It still relates to an engine comprising such an anti-recoil device. Finally, it relates to a motor vehicle comprising such a box or such an engine or such an anti-recoil device.
