Description

DESCRIPTION

EQUIPMENT TO IMMOBILIZE A HEAVY VEHICLE

OBJECT OF THE INVENTION

The object of the present invention is to define a new piece of equipment that is installed in a heavy vehicle and that is designed to immobilize said vehicle by means of the automatic activation, by a user from the cabin, of positioning and adjustment systems of some chocks on the wheels of the vehicle.

The field of application of the invention is included within the industrial sector related to vehicle immobilization systems and equipment, and specifically, it is aimed at heavy vehicles.

STATE OF THE ART

It is known, within this industrial sector, that wedges can be used to immobilize vehicles. These shims are used to immobilize heavy vehicles in the event of breakages, accidents or the like, and are removable elements that do not belong to the body or chassis of the vehicle.

In this sense, it is known that one of the main problems presented by conventional shims is that the driver has to be outside the vehicle to place them on the wheels of the heavy vehicle, for example, a truck or the like, in order to consequent danger to traffic when the vehicle is on a busy road.

Another notable drawback of the known chocks is that they can be stolen or stolen in the absence of surveillance of the vehicle, which can cause undesired movements of the truck on the road itself.

It is also known that these conventional chocks can be forgotten by the user of the heavy vehicle when he resumes the journey, with the consequent danger that this action could mean for a third party and/or for the integrity of the heavy vehicle itself.

Taking these aspects into account, the equipment object of the present invention is aimed at solving these existing and known problems with conventional shims, and for this, the present invention is based on integrating the shims into the structure of the heavy vehicle, and can be activated automatically from the cab by the driver.

In this sense, systems that integrate chocks or immobilization devices into the very structure of the vehicle are known, but it is known that they are based on complex mechanisms, which do not allow the chock to be correctly secured to the wheel, and that there is no indicator or means that allow the user to know if this immobilization is correct, having to get off the heavy vehicle to check it with the previously indicated risks.

Taking into account the systems and equipment known in the state of the art, the applicant does not know of equipment for the immobilization of heavy vehicles as effective as the one described and claimed below, being an equipment with which a correct fixation is ensured. of the chock with the wheel and with which the user can have a visual signal that confirms if the chock is in the working position immobilizing the wheel, or it is in the rest position and therefore there is no immobilization of the vehicle, and with which Therefore, all these previously mentioned drawbacks are overcome.

EXPLANATION OF THE INVENTION

The equipment that is the object of the present invention is designed to immobilize a heavy vehicle, and can be automatically activated from the vehicle cabin by the user or driver, and there is visual confirmation of the immobilization equipment's work or rest status.

Going into the detail of the invention, the team has the particularity of understanding:

a series of elements integrated into the driver's cabin, such as a control module, which comprises at least one means of actuating a system for positioning a chock on a wheel of the vehicle, with which the user or driver can immobilize at least one wheel automatically without having to leave the cab, avoiding the problems known in the state of the art; and at least one visual signal, preferably a light signal, for activating the system that allows the user or driver to be able to check the immobilization status of the vehicle, that is, depending on whether the visual signal is activated or not, the user can check if the system for positioning the various possible shims is in the immobilization position or in the rest position; and

a series of elements integrated into the vehicle chassis, such as:

a power take-off and which is in connection with the cabin control module, and where the power take-off communicates with a general valve and a compressor from which a main pipe departs from which in turn departs a plurality of hoses ; where the compressor communicates with at least one shim positioning system through said hoses; and where each of the chock positioning systems, having at least one system arranged on at least one wheel of the vehicle, comprises:

a support arm that is activated by a hose and is commanded from the control module; that at its upper end and fixed to the vehicle chassis it has at least one axis of rotation; that at its lower end it comprises a wedge that is fixed in position to adapt to the position of the wheel by at least one articulation axis, said articulation axis allowing the wedge to tilt and remain in contact with the wheel; and where the arm internally comprises a piston for adjusting the length of the arm and position of the shim, said piston being therefore in communication with the articulation axis of the shim; and

a lifting guide bar, which is mobile and allows the support arm to be raised, which is activated by a hose and commanded from the control module, which includes an internal piston that allows the length of the bar to be adjusted; which at one end is supported on the chassis of the vehicle with a guide and the opposite end is connected to a support bar that is associated in movement with the support arm, and may have articulation axes at both ends, one on the chassis and one on the other. another in the wedge itself, and where the guide bar helps position the wedge and provides rigidity to the wedge to immobilize the wheel;

a sensor, which can be light, proximity detection or similar, which is integrated into the vehicle chassis that allows detecting the position of the support arm on the vehicle chassis and that the visual signal of the control module is in communication ; that provides a visual signal to the user as to whether the support arm of the chock is deployed and in work position, that is, immobilizing the vehicle; or if the arm is folded on the chassis in the rest position and therefore there is no immobilization of the vehicle; and, where the equipment can comprise an anchor arranged on the vehicle chassis, which fixes the position of the support arm on the chassis in the rest position.

As previously mentioned, this equipment solves the problems known in the state of the art, and allows a driver from the cab to ensure correct fixing of a chock on at least one wheel of the heavy vehicle; and allows, in turn, to have a visual signal confirming said immobilization.

The equipment object of the present invention is intended to be installed in a heavy vehicle already in circulation where there is a power take-off and a compressor, or it can be installed at the time of manufacturing the heavy vehicle.

It must be taken into account that, throughout the description and the claims, the term "comprises" and its variants are not intended to exclude other technical characteristics or additional elements.
