Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension, and in particular to a suspension spring pad for automobile shock absorbers. Background Technology

[0002] In the current design of automotive front and rear shock absorbers, rubber pads are conventionally used to protect the connection between the suspension coil spring and the vehicle body. After the suspension coil spring in the automotive shock absorber is manufactured into a finished product, the lower end ring is installed on the shock absorber rubber pad, and the rubber pad is then installed on the shock absorber through the rubber pad seat.

[0003] Because the parts are located in the chassis system of the vehicle, gaps can easily form on the contact surface of the body during vehicle movement. Sand, mud and other debris can enter between the spring and the rubber pad, causing them to rub against each other, damaging the surface coating of the spring, and in severe cases, even damaging the rigid base material of the spring. This leads to corrosion of the spring at the contact point and ultimately causes premature breakage of the spring. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a suspension spring pad for automobile shock absorbers that can prevent sand and mud from entering between the suspension spring and the pad.

[0005] To solve the above-mentioned technical problems, the present invention provides a suspension spring pad for an automotive shock absorber, comprising: a pad body, the pad body having an installation groove that mates with one end of a suspension spring, the installation groove including a starting groove and a lift groove, the starting groove mates with the end of the suspension spring, the lift groove mates with the lift portion of the suspension spring, the pad body extending with a baffle plate parallel to the bottom of the lift groove, the baffle plate mates with the inner side of the lift portion of the suspension spring, for covering the inner side of the lift portion of the suspension spring, thereby preventing sand and mud from entering between the lift portion of the suspension spring and the pad, and the space between the suspension spring and the installation groove is filled with glue.

[0006] Preferably, a glue groove is provided at the end of the lift groove away from the starting groove, and the glue groove is used to accommodate glue that overflows when the suspension spring is assembled with the mounting groove.

[0007] Preferably, the end of the lift groove away from the starting groove extends with an extension arc plate, which fits against a portion of the side of the suspension spring to receive the glue overflowing during the assembly of the suspension spring and the mounting groove, thereby guiding the glue to seal and bond the gaps between the suspension spring and the extension plate.

[0008] Preferably, the mounting groove is provided with multiple rows of clamping surfaces, each clamping surface including multiple clamping protrusions. The clamping surfaces elastically squeeze the suspension spring in the mounting groove through the clamping protrusions, thereby initially clamping the suspension spring in the mounting groove.

[0009] Preferably, a stop plate extends from the end of the starting groove away from the lift groove, the stop plate being used to block and position the end of the suspension spring.

[0010] Preferably, the outer side of the rubber pad body has multiple positioning posts, and the rubber pad body is connected to the rubber pad seat through the positioning posts.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting a baffle plate parallel to the bottom of the lift groove above the lift groove, the baffle plate fits against the inner side of the suspension spring lift section, forming a physical barrier, effectively preventing foreign objects such as sand and mud from entering the critical friction area between the spring lift section and the rubber pad, thereby preventing wear of the spring surface coating, corrosion of the substrate, and even early breakage caused by the intrusion of foreign objects.

[0013] 2. The suspension spring is bonded to the mounting groove with glue, and a glue channel and an extension arc plate are designed at the end of the lift groove. The glue channel contains excess glue that overflows during assembly, keeping it clean; the extension arc plate guides the overflowing glue to fill the potential gap between the spring and the extension arc plate, forming an additional sealing adhesive layer, further isolating external contaminants, and improving connection sealing and long-term reliability;

[0014] 3. The mounting groove features multiple rows of clamping protrusions that elastically compress and initially secure the suspension spring within the groove before the adhesive cures, effectively preventing displacement during assembly and ensuring accurate bonding. Simultaneously, the gaps created by the clamping protrusions allow for more adhesive to be absorbed, enhancing the final bond strength. The baffle plate at the end of the initial groove precisely positions and blocks the spring end, simplifying the installation process. Attached Figure Description

[0026] Example:

[0027] A suspension spring pad for an automotive shock absorber includes: a pad body 1, the pad body 1 having an installation groove that mates with one end of a suspension spring, the installation groove including a starting groove 2 and a lift groove 3, the starting groove 2 mates with the end of the suspension spring, the lift groove 3 mates with the lift portion of the suspension spring, and the pad body 1 extending with a baffle plate 4 parallel to the bottom of the lift groove 3, the baffle plate 4 mates with the inner side of the lift portion of the suspension spring, for blocking the inner side of the lift portion of the suspension spring, thereby preventing sand and mud from entering between the lift portion of the suspension spring and the pad. The relative movement between the suspension spring lift section and the mounting groove is significantly greater than the relative movement between the suspension spring end and the mounting groove. The relative movement between the suspension spring end and the mounting groove is very small, and virtually no sand or mud will enter between the suspension spring and the mounting groove from this point. Therefore, placing a baffle plate 4 only above the lift groove 3 can effectively prevent sand and mud from entering between the suspension spring and the mounting groove without significantly increasing the difficulty of installing the suspension spring and the rubber pad. Adhesive is filled between the suspension spring and the mounting groove to bond the suspension spring and the rubber pad together.

[0028] When the suspension spring is assembled with the mounting slot, some of the glue will be squeezed out of the mounting slot, which will affect the cleanliness of the rubber pad. By opening a glue groove 5 at the end of the lift groove 3 away from the starting groove 2, the glue groove 5 can accommodate the glue that overflows when the suspension spring is assembled with the mounting slot.

[0029] An extension arc plate 6 extends from the end of the lift groove 3 away from the starting groove 2. The extension arc plate 6 fits against the lower side of the suspension spring and is used to receive the glue overflowing when the suspension spring is assembled with the mounting groove, thereby guiding the glue to seal and bond the gap between the suspension spring and the extension arc plate.

[0030] refer to Figure 1 The mounting groove contains multiple rows of clamping surfaces 7, each including multiple closely connected clamping protrusions 8. The clamping surfaces 7, through the clamping protrusions 8, elastically press against the suspension spring in the mounting groove, initially clamping the suspension spring within the groove. This prevents displacement between the rubber pad body 1 and the suspension spring before the adhesive has cured. Furthermore, the multiple clamping surfaces 7, evenly distributed within the mounting groove, protrude beyond the groove surface, providing a certain gap between the suspension spring and the groove surface. This allows for more adhesive to be accommodated between the suspension spring and the mounting groove, stabilizing the connection between the suspension spring and the rubber pad.

[0031] The starting groove 2 extends away from the lift groove 3 and has a blocking plate 9, which is used to block and position the end of the suspension spring.

[0032] To facilitate the connection between the rubber pad body 1 and the rubber pad seat, multiple positioning posts 10 extend from the outer side of the rubber pad body 1, and the rubber pad body 1 is connected to the rubber pad seat through the positioning posts 10.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
