Description

A type of suspension car shock absorber Technical Field

[0001] This utility model relates to the field of suspension vehicle shock absorbers, and more specifically, to a suspension vehicle shock absorber. Background Technology

[0002] The suspension system is the collective term for all force-transmitting connections between a car's frame and axles or wheels. Its function is to transmit forces and torques acting between the wheels and the frame, buffer the impact forces transmitted from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure a smooth ride. The suspension system's primary function is to support the vehicle body and improve ride comfort; different suspension setups will result in different driving experiences. Despite its seemingly simple appearance, the suspension system integrates multiple forces and determines a car's stability, comfort, and safety, making it one of the most crucial components of modern automobiles. Currently, there are various types of suspension damping, with air suspension and spring damping being the most common.

[0003] In the prior art, such as the prior art patent, according to the authorization announcement number CN 119755255 A, this invention discloses a suspended automobile shock absorber and control method; the shock absorber, from the inside out, consists of a length measuring sensor tension spring, a permanent magnet tube, a damping coil sleeved on the permanent magnet tube, a damping coil, a secondary spring, a main spring, and a rubber outer sleeve. The upper end of the length measuring sensor, the upper end of the secondary spring, and the main spring are fixed under the top plate. The permanent magnet tube is installed below the length measuring sensor, and the lower end of the main spring is fixed on the base. The lower end of the screw rod is installed on the top of the inverted steel basin cover. The driven gear installed on the lower section of the screw rod meshes with the output gear and the calculator gear of the gear reduction motor. The lower end of the secondary spring is fixed on the lifting platform, and the nut at the center of the lifting platform is screwed on the screw rod. Four sliding tubes pass through four holes on the lifting platform, with the lower end fixed to the top of the inverted steel basin cover and the upper end fixed to the damping platform. The upper end of the screw rod is installed on the damping platform, and the damping coil is installed on the damping platform. The weighted elastic coefficient is adjusted by adjusting the position of the lifting platform.

[0004] In the aforementioned patent, the nut manual adjustment structure is set, which is inconvenient to adjust during use. Moreover, during the lifting and lowering adjustment, the compression and shock absorption pressure is supported on the motor. The motor cannot withstand the floating pressure when squeezed up and down, which can easily lead to motor damage. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a suspended automotive shock absorber. During use, a threaded rod is used to control the up-and-down movement of a permanent magnet. The motor is located outside the outer shock absorber cylinder, making it easy to adjust up and down. The pressure does not directly act on the outside of the motor, thus preventing damage to the motor. It also automatically adjusts the lifting height, allows for adjustment of the spacing between electromagnets, and allows for adjustment of the electromagnetic force and lifting stiffness.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A suspension-type automotive shock absorber includes a shock absorber cylinder. A telescopic sliding rod is inserted through the inner surface of the shock absorber cylinder. An electromagnet is fixedly connected to the surface of the telescopic sliding rod. A groove is provided on the inner surface of the shock absorber cylinder, and a permanent magnet is slidably connected to the inner surface of the groove. A threaded rod is connected to the upper inner surface of the shock absorber cylinder via a bearing. A bevel gear disk is fixedly connected to the outer surface of the threaded rod. A motor is fixedly connected to the outer surface of the shock absorber cylinder. A bevel gear is fixedly connected to the outer end surface of the motor's drive shaft. The device is configured for use... The threaded rod controls the up-and-down movement of the permanent magnet. The motor is located outside the outer shock-absorbing cylinder, making it easy to adjust up and down. Pressure is not directly applied to the outside of the motor, reducing the risk of damage. The system automatically adjusts the lifting height, allowing for adjustment of the spacing between the electromagnets, the electromagnetic force, and the stiffness of the lifting motion.

[0008] Furthermore, the bevel gear meshes on the outer surface of the bevel gear disk, and the bevel gear disk and the bevel gear mesh with each other, which facilitates the formation of bevel gear meshing transmission. When the bevel gear rotates, it can drive the bevel gear disk to rotate, which can drive the threaded rod to rotate, making it easy to control the drive.

[0009] Furthermore, a spring is fitted onto the outer surface of the telescopic sliding rod.

[0010] Furthermore, a first mounting bushing is provided on the upper surface of the shock-absorbing cylinder, and a second mounting bushing is fixedly connected to the lower surface of the telescopic sliding rod.

[0011] Furthermore, a support disc is fixedly connected to the upper surface of the second mounting bushing.

[0012] Furthermore, the upper inner surface of the shock-absorbing cylinder is provided with a recessed groove, in which a bearing is embedded and fixed, and the upper outer surface of the threaded rod is fixedly connected to the inner surface of the inner ring of the bearing.

[0013] Furthermore, the outer surface of the permanent magnet is provided with a positioning protrusion, and the outer surface of the positioning protrusion is slidably connected to the inner surface of the groove.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) By setting a threaded rod to control the permanent magnet to move up and down during use, the motor is set outside the external shock-absorbing cylinder, which makes it easy to adjust up and down, and the pressure will not directly act on the outside of the motor, so it is not easy to damage the motor. It can automatically adjust the lifting and lowering, adjust the distance between the electromagnets, adjust the electromagnetic force, and adjust the lifting softness and hardness.

The automatic adjustment of lifting and lowering, the adjustable spacing between the electromagnets, the adjustable electromagnetic force, and the adjustable lifting stiffness are all features of the shock absorber.

[0027] The bevel gear 10 meshes on the outer surface of the bevel gear disk 8, and the bevel gear disk 8 and the bevel gear 10 mesh with each other; this facilitates meshing transmission, and can form a bevel gear meshing transmission.

[0032] In use, a telescopic sliding rod 2 is inserted through the inner surface of the shock-absorbing cylinder 1.

Clockwise rotation is the motor rotating in the forward direction, and counterclockwise rotation is the motor rotating in the reverse direction. According to the forward and reverse control circuit diagram and its principle analysis, to achieve the forward and reverse rotation of the motor, any two phases of the three-phase power supply lines connected to the motor can be interchanged to achieve the reverse rotation purpose, which is the existing technology). It can drive the permanent magnet 5 to move up and down, and the distance between it and the electromagnet 3 at the bottom can be adjusted. When the distance is close, the stroke is short and the suspension is stiff. When the stroke is long, the suspension is high and the suspension is soft.
