Description

Technical Field

[0001] The utility model relates to the technical field of vehicle steering knuckles, in particular to a split drive steering knuckle for an independent axle. Background Technique

[0002] An automobile axle (also known as an axletree) is a key component connecting the wheels and the vehicle frame, usually connected to the vehicle frame (or a load-bearing body) through a suspension. Wheels are installed at both ends of the axle. The function of the axle is to bear the weight of the automobile and ensure the normal driving of the vehicle. The steering knuckle, also known as the "sheep's horn", is one of the important parts of the steering axle, which can make the automobile drive stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the load at the front part of the automobile, support and drive the front wheels to rotate around the kingpin to make the automobile turn.

[0003] The existing conventional steering knuckle can transmit and bear the load of the automobile, support and drive the steering wheel to rotate around the kingpin to make the automobile turn, and has no driving function. Moreover, the models required during the installation of the existing steering knuckle flange connected to the steering knuckle need to correspond to the model of the steering knuckle. Therefore, one steering knuckle can only be installed with one type of steering knuckle flange. In order to enable a steering knuckle to adapt to different types of steering knuckle flanges and further improve the versatility of the steering knuckle, based on this, a split drive steering knuckle for an independent axle is provided now, which can eliminate the drawbacks of the existing device.

The steering knuckle body 1 is successively provided with a first mounting hole 4, a second mounting hole 5, and a third mounting hole 6. The first mounting hole 4 is located on one side of the drive half shaft 7, the second mounting hole 5 is located below the drive half shaft 7, and the third mounting hole 6 is located above the drive half shaft 7. One end of the drive flange 8 close to the steering knuckle body 1 is provided with a first mounting mechanism for fixedly connecting the drive flange 8 and the steering knuckle body 1;

[0037] The first mounting mechanism includes: a spline cone sleeve 209 integrally formed at one end of the drive flange 8.

The inner wall of the stop gasket 207 is integrally formed with a moving clamping plate. A linear sliding groove for the moving clamping plate to slide is opened at the position where the limit collar 208 is connected to the moving clamping plate. Through the mutual cooperation of the moving clamping plate and the linear sliding groove, when the stop gasket 207 is sleeved on the outer wall of the limit collar 208, it can perform limit sliding along the outer wall of the limit collar 208, so as to prevent the stop gasket 207 from rotating on the outer wall of the limit collar 208;

[0038] A second mounting mechanism for fixedly connecting the spline cone sleeve 209 and the drive half shaft 7 is provided inside the spline cone sleeve 209;

[0039] In this embodiment, during installation, through the first mounting mechanism and the second mounting mechanism, the installation and fixation of the steering knuckle body 1 with the drive half shaft 7 and the drive flange 8 can be realized;

[0040] When the steering knuckle body 1 is installed on the vehicle frame, at this time, through the second mounting hole 5 and the third mounting hole 6, the steering knuckle body 1 can be rotatably connected to the vehicle. At the same time, through the first mounting hole 4, the steering knuckle body 1 can be rotatably connected to the tie rod on the vehicle. During use, the tie rod drives the steering knuckle body 1 to rotate around the centers of the second mounting hole 5 and the third mounting hole 6, so as to facilitate the steering of the drive flange 8. At the same time, through the drive half shaft 7, the drive flange 8 can be driven to rotate during the steering process of the drive flange 8;

[0041] When it is necessary to replace the first mounting mechanism, it is possible to replace the first mounting mechanism of different models for adaptation according to different models of the drive half shaft 7 while ensuring that the model of the steering knuckle body 1 remains unchanged, thereby further improving the versatility of the steering knuckle body 1;

[0042] In one embodiment, as Figure 3- Figure 5 As shown, the first mounting mechanism further includes:

[0043] A limiting component arranged outside the limiting collar 208, and the limiting component is used to squeeze and fix the stop washer 207;

[0044] The limiting component is a round nut 204 sleeved on the outer wall of the limiting collar 208. The limiting collar 208 is threadedly connected to the round nut 204. The round nut 204 is in contact with one end outer wall of the stop washer 207.

A support sleeve 203 is sleeved on the outer wall of the tapered roller bearing 202. A hole-type snap ring 2010 is provided at one end of the inner wall of the support sleeve 203. One end outer wall of the spline cone sleeve 209 is fixedly connected with an outer skeleton oil seal 2011. The outer skeleton oil seal 2011 is fixedly connected with the transmission flange 8. The outer skeleton oil seal 2011 is in contact with the outer walls of the tapered roller bearing 202 and the support sleeve 203. The tapered roller bearing 202 can be limited by the hole-type snap ring 2010, and the positions where the transmission flange 8 is connected to the tapered roller bearing 202 and the support sleeve 203 can be dust-proof and waterproof through the outer skeleton oil seal 2011;

[0047] A fixing component is arranged at one end of the support sleeve 203 away from the transmission flange 8, and the fixing component is used to fixedly connect the support sleeve 203 with the steering knuckle body 1.

[0048] In one embodiment, as Figure 2 - Figure 7As shown, the fixed component includes: a knuckle flange 206 integrally formed at one end of the support sleeve 203. The knuckle flange 206 is located at the end of the support sleeve 203 away from the transmission flange 8. The knuckle flange 206 is sleeved on the outer wall of the tapered roller bearing 202. A plurality of fixing bolts are circumferentially arranged on the outer side of the knuckle flange 206. All the plurality of fixing bolts penetrate through the knuckle flange 206 and are threadedly connected to the knuckle body 1. A positioning insertion ring 205 is integrally formed at the end of the knuckle flange 206 away from the support sleeve 203. The positioning insertion ring 205 is located outside the round nut 204 and the stop washer 207. The positioning insertion ring 205 penetrates into the interior of the knuckle body 1. An annular slot 201 for the positioning insertion ring 205 to slide is formed at the position where the knuckle body 1 is connected to the positioning insertion ring 205. The annular slot 201 is located outside one end of the fourth mounting hole 9. By inserting the positioning insertion ring 205 into the interior of the annular slot 201, the end faces of the knuckle flange 206 and the knuckle body 1 can be stably butted, effectively preventing the knuckle flange 206 from shifting during the installation process, thereby further improving the installation efficiency of the knuckle flange 206.

[0049] In one embodiment, as Figure 3 - Figure 8 shown, the second installation mechanism includes: a sealing component arranged inside the knuckle body 1. The sealing component is used for the sealed connection between the knuckle body 1 and the drive half shaft 7;

[0050] The sealing component is a sealing ring 302 installed on the inner wall of the fourth mounting hole 9. The sealing ring 302 is located at one end of the drive half shaft 7. The sealing ring 302 is in contact with the outer wall of the drive half shaft 7. The sealing ring 302 can prevent dust and water from entering the connection position between the drive half shaft 7 and the knuckle body 1;

[0051] A drive component is arranged at one end of the drive half shaft 7. The drive component is used for transmitting rotational power to the spline cone sleeve 209;

[0052] In one embodiment, as Figure 5 - Figure 7As shown in the figure, the transmission assembly includes: a first transmission shaft 301 fixedly connected to one end of the transmission half shaft 7. The first transmission shaft 301 passes through the fourth mounting hole 9 into the inner cavity of the spline cone sleeve 209. One end of the first transmission shaft 301 away from the transmission half shaft 7 is integrally formed with a second transmission shaft 303. A plurality of external splines are circumferentially and equidistantly formed on the outer wall of the second transmission shaft 303. Internal splines that mesh with the plurality of external splines are circumferentially and equidistantly formed on the inner wall of the spline cone sleeve 209. One end of the second transmission shaft 303 away from the first transmission shaft 301 is integrally formed with a third transmission shaft 304. The third transmission shaft 304 is located inside the transmission flange 8. The outer wall of one end of the third transmission shaft 304 away from the second transmission shaft 303 is frustum-shaped. Through the frustum-shaped outer wall, the third transmission shaft 304 can be conveniently passed through the steering knuckle body 1 into the inside of the limit collar 208;

[0053] A locking assembly is provided inside the transmission flange 8. The locking assembly is used to lock and fix the third transmission shaft 304;

[0054] In one embodiment, as Figure 5 - Figure 8 shown in the figure, the locking assembly includes: a first fixed collar 305 located inside the transmission flange 8. The first fixed collar 305 is in contact with the outer wall of one end of the spline cone sleeve 209. The first fixed collar 305 is sleeved on the outer wall of the third transmission shaft 304. A limit insertion block is fixedly connected to the inner wall of the first fixed collar 305. The outer wall of the top end of the limit insertion block is frustum-shaped. A positioning slot for the limit insertion block to slide is provided at the position where the third transmission shaft 304 is connected to the limit insertion block. One end of the first fixed collar 305 away from the spline cone sleeve 209 is integrally formed with a second fixed collar 307. A plurality of locking bolts 306 are circumferentially and equidistantly arranged on the outer side of the second fixed collar 307. All the plurality of locking bolts 306 pass through the second fixed collar 307 into the inside of the third transmission shaft 304. All the plurality of locking bolts 306 are threadedly connected to the third transmission shaft 304. Through the mutual cooperation of the limit insertion block and the positioning slot, when the first fixed collar 305 is sleeved on the outer wall of the third transmission shaft 304, it can be limited and slide along the outer wall of the third transmission shaft 304, thereby avoiding the situation of self-rotation of the first fixed collar 305 during the sliding process. By driving the second fixed collar 307 to move, the hole slots on the second fixed collar 307 are automatically aligned with the thread groove ports on the third transmission shaft 304, thereby further improving the locking efficiency of the third transmission shaft 304.

[0055] The above embodiments disclose a split drive steering knuckle for an independent axle. During installation, the drive flange 8 is pushed to insert the spline cone sleeve 209 into the interior of the support sleeve 203. At this time, the support sleeve 203 is rotatably connected to the spline cone sleeve 209 through the tapered roller bearing 202. Then, the stop gasket 207 is sleeved on the outer wall of the limit collar 208. During this process, the moving plate slides along the inner wall of the linear chute driven by the stop gasket 207. Then, the round nut 204 is rotated to be threadedly connected to the limit collar 208 until the round nut 204 presses and fixes the stop gasket 207, thereby enabling the convenient installation and fixation of the stop gasket 207;

[0056] Then, the steering knuckle flange 206 is pushed to contact the outer wall of the steering knuckle body 1. At this time, the positioning insert ring 205 is inserted into the inner cavity of the annular slot 201 under the push of the steering knuckle flange 206, so as to facilitate the convenient clamping and limiting of the steering knuckle flange 206. Then, the steering knuckle flange 206 can be fixed to one end of the steering knuckle body 1 through the fixing bolts, thereby realizing the installation and fixation of the steering knuckle body 1 and the drive flange 8;

[0057] Then, the drive half shaft 7 is pushed to drive the first transmission shaft 301 to move, so that the first transmission shaft 301 can penetrate the steering knuckle body 1 from the other end of the steering knuckle body 1 to the inner cavity of the spline cone sleeve 209. During this process, the second transmission shaft 303 drives the third transmission shaft 304 to move to the inside of the drive flange 8 under the push of the first transmission shaft 301. At the same time, the second transmission shaft 303 drives the external spline to engage with the internal spline on the inner wall of the spline cone sleeve 209 until the sealing ring 302 deforms under the extrusion of the drive half shaft 7, thereby enabling the convenient butt joint of the second transmission shaft 303 and the spline cone sleeve 209;

[0058] Then, the first fixing collar 305 is pushed to sleeve the outer wall of the third transmission shaft 304. During this process, the limit insert block is inserted into the interior of the positioning slot driven by the first fixing collar 305, so that the first fixing collar 305 can limit and sleeve the third transmission shaft 304 until the first fixing collar 305 contacts the outer wall of the spline cone sleeve 209. Then, the third transmission shaft 304 is fixed and locked through a plurality of locking bolts 306 passing through the second fixing collar 307 and threadedly connected to the third transmission shaft 304, thereby realizing the installation and fixation of the first transmission shaft 301 and the spline cone sleeve 209. At the same time, through the outer skeleton oil seal 2011 and the sealing ring 302, the tapered roller bearing 202 can be protected against dust, water, and oil, thereby improving the service life of the tapered roller bearing 202;

[0059] When the knuckle body 1 is installed on the vehicle frame, at this time, the knuckle body 1 can be rotatably connected to the vehicle through the second mounting hole 5 and the third mounting hole 6. At the same time, the knuckle body 1 can be rotatably connected to the tie rod on the vehicle through the first mounting hole 4. During use, the tie rod drives the knuckle body 1 to rotate around the centers of the second mounting hole 5 and the third mounting hole 6, so as to facilitate the steering of the transmission flange 8. At the same time, during the steering process of the transmission flange 8, the transmission half shaft 7 can drive the transmission flange 8 to rotate. At this time, the stop washer 207 can play a guiding and limiting role for the tapered roller bearing 202 and the first transmission shaft 301;

[0060] When it is necessary to replace the support sleeve 203, at this time, by performing the reverse operation on the above operations, the support sleeve 203 can be replaced by disassembling the knuckle flange 206, and it can be adapted by replacing the support sleeve 203 with different models according to different models of the transmission half shaft 7 while ensuring that the model of the knuckle body 1 remains unchanged, thereby further improving the versatility of the knuckle body 1.

[0061] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
