Detailed description of the invention
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, a kind of its detailed description of the invention of steering swivel system noise-reductino vibration-damping device proposed according to the present invention, step, structure, feature and effect thereof are described in detail.
Referring to shown in Fig. 2, is the schematic diagram of the preferred embodiment of a kind of steering swivel system noise-reductino vibration-damping device of the present invention.Steering swivel system noise-reductino vibration-damping device of the present invention is installed on hydrostatic steering system, and it forms primarily of vibration sensor 7, control unit 8 and steering oil pipe valve 9.Wherein, what vibration sensor 7 was installed on hydrostatic steering system turns on high pressure fuel pipe 2, detects Vibration Condition.Control unit 8 is electrically connected with vibration sensor 7, and the vibration signal detected is sent to control unit 8 by vibration sensor 7.Steering oil pipe valve 9 is installed on and turns on high pressure fuel pipe 2, be electrically connected with control unit 8, control unit 8 controls according to the vibration signal received the size that steering oil pipe valve 9 changes the cross section that it passes through for fluid, thus changes the dynamic speed of diverted flow, and then changes the frequency of its liquid stream.
Vibration sensor 7 of the present invention is installed on the one end turning to high pressure fuel pipe 2, and steering oil pipe valve 9 is installed on the other end turning to high pressure fuel pipe 2.As shown in Figure 2, vibration sensor 7 is installed on the one end turning to high pressure fuel pipe 2 to be connected with the power steerig pump 4 of hydrostatic steering system, and steering oil pipe valve 9 is installed on the one end turning to high pressure fuel pipe 2 to be connected with the deflector 3 of hydrostatic steering system.
The present invention can not install noise reduction bar turning to the inside of high pressure fuel pipe 2, is provided with drive motor in steering oil pipe valve 9, drives the action of steering oil pipe valve 9, change the size in the cross section that it passes through for fluid by drive motor.
The working process of steering swivel system noise-reductino vibration-damping device of the present invention is described below:
When be installed on hydrostatic steering system turn to the vibration sensor 7 on high-pressure rubber pipe 2 violent vibration to be detected time, send vibration signal to control unit 8, control unit 8 changes the size in the cross section that it passes through for fluid by controlling steering oil pipe valve 9 according to vibration signal, thus change the dynamic speed of diverted flow, and then change the frequency of its liquid stream, vibration sensor 7 continues to detect steering oil pipe, if detect that the high vibration of steering oil pipe still exists, continue to send vibration signal to control unit 8, after control unit 8 receives vibration signal, continue to control the size that steering oil pipe valve 9 changes the cross section that it passes through for fluid, until steering oil pipe no longer high vibration, now vibration sensor 7 no longer detects violent vibration, no longer send vibration signal to control unit 8, control unit 8 no longer action, steering oil pipe valve 9 will keep the size in the cross section now passed through for fluid.
