[0031] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to mean “and / or” unless otherwise expressly stated herein.

[0032] In the following description, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0033] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] One embodiment of this utility model relates to a vehicle detachment device. For example... Figure 1 , Figure 2 , Figure 5As shown, XX represents the moving direction of the dynamometer equipment, and YY represents the moving direction of the moving component 4. The vehicle disengagement device includes: a tooling tire assembly 1, a connecting shaft 2, a disengagement motor 3, and a moving component 4. The tooling tire assembly 1 is used to support the vehicle body under test. The two ends of the connecting shaft 2 are connected to the tooling tire assembly 1 and the dynamometer equipment 5, respectively, and the connecting shaft 2 is connected to the tooling tire assembly 1 through a spline structure. The disengagement motor 3 drives the connecting shaft 2 to engage or disengage from the tooling tire assembly 1. The moving component 4 is used to support the tooling tire assembly 1 and the vehicle body under test, and to move the tooling tire assembly 1 and the vehicle body under test away from or into the test position. Specifically, the tooling tire assembly 1 is placed on the moving part 4, and the tooling tire assembly 1 supports the vehicle body under test. The tire drive shaft of the vehicle body under test is connected to the tooling tire assembly 1. The tooling tire assembly 1 is connected to the dynamometer equipment 5 and its torque flange through the connecting shaft 2, so that the required experimental data can be obtained through the dynamometer equipment 5 and its torque flange. At the same time, the connecting shaft 2 is splinedly connected to the tooling tire assembly 1. When it is necessary to separate the tooling tire assembly 1 from the dynamometer equipment 5, the connecting shaft 2 is directly separated from the tooling tire assembly 1 by the disengagement motor 3 and the lead screw cooperating to drive the dynamometer equipment 5. The moving part 4 drives the independent tooling tire assembly 1 and the vehicle body under test to leave the test position.

[0035] As can be seen from the above, since the connecting shaft 2 is connected to the tooling tire assembly 1 through a spline structure, in an emergency, the dynamometer equipment 5 can be quickly removed from the tooling tire assembly 1 by disconnecting the motor 3, so that the tooling tire assembly 1 supports the car under test and is placed on the moving part 4. Directly dragging the moving part 4 can drive the car under test and the tooling tire assembly 1 away from the experimental station, thereby protecting the safety of the laboratory.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 5 As shown, XX represents the moving direction of the dynamometer equipment, and YY represents the moving direction of the moving component 4. The moving component 4 includes: a moving disc that supports the tooling tire assembly 1 and the vehicle body to be tested, and a traction force component connected to the moving disc. This traction force component can be a winch, or a motor and a steel wire traction rope to drive the moving disc. The moving disc can also be a tractor. The moving direction of the moving disc is perpendicular to the detachment direction of the dynamometer equipment 5. The vehicle detachment device also includes: a base 7, on which a track 71 extends toward the axial direction of the tooling tire assembly 1. The dynamometer equipment 5 is mounted on the track 71, and the detachment motor 3 is used to drive the dynamometer equipment 5 to move along the track 71.

[0037] Furthermore, such as Figure 3 , Figure 4As shown, the tooling tire assembly 1 includes: a tooling tire body 11, and an output flange 12 connected to the end face of the tooling tire body 11. The output flange 12 has a spline hole 120, and the connecting shaft 2 is inserted into the spline hole 120. The shaft has an external spline 21.

[0038] Furthermore, such as Figure 3 , Figure 4 As shown, the tooling tire body 11 includes: a hub 111 connected to the tire drive shaft of the vehicle under test, a rim 113 fitted over the hub 111, a tire 114 fitted over the rim 113, and a bearing 112 fitted between the rim 113 and the hub 111. The tire 114, rim 113, bearing 112, hub 111, and output flange 12 are coaxially arranged. The bearing 112 is connected to the rim 113 via a connecting flange 13. The tire 114 is mounted on the moving part 4 and is used to support the vehicle under test. The output flange 12 is fixedly connected to the end face of the hub 111. The tire 114 can be a rubber tire. By adding a bearing 112 between the hub 111 and the tire, the tire does not rotate during testing and only serves to support the test vehicle. The hub 111 rotates normally, outputting the power of the entire vehicle. The hub 111 is connected to the output flange 12, through which power is output.

[0039] In addition, such as Figure 3 , Figure 4 As shown, the hub 111 has a recess 60 on the side facing the dynamometer device 5, and the output flange 12 has a protrusion 121 that is embedded in the recess 60. The spline hole 120 is opened on the protrusion 121 and extends through the output flange 12 along the axial direction of the hub 111.

[0040] Furthermore, such as Figure 3 , Figure 4 As shown, the hub 111 has a peripheral body 61 on the side facing the dynamometer device 5, and the peripheral body 61 forms a recess 60 around the axis of the hub 111. The output flange 12 also has a flange body 122 connected to the protrusion 121. The flange body 122 covers the side of the peripheral body 61 facing the dynamometer device 5 and is fixedly connected to the peripheral body 61. The flange body 122 and the peripheral body 61 can be fixedly connected by bolts.

[0041] Furthermore, such as Figure 3 , Figure 4 As shown, the output flange 12 is embedded into the side of the tooling tire body 11 facing the dynamometer device 5, and the side of the output flange 12 facing the dynamometer device 5 does not protrude from the tire, thus the outer surface of the tooling tire has a higher flatness.

[0042] In addition, such as Figure 1 , Figure 2 , Figure 5As shown, there are multiple tooling tire assemblies 1, which are respectively installed on both sides of the vehicle body under test, and each tooling tire assembly 1 is connected to a connecting shaft 2 and a dynamometer device 5. Understandably, there can be four tooling tire assemblies 1, which are respectively installed at the wheel positions of the vehicle body under test.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 5 As shown, the connecting shaft 2 is fixedly connected to the dynamometer device 5 and its torque flange by screws 8.

[0044] Another embodiment of this utility model relates to an automotive powertrain testing system. The automotive powertrain testing system includes: a vehicle disengagement device as described in the above embodiment, and a dynamometer device 5. The dynamometer device 5 is splinedly connected to the tooling tire assembly 1 via a connecting shaft 2 for easy disassembly.

[0045] It is not difficult to see that this embodiment is a system implementation corresponding to the first embodiment, and this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.
