[0027] According to a kind of tooling for shift test provided by the utility model, as Figures 1 to 4 shown, this tooling for shift test is used for shift test. This tooling for shift test can cooperate with the shift mechanism to realize simulated shifting, and at the same time, the tester can directly observe the gear position of the shift mechanism at this time through this tooling for shift test. This tooling for shift test includes a tooling body 1 and a test part 2.

[0028] In the following description, reference will be made to Figures 1 to 4 specifically describe the detailed structures of the tooling body 1 and the test part 2 of this tooling for shift test.

[0029] As Figure 3 and Figure 4 shown, in the embodiment, in order to cooperate with this tooling for shift test, the shift mechanism is also correspondingly improved. The shift mechanism includes a shift lever head 3 and a connecting part 4 arranged on the outer peripheral side of the shift lever head 3. The connecting part 4 is connected to the tooling body 1 so that the shift mechanism can be installed on this tooling for shift test, and the shift mechanism can drive the shift lever head 3 to change its position to realize the adjustment of the gear position.

[0030] As Figure 1 and Figure 2 shown, in the embodiment, the tooling body 1 is connected to the connecting part 4 to realize the installation of the shift mechanism. The test part 2 can cooperate with the shift lever head 3 so that the shift lever head 3 can change its position inside the test part 2, thereby simulating the gear position adjustment. For the convenience of installing the shift mechanism, the test part 2 is arranged on the side of the tooling body 1 facing the shift lever head 3, and the shift lever head 3 can be directly arranged inside the test part 2. The test part 2 can include a plurality of shift slots. The shift mechanism drives the shift lever head 3 to move in the shift slots to simulate the shift test. The number of shift slots is multiple. When the shift lever head 3 moves, it can move to the shift slots at different positions respectively. The shift slots at different positions can represent that the shift mechanism is in different gear positions at this time, such as the parking gear, neutral gear, forward gear or reverse gear. The tester can determine the gear position at this time by observing the position of the shift lever head 3 at this time and according to the shift slots, thereby assisting in the shift experiment.

[0031] The overall structure of this tooling for the shift test is simple, lightweight and easy to install. It can conduct tests in limited spaces such as laboratories or offices. The tester can observe the movement of the shift lever 3 and the gear position of the shift mechanism in real time through this tooling for the shift test, saving time and effort, ensuring the orderly progress of the shift test and guaranteeing the test schedule.

[0032] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the test part 2 may include a movable groove body 201 and gear position grooves 202. The movable groove body 201 is arranged in the middle area of the tooling body 1, and the gear position grooves 202 are arranged on both sides of the movable groove body 201. The gear position grooves 202 are connected to the movable groove body 201. Before the shift test, the shift lever 3 is located in the middle of the shift mechanism. When the shift mechanism is connected to the tooling body 1, the shift lever 3 is arranged in the movable groove body 201 located in the middle area of the tooling body 1. During the shift test, according to different shift strategies, the shift lever 3 is driven by the shift mechanism and moves along different directions and grooves to different gear position grooves 202 respectively, that is, in different gear positions. The tester can observe different gear position grooves 202 to observe the movement state of the shift lever 3 in real time and determine the gear position of the shift mechanism.

[0033] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the movable groove body 201 can be formed in an I shape, and the number of gear position grooves 202 is four to correspond to four-speed shifting. The four gear position grooves 202 can be respectively arranged at the four corners of the movable groove body 201. The four gear position grooves 202 can respectively represent the parking gear, neutral gear, forward gear and reverse gear to correspond to a four-speed transmission.

[0034] Preferably, in the embodiment, the movable groove body 201 can also be formed in a king shape, and the number of gear position grooves 202 is six to correspond to six-speed shifting. The six gear position grooves 202 can be respectively arranged at both ends of the three horizontal lines of the king shape. The six gear position grooves 202 can respectively represent the parking gear, neutral gear, forward gear, reverse gear, sport gear and low gear. In this way, this tooling for the shift test can respectively correspond to two types of transmissions to realize different gear tests for different transmissions.

[0035] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, a resistance simulation member 203 is disposed inside the gear position groove 202. When the shift lever 3 is located in the gear position groove 202, the shift lever 3 abuts against the resistance simulation member 203 to simulate the resistance during gear shifting. The resistance simulation member 203 can be disposed at the end of the gear position groove 202 away from the movable groove body 201. When the shift lever 3 moves, it abuts against the resistance simulation member 203, and the resistance simulation member 203 can provide resistance to simulate the resistance during gear shifting.

[0036] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the resistance simulation member 203 is a gas spring. The gas spring has a simple structure and is light in weight, which can make the overall shift test tooling light and convenient for testing, and thus ensure that the test can be carried out in a limited space such as a laboratory or an office.

[0037] Preferably, as Figures 1 to 4 shown, in the embodiment, the tooling body 1 is formed as a rectangular plate member. First connection holes 101 are provided at the four corners of the rectangular plate member, and second connection holes 401 corresponding to the first connection holes 101 are provided at the four corners of the connecting portion 4. The first connection holes 101 and the second connection holes 401 are connected by a connecting member. The first connection holes 101 and the second connection holes 401 can both be formed as bolt holes or pin holes. The connecting member can be, for example, a fastening screw or a pin, and the connection method is a detachable connection. The tester directly docks the four second connection holes 401 of the shift mechanism with the four first connection holes 101 of the tooling body 1 and tightens them with the connecting member. In this way, the shift test tooling is conveniently installed.

[0038] Preferably, as Figures 1 to 4 shown, in the embodiment, the test portion 2 is disposed in the middle area of the tooling body 1, and the test portion 2 is close to the upper side edge of the tooling body 1. The upper side edge here refers to the upper as shown in Figure 1 and Figure 2 shown. The position of the test portion 2 needs to correspond to the shift lever 3. The shift lever 3 is also disposed in the middle area of the shift mechanism and is close to the upper side edge of the shift mechanism.

[0039] Preferably, as Figure 2 shown, in the embodiment, the test portion 2 includes a first axis L1, and the test portion 2 is formed as a symmetric structure with the first axis L1 as the axis of symmetry. The tooling body 1 includes a second axis L2, and the tooling body 1 is formed as a symmetric structure with the second axis L2 as the axis of symmetry. The first axis L1 is perpendicular to the second axis L2.

[0040] Preferably, as Figure 4As shown, in the embodiment, the shift mechanism can further include a shift displacement sensor 5, a gear selection displacement sensor 6, a shift motor 7, and a gear selection motor 8. The shift displacement sensor 5 and the gear selection displacement sensor 6 are arranged on both sides of the shift lever 3, and the shift motor 7 and the gear selection motor 8 are respectively arranged at both ends of the shift mechanism. The shift motor 7 and the gear selection motor 8 can drive the shift lever 3 to move in the X-Y direction through a lead screw inside the shift mechanism. The shift displacement sensor 5 and the gear selection displacement sensor 6 can provide accurate X-Y coordinates, so as to perform precise position control on the shift lever 3.

[0041] The usage process of this shift test tooling is as follows: Connect the shift mechanism to the tooling body 1. When connecting, the first connection hole 101 and the second connection hole 401 can be butted first, and then the shift mechanism and the tooling body 1 are fixed together by four bolts. During the test, the shift motor 7 and the gear selection motor 8 can drive the shift lever 3 to move in the movable groove body 201. The shift lever 3 moves towards the gear position groove 202 in the upper left corner of, for example, Figure 2 simulating the shift process. During the operation of the shift lever 3, it will be subjected to the resistance of the resistance simulation part 203 to simulate the resistance of shifting. Similarly, the process of the shift lever 3 moving towards the other gear position grooves 202 is the same as the above process. According to the movement path of the shift lever 3, a suitable movable groove body 201 can be selected, such as an I-shaped or king-shaped one, to correspond to a four-speed gearbox or a six-speed gearbox respectively.

[0042] This shift test tooling can meet the verification of program functions, and can realize program testing, debugging, and reliability testing of the program and the shift mechanism during the development process of the electronic control program. The overall structure of this shift test tooling is simple and the volume is small, and it can be tested in limited spaces such as laboratories or offices; testers can also observe the movement of the shift lever in real time, solving the problem that it cannot be observed inside the gearbox, saving time and effort, and ensuring the orderly progress of the shift test and the test schedule.

[0043] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto.
