[0001] The present application belongs to the technical field of vehicle shock absorption, and in particular relates to a structure for eliminating vibration of a motor vehicle. Background Art

[0002] At present, the vibration reduction methods of motor vehicles include independent suspension or non-independent suspension, and the main structure is the parallel connection of springs and shock absorbers, and there are also springs replaced by air springs. However, neither springs nor shock absorbers can fundamentally solve the chassis vibration phenomenon when the vehicle encounters obstacles. What they can do is to make the amplitude of vibration different from the level of the vehicle.

[0003] Some vehicles reduce vibration to a certain extent by adjusting the damping size of the shock absorber, but the goal of vibration reduction is not achieved fundamentally. Summary of the invention

[0004] The purpose of the present application is to provide a structure for eliminating vibration of a motor vehicle to solve or alleviate at least one problem in the background technology.

[0006] Further, the energy generation unit includes: a first caliper, a second caliper, a disc, a first hydraulic system, and a second hydraulic system;

[0007] The disc is mounted on another wheel axle matching the wheel in trouble, and is coaxially mounted;

[0008] The first caliper and the second caliper are configured to match the position of the disc and can rotate around the wheel axis of the other wheel by a predetermined angle;

[0009] The first hydraulic system and the second hydraulic system are connected to the first caliper and the second caliper. Under the control of the first hydraulic system and the second hydraulic system, the first caliper and the second caliper can clamp the disc to generate friction, thereby rotating the first caliper and / or the second caliper by a predetermined angle.

[0010] Furthermore, the first caliper and the second caliper are respectively arranged at relative positions horizontally with respect to the wheel axle diameter of the other wheel.

[0011] Furthermore, the first hydraulic system and the second hydraulic system both include an electromagnet and a main pump, the oil pipe of the main pump is connected to the iron core of the electromagnet, and the output pressure of the main pump can be controlled by moving the iron core of the electromagnet, thereby controlling the friction force between the first caliper and the second caliper and the disc.

[0012] Furthermore, the energy consumption unit includes: a first pull wire, a second pull wire, a main spring, a secondary spring, a positive bracket, and an inverted bracket;

[0013] The main spring is the main vibration reduction mechanism for the wheel that encounters an obstacle;

[0014] The auxiliary spring is sleeved on the main spring;

[0015] The positive bracket is arranged on the bottom side of the main spring;

[0016] The inverted bracket is arranged between the main spring and the auxiliary spring;

[0017] One end of the first cable is connected to the positive bracket, and the other end is connected to the first caliper;

[0018] One end of the second cable is connected to the inverted bracket, and the other end is connected to the second caliper;

[0019] When the first caliper and / or the second caliper rotate coaxially around the other wheel axle, the force of the first hydraulic system or the second hydraulic system is controlled to drive the first pull wire or the second pull wire to move, thereby driving the main spring to extend or shorten to the same length as the obstacle, thereby achieving the goal of keeping the distance between the vehicle chassis and the ground unchanged.

[0020] Furthermore, the positive bracket and the reverse bracket are connected via a conduit, thereby converting the moving direction of the second pull wire into the extension direction of the main spring.

[0021] Furthermore, the energy consumption unit also includes: a displacement sensor, which is used to measure the length change amplitude of the extension and shortening of the main spring, so as to control the displacement size of the main spring to remain within a predetermined range when the obstacle wheel encounters an obstacle.

[0022] Furthermore, the structure also includes: a laser sensor and a controller, wherein the laser sensor is arranged at the front end of the wheel encountering an obstacle and faces the ground, and is used to measure the obstacle size information at the front end of the wheel encountering the obstacle, and the controller is used to control the hydraulic force of the first hydraulic system and / or the second hydraulic system according to the obstacle size information of the laser sensor, thereby controlling the extension or contraction amplitude of the main spring.

[0024] Furthermore, the relationship between the obstacle-encountered wheel and the other wheel is:

[0025] When the left front wheel is the wheel that encounters an obstacle, the left rear wheel is the other wheel;

[0026] When the right front wheel is the wheel that encounters an obstacle, the right rear wheel is the other wheel;

[0027] When the left rear wheel is the wheel that encounters an obstacle, the left front wheel is the other wheel;

[0048] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0049] The source of vibration during the operation of a motor vehicle is that the height of the convex obstacle encountered by the vehicle is not equal to the length of the shortened spring. In the present application, the kinetic energy of the vehicle is converted into the energy of the spring extension or shortening during the operation of the vehicle, so that the spring is extended or shortened according to the appropriate length to ensure that the vehicle vibrates within a smaller range, thereby eliminating the vibration of the motor vehicle.

[0050] The structure for eliminating motor vehicle vibration provided in the present application mainly includes an energy generating unit and an energy consuming unit.

[0051] The energy generating unit includes a first caliper, a second caliper, a disc, a first hydraulic system, and a second hydraulic system. The disc is mounted on a wheel axle that matches the wheel that encounters the obstacle, and is coaxially mounted. The first caliper and the second caliper are configured to match the position of the disc and can rotate around the wheel axle of the wheel at a certain angle. The first caliper and the second caliper are connected to the first hydraulic system and the second hydraulic system. Under the control of the first hydraulic system and the second hydraulic system, the first caliper and the second caliper can clamp the disc to generate friction, thereby rotating the first caliper and the second caliper at a certain angle.

[0052] In the present application, the first caliper and the second caliper matched with the disc are respectively arranged at relative positions where the wheel axle diameter is close to horizontal. The first caliper and the second caliper can drive the first cable and / or the second cable to move, thereby controlling the extension and shortening of the main spring of the obstacle wheel.

[0053] The energy consumption unit includes a first cable, a second cable, a main spring, a secondary spring, a positive bracket and an inverted bracket. The main spring is the main damping mechanism of the obstacle wheel, the secondary spring is sleeved on the main spring, and the positive bracket is arranged on the bottom side of the main spring, the inverted bracket is arranged between the main and secondary springs, the first cable is connected to the positive bracket, and the second cable is connected to the inverted bracket. When the first caliper or the second caliper of one of the above wheels rotates coaxially around its wheel axle, by controlling the force of the first hydraulic system or the second hydraulic system, the first cable or the second cable is driven to move and then drive the main spring to extend or shorten to the same length as the obstacle, so as to achieve the goal of keeping the distance between the chassis of the vehicle and the ground unchanged.

[0054] To make the above process clearer, the following is an explanation using the example of controlling the left front wheel for vibration reduction.

[0055] like Figures 1 to 3 As shown, the energy generating unit for controlling the vibration reduction of the left front wheel 3 includes a first caliper 23, a second caliper (blocked and not shown), a disc 24, a first hydraulic system 21a, and a second hydraulic system 21b. The wheel that cooperates with the left front wheel 3 for vibration reduction is the left rear wheel 1. The disc 24 is coaxially installed with the left rear wheel 1, and a first caliper 23 and a second caliper are installed on the front and rear sides of the disc 12. The first hydraulic system 21a is connected to the first caliper 23 through a first hydraulic pipe 22a, and the second hydraulic system 21b is connected to the second caliper through a second hydraulic pipe 22b. The first caliper 23 and the second caliper are controlled by the first hydraulic system 21a and the second hydraulic system 21b to rub against the disc and rotate around the wheel axle of the rear wheel 1 by a certain angle, thereby driving the first cable 25a and the second cable 25b to be stretched, which are used to drive the main spring of the left front wheel to shorten and the main spring of the left front wheel to extend respectively.

[0056] In the present application, the first hydraulic system 21a includes an electromagnet 211 and a main pump 212. The oil pipe of the main pump 212 is connected to the iron core of the electromagnet 211. The movement of the iron core of the electromagnet 211 can control the output pressure of the main pump 212, thereby controlling the friction force between the first caliper 23 and the disc 24. The second hydraulic system 21b is the same as the first hydraulic system 21a, and will not be described in detail here.

[0057] The main spring 5 is the main vibration reduction structure of the left front wheel 3, and its expansion and contraction directly affects the vibration reduction effect of the vehicle chassis.

[0058] A laser sensor 5 for measuring the size of obstacles is installed at a certain distance from the front end of the main spring 41, and its output signal is provided to the controller. The laser sensor 5 irradiates the bottom surface to detect the size information of obstacles on the ground. The laser sensor 5 is connected to the vehicle body structure or the wheel axle position at the lower end of the main spring 41 through the sensor bracket 51. By installing the fixed bracket 51 of the laser sensor 5 in a relatively static position relative to the wheel axle, the laser sensor output is guaranteed to be constant when the vehicle is running on a flat road.

[0059] It should be noted that, considering the excitation time of the electromagnet, the size information of the obstacle must be collected before the left wheel hits the obstacle for calculation by the signal processing module. In this embodiment of the present application, the laser sensor 5 is installed about 600 mm in front of the axis of the left front wheel 3.

[0060] The main spring 41 and the auxiliary spring 42 are connected in series, the positive bracket 44 is installed at the bottom of the main spring 41, and an inverted U-shaped inverted bracket 43 is installed between the main spring 41 and the auxiliary spring 42. The positive bracket 44 and one side of the inverted bracket 43 are connected by a guide rod. The first pull wire 25a passes through the other side of the inverted bracket 43 and is connected to the positive bracket 44, and the second pull wire 25b is connected to the inverted bracket 43. The first pull wire 25a can pull the positive bracket 44 to move upward, thereby controlling the main spring 41 to contract; the second pull wire 25b can pull the inverted bracket 43 to move upward, thereby controlling the main spring 41 to extend, thereby completing the extension and shortening of the main spring 44.

[0061] In the preferred embodiment of the present application, a displacement sensor 45 is connected in parallel at a certain distance from the auxiliary spring 43, and the displacement sensor 45 measures and controls the length change amplitude of the extension and shortening of the main spring 41, so that when the left front wheel 3 encounters an obstacle, the displacement size of the main spring 43 is controlled to remain unchanged or change within a certain small range to reach the optimal value. Through the automatic learning function, the longer the vehicle runs, the better the vehicle vibration reduction effect will be.

[0062] In addition, the structure for eliminating motor vehicle vibration provided by the present application also includes a controller and a power module. The controller is used to receive information detected by the laser sensor 5, and control the hydraulic force of the first hydraulic system 21a and the second hydraulic system 21b according to the information, thereby controlling the displacement of the first pull wire 25a and the second pull wire 25b, and finally controlling the expansion and contraction amount of the main spring 41. The power module is used to provide power to components that require electrical energy, including laser sensors, displacement sensors, solenoid valves of the hydraulic system, etc.

[0063] The present application provides a structure for eliminating vibration of a motor vehicle. When the left front wheel 3 encounters a convex obstacle or a concave obstacle while the wheel is running, the laser sensor 5 detects the obstacle size information in advance because it is a certain distance in front of the left front wheel 3. The controller calculates and outputs a changing duty cycle signal according to the vehicle speed, and drives the strength of the electromagnet of the hydraulic system. The moving iron core in the electromagnet acts on the lever of the main pump, and the main pump acts on the caliper through the oil pipe. The caliper then presses the disc to generate friction. The caliper and the disc rotate together at a certain angle under the action of friction, and then drives the cable to move, and finally acts on the main spring, causing the main spring to produce appropriate extension or contraction, thereby ensuring that the vehicle vibrates within a smaller range, thereby eliminating the vibration of the motor vehicle and increasing comfort.

[0064] It should be noted that the above embodiment of the present application provides that the energy for the expansion and contraction of the left front wheel spring of the motor vehicle comes from the left rear wheel, and the expansion and contraction of the springs of other wheels is not provided. The contraction of the springs of other wheels can be set as follows: the expansion and contraction energy of the right front wheel spring comes from the right rear wheel, the expansion and contraction energy of the left rear wheel spring comes from the left front wheel, and the expansion and contraction energy of the right rear wheel spring comes from the right front wheel.

[0065] The structure for eliminating motor vehicle vibration provided by the present application drives one wheel by another wheel, thereby preventing the expansion and contraction energy of the main spring of a certain wheel from being driven by itself, causing the wheel to slip when encountering an obstacle, thereby hindering the acquisition of energy when the caliper rotates.

[0066] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
