Description
Technical Field
[0001] The present application relates to the technical field of automobile shock absorber accessories, and more specifically to a guide for an automobile shock absorber. Background Art
[0002] In order to improve the riding comfort, automobiles are generally equipped with automobile shock absorbers. When the frame and the axle make reciprocating relative motion, the piston rod of the automobile shock absorber also makes reciprocating motion in the cylinder body, and the damping force is provided by the shock-absorbing oil flowing between different chambers in the cylinder body to achieve the purpose of shock absorption. In order to prevent the piston rod from being significantly skewed during the reciprocating motion, the automobile shock absorber is usually provided with a guide, which is arranged at one end of the cylinder body, and the piston rod passes through the guide, and the piston rod is guided by the guide, and the oil seal at the end of the cylinder body is provided.
[0003] There is a guide for a car shock absorber, such as Figure 1 As shown, it includes a guide body 90 and a wear-resistant bushing 91 with a central hole 911. The guide body 90 has a receiving cavity 901, and the wear-resistant bushing 91 is arranged in the receiving cavity 901. Figure 2 The piston rod 92 passes through the guide body 90 and is slidably arranged in the center hole 911 of the wear-resistant bushing 91. By arranging the wear-resistant bushing 91 to replace the cavity wall of the accommodating cavity 901, the highly wear-resistant wear-resistant bushing 91 and the piston rod 92 achieve sliding friction through the shock-absorbing oil medium, so as to improve the overall life of the guide for the automobile shock absorber. However: Since there is an installation gap and oil-passing gap between the side of the piston rod 92 and the hole wall of the center hole 911, when the vehicle body is driving on a bumpy road, the piston rod 92 quickly moves up and down along the center hole 911. Figure 2 The above installation clearance and oil clearance make the piston rod 92 slightly skewed, and make the side of the piston rod 92 contact the two ends of the center hole 911 and the two sides that are symmetrical to the center. Figure 3 , so that both ends of the center hole 911 are in an expanded hole shape or at least one end is in an expanded hole shape, and the loss of the middle section of the center hole 911 is small. However, after the radial dimensions of both ends of the center hole 911 gradually increase, since the wear-resistant bushing 91 is integrally formed and the thickness at each location is equal, even if the loss of the middle section of the center hole 911 is small, the wear-resistant bushing 91 needs to be replaced as a whole, which wastes resources and increases the replacement cost.

[0029] Application Overview
[0030] There is a guide for an automobile shock absorber. Since there is an installation gap and an oil gap between the side of the piston rod and the wall of the center hole, when the vehicle body travels on a bumpy road, the piston rod quickly moves up and down along the center hole. The above-mentioned installation gap and oil gap cause the piston rod to be slightly skewed and cause the side of the piston rod to contact the two ends of the center hole and the two side surfaces that are centrally symmetrical. After long-term use, the two ends of the center hole are expanded, and the loss of the middle section of the center hole is small. However, after the radial dimensions of the two ends of the center hole gradually increase, since the wear-resistant bushing is integrally formed, even if the loss of the middle section of the center hole is small, the wear-resistant bushing needs to be replaced as a whole, resulting in a waste of resources and an increase in replacement cost.
[0031] Based on the above technical problems, the present application proposes a guide for an automobile shock absorber, wherein the guide for the automobile shock absorber has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the guide for the automobile shock absorber provided by the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0035] It should be noted that the piston rod passes through the guide body 10 and is slidably arranged in the first through hole 2021. By making the wear-resistant part 202 detachably connected to the seat body 201, when the wear-resistant part 202 is severely worn, the wear-resistant part 202 can be replaced. Since it is a partial replacement, the replacement cost is low; in addition, by making the thickness of the wear-resistant part 202 at one end close to the orifice of the mounting hole 2011 greater than the thickness of the other end of the wear-resistant part 202, that is, more material is used in the area where the wear-resistant part 202 is easily worn, and less material is used in the position where the wear-resistant part 202 is less worn, thereby achieving full utilization of materials. Compared with the prior art, since the thickness of the wear-resistant bushing is equal at each location, the two ends of the first through hole 2021 are expanded after a certain period of use and the middle section is less worn. The embodiment of the present application has the advantages of saving resources and helping to reduce replacement costs.
[0036] Furthermore, in order to realize the installation hole 2011, the wear-resistant part 202 is provided in the installation hole 2011, and the thickness of the two ends of the wear-resistant part 202 is different. Figure 4As shown, each of the mounting holes 2011 includes a tapered hole portion 20111 and a column hole portion 20112, the two mounting holes 2011 are symmetrically arranged, and the ends of the two tapered hole portions 20111 away from the column hole portion 20112 are collinear, and the collinear positions of the two tapered hole portions 20111 are located in the middle section of the mounting hole 2011, and the other ends of the tapered hole portions 20111 are connected to the corresponding column hole portions 20112, and the two column hole portions 20112 are respectively located at the two end portions of the mounting hole 2011; in addition, each of the two ends of the wear-resistant part 202 has a contact portion 2022 and a mounting portion 2023. The radial dimension of the contact portion 2022 from one end away from the mounting portion 2023 gradually increases to the other end, and the mounting portion 2023 is fixedly connected to the column hole portion 20112 by means of screw connection.

[0037] It should be noted that when replacing the wear-resistant member 202 near the bottom end of the accommodating cavity 101, the seat body 201 needs to be removed. Therefore, the seat body 201 and the guide body 10 are fixedly connected in a detachable manner. More specifically, in the embodiment of the present application, in order to achieve the fixed connection between the seat body 201 and the guide body 10, Figure 4 As shown, the side surface of the seat body 201 facing away from the wear-resistant part 202 has a plurality of first fixing holes 2012, and the side surface of the guide body 10 has a plurality of second fixing holes 102, the second fixing holes 102 extend from the side surface of the guide body 10 to the central axis direction of the guide body 10 by a predetermined distance and are connected with the accommodating cavity 101, and the second fixing holes 102 correspond one-to-one with the first fixing holes 2012, when the seat body 201 is placed in the accommodating cavity 101, each of the first fixing holes 2012 is directly opposite to the corresponding second fixing hole 102, when the external screws are screwed into the first fixing holes 2012 and the second fixing holes 102, the seat body 201 is connected to the guide body 10, and after loosening the external screws, the maintenance personnel can remove the seat body 201 and replace the worn wear-resistant part 202.
[0038] Furthermore, in order to facilitate the installation personnel to place the base body 201 into the accommodating cavity 101, the first fixing hole 2012 is aligned with the second fixing hole 102.

In the embodiment of the present application, the number of the positioning grooves 103 and the extension portions 2013 are both two, and each of the positioning grooves 103 is provided with an extension portion 2013. When the extension portion 2013 is placed in the positioning groove 103, each of the first fixing holes 2012 is directly opposite to the corresponding second fixing hole 102, and the end face of the seat body 201 away from the extension portion 2013 abuts against the bottom wall of the accommodating cavity 101.
[0039] Furthermore, if Figure 4 As shown, the guide body 10 also has an active cavity 104, and the active cavity 104 extends a predetermined distance from the bottom of the accommodating cavity 101 in the direction away from the cavity opening of the accommodating cavity 101, and the maximum radial dimension of the active cavity 104 is smaller than the maximum radial dimension of the accommodating cavity 101 and the seat body 201; in addition, the guide for the automobile shock absorber includes an oil scraper ring 30, and the oil scraper ring 30 is placed in the active cavity 104. By setting the active cavity 104, a space is provided to prevent the oil scraper ring 30 from being damaged; in addition, the oil scraper ring 30 has a second through hole 301, and the second through hole 301 is provided. The hole 301 is coaxially arranged with the first through hole 2021, and the piston rod passes through the second through hole 301, that is, the scraper ring 30 is sleeved on the piston rod. When the piston rod moves up and down, the scraper ring 30 moves up and down with the piston rod under the action of friction, and abuts against the bottom of the active cavity 104 or the seat body 201 at a certain moment and does not move further. At this time, since the piston rod is still moving in the original direction, the scraper ring 30 in a stationary state will scrape off the excess damping oil on the side of the moving piston rod to ensure that the thickness of the damping oil on the side of the piston rod is uniform. In addition, in the embodiment of the present application, the end faces of the two ends of the scraper ring 30 have a plurality of oil grooves (not marked in the figure), the side of the scraper ring 30 is spaced a predetermined distance from the cavity wall of the active cavity 104, and the thickness of the scraper ring 30 is less than the depth of the active cavity 104.

[0041] Furthermore, after the shock absorber oil flows out from the second through hole 301, in order to allow the outflowing shock absorber oil to flow back into the oil storage chamber of the outer cylinder of the automobile shock absorber, Figure 4 and Figure 5 As shown, the guide body 10 also has a third through hole 105, a transfer cavity 106 and a plurality of discharge ports 1061, the third through hole 105 is coaxially arranged with the first through hole 2021, the transfer cavity 106 is located at the end of the third through hole 105 away from the wear-resistant component 20, the discharge port 1061 extends from the cavity wall of the transfer cavity 106 in a direction away from the central axis of the guide body 10 and passes through the guide body 10, and the distance from the end of the discharge port 1061 away from the transfer cavity 106 to the central axis of the guide body 10 is greater than the distance from the side of the end of the guide body 10 where the wear-resistant component 20 is provided to the central axis of the guide body 10. It should be noted that the piston rod passes through the third through hole 105. When the shock absorber oil passes through the third through hole 105 from the second through hole 301 and flows into the transfer chamber 106, it flows back to the outer cylinder oil storage chamber of the automobile shock absorber through the discharge port 1061. Further, in order to facilitate the engagement of the end of the guide body 10 away from the wear-resistant component 20 with the external seal, Figure 4 and Figure 5 As shown, the end of the guide body 10 away from the wear-resistant component 20 has an annular protrusion 107.
