Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to a motor with anti-air suction function and real-time speed measurement. Background Technology

[0002] In conventional hydraulic steering control systems, the motor is a standalone actuator. Under special operating conditions, the motor is prone to insufficient oil supply, resulting in a suction effect. This suction effect creates a partial vacuum in the oil inlet line and motor chamber. Generally, an anti-vacuum check valve is connected in parallel to the main oil line of the system, that is, the main line connecting the motor's inlet and outlet. Meanwhile, the motor speed is detected by a tachometer, which is inconvenient in actual operation.

[0003] Therefore, it is necessary to develop new types of motors to overcome the above problems. Utility Model Content

[0005] Technical solution: The present invention provides a motor with anti-vacuum function and real-time speed measurement, characterized in that: it includes a motor assembly and a rear cover, the rear cover being connected to an anti-vacuum one-way valve and a speed sensor; the housing of the motor assembly is provided with an oil inlet A port and an oil return port B port, and the housing of the rear cover assembly is provided with an oil inlet A port and an oil return port B port.

[0006] The motor assembly has a front cover with a support bearing, and the motor assembly is directly connected to the rear cover assembly.

[0007] The rear cover assembly includes a rear cover, an anti-vacuum one-way valve, and a speed sensor.

[0008] The rear cover is provided with an insertion hole for installing an anti-vacuum one-way valve.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] This utility model discloses a motor with anti-vacuum function and real-time speed measurement, comprising a motor assembly 1 and a rear cover 4. The rear cover 4 is connected to an anti-vacuum one-way valve 5 and a speed sensor 6. The motor assembly 1 has an oil inlet A port 2 and an oil return B port 3 on its housing, and the rear cover assembly also has an oil inlet A port and an oil return B port on its housing. The front cover of the motor assembly 1 has a support bearing, and the motor assembly 1 is directly connected to the rear cover assembly. The rear cover assembly includes a rear cover 4, an anti-vacuum one-way valve 5, and a speed sensor 6. The rear cover 4 has a mounting hole for the anti-vacuum one-way valve 5 and a mounting hole for the speed sensor 6.

[0017] During use, when the motor stops running, the original high pressure of the oil inlet to the motor becomes low pressure through the anti-vacuum check valve 5. At this time, the oil supply to the motor inlet stops, and the oil is directly replenished from the motor return port through the check valve to prevent the motor from sucking in air (vacuum).

[0018] The speed sensor 6 can detect the motor speed in real time during motor operation, thereby identifying whether the motor oil flow rate meets the requirements.

[0019] This utility model adopts an integrated arrangement of hydraulic components, resulting in a compact installation space. It also utilizes the internal oil chamber of the motor to reduce pipeline connections and facilitates operation.
