Description
[0001] The present invention relates to a cabin mounting system and a cabin mounting for vehicles, which enables the cabin of a vehicle to be attached to or on the chassis. Document EP2650195 A2 shows the preamble of the independent claim.
[0002] Vehicles specifically designed for off-road use are employed in demanding working environments. These vehicles can include construction vehicles, such as tracked vehicles, excavation vehicles, forestry vehicles for processing timber, or agricultural vehicles.
[0003] 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.
[0004] Due to the vehicle's use in open terrain and the associated working environment, dirt ingress on and inside the vehicle is unavoidable. This leads to soiling beneath the vehicle cab, which can impair the suspension travel, especially in cabs with movable mountings. Additionally, the dirt ingress can cause noise, as existing gaps between moving components of the cab mounting can become filled with dirt particles. The object of the invention is to avoid these problems. This object is achieved by the invention according to the main claim. Further embodiments of the invention are described in the dependent claims.
[0005] The invention relates to a cabin mounting comprising a chassis bracket, comprising 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 a shaped element is attached to the lower bearing plate and / or the chassis plate so that any dirt that comes into contact with it is wiped off by the shaped element.
[0006] The molded element reduces the surface area, especially in the area of the lower bearing plate. Typically, the lower bearing plate is welded or bolted to the chassis plate, creating a 90-degree angle or an acute angle between them. This transition and the adjacent surface area of the chassis and lower bearing plate are particularly prone to dirt accumulation. The molded element reduces this surface area and covers the angle between the two plates. This prevents dirt buildup and allows the cabin mounting to function with reduced maintenance.
[0007] In further training, the form element can be made of metal or plastic.
[0008] When manufactured from plastic, the component offers greater flexibility and deformability. It can be attached to the chassis mount by gluing, screwing, wedging, clamping, or plastic welding. Metal components, on the other hand, offer increased durability and lifespan. In this case, they can be welded to the chassis mount.
[0009] In one version, the shaped element can be provided on one side of the lower bearing plate.
[0010] The lower bearing plate is vertically oriented when installed, so that the side surfaces point horizontally. The molded element can rest against one of these side surfaces. This can be advantageously positioned on the side that accumulates a significant amount of dirt during vehicle operation and can be oriented towards the outside of the vehicle or in the direction of travel.
[0011] In a training setup, the form element can be provided on both sides of the lower bearing plate.
[0012] The double-sided arrangement ensures comprehensive prevention of dirt buildup. This covers all driving situations and provides broader protection for the cabin mounting.
[0013] In a further training course, a hydraulic actuator can be provided between the cabin plate and the chassis plate.
[0014] 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.
[0015] In a training setup, a position sensor can be provided on the lower bearing plate, which interacts with a linkage to guide the upper and lower bearing plates.
[0016] 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.
[0017] The invention further relates to a cabin mounting system comprising at least two of the aforementioned cabin mountings, 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.
[0018] 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.
[0019] 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 predominantly 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 or recess in its center, which serves to receive part of the upper bearing plate 32. The opening 33 can be milled, drilled, or punched.
[0020] 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 rigidly connected to the cabin plate 31 in a central area, predominantly vertically. The upper bearing plate 32 has two parallel webs attached to the cabin plate 31 at a fixed distance and has two free ends. At one end of the upper bearing plate 32, the free ends are connected to each other by a bolt, screw, or metal rod. The bolt sits within the opening 33 of the lower bearing plate 22 and ensures a movable connection between the lower 22 and the upper bearing plate 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.
[0021] A shaped element 40 is attached at the transition between the lower bearing plate 22 and the chassis plate 21. The shaped element 40 can be attached to both plates simultaneously or to only one of them. The shaped element 40 can be made of plastic or metal. It can be attached to one or both plates by means of a snap-fit mechanism, by screws, or by welding. The shaped element 40 has a downward slope towards a free end of the chassis plate 21. In the installed position on the vehicle, the downward slope points in the direction of gravity. This shape ensures that any dirt accumulating is directed away from the lower bearing plate 22 by the force of gravity, preventing its accumulation. This prevents the accumulation of dirt particles and ensures that the movement of the lower 22 and upper bearing plate 32 is not impaired.The form element 40 can form an angle of 10 to 80 degrees to the horizontal plane in its installed position. Furthermore, in conjunction with exposure to water, such as rain or active cleaning of the vehicle, the removal of dirt particles at the transition point can be simplified, thereby reducing maintenance requirements.
[0022] 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 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.
[0023] Fig. 2Figure 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, 30 can be adjusted, or active damping of the cabin can be enabled. The hydraulic actuator is attached to the chassis bracket 20 and to the cabin bracket 30.
[0024] In this application, the cabin moves differently relative to the vehicle chassis. This movement results in a relative movement of the upper 32 and lower bearing plate 22. 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.
[0025] The two bearing plates are connected to each other by a web located between both ends of the upper bearing plate 32. It is also possible that only the lower bearing plate 22 has two free ends. 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.
[0026] Fig. 3Figure 1 shows another view of the cabin mounting 10. The form element 40 is visibly attached to one side of the lower mounting plate 22. The height of the form element 40 can be variably set, thus changing the angle between the top of the form element 40 and the horizontal in the installed position. The form element 40 is attached to the chassis plate 21 by a screw connection and to the lower mounting plate 22 by another screw connection. The connection can also be made by a snap mechanism. If the form element 40 is made of metal, a welded connection can also be provided.
[0027] The position sensor 50, mounted on the lower bearing plate 22, is connected to a controller (not shown). This controller detects and calculates the cabin's movement, enabling active control of the hydraulic actuator 70. The sensor 50 can be mounted on the lower bearing plate 22. If the installation situation allows, it can also be mounted 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, eliminating the need for an additional position sensor 50.
[0028] Figure 4Figure 1 shows the cabin mounting 10, which is attached to a section of the axle housing of a vehicle. In addition to the features described above, the cabin mounting 10 includes a Panhard rod 80, which connects one assembly of the cabin mounting 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 mounting 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 work tasks.
[0029] The cabin mounting system can have at least one position sensor 50 on one side of the cabin mounting, however, it is also possible to mount the position sensor 50 on both sides, so that an unequal height on both sides of the cabin mounting 10 can be detected.
[0030] 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.
