Description

Technical Field

[0001] This invention belongs to the field of vehicle engineering technology, and specifically relates to a wide-range adjustable powertrain assembly bracket. Background Technology

[0002] Many armored vehicles now use integrated powertrains, which combine the engine, transmission, and auxiliary systems into a single unit. This unit is assembled externally and then hoisted into the vehicle body. Before the integrated powertrain is installed into the vehicle body, it requires assembly, dimensional inspection, and on-site functional testing.

[0003] Powertrain assembly brackets not only enable rapid powertrain assembly and dimensional inspection, but also provide a support platform for powertrain functional debugging, playing a crucial role in the entire process of powertrain installation, dimensional inspection, functional debugging, and maintenance. Currently, a unique powertrain assembly bracket is designed and manufactured for each vehicle model. A typical powertrain assembly bracket consists of three parts: a base, an engine mounting bracket, and a transmission mounting bracket. The base is welded from channel steel, the engine mounting bracket is welded to the base according to the vehicle's dimensions, and the transmission mounting bracket is bolted to the base. Existing powertrain assembly brackets have the following problems:

[0004] 1. Because the typical power unit mounting bracket adopts the method of welding the base to the engine mounting bracket, the powertrain mounting bracket is only suitable for powertrain assembly of one type of vehicle. It is basically unsuitable for other types of vehicles. Each type of vehicle requires re-processing of the mounting bracket, which increases the research and development cost.

[0005] 2. Since the mounting bases for the engine and transmission are fixed, when there are high requirements for the dimensional accuracy of the mounting holes, small adjustments can be made on-site by drilling, while large dimensional adjustments will require on-site recutting and welding, which will increase costs and affect the research and development progress.

[0006] 3. The base is slightly weak and not stable enough when the powertrain is being adjusted in place. At the same time, its rigidity cannot meet the requirements of the powertrain loading test.

[0007] In view of this, the present invention is hereby proposed. Summary of the Invention

[0008] To address the shortcomings of existing powertrain assembly brackets, this invention provides a wide-range adjustable powertrain assembly bracket that meets the requirements for powertrain assembly, dimensional inspection, and on-site functional debugging for various vehicle models, thereby improving testing efficiency while reducing research and development costs.

[0009] Specifically, the present invention provides the following technical solution:

[0010] A wide-range adjustable powertrain assembly bracket includes a base (1) and several movable engine mounting block assemblies (2);

[0011] Each of the movable engine mounting block assemblies (2) includes an engine mounting bracket (4), a concave slider (5), an engine track slider (6), and an upper concave slider (7); the engine mounting bracket (4) is mounted on the top of the concave slider (5); the concave slider (5) and the upper concave slider (7) are fixedly connected vertically relative to each other; the engine track slider (6) is a rectangular hollow frame, installed between the concave slider (5) and the upper concave slider (7), and slides with the concave slider (5) and the upper concave slider (7) in the x-direction (the x-direction is the length direction of the engine track slider and the transmission device track slider);

[0012] The base (1) is provided with a number of first sliding support rails on its top, and each first sliding support rail has two horizontally parallel first track sliders (11); each movable engine mounting block assembly (2) is respectively disposed between the two first track sliders (11) of a first sliding support rail, and the two ends of the engine track slider (6) are respectively slidably engaged with the two first track sliders (11) in the y direction (the y direction is the length direction of the first track slider and the second track slider).

[0013] Preferably, the top of the engine mounting bracket (4) is provided with a threaded mounting hole for fixing the engine.

[0014] The bottom of the engine mounting bracket (4) is fixedly connected to the concave slider (5) by the first connecting bolt (8);

The lower concave slider (5) and the upper concave slider (7) have first bolt holes at the same horizontal position as the waist-shaped holes. The third connecting bolt (10) passes through the first bolt holes and extends into the waist-shaped holes. The movement of the engine mounting bracket in the x-direction is achieved by moving the third connecting bolt on the waist-shaped holes. The waist-shaped holes and the third connecting bolt in this invention have two main functions: first, positioning; when moved to the appropriate position, the slider can be fixed by the third connecting bolt to prevent displacement; second, the upper and lower concave sliders can be fixed on the engine slide rail by the third connecting bolt, which facilitates installation and reduces sliding resistance.

[0017] Preferably, the first track slider (11) is a rectangular hollow frame;

[0018] In each set of first sliding support rails, the upper and lower parts of the two first track sliders (11) on opposite sides are respectively machined with waist-shaped holes that are consistent with their length direction. The two ends of the engine track slider (6) are provided with second bolt holes at the same horizontal position as the waist-shaped holes. The fourth connecting bolt (12) passes through the second bolt hole and extends into the waist-shaped hole. The movement of the engine mounting bracket in the y direction is realized by the movement of the fourth connecting bolt (12) on the waist-shaped hole.

[0027] The adjusting shim (20) is installed between the transmission device mounting bracket (13) and the transition mounting plate (14), and the adjusting shim (20) has a fifth bolt hole for the five connecting bolts (16) to pass through. When replacing transmission devices of different heights, the present invention can add an adjusting shim (20) between the transmission device mounting bracket (13) and the transition mounting plate (14). By changing the thickness of the adjusting shim (20), the height of the center horizontal plane of the transmission device can be adjusted, thereby adapting to transmission devices of different heights.

[0028] Preferably, the second track slider (18) is a rectangular hollow frame;

[0029] In each set of second sliding support rails, the upper and lower parts of the two second track sliders (18) on opposite sides are respectively machined with waist-shaped holes that are consistent with their length direction. The two ends of the transmission device track slider (15) are provided with sixth bolt holes at the same horizontal position as the waist-shaped holes.

Each set of first sliding support rails has two horizontally parallel first track sliders (11). The first track sliders (11) are rectangular hollow frames with a length of 700mm. Each movable engine mounting block assembly (2) is respectively set between the two first track sliders (11) of a set of first sliding support rails.

[0051] During powertrain assembly and debugging, the distance between the engine mounting brackets (4) is adjusted according to the size of the engine in different models. The distance between the front and rear of the engine mounting brackets (4) is adjusted by sliding the engine mounting brackets (4) on the engine track slider (6), thereby adapting to engines of different sizes.
