Description

[0001] The present invention relates to a torsion device for an electromechanical roll stabilization device for a vehicle and a method for manufacturing a torsion device.

[0002] Strain gauges are used, among other things, to make the linear deformation of an element measurable.

[0003] From DE 10 2018 209 782 A1, a torsion device for an electromechanical roll stabilization device for a vehicle is known according to the features of the preamble of claim 1. Four strain gauges are attached to the inner surface of the hollow body serving as a housing for an electric drive device in order to detect a torque acting on the hollow body.

[0004] Reference is also made to the torsion devices previously known from DE 10 2014 208 334 A1, DE 10 2018 110 553 A1, DE 10 2017 104 611 A1 and DE 10 2017 121 863 A1.

[0005] Against this background, the present invention provides an improved torsion device for an electromechanical roll stabilization system for a vehicle and a method for manufacturing an improved torsion device according to the main claims. Advantageous embodiments are described in the dependent claims and the following description.

[0006] The advantages achievable with the presented invention consist in the creation of a torsion device which makes the shear strain of a torsionally rotating torsion body and, additionally or alternatively, an applied torque easily detectable.

[0007] A torsion device for an electromechanical roll stabilization system for a vehicle comprises a torsion body and at least one sensor. The torsion body is designed to be deformable. The sensor is arranged or can be arranged on the torsion body and is configured to detect physical deformation of the torsion body during torsional operation, in order to detect shear strain of the torsion body and, additionally or alternatively, a torque of the vehicle.

[0008] Electromechanical roll stabilization (ERC) works as follows: Active electromechanical roll stabilizers on the front and rear axles of the vehicle generate stabilizing moments during cornering, minimizing or completely eliminating body roll. This also ensures optimal steering and load transfer behavior. When driving straight ahead, an electronic control system adjusts the damping, resulting in a softer, more comfortable suspension response. Body roll is reduced, giving the vehicle high agility and precision across the entire speed range. This electronic actuator can be used in mid-range and luxury vehicles, including those with hybrid or electric powertrains.

[0009] The torsion body can be designed as a housing for the electromechanical roll stabilization device, for example, at least for an ERC controller. The torsion device can then serve to detect shear strain of the torsion body during operation of the electromechanical roll stabilization device, and thus an applied torque of the vehicle, in order to enable, for example, correct control of the electromechanical roll stabilization device for stabilizing the vehicle. The torsion body itself can therefore be referred to as a "primary sensor" and the sensor as a "secondary sensor".

[0010] The sensor can be arranged, directly or indirectly, on an inner wall section or an outer wall section of the torsion body, and in particular, the sensor can be configured as a strain gauge, magnetostrictive element, acoustic sensor, and additionally or alternatively as an optical sensor. The inner and outer walls can be opposing walls of the torsion body, for example, a corrugated or sleeve-shaped torsion body. As a strain gauge, the sensor can be configured to indicate the deformation or shear strain of the torsion body during torsional operation of the torsion device, thus making the torque detectable using the deformation or shear strain. As an acoustic sensor, the sensor can include at least one surface acoustic wave (SAW) filter, which can also be referred to as a "SAW" element.

[0011] The torsion body can be corrugated and, additionally or alternatively, hollow and, additionally or alternatively, have at least one disc-shaped section. The disc-shaped section can extend perpendicularly from the torsion body to a torsion axis or within the torsion body, for example, in the form of a membrane. The sensor can be arranged or arranged in a cavity of the torsion body, for example, on an inner wall section of a hollow, corrugated torsion body facing the cavity. The sensor can be protected within the cavity. Alternatively, the sensor can also be arranged on an outer wall of the corrugated or hollow torsion body. The sensor can also be arranged on the disc-shaped section that extends from the inner or outer wall section.

[0012] According to the invention, the torsion device comprises a sensor receiving device coupled or connectable to the torsion body for receiving the sensor on at least one sensor receiving section of the sensor receiving device. In the operational state, the sensor receiving section can be arranged between the torsion body and the sensor. The sensor receiving device can be coupled or connectable within the cavity of the torsion body or externally to the torsion body. The sensor receiving device can further comprise one or two opposing external force application rings by means of which the sensor receiving device is coupled or connectable to the torsion body. During torsion operation, the torque can be introduced to the sensor receiving section and into the sensor contacted with the sensor receiving section via the force application rings.

[0013] According to one embodiment, the sensor receiving section can be arranged without contact with the torsion body if the sensor receiving device is coupled to the torsion body. Alternatively, the sensor receiving section can be in direct contact with the torsion body via the force application rings of the sensor receiving device, whereby the sensor receiving section, for example as a flat surface, can be arranged to "float" above the torsion body in a bridge-like manner. The sensor receiving section can be formed integrally with the force application ring(s), for example from sheet metal. Friction between the torsion body and the sensor receiving section / sensor can thus be avoided during torsion operation.

[0014] The sensor mounting section can be arranged in a strut-like manner on the torsion body if the sensor mounting device is coupled to the torsion body. In this case, the strut-like sensor mounting section can be arranged obliquely to a longitudinal axis of the torsion body. This allows the sensor to be mounted obliquely to the longitudinal axis.

[0015] According to one embodiment, the sensor receiving unit can have a plurality of sensor receiving sections arranged in a zigzag pattern relative to each other. This can create a framework of compression and tension struts, which can, for example, be arranged circumferentially along the inner or outer wall of the wave-shaped torsion body.

[0016] According to the invention, the sensor mounting section, according to one embodiment, has at least one stiffening element for stiffening the sensor mounting section. The stiffening element prevents deformation of the sensor mounting section and, additionally or alternatively, the sensor itself in at least one direction during torsional operation, for example, lateral stretching / compression. The sensor can thus, for example, detect only axial stretching / compression of the sensor mounting section.

[0017] The sensor receiving device can further comprise at least one shear cell, in particular wherein the sensor receiving section can be directly coupled or couplingable to the torsion body as a shear cell base. The shear cell base can be formed in the form of a membrane. Such a shear cell also provides a suitable receiving option for a sensor. The shear cell can be welded to the torsion body by means of one or more welding tabs. The sensor receiving device can also comprise several, for example three, shear cells, each with, for example, one sensor.

[0018] The sensor mounting device can have at least one support beam and additionally or alternatively a support frame shaped to hold the sensor at a distance from the torsion body. The support beam can have a curved connecting surface for attaching it to the corrugated torsion body. The sensor mounting device can also have two support beams, each holding the sensor at opposite ends. Alternatively, the support beam(s) can be formed integrally with the torsion body as a raised section. The support frame can have two support beams with one or two cross-connections between them for supporting the sensor. The support frame can be formed in one piece.

[0019] According to one embodiment, the sensor can be materially bonded to the torsion body, in particular by welding, soldering, gluing, and additionally or alternatively by bonding. Additionally or alternatively, the sensor can be positively connected and additionally or alternatively frictionally connected to the torsion body, for example, by screwing or clamping. In this case, the sensor can be directly connected to the torsion body. However, the sensor can also be indirectly connected to the torsion body, i.e., via an intermediary element, for example, via the sensor mounting section, which can be connected to the sensor in one of the ways described above. The sensor can be connected to the torsion body or the sensor mounting section by force shunt.

[0020] A method for manufacturing a torsion device for an electromechanical roll stabilization system for a vehicle comprises a provisioning step and an assembly step. In the provisioning step, a deformable torsion body and a sensor are provided. The sensor is configured to detect physical deformation of the torsion body during torsional operation, thereby indicating shear strain and, additionally or alternatively, torque. In the assembly step, the sensor is positioned on the torsion body to manufacture the torsion device. A sensor receiving device, coupled or connectable to the torsion body, serves to receive the sensor on at least one sensor receiving section of the sensor receiving device, and the sensor receiving section includes at least one stiffening element for stiffening the sensor receiving section.

[0021] This process can be implemented, for example, in software or hardware, or in a hybrid form of software and hardware, for example in a control unit.

[0022] The invention presented here further provides a device configured to carry out, control, and implement the steps of a variant of the method presented here in appropriate facilities. This embodiment of the invention, in the form of a device, also allows the underlying problem to be solved quickly and efficiently.

[0023] A device can be an electrical device that processes electrical signals, such as sensor signals, and outputs control signals accordingly. The device can have one or more suitable interfaces, which can be implemented in hardware and / or software. In the case of a hardware implementation, the interfaces can, for example, be part of an integrated circuit in which the device's functions are implemented. The interfaces can also be separate integrated circuits or consist at least partially of discrete components. In the case of a software implementation, the interfaces can be software modules that are present, for example, on a microcontroller alongside other software modules.

[0024] It is also advantageous to have a computer program product with program code that can be stored on a machine-readable medium such as semiconductor memory, hard disk memory or optical memory and is used to carry out the method according to one of the embodiments described above when the program is executed on a computer or device.

[0026] In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and having a similar effect, without repeating these elements.

[0027] Fig. Figure 1 shows a schematic representation of a vehicle 100 with an electromechanical roll stabilization device 105 with a torsion device 110 according to an exemplary embodiment.

[0028] The torsion device 110 is shown, by way of example, attached to the electromechanical roll stabilization device 105, which is also shown, by way of example, attached to the vehicle 100 according to this embodiment. The electromechanical roll stabilization device 105 is in Fig. Figure 12 is shown in more detail. According to an alternative embodiment, the torsion device 110 can be used with a different device that detects and / or generates a torque.

[0029] The electromechanical roll stabilization device 105 is designed to perform electromechanical roll stabilization, or "ERC" (Electromechanical Roll Control), for the vehicle 100. According to one embodiment, this works as follows: Active electromechanical roll stabilizers on a front and / or rear axle of the vehicle 100 generate stabilizing moments during cornering, thus minimizing or completely eliminating body roll. Additionally, according to one embodiment, optimal steering and load transfer behavior is achieved. During straight-line driving, on the other hand, according to one embodiment, an electronic control system adjusts the damping level, ensuring a softer, more comfortable suspension response.According to one embodiment, the copying motion of the superstructure is reduced, thereby giving the vehicle 100 high agility and accuracy across the entire speed range. In this embodiment, the vehicle 100 is a mid-range or upper-range vehicle with any type of drive system, in this case a hybrid or electric drive.

[0030] The torsion device 110 comprises a torsion body 115 and at least one sensor 120. The torsion body 115 is designed to be deformable. The sensor 120 is arranged or can be arranged on the torsion body 115 and is configured to detect a physical deformation of the torsion body 115 during torsional operation, in order to detect a shear strain of the torsion body 115 and / or a torque.

[0031] According to this embodiment, the torsion device 110 is shown in an operational state in which the sensor 120 is arranged on the torsion body 115. According to this embodiment, the torsion body 115 is hollow and wave-shaped. The sensor 120 is arranged in a cavity 125 of the hollow, wave-shaped torsion body 115. In this embodiment, the sensor 120 is mounted on an inner wall section of an inner wall 130 of the torsion body 115 facing the cavity 125. According to an alternative embodiment, the sensor 120 is arranged on an outer wall section of an outer wall 135 of the torsion body 115 opposite the inner wall 130, and / or the torsion body 115 is wave-shaped without a cavity 125.

[0032] According to this embodiment, the sensor 120 is arranged directly, i.e., immediately, on the inner wall section. Furthermore, according to this embodiment, the sensor 120 is a strain gauge, a magnetostrictive element, an acoustic and / or optical sensor. The strain gauge is designed to indicate the deformation or shear strain of the torsion body 115 during torsional operation of the torsion device 110, in order to make the torque of the vehicle 100 detectable using the deformation or shear strain.

[0033] According to this embodiment, the sensor 120 is materially bonded to the torsion body 115, welded, soldered, glued, and / or bonded according to different embodiments. Additionally or alternatively, according to one embodiment, the sensor 120 is positively and / or force-fitted to the torsion body 115, screwed and / or clamped to the torsion body 115 according to another embodiment, and / or connected to the torsion body 115 by a force shunt. According to this embodiment, the sensor 120 is rectangular, for example, square, with rounded corners, tab-like, and / or with smooth surfaces.

[0034] For force and torque measurement, a deformation body, such as a Hookean solid, is generally required, whose (linear) deformation is suitablely converted into an electrical signal. Various methods are known to experts for this purpose. One of the challenges is reliably connecting the strain gauge to the deformation body mechanically in an industrial manufacturing environment. While technically possible, this is a complex procedure, usually requiring expert manual work. This is particularly challenging with large, small, or difficult-to-access deformation bodies, as it demands meticulous attention to detail.

[0035] For strain measurement alone, tabs exist that are attached to the deformation body via a force shunt and measure its strain. These tabs are manufactured in the laboratory or in an environment similar to semiconductor technology. They can therefore be produced very economically and reliably. The torsion device 110 presented here, using the sensor 120, which in one embodiment is such a tab, advantageously enables shear strain and torque measurement. In other words, the invention presented here generalizes a principle of strain measurement with sensor tabs in a force shunt to shear strain and torsion (torque) measurement. Further specific design variants of the torsion device 110, which can also be referred to as a "torsion measuring tab," are presented in the following figures.

[0036] The torsion device 110 solves the problem described above of shear strain and torque measurement in a force shunt. According to one embodiment, the sensor 120, in the form of a tab, is connected to the torsion body 115, in the form of a Hookean deformation body, by gluing, welding (the various known methods), soldering, clamping, screwing, bonding and / or similar technologies, similar to a tab for uniaxial strain.

[0037] The sensor 120 can employ any of the principles known to those skilled in the art for measuring mechanical strain and shear strain. These include, in particular, strain gauges, magnetostriction, SAW elements, and acoustic and optical principles. A significant design freedom of the invention presented here is the ability to select the sensor 120 in terms of material and shape independently of the deformation body and / or to bring it into direct mechanical contact with the strain-to-electrical transducer element. This also allows for optimization of the measurement task and / or the conversion of the mechanical strain into an electrically measurable quantity. A conflict of objectives that otherwise regularly occurs for the torsion body 115 when measuring directly on it can be resolved. All figures shown in Fig. Points 1 to 11 can also be applied analogously to the mounting on shafts, for example on the outside, as well as to membranes / discs mounted perpendicular to the axis of torsion.

[0038] The torsion device 110 presented here offers a solution for the above-described problem of shear strain and torque measurement in force shunt with tabs that can be manufactured in series production according to automotive standards.

[0039] According to this embodiment, the sensor 120 is applied directly to the deformation body 115. The connection is made by gluing, soldering, welding, bonding, etc., which advantageously creates a durable, creep-free connection.

[0040] Fig. Figure 2 shows a perspective view of a torsion device 110 according to an exemplary embodiment. This could be the one described in Fig. 1 described torsion device 110, with the difference that the torsion device 110 has a sensor receiving device 200 for receiving the sensor 120.

[0041] According to this embodiment, the sensor receiving device 200 is coupled to the torsion body 115 in its operational state and has at least one sensor receiving section 205 that receives the sensor 120. In its operational state, the sensor receiving section 205 is arranged between the torsion body 115 and the sensor 120. According to this embodiment, the sensor receiving device 200 is coupled within the cavity of the torsion body 115, or, according to an alternative embodiment, externally to the torsion body 115. According to this embodiment, the sensor receiving device 200 has one or two opposing external force application rings 210 by means of which the sensor receiving device 200 is coupled to the torsion body 115.

[0042] In this embodiment, the sensor mounting section 205 itself is arranged without contact with the torsion body 115 and / or is only contacted with the torsion body 115 via the force application rings 210 of the sensor mounting device 200, wherein the sensor mounting section 205, here formed as a flat surface, is arranged to "float" above the torsion body 115. In this embodiment, the sensor mounting section 205 is formed integrally with the two force application rings 210, for example, from sheet metal. In this embodiment, the sensor mounting section 205 is arranged on the torsion body 115 in a strut-like manner. Here, the strut-like sensor mounting section 205 is arranged at an angle to a longitudinal axis of the torsion body 115. The sensor 120, which is mounted directly on the sensor mounting section 205, is also arranged at an angle to the longitudinal axis in this embodiment.According to this embodiment, the sensor receiving section 205 further comprises at least one stiffening element 215 for stiffening the sensor receiving section 205.

[0043] According to this embodiment, the sensor mounting unit 200 has a plurality of sensor mounting sections 205 arranged in a zigzag pattern relative to one another. This creates a framework of compression and tension struts, which, according to this embodiment, are arranged circumferentially along the inner wall 130 of the corrugated torsion body 115. The force application rings 210 are also contacted circumferentially on the inner wall 130, according to this embodiment. Each of the sensor mounting sections 205 has two stiffening elements 215, each arranged at opposite edges of the sensor mounting section 205. According to this embodiment, the stiffening elements 215 prevent lateral expansion / compression of the sensor mounting section 205 and / or sensor 120 during torsional operation, while allowing axial expansion / compression of the sensor mounting section 205 and / or sensor 120.

[0044] According to this embodiment, the sensor 120 is therefore not directly, but indirectly connected to the torsion body 115, here via the sensor receiving section 205, which according to this embodiment is connected to the sensor 120 by material connection, force connection and / or form connection and / or by force shunt connection to the sensor receiving section 205.

[0045] In Fig. Figure 2 shows a variant of the torsion device 110 with a framework of tension and compression rods made of formed sheet metal. The (Hookian) torsion body 115 reacts linearly to an externally applied axial torque by means of a torsional deformation. This deformation is introduced via the force introduction rings 210 as tensile / compressive stress / strain into the sensor receiving sections 205 in the form of tension and compression struts. These do not touch the torsion body 115, but rather "float" minimally above it to avoid friction at this point. According to this embodiment, the tension and compression struts are stiffened by suitable design measures, for example, by the stiffening elements 215 in the form of stiffening cheeks. The actual measuring elements, i.e., the sensors 120, are intimately connected to the tension and compression struts and measure their axial strain or compression.The overall behavior allows conclusions to be drawn about torsion and other acting loads. How this is done is familiar to the technical expert.

[0046] Fig. Figure 3 shows a perspective view of a section of a torsion device 110 according to an exemplary embodiment. This is the one described in Fig. 2 described torsion device 110 with the cutout in close-up view. Fig. Figure 4 shows a schematic representation of a section of a torsion device 110 according to an exemplary embodiment. This can be the one described in Fig. The section shown in section 3 is a cross-sectional view along the longitudinal axis of the torsion body 115. Fig. 4 The force introduction rings 210 in one possible design, as well as the stiffening elements 215 in the form of the stiffening cheeks, can be clearly seen.

[0047] Fig. Figure 5 shows a schematic representation of a section of a torsion device 110 according to an exemplary embodiment. This can be the one described in Fig. The section shown in section 4 is a cross-sectional view along one of the sensor recording sections 205 in the form of a compression / tension strut. Fig. Figure 5 makes it clear that the strut does not touch the hollow shaft as a deformable torsional body 115, or only touches it at the force introduction rings 210.

[0048] Fig. Figure 6 shows a perspective view of a torsion device 110 according to an exemplary embodiment. This can be the one described in one of the Fig. The torsion device 110 described in sections 2 to 5 is shown in [reference to relevant section]. Fig. 6 A representation of the strains on the tension and compression struts of the sensor.

[0049] Fig. Figure 7 shows a perspective view of a torsion device 110 according to an exemplary embodiment. This can be the one described in one of the Fig. The torsion device 110 described in sections 2 to 6 is involved, with the difference that the sensor receiving device 200 has at least one shear cell 700.

[0050] In this embodiment, the sensor mounting section 205 is directly contacted on the torsion body 115 as a shear cell base of the shear cell 700. The sensor mounting section 205 is shaped as a curved membrane. A connection between the shear cell 700 and the torsion body 115 is established by means of welded tabs 705. In this embodiment, three shear cells 700 are, by way of example, attached to the inner wall at uniform intervals. Such an arrangement with more than one measuring element is advantageous in torsion operation for the compensation of parasitic loads. In an alternative embodiment, the shear cell 700 is not part of the sensor mounting device 200, but rather the sensor 120 itself.

[0051] Fig. Figure 8 shows a perspective view of a section of a torsion device 110 according to an exemplary embodiment. This can be the one described in one of the Fig. 2 to 6 or those in Fig. The torsion device 110 described in Section 7 differs from the sensor receiving device 200, with the difference that the sensor receiving device 200 has at least one support frame 800, which is shaped to receive the sensor 120 at a distance from the torsion body 115. According to this embodiment, the support frame 800 has two support webs 805 extending parallel to each other and perpendicularly away from the torsion body 115, each of which has a curved connecting surface for joining to the inner wall of the corrugated torsion body 115. The support frame 800 has one or two transverse connections 810 between the support webs 805 for supporting the sensor 120. According to this embodiment, the support frame 800 is formed in one piece. The sensor 120 is arranged in a force shunt and / or resting flush on the transverse connections 810. Sensor 120 is shown broken here for better visibility.

[0052] Fig. Figure 9 shows a perspective view of a torsion device 110 according to an exemplary embodiment. This could be the one described in Fig. The torsion device 110 described in section 8 is the same, with the difference that the sensor receiving device 200 only has the two support webs 805 without cross connection(s).

[0053] In this embodiment, two opposing sensor ends of the sensor 120 are each received on one edge of the two support webs 805 opposite the curved connecting surface. The torsion device 110 according to this embodiment is shown with separately mounted and / or connected support webs 805 on the torsion deformation body and a flat sensor 120 in force shunt configuration.

[0054] Fig. Figure 10 shows a perspective view of a section of a torsion device 110 according to an exemplary embodiment. This can be the one described in Fig. The torsion device 110 described in Figure 9 differs in that, according to this embodiment, the support webs are formed integrally with the torsion body 115 as projections. In this embodiment, the support webs can also be described as disc-shaped sections 1000, which, according to this embodiment, extend perpendicularly to a torsion axis within the torsion body 115, here in the form of a membrane of the torsion body 115. According to an alternative embodiment, the disc-shaped sections 1000 extend perpendicularly to a torsion axis from the outer wall of the torsion body 115. The torsion device 110 according to this embodiment is shown with formed support webs in the form of disc-shaped sections 1000 on the torsion body 115 and a flat sensor 120 in force shunt. The sensor 120 is shown broken here for better visibility.

[0055] Fig. Figure 11 shows a perspective view of a section of a torsion device 110 according to an exemplary embodiment. This is a sectional view of the Fig. 10 described support beams / disc-shaped sections 1000 of the torsion device 110.

[0056] Fig. Figure 12 shows a schematic cross-sectional view of an electromechanical roll stabilization device 105 with a torsion device 110 according to an exemplary embodiment. This could be the one described in Fig. The electromechanical roll stabilization device 105 described in Figure 1 can be combined with one of the torsion devices 110 described in one of the preceding figures. The vehicle 100 can also be equipped with the device described in Figure 1. Fig. 1 described vehicle 100.

[0057] The purely schematic representation shows a section through the vehicle 100 along its vertical and transverse axes. Shown, for example, is a first axle 1200 with an embodiment of the roll stabilization device 105, also referred to as a stabilizer. The roll stabilization device 105 is implemented as a two-part torsion bar with a first stabilizer element 1205 and a second stabilizer element 1210. One end of the first stabilizer element 1205 is connected to a first wheel suspension element 1215 of the vehicle 100, and one end of the second stabilizer element 1210 is connected to a second wheel suspension element 1220 of the vehicle 100.

[0058] For example, the ends of the stabilizer elements 1205, 1210 are designed as arms, preferably bent or cranked approximately in the direction of travel, which are connected to the wheel suspension elements 1215, 1220 by means of articulated pendulum supports 1225, 1230. The wheel suspension elements 1215, 1220 are, for example, opposing control arms of the vehicle 100. The stabilizer elements 1205, 1210 are each rotatably attached to a chassis or the body of the vehicle 100 by means of a mounting bearing 1235 about a common axis of rotation DD. The axis of rotation DD corresponds, for example, to the transverse axis of the vehicle 100.

[0059] Each end of the stabilizer elements 1205, 1210, facing the center of the vehicle 100, is mechanically coupled to at least one electric motor of a three-phase drive unit 1240, which serves as an actuator. The three-phase drive unit 1240 is designed to rotate the stabilizer elements 1205, 1210 in opposite directions about the axis of rotation DD using a control signal 1245 from a control device 1250. The control signal 1245 represents, for example, a signal determined based on field-oriented control. By rotating the stabilizer elements 1205, 1210 in opposite directions, the wheel suspension elements 1215, 1220 are moved, thus counteracting body roll, for example, when cornering. According to one embodiment, the vehicle 100 is equipped with the control device 1250, which is connected to the three-phase drive unit 1240 and is designed to provide the control signal 1245.

[0060] The vehicle 100 can also have a second electromechanical roll stabilization device, which can be designed accordingly to the roll stabilization device 105. Alternatively, an alternative roll stabilization principle can be used. For example, the stabilizer elements 1205, 1210 can be omitted if the counter-rolling moments are provided, for example, by suitable actuators in the wheel suspension elements 1215, 1220.
