Embodiment 1

[0037] A magneto-rheological elastomeric suspension element for in-wheel motors, such as Figure 1~4 ( figure 1 and image 3Arc electromagnet is not shown), including magnetorheological elastomer 1 and at least one set of magnetic generation components arranged on the magnetorheological elastomer, the magnetorheological elastomer is cylindrical, each group of magnetic generation components Both include two electromagnet mechanisms arranged symmetrically along the circumference of the magnetorheological elastomer and two piezoresistive sensors 2 respectively connected to the electromagnet mechanisms. The electromagnet mechanisms are powered by an external power supply to generate an initial magnetic field, and the magnetic The sense line passes through the magnetorheological elastomer 1 corresponding to the electromagnet mechanism, so that the damping of the magnetorheological elastomer 1 corresponding to the electromagnet mechanism is greater than the intrinsic damping of the...

Abstract

The invention relates to a magnetorheological elastomer suspension element for a hub motor. The element comprises a magnetorheological elastomer, and at least one set of magnetic generation modules arranged on the magnetorheological elastomer; the magnetorheological elastomer is cylindrical; each set of magnetic separation modules comprises two electromagnet mechanisms symmetrically arranged in the peripheral direction of the magnetorheological elastomer, and two piezoresistance sensors respectively connected with the electromagnet mechanisms; the electromagnet mechanisms are powered through an external power supply to generate an initial magnetic field; magnetic induction lines of the initial magnetic field penetrate through the magnetorheological elastomer corresponding to the electromagnet mechanisms; and the piezoresistance sensors are matched with the electromagnet mechanisms, are positioned on the inner side wall of the magnetorheological elastomer, and are used for changing current input in the electromagnet mechanisms according to induced pressure values to change the magnetic field intensity so as to change damping of the magnetorheological elastomer corresponding to the electromagnet mechanisms. Compared with the prior art, the element has such advantages as compact structure and adjustable damping dynamic state.

Description

technical field [0001] The invention belongs to the field of suspension elements, and relates to a magneto-rheological elastomer suspension element, in particular to a magneto-rheological elastomer suspension element for a hub motor. Background technique [0002] Magneto-rheological elastomer functional composite materials are prepared by dispersing micron or nano-sized soft magnetic particles in different types of carriers. Because their rheological properties can change continuously, rapidly and reversibly with the applied magnetic field, the magneto-sensitivity intelligent Soft materials have been widely used in fields such as construction, vibration control, and automotive industry, and have attracted increasing attention. [0003] The new electric wheel is mainly composed of motor, suspension system, brake, hub, rim, tire and so on. It differs from the existing electric wheel structure in that: a suspension element is provided between the hub motor stator (housing) and...
