A linear motor type shock absorber in driving wheel

Abstract

The invention relates to a linear motor type shock absorber in a driving wheel, which belongs to the technical field of auto parts. The linear motor shock absorber mainly includes motor shock absorbers, wheels, passive suspension springs and passive dampers. The motor shock absorbers are installed in the wheels through brackets. The motor shock absorbers include peripheral magnetic isolation sleeves, end covers, dynamic stator, stator, self-lubricating positioning bearing and bracket; the mover includes an annular mover core, winding coils, Hall sensors, and the inner ring of the mover core has annular grooves and mover teeth; the stator includes a ring diameter Inner magnetized permanent magnet, ring-shaped right-side magnetized permanent magnet, ring-shaped outer-diameter charged permanent magnet, ring-shaped left-side magnetized permanent magnet, ring-shaped stator magnetically conductive back iron and cylindrical support shaft; motor shock absorber and mounted on the wheel The outer passive suspension springs and passive dampers are connected in parallel. The invention provides a linear motor type shock absorber in the driving wheel, which has the characteristics of adjustable operating power, passive energy recovery, small volume, large stroke and the like.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a linear motor type shock absorber in a driving wheel. Background technique [0002] The linear motor is a structural deformation of the rotary motor, which can be seen as a rotary motor that is cut along its radial direction and then flattened to evolve. With the rapid development of automatic control technology and microcomputers, higher requirements are put forward for the positioning accuracy of various automatic control systems. Devices are far from meeting the requirements of modern control systems. For this reason, many countries in the world are researching, developing and applying linear motors, making the application fields of linear motors more and more extensive. [0003] At present, the widely used oil-gas active shock absorbers have problems such as complex structure, low efficiency, low power density and large pollution. The linear motor shock absorber converts e...

AI Technical Summary

Problems solved by technology

[0003] At present, the widely used oil-gas active shock absorbers have problems such as complex structure, low efficiency, low power density and large pollution. The linear motor shock absorber converts electrical energy into mechanical energy, which simplifies the mechanical structure and improves the efficiency. Moreover, the operating force can be adjusted at will, and energy recovery can be carried out.

[0004] At present, the linear motor shock absorber is rarely used in the car due to the limitation of the suspension installation space.
