Description

Technical Field

[0001] The utility model belongs to the technical field of transmission test, and in particular relates to a mounting assembly for adapting a test bench to a transmission. Background Art

[0002] With the rapid development of the automobile industry, the use of automatic transmissions in automobiles is a development trend, and the proportion of cars equipped with automatic transmissions has increased rapidly in recent years. Automatic transmissions are favored by the market for their advantages such as simple operation, seamless shifting, extended life of engines and transmission components, and improved and enhanced vehicle power. Therefore, test benches for automatic transmissions have also received much attention.

[0003] However, the installation components of the existing MT test bench do not meet the test requirements of the AT transmission. The AT transmission test requires the installation of a brake plate to match the torque converter of the AT transmission. The brake plate needs to be installed on the simulated crankshaft for connection and matching. The existing test bench simulated crankshaft adapter flange has 6 holes, and the AT brake plate has 8 holes. The installation of the AT brake plate requires bolts to be tightened from the inside of the front casing, that is, the rear side of the transmission support. The existing simulated crankshaft adapter flange and MT bench support cannot meet the AT transmission test; secondly, the structure and size of the AT transmission front casing are different from those of the MT. There is no mounting plate that fits the front holes of the front casing, and it cannot meet the AT test. Therefore, in order to meet the AT transmission bench test, a set of tooling that can adapt to the AT transmission test is needed to modify the test bench so that the bench can meet both the MT transmission test requirements and the AT transmission test requirements. Utility Model Content

[0004] The utility model aims to provide a mounting assembly for adapting a test bench to a transmission, which can take into account both the bench test installation of an MT transmission and the bench test installation of an AT transmission.

[0005] The technical solution adopted by the utility model is:

[0006] A mounting assembly for adapting a test bench to a transmission comprises an AT transmission mounting plate, an adapter flange 1 and an adapter flange 2; the AT transmission mounting plate is mounted on the front side of a transmission support of an MT test bench, and mounting holes are arranged on the AT transmission mounting plate according to the size and position of the aperture of a front housing of the AT transmission to be tested; the adapter flange 1 is connected to a simulated crankshaft of the MT test bench through 6 bolts 1, the adapter flange 2 is connected to the adapter flange 1 through 8 bolts 2, and the adapter flange 2 is connected to the AT transmission.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The utility model has a simple and reasonable structure, and cleverly simulates the design of the crankshaft adapter flange to solve the installation problem of 8 holes on the AT brake plate by using two matching adapter flanges of "6 holes to 8 holes" and "8 holes to 8 holes". The existing MT stand support is cut with holes to meet the needs of installing the AT brake plate; and a mounting plate is designed to meet the hole requirements of the front casing of the AT transmission.

[0009] The utility model can take into account both the bench test installation of the MT transmission and the bench test installation of the AT transmission. Due to the improvement of the structure of the gearbox support, the adapter flange, the simulated crankshaft assembly and the mounting plate, the problem of the simulated crankshaft not matching the AT transmission brake plate and the mounting plate not matching is avoided, and the coaxiality of the brake plate, the torque converter and the test bench drive motor during the AT transmission test is maintained, so that the test bench meets the AT transmission test requirements.

[0019] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 8 As shown, the utility model is to connect the MT test bench with the tested AT transmission through the installation assembly, so that the purpose of subsequent testing can be carried out. Therefore, the simulated crankshaft adapter flange and AT transmission mounting plate are designed according to the actual size of the AT transmission to ensure the successful installation of the AT transmission. First refer to Figure 1 to Figure 4 As shown, it includes an AT transmission mounting plate 2, an adapter flange 1 4 and an adapter flange 2 5; the AT transmission mounting plate 2 is installed on the front of the gearbox support 1 of the MT test bench, and the AT transmission mounting plate 2 sets the mounting holes according to the size and position of the aperture of the front housing of the AT transmission to be tested; there is a simulated crankshaft 3 inside the MT test bench, and the front hole position of the simulated crankshaft 3 is evenly divided into 6 holes, while the hole position on the AT transmission brake plate is evenly divided into 8 holes, so it is necessary to cooperate with the adapter flange 1 and the adapter flange 2 to realize the tooling conversion of "6 holes to 8 holes". The adapter flange 1 4 is connected to the simulated crankshaft 3 of the MT test bench through 6 8.8-grade M10 bolts 1 6 with a length of 20mm, the adapter flange 2 5 is connected to the adapter flange 1 4 through 8 bolts 2 8, and the adapter flange 2 5 is connected to the AT transmission.

[0021] like Figure 7 , Figure 8 As shown, the outermost side of the AT transmission mounting plate 2 is penetrated by 6 holes evenly distributed in a counterclockwise rotation of 8°, and three M16 bolts with a hardness of 8.8 and a length of 50mm are used to fix the transmission support 1 and the AT transmission mounting plate 2. A steel gasket is placed between the transmission support 1 and the AT transmission mounting plate 2 to increase the contact surface, reduce friction and prevent loosening. The transmission support 1 and the AT transmission mounting plate 2 are positioned by a stopper.

[0022] like Figure 7 , Figure 8 As shown, a threaded hole is drilled just above the AT transmission mounting plate 2 for inserting a lifting ear to facilitate installation and disassembly.

[0023] like Figure 3 As shown, the adapter flange 14 has 6 countersunk through holes evenly distributed on the inner side and is provided with a concave stopper for fixing with the convex stopper of the simulated crankshaft 3. The 6 countersunk through holes are used to install bolts 6. The adapter flange 14 is fixed to the simulated crankshaft 3 by 6 8.8-grade M10 bolts 6 with a length of 20 mm on the inner side. The adapter flange 14 has 6 through threaded holes evenly distributed on the outer side for fixing the adapter flange 2 5. A convex stopper and a locating pin 7 are provided on the front side of the adapter flange 4 for positioning the adapter flange 2 5, thereby ensuring coaxiality.

[0024] like Figure 4As shown, the adapter flange 25 is fixed by the stopper on the adapter flange 14, and the adapter flange 25 and the adapter flange 14 are positioned by two locating pins 7 to improve the assembly accuracy, enhance its stability, and ensure its coaxiality. Corresponding to the 6 threaded holes arranged on the outside of the adapter flange 4, 6 countersunk holes are arranged on the outer ring of the adapter flange 25, and highland barley paper gaskets 9 are placed. The 6 countersunk holes are used to install bolts 28, which are installed and fixed to the adapter flange 4 by bolts 28 of 12.9 grade M10 and 30 mm in length. 8 threaded through holes 10 are evenly distributed on the inner ring of the adapter flange 25 and a convex stopper is provided to cooperate with the AT transmission brake plate.

[0025] If there are other test requirements, such as temporarily testing an MT transmission for endurance testing, the adapter flange 1 4 and the adapter flange 2 5 can be removed and replaced with the corresponding model of the simulated crankshaft 3 adapter flange and the mounting plate, so that the MT test bench can be adapted to the AT transmission.

[0026] like Figures 5 to 8 As shown, the AT transmission mounting plate 2 is provided with an AT transmission brake plate mounting hole 12 ; the transmission support 1 is provided with a corresponding cutting hole 11 .
