[0033] See also Figures 1 to 5 , the present application provides an embodiment of a single generator bracket at the front end of an engine, the embodiment comprising:
[0034] The present application provides a single generator bracket at the front end of an engine, and the single generator bracket at the front end of the engine comprises:
[0035] A support body 1, wherein the support body is provided with a generator support 2, a lifting lug 3 and an engine connection hole group 4;
[0036] The generator bracket 2 is arranged at the front end of the bracket body 1, and the generator bracket 2 is provided with a generator mounting hole group 5, and the generator mounting hole group 5 is used to cooperate with the generator bracket 1 to fix the generator;
[0037] The engine connection hole group 4 is used to fix the bracket body 1 on the engine;
[0038] The lifting lug 3 is used to cooperate with external facilities to install the engine in a working scene.
[0039] Specifically, the single generator bracket at the front end of the engine provided in the present application is used to compactly connect and install a generator on the engine in actual application scenarios. The bracket body 1 of the single generator bracket at the front end of the engine is formed in one piece, wherein the bracket body 1 is designed with support columns for support, and the support columns are connected by a lighter and thinner design, so that the bracket body 1 can ensure the physical strength for actual use while being lightweight.
[0040] In a diesel engine, the generator is usually directly connected to the engine, using the engine's rotation to drive the generator to generate electricity. As a means of public transportation, buses need to provide a variety of equipment and services, such as lighting, air conditioning, audio, access control, etc. These equipment and services consume a lot of electricity during the vehicle's operation. In order to ensure the normal operation of the vehicle and the comfort of passengers, buses need to be equipped with large-flow generators.
[0041] The large flow generator can provide higher power generation capacity and more stable power output to meet various power needs during the driving of the bus. This generator is usually connected to a diesel engine or a gas engine, and uses the rotation of the engine to drive the generator to generate electricity. In this application, the generator corresponding to the bracket body 1 is a 240A generator, which is a generator with a large capacity and can meet a large power demand.
[0042] Arranging a 240A generator can reduce the need to arrange multiple generators. The gear train connecting a single generator to the engine is simple, and a multi-V belt can be used to connect the gear train, reducing the generator pulley and thus improving transmission efficiency.
[0043] Optionally, a protrusion 6 is provided at the bottom of the bracket body 1, and the protrusion 6 is used to fix the engine wiring harness bracket.
[0044] The engine wiring harness bracket is generally used to fix and support the wiring harness. In addition, the engine wiring harness bracket can protect and isolate the wiring harness after fixing and supporting the wiring harness, so that the wiring harness can maintain the current arrangement and layout, and when the wiring harness is affected by the vibration and noise during engine operation, it can reduce the impact of vibration and noise on the wiring harness.
[0045] Optionally, the engine connection hole group 4 is arranged below the rear end of the bracket body 1, and the engine connection hole group 4 is provided with 6 engine connection holes, and the 6 engine connection holes are arranged around the bracket connection hole 7.
[0046] The engine connection control group is used to connect the bracket body 1 to the engine. In actual situations, the engine and generator of the diesel engine are connected through mechanical energy, that is, the position layout needs to be carried out by satisfying the gear train layout. However, the present application defines the position relationship between the engine and the generator through the bracket body, making the diesel engine front end gear train layout more compact, thereby meeting the layout requirements of the high-power generator.
[0047] Optionally, the bracket connecting hole 7 is used to connect and support other brackets.
[0048] Specifically, the other brackets described here are not other identical generator support brackets, but other brackets that meet other assembly or configuration requirements of the engine, such as gear train brackets, etc., which are not specifically limited here.
[0049] Optionally, the generator mounting hole group 4 is provided with four generator mounting holes, and the four generator mounting holes are respectively provided at four vertices of the generator bracket.
[0050] Specifically, the generator needs to be firmly connected to the bracket body 1, and the generator bracket 1 is combined with the generator to fix the generator on the generator mounting hole group through track bolts. It is explained that in this application, the generator is fixed to the four vertices of the generator bracket 2 through four track bolts, so that the generator is connected to the generator bracket 2.
[0051] Optionally, the ear 3 is formed integrally with the bracket body 1. The ear 3 is arranged at the upper end of the bracket body 1.
[0052] The lifting ear 3 can be cancelled according to the engine requirements during actual production. For example, if the engine body already exists or other brackets have lifting ears, the lifting ear 3 can be simplified as needed during actual production. However, because the lifting ear 3 and the bracket body 1 are integrally formed, the lifting ear 3 must be cancelled during actual production if it needs to be cancelled, and cannot be cancelled after the production is completed.
[0053] The generator bracket 2 is provided with a support assembly 8 , and the support assembly 8 is perpendicular to the bracket body 1 .
[0054] The support assembly 8 is used to support the generator bracket 2. Since the bracket body 1 of the present application is designed to be flat in order to meet the requirements of lightweight, but in order to stably fix the generator, the generator must be fixed at multiple points, so there is a need to extend and support the generator bracket 2 through the support assembly 8.
[0055] Optionally, the bottom end of the bracket body 1 widens from the engine connection hole group 4 toward the generator bracket 2 and presents an irregular trapezoidal shape.
[0056] Specifically, the generator bracket needs to be wide enough to stably support the generator, but in the actual assembly process, it needs to be as lightweight as possible. The irregular trapezoid presented in this application balances these two disadvantages to a certain extent.
[0057] It can be seen from the above technical solutions that this application has the following advantages:
[0058] The present application concentrates the weight of the generator on the bracket, which has a strong load-bearing capacity and can bear the weight of a high-power generator. The weight of the generator is concentrated on the bracket body by installing the generator on the bracket body and connecting the engine through the bracket body. The bracket connection makes the spatial arrangement of the engine and the generator more compact, reducing the arrangement of multiple generators. The wheel train is simple and uses a multi-V belt to connect the wheel train, which can reduce the size of the generator pulley, thereby increasing the transmitted power and meeting the layout requirements of the high-power generator.
