Description

Technical Field

[0001] The utility model relates to the technical field of suspensions, in particular to a motor suspension. Background Art

[0002] The linear motor is composed of structures such as permanent magnets and coils. The working principle is to form an electric current by cutting the magnetic lines of force generated by the permanent magnets through the coils. The current can be passed into the coils to form a magnetic field that attracts or repels the permanent magnets, thereby forming a damping force similar to a suspension spring. It can be applied to vehicles to actively adjust the different body postures and wheel heights of the vehicle, so that the vehicle has higher passability and stability when driving on complex road conditions. The linear motor suspension in the related art generally includes a stator part and a mover part. Under the action of external force, the mover part can move linearly relative to the stator part, thereby adjusting the relative position between the axle (also called the axle) and the frame (also called the body).

[0003] Publication (announcement) No.: CN117429217A discloses a motor suspension and a vehicle, comprising: a first permanent magnet mechanism, a second permanent magnet mechanism, a shell mechanism, a coil mechanism and a rolling mechanism; the first permanent magnet mechanism and the second permanent magnet mechanism are fixedly installed inside the shell mechanism, the second permanent magnet mechanism is arranged around the first permanent magnet mechanism and is spaced apart from the first permanent magnet mechanism, the space between the first permanent magnet mechanism and the second permanent magnet mechanism forms an insertion space for the coil mechanism to be inserted, the coil mechanism can move relative to the shell mechanism along the extension direction of the insertion space, and cut the magnetic field generated by the first permanent magnet mechanism and the second permanent magnet mechanism; the rolling mechanism can be rotatably connected to the shell mechanism, and is used to roll and abut with the coil mechanism when the shell mechanism and the coil mechanism move relative to each other.

[0004] Although the above scheme reduces the friction generated by the motor suspension during operation and reduces the consumption of frictional work, the motor is generally installed by bolts. If the bolts are used in a corrosive environment, their bearing capacity may be reduced due to corrosion, especially when used outdoors or in a humid environment, special attention should be paid.
