Generally speaking, a dog clutch comprises a pair of claw plates and a sleeve capable of relative movement between the two claw plates, wherein the two claw plates are respectively provided with claw teeth, and the sleeve is provided with sleeve teeth capable of respectively cooperating with the claw plate teeth of the two claw plates.

[0003] In order to enable the sleeve to move so that the sleeve teeth can engage with the corresponding claw plate teeth to transmit torque, an actuator (DCA) for a dog clutch is generally required to complete the above displacement of the sleeve.

[0004] Such an actuator generally includes a power source such as a motor and an actuating member such as a shift fork for engaging with the sleeve to drive the sleeve to move.

[0005] In the prior art, in order to conduct type tests or verification tests on various actuators designed and produced for claw clutches, it is often necessary to install the obtained actuators on real claw clutches for testing.

[0006] In this case, on the one hand, the actuator to be tested needs to be installed in combination with the claw clutch sleeve that it can cooperate with, which places too high a requirement on the test clutch, and the test tooling is often not universal and needs special design; on the other hand, the actual claw clutch device often does not have the conditions for installing various sensors to better monitor the progress of the test.

[0054] Reference will now be made in detail to embodiments of the present invention, examples of which are shown in the accompanying drawings and described below.

[0055] Although the utility model will be described in conjunction with exemplary embodiments, it should be appreciated that this specification is not intended to limit the utility model to those exemplified embodiments. On the contrary, the utility model is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms and other embodiments that can be included in the spirit and scope of the utility model.

[0056] In order to facilitate explanation and accurately define the technical solutions of the present invention, the terms “upper”, “lower”, “inner” and “outer” are used to describe features of the exemplary embodiments shown in the drawings with reference to their positions.

[0057] Now first refer to Figure 1 , which shows a preferred embodiment of a test device for performing a simulated load test on an actuator for a claw clutch according to the utility model.

[0058] like Figure 1 As shown in FIG. , the test equipment includes an actuator mounting frame 100, a clutch claw plate simulation member 200, a clutch sleeve simulation member 300, a drive mechanism 400,

[0059] The following references Figures 1 to 3 The preferred embodiments of the various parts of the above-mentioned testing equipment are described in detail.

[0060] The actuator mounting frame 100 is used to receive and fix the actuator 1000 to be tested. In a preferred embodiment, for example, see Figure 3 The actuator mounting frame 100 may include a fixed support portion 110 and a support portion 110 that can rotate orthogonal to the tooth engagement direction X (as described below, see Figure 2 The swing pivot axis (in the vertical direction) Figure 2 The swing mounting portion 120 is pivotally mounted on the fixed support portion 110 (approximately along the horizontal direction), and the actuator 1000 to be tested can be mounted on the swing mounting portion 120.

[0061] It should be noted here that the above description of the specific structure of the actuator mounting frame 100 is only for illustration. For example, although the swing mounting portion 120 shown in the figure is mounted on the fixed support portion 110 at a substantially top position of the fixed support portion 110, those skilled in the art can also set the swing mounting portion 120 in the middle or near the bottom in the vertical direction of the fixed support portion 110 according to actual needs, as long as at least the relative movement of the two components can be achieved. In addition, the actuator mounting frame 100 can also be integrally formed as a single immovable component, as long as it can be installed for the actuator 1000 to be tested.

[0062] See also Figure 2 , the clutch claw plate simulation member 200 includes claw plate teeth 210. More specifically, in Figure 2 In the preferred embodiment shown in FIG. 1 , the clutch claw plate simulation member 200 may include two rows of claw plate teeth 210 arranged in parallel and opposite to each other, namely, one row located at Figure 2 In the middle, the other row is located at the top Figure 2 In a lower position relative to the aforementioned row.

[0063] Continue to see Figure 2 The clutch claw plate simulation member 200 may include a clutch claw plate simulation plate 220, and a receiving opening 221 is provided in the clutch claw plate simulation plate 220. For example, the claw plate teeth 210 may be arranged at the edge of the receiving opening 221 of the clutch claw plate simulation plate 220.

[0064] Similar to the clutch claw plate simulation member 200, and as Figure 2 As shown in FIG. 1 , the clutch sleeve simulation 300 includes sleeve teeth 310 that can cooperate with the claw plate teeth 210. Preferably, the clutch sleeve simulation 300 may include two rows of sleeve teeth 310 that cooperate with the two rows of claw plate teeth 210, that is, one row located at Figure 2 The middle row is close to the upper side and matches with the claw plate teeth 210 above it, and the other row is located at Figure 2 The middle is located at a lower position relative to the aforementioned row and cooperates with the claw plate teeth 210 below it.

[0065] See also Figure 3 According to a preferred embodiment, the clutch sleeve simulation part 300 can be designed to be engaged with the fork 1100 of the actuator 1000 to be tested and driven by the fork 1100 to move in the tooth engagement direction X. For example, by way of example but not limitation, the clutch sleeve simulation part 300 is provided with grooves on both sides along the rotation simulation direction Y for the fork head of the fork 1100 of the actuator 1000 to be tested to achieve engagement with the fork 1100.

[0066] Continue to see Figure 2 The clutch sleeve simulation member 300 may include a clutch sleeve simulation plate 320, which is coplanarly arranged with the clutch claw plate simulation plate 220 and accommodated in the receiving opening 221. Those skilled in the art can further specifically coordinate and design the desired dimensions of the clutch claw plate simulation plate 220 and the clutch sleeve simulation plate 320 according to actual needs, especially the relative movement requirements of the clutch sleeve simulation plate 320 relative to the clutch claw plate simulation plate 220, which will not be described in detail here, and it should be emphasized that the shapes and dimensions of the two shown in the figure are only for illustration, and are not intended to be within the scope of the present utility model.

[0067] In order to meet more diverse testing requirements, a preferred embodiment of the testing equipment according to the present invention may include more than one clutch claw plate simulation 200 and more than one clutch sleeve simulation 300 respectively matched with the clutch claw plate simulation 200 as shown in the figures, for example, including two clutch claw plate simulations 200 and corresponding two clutch sleeve simulations 300.

[0068] It can be understood that the shapes of the above-mentioned claw plate teeth 210 and sleeve teeth 310 can be set in the form of rectangular teeth, for example, with reference to a real clutch, except that the rectangular teeth of a real clutch are arranged on the circumference, so that they are rectangular when unfolded in the circumferential direction, but the above-mentioned claw plate teeth 210 and sleeve teeth 310 can be arranged on the clutch claw plate simulation plate 220 and the clutch sleeve simulation plate 320 in a substantially flat state and are rectangular teeth distributed in a plane. It should also be pointed out that the above-mentioned description of the shapes of the claw plate teeth 210 and the sleeve teeth 310 is only for illustration, and those skilled in the art can also select the shapes of the clutch claws of various other shapes according to actual needs, as long as the claw plate teeth 210 and the sleeve teeth 310 can cooperate with each other.

[0069] The driving mechanism 400 is configured to allow relative movement of the clutch claw plate simulation member 200 and the clutch sleeve simulation member 300 in a rotation simulation direction Y orthogonal to the gear engagement direction X.

[0070] More preferably, and as the preferred embodiment shown in the figure, the drive mechanism 400 only drives the movement of the clutch claw plate simulation member 200. In this case, the clutch sleeve simulation member 300 remains relatively fixed in the rotation simulation direction Y.

[0071] The driving mechanism 400 may adopt various common power sources and transmission mechanisms, including but not limited to the combination of an electric motor and a reduction gear, which will not be elaborated here. Those skilled in the art can select various common technologies to implement it according to actual needs.

[0072] In addition, the installation position of the drive mechanism 400 and its corresponding matching relationship with the clutch sleeve simulation member 300 are also only for illustration. Those skilled in the art can arrange the drive mechanism 400 on one or both sides of the left and right sides of the clutch sleeve simulation member 300 according to actual needs. Moreover, a single drive mechanism 400 can be used as a drive member of one or more clutch sleeve simulation members 300.

[0073] Continue to refer Figure 2 The test equipment further includes a claw plate guide rail 230 and a sleeve guide rail 330. The claw plate guide rail 230 is used for the clutch claw plate simulation plate 220 to be guided to move along it, and the sleeve guide rail 330 is used for the clutch sleeve simulation member 300 to be guided to move along it. In the preferred embodiment described above, the claw plate guide rail 230 can be substantially along the rotation simulation direction Y, i.e. Figure 2 The sleeve guide rail 330 can be arranged in the horizontal direction of the tooth engagement direction X, that is, Figure 2 The vertical arrangement in the experiment can meet the movement requirements of the corresponding simulation board in the experimental test.

[0074] It should be pointed out that the above-mentioned claw plate guide rail 230 and sleeve guide rail 330 can be integrally or detachably fixed with the fixed support portion 110 of the actuator mounting frame 100. In addition, although the claw plate guide rail 230 and sleeve guide rail 330 shown in the figure are respectively located below the corresponding clutch claw plate simulation member 200 and clutch sleeve simulation member 300 and are in the form of groove rails, the specific arrangement of the claw plate guide rail 230 and sleeve guide rail 330 is not limited thereto, but can also be arranged above or in the same horizontal plane relative to the clutch claw plate simulation member 200 and the clutch sleeve simulation member 300, and the specific shape of the claw plate guide rail 230 and sleeve guide rail 330 is not limited to the groove rail, but can also adopt various other solid or non-solid guide rail forms, such as electromagnetic guidance or image recognition guidance, etc., which will not be repeated here to save space.

[0075] Return to reference Figure 1 The test device may also preferably include a sleeve displacement sensing device 500. Figure 1 and Figure 2 In the preferred embodiment shown in the figure, the sleeve displacement sensing device 500 is connected to the clutch sleeve simulation member 300, for example, by engaging with the clutch sleeve simulation plate 320, to indicate the movement stroke of the fork 1100 of the actuator 1000 to be tested.

[0076] However, it can be understood by those skilled in the art that the sleeve displacement sensing device 500 itself is optional, and the installation position and method of the sleeve displacement sensing device 500 are not limited thereto, as long as it can reflect the movement stroke of the shift fork of the actuator to be tested by sensing the displacement of the sleeve displacement sensing device 500. For example, the sleeve displacement sensing device 500 may include a sensing device that senses the displacement and displacement amount of the clutch sleeve simulation 300 by non-contact means such as image recognition, and in this case, optionally, a sensing tag may be set on the sensing clutch sleeve simulation 300 according to requirements.

[0077] In addition, similar to the above-mentioned driving mechanism 400 , in the case of having a plurality of clutch sleeve simulations 300 , a single sleeve displacement sensing device 500 may be used to sense the displacement of one or more clutch sleeve simulations 300 .

[0078] The test apparatus further comprises a load sensing element 600 fixed relative to the fixed support 110 , the load sensing element 600 being engaged with the swing mount 120 so as to sense an external moment about the swing pivot axis to which the swing mount 120 is subjected. Figure 1 The specific implementation of a load sensing element 600 in the form of a load element is shown as an example, which senses the torque by converting the torque received by the swing mounting portion 120 into a force substantially along the tooth engagement direction X through a swing arm fixedly connected to the swing mounting portion 120 and a corresponding connecting rod transmission mechanism. However, those skilled in the art can imagine that other various types of load sensing elements 600 not shown can also be applied to the basic structure of the test device of the present invention to sense the external torque received by the swing mounting portion 120, which will not be described in detail here.

[0079] A test method for performing a simulated load test on an actuator for a claw clutch using a test device according to the above disclosure will be briefly described below in conjunction with the accompanying drawings.

[0080] The test method includes the following steps in sequence:

[0081] Teeth engagement step: engaging at least a portion of the claw plate teeth 210 of the clutch claw plate simulation 200 with corresponding sleeve teeth 310 of the clutch sleeve simulation 300;

[0082] Preloading step: generating a positive pressure along the rotational simulation direction Y on the engagement surface between the corresponding claw plate teeth 210 and the sleeve teeth 310 by means of the push-pull action of the driving mechanism 400 in the rotational simulation direction Y; and

[0083] The step of actuating the gear shifting is as follows: the actuator 1000 to be tested is started, so that the shift fork 1100 applies a gear shifting force in the gear shifting direction X to the clutch sleeve simulation part 300 .

[0084] Those skilled in the art will appreciate that the above-mentioned out-of-gear force can be regarded as a kind of friction force, and its magnitude may at least be related to the above-mentioned positive pressure along the rotation simulation direction Y. However, the influencing factors of the above-mentioned out-of-gear force may not be limited thereto, and may also involve, for example, the specific shapes of the claw plate teeth 210 and the sleeve teeth 310, the number of teeth matched, the specific materials of the tooth surface, etc.

[0085] In addition, preferably, the testing method may also include a gear-out force adjustment step after the gear-out actuation step: the size of the gear-out force is obtained by converting the external torque sensed by the load sensing element 600, and the clutch claw plate simulation 200 and the clutch sleeve simulation 300 are further driven by the driving mechanism 400 to move relative to each other in the rotation simulation direction Y to change the gear-out force until the gear-out force reaches the expected value.

[0086] Preferred embodiments of the present invention have been described in detail above, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0087] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
