A dynamic inertial guidance control device

Abstract

The invention provides a dynamic-inertia guiding control device, which includes a cylinder body, a piston and a main spiral tube. The piston divides the inner chamber of the cylinder body into an upper chamber and a lower chamber. Spiral tube; the piston includes a piston body, a mass block and a spiral groove; the piston body is provided with an inner cavity, and the inner cavity communicates with the upper cavity and the lower cavity respectively; the two ends of the mass block are respectively installed by elastic devices In the inner cavity; the inside of the piston body is provided with a number of spiral grooves uniformly distributed along the inner cavity, a part of the spiral grooves communicates with the upper cavity and the inner cavity, and the other part of the spiral grooves communicates with the lower cavity and the inner cavity; The mass block selectively connects or blocks several of the spiral grooves with the inner cavity according to changes in acceleration. The invention realizes the identification and follow-up control of the acceleration directions of the two ends, so that the acceleration-based semi-active control method can be passively realized without relying on the input of external energy, and the device has a high 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
