Abstract
Description
Technical Field
[0001] This disclosure relates to the field of passenger vehicles, and more specifically, to a lubrication system for a passenger vehicle, a method performed by the lubrication system, and a passenger vehicle including the lubrication system. Background Technology
[0002] Passenger transport vehicles rely on chains to drive the cyclical movement of steps or pedals during operation. The lubrication of the chain directly affects the performance and service life of the vehicle. Current lubrication systems for passenger transport vehicles use fixed oil supply parameter settings. For example, fixed oil supply parameters (such as oil supply volume and the opening duration of the hydraulic valves) are set for different numerical ranges of vertical rise. This coarse setting easily leads to inappropriate lubricant levels. For instance, excessive oil supply at short rises results in resource waste and environmental pollution, while insufficient oil supply at longer rises affects lubrication effectiveness. Summary of the Invention
[0003] One aspect of this disclosure provides a lubrication system for a passenger transport vehicle. The lubrication system includes: an oil reservoir configured to store lubricating oil; a control device configured to determine the amount of lubricating oil required for lubricating the passenger transport vehicle based at least on the number of steps or pedals of the passenger transport vehicle and the dimensions of the chain links of the passenger transport vehicle; and an oil distribution device configured to distribute the determined amount of lubricating oil into a plurality of oil passages, any one of which leads to a chain segment in the chain of the passenger transport vehicle corresponding to that oil passage.
[0004] Another aspect of this disclosure provides a method for use by a lubrication system of a passenger vehicle. The method includes: determining a quantity of lubricating oil required for lubricating the passenger vehicle based at least on the number of steps or pedals of the passenger vehicle and the dimensions of the chain links of the passenger vehicle; and distributing the determined quantity of lubricating oil into a plurality of oil passages, any one of which leads to a chain segment in the chain of the passenger vehicle corresponding to that oil passage.
[0005] Another aspect of this disclosure provides a manned transport vehicle that includes the lubrication system as described above.
[0006] Compared to setting the lubricant supply amount using fixed oil supply parameters, this disclosure determines the lubricant supply amount based on the number of steps or pedals of the passenger vehicle and the chain link size of the passenger vehicle, so that the determined supply amount is more matched with the specifications of the passenger vehicle, thereby improving the lubrication condition of the passenger vehicle, increasing the performance and service life of the passenger vehicle. Attached Figure Description
[0007] The aspects, features, and advantages of this disclosure will become clearer and more readily understood from the following description of embodiments of this disclosure in conjunction with the accompanying drawings, wherein:
[0008] Figure 1 A schematic diagram of a manned transportation vehicle is shown.

[0014] Figure 7 A flowchart illustrating a method performed by a lubrication system according to at least one embodiment of the present disclosure is shown. Detailed Implementation
[0015] The present disclosure will now be described in detail with reference to exemplary embodiments thereof. However, the present disclosure is not limited to the embodiments described herein, which may be implemented in many different forms. The described embodiments are provided only to make the present disclosure thorough and complete, and to fully convey the concept of the present disclosure to those skilled in the art. Features of the various embodiments described may be combined with or substituted for each other, unless expressly excluded or should be excluded based on the context.
[0016] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.
[0017] In the accompanying drawings, the same reference numerals denote the same or similar structural or functional components, and repeated descriptions of them will be omitted in the following description.
[0018] The term "human transport vehicles" in this article encompasses all devices that transport people and / or goods via chain drive, typically such as escalators and moving walkways.
[0019] As mentioned earlier, current lubrication systems for passenger vehicles employ fixed oil supply parameters. For example, a fixed oil supply volume is set based on a range of lifting heights of the passenger vehicle: 600 ml per lubrication interval when the lifting height is less than or equal to 8 m; 1200 ml per lubrication interval when the lifting height is greater than 8 m but less than or equal to 11 m; 1500 ml per lubrication interval when the lifting height is greater than 11 m, and so on. This means that the oil supply may be excessive at shorter lifting heights (e.g., 600 ml at a lifting height of 2 m) and insufficient at longer lifting heights (e.g., 1500 ml at a lifting height of 20 m). Therefore, this disclosure proposes a more flexible method for determining the lubricant supply volume, making the determined supply volume more adaptable and better matched to the specifications of the passenger vehicle, thereby improving the lubrication effect of the passenger vehicle.
[0020] Figure 1 A schematic structure of a manned transportation vehicle is shown.
[0021] refer to Figure 1 The passenger transport vehicle 10 may include components such as a motor 111, a drive wheel 112, a chain 113, steps or pedals 114, handrails 115, and a lubrication system 110. The drive wheel 112 rotates under the action of the motor 111, thereby driving the chain 113. The steps or pedals 114 reciprocate with the movement of the chain 113, thus achieving the transport purpose of the passenger transport vehicle. The chain 113 may include multiple chain segments, and each chain segment may include several chain links 116. The lubrication system 110 may periodically, conditionally, or otherwise supply lubricating oil to the chain 113. Each time lubrication is performed, the lubrication system 110 first determines the amount of lubricating oil required for this lubrication, and then transmits the determined amount of lubricating oil to various brushes located near each chain segment. The brushes are used to evenly apply the lubricating oil to several chain links 116 of the corresponding chain segment. Figure 1 The lubrication system 110 can be implemented as lubrication system 200, lubrication system 300 or lubrication system 400 as described below.
[0022] It should be understood that the structure of the manned transport vehicle 10 disclosed herein is not limited to... Figure 1The structure shown in. The manned transportation vehicle 10 may include a step escalator, a spiral escalator, a ramp escalator, a horizontal moving walkway, or any other device that realizes the transportation of people and / or goods through a chain drive method. For example, when the manned transportation vehicle 10 is a step or spiral escalator, it may include steps 114. When the manned transportation vehicle 10 is a ramp or horizontal moving walkway, it may include treads 114. In addition, Figure 1 The lubrication system 110 is shown as being separated from the main body part of the manned transportation vehicle 10 only for the convenience of illustration, and the lubrication system 110 may be integrated within the main body part of the manned transportation vehicle 10.
[0023] Figure 2 A schematic block diagram showing a lubrication system according to an embodiment of the present disclosure.
[0024] Reference Figure 2 , a lubrication system 200 according to an embodiment of the present disclosure may include an oil storage device 210, a control device 220, an oil distribution device 230, a plurality of brushes 240, etc. The oil storage device 210 is used to store lubricating oil. The control device 220 is used to control the entire lubrication system to perform lubrication operations, including periodically or triggered according to predetermined conditions or otherwise starting lubrication, determining the amount of oil required for this lubrication, controlling the oil pump to pump the determined amount of lubricating oil into the oil distribution device 230, and controlling the brushes to brush the lubricating oil onto the chain links. Among them, when determining the amount of oil required for this lubrication, the control device 220 may determine the amount of oil at least based on the number of steps or treads of the manned transportation vehicle 10 and the size of the chain links 116 in the chain 113. The oil distribution device 230 may distribute the determined amount of lubricating oil pumped from the oil storage device 210 into a plurality of oil paths (for example, P1, P2, P3, P4), and any one of the plurality of oil paths leads to the corresponding chain segment in the chain 113. For example, Figure 1 the chain 113 in may include 4 chain segments SG1, SG2, SG3, and SG4, Figure 1 each chain link 116 in may be numbered from 1 to k in sequence, where the chain links 116 numbered from 1 to m belong to the chain segment SG1, the chain links numbered from m + 1 to i belong to the chain segment SG2, the chain links numbered from i + 1 to j belong to the chain segment SG3, and the chain links numbered from j + 1 to k belong to the chain segment SG4 (m < i - 1, i < j - 1, j < k - 1 and m, i, j, and k are all integers), then the oil paths P1, P2, P3, and P4 may be respectively used to transmit lubricating oil to the chain segments SG1, SG2, SG3, and SG4 in the chain 113. A number of brushes are provided in each chain segment to brush the lubricating oil onto a number of chain links 116 in that chain segment. The number of oil paths shown in the figure as 4 is only for the convenience of illustration, and the number of oil paths is an integer greater than 2.
[0025] The number of steps or pedals is related to the length of chain 113, and the size of chain links 116 is related to the amount of lubricating oil required. Therefore, the amount of lubricating oil determined by considering the number of steps or pedals and the size of chain links 116 in chain 113 is more suitable for the actual needs of passenger transport vehicles, avoiding over- or under-supply of lubricating oil.
[0026] In one example, control device 220 can determine the amount of lubricating oil as proportional to the number of steps or pedals and the surface area of chain link 116. The greater the number of steps or pedals, the more lubricating oil is required. The greater the surface area of chain link 116, the more lubricating oil is required. For example, the amount of lubricating oil can be determined using the following equation 1.
[0027] Z = Q * A * C (Equation 1)
[0028] Where Z is the determined amount of lubricating oil; Q is the number of steps or pedals; A is the surface area of the chain link; and C is a constant. The constant C can be determined based on theoretical calculations, experiments, or experience, and the constant C may differ for passenger transport vehicles that include steps and passenger transport vehicles that include pedals.
[0029] It should be understood that Equation 1 is merely an example used to characterize the relationship between the supply of lubricating oil and the number of steps or pedals and the dimensions of link 116. The control device 220 may also employ other characterization methods, such as determining the supply of lubricating oil as a power function, logarithmic function, exponential function, etc., with respect to the number of steps or pedals and the surface area of link 116.
[0030] Furthermore, in certain special cases, the passenger transport vehicle 10 may include chain links of different sizes. In this case, the control device 220 can first determine the amount of lubricating oil supplied for each size of chain link, and then add the supply amounts for each size of chain link together to obtain the final supply amount.
[0031] In this way, the amount of lubricating oil determined is more accurate and can more precisely meet the lubrication needs of the manned transport vehicle 10.
[0032] Furthermore, the oil quantity determined in the aforementioned manner is the amount of oil pumped from the oil storage device to the oil separator 230 under normal temperature conditions. However, under low temperature conditions, the viscosity of the lubricating oil increases, and the flow resistance increases, so the amount of oil reaching the brush may be much lower than the amount that would reach the brush under normal temperature conditions. To solve this problem, this disclosure proposes the following... Figure 3 The lubrication system of another embodiment shown.
[0033] Figure 3A schematic block diagram of a lubrication system according to another embodiment of the present disclosure is shown.
[0034] See Figure 3 Compared to lubrication system 200, lubrication system 300 according to another embodiment of this disclosure may further include a first temperature sensor 310. The first temperature sensor 310 may be disposed near or inside the oil reservoir 210 to sense the temperature of the lubricating oil at the oil reservoir 210, denoted as a first temperature T1. The first temperature sensor 310 may communicate with the control device 220 via wired or wireless means to transmit the acquired first temperature T1 to the control device 220.
[0035] In this embodiment, once the lubrication operation is initiated, the control device 220 can first determine whether the first temperature T1 is lower than the first temperature threshold th1. If the first temperature T1 is lower than the first temperature threshold th1, the amount of lubricating oil can be determined by considering the first temperature T1 in addition to the number of steps or pedals and the chain link size. For example, the amount of lubricating oil can be determined based on an increasing function of the difference between the first temperature T1 and the first temperature threshold th1. In other words, the amount of lubricating oil is determined based on the difference between the first temperature T1 and the first temperature threshold th1, and the determined amount of oil increases as the difference increases. If the first temperature T1 is not lower than the first temperature threshold th1, the amount of lubricating oil can be determined by considering only the number of steps or pedals and the chain link size. For example, the amount of lubricating oil can be determined using the following Equation 2.
[0036] Z = Q * A * C * F (Equation 2)
[0037] Where Z is the determined amount of lubricating oil; Q, A, and C are the same as those in Equation 1, that is, Q is the number of steps or pedals; A is the surface area of the chain link; and C is a constant. F can increase with the difference between the first temperature T1 and the first temperature threshold th1. In one example, the first temperature threshold th1 is set to 15 degrees; when the first temperature T1 is 14 degrees, F1 is 1.1; when the first temperature T1 is 13 degrees, F1 is 1.2; when the first temperature T1 is 12 degrees, F1 is 1.3, and so on.
[0038] Thus, the amount of lubricating oil pumped from the oil storage device by the lubrication system 300 in a low-temperature environment increases as the temperature decreases, so that the amount of oil that finally reaches the brush is close to the amount of lubricating oil required by the manned transport vehicle 10, thereby improving the lubrication effect at low temperatures.
[0039] Furthermore, when the temperature drops to a certain level, simply increasing the oil supply may still not achieve the desired lubrication effect because the viscosity of the lubricating oil is too high, causing it to accumulate or clog the brushes and making it difficult to evenly cover the chain links. To solve this problem, this disclosure proposes another embodiment of a lubrication system.
[0040] Figure 4 A schematic block diagram of a lubrication system according to yet another embodiment of the present disclosure is shown.
[0041] See Figure 4 Compared to lubrication system 300, lubrication system 400 according to another embodiment of this disclosure may further include a second temperature sensor 410 and a heating device 420. The second temperature sensor 410 may be placed at the oil separator 230 to obtain the temperature of the lubricating oil at the oil separator 230, denoted as the second temperature T2. The heating device 420 may be disposed at the oil separator 230 for heating the lubricating oil at the oil separator 230.
[0042] In one example, the operation of the heating device 420 can be controlled by the control device 220. For example, the control device 220 can generate a first instruction to instruct the heating device to start heating operation when the oil temperature (i.e., the first temperature T1) at the oil reservoir 210 is lower than a first temperature threshold th1, and transmit the first instruction to the heating device 420. In response to receiving the first instruction from the control device 220, the heating device 420 heats the lubricating oil at the oil separator 230. The second temperature sensor 410 can also communicate with the control device 220 via wired or wireless means to transmit the obtained second temperature T2 to the control device 220. The control device 220 can generate a second instruction to instruct the heating device to stop heating operation when the second temperature T2 exceeds the second temperature threshold th2, and transmit the second instruction to the heating device 420. In response to receiving the second instruction from the control device 220, the heating device 420 stops heating the lubricating oil at the oil separator 230. Thus, the lubricating oil at the oil separator 230 is heated to the second temperature threshold th2.
[0043] In another example, the heating operation can also be controlled by the heating device 420 itself. For example, both the first temperature sensor 310 and the second temperature sensor 410 can communicate with the heating device 420 via wired or wireless means to transmit the first temperature T1 and the second temperature T2, respectively, to the heating device 420. The heating device 420 starts heating the lubricating oil at the oil separator 230 in response to the first temperature T1 being lower than a first temperature threshold th1, and stops heating the lubricating oil at the oil separator 230 in response to the second temperature T2 exceeding a second temperature threshold th2.
[0044] In another example, the heating device 420 can be controlled by the control device 220 to start heating, and the heating device 420 itself can control its own shutdown. For example, the control device 220 can generate a first indication to instruct the heating device to start heating when the oil temperature (i.e., the first temperature T1) at the oil reservoir 210 is lower than a first temperature threshold th1, and transmit this first indication to the heating device 420. In response to receiving the first indication from the control device 220, the heating device 420 heats the lubricating oil at the oil separator 230. The second temperature sensor 410 can communicate with the heating device 420 via wired or wireless means to transmit the obtained second temperature T2 to the heating device 420. The heating device 420 can stop heating the lubricating oil at the oil separator 230 in response to the second temperature T2 exceeding the second temperature threshold th2.
[0045] As shown in the figure, the oil separator 230 may include an oil inlet and multiple oil outlets corresponding to multiple oil passages, and internally includes multiple paths from the oil inlet to the multiple oil outlets. In one example, a heating device 420 may be designed as part of the oil separator 230 and may heat the lubricating oil as it flows from the oil inlet to each oil outlet. In this case, the length of the shortest path among the multiple paths satisfies the requirement that the lubricating oil can be heated to a second temperature threshold th2. Furthermore, in this case, a second temperature sensor 410 may be arranged at the oil outlet of the shortest path.
[0046] In this way, the lubrication system 400 can not only increase the supply of lubricating oil in low-temperature environments, but also heat the lubricating oil at the oil separator 230, so that the viscosity of the lubricating oil is reduced and it will not accumulate or clog at the brush, so that it can be evenly brushed onto the chain link surface by the brush and improve the lubrication effect.
[0047] Figure 5 A flowchart illustrating a method performed by a lubrication system according to at least one embodiment of the present disclosure is shown.
[0048] refer to Figure 5 The method 500 performed by a lubrication system according to at least one embodiment of the present disclosure may include steps S510 and S520. In step S510, the amount of lubricating oil required for lubricating the chain of the passenger vehicle is determined based at least on the number of steps or treads of the passenger vehicle and the size of the chain links of the passenger vehicle. In step S520, the determined amount of lubricating oil is distributed into a plurality of oil passages, each of which leads to a chain segment in the chain of the passenger vehicle corresponding to that oil passage. Figure 5 The various steps of method 500 shown can be performed by any one of the aforementioned lubrication systems 200, 300, and 400. Since the preceding steps have already been combined...

[0050] refer to Figure 6 Step S510 may further include sub-steps S511 to S513. In sub-step S511, it can be determined whether the temperature of the lubricating oil at the oil storage device (denoted as the first temperature T1) is lower than the first temperature threshold th1. If the first temperature T1 is lower than the first temperature threshold th1 (i.e., the "Yes" branch in the figure), then proceed to step S512, where the amount of lubricating oil is determined based on the number of steps or pedals of the passenger transport vehicle, the size of the chain links of the passenger transport vehicle, and the first temperature. If the first temperature T1 exceeds the first temperature threshold th1 (i.e., the "No" branch in the figure), then proceed to step S513, where the amount of lubricating oil is determined based on the number of steps or pedals of the passenger transport vehicle and the size of the chain links of the passenger transport vehicle. After step S512 or step S513 is completed, proceed to step S520, where the determined amount of lubricating oil is distributed to multiple oil passages, any one of which leads to the chain segment corresponding to that oil passage in the chain of the passenger transport vehicle. Figure 6 The various steps of method 500 shown can be performed by either the aforementioned lubrication system 300 or 400. Since the preceding steps have already been combined...

[0052] See Figure 7 Method 500 may further include step S530. As shown in the figure, after performing step S512, the process proceeds to step S530, where the determined amount of lubricating oil is distributed to multiple oil passages in multiple chain segments of the chain leading to the manned transport vehicle, and these lubricating oils are heated to a second temperature threshold. As previously described... Figure 4 As described, when the temperature of the lubricating oil at the oil storage device (denoted as the first temperature T1) is lower than the first temperature threshold th1, the heating device 420 heats the lubricating oil at the oil distributor to the second temperature threshold th2. Furthermore, after executing step S513, the process proceeds to step S520, where the determined amount of lubricating oil is distributed to multiple oil passages in multiple chain segments of the chain leading to the manned transport vehicle, without heating these lubricating oils. Figure 7Each step in the method 500 shown can be performed by the lubrication system 400. Since the preceding steps have already been combined...
