Problems solved by technology

Due to structural limitations, both the rotary vane damping scheme and the torsion-adjustable rotary damping scheme in the literature can only achieve damping loading in reciprocating rotation with a rotation angle of less than 360°, and the rotary hydraulic pump + damping hole proportional servo control scheme is not compact enough. And the cost of proportional valve control is high

Embodiment Construction

[0022] Combine Figure 1-Figure 4 As shown, the present invention is further described as follows: An electronically controlled variable damping rotary hydraulic damper, including 3 blades, a valve body 4, a valve core 3, a shaft 6, a housing 5, an end cover 9, a compression spring 8, and a motor The 1, 3 blades are the first blade 7, the second blade 12, and the third blade 10. The end cover 9 is connected with the housing 5, and the shaft 6 is located in the cavity between the end cover and the housing. The input of the shaft 6 End protrudes from the end cap,

[0023] A guide rail 11 is machined on the housing and the bottom cover. The minimum diameter of the guide rail 11 is equal to the outer diameter of the shaft, and the maximum diameter of the guide rail 11 is equal to the diameter of the inner cavity of the housing. The maximum diameter of the guide rail is greater than 120°. The maximum diameter arc and the minimum diameter concentric arc are connected by a transition cu...

Abstract

The invention relates to an electronic control variable-damping rotation hydraulic damper which comprises a motor, an outer shell, a blade, a valve element, a valve body, a shaft, a spring, a cover plate and the like. Due to the fact that a guide groove is formed in the middle shaft of the variable-damping rotation hydraulic damper, a guide rail is arranged on the shell, the blade automatically moves transversely in the radial direction along with the guide rail during rotation, the volume of driven liquid is changed, the liquid flows in a circulated manner through the valve element, and the function that the rotation angle of the damper is unlimited is achieved; and the valve element is driven by a step motor to rotate, so that the size of the drift diameter of a runner composed of the valve element and the valve body is variable, and the function of being adjustable in rotation damping is achieved.

Description

Technical field [0001] The invention relates to a hydraulic damper, in particular to an electronically controlled damping rotary hydraulic damper, and belongs to the fields of automobiles and electromechanics. Background technique [0002] At present, hydraulic dampers are widely used in machinery, automobile and other industries to alleviate the impact caused by mechanical vibration. The common hydraulic dampers in automobiles are mainly cylindrical hydraulic dampers with linear displacement changes, which are difficult to apply in rotating machinery. In order to increase the damping of the mechanism's rotation process, the researchers proposed a magnetorheological solution and a rotating hydraulic damping solution. Magnetorheological solutions are costly due to complex control. The common hydraulic damping schemes mainly include rotary vane damping scheme, rotary hydraulic pump + orifice proportional servo control scheme, torque adjustable rotary damping scheme, etc. Due to ...
