Abstract

The utility model discloses a technical proposal of an electromagnetic adjustable shock absorber. An electromagnetic shock absorber generally comprises an upper cylinder and a lower cylinder, the lower cylinder is pressed into the upper cylinder when the electromagnetic shock absorber bears a load, two permanent magnets respectively arranged in the upper cylinder and the lower cylinder overcome the bounce of wheels generated when a vehicle runs on a road under the effect that like poles repel each other, therefore the suspension balance of the wheels are maintained, and the vibration of the vehicle is reduced. The utility model adopts the technical proposal that a coil, a wire and a switching device are increased in the electromagnetic shock absorber, when the wire is connected through the switch, the coil is powered on, magnetic field movement is generated, and the magnetic force of the permanent magnets are increased; similarly, when the wire is disconnected through the switch, the coil is powered off, and the permanent magnets are only provided with the self magnetic force. In the condition of bad road and light load, when the bounce is increased obviously, the switch is powered on to adjust the magnetic force and better protect the security of the vehicle and the load and the running quality.

Description

The electromagnetism adjustable damper

Technical field

The utility model relates to a kind of vehicle shock absorber, specifically is a kind of electromagnetism adjustable damper.

Background technique

At present, vibration damper has hydraulic type, spring, electromagnetic type several types, and the Sealing of hydraulic type is aging easily, easily causes leakage of oil and environmental pollution problem; Spring is to utilize the restorable ability of object, and this mode is easy to generate fatigue, fracture in frequent deformation repeatedly; Electromagnetic type is used the resulting magnetic suspension of two same pole generation repulsive forces and is reached good vibration isolation.But because the gap of vehicle-mounted load and road quality is big, same electromagnetism damping can not be protected the safety of vehicle and vehicle-mounted thing and the quality of travelling better.

Summary of the invention

The purpose of this utility model is: provide a kind of when vehicle-mounted load and road quality are different, can adjust the electromagnetism adjustable damper of magnetic force size, protect the safety of vehicle and vehicle-mounted thing and the quality of travelling better.

The technical solution of the utility model is; Movable axis links one group of upper and lower sleeve, install bearing means in the top cylinder, upper bearing equipment links goes up permanent magnet, coil is installed on the upper bearing equipment, the link tester of coil is installed lower bearing equipment toward the vibration damper outside in the connecting thread way switch, doffing, link permanent magnet down, upper and lower two block permanent magnets are that the N utmost point same sex is relative.

During the movable axis bearing load, doffing is pressed into top cylinder, is installed in the permanent magnet in the upper and lower tube respectively, under the effect that the same sex is repelled each other, overcomes wheel in the spring that travels down produced, and makes it keep the suspension balance, reduces the vibrations of vehicle.Under the situation poor at road, that load is light; when strengthening, spring uses the utility model; the enable switch energising; coil produces Movement in Magnetic Field; increase the permanent magnet same sex dynamics of repelling each other; make vehicle reduce vibrations, reach the purpose that to adjust the magnetic force size, protect the safety of vehicle and vehicle-mounted thing and the quality of travelling better.

Description of drawings

Accompanying drawing is a schematic representation of the present utility model, among the figure: 1, coil, 2, upper bearing equipment, 3, line switching, 4, go up permanent magnet, 5, top cylinder, 6, permanent magnet down, 7, lower bearing equipment, 8, movable axis, 9, doffing.

Specific embodiments

The concrete practical plan of the utility model is: coil (1) is placed in upper bearing equipment (2), presses close to go up permanent magnet (4), and the circuit of coil turns on the vibration damper outside, and line switching (3) is installed in appropriate location in the operator cabin, easy-to-operat.

When vehicle movable axis (8) load-bearing, doffing (9) is pressed into top cylinder (5), last permanent magnet (4) direction that following permanent magnet (6) upward axis bearing apparatus (2) on the lower bearing equipment (7) is installed advances, and upper and lower two block permanent magnets are that the N utmost point same sex is relative, one is approaching slightly, just produce mutually exclusive strength, make vehicle reduce vibrations.

Claims

1. electromagnetism adjustable damper, it is characterized in that: movable axis links one group of upper and lower sleeve, install bearing means in the top cylinder, upper bearing equipment links goes up permanent magnet, and coil is installed on the upper bearing equipment, and the link tester of coil is toward the vibration damper outside, the connecting thread way switch, lower bearing equipment is installed in the doffing, is linked permanent magnet down, upper and lower two block permanent magnets are that the N utmost point same sex is relative.
