Movable inertia guiding control device

Abstract

The invention provides a movable inertia guiding control device which comprises a cylinder block, a piston and a main helical pipe; the piston divides the cavity of the cylinder block into an upper cavity and a lower cavity; the main helical pipe is connected between the upper cavity and the lower cavity; the piston comprises a piston main body, a mass block and a plurality of spiral grooves; a cavity is formed in the piston main body and communicates with the upper cavity and the lower cavity separately; the two ends of the mass block are mounted in the cavity through elastic devices; the spiral grooves uniformly formed along the cavity are formed in the piston main body; a part of spiral grooves communicates with the upper cavity and the cavity; the other part of spiral grooves communicates with the lower cavity and the cavity; and according to variation of the accelerated speed, the mass block selectively enables the spiral grooves to communicate with or block the cavity. The movable inertia guiding control device realizes identification and follow-up control of the accelerated speed directions at two endpoints, so that the semi-active control method based on the accelerated speed is realized passively, and input of external end energy is not needed. In addition, the movable inertia guiding control device is high in degree of integration and is easy to arrange.

Description

technical field [0001] The invention relates to the field of motor vehicle shock absorbers, in particular to a dynamic inertia guidance control device. Background technique [0002] With the development of my country's transportation industry, domestic passenger vehicles are developing in the direction of intelligence, high speed, light weight and cleanliness, and the requirements for energy saving of vehicles are getting higher and higher. With the consolidation of the vehicle suspension structure, the improvement of the comprehensive performance of ordinary passive suspension is approaching the limit, and researchers are gradually turning their attention to semi-active control suspension and active control suspension. However, no matter semi-active control suspension or active control suspension, energy input outside the suspension is required to achieve control, and the development of active suspension is slow because of high energy consumption. [0003] With the develop...

Problems solved by technology

Different from the damper, the force at the two ends of the damper is related to the relative speed of the two ends, while the force at the two ends of the dynamic inertial element is related to the relative acceleration of the two ends, which is different from the speed of motion that is easy to identify the direction. The direction is difficult to be directly identified by the direction of motion of the object, so some "on-off" control methods are difficult to apply to dynamic inertial components in a passive way
