[0002] Braking device for a car of an elevator system Technical field
[0003] The following description relates to a braking device for a car of an elevator system, comprising a braking device housing, wherein the braking device housing is designed to be received on the car and subjected to a braking force in a first transverse direction of the braking device, a brake shoe for receiving a brake lining and a brake lining received on the brake shoe, wherein the brake shoe is wedge-shaped with a first chamfer facing the braking device housing, wherein the braking device housing has a second chamfer corresponding to the first chamfer such that the brake shoe can slide off an upper braking position on the second chamfer, and wherein a spring element is arranged between the braking device housing and the brake shoe, pressing the brake shoe into the upper braking position.
[0004] Furthermore, the following statements concern a car for an elevator system, having at least one such braking device.
[0005] Furthermore, the following statements relate to an elevator system comprising an elevator shaft, a car movable in the elevator shaft and at least one such braking device arranged on the car.
[0006] Technical background
[0007] Elevator systems for transporting people and / or goods are an integral part of modern residential and commercial buildings. A typical elevator system comprises one or more elevator shafts, in each of which one or more cars are moved between landing positions by means of drives such as suspension drives or linear drives. TKE2401P-DEWO - 2 - February 2026
[0008] In elevator installations, it is known to install a braking device on the elevator car to brake the car in an emergency. Such a braking device is known, for example, from WO 2015 / 144686 Al or EP 3 405423 Al and is triggered, for instance, by a safety gear.
[0009] To ensure the highest possible level of safety, the elevator system's control system is typically designed to initiate braking in any hazardous situation, bringing the car to a standstill as quickly as possible. This is particularly important in the event of a complete power failure to the elevator system. Therefore, the braking device is advantageously designed to be actively held in the open position during operation, and in the event of a power failure, at least one brake shoe is automatically engaged with a stationary element (especially by the compressive force of a pre-tensioned spring).
[0010] While such an emergency stop is essential during a downward movement of the elevator car to prevent a potential fall, this is not necessarily the case during an upward movement. In this case, the elevator car comes to a standstill anyway due to the drive being switched off, provided it is heavier than any counterweight. Therefore, actively braking the upward movement is not only unnecessary but, from a safety perspective, must even be avoided, as an abrupt deceleration of the upward movement would cause passengers to hit their heads on the elevator car ceiling, posing a risk of injury.
[0011] With such braking devices, there is a need that they safely brake the elevator car when triggered during a downward movement, and at the same time do not impede the movement of the elevator car when triggered during an upward movement.
[0012] Based on this situation, the task at hand is to further improve a braking device with regard to the aforementioned need. TKE2401P-DEWO -3 - February 2026
[0013] Description - Technical Solution
[0014] The present problem is solved by the features of the independent claims. Advantageous embodiments are specified in the dependent claims, the description, and the drawings. Where technically feasible, the teachings of the dependent claims can be combined arbitrarily with those of the main and dependent claims.
[0015] In particular, the problem is solved by a braking device for a car of an elevator system, comprising a braking device housing, wherein the braking device housing is designed to be received on the car and subjected to a braking force in a first transverse direction of the braking device, a brake shoe for receiving a brake lining and a brake lining received on the brake shoe, wherein the brake shoe is wedge-shaped with a first chamfer facing the braking device housing, wherein the braking device housing has a second chamfer corresponding to the first chamfer such that the brake shoe can slide off an upper braking position on the second chamfer, wherein a spring element is arranged between the braking device housing and the brake shoe, pressing the brake shoe into the upper braking position.wherein both the first slope and the second slope each hold roller plates and wherein a linear roller bearing with a plate-shaped roller cage and rollers received therein is arranged between the first slope and the second slope and wherein the linear roller bearing is covered in a second transverse direction perpendicular to the first transverse direction by a retaining element held on the brake device housing.
[0016] The following sections explain advantageous aspects and subsequently describe preferred modified embodiments. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be explicitly stated.
[0017] Where ordinal numbers, for example "first", "second", etc., are used, for instance to designate a component, an element, a process step, or a procedural action, these ordinal numbers are intended solely for differentiation in the designation and do not indicate any dependencies or sequences. This means TKE2401P-DEWO - 4 - February 2026
[0018] In particular, a device does not need to have a "first component" to have a "second component." A device can also have a "first component" and a "third component" without necessarily having a "second component." Multiple units of the same ordinal number can also be provided, for example, multiple "first components."
[0019] According to the present understanding, an elevator system is designed, for example, with at least one vertical and / or horizontal elevator shaft and at least one elevator car, but can also have several elevator shafts and / or several elevator cars, in particular several elevator cars per elevator shaft.
[0020] For example, an elevator car is held and driven by a load-bearing element, wherein a drive device transmits a drive torque to the load-bearing element via a drive shaft. The load-bearing element is preferably connected to a counterweight associated with the elevator car. A drive device is particularly located in a machine room or in the shaft head. A load-bearing element is particularly designed as a rope, belt, strap, chain, or the like and carries tensile loads in the direction of its longitudinal extension. Alternatively, an elevator car is held and driven by a linear drive. A linear drive is, for example, formed from a primary part extending along the elevator shaft and a secondary part located on the elevator car.The primary part consists of coils arranged in a line, each with its own converter. An electric current is applied to the coil to generate a magnetic field when the elevator car is within the area of the respective coil, thus moving the car. The secondary part consists of a permanent or electromagnet that interacts with the magnetic fields of the coil.
[0021] The elevator car is preferably guided on at least one guide rail. In the case of an elevator car with a linear drive, the car can also be moved between several guide rails in the elevator shaft or in several elevator shafts. Preferably, the braking device is arranged on the elevator car such that a surface located on the guide rail is used as a braking surface by applying the brake pad to this surface. Alternatively, a braking surface can be formed on a separate profile in the elevator shaft, for example, against which the braking device secures the elevator car. TKE2401P-DEWO - 5 - February 2026
[0022] The brake device housing is arranged, in particular, on a movable brake release mechanism and, to initiate braking, is moved as a whole in the first transverse direction towards a braking surface. Preferably, the freedom of movement or the intended braking distance of the brake device housing or the brake device is set such that the brake pad contacts the braking surface in an upper position of the brake shoe and not in a lower position when the brake device is subjected to the braking force. The brake device housing then has a suitable device for being attached to the brake release mechanism, for example, a lug, a projection, and / or a recess.
[0023] If the brake shoe is wedge-shaped, one of the surfaces opposite the first inclined plane is, in particular, flat, i.e., parallel to a braking surface fixed in the elevator shaft, so that the brake pad makes full contact with this braking surface during braking. If a brake pad is attached to the brake shoe, it may be detachably attached to allow for replacement in case of wear or damage. Alternatively, the brake pad may be permanently attached to the brake shoe, or only detachable with damage, for example, by a material bond, or it may be integrated into the brake shoe.
[0024] The brake shoe is guided on the brake device housing, specifically between the upper braking position and a lower release position, meaning it is only movable in the direction between the upper braking position and the lower release position and is fixed in other spatial directions. The upper braking position and the lower release position are defined on a vertical direction of the brake device, to which the inclined surfaces have only a small angle and which is perpendicular to the first transverse direction.
[0025] Insofar as the linear roller bearing is arranged between the inclined surfaces, it is positioned between the roller plates and, in particular, in direct contact with them. The linear roller bearing has a shorter length than the roller plates, especially in the direction of the inclined surfaces, so that its rollers can roll without slippage and thus with minimal wear when the brake shoe is moved from the upper braking position to the lower release position. A linear roller bearing can include various types of rollers, including particularly thin rollers, which can be described as needle rollers. TKE2401P-DEWO - 6 - February 2026
[0026] The term "roller" is understood to refer to rollers. A roller can have a cylindrical geometry or deviations from such a geometry, with the rolling plates being shaped accordingly in the case of a deviation from a cylindrical shape. A deviation is, for example, a concave or convex shape of the rollers. A linear roller bearing has at least one roller, but preferably at least two rollers.
[0027] The vertical and transverse directions refer to the braking device itself and can correspond to the arrangement of the braking device, in particular the usual arrangement of the braking device in a space, in which case the vertical direction is the vertical direction. However, the braking device can also be arranged differently in a space, in which case, for example, the vertical direction of the braking device is oriented horizontally in the space, such as in the case of a linearly driven elevator car that is moved between several guide rails of different orientations.
[0028] A roller plate has a surface designed for rolling on a roller of a roller bearing, which exhibits particularly favorable properties with regard to flatness and hardness. In particular, the surface designed for rolling on a roller of a roller bearing is also uninterrupted.
[0029] The solution to the problem with the aforementioned braking device comprises the teaching that a linear roller bearing is arranged between the brake shoe and the brake device housing, over which the first and second ramps roll against each other. By arranging and holding roller plates on the ramps, a particularly low resistance of the brake shoe is achieved when the ramps slide or roll against each other. The roller plates can be designed for low rolling resistance independently of the design of the brake shoe or the brake device housing, for example, through material selection, surface finish, and geometric design. Laterally, the roller plates...The linear roller bearing is provided with a retaining element such that the linear roller bearing is trapped between the roller plates, allowing it to move freely between the roller plates with particularly low resistance. The inclusion of this retaining element results in a structurally simple arrangement that can therefore be manufactured cost-effectively. TKE2401P-DEWO - 7 - February 2026.
[0030] When the brake device is pressed against a braking surface during downward travel (especially downward travel in a vertically moving car), the brake shoe is moved into the upper braking position by the frictional force on the braking surface and also by the spring force of the spring element. It is then held there by the inclined surfaces in such a way that braking occurs. However, when the car moves upward (especially upward travel in a vertically moving car), the frictional force between the brake pad and the braking surface pushes the brake shoe downwards against the spring force, thus bringing it into its release position. The brake pad is then spaced away from the braking surface and cannot be pressed against it to generate a braking force.The arrangement between the brake shoe and the brake device housing according to the present disclosure allows the brake shoe to be moved with particularly low resistance between the upper braking position and the lower release position, so that braking during an upward movement of the car is reliably avoided and it is also reliably achieved that the brake shoe can always be easily and safely returned to the upper braking position by the spring element when it has been moved downwards.
[0031] Alternatively or additionally, the brake shoe can be guided on a guide rod held to the brake device housing, with the spring element being mounted on the guide rod. The brake shoe is thus guided simply and securely between the upper braking position and the lower release position, and the spring element can also be mounted simply and securely on the guide rod. In particular, the spring element is designed as a helical torsion spring and surrounds the guide rod.
[0032] Alternatively or additionally, the roller plates can be made of hardened steel. This allows for a particularly low rolling resistance between the respective roller plate and the roller of the linear roller bearing, especially with low wear, and thus ensures permanently smooth operation.
[0033] Alternatively or additionally, it may be provided that the roller plates are positively and / or materially connected to the brake shoe and the brake device housing. The roller plates are then, in particular, at least in the TKE2401P-DEWO - 8 - February 2026
[0034] The rolling direction is held firmly on the brake shoe or the brake device housing and can be arranged without play relative to the rollers.
[0035] Alternatively or additionally, the first and second ramps can be designed to have an angle of less than 5° relative to the vertical direction of the brake device. The force component resulting from friction between the brake pad and the braking surface parallel to the ramps is then particularly high, or conversely, the force component acting perpendicular to the ramps is particularly low, so that the brake shoe can be moved particularly easily relative to the brake device housing, even under force in the first transverse direction.
[0036] Alternatively or additionally, the linear roller bearing can be positioned relative to the retaining element in the second transverse direction. The linear roller bearing is thus positively locked against movement by the retaining element in at least one spatial direction and can therefore roll smoothly along the roller plates or along the inclined surfaces.
[0037] Alternatively or additionally, the retaining element can be screwed to the brake device housing. The retaining element is then held securely and can be easily loosened, for example for maintenance or component replacement, to provide access to the linear roller bearing.
[0038] Alternatively or additionally, the linear roller bearing can be provided in the second transverse direction on both sides of the brake device housing by a retaining element held to the brake device housing. The brake device housing and the brake shoe can then be free of retaining means for the linear roller bearing, with the linear roller bearing being held and, in particular, positioned in a simple and secure manner by the retaining elements.
[0039] Alternatively or additionally, the brake pad can be positively engaged with the brake shoe. The brake pad is then securely held in place by the brake shoe to transmit braking forces between the braking device, the braking surface, and the passenger car. TKE2401P-DEWO - 9 - February 2026
[0040] Alternatively or additionally, the brake pad can be screwed to the brake shoe. This ensures that the brake pad is held securely to the brake shoe and can be replaced very easily, for example, when the brake pad is worn or damaged, or at regular intervals.
[0041] The problem is further solved by a car for an elevator system, comprising at least one of the braking devices described above. The car essentially achieves the advantages described above with regard to the braking device. In particular, when the braking device is triggered during downward travel, the car is safely braked according to the arrangement of the braking device on the car. Similarly, when the braking device is triggered during upward travel, the brake shoe is safely moved to the lower release position according to the arrangement of the braking device on the car, so that the car is not impeded in its movement. Furthermore, after being moved to the lower release position, the brake shoe reliably returns to the upper braking position once the corresponding force is removed.
[0042] The problem is further solved by an elevator system comprising an elevator shaft and a car movable within the elevator shaft, wherein the car has at least one braking device as described above for decelerating the car relative to a stationary element of the elevator system within the elevator shaft. The elevator system essentially achieves the advantages described above with respect to the braking device and the car, respectively. In particular, when the braking device is triggered during travel in the downward direction, the car of the elevator system is safely braked according to the arrangement of the braking device on the car, while when the braking device is triggered during travel in the upward direction, the brake shoe is safely moved into the lower release position according to the arrangement of the braking device on the car, so that the car is not prevented from moving.Furthermore, after being moved into the lower release position, the brake shoe reliably returns to the upper braking position once the corresponding force is removed. Specifically, braking occurs against a braking surface formed on a guide rail of the car, whereby the brake pad is pressed horizontally against the braking surface. TKE2401P-DEWO - 10 - February 2026.
[0043] Alternatively or additionally, a primary part of a linear drive can extend along the elevator shaft, the elevator car having a secondary part of the linear drive, and a linear drive formed from the primary and secondary parts being designed to drive the elevator car. A linear drive for an elevator system is formed, in particular, from a primary part extending along the elevator shaft and a secondary part located on the elevator car. The primary part is formed from coils arranged in a line, each of which is associated with a converter. An energizer is applied to the coil to generate a magnetic field when the elevator car is in the vicinity of the respective coil. The magnetic field is generated in such a way that the elevator car is attracted or repelled by the magnetic field according to its intended travel path.The secondary part is formed by a permanent or electromagnet that interacts with the magnetic fields of the coil.
[0044] Regarding a car with a linear drive, a braking device with smooth transitions between the upper braking position and the lower release position is particularly important because, in the event of a linear drive failure, the car is held solely by the brake and is significantly heavier than a car with a load-bearing drive. Therefore, the braking forces acting on the car are comparatively high, and the brake shoe must reliably switch between positions even under these high braking forces. Consequently, the brake shoe must not be impeded in either position by the high braking forces. In particular, elevator systems with linear drives allow for upward car evacuation after braking, in which case the braking device easily releases the car for upward movement.
[0045] Brief description of the drawings
[0046] A preferred technical solution is explained in more detail below with reference to the accompanying drawings and preferred embodiments. The term "figure" is abbreviated as "Fig." in the drawings.

[0051] Fig. 2b shows another perspective view of the braking device according to Figure 2a.
[0052] Detailed description of the drawings
[0053] The described embodiments are merely examples that can be modified and / or supplemented in various ways within the scope of the claims. Each feature described for a particular embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a particular claim category can also be used accordingly in an embodiment of a different claim category.
[0054] Figures 1a and 1b show an elevator system 1 (Figure 1a in its entirety in a front view and Figure 1b in a partial side view) in an exemplary embodiment with an elevator shaft 2 extending in a vertical direction V. Vertical guide rails 3.1, 3.2 and horizontal guide rails 3.3, 3.4, 3.5, each with a primary part of a linear drive (not shown) running parallel to them, are arranged on a first wall 2.1 of the elevator shaft 2. The guide rails 3.1, 3.2, 3.3, 3.4, 3.5 thus form tracks for the elevator cars 5.1, 5.2, 5.3, whereby such tracks can also extend through vertical, horizontal, and / or diagonal shaft sections. The carriages 5.1, 5.2, 5.3 are guided, for example, by means of guide rollers on the guide rails 3.1, 3.2, 3.3, 3.4, 3.5, wherein the guide rails 3.1, 3.2, 3.3, 3.4, 3.5 each have a braking surface not shown in detail.
[0055] The elevator cars 5.1, 5.2, 5.3 are each equipped with a carriage 6 and an elevator car cabin 7 mounted thereon (shown in more detail in Figure 1b) and have elevator car doors 8 facing a second wall 2.2 of the elevator shaft 2, in order to connect with TKE2401P-DEWO - 12 - February 2026
[0056] The shaft doors 9.1, 9.2, 9.3, 9.4 provide access to the respective car cabin 7. The cars 5.1, 5.2, 5.3 can travel on all guide rails 3.1, 3.2, 3.3, 3.4, 3.5 and, in particular, can be transferred between vertical guide rails 3.1, 3.2 and horizontal guide rails 3.3, 3.4, 3.5 by means of transfer units 10, whereby the carriage 6 of a car 5.1, 5.2, 5.3 is then positioned opposite the
[0057] The car cabin 7 is rotated so that the car cabin 7 remains upright. In particular, the cars 5.1, 5.2, 5.3 can move in a continuous loop on the guide rails 3.1, 3.2, 3.3, 3.4, 3.5.
[0058] A braking device 13 is arranged on each elevator car 5.1, 5.2, 5.3 or the respective carriage 6, which can secure the elevator car 5.1, 5.2, 5.3 relative to the braking surface of the guide rail 3.1, 3.2, 3.3, 3.4, 3.5 (not shown in detail). Such a braking device 13 can also be arranged on the frame of an elevator car held by a suspension element – the embodiment of an elevator system with a linear drive shown in Figures 1a and 1b is purely exemplary – and is shown in detail in Figures 2a and 2b. Figure 2a shows the braking device 13 in a fully assembled configuration in a perspective view, while in Figure 2b, individual components are hidden to better highlight other components. The braking device 13 has a braking device housing 14, which has an engagement 14.1 for a release mechanism not shown in detail, wherein the release mechanism presses the brake device 13 towards the braking surface in a first transverse direction Q1. A guide rod 15 is held on the brake device housing 14, along which a brake shoe 16 is movably mounted. The brake shoe 16 has a receptacle 16.1 (shown in Fig. 2b) for a brake pad 17 (shown in Fig. 2a), wherein the brake pad 17 has a contact surface 17.1 for flat contact with the braking surface of the guide rails 3.1, 3.2, 3.3, 3.4, 3.5.
[0059] The brake shoe 16 has a first chamfer 19.1 on its side facing the brake device housing 14, while the brake device housing 14 has a second chamfer 19.2 corresponding to the first chamfer 19.1. The brake shoe 16 is thus wedge-shaped and movable on the guide rod 15 in a direction parallel to the chamfers 19.1, 19.2, so that the chamfers 19.1, 19.2 slide against each other. The direction or orientation of the chamfers 19.1, 19.2 is at a slight angle to a vertical direction H of the brake device 13, for example 5° or TKE2401P-DEWO - 13 - February 2026
[0060] less. The brake shoe 16 can thus be moved between an upper braking position, as shown in Figures 2a and 2b, and a lower release position, wherein in the upper braking position the brake pad 17 rests against the braking surface and in the lower release position the brake pad 17 is spaced away from the braking surface. A spring element 20 holds the brake shoe 16 in the upper braking position without external force.
[0061] To allow the brake shoe 16 to slide easily and with low resistance on the brake device housing 14, roller plates 21.2, 21.2 are held on the respective inclined surfaces 19.1, 19.2, in particular by positive locking. The roller plates 21.1, 21.2 are made of hardened steel with a particularly high surface finish and flatness to ensure low rolling resistance. A linear roller bearing 23, comprising a plate-shaped roller cage 23.1 and rollers 23.2 mounted therein, is arranged between the roller plates 21.1, 21.2. When the brake shoe 16 slides between the two positions, the roller plates 21.1, 21.2 roll against each other over the linear roller bearing 23 with particularly low resistance.
[0062] The brake device housing 14 also has bores 25 for attaching a retaining element 26 by means of screws 27. The retaining element 26 covers the linear roller bearing 23 in a second transverse direction Q.2 parallel to the inclined surfaces 19.1, 19.2, thus holding it in position between the roller plates 21.1, 21.2. Furthermore, the retaining element 26 guides the linear roller bearing 23. A further retaining element 26 corresponding to the retaining element 26 can be arranged in the same manner on the rear side of the brake device 13, facing away from the plane of the drawing. Alternatively, the linear roller bearing 23 can be covered there, for example, by a projection of the brake device housing 14. TKE2401P-DEWO - 14 - February 2026
