Technical Field
[0001] This utility model relates to the field of engine technology, and in particular to a hydraulic high-torque engine. Background Technology
[0002] In the current technology, the use of energy-saving and emission-reduction technologies in automobile engines on various models, such as increasing the air density in the cylinder or installing fuel injectors inside the cylinder, can make the fuel burn more completely and improve fuel efficiency, but still cannot effectively reduce fuel consumption and carbon emissions.
[0003] Current engines primarily utilize fuel combustion, with thermal efficiencies generally between 30% and 40% (some advanced diesel engines can reach 45%). Excess energy is wasted as waste heat or through friction. The combustion of fossil fuels in internal combustion engines inevitably produces carbon dioxide and harmful substances; although after-treatment technologies can reduce emissions, they cannot eliminate them entirely.
[0004] Therefore, existing engines suffer from high pollution and low power output. Utility Model Content
[0005] The purpose of this utility model is to provide a hydraulic high-torque engine to solve the technical problems of high pollution and low output power in existing engines; the various technical effects of the preferred technical solutions provided by this utility model are described in detail below.
[0006] To achieve the above objectives, the present invention provides the following technical solution: The hydraulic high-torque engine provided by this utility model includes a hydraulic power housing, a hydraulic motor, hydraulic pipes, a Pascal treatment device, and a crankcase, wherein: The Pascal processing device includes a housing, a piston chamber located within the housing, a piston, and a connecting rod. The two ends of the hydraulic pipe are respectively connected to the hydraulic power housing and the corresponding piston chamber. The housing is fixedly connected to the crankcase, and the piston chamber is connected to the crankcase. A crankshaft is rotatably connected inside the crankcase. The two ends of the connecting rod are respectively hinged to the piston and the crankshaft. A crankshaft gear is fixed at the output end of the crankshaft and is located outside the crankcase. The hydraulic motor is located on the corresponding hydraulic pipeline and is used to pressurize the hydraulic oil in the hydraulic power housing to the corresponding piston chamber, thereby enabling the piston to move within the corresponding piston chamber.
[0007] Preferably, the piston is arranged perpendicular to the crankshaft.
[0008] Preferably, the housing is a cylindrical structure, and there are two or more housings. The number and position of the housing, the piston, the hydraulic pipe, the connecting rod and the piston chamber are arranged in a one-to-one correspondence, and the housings are arranged at intervals along the axial direction of the crankshaft. Preferably, there are two or more piston chambers, and the number and position of the piston, hydraulic pipe, and connecting rod correspond one-to-one with the number of piston chambers. Different connecting rods are hinged to different sections of the crankshaft. When there are two pistons and two hydraulic pipes, when one piston extends in the corresponding piston chamber, the other piston retracts in the corresponding piston chamber, thereby causing the two connecting rods to drive the crankshaft to rotate synchronously.
[0009] Preferably, the hydraulic high-torque engine further includes a speed-increasing device, which is connected to the crankshaft gear transmission and is used to increase the rotational speed of the crankshaft gear.
[0010] Preferably, the hydraulic high-torque engine further includes a speed increaser, a speed increaser input shaft rotatably connected to the speed increaser, and a speed increaser output shaft, wherein: The speed increaser input shaft and speed increaser output shaft are driven by a gear set. The speed increaser input shaft is provided with an input gear that meshes with the crankshaft gear, and the speed increaser output shaft is provided with an output gear.
[0011] Preferably, the hydraulic pipe is a hydraulic hose, and the hydraulic pipe is provided with a valve body for controlling the connection or blockage between the hydraulic power housing and the piston chamber.
[0012] Preferably, a pressure gauge is provided on the hydraulic power housing, and the pressure gauge is used to detect the pressure in the corresponding hydraulic pipe.
[0013] Preferably, the bottom of the hydraulic power housing is provided with a mounting plate, and the mounting plate is provided with multiple fixing holes.
[0014] Preferably, a fixing plate is fixedly connected to the bottom of the crankcase, and the fixing plate is provided with multiple locking holes.
[0015] The hydraulic high-torque engine provided by this utility model has the following advantages compared with the prior art: the hydraulic motor pressurizes the hydraulic oil and then inputs it into the piston chamber through the hydraulic pipe. The transmission structure of the piston, connecting rod, and crankshaft converts hydraulic energy into mechanical energy, avoiding the fuel combustion process and reducing environmental pollution. Utilizing Pascal's principle, the high-pressure hydraulic energy is efficiently converted into a powerful linear thrust of the piston, which is then converted into rotary output through the crankshaft gear on the crankshaft. Compared with the huge energy loss caused by the multi-stage energy conversion of traditional internal combustion engines, this hydraulic high-torque engine has higher energy conversion efficiency and can achieve high torque output. Due to the improved energy utilization efficiency, this hydraulic high-torque engine consumes less energy when outputting the same power. Attached Figure Description

[0022] This utility model provides a hydraulic high-torque engine that can achieve high torque output and consume less energy when outputting the same power.
[0023] The following is combined with Figure 1 and Figure 2 The technical solution provided by this utility model will be described in more detail.
[0024] like Figure 1 and Figure 2 As shown, the hydraulic high-torque engine provided by this utility model includes a hydraulic power housing 1, a hydraulic motor 2, a hydraulic pipe 4, a Pascal treatment device 5, and a crankcase 6. The Pascal treatment device 5 includes a housing 50, a piston chamber 51 located within the housing 50, a piston 52, and a connecting rod 18. Both ends of the hydraulic pipe 4 are in a conductive state with the hydraulic power housing 1 and the corresponding piston chamber 51, respectively. The housing 50 is fixedly connected to the crankcase 6, and the piston chamber 51 communicates with the crankcase 6. A crankshaft 7 is rotatably connected within the crankcase 6. Both ends of the connecting rod 18 are hinged to the piston 52 and the crankshaft 7, respectively. A crankshaft gear 8 is fixedly attached to the output end of the crankshaft 7 and is located outside the crankcase 6. The hydraulic motor 2 is located on the corresponding hydraulic pipe 4 and is used to pressurize the hydraulic oil in the hydraulic power housing 1 to the corresponding piston chamber 51, thereby enabling the piston 52 to move within the corresponding piston chamber 51.
[0025] The hydraulic power housing 1 serves as a hydraulic oil tank, used to store the working medium, namely hydraulic oil. The hydraulic oil can be a conventional mineral oil-based hydraulic oil. The hydraulic motor 2 is mounted on the hydraulic power housing 1, its oil inlet communicating with the internal space of the housing 50, and its high-pressure oil outlet serving as the output end of the entire hydraulic power unit.
[0026] The hydraulic motor 2 can be a fixed or variable displacement gear pump, vane pump, or piston pump driven by an external power source. For example, it can pressurize hydraulic oil to a working pressure range of 10 MPa to 35 MPa.
[0027] To monitor the system's operating status in real time, a pressure gauge 3 is installed on the hydraulic pipe 4. This pressure gauge 3 is used to visually reflect the current operating pressure of the system, thereby facilitating operators to monitor the system load and make necessary adjustments to ensure the safe and stable operation of the system.
[0028] See Figure 1 Hydraulic pipe 4 is a high-pressure hydraulic hose. One end of it is connected to the oil outlet of hydraulic power housing 1, and the other end is connected to the oil inlet of the corresponding housing 50. It can withstand the high pressure of the system and has good flexibility, which facilitates the layout and connection between different components.
[0029] The piston 52 is a cylindrical component, usually made of high-strength aluminum alloy or cast iron. It has several annular grooves on its outer circumference to install piston 52 rings and guide rings. The piston 52 rings are used to form a dynamic seal between the piston 52 and the inner wall of the housing 50 to prevent leakage of high-pressure hydraulic oil in the piston chamber 51.
[0030] See Figure 2 The connecting rod 18 has a large end and a small end. The small end is hinged to the piston 52 via a piston pin, while the large end is hinged to the crankshaft 7 via a bearing bush. The crankshaft 7, as the core rotating component of the engine, is typically forged from ductile iron or alloy steel and includes a main journal for support and a crank pin for connecting the connecting rod 18. The crankshaft 7 is supported on the crankcase 6 by main bearings. The crankcase 6 is a robust housing 50, typically made of cast iron or cast aluminum, which not only provides space and support for the crank-connecting rod 18 mechanism but also stores lubricating oil for lubricating the main bearings of the crankshaft 7, the connecting rod 18 bearings, and other moving parts.
[0031] As an optional implementation, see Figure 2 As shown, piston 52 is positioned perpendicular to crankshaft 7. Piston 52 converts linear motion into rotational motion of crankshaft 7 via connecting rod 18.
[0032] As an optional implementation, see Figure 1As shown, the housing 50 is a cylindrical structure, and there are two or more housings 50. The number and position of the housing 50, piston 52, hydraulic pipe 4, connecting rod 18 and piston chamber 51 are arranged in a one-to-one correspondence. The housings 50 are arranged at intervals along the axial direction of the crankshaft 7.
[0033] As an optional implementation, see Figure 1 and Figure 2 As shown, there are two or more piston chambers 51. The number and position of pistons 52, hydraulic pipes 4, and connecting rods 18 correspond one-to-one with the number and position of piston chambers 51. Different connecting rods 18 are hinged to different sections of crankshaft 7. When there are two pistons 52 and hydraulic pipes 4, when one piston 52 extends in the corresponding piston chamber 51, the other piston 52 retracts in the corresponding piston chamber 51, so that the two connecting rods 18 drive the crankshaft 7 to rotate synchronously.
[0034] See Figure 2 As shown, this embodiment has two piston chambers 51. When hydraulic oil is sent into the first piston chamber 51, the first piston 52 is pushed to perform a power stroke, driving the crankshaft 7 to rotate via the corresponding connecting rod 18. At this time, due to the phase setting of the crankshaft 7, the second piston 52 is in the return stroke. After the crankshaft 7 rotates 180 degrees, high-pressure hydraulic oil is sent into the second piston chamber 51, causing its piston 52 to perform a power stroke, continuing to drive the crankshaft to rotate via another connecting rod 18, while the first piston 52 enters the return stroke.
[0035] The aforementioned structure enhances the engine's performance and applicability, making it particularly suitable for applications requiring high levels of operational smoothness and continuous power.
[0036] To adapt to certain applications requiring high speeds, this embodiment further includes a speed increaser 11 as a speed increaser device to increase the speed of the crankshaft gear 8.
[0037] As an optional implementation, see Figure 1 As shown, the hydraulic high-torque engine also includes a speed increaser 11, a speed increaser input shaft 10 rotatably connected to the speed increaser 11, and a speed increaser output shaft 12. The speed increaser input shaft 10 and speed increaser output shaft 12 are driven by a gear set. The speed increaser input shaft 10 is equipped with an input gear 9, which meshes with a crankshaft gear 8. The speed increaser output shaft 12 is equipped with an output gear 13, which is used to connect to the transmission system of an external load. In this embodiment, the speed increaser input shaft 10 and speed increaser output shaft 12 are driven by a gear set. Speed increase transmission can be achieved using existing planetary gear speed increase devices, etc. The speed increaser 11 is a conventional structure in the art and will not be described in detail here, such as the speed increase mechanism and speed increaser 11 disclosed in patent publication number CN223164945U.
[0038] As an optional implementation, the hydraulic pipe 4 is provided with a valve body (not shown) for controlling the connection or blockage between the hydraulic power housing 1 and the piston chamber 51.
[0039] When the valve body is opened, the hydraulic pipe 4 connects the hydraulic power housing 1 with the corresponding piston chamber 51. When the valve body is closed, the hydraulic power housing 1 is blocked from the corresponding piston chamber 51, and the oil supply to the piston chamber 51 is stopped.
[0040] The complete working process of the engine in this embodiment is described below: See Figure 1 , Figure 2 After the external power supply is turned on, the hydraulic motor 2 in the hydraulic power unit begins to rotate, drawing in hydraulic oil from the hydraulic power housing 1 and pressurizing it, then pumping out a stable high-pressure hydraulic fluid through the oil outlet. This high-pressure hydraulic fluid is transported to the piston chamber 51 of the Pascal treatment device 5 via the hydraulic pipe 4. Subsequently, according to Pascal's principle (F=P×A), the high-pressure hydraulic fluid entering the piston chamber 51 applies a uniform and enormous pressure to the effective pressure-bearing surface of the piston 52, thereby generating a powerful linear thrust. Under the action of this thrust, the piston 52 moves linearly along the axial direction within the piston chamber 51, which is the power stroke. The linear motion of the piston 52 is then transmitted to the crankshaft 7 through the connecting rod 18 hinged to it, and under the constraint and transmission of the connecting rod 18, it is precisely converted into the continuous rotational motion of the crankshaft 7. After piston 52 completes its power stroke, its return stroke can be achieved by the inertia of crankshaft 7 rotation, the power of other cylinders in the multi-cylinder structure, or by introducing a low-pressure return oil circuit. As existing mature technologies, they will not be elaborated here. Accordingly, see Figure 1 , Figure 2 The rotational motion of crankshaft 7 is output outward through crankshaft gear 8 at its end. This crankshaft gear 8 meshes with the input gear 9 of speed increaser 11, thereby transmitting power to speed increaser 11. Finally, the gear set within speed increaser 11 speeds up the input low-speed, high-torque power, converting it into higher-speed power, which is then output outward through speed increaser output shaft 12 and speed increaser 11 output gear 13 to drive external equipment. This completes a full and efficient energy conversion and regulation process from hydraulic energy to linear mechanical energy, then to low-speed, high-torque rotary mechanical energy, and finally to high-speed rotary mechanical energy.
[0041] As an optional implementation, see Figure 1 As shown, the bottom of the hydraulic power housing 1 is provided with a mounting plate 14, and the mounting plate 14 is provided with multiple fixing holes 15. Screws or bolts and other locking components pass through the fixing holes 15 to fix the hydraulic power housing 1 to the equipment to be installed, which facilitates the fixation of the equipment.
[0042] As an optional implementation, see Figure 1As shown, a fixing plate 16 is fixedly connected to the bottom of the crankcase 6, and the fixing plate 16 is provided with multiple locking holes 17. Screws or bolts and other locking components pass through the locking holes 17 to fix the crankcase 6 to the equipment to be installed, which facilitates the fixation of the equipment.
[0043] When installing the engine, all parts of the engine can be firmly fixed to the equipment frame directly through the above-mentioned mounting holes and fixing holes 15 using high-strength bolts. The installation process is simple, quick, and has high positioning accuracy.
