Description

Technical Field

[0001] The invention relates to the field of suspension systems, in particular to a vehicle stabilizer and a suspension assembly having the vehicle stabilizer. Background Art

[0002] With the rapid development of technology, the market has increasingly higher requirements for the stability and comfort of passenger car chassis.

[0003] In the process of automobile design, in order to improve comfort, the natural frequency of the suspension is usually reduced and the suspension stiffness is designed to be relatively low, which results in affecting the stability of the vehicle chassis.

[0004] Therefore, a lateral stabilizer bar is designed in the suspension system to increase the suspension roll angle stiffness, reduce the body roll angle, and improve chassis stability.

[0005] During the design of the suspension system, the lateral stabilizer bar is connected to the chassis parts through the stabilizer bar tie rod. When the left and right wheels have a relative vertical displacement, the stabilizer bar twists and generates a torsional force, which will be transmitted to the suspension through the stabilizer bar tie rod, thereby increasing the chassis roll angle stiffness and reducing the body roll angle.

[0006] However, tension will be generated between the suspensions on both sides, which will increase the suspension stiffness, increase the vehicle's natural frequency, and reduce the comfort of the vehicle's chassis; when the vehicle is driving on a bumpy road, the wheels on the left and right sides will have small and frequent vertical relative displacements, and the anti-roll bar will also twist frequently, causing the vehicle to sway from side to side, affecting the stability of the vehicle's chassis.

[0007] In addition, in order to improve the roll stiffness of the car, a stabilizer bar (metal rod) is generally used, which is connected to the steering knuckle or sliding column through a connecting rod to passively suppress the roll of the car, thereby improving the roll stiffness of the car and achieving safety and comfort of car driving.

[0008] The overall structure of the traditional stabilizer bar and connecting rod is relatively complex and can only be adjusted passively, without the ability to actively adjust the suspension roll stiffness.

[0009] The existing patent 201520465241.3 - Motor vehicle stabilizer bar structure also does not clearly disclose the technical content for solving the above technical problems.

[0040] Furthermore, in the present invention, the magnetic field assembly includes a current converter 6 arranged on the outer shell 2 and a magnetic field generator 7 arranged in the outer shell 2; the magnetic field generator 7 is arranged relative to the piston-type magnetic suspension 5; the current converter 6 disclosed in the present invention can adapt the current direction as needed, and the magnetic field generator 7 can generate a corresponding magnetic field, which is convenient for use with the piston-type magnetic suspension 5.

[0041] At the same time, in the present invention, a magnetic field generator 7 is respectively provided at both ends of the shell 2; in the present invention, a magnetic field generator 7 is respectively provided at both ends of the shell 2, and the magnetic fields generated by the magnetic field generators 7 at both ends of the shell 2 are in opposite directions, and the piston-type magnetic suspension 5 is arranged between the two magnetic field generators 7. Based on such a setting, the two magnetic field generators 7 can act on the piston-type magnetic suspension 5 at the same time, thereby better controlling the extension and contraction of the stabilizer, and facilitating the subsequent use, and realizing the extension or contraction of the piston rod 3 in the shell 2 as needed; thereby realizing the adjustment of the suspension roll stiffness during subsequent use.

[0051] specific:

[0052] The present invention discloses a vehicle stabilizer, comprising a stabilizer body 1, wherein the stabilizer body 1 comprises a shell 2; the shell 2 is hollow inside to form a storage cavity; a piston rod 3 is plugged into the shell 2; a magnetic suspension structure is provided on the shell 2; the magnetic suspension structure comprises a piston-type magnetic suspension 5 arranged on one end of the piston rod 3 inside the shell 2 and a magnetic field component arranged in the shell 2; the magnetic field component is used in conjunction with the piston-type magnetic suspension 5; the magnetic field component can generate suction or repulsion with the piston-type magnetic suspension 5; the magnetic field component comprises a current frequency converter 6 arranged on the shell 2 and a magnetic field generator 7 arranged in the shell 2; the magnetic field generator 7 is arranged opposite to the piston-type magnetic suspension 5; a magnetic field generator 7 is respectively provided at both ends of the shell 2, and the piston rod 3 passes through a magnetic field generator 7.

[0053] In a suspension assembly using the vehicle stabilizer, generally two vehicle stabilizers are symmetrically arranged in the suspension assembly.

[0054] The invention discloses a vehicle stabilizer and a suspension assembly.

[0055] It can improve the safety and comfort of car driving, reduce the weight of the car and reduce energy consumption.

[0056] The vehicle stabilizer disclosed in the present invention is mainly a magnetic suspension stabilizer, and the main technical problem solved is: combining a traditional stabilizer bar and a connecting rod into one, which not only reduces the weight of the whole vehicle, but also reduces the energy consumption of the vehicle.

[0057] The working principle of this structure is as follows: when a car is driving on an uneven road, according to the different rolls, the vehicle stabilizer disclosed in the present invention outputs different currents to generate magnetic field forces, increase lateral forces, and suppress rolls. At the same time, it also suppresses wheel bouncing, increases wheel grip, and increases the safety of car driving.

[0058] Specifically, the installation method of the vehicle stabilizer disclosed in the present invention requires that one end is connected to the steering knuckle or the sliding column, and the other end is connected to the vehicle body or the frame.

[0059] Working principle:

[0060] When the piston magnetic suspension in the vehicle stabilizer on the left side of the vehicle moves upward, under the control of the control system, the current passing through the magnetic field generator 7 near one end of the shock absorber will be increased to increase the magnetic field.

[0061] In addition, the piston magnetic suspension will also increase the same magnetic field, causing mutual repulsion with the magnetic field generator 7 near one end of the shock absorber, thereby inhibiting the movement of its suspension and body.

[0062] The vehicle suspension system will input current to the stabilizer on the right side of the car in the opposite direction to that on the left side, generating a reverse force. The left and right sides will act on each other, thus enhancing the lateral stiffness of the car and improving its driving safety.

[0063] The vehicle stabilizer disclosed in the present invention replaces the traditional stabilizer bar and connecting rod, and increases the roll stiffness of the whole vehicle.

[0064] After the present invention is implemented, the weight of the whole vehicle can be reduced, thereby reducing energy consumption;

[0065] After the implementation of the present invention, the roll stiffness of different vehicles can be actively provided more effectively, thereby more effectively improving the safety of vehicle operation.

[0066] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
