Description

Technical Field

[0001] This invention relates to the field of automotive hybrid powertrain technology, and in particular to a connecting bracket assembly for improving hybrid powertrain modes. Background Technology

[0002] Existing hybrid powertrains separate the P1 generator and P3 drive motor and mount them on the gearbox assembly. This results in a reduction in hybrid powertrain modes. Combined with the vibrations of various powertrain components, the hybrid powertrain is prone to periodic fluctuations in vibration amplitude, which can generate noise and affect vehicle comfort.

[0003] Different vehicle models are often equipped with P1 generators and P3 drive motors with different power and torque. Because of the difference in power and torque, these motors usually have different maximum outer diameter and axial dimensions. This results in a large variety and number of connecting brackets for the hybrid powertrain, making it difficult to prevent errors during factory assembly. Dimensions, tolerances and assembly surface precision lead to unstable assembly quality, which in turn causes manufacturing quality problems, significantly increases development and production costs, and easily leads to rework and customer complaints.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a connecting bracket assembly for improving the hybrid powertrain mode, including an axial connecting unit 100 and a longitudinal connecting unit 200. The axial connecting unit 100 includes a first connecting bracket 101 and a second connecting bracket 102. The first connecting bracket 101 is connected to the P1 generator P1 by a first bolt 101a, and the second connecting bracket 102 is connected to the P3 drive motor P3 by a second bolt 102a. The longitudinal connecting unit 200 includes a longitudinal connecting plate 201. The longitudinal connecting plate 201 has a U-shaped elongated hole 201a. The longitudinal connecting plate 201 and the first connecting bracket 101 are perpendicular to each other and fixedly connected.

[0034] The first connecting bracket 101 is matched with the surface of the P1 generator P1 on one side, and a number of mounting holes 101b are opened at one end of it. The arrangement direction of the mounting holes 101b is consistent with the arrangement direction of the bolts on the P1 generator P1.

[0035] The second connecting bracket 102 is matched with the surface of the P3 drive motor P3 on one side, and a number of mounting holes 102b are opened at one end of it. The arrangement direction of the mounting holes 102b is consistent with the arrangement direction of the bolts on the P3 drive motor P3.

[0036] The second connecting bracket 102 is located between the first connecting bracket 101 and the P3 drive motor.

[0037] The second connecting bracket 102 has a longitudinal bolt hole 102c at one end, which corresponds to the U-shaped elongated hole 201a.

[0038] The first bolt 101a is installed in the same direction as the bolts that come with the P1 generator, and the second bolt 102a is installed in the same direction as the bolts that come with the P3 drive motor.

[0039] The end faces of the mounting bolts for generator P1 and drive motor P3 are parallel to each other.

[0040] Two U-shaped elongated holes 201a are provided, and their length sides are consistent with the bolt installation direction of P1 generator P1 and P3 drive motor P3.

[0041] The longitudinal connecting plate 201 is connected to the second connecting bracket 102 by a third bolt 201b, which can be installed at different positions along the length of the U-shaped elongated hole 201a.

[0042] The first bolt 101a, the second bolt 102a, and the third bolt 201b are all M8×1.25 bolts.

[0043] The end faces of the first connecting bracket 101 and the second connecting bracket 102 are parallel to each other, but are offset at a certain angle, so that there is enough operating space for installing and removing the first bolt 101a and the second bolt 102a.

[0044] One side of the first connecting bracket 101 matches the surface of the P1 generator P1, and one side of the second connecting bracket 102 matches the surface of the P3 drive motor P3.

[0045] This invention adopts a split dual-motor bracket for the connecting bracket assembly, which connects the P1 generator and the P3 drive motor respectively, solving the problem of excessive cumulative tolerance of the two motor design dimensions affecting the fit of the bracket mounting surface, resulting in a compact structure.

[0046] The first connecting bracket 101 and the second connecting bracket 102 of the connecting bracket assembly of the present invention adopt one-sided two-pin positioning. The diameter of the bolt hole of the connecting bracket is 2.5mm larger than the bolt diameter, which can eliminate the influence of the design or manufacturing position of the bolt hole on the motor bracket on the assembly of the connecting bracket and improve the assembly accuracy between parts.

[0047] In this case, the two motor brackets of the connecting bracket assembly are installed laterally using two bolts, which eliminates the impact of poor fit caused by the positional tolerance of the motor bolt holes and the positional tolerance of the bracket mounting holes on the assembly.

[0048] Example 2

[0049] Reference Figures 4-9This is the second embodiment of the present invention, which differs from the previous embodiment in that: the longitudinal connecting unit 200 includes a longitudinal connecting plate 201, the longitudinal connecting plate 201 has a U-shaped elongated hole 201a, and the longitudinal connecting plate 201 and the first connecting bracket 101 are perpendicular to each other and fixedly connected.

[0050] The second connecting bracket 102 has a longitudinal bolt hole 102c at one end, which corresponds to the U-shaped elongated hole 201a.

[0051] Two U-shaped elongated holes 201a are provided, and their length sides are consistent with the bolt installation direction of P1 generator P1 and P3 drive motor P3.

[0052] The longitudinal connecting plate 201 is connected to the second connecting bracket 102 by a third bolt 201b, which can be installed at different positions along the length of the U-shaped elongated hole 201a.

[0053] The bolt installation direction of the connecting bracket assembly of the present invention is consistent with the bolt installation direction of the motor. The U-shaped elongated hole 201a is provided on the longitudinal connecting plate 201, which can match and install motors with different power and different axial dimensions. It can also eliminate the influence of the fit between the mounting surfaces of the connecting bracket caused by the axial design or assembly error of the two motors.

[0054] When the third bolt 201b connects the longitudinal connecting plate 201 and the second connecting bracket 102, although it remains constant relative to the second connecting bracket 102, the length of the second connecting bracket 102 relative to the U-shaped elongated hole 201a can change. That is, the position of the second connecting bracket 102 relative to the longitudinal connecting plate 201 can move up and down. When the axial dimensions of the P1 generator and the P3 drive motor are significantly different, the distance between the second connecting bracket 102 and the longitudinal connecting plate 201 can be appropriately increased, and vice versa.

[0055] Similarly, when the P1 generator / P3 drive motor is working, the vibration it generates can be partially buffered by the design of the U-shaped elongated hole 201a, because the third bolt 201b can move relative to the U-shaped elongated hole 201a along with the vibration.

[0056] Example 3

[0057] Reference Figures 1-9 This is the third embodiment of the present invention, which differs from the previous two embodiments in that: the installation direction of the first bolt 101a is consistent with the installation direction of the bolts on the P1 generator P1, and the installation direction of the second bolt 102a is consistent with the installation direction of the bolts on the P3 drive motor P3.

[0058] The first bolt 101a, the second bolt 102a, and the third bolt 201b are all M8×1.25 bolts.

[0059] The bolts connecting the bracket assembly of the present invention, namely the first bolt 101a and the second bolt 102a, are installed in the same direction as the bolts of the P1 generator / P3 drive motor, and are also arranged in the same way. The P1 generator / P3 drive motor is arranged according to a certain radius of curvature, and the corresponding first bolt 101a and second bolt 102a are also arranged according to the same radius of curvature.

[0060] The bolts used for connecting brackets are all of the same specification, using M8×1.25 bolts, which reduces the types of bolts used, makes them standardized and replaceable, and facilitates worker operation.

[0061] The bolts used in this case to connect the bracket assembly are all external hexagonal flange bolts. The assembly process involves pre-tightening and then applying torque, which improves the fit between the mounting surfaces and makes the assembly simple and reliable.
