Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, and particularly relates to a bilateral-shaft power hydraulic pump and a hydraulic assembly. Background Art

[0002] A hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission. Driven by an engine or a motor, it sucks oil from a hydraulic oil tank, forms pressurized oil and discharges it to an actuator to drive the actuator. However, existing hydraulic pumps often suffer from insufficient hydraulic oil flow and pressure, and the power carrier often fails to reach an ideal working state. At the same time, existing hydraulic pumps also have insufficient driving force, which further affects work efficiency, especially in the case of being driven by uncontrollable natural forces such as wind power. Content of the Utility Model

[0003] In view of the above problems, the utility model discloses a bilateral-shaft power hydraulic pump and a hydraulic assembly. By setting double inlet and outlet oil circuits, the flow of hydraulic oil can be increased, and strong pressure can be generated to input power to the power carrier to reach an ideal working state. At the same time, by setting bilateral shafts, bilateral drive can be realized to improve the driving force. The design of the bilateral shafts can also connect the main power source on one side and the auxiliary power source on the other side. When the driving force of the main power source is insufficient, the auxiliary power source can assist in supplementing the power, so that the power carrier can continue to operate.

[0004] A bilateral-shaft power hydraulic pump proposed according to the purpose of the utility model includes a hydraulic pump main body, a gear assembly arranged in the hydraulic pump main body, an oil inlet and an oil outlet arranged on the hydraulic pump main body, and a power shaft. The oil inlet and the oil outlet are two groups arranged on the hydraulic pump main body. The power shaft is composed of two shafts respectively arranged on both sides of the gear assembly and connected to the driving gear in the gear assembly.

[0005] Preferably, the oil inlet and the oil outlet are two groups symmetrically arranged on both sides of the gear assembly.

[0006] Preferably, the power shaft includes a main power shaft for connecting the main driving force and an auxiliary power shaft for connecting an auxiliary driving mechanism.

[0007] A hydraulic assembly further disclosed by the utility model includes the above-mentioned bilateral-shaft power hydraulic pump and an auxiliary motor. The output end of the auxiliary motor is connected to the auxiliary power shaft of the bilateral-shaft power hydraulic pump.

[0008] Preferably, a check valve is further arranged between the auxiliary motor and the bilateral-shaft power hydraulic pump.

[0009] Compared with the prior art, the advantages of a bilateral-shaft power hydraulic pump and a hydraulic assembly disclosed by the utility model are:

[0010] (1) By providing a dual inlet and outlet oil circuit in the hydraulic pump of the present utility model, the flow rate of hydraulic oil can be increased, generating a strong pressure to input power to the power carrier to achieve an ideal working state. At the same time, by providing a bilateral shaft, bilateral drive can be realized, improving the driving force.

[0011] (2) With the bilateral shaft design of the hydraulic pump of the present utility model, one side can be connected to the main power source, and the other side can be connected to the auxiliary power source. The external power is connected to the main power source. When the external power is at full load, the hydraulic pump can operate normally. When the external power is insufficient, by connecting the auxiliary power source, power can be supplemented without any impact on the external power, enabling normal operation, so that the power carrier can continue to operate. This device is suitable for harsh environments such as the wild and mountainous areas and can be matched with various hydraulic terminals. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following briefly describes the specific embodiments of the present utility model in conjunction with the drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0017] Figure 1 - Figure 2 Illustrates the preferred embodiments of the present utility model and analyzes them in detail.

[0018] As Figure 1A bilateral-axis power hydraulic pump shown in the figure comprises a hydraulic pump main body, a gear assembly 11 arranged inside the hydraulic pump main body, an oil inlet 12 and an oil outlet 13 arranged on the hydraulic pump main body, and a power shaft. Among them, the oil inlet 12 and the oil outlet 13 are two groups symmetrically arranged on both sides of the gear assembly 11. By setting a double inlet and outlet oil circuit, the flow rate of hydraulic oil can be increased, generating a strong pressure to input into the power carrier to achieve an ideal working state. The power shaft includes a main power shaft 14 for connecting the main driving force and an auxiliary power shaft 15 for connecting an auxiliary driving mechanism. The two power shafts are arranged on both sides of the gear assembly 11 and are both fixedly connected to the driving gear in the gear assembly 11. The bilateral-axis design allows one side to connect to the main power source and the other side to connect to the auxiliary power source. The external power connects to the main power source. When the external power is at full load, the hydraulic pump can work normally. When the external power is insufficient, by connecting to the auxiliary power source, power can be supplemented without any impact on the external power, enabling normal operation, so that the power carrier can run continuously. The gear assembly 11 includes a driving gear and a driven gear. The driving gear rotates driven by the main power shaft 14 and the auxiliary power shaft 15, meshes with the driven gear for transmission, sucks hydraulic oil from the hydraulic oil tank through the oil inlet 12, and conveys it to the driving carrier through the oil outlet 13 after pressurization.

[0019] As Figure 2 As shown in the figure, another hydraulic assembly disclosed by the present utility model comprises the above-mentioned bilateral-axis power hydraulic pump 1, a check valve 2, and an auxiliary motor 3. The output end of the auxiliary motor 3 is connected to the auxiliary power shaft 15 of the bilateral-axis power hydraulic pump 1 through the check valve 2. The setting of the auxiliary motor 3 can supplement power when the external power is insufficient to achieve normal operation, so that the power carrier can run continuously. The setting of the check valve 2 can ensure that the auxiliary motor 3 does not work when the main power source is working normally.

[0020] The above description of the disclosed embodiments enables those skilled in the art to implement and use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit and scope of the present utility model.
