CABIN STORAGE SYSTEM AND CABIN STORAGE

Description

[0001] The present invention relates to a cabin mounting for vehicles, which enables the cabin of a vehicle to be attached to or on the chassis. The cabin mounting comprises a chassis bracket with a chassis plate designed for attachment to a vehicle chassis, a lower bearing plate attached to the chassis plate with an opening designed for connection to an upper bearing plate, a cabin plate designed for attachment to a vehicle cabin, and an upper bearing plate attached to the cabin plate with a U-shaped structure designed to be movably held in the opening of the lower bearing plate, so that the chassis bracket and the cabin bracket are movable relative to each other.

[0002] Such a cab mounting for a commercial vehicle, in the form of a rear cab mounting, is known, for example, from EP 2 650 195 A2. The cab mounting comprises a cross member which is connected on both sides at two pivot points to a bearing assembly. The bearing assembly establishes a connection between the cross member and the respective frame longitudinal members and comprises, on the one hand, a spring-damper unit and, on the other hand, a lateral guide which absorbs lateral forces occurring in the mounting. The spring-damper unit enables vertical movement of the cab up to a predetermined maximum vertical movement. The lateral guide, in particular one in a guide element or...A guide roller, movably mounted in an elongated hole and attached to the crossmember via a bracket, allows the crossmember, together with the bracket and guide roller, to perform a vertical movement relative to the frame longitudinal member with its attached bearing block and guide element. Fixing the guide roller transversely and longitudinally to the vehicle's longitudinal axis within the elongated hole reliably ensures that any lateral forces are absorbed. Furthermore, it guarantees that in the event of a spring-damper unit failure, the cab remains securely connected to the frame longitudinal member.

[0003] Off-road vehicles are used in demanding working environments. These vehicles can include construction vehicles, such as tracked vehicles, excavation vehicles, forestry vehicles for processing timber, or agricultural vehicles.

[0004] The operating location is usually undeveloped terrain with existing inclines. Especially on slopes and when operating on dirt or scree, the vehicle can tilt sharply, potentially tipping over or rolling in the event of an accident. In this situation, the operator must be protected as much as possible from injuries, both from potential collisions within the cab and from being ejected. Additionally, it is necessary to secure the cab to the vehicle in such a way that it cannot break away if the vehicle tips over, thus maintaining a safety cell for the operator even in the event of a rollover.

[0005] Due to the vehicles' use in open terrain and the associated working environment, dirt inevitably accumulates on and inside the vehicles. This leads to soiling beneath the vehicle cab, which can impair the suspension travel, especially in cabs with flexible mountings. Additionally, the dirt ingress can cause noise, as dirt particles can fill existing gaps between moving components of the cab mounting.

[0006] The object of the invention is to avoid the problems mentioned above. This object is achieved by the invention according to the main claim. Further embodiments of the invention are described in the dependent claims.

[0007] The invention relates to a cabin mounting comprising a chassis bracket having a chassis plate designed for attachment to a vehicle chassis, a lower bearing plate attached to the chassis plate with an opening designed for connection to an upper bearing plate, a cabin bracket comprising a cabin plate designed for attachment to a vehicle cabin, an upper bearing plate attached to the cabin plate with a U-shaped structure designed to be movably held in the opening of the lower bearing plate, so that the chassis bracket and the cabin bracket are movable relative to each other, wherein at least one flexible element is attached to the chassis plate and to the upper bearing plate, such that the relative movement of the chassis bracket and the cabin bracket moves the flexible element, enabling surface contact between the flexible element and the chassis bracket.

[0008] The cab mounting is moved by the passive up-and-down movement of the cab and, depending on the equipment, by active cab damping. The flexible element, which is attached at one end to the cab side and at the other end to the chassis side, moves along with the cab during this up-and-down motion. Through this movement and contact with the chassis surface, the flexible element scrapes away dirt from the cab mounting system, including from the chassis side. This prevents dirt from accumulating and avoids the excessive build-up of a layer of grime, such as soil, stones, or twigs. This is particularly advantageous for vehicles used in agriculture, forestry, and construction. Avoiding or reducing the build-up of dirt ensures the smooth operation of the cab mounting and prevents noise during the up-and-down movement.Additionally, cleaning intervals can be extended and the cleaning effort reduced.

[0009] In a further training, the flexible element can be provided in the form of a band, and attached at the ends to the chassis plate and the upper bearing plate.

[0010] The flexible element's strip shape provides a large surface area and can cover a correspondingly wide area. This shape also allows for easy replacement and maintenance of the flexible element. Suitable materials include thin rolled sheets or plastic strips.

[0011] In one design, the flexible element can be in the form of a rope or cord, and attached at both ends to the chassis plate and the upper bearing plate.

[0012] The flexible element's shape makes it particularly flexible. This flexibility and shape allow it to be easily deformed and, depending on the chosen length, to clean a large surface area of ​​dirt.

[0013] In a training course, the flexible element can be made of plastic or metal.

[0014] A flexible element made of plastic offers greater flexibility and deformability. It can be attached to the chassis mount by gluing, screwing, wedging, clamping, or plastic welding. A flexible element made of metal can offer increased durability and lifespan. In this case, it can be welded to the chassis mount.

[0015] In a further training course, the flexible element can be provided on one side of the upper bearing plate.

[0016] The upper bearing plate is vertically oriented in the installation position, so it has two sides. The U-shaped structure is closed on one side by a bolt, screw, or welded bridge. The flexible element is attached to one side of the U-shaped structure. This flexible element can be advantageously positioned where dirt accumulation is most pronounced or where contamination has the greatest impact on the cabin mounting's functionality.

[0017] In one version, the elastic element can be provided on both sides of the upper bearing plate.

[0018] A double-sided arrangement ensures that no dirt can build up on the chassis plate or on or around the linkage between the upper and lower bearing plates, which could lead to noise or impaired function.

[0019] In a training course, a hydraulic actuator may be provided between the cabin plate and the chassis plate.

[0020] The actuator ensures that the cabin's mounting can be actively controlled. This allows movements detected by vehicle sensors to be used to reduce their impact on the cabin. Furthermore, the actuator enables damping.

[0021] In a further training, a position sensor can be provided on the lower bearing plate, which interacts with a linkage to guide the upper and lower bearing plates.

[0022] The position sensor, which interacts with the linkage that acts as a bearing between the lower and upper bearing plates, detects the vertical distance between these two plates. The position sensor can be either an angle sensor or a distance sensor, as long as a distance can be calculated from the measured data. This calculated distance enables active cabin suspension. This suspension actively controls existing hydraulic actuators, thus providing regulation. Furthermore, a safety-relevant condition can be detected, allowing the hydraulic actuators to be actively moved to a specific position that ensures maximum operator safety.

[0023] The invention further comprises a cabin mounting system comprising at least two cabin mountings according to the invention, wherein a Panhard rod is movably held between the cabin plate of one cabin mounting and the lower bearing plate of the further cabin mounting.

[0024] The invention and its further developments are explained using the characters. This shows Figure 1 a detailed view of a design; Figure 2 a version in an installed state in a vehicle; Figure 3 another version in an installed state; Figure 4 a version on an axle module of a vehicle.

[0025] In Fig. 1The cabin mounting 10 is shown in an isometric view. The cabin mounting 10 has a two-part form. The lower part represents the chassis mount 20, and the upper part the cabin mount 30. The chassis mount 20 includes a chassis plate 21, which is designed to be attached to a part of the vehicle, preferably a component of the chassis, by means of screws or welding. A lower bearing plate 22 is firmly connected to the chassis plate 21 such that it extends perpendicular to the chassis plate 21 and is located in a central area of ​​the chassis plate 21. The connection can be secured by welding, screws, or rivets. The lower bearing plate 22 has an opening 33 in its center, which serves to receive part of the upper bearing plate 32. The opening 33 can be milled, drilled, or punched.

[0026] The cabin mount 30 has a cabin plate 31 designed to be attached to a component of the cabin. For this purpose, the cabin plate 31 may have holes for screws, but it can also alternatively be welded. An upper bearing plate 32 is vertically fixed to the cabin plate 31 in a central area. The upper bearing plate 32 has two parallel webs as free ends, which are attached to the cabin plate 31 at a fixed distance. At one end of the upper bearing plate 32, the free ends are connected to each other by a bolt, a screw, or a metal rod. The bolt sits within the opening 33 of the lower bearing plate 22 and ensures a movable connection between the lower and upper bearing plates 22, 32, and thus also between the chassis mount 20 and the cabin mount 30.The geometric height and width of the opening 33 determine the relative mobility of the cabin mount 30 and the chassis mount 20.

[0027] The flexible element 40 is attached to one end of the bolt on the upper bearing plate 32 by means of a screw connection, and its other end is simultaneously attached to the chassis plate 21. The flexible element 40 is shown as a strip of sheet metal, but a plastic band can also be used instead. The length of the flexible element 40 is dimensioned such that it is never under tension, but always has some slack. This slack is chosen so that surface contact is established between the flexible element 40 and the chassis mount 20. The relative movement of the cabin and chassis mount 20 causes the flexible element 40 to move along with it, so that the movement and the surface contact generate a sliding or wiping motion.The movement and surface contact ensure a constant wiping or grinding away of adhering dirt particles that settle on the surfaces. Together with the horizontal movement of the vehicle during operation, this prevents or reduces the build-up of dirt on the cabin mounting 10.

[0028] The chassis and cabin mounts 20, 30 are movably connected to each other by the linkage 60. The linkage 60 primarily serves to detect the distance between the chassis and cabin mounts 20, 30. For this purpose, a position sensor 50 in the form of an angle sensor 50 is attached to the lower bearing plate 22, which detects the angle of deflection of the linkage 60. The distance can be calculated or directly measured by means of an electrical signal output from the sensor 50, which can then be processed by a control unit. This distance can be used to control active cabin damping.

[0029] Fig. 2 Figure 1 shows the cabin mount 10 in an installed position in the vehicle. The cabin mount 10 is attached to a chassis area of ​​the vehicle by means of the chassis bracket 20 and the chassis plate 21. This can be done by means of screws, rivets, welding, or the like. The cabin mount 10 is attached to the underside of the cabin by means of the cabin bracket 30 and the cabin plate 31. This connection can also be made by means of screws, rivets, or welding. A hydraulic actuator 70 is attached to one side of the cabin mount 10. This actuator serves to actively adjust the cabin mount 10, so that the distance between the cabin and the chassis bracket 20 can be adjusted, or active damping of the cabin can be enabled.

[0030] In this application, the cabin moves differently relative to the vehicle chassis. This movement results in a relative movement of the upper and lower bearing plates 22, 32 to each other. The movement of the bearing plates can be detected by means of the linkage 60 and the position sensor 50, and the hydraulic actuator 70 can be actively controlled from this.

[0031] The relative movement of the upper and lower bearing plates 32, 22 causes the flexible element 40 to move along with it, so that the movement results in surface contact between the flexible element 40 and the chassis mount 20.

[0032] The two bearing plates are connected to each other by a web or bolt located between the two free ends of the upper bearing plate 32. It is also possible for the lower bearing plate 22 to have two ends instead. In the event of a vehicle rollover or a strong force being applied to the cabin, the bearing plates maintain the connection between the cabin and the vehicle, thus preventing it from being rolled over or becoming detached.

[0033] Fig. 3Figure 10 shows another view of the cabin mounting. The flexible element 40 is held to the upper bearing plate 32 by a screw. However, the connection can also be made by riveting, bonding, or welding. The flexible element 40 can have a mounting tab through which a strap is threaded. This strap can be made of metal or plastic, be a sheet metal strip, or be woven from metal or plastic. The length of the flexible element 40 is designed so that even at maximum cabin deflection, the flexible element 40 remains in contact with the surface at all times.

[0034] The position sensor 50 is connected to a controller, which is not shown here. The controller can detect and calculate the cabin's movement, enabling active control of the hydraulic actuator 70. The sensor 50 can be mounted on the lower bearing plate 22, or, if the installation situation allows, on the upper bearing plate 32. The sensor 50 can also be a linear position sensor. Alternatively, the hydraulic actuator 70 can have its own position measurement capability.

[0035] Figure 4Figure 1 shows the cabin mounting system, which consists of at least two cabin mounts 10 attached to a section of the axle housing of a vehicle. In addition to the features described above, the cabin mount 10 includes a Panhard rod 80 that connects one assembly of the cabin mount 10 to another on the opposite side of the cabin. The Panhard rod 80 limits the degrees of freedom and prevents lateral movement of the cabin structure, which is attached to the cabin plate 31. This allows the cabin mount 10 according to the invention to be integrated into a vehicle as a cabin mounting system. The system is adaptable to any cabin dimensions and enables its use in a wide range of vehicles for various applications.

[0036] The cabin mounting system has at least one position sensor 50 on one side of the cabin mounting 10. The sensor 50 can also be provided on both sides of the cabin mounting 10, so that a different height on each side can be detected.

[0037] Particularly in the area of ​​vehicle axles, significant dirt accumulation and build-up occur. The cabin mounting 10 prevents this dirt build-up in the critical area of ​​the moving components. Typically, this dirt accumulation can lead to jamming of the moving parts, especially the cabin mounting 10, which then prevents or severely restricts its function. Furthermore, the movement produces noises that are perceived as disturbing. The cabin mounting 10 and the system according to the invention ensure proper functioning.
