Description

Technical Field

[0001] The present invention relates to a rocker arm for a current collector in a vehicle, the rocker arm having at least one first contact piece and a second control lever device, the at least one first contact piece being connected to the first control lever device, the first control lever device being coupled to a first support device, and the second control lever device being coupled to a second support device, wherein the first support device and the second support device are hingedly connected to a current collector linkage mechanism. Background Technology

[0002] Electric vehicles are typically equipped with current collectors (such as pantographs or scissor pantographs, etc.) that collect current from contact wires or conductive rails, etc., and that power is supplied to the vehicle's electric drive unit by means of the current collectors.

[0003] Strong forces act on the current collector, especially when the vehicle is traveling at high speed. These forces are partly the contact forces between the contact plates of the current collector's rocker arm and the contact wire or conductive rail, etc., and partly the aerodynamic forces generated by dynamic forces.

[0004] Therefore, it is important to provide an effective spring for the rocker arm that makes contact with the contact wire or conductive rail via one or more contact pieces, so as to reduce the load on the current collector linkage and avoid contact loss between the current collector and the contact wire or conductive rail, etc.

[0005] An example known from the prior art is EP 2 644 433 A2, which discloses a current collector with a current collector linkage mechanism and a tiltable rocker arm that contacts a contact wire via a contact piece. The current collector linkage mechanism includes an upper arm and a lower arm, as well as a pneumatic actuator, which carries the rocker arm and is hinged to a vehicle. The rocker arm can be raised and lowered via the actuator.

[0006] Similarly, WO 02 / 32714 A1 describes a frame rocker arm for a current collector in an electric vehicle, wherein two reinforced frames are hinged to two contact plates. The frames have an extended frame tube in which torsion springs are mounted. The rocker arm is connected to the vertex axis of the current collector via the torsion springs. In this arrangement, a first torsion spring is coupled to a first end of the vertex axis, while a second torsion spring is connected to a second end of the vertex axis. The torsion springs are non-rotatably connected to a carrier element via a support element, which is connected to the vertex axis.

[0007] Furthermore, EP 0 844 131 A1 similarly discloses a frame rocker with contact plates for a current collector in an electric vehicle. The contact plates are rigidly connected to a carrier element via a U-shaped spring yoke (the arms of which extend laterally in the longitudinal direction of the vehicle), the carrier element being connected to the apex axis of the current collector.

[0008] EP 1 361 103 B1 also discloses a rocker arm for a current collector in an electric vehicle, which is connected to the upper arm of the current collector via a control lever device, a shaft, and a spring independent of said shaft. The shaft is mounted in a carrier tube and is supported axially and radially by a support member. Torque is introduced into the shaft via the control lever device, and the spring generates a corresponding reaction torque, wherein said spring is connected to the shaft on one side and to the carrier tube on the other.

[0009] In its known form, the cited method suffers from the following disadvantages: the rocker or contact plate has no significant mobility compared to the linkage mechanism or upper arm or apex axis, and there is almost no compensation for deformation and / or a complex support device including shafts and springs is provided, for example, between the rocker and the upper arm. Summary of the Invention

[0010] The object of this invention is to disclose a rocker arm that represents an advancement over the prior art, is simple in its construction, and also has appropriate load-bearing capacity, including load-bearing capacity with respect to dynamic loads.

[0011] According to the invention, this object is achieved by means of a rocker arm of the type described in the introduction, wherein a first torsion spring is fixedly connected to the control lever of the first control lever device and non-rotatably connected to the first support device via a movable support member, or the first torsion spring is non-rotatably connected to the control lever of the first control lever device and fixedly connected to the first support device via a movable support member, wherein the first torsion spring is simultaneously a torque transmission device and a spring device between the first control lever device and the first support device.

[0012] Therefore, a particularly lightweight, compact, yet robust and wear-resistant device for collecting electric current is realized. The complex support device between the rocker arm and the current collector linkage, such as a shaft enclosed by a helical spring, can be eliminated. The device according to the invention can be implemented using a small number of components, which are also less complex.

[0013] The first torsion spring simultaneously functions as a torque transmission device and a spring device. The contact force transmitted from the contact wire or conductive rail via the first contact piece is introduced into the first torsion spring through the first control lever device. The first torsion spring twists due to the presence of a torsional torque. The corresponding reaction spring force counteracts the effect of the torsional torque due to the stiffness of the corresponding torsion spring. The loading and unloading processes of the first contact piece and the first control lever device are achieved through a spring-loaded buffer, thus realizing a mechanical separation of the rocker arm support.

[0014] The first torsion spring is separated from the forces acting on the rocker arm along the longitudinal and lateral directions of the vehicle.

[0015] The rocker arm support is suitable for loads caused by contact forces and aerodynamic forces, including high-frequency dynamic loads. The movable support provides compensation for, for example, changes in the length of the first torsion spring caused by the torque of the first torsion spring. This has the effect of reducing the load on the rocker arm and preventing damage, especially under heavy loads and / or high-frequency loads.

[0016] Advantageously, the first torsion spring is shape-locked (forced locking, positive locking) and pre-tensioned.

[0017] If the first torsion spring is fixedly connected to the control lever of the first control lever assembly, the assembly and disassembly tasks are simplified. For assembly purposes, the first control lever assembly or the control lever of the first control lever assembly must be simply threaded into the first support device along with the first torsion spring pre-installed thereon and subsequently connected to said support device.

[0018] The suspension characteristics adapted to limited load conditions are achieved by pretensioning the first torsion spring.

[0019] An advantageous embodiment is obtained if the first support device includes a clamping element to which the first torsion spring is connected.

[0020] This measure enables the rocker arm support to be modularized. This allows, for example, the clamping element to be replaced subsequently while maintaining the first support device that can be connected to the current collector linkage mechanism, so that the first torsion spring can be replaced with a different torsion spring (e.g., for wear and tear or due to changes in load conditions).

[0021] Helpfully, the first support device has a first housing, and a first torsion spring is arranged inside the first housing.

[0022] Because of this measure, the first torsion spring is protected from environmental influences (such as humidity and particles).

[0023] To support simple and quick replacement of the clamping element and the first torsion spring, while also protecting the clamping element from environmental influences, it can be further provided that the clamping element is non-rotatably and detachably connected to the first housing and arranged inside the first housing.

[0024] If the first mounting device is non-rotatably connected to the control lever of the first control lever device and rotatably connected to the first housing, the simplicity and quick replaceability of the first torsion spring, which is connected to the first control lever device via the first mounting device, is further improved.

[0025] Therefore, the first mounting device acts as an adapter for the first torsion spring on one hand, and as an adapter for the first control lever device on the other.

[0026] If a second contact piece is provided, an advantageous solution is achieved, wherein the second contact piece is connected to a third control lever device and a fourth control lever device, the third control lever device being coupled to a first support device and the fourth control lever device being coupled to a second support device, wherein a third torsion spring, which is simultaneously a torque transmission device and a spring device between the third control lever device and the first support device, is fixedly connected to the control lever of the third control lever device and non-rotatably connected to the first support device via a movable support member, or is non-rotatably connected to the control lever of the third control lever device via a movable support member and fixedly connected to the first support device.

[0027] In this case, it is advantageous that the third torsion spring is connected to the clamping element.

[0028] Because the first and third torsion springs are separated by the clamping element, they can adapt to the corresponding load conditions acting on the first and second contact plates almost independently. Therefore, the rocker arm according to the invention exhibits a low tendency for overload or damage caused therefrom, and also a low tendency for excessive wear. Attached Figure Description

[0039] The rocker arm is also hinged to the parallel guide rod 6 and engages with the contact line 24 via a first contact piece 13 and a second contact piece 14, which include carbon sliders (not shown) known from the prior art, so that the rail vehicle is supplied with electricity.

[0040] The first contact piece 13 and the second contact piece 14 are parallel to each other. Figure 1 The vehicle's lateral axis 25, which appears to protrude from the center, is aligned. The first support device 18 and the second support device 19 are aligned parallel to the vehicle's longitudinal axis 26, that is, rotated 90° relative to the first contact piece 13 and the second contact piece 14 due to the first control lever device 15, the second control lever device 16, the third control lever device 17, and the fourth control lever device.

[0041] exist Figure 2 The schematic first side view discloses an exemplary first embodiment variation of the joystick according to the present invention.

[0042] The rocker arm is provided as a current collector for rail vehicles (e.g., via...). Figure 1 (as shown in the example), and includes a first contact piece 13 and a second contact piece 14 (as shown in the example). Figure 1 and Figure 3 (as shown in the image).

[0043] The joystick also includes a first control lever device 15, a second control lever device 16, and a third control lever device 17 (shown in...). Figure 3 The joystick includes a first support device 18 and a second support device 19, which are coupled to a first control lever device 15, a second control lever device 16, a third control lever device 17, and a fourth control lever device 30. The first control lever device 15 has a first control lever 27 and a second control lever 28, and the second control lever device 16 has a third control lever 29 and a fourth control lever 30.

[0044] The first control lever 27 is connected to the first contact piece 13 via the first rotary joint 31, and the second control lever 28 is connected to the first control lever 27 via the second rotary joint 32. Furthermore, the second control lever 28 is fixedly connected to the first mounting device 34 by means of a threaded connection (i.e., in a non-movable and non-rotatable manner), and the first mounting device 34 is rotatably connected to the first housing 20 of the first support device 18 (shown in…). Figure 3 middle).

[0045] The third control lever 29 is fixedly connected to the first contact piece 13 by means of a threaded connection, and the fourth control lever 30 is connected to the third control lever 29 via the third rotary joint 33. The fourth control lever 30 is also fixedly connected to the second mounting device 35, which is in turn rotatably connected to the second housing (not shown) of the second support device 19.

[0046] The second contact plate 14 of the current collector is connected via the third control lever device 17 and via the third mounting device 36 (shown in...) Figure 3 (middle) is connected to the first support device 18, and is connected to the second support device 19 via the fourth control lever device and the fourth mounting device (not shown).

[0047] In terms of their arrangement relative to each other and their construction, the second contact piece 14, the third control lever device 17, the fourth control lever device, the third mounting device 36, and the fourth mounting device are implemented in the same manner as the first contact piece 13, the first control lever device 15, the second control lever device 16, the first mounting device 34, and the second mounting device 35, although with respect to the first contact piece 13, the first control lever device 15, the second control lever device 16, the first mounting device 34, and the second mounting device 35, they are connected to the first housing 20 and the second housing, and rotated 180°.

[0048] The first torsion spring 21 is provided inside the first housing 20 and is fixedly connected to the first mounting device 34 by means of a threaded connection, and is thus fixedly connected to the second control lever 28 of the first control lever device 15.

[0049] The second torsion spring 22 is provided inside the second housing and is fixedly connected to the second mounting device 35 by means of a threaded connection, and is thus fixedly connected to the fourth control lever 30 of the second control lever device 16.

[0050] A third torsion spring 23 (shown in) is also arranged in the first housing 20. Figure 3 (in the middle) is attached to the third mounting device 36 by means of a threaded connection, and is thus fixedly connected to the control lever of the third control lever device 17.

[0051] A fourth torsion spring (not shown), also arranged in the second housing, is attached to the fourth mounting device by means of a threaded connection, and is thus fixedly connected to the control lever of the fourth control lever device.

[0052] The first torsion spring 21, the second torsion spring 22, the third torsion spring 23, and the fourth torsion spring have rectangular cross-sections.

[0053] The first torsion spring 21 and the third torsion spring 23 are non-rotatably connected to the first support device 18 via a movable support member, and the second torsion spring 22 and the fourth torsion spring are non-rotatably connected to the second support device 19 via a movable support member. This combination Figure 3 The first torsion spring 21 and the third torsion spring 23 are described by way of example.

[0054] The first torsion spring 21, the second torsion spring 22, the third torsion spring 23, and the fourth torsion spring twist under load due to their fixed and non-rotatable support components.

[0055] The first torsion spring 21, the second torsion spring 22, the third torsion spring 23, and the fourth torsion spring are simultaneously torque transmission devices and spring devices between the first control lever device 15, the second control lever device 16, the third control lever device 17, and the fourth control lever device, and between the first support device 18 and the second support device 19.

[0056] Figure 3 The same is shown in Figure 1 and Figure 2 The diagram shows a schematic variation of the same exemplary first embodiment of the rocker arm of the present invention for a current collector of a rail vehicle. Therefore, in some cases, the same reference numerals are used. A first side view of the rocker arm is shown. Figure 2 compared to, Figure 3 A sectional second side view of the joystick is shown, which reveals the view of the joystick rotated 90° relative to the first side view.

[0057] The rocker arm includes a first contact piece 13, a second contact piece 14, a first control lever device 15, and a second control lever device 16 (shown in...). Figure 2 (in the middle), third control lever device 17, fourth control lever device (not shown), first support device 18 and second support device 19 (shown in ... support lever device (not Figure 2 (in the middle), they are connected to the first mounting device 34 and the second mounting device 35 (shown in the middle), Figure 2 (Middle), third installation device 36 and fourth installation device (not shown).

[0058] The first torsion spring 21 is connected to the first mounting device 34, and the second torsion spring 22 (shown in...) Figure 2 The first torsion spring (23) is connected to the second mounting device 35, the second torsion spring (23) is connected to the third mounting device 36, and the third torsion spring (not shown) is connected to the fourth mounting device.

[0059] The first contact piece 13 is connected to the first mounting device 34 via a first control lever device 15, and the first control lever device 15 and the first mounting device 34 are attached to each other by means of a threaded connection. The first mounting device 34 is rotatably connected to the hollow cylindrical first housing 20 of the first support device 18 via a first roller bearing 37. The first housing 20 is made of fiber-reinforced composite material and acts as a rocker arm box. The first roller bearing 37 is attached to the first housing 20 by means of a threaded connection.

[0060] According to the invention, it is also conceivable that the first housing 20 is made of a metallic material. The first mounting device 34 has a first groove 39 on its front side, and the first end of the first torsion spring 21, made of spring steel, is clamped into place and fixed to the first groove 39 by means of a threaded connection.

[0061] According to the present invention, it is also conceivable, for example, to realize the first torsion spring 21 using fiber-reinforced composite materials.

[0062] The first torsion spring 21 has a rectangular cross-section and is mounted in a second groove 40 of a cylindrical metal clamping element 44 associated with the first support device 18 via its second end in a non-rotatable, shape-locked, and displaceable manner along its longitudinal axis 43 and along the longitudinal extension of the first contact piece 13 (i.e., along the width of the first torsion spring 21), or, if applicable, along a direction transverse to the longitudinal axis 43. The height of the rectangular cross-section of the first torsion spring 21 is smaller than the length of the first torsion spring 21.

[0063] The second groove 40 is milled out on the first front surface of the clamping element 44. The corresponding machining of the clamping element 44 in the region of the second groove 40 enables the first torsion spring 21 to slide into and out of the second groove 40 with minimal resistance.

[0064] The first torsion spring 21 is pre-tensioned after the first mounting device 34 is connected to the first housing 20.

[0065] Therefore, it is possible to reduce the mechanical stress in the first torsion spring 21 (i.e., the mechanical load on the first torsion spring 21). Thus, the first torsion spring 21 experiences a reduced load on the one hand, and on the other hand, it is subjected to the reduced load by the first contact piece 13 and the contact wire 24 (shown in...). Figure 1 The load caused by the contact force between the two sides can be flexibly responded to.

[0066] Clamping element 44 is secured by a fastening device known from the prior art. Figure 3 (Not shown) is connected to the first housing 20, i.e., to the first support device 18, by means of a threaded connection (i.e., detachably). The fastening device is connected to the clamping element 44 via a corresponding notch (also not shown) in the first housing 20.

[0067] Due to the threaded connection that secures the clamping element 44 to the first support device 18 and the non-rotatable, movable installation of the first torsion spring 21 in the clamping element 44, the first torsion spring 21 is connected to the first support device 18 in a non-rotatable and movable manner.

[0068] A third groove 41 is provided on the second front surface of the clamping element 44, through which the third torsion spring 23 is connected to the first support device 18 in a non-rotatable and displaceable manner. The third torsion spring 23 is further connected to the third mounting device 36 by means of a clamping action in a fourth groove 42 provided on the front surface of the third mounting device 36 and by means of a threaded connection. In terms of material, geometry, and connection techniques for attaching to the clamping element 44 and the third mounting device 36, and in terms of orientation, the third torsion spring 23 is implemented in the same manner as the first torsion spring 21.

[0069] The third torsion spring 23 has the same longitudinal axis 43 as the first torsion spring 21.

[0070] The first torsion spring 21, the third torsion spring 23, and the clamping element 44 are arranged inside the first housing 20.

[0071] The longitudinal axis of the first housing 20 and the longitudinal axes 43 of the first torsion spring 21 and the third torsion spring 23 extend into each other.

[0072] According to the present invention, it is also conceivable to omit the third torsion spring 23 and connect the first torsion spring 21 to the first mounting device 34 and the third mounting device 36.

[0073] The third mounting device 36 is rotatably connected to the first housing 20 (i.e., to the first support device 18) via a second roller bearing 38, which, like the first roller bearing 37, is attached to the first housing 20 by means of a threaded connection.

[0074] The third control lever device 17 is attached to the third mounting device 36 by means of a threaded connection.

[0075] The third control lever device 17 is then connected to the second contact piece 14.

[0076] The first housing 20 is attached to the retaining element 45 of the first support device 18 by means of a threaded connection using a fastening device (not shown) known from the prior art.

[0077] The first support device 18 is hinged to the top rod 4 of the current collector via a retaining element 45 (shown in...). Figure 1 The first push rod end of the (middle) is connected to the current collector linkage mechanism 1.

[0078] In terms of its construction, and regarding its connection to the top rod 4, the second support device 19 is implemented in the same manner as the first support device 18. The second support device 19 is hinged to the second top rod end of the top rod 4.

[0079] In terms of its structure and function, the second housing and its contents (including the second torsion spring 22 and the fourth torsion spring) are implemented in the same manner as the first housing 20 and its contents.

[0080] The second housing is arranged and aligned parallel to the first housing 20.

[0081] No reinforcing frame is provided between the first control lever device 15 and the third control lever device 17, or between the second control lever device 16 and the fourth control lever device, etc. The rocker arm according to the invention is implemented as a frameless rocker arm or as a rocker arm with an individually sprung contact strip.

[0083] An exemplary second embodiment variation of the joystick of the present invention is similar to that by... Figure 3 The examples shown are exemplary variations of the first embodiment. Therefore, in some cases, in... Figure 4 Used with Figure 3 The same reference numerals are used in the accompanying drawings.
