Description

Technical Field

[0001] This utility model relates to the technical field of transfer cases, and in particular to a low-noise and shock-resistant transfer case suspension device. Background Technology

[0002] A transfer case is a device that distributes engine power, sending power to the rear axle or simultaneously to both axles. It's essentially a component of a four-wheel drive vehicle. With the development of four-wheel drive technology, transfer cases have continuously evolved. There are many ways to install a transfer case, with suspension mounting being a common method. Suspension helps to properly adjust the vehicle's center of gravity, allowing it to be more evenly distributed between the front and rear axles or on both sides. Therefore, suspension is crucial and requires a low-noise, vibration-damping transfer case suspension system.

[0003] However, most existing transfer case suspension systems have only average shock absorption and limited ability to assist in the distribution of the vehicle's center of gravity. Furthermore, such transfer cases generate significant noise, affecting the driving experience. Utility Model Content

[0004] The purpose of this utility model is to provide a low-noise and shock-resistant transfer case suspension device to solve the problems mentioned in the background art. Most of the existing low-noise and shock-resistant transfer case suspension devices have a relatively average shock absorption effect and a relatively average auxiliary effect on the distribution of the vehicle's center of gravity. Moreover, such suspension transfer cases generate a lot of noise, which affects the driving experience of the vehicle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-noise and shock-resistant transfer case suspension device, comprising a transfer case, a suspension mechanism at the lower end of the transfer case, and an installation mechanism at the lower end of the suspension mechanism;

[0006] The suspension mechanism includes a support plate, a lifting plate, a limit block, a screw, a steel cover, a shock-absorbing spring, a base, a housing, guide rails, damping rubber pads, and a support frame. The support plate is fixedly connected to the lower surface of the transfer case. The lifting plate is fixedly installed on the lower surface of the support plate. Limit blocks are provided at both ends of the lifting plate. A screw is provided at one end of the support plate. A steel cover is fixedly connected to one end of the screw. A shock-absorbing spring is fixedly connected to the lower end of the steel cover. The other end of the shock-absorbing spring is fixedly connected to the base. A housing is fixedly installed on one side surface of the base. Guide rails are fixedly installed at both ends of the housing. Damping rubber pads are adhered to the inner wall of the housing. A support frame is fixedly installed on one side surface of the base.

[0007] Preferably, the two ends of the shock-absorbing spring are fixedly connected to the steel cover and the base respectively, and the steel cover and the base form a telescopic structure through the shock-absorbing spring.

[0008] Preferably, the limiting block forms a sliding structure with the outer shell via a guide rail.

[0009] Preferably, one side of the damping rubber pad is adhered to the inner wall of the housing, and the other side is in contact with the lifting plate.

[0010] Preferably, the installation mechanism includes an installation block, a fixing groove, an installation frame, a receiving groove, a return spring, a fixing block, and a pull rod. An installation block is fixedly installed on one side surface of the support frame. Fixing grooves are formed on both sides of the installation block. An installation frame is connected to one end of the installation block. A receiving groove is formed on the inner wall of the installation frame. A return spring is fixedly installed on the inner wall of the receiving groove. A fixing block is fixedly connected to one end of the return spring. A pull rod is fixedly connected to one side surface of the fixing block.

[0011] Preferably, the fixing groove matches the size of the fixing block, and the fixing block and the mounting block form a locking structure through the fixing groove.

[0012] Preferably, the two ends of the return spring are fixedly connected to the mounting bracket and the fixing block, respectively, and the fixing block forms a telescopic structure with the mounting bracket through the return spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-noise and shock-resistant transfer case suspension device, through the arrangement of a support plate, lifting plate, limiting block, screw, steel cover, shock-absorbing spring, base, outer shell, guide rail, damping rubber pad, and support frame, when the transfer case vibrates during operation or when the vehicle vibrates, the vibrating transfer case will cause the support plate to press down. At this time, the screw will cause the steel cover to press down on the shock-absorbing spring. After being subjected to pressure, the shock-absorbing spring will generate an upward rebound force, producing a shock-absorbing effect. At the same time, when the support plate presses down, the lifting plate will also move downward, and the lifting plate will rub against the damping rubber pad, which will also play a certain role in shock absorption. In this way, the transfer case has a very good auxiliary effect on the distribution of the center of gravity, and the noise generated by the transfer case is very low, resulting in a better driving experience for the vehicle.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a low-noise and shock-resistant transfer case suspension device, including a transfer case 1, a suspension mechanism 2 is provided at the lower end of the transfer case 1, and an installation mechanism 3 is provided at the lower end of the suspension mechanism 2;

[0021] The suspension mechanism 2 includes a support plate 201, a lifting plate 202, a limiting block 203, a screw 204, a steel cover 205, a shock-absorbing spring 206, a base 207, a housing 208, a guide rail 209, a damping rubber pad 210, and a support frame 211. The support plate 201 is fixedly connected to the lower surface of the transfer case 1. The lifting plate 202 is fixedly installed on the lower surface of the support plate 201. Limit blocks 203 are provided at both ends of the lifting plate 202. A screw 204 is provided at one end of the support plate 201. One end of the base 4 is fixedly connected to a steel cover 205. A shock-absorbing spring 206 is fixedly connected to the lower end of the steel cover 205. The other end of the shock-absorbing spring 206 is fixedly connected to a base 207. A housing 208 is fixedly installed on one side of the base 207. Guide rails 209 are fixedly installed at both ends of the housing 208. Damping rubber pads 210 are adhered to the inner wall of the housing 208. A support frame 211 is fixedly installed on one side of the base 207. The support frame is connected via a support plate 201, a lifting plate 202, a limit block 203, and a screw 204. The steel cover 205, shock absorber spring 206, base 207, outer shell 208, guide rail 209, damping rubber pad 210, and support frame 211 are arranged so that when the transfer case 1 vibrates during operation or when the vehicle vibrates, the vibrating transfer case 1 will cause the support plate 201 to press down. At this time, the screw 204 will cause the steel cover 205 to press down the shock absorber spring 206. After being compressed, the shock absorber spring 206 will generate an upward rebound force, producing a shock absorption effect. At the same time, when the support plate 201 presses down, the lifting plate 211... 02 will also be moved downwards, and the outer wall of the lifting plate 202 will rub against the inner wall of the damping rubber pad 210, which will also play a certain role in shock absorption. In this way, the transfer case 1 has a very good auxiliary effect on the distribution of the center of gravity, and the noise generated by the transfer case 1 is very small, making the vehicle feel better. Secondly, when the lifting plate 202 moves up and down, the limiting block 203 will slide on the guide rail 209. The limiting block 203 can limit the lifting movement of the lifting plate 202 and the extension and retraction movement of the shock absorber spring 206.

[0022] Furthermore, the two ends of the shock-absorbing spring 206 are fixedly connected to the steel cover 205 and the base 207 respectively. The steel cover 205 and the base 207 form a telescopic structure through the shock-absorbing spring 206. With the setting of the shock-absorbing spring 206, the shock-absorbing spring 206 will generate an upward rebound force when it is subjected to downward pressure, so as to achieve the effect of shock absorption.

[0023] Furthermore, the limiting block 203 forms a sliding structure with the outer shell 208 via the guide rail 209. With the setting of the limiting block 203, when the lifting plate 202 moves up and down, the limiting block 203 will slide on the guide rail 209, which can limit the up and down movement of the lifting plate 202.

[0024] Furthermore, one side of the damping rubber pad 210 is bonded to the inner wall of the outer casing 208, and the other side is in contact with the lifting plate 202. With the setting of the damping rubber pad 210, the lifting plate 202 will rub against the damping rubber pad 210 when it is being lifted, which also has the effect of shock absorption.

[0025] Furthermore, the mounting mechanism 3 includes a mounting block 301, a fixing groove 302, a mounting bracket 303, a receiving groove 304, a return spring 305, a fixing block 306, and a pull rod 307. The mounting block 301 is fixedly mounted on one side surface of the support frame 211. Fixing grooves 302 are formed on both sides of the mounting block 301. One end of the mounting block 301 is connected to the mounting bracket 303. A receiving groove 304 is formed on the inner wall of the mounting bracket 303. A return spring 305 is fixedly mounted on the inner wall of the receiving groove 304. One end of the return spring 305 is fixedly connected to the fixing block 306. A pull rod 307 is fixedly connected to one side surface of the fixing block 306. The mounting block 301, fixing groove 302, mounting bracket 303, receiving groove 304, and return spring 305... The mounting bracket 303 is fixed to the vehicle by bolts or other means, and the mounting block 306 and the pull rod 307 are set up. When installing the transfer case 1, the mounting block 301 is aligned and placed into the mounting bracket 303. When the mounting block 301 is fully inserted into the transfer case 1, the mounting block 306 is no longer compressed. At this time, under the push of the return spring 305, the mounting block 306 will be pushed into the fixing groove 302. In this way, the mounting block 301 is fixed in the mounting bracket 303, and the installation of the transfer case 1 is completed. When disassembling, only the pull rod 307 needs to be pulled. The pull rod 307 pulls the mounting block 306 into the receiving groove 304. When the mounting block 306 leaves the fixing groove 302, the mounting block 301 can leave the mounting bracket 303, and the transfer case 1 can be removed.

[0026] Furthermore, the fixing groove 302 and the fixing block 306 are sized to match. The fixing block 306 and the mounting block 301 form a locking structure through the fixing groove 302. When the fixing block 306 is pushed into the fixing groove 302, the mounting block 301 will be fixed in the mounting bracket 303.

[0027] Furthermore, the two ends of the return spring 305 are fixedly connected to the mounting bracket 303 and the fixing block 306 respectively. The fixing block 306 forms a telescopic structure with the mounting bracket 303 through the return spring 305. With the setting of the return spring 305, when the fixing block 306 is not squeezed, the return spring 305 will take the fixing block 306 back to its original position.

[0028] Working principle: When the transfer case 1 vibrates during operation or when the vehicle vibrates, the vibrating transfer case 1 will cause the support plate 201 to press down. At this time, the screw 204 will cause the steel cover 205 to press down the shock absorber spring 206. The shock absorber spring 206 will generate an upward rebound force after being compressed, thus producing a shock absorption effect. At the same time, when the support plate 201 presses down, the lifting plate 202 will also be moved downward. The outer wall of the lifting plate 202 will rub against the inner wall of the damping rubber pad 210, which will also play a certain role in shock absorption. In this way, the transfer case 1 has a very good auxiliary effect on the center of gravity distribution, and the noise generated by the transfer case 1 is very low, resulting in a better driving experience. Secondly, when the lifting plate 202 moves up and down, the limit block 203 will slide on the guide rail 209. The limit block 203 can control the movement of the lifting plate 202. The lifting and lowering movement of the lowering plate 202 and the extension and retraction movement of the shock-absorbing spring 206 are limited. The mounting bracket 303 is fixed in the vehicle by bolts or other means. When installing the transfer case 1, the mounting block 301 is aligned and placed into the mounting bracket 303. When the mounting block 301 is fully inserted into the transfer case 1, the fixing block 306 is no longer squeezed. At this time, under the push of the return spring 305, the fixing block 306 will be pushed into the fixing groove 302. In this way, the mounting block 301 is fixed in the mounting bracket 303, and the installation of the transfer case 1 is completed. When disassembling, it is only necessary to pull the pull rod 307. The pull rod 307 pulls the fixing block 306 into the receiving groove 304. When the fixing block 306 leaves the fixing groove 302, the mounting block 301 can leave the mounting bracket 303, and the transfer case 1 can be disassembled.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
