Description

Technical Field

[0001] This utility model relates to range-extended drive axle testing, and in particular to an adapter plate for a range-extended drive axle test bench. Background Technology

[0002] Currently used drive axle wheel-side torque dynamometers employ a disc connection method. However, the actual market demands testing various axle types, including those with and without hubs. Hub-type axles typically have wheel mounting surfaces, allowing for direct disc connection to the dynamometer. Hubless axles require custom-designed adapters for connection, often employing a disc-welded structure that mates with the axle housing. These adapters are designed to accommodate different wheel mounting requirements, resulting in poor versatility and unsuitability for testing diverse drive axles. Therefore, addressing the limited output shaft diameter options, this paper proposes an assembled adapter that converts the radial connection of the drive axle output shaft to an end-face disc connection.

[0025] like Figures 1-5As shown, an adapter plate for a range-extended drive axle test bench includes an upper pressure plate 3, a lower pressure plate 5, and a dynamometer connecting plate 1. The dynamometer connecting plate 1 has several mounting holes. The upper pressure plate 3 and the lower pressure plate 5 are detachably connected, and a mounting cavity is formed between them. An axially extending keyway is provided on the upper pressure plate 3 and / or the lower pressure plate 5. The mounting surfaces of the upper pressure plate 3 and the lower pressure plate 5 are aligned. The dynamometer connecting plate 1 is detachably mounted on the mounting surfaces of the upper pressure plate 3 and the lower pressure plate 5. On the surface, during use, after pressing the flat key Z2 onto the drive axle output shaft Z1, align the keyway position of the upper pressure plate 3 with the flat key Z2 on the drive axle output shaft Z1, then press the upper pressure plate 3 and the lower pressure plate 5 together, and install the dynamometer connecting plate 1 on the end faces of the upper pressure plate 3 and the lower pressure plate 5, thereby realizing the transformation of the radial connection of the drive axle output shaft Z1 into an end face plate connection structure. Finally, the connection requirements of the drive axle wheel-side torque dynamometer can be realized through the mounting holes on the dynamometer connecting plate 1.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the upper pressure plate 3 and the lower pressure plate 5 are locked together by locking screws 4. Furthermore, the upper pressure plate 3 has a countersunk screw hole that extends toward the lower pressure plate 5. The lower pressure plate 5 has a locking screw 4 through hole corresponding to the countersunk screw hole. The upper pressure plate 3 and the lower pressure plate 5 are locked together by locking screws 4 installed in the corresponding countersunk screw hole and threaded through hole, and the head of the locking screw 4 is located in the countersunk screw hole. When the upper pressure plate 3 and the lower pressure plate 5 are joined together, the corresponding countersunk screw hole and threaded through hole are aligned, and then locked together by locking screws 4.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the front ends of the upper pressure plate 3 and the lower pressure plate 5 are both provided with semi-circular connecting plates. The two semi-circular connecting plates form a flange. The connecting plates are provided with through holes. The dynamometer connecting plate 1 is locked to the flange by locking bolts 2. After the upper pressure plate 3 and the lower pressure plate 5 are locked by locking screws 4, the dynamometer connecting plate 1 is then locked to the flange by locking bolts 2. Furthermore, both the upper pressure plate 3 and the lower pressure plate 5 are semi-circular arc structures, and after the upper pressure plate 3 and the lower pressure plate 5 are spliced, there is a gap between their splicing surfaces. Preferably, the gap between the splicing surfaces of the upper pressure plate 3 and the lower pressure plate 5 is 0.5~2mm. Therefore, the upper pressure plate 3 and the lower pressure plate 5 have a movable gap during the merging process, which can better clamp the drive axle output shaft Z1.

[0028] In this embodiment, as Figure 1 As shown, the mounting holes 11 are evenly distributed on the same circumference. The dynamometer connecting plate 1 is also symmetrically provided with two positioning holes. Positioning can be achieved through the positioning holes, which are used to position the torque dynamometer. The mounting holes are used for installation with the torque dynamometer.

[0029] The working process of this utility model is as follows: When in use, after pressing the flat key Z2 onto the output shaft Z1 of the drive axle, align the keyway position of the upper pressure plate 3 with the flat key Z2 on the output shaft Z1 of the drive axle, and then press the upper pressure plate 3 and the lower pressure plate 5 together with the locking screw 4. After tightening the locking screw 4, use the locking bolt 2 to install the dynamometer connecting plate 1 on the end face of the upper pressure plate 3 and the lower pressure plate 5, thereby realizing the transformation of the radial connection of the output shaft Z1 of the drive axle to the end face plate connection structure. Finally, the connection requirements of the drive axle wheel-side torque dynamometer can be realized through the mounting hole on the dynamometer connecting plate 1.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
