Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to an integrated bearing platform for a two-cylinder diesel engine. Background Art

[0002] Two-cylinder diesel engines operate at high speeds, and crankshaft speed monitoring is crucial for the proper functioning of modern automotive engines. It not only impacts engine performance but also the vehicle's economy and environmental friendliness. Furthermore, engines require oil at the appropriate pressure and temperature to reduce friction and wear. Furthermore, combustion within the diesel engine generates significant heat, which requires coolant to dissipate and cool the engine.

[0003] Therefore, to ensure the normal operation of the diesel engine, it is necessary to design components such as the water pump, oil pump, oil pressure regulator, oil lubrication, engine speed monitoring, and various transmission gear pairs. Existing layouts often use a decentralized, independent arrangement of multiple brackets, interconnected by external piping.

[0004] For example, the Chinese patent with announcement number CN204024812U discloses a multi-purpose two-cylinder diesel engine, in which multiple independent supports require a large number of screw holes on the diesel engine for fastening the supports. The complex structure poses a risk of bolt loosening, and the multiple supports require more space for installation, which is not conducive to the compact layout of the entire machine. In addition, the dispersed components are connected to each other by external pipelines, which will inevitably use a large number of pipeline components, resulting in a complex structure and the risk of pipeline leakage.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific implementations, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined unless they conflict.

[0035] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0036] like Figures 1 to 4 As shown, an integrated load-bearing platform for a two-cylinder diesel engine includes a platform body, a water circuit composed of embedded pipes, and an oil circuit composed of embedded pipes. The water circuit and the oil circuit are both arranged on the platform body, wherein one end surface of the platform body is provided with a water pump mounting port 1, a speed sensor mounting port 2, and a crankshaft port 3;

[0037] The water pump installation port 1 is provided on the upper part of the platform body and is used to install the water pump 13;

[0038] The crankshaft port 3 is provided at the lower part of the platform body and is used to install the crankshaft 11;

[0039] The speed sensor installation port 2 is provided between the water pump installation port 1 and the speed sensor installation port 2 and is used for installing the speed sensor;

[0040] The side of the platform body is provided with an oil channel 4 for the oil pump and an installation port 5 for the oil pressure regulating valve;

[0041] The oil pump oil passage 4 is arranged above the oil pressure regulating valve installation port 5 .

[0042] The purpose of this design is to arrange the water pump, oil pump, oil lubrication, engine speed monitoring and various transmission gear pairs on a supporting platform, and seal the cylinder head to achieve a compact overall layout, thereby reducing the use of parts and reducing the risk of leakage in various pipelines. By arranging the water pump installation port and the body water inlet connected to the water channel on the platform body, effective cooling of the diesel engine is achieved, thereby improving the engine's working efficiency and service life. At the same time, the integrated design makes maintenance work easier, because the interrelated components and pipelines are pre-configured on a platform, reducing the disassembly and diagnosis time during maintenance.

[0043] At the same time, in this embodiment, a diesel engine oil inlet 7 is provided on the oil pump oil channel 4, and the diesel engine oil inlet 7 is connected to the oil circuit. A cylinder water inlet 6 is provided on one side of the water pump mounting port 1, and the cylinder water inlet 6 is connected to the water circuit. The water pump 13 pumps the coolant into the cylinder water inlet 6, and enters the cylinder of the diesel engine through the cylinder water inlet 6 for cooling. An oil pump oil inlet 9 and an oil lubrication spray hole 10 are provided at the bottom of the platform body. The oil pump oil inlet 9 is connected to the high and low pressure oil chambers 8 of the oil pump, and the oil lubrication spray hole 10 is connected to the low pressure oil chamber of the high and low pressure oil chambers 8 of the oil pump. An oil pump pressure regulating valve 15 is installed on the oil pressure regulating valve mounting port 5.

[0044] In this way, in the specific implementation, the crankshaft 11 rotates as a power source, driving the oil pump 12 to pressurize the oil through the oil circuit, entering the oil pump high and low pressure oil chambers 8 from the oil pump oil inlet 9, and then entering the cylinder through the cylinder main oil channel port 7. At the same time, when the oil pressure is too high, the oil pressure can be adjusted through the oil pump pressure regulating valve 15 to discharge excess oil.

[0045] To lubricate the gears and transmission chain, the oil lubrication nozzle 10 communicates with the low-pressure oil chamber of the oil pump's high- and low-pressure oil chambers 8. When the oil pump 12 is operating, it sprays oil from the low-pressure oil chamber, splashing and lubricating the gears and transmission chain. This invention makes the two-cylinder diesel engine more compact and minimizes the use of external piping components. This also reduces the potential for pipeline leakage during operation, thereby improving overall engine reliability.

[0046] Furthermore, in this embodiment, an oil pump high and low pressure oil chamber 8 is provided in the crankshaft port 3, and the oil pump high and low pressure oil chamber 8 is provided around the crankshaft 11, and an oil pump 12 is provided on the oil pump high and low pressure oil chamber 8;

[0047] The crankshaft 11 is sleeved with a crankshaft gear;

[0048] The crankshaft gear can drive the inner rotor of the oil pump 12 to rotate, and a water pump pulley is provided on the water pump 13. A crankshaft pulley 14 is provided on the crankshaft 11, and belts are provided on the crankshaft pulley 14 and the water pump pulley, and the crankshaft pulley 14 and the water pump pulley can transmit the power source of the crankshaft 11 to the water pump 13.

[0049] The purpose of this design is that the crankshaft 11 is arranged in the crankshaft port 3 as a power source, and a gear is provided on the crankshaft 11. The oil pump 12 is arranged at the high and low pressure oil chamber 8 of the platform oil pump. The crankshaft gear and the rotor inside the oil pump are driven by the crankshaft, and the power source of the crankshaft 11 can drive the rotation to do work.

[0050] A water pump 13 is mounted on the water pump mounting port 1. A pulley is provided on the water pump 13. A crankshaft pulley 14 transmits the power source of the crankshaft 11 to the water pump 13, driving the water pump 13 to rotate and produce work. When the diesel engine is in operation, coolant flows through the water pump 13 into the cylinder water inlet 6 and flows to the cylinder of the diesel engine for cooling.

[0051] Furthermore, the design of the intermediate transmission gear mounting hole rationally utilizes the structural space at the crankshaft port, while the placement of the oil pump ensures efficient operation of the lubrication system. Furthermore, the oil inlet design simplifies the oil circuit and ensures smooth oil supply. The speed sensor mounting port provides convenient access to the engine control system, enabling real-time monitoring of engine status and providing accurate data to the electronic control unit or management system.

[0052] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
