Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shock pads, and in particular to a shock pad and a vehicle. BACKGROUND

[0002] The shock pad is one of the key parts of the electric power steering gear of the vehicle, which can not only relieve the noise and wear caused by the meshing and rubbing between the shaft couplings, but also provide axial pre-tightening force for the bearings of the worm and the motor to reduce the bearing running noise and improve the driving comfort.

[0003] In the related art, when the axial pre-tightening force is provided by the shock pad, one method is to provide the axial pre-tightening force by adding a spring mechanism between the shock pad and the shaft coupling, but this method requires the additional design of a matching spring mechanism, resulting in high cost. Another method is to design a shock pad with axial pre-tightening force function, which usually has a protruding point structure in the axial direction of the shock pad, and the axial pre-tightening force is provided by the contact between the protruding point and the shaft coupling. However, the axial structure of the shock pad designed by this method is relatively complex, and the protruding point structure has small rigidity, which is easily crushed or worn under the action of large compression force, thereby reducing the service life of the shock pad. SUMMARY

To this end, the first object of the present application is to provide a shock pad, which is provided with a plurality of shock-absorbing parts arranged in the circumferential direction of the outer side wall of the body in sequence and at intervals. In the axial direction of the shock pad, the first end and / or the second end of the shock-absorbing part protrudes from the body, so that the shock-absorbing part can provide axial pre-tightening force without the need to provide axial pre-tightening force by adding a spring mechanism, thereby reducing production cost. At the same time, there is no need to additionally provide a protruding point structure at the first end and / or the second end of the shock-absorbing part, thereby simplifying the axial structure design of the shock pad. In addition, compared with the protruding point structure, the shock-absorbing part with a single rigidity structure design has larger rigidity and can withstand larger compression force, thereby being less likely to be crushed or worn, thereby improving the service life of the shock pad.

[0013] In some examples of the present application, the end face of at least one end of the connecting section is configured as an arc-shaped plane, and the arc-shaped plane is concave towards the inside of the damping part in the axial direction of the damping pad.

[0014] In some examples of the present application, the cross-sectional area of the compression section is the same in the radial direction of the damping pad.

[0033] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and characters throughout the figures denote the same or like elements or components, which detailed description is only exemplary and not intended to limit the present application.

[0034] The shock pad 100 according to embodiments of the present application is described below with reference to the attached drawings, which can be installed on a vehicle, but the present application is not limited thereto, and the shock pad 100 can also be applied to other devices that need to be provided with the shock pad 100. The present application is described by way of example with the shock pad 100 applied to a vehicle.

[0035] As shown in Figure 1 The shock pad 100 according to the first aspect of the present application comprises a body 10 and a plurality of shock-absorbing portions 20. The body 10 is annular, and the plurality of shock-absorbing portions 20 are arranged on the outer side wall of the body 10 and are spaced apart along the circumferential direction of the body 10. Each shock-absorbing portion 20 has opposite first and second ends, and the first and / or second end protrudes from the body 10. That is, only the first end of the shock-absorbing portion 20 can be arranged to protrude from the body 10, or only the second end of the shock-absorbing portion 20 can be arranged to protrude from the body 10, or both the first and second ends of the shock-absorbing portion 20 can be arranged to protrude from the body 10. The specific arrangement method is selected according to the needs. Further, in order for those skilled in the art to clearly understand the present application, the first and second ends of the shock-absorbing portion 20 are arranged to protrude from the body 10 at the same time as an example in the present application.

[0036] It should be noted that the shock pad 100 is an integrally formed structure, which is generally made of polyurethane material. It not only has the general properties of rubber, but also is more wear-resistant than ordinary rubber.

[0037] Specifically, as shown in Figure 1 The plurality of shock-absorbing portions 20 are arranged on the outer side wall of the body 10 of the shock pad 100 and are spaced apart along the circumferential direction of the body 10, and the first and second ends of the shock-absorbing portion 20 protrude from the body 10 to design a single stiffness structure. Further, as shown in Figure 2As shown, the damping pad 100 is located between the motor shaft coupling 200 and the worm shaft coupling 300, and is installed in cooperation with the clamping grooves of the motor shaft coupling 200 and the worm shaft coupling 300 through the damping portion 20. Optionally, during the installation of the damping pad 100, the first end of the damping portion 20 is in contact with the motor shaft coupling 200, the second end of the damping portion 20 is in contact with the worm shaft coupling 300, and the damping portion 20 is deformed under the action of the axial compression force of the motor shaft coupling 200 and the worm shaft coupling 300, so as to generate a certain axial pre-tightening force in the axial direction of the damping pad 100, without the need to provide the axial pre-tightening force by increasing the spring mechanism, thereby reducing the production cost. At the same time, the first end and the second end of the damping portion 20 protrude from the body 10, and the compression force borne by the damping portion 20 is difficult to be transmitted to the body 10, thereby reducing the influence of the rigidity of the body 10 on the damping portion 20.

[0038] When the motor shaft coupling 200 drives the worm 500 to rotate at a high speed, the noise, wear and tear and operation noise of the worm bearing 400 generated by the meshing and rubbing of the motor shaft coupling 200 and the worm shaft coupling 300 can be well alleviated under the action of the axial pre-tightening force. At the same time, the first end and the second end of the damping portion 20 are directly in contact with the motor shaft coupling 200 and the worm shaft coupling 300, without the need to construct a convex point structure on the first end and / or the second end of the damping portion 20, the damping portion 20 is designed as a single rigidity structure, the axial structure design of the damping pad 100 is simplified, and the rigidity of the damping portion 20 is greater than that of the convex point structure, so that the damping portion 20 can bear a larger axial compression force and is not easy to be crushed or worn, thereby improving the service life of the damping pad 100.

[0039] According to the damping pad 100 of the embodiment of the present application, a plurality of damping portions 20 are sequentially and spacedly arranged in the circumferential direction of the outer side wall of the body 10 of the damping pad 100, and the first end and / or the second end of the damping portion 20 protrudes from the body 10 in the axial direction of the damping pad 100, so that the damping portion 20 can provide the axial pre-tightening force without the need to provide the axial pre-tightening force by increasing the spring mechanism, thereby reducing the production cost. At the same time, it is not necessary to additionally provide a convex point structure on the first end and / or the second end of the damping portion 20, the axial structure design of the damping pad 100 is simplified, and the rigidity of the damping portion 20 designed as a single rigidity structure is greater than that of the convex point structure, so that the damping portion 20 can bear a larger compression force and is not easy to be crushed or worn, thereby improving the service life of the damping pad 100.

[0040] In some embodiments of the present application, as shown in Figure 1 Each damping portion 20 comprises a pressure receiving segment 21 and a connecting segment 22 connected between the pressure receiving segment 21 and the body 10.

[0041] Specifically, the compression section 21 of the shock-absorbing part 20 has opposite first and / or second ends protruding from the body 10, and the connecting section 22 is connected between the first and / or second end of the compression section 21 and the body 10. Taking the case where the first and second ends of the shock-absorbing part 20 are configured to protrude from the body 10 as an example, the connecting section 22 is arranged between the first end of the compression section 21 and the body 10, and the connecting section 22 is arranged between the second end of the compression section 21 and the body 10. In this way, the first and / or second end of the compression section 21 can protrude from the body 10, and the compression section 21 can be deformed under the axial compression force of the motor coupling 200 and the worm coupling 300, so as to generate a certain axial pre-tightening force in the axial direction of the shock-absorbing pad 100.

[0042] In some embodiments of the present application, as shown in Figure 1 In the axial direction of the shock-absorbing pad 100, the two ends of the compression section 21 are configured as compression planes.

[0043] Specifically, in the axial direction of the shock-absorbing pad 100, the opposite first and second ends of the compression section 21 are configured as compression planes. Optionally, the first end of the compression section 21 is in contact with the motor coupling 200, and the second end of the compression section 21 is in contact with the worm coupling 300. In this way, the axial pre-tightening force in the axial direction of the shock-absorbing pad 100 can be better provided, so as to alleviate the noise and wear caused by the meshing and rubbing between the motor coupling 200 and the worm coupling 300.

[0044] In some embodiments of the present application, as shown in Figure 1 In the axial direction of the shock-absorbing pad 100, at least one end face of the connecting section 22 is configured as an inclined plane.

[0045] Specifically, in the axial direction of the shock-absorbing pad 100, at least one end face of the connecting section 22 connected between the first and / or second end of the compression section 21 and the body 10 can be configured as an inclined plane. That is, only when the first end of the compression section 21 protrudes from the body 10, the end face of the connecting section 22 connected between the first end of the compression section 21 and the body 10 is configured as an inclined plane. Only when the second end of the compression section 21 protrudes from the body 10, the end face of the connecting section 22 connected between the second end of the compression section 21 and the body 10 is configured as an inclined plane. When the first and second ends of the compression section 21 both protrude from the body 10, the end face of the connecting section 22 connected between the first end of the compression section 21 and the body 10 and the end face of the connecting section 22 connected between the second end of the compression section 21 and the body 10 are both configured as inclined planes. In this way, not only the shock-absorbing pad 100 can be integrally formed, but also a certain height difference between the compression section 21 and the body 10 can be ensured, so as to facilitate the provision of the axial pre-tightening force.

[0046] In some embodiments of the present application, the end surface of at least one end of the connecting section 22 is configured as an arc surface which is concave towards the damping portion 20 along the axial direction of the damping pad 100.

[0047] Specifically, the end surface of at least one end of the connecting section 22 connected between the first end and / or the second end of the pressure receiving section 21 and the body 10 can also be configured as an arc surface which is concave towards the damping portion 20 along the axial direction of the damping pad 100, that is, only when the first end of the pressure receiving section 21 protrudes from the body 10, the end surface of the connecting section 22 connected between the first end of the pressure receiving section 21 and the body 10 is configured as an arc surface, only when the second end of the pressure receiving section 21 protrudes from the body 10, the end surface of the connecting section 22 connected between the second end of the pressure receiving section 21 and the body 10 is configured as an arc surface, and when both the first end and the second end of the pressure receiving section 21 protrude from the body 10, the end surface of the connecting section 22 connected between the first end of the pressure receiving section 21 and the body 10 and the end surface of the connecting section 22 connected between the second end of the pressure receiving section 21 and the body 10 are both configured as arc surfaces. Such an arrangement not only facilitates the integral molding of the damping pad 100, but also ensures a certain height difference between the pressure receiving section 21 and the body 10, thereby facilitating the provision of axial pre-tightening force.

[0048] In some embodiments of the present application, as shown in Figure 1 the cross-sectional area of the pressure receiving section 21 is the same along the radial direction of the damping pad 100.

[0049] Specifically, as shown in Figure 1 the cross-sectional area of the pressure receiving section 21 is the same from the first end to the second end, and each pressure receiving section 21 has the same cross-sectional area. Such an arrangement can ensure that each pressure receiving section 21 receives more uniform compression force, thereby ensuring that each pressure receiving section 21 can produce a more consistent compression amount, and further enabling the pressure receiving section 21 to provide better axial pre-tightening force along the axial direction of the damping pad 100, further relieving the noise and wear caused by the meshing and rubbing between the motor coupling 200 and the worm coupling 300.

[0050] In some embodiments of the present application, the pressure receiving surface has an anti-wear layer. That is, the pressure receiving surface of each pressure receiving section 21 is provided with an anti-wear layer. Such an arrangement can improve the wear resistance of the damping pad 100, relieve the wear caused by the meshing and rubbing between the damping pad 100 and the motor coupling 200 or the worm coupling 300, and thereby improve the service life of the damping pad 100.

[0051] In some embodiments of the present application, as shown in Figure 1 the side wall 23 of at least one damping portion 20 is provided with a reinforcing rib 231 along the circumferential direction of the body 10, and the reinforcing rib 231 extends along the axial direction of the body 10. Specifically, as shown in Figure 1As shown, optionally, the side wall 23 of each damping part 20 is provided with a reinforcing rib 231 in the circumferential direction of the body 10, and the reinforcing rib 231 extends in the axial direction of the body 10. In this way, the rigidity of the damping part 20 can be enhanced, so that the damping part 20 is not easily crushed or worn when subjected to a large axial compression force, and the service life of the damping pad 100 is further improved.

[0052] In some embodiments of the present application, the axial compression amount of the damping part is calculated by the formula: wherein H represents the theoretical compression amount of the damping part, F represents the axial compression force borne by the damping part, and P represents the rigidity of the damping part.

[0053] It should be noted that when designing the damping pad, the axial compression amount that it can bear needs to be considered. On the one hand, it is necessary to ensure that the damping pad will not be crushed due to excessive compression force, and on the other hand, it is necessary to ensure that the damping pad will not lose the axial pre-tightening function due to no axial compression amount under the limit tolerance. Therefore, it is particularly important to determine the axial compression amount that the damping pad can bear.

[0054] In the related art, as shown in Figure 1 The common damping pad is provided with a convex point structure in the axial direction, so it can be regarded as a series connection of two kinds of rigidity structures. The convex point is in contact with the shaft coupling. After being subjected to force, the compression deformation amount is mainly concentrated on the convex point due to the small rigidity of the convex point. The connection part between the main body of the damping pad and the convex point will also bear part of the deformation, but the deformation at this part is nonlinear. Therefore, it is difficult to determine the axial compression amount of the damping pad during design, and it can only be determined through repeated experiments. However, the experience value cannot accurately estimate the axial compression amount, and it needs to be verified repeatedly through later experiments, thereby causing a large waste of research and development resources.

[0055] Therefore, based on the single rigidity structure design of the damping pad 100 of the present application, a theoretical calculation method for the axial compression amount of the damping pad is provided. Specifically, taking the case that the first end and the second end of the damping part 20 are provided as the convex body 10 as an example, the pressure receiving section 21 of the damping part 20 is shaped like a cubic column, and there is a certain height difference between the damping part 20 and the body 10. Therefore, the compression force borne by the damping part 20 is difficult to be transmitted to the body 10, the influence of the body 10 on the rigidity of the damping part 20 is reduced, and the rigidity of the damping pad 100 can be equivalent to the rigidity of the damping part 20. The axial compression amount of the damping pad 100 can be estimated by calculating the theoretical compression amount of the damping part 20.

[0056] The specific calculation formula is as follows:

[0057] wherein H represents the theoretical compression amount of the damping part, F represents the axial compression force borne by the damping part, and P represents the rigidity of the damping part.

[0058] For example, takingFigure 1 As an example of the eight circumferentially arranged shock-absorbing portions 20 shown, the rigidity of the shock-absorbing portion 20 is the sum of the rigidity of the compressed sections 21 of the eight shock-absorbing portions 20, and the specific calculation formula is as follows:

[0059]

[0060] wherein E represents the elastic modulus of the shock-absorbing portion, a represents the length of the shock-absorbing portion, b represents the width of the shock-absorbing portion, and h represents the thickness of the shock-absorbing portion.

[0061] The elastic modulus E of the shock-absorbing portion is not only dependent on the material itself, but also related to the geometric shape of the shock-absorbing portion 20, and is usually expressed as follows:

[0062] E = i * G,

[0063] wherein i represents a geometric shape influencing factor, and G represents the shear elastic modulus of the shock-absorbing portion.

[0064] Further, i = 3.6 * (1 + 2.22 * S 2 ), wherein S represents the specific area, which is the ratio of the compressed surface of the shock-absorbing portion 20 to the free area, and the expression is as follows:

[0065] G = 0.117 * e 0.034*j ,

[0066] wherein j represents the hardness of the shock-absorbing portion.

[0067] In summary, the theoretical compression amount H of the shock-absorbing portion can be expressed as follows:

[0068]

[0069] As can be seen from the above formula, the theoretical compression amount H of the shock-absorbing portion is only related to the axial compression force F borne by the shock-absorbing portion, the length a of the shock-absorbing portion, the width b of the shock-absorbing portion, the thickness h of the shock-absorbing portion, and the hardness j of the shock-absorbing portion.

[0070] It should be noted that the above-mentioned theoretical calculation method of the axial compression amount of the shock-absorbing pad is applicable to the structural design of any shock-absorbing pad 100 with a single rigidity of the compressed surface, and the derived calculation formula can be adjusted according to the actual situation, which is not limited in the present application.

[0071] The dimensional tolerance in the assembly process of the motor coupling 200, the shock-absorbing pad 100 and the worm coupling 300 can cause the shock-absorbing portion 20 to have a maximum compression amount H max and a minimum compression amount H min , and the maximum compression amount H max and the minimum compression amount H min can be obtained through dimensional chain calculation, and the minimum compression amount H minIn order to provide sufficient axial compression force F, the axial compression force F of the damping part is optionally greater than or equal to 100 N, and the maximum compression amount H max In order to ensure that the damping part 20 is not crushed when subjected to an axial compression force, the axial compression force F of the damping part, the length a of the damping part, the width b of the damping part, the thickness h of the damping part, and the hardness j of the damping part are adjusted, and the maximum compression amount H max and the minimum compression amount H min The theoretical compression amount H of the damping part can be obtained.

[0072] Therefore, by using the above-mentioned theoretical calculation method of the axial compression amount of the damping pad 100, the axial compression amount of the damping pad 100 can be estimated in the theoretical design stage of the damping pad 100, and the problem of difficult determination of the axial compression amount of the damping pad 100 is effectively solved, and the waste of research and development resources caused by repeated tests is reduced.

[0073] According to the second aspect of the present application, the vehicle comprises the damping pad 100 as in the first aspect.

[0074] According to the vehicle of the present application, the damping pad 100 is provided, and a plurality of damping parts 20 are arranged in the circumferential direction of the outer wall of the body 10 of the damping pad 100, and the first end and / or the second end of the damping part 20 protrudes from the body 10 in the axial direction of the damping pad 100, so that the damping part 20 can provide axial pre-tightening force without increasing the spring mechanism, thereby reducing the production cost. At the same time, the damping part 20 does not need to be provided with a protruding point structure at the first end and / or the second end, thereby simplifying the axial structure design of the damping pad 100. In addition, compared with the protruding point structure, the single stiffness structure of the damping part 20 has greater stiffness and can withstand greater compression force, thereby improving the service life of the damping pad 100.
