Technical Field

The invention relates to the field of engineering vibration reduction and vehicle suspension, in particular to an anti-impact inertial container based on coaxial series connection of a flywheel and a spring.

Background

With the continuous development and improvement of automobile manufacturing technology, people have higher and higher requirements on the riding comfort of automobiles, and the problem of automobile vibration is also concerned by more people. The automobile suspension is used as a main vibration damping system and plays an important role in the running smoothness, the operation stability and the riding comfort of a vehicle. However, the performance improvement of the conventional suspension with "spring-damping" as the core element has been gradually trapped in the bottleneck. The addition of the inertial container constructs a new suspension system with an inertial container-spring-damping structure, breaks through the form of the traditional suspension system, and provides a new design idea and development direction for the suspension system.

The inerter is a mechanical device with two terminals and has the characteristics of phase advance, high frequency passing and low frequency blocking. The form and variety of inerter vessels has been rapidly developed since the introduction of the Smith professor of cambridge university, england, 2002. The introduction of the inertial container realizes strict correspondence between the mechanical network and the electronic network, and objectively promotes the development of the mechanical network. At present, the mature realization forms of the inerter comprise a mechanical type and a hydraulic type, the mechanical type comprises a ball screw type and a gear and rack type, and the inerter is structurally characterized in that the mass of a mass block or a flywheel is amplified through a motion conversion mechanism, so that a larger 'virtual mass' is obtained, and the encapsulation of the inertial mass is realized. The inertia container structure with the combination of the spring and the flywheel integrates the advantages of two components, and converts input linear motion into reciprocating rotary motion of the flywheel. When external force is uniformly applied to the thrust cylindrical roller bearing through the hydraulic system, the thrust cylindrical roller bearing compresses the conical spring to drive the flywheel disc to rotate, and the ECU combines basic parameters of the system to enable the flywheel disc to be combined with the volute spiral spring, so that an inertia effect is generated. By adopting an original fusion method, the flywheel disc and the spring element which are connected in series are designed into an equivalent impact-resistant inertial container device, so that the problem of spatial arrangement of the flywheel disc and the spring element can be effectively solved. Because the outer end of the volute spiral spring is tightly pressed in the groove of the fixing ring, when the impact force reaches a critical value, the outer end of the volute spiral spring automatically pops into the next groove, the safety of the system is ensured, and the device can bear large-load impact.

The specific working process is as follows:

when external force uniformly acts on the cylindrical roller thrust bearing A (1) and the cylindrical roller thrust bearing B (12) through a hydraulic system, the cylindrical roller thrust bearing A (1) compresses the conical spring A (2) to drive the flywheel disc A (4) to rotate, and the flywheel disc A (4) rotates to the bottom along the fixed shaft (13) and is connected with the deep groove ball bearing A (6); the thrust cylindrical roller bearing B (12) compresses the conical spring B (11) to drive the flywheel disc B (10) to rotate, and the flywheel disc B (10) rotates to the bottom along the fixed shaft (13) to be combined with the deep groove ball bearing B (9).

A sensor (5) such as a rotating speed sensor collects the information of the rotating speed of the flywheel disc A (4) and transmits the information to an ECU (17), and an execution device (15) enables a deep groove ball bearing A (6) to be unlocked; a sensor (5) such as a rotating speed sensor collects the information of the rotating speed of the flywheel disc B (10) and transmits the information to an ECU (17), and an execution device (15) enables a deep groove ball bearing B (9) to be unlocked; the ECU (17) combines the rotating speed information of the flywheel disc A (4) to issue an instruction to an execution device (15) on the telescopic rod A (3); the fixed ring (16) is combined with the rotating speed information of the flywheel disc B (10) to issue an instruction to an execution device (15) on the telescopic rod B (14); the sensor (5) detects whether the inner end hooks of the telescopic rod A (3) and the right volute spiral spring (7) are on the same horizontal line like a laser sensor. If yes, the execution device (15) enables the telescopic rod A (3) to pop up to drive the right volute spiral spring (7) to rotate, and the sensor (5) is closed like a laser sensor; the sensor (5) such as a laser sensor detects whether the telescopic rod B (14) and the hook at the inner end of the left volute spiral spring (8) are on the same horizontal line. If yes, the execution device (15) enables the telescopic rod B (14) to pop up to drive the left scroll spring (8) to rotate, and the sensor (5) is closed like a laser sensor. The combination of the telescopic rod A (3) and the telescopic rod B (14) with the hooks at the inner ends of the right volute spiral spring (7) and the left volute spiral spring (8) is completed almost at the same time, and the error is within one circle. If the impact force is increased when reaching the critical value, the outer ends of the right scroll spring (7) and the left scroll spring (8) automatically bounce to the next groove, so that the safety of the system is ensured, and the device can bear the impact of large load.

The right scroll spring (7) starts to rotate reversely after the elastic potential energy reaches a threshold value, a sensor (5) on the deep groove ball bearing A (6) collects the information of the rotating speed of the flywheel disc to an ECU (17) like a rotating speed sensor, the ECU (17) sends an instruction to the deep groove ball bearing A (6) to lock the flywheel disc in combination with the rotating speed information of the flywheel disc A (4), meanwhile, the telescopic rod A (3) is retracted, and the flywheel disc A (4) rotates back to an end point along the fixed shaft (13); a sensor (5) on the deep groove ball bearing B (9) collects the information of the rotating speed of the flywheel disc to a fixed ring (16) like a rotating speed sensor, the fixed ring (16) combines the rotating speed information of the flywheel disc B (10) to give an instruction to the deep groove ball bearing B (9) to lock the deep groove ball bearing B, meanwhile, a telescopic rod B (14) is retracted, and the flywheel disc B (10) rotates back to an end point along a fixed shaft (13).
