Embodiment Construction

[0023] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0024] The present invention is a variable control mechanism of a hydraulic inclined axis motor, such as Figure 1-Figure 6 As shown, it includes a proportional solenoid valve control part and a motor cover variable mechanism realization part. The change of the current of the solenoid valve 5 controls the movement of the spool 6, and the opening and closing control oil circuit controls the swing of the slide rod 13 inside the motor cover 1. Connect the motor valve plate and the cylinder body to swing to realize the displacement change.

[0025] The proportional solenoid valve control part includes a solenoid valve block 3 , an adjusting screw rod 4 , a solenoid valve 5 , a valve core 6 and a valve sleeve 7 .

[0026] The motor cover variable mechanism realization part includes motor cover 1, one-way throttle valve 2, first spring...

Abstract

The invention discloses a hydraulic tilting-axis motor variable control mechanism which is characterized by comprising a motor cover. A sliding rod is arranged inside the motor cover. One end of the sliding rod is connected with a piston. The other end of the sliding rod is connected with one end of a first spring base through a third spring. The other end of the first spring base is arranged inside an electromagnetic valve block to be connected with one end of a valve core. The valve core is arranged inside a valve sleeve. The valve sleeve is arranged inside the electromagnetic valve block. An adjusting screw rod is arranged on the side face of the electromagnetic valve block. The electromagnetic valve block is connected with an electromagnetic valve. The motor cover is internally connected with one end of a second spring base through a second spring. The other end of the second spring base is connected with a base of the first spring base through a first spring. The hydraulic tilting-axis motor variable control mechanism has the advantages of being flexible in reaction, steady in control, capable of achieving displacement stepless changes and the like.

Description

technical field [0001] The invention relates to a variable control mechanism of a hydraulic inclined-axis motor, which is suitable for driving mechanical walking and driving industrial devices, and belongs to the technical field of hydraulic motors. Background technique [0002] Most of the existing inclined-axis motors on the market are fixed-quantity motors, and some variable-variable inclined-axis motors are mostly variable, which cannot realize stepless displacement control or variable control is unstable. Due to the complex changes in the working environment of the motor, as the current society has higher and higher requirements for energy conservation and environmental protection, hydraulic motors should also have good variable control characteristics to adapt to changing environmental requirements, save energy, reduce emissions, and improve efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydr...
