Description

Technical Field

[0001] This application relates to the field of straddle-type vehicle technology, and in particular to a vehicle and its steering connection structure. Background Technology

[0002] A straddle-type vehicle, generally also known as a motorcycle, is controlled by the rider who manipulates the handlebars to steer the vehicle, thereby controlling its direction of travel and maintaining a stable ride.

[0003] In related technologies, the front wheel of a motorcycle is typically rotatably connected to the fork tube, with a fork connector plate attached to the top of the fork tube. The handlebars are rigidly connected to the fork connector plate via the handlebar connector plate. This configuration results in a rigid connection between the handlebar connector plate and the fork connector plate. When the vehicle bounces up and down or turns, the fork tube transmits the motion to the handlebars through the fork connector plate, thus affecting the riding comfort of the vehicle.

[0009] Furthermore, the steering pivot is mounted in the connecting sleeve at the front end of the frame via a bearing; a lower spring plate and a lower connecting plate of the spring plate are provided between the front fork connecting plate and the connecting sleeve, and the steering pivot passes through the lower spring plate and the lower connecting plate of the spring plate together; the connection points on the front and rear sides of the lower spring plate are connected to the lower connecting plate of the spring plate, the connection points on the left and right sides of the lower spring plate are connected to the front fork connecting plate, and the lower connecting plate of the spring plate abuts against the bearing.

[0010] Furthermore, the front fork connecting plate has grooves on both its upper and lower sides; the groove on the upper side of the front fork connecting plate corresponds to the upper spring plate, and the groove on the lower side of the front fork connecting plate corresponds to the lower spring plate.

[0011] Furthermore, the upper connecting plate of the spring sheet is provided with upper connecting plate protrusions corresponding to the connection points on the front and rear sides of the upper spring sheet, and the connection points on the front and rear sides of the upper spring sheet abut against the upper connecting plate protrusions; and / or,

[0013] Furthermore, the upper spring plate and the lower spring plate are connected to the fork connecting plate, the upper spring plate is connected to the upper connecting plate of the spring plate, and the lower spring plate is connected to the lower connecting plate of the spring plate by a screw connection structure.

[0014] Furthermore, clearance holes are provided on both sides of the upper connecting plate of the spring sheet and on both sides of the lower connecting plate of the spring sheet; each clearance hole is used to set the screw connection structure at the corresponding position.

[0015] Compared with the prior art, this application has the following advantages:

[0016] (1) The steering connection structure described in this application, by setting an upper connecting plate and an upper spring plate between the handlebar connecting plate and the fork connecting plate, can realize the steering connection between the handlebar connecting plate and the fork connecting plate by using the upper connecting plate and the upper spring plate, and can also realize the isolation between the fork connecting plate and the handlebar connecting plate by using the elastically deformable upper spring plate, thereby reducing the transmission of the movement of the fork connecting plate to the handlebar during the up-and-down bouncing and steering of the vehicle, which is conducive to improving the driving comfort of the motorcycle.

[0017] (2) By setting a steering pivot, it is possible to realize the transmission connection between the handlebar connecting plate and the upper connecting plate of the spring plate, so that the upper connecting plate of the spring plate can rotate synchronously with the handlebar connecting plate, and the steering force is transmitted between the handlebar connecting plate and the fork connecting plate through the upper spring plate.

[0018] (3) By setting a lower spring plate and a lower spring plate connecting plate below the front fork connecting plate, and making the lower spring plate abut against the bearing, the entire steering connection structure can be well supported and limited, and the stability of the steering connection structure in the vehicle can be guaranteed.

[0019] (4) By setting the grooves on the upper and lower sides of the front fork connecting plate, and making the grooves on the upper and lower sides correspond to the spring plates on the same side, the grooves can provide space for the deformation of the spring plates, which helps to ensure the design effect of the spring plates.

[0020] (5) By setting protrusions on the upper and lower connecting plates of the spring sheet and making the spring sheet abut against the protrusions, the protrusions can be used to make a certain gap between the spring sheet and the connecting plate of the spring sheet, and also provide space for the deformation of the spring sheet, thus ensuring the design effect of the spring sheet.

[0021] (6) Each spring leaf is connected to the fork connecting plate and to the corresponding spring leaf connecting plate by a screw connection structure. The structure is simple, easy to design, manufacture and connect, and can also ensure the reliability of the connection between the components and facilitate later maintenance and replacement.

[0022] (7) Setting clearance holes in the spring plate connection plate to set the corresponding screw connection structure can make the steering connection structure more compact as a whole and help reduce space occupation.

[0025] Furthermore, the lower rocker arm includes two forked arms; one end of the two arms is connected to the lower connecting plate of the front fork, and the other end of the two arms is connected to the frame respectively, and the shock absorber is connected between the two arms.

[0026] The vehicle described in this application, by having a steering connection structure as described above, provides good driving comfort.

[0027] In addition, the lower control arm is composed of two forked arms, with the shock absorber connected between the two arms, which makes the lower control arm as a whole "A" shape.

[0062] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0063] An embodiment of the first aspect of this utility model provides a steering connection structure that is applied to straddle-type vehicles such as motorcycles and realizes the connection between the handlebars and the fork tube 2 in the straddle-type vehicle. Moreover, the steering connection structure, through its innovative design, helps to improve the driving comfort of the straddle-type vehicle.

[0064] In related technologies, when riding a motorcycle, the rider controls the steering of the vehicle by manipulating the handlebars, thereby controlling the direction of travel and maintaining stable riding.

[0065] In traditional motorcycles, the front wheel is connected to the fork tube 2, and a fork connector 3 is typically attached to the top of the fork tube 2. The handlebars are rigidly connected to the fork connector 3 via the handlebar connector 1. Because the handlebar connector 1 is rigidly connected to the fork connector 3, during vertical movement and turning, the fork tube 2 transmits the motion to the handlebars via the fork connector 3, and ultimately to the rider's hands. This causes the rider's hands to shake with the movement of the motorcycle, thus affecting riding comfort.

[0066] In view of this, in order to overcome the shortcomings of the prior art, the steering connection structure of this embodiment combines... Figures 1 to 5As shown, in terms of overall design, the steering connection structure includes a handlebar connecting plate 1 for connecting the handlebars, a fork connecting plate 3 connected to the fork tube 2, and a spring plate 4 and an upper spring plate 5 located between the handlebar connecting plate 1 and the fork connecting plate 3.

[0067] The upper spring plate 5 has its front and rear connection points connected to the upper spring plate 4, and its left and right connection points connected to the front fork connection plate 3. The upper spring plate 4 is configured to rotate synchronously with the handlebar connection plate 1.

[0068] Therefore, by setting an upper connecting plate 4 and an upper spring plate 5 between the handlebar connecting plate 1 and the fork connecting plate 3, the handlebar connecting plate 1 and the fork connecting plate 3 can be connected for steering. At the same time, the elastically deformable upper spring plate 5 can isolate the fork connecting plate 3 and the handlebar connecting plate 1, reduce the transmission of the movement of the fork connecting plate 3 to the handlebar during the up-and-down bouncing of the vehicle and the steering process, and help improve driving comfort.

[0069] Based on the above overall introduction, specifically, combined with Figure 5 and Figure 6 As shown, in one optional embodiment of the upper spring plate 5, the outer contour of the upper spring plate 5 is rectangular and has a ring-shaped structure. With this configuration, the connection points on the front and rear sides of the upper spring plate 5 are located at the front and rear diagonal positions, and the connection points on the left and right sides of the upper spring plate 5 are located at the left and right diagonal positions. Furthermore, the four corners of the upper spring plate 5 can be chamfered to improve its refined appearance.

[0070] It is understood that the upper spring plate 5 is not limited to having a rectangular outer contour and being designed as a ring structure. For example, it can also be a circular ring structure. When set as described above, the connection points on the front and rear sides and the connection points on the left and right sides of the upper spring plate 5 are alternately and equidistantly distributed along the circumference of the upper spring plate 5, and are arranged in a front-to-back and left-to-right opposite manner.

[0071] In some of the exemplary implementations, the combination continues Figures 1 to 6 As shown, the handlebar connecting plate 1 is mounted at the front end of the frame 7 via the steering pivot 6; the steering pivot 6 passes through the fork connecting plate 3, the upper spring plate 5, the upper connecting plate 4 of the spring plate, and the handlebar connecting plate 1; the upper connecting plate 4 of the spring plate rotates synchronously with the handlebar connecting plate 1 via the steering pivot 6.

[0072] At this time, by setting the steering pivot 6, it is possible to realize the transmission connection between the handlebar connecting plate 1 and the upper connecting plate 4 of the spring plate, so that the upper connecting plate 4 of the spring plate can rotate synchronously with the handlebar connecting plate 1, and the steering force is transmitted between the handlebar connecting plate 1 and the fork connecting plate 3 via the upper spring plate 5.

[0073] In specific implementation, combined with Figures 3 to 6 As shown, as an optional embodiment of the connection between the handlebar connecting plate 1 and the spring plate connecting plate 4, in detail, the handlebar connecting plate 1 has a first collar 101 formed downwards, the spring plate connecting plate 4 has a second collar 402 formed upwards and fitted inside the collar, and the top of the steering pivot 6 has a flat square 601 formed. The flat square 601 is inserted into the handlebar connecting plate 1 and the spring plate connecting plate 4, so as to realize the synchronous rotation of the handlebar connecting plate 1 and the spring plate connecting plate 4 with the steering pivot 6.

[0074] In some of the exemplary implementations, combined with Figure 3 and Figure 4 As shown, the steering pivot 6 is mounted in the connecting sleeve 701 at the front end of the frame 7 via the bearing 702; a lower spring plate 9 and a lower connecting plate 8 are provided between the front fork connecting plate 3 and the connecting sleeve 701, and the steering pivot 6 passes through the lower spring plate 9 and the lower connecting plate 8; the connection points on the front and rear sides of the lower spring plate 9 are connected to the lower connecting plate 8, the connection points on the left and right sides of the lower spring plate 9 are connected to the front fork connecting plate 3, and the lower connecting plate 8 abuts against the bearing 702.

[0075] Therefore, by setting a lower spring plate 9 and a lower spring plate 8 below the front fork connecting plate 3, and having the lower spring plate 8 abut against the bearing 702, the entire steering structure can be well supported and limited, ensuring the stability of the steering connection structure in the vehicle. Simultaneously, when the vibration of the frame 7 is transmitted to the steering pivot 6 via the connecting sleeve 701, the lower spring plate 9 can effectively counteract the vibration of the frame 7, reducing vertical bouncing and the transmission of the movement of the connecting sleeve 701 to the handlebars during steering, further improving riding comfort.

[0076] It is understood that the bearing 702 has an inner ring and an outer ring. In order to enable the lower connecting plate 8 of the spring sheet to rotate smoothly when it abuts against the bearing 702, in detail, in this embodiment, the lower connecting plate 8 of the spring sheet is formed with a third ring 802 downward, and the third ring 802 abuts against the inner ring of the bearing 702.

[0077] In specific implementation, combined with Figure 9 and Figure 10As shown, similar to the structure of the upper spring plate 5, the lower spring plate 9 has a rectangular outer contour and is designed as a ring structure, with chamfered corners at all four apex positions. With this configuration, the connection points on the front and rear sides of the lower spring plate 9 are located at opposite corners, and the connection points on the left and right sides of the lower spring plate 9 are located at opposite corners of the upper spring plate 5. Of course, it is understood that the lower spring plate 9 is not limited to having a rectangular outer contour and a ring structure; it could also be a circular structure. In this case, the connection points on the front and rear sides and the connection points on the left and right sides of the lower spring plate 9 are alternately and equidistantly distributed along the circumference of the lower spring plate 9, and are arranged in a corresponding front-to-back and left-to-right configuration.

[0078] In some of the exemplary implementations, combined with Figures 3 to 5 ,as well as Figure 11 As shown, the front fork connecting plate 3 has grooves a on both the upper and lower sides; the groove a on the upper side of the front fork connecting plate 3 corresponds to the upper spring plate 5, and the groove a on the lower side of the front fork connecting plate 3 corresponds to the lower spring plate 9.

[0079] As shown above, by setting the grooves a on the upper and lower sides of the front fork connecting plate 3, and making the grooves a on the upper and lower sides correspond to the spring plates on the same side, the grooves a can provide space to avoid deformation of the spring plates, which helps to ensure the design effect of the spring plates.

[0080] In some of the exemplary implementations, combined with Figure 3 and Figure 9 As shown, the upper connecting plate 4 of the spring sheet is provided with an upper connecting plate protrusion 401 corresponding to the connection points on the front and rear sides of the upper spring sheet 5, and the connection points on the front and rear sides of the upper spring sheet 5 abut against the upper connecting plate protrusion 401; the lower connecting plate 8 of the spring sheet is provided with a lower connecting plate protrusion 801 corresponding to the connection points on the front and rear sides of the lower spring sheet 9, and the connection points on the front and rear sides of the lower spring sheet 9 abut against the lower connecting plate protrusion 801.

[0081] Therefore, by setting an upper connecting plate protrusion 401 on the upper connecting plate 4 and the lower connecting plate 8 of the spring sheet, and making the upper spring sheet 5 and the lower spring sheet 9 abut against the upper connecting plate protrusion 401, and similarly, the lower spring sheet 9 is connected to the lower connecting plate protrusion 801, the upper connecting plate protrusion 401 can make a certain gap between the upper spring sheet 5 and the upper connecting plate 4 of the spring sheet, and between the lower spring sheet 9 and the lower connecting plate 8 of the spring sheet, and can also provide space for the deformation of the upper spring sheet 5 and the lower spring sheet 9, thus ensuring the design effect of the upper spring sheet 5 and the lower spring sheet 9.

[0082] Combination Figure 7 , Figure 9 and Figure 11As shown, the upper connecting plate protrusion 401 on the upper connecting plate 4 of the spring sheet is only set at the connection points on the front and rear sides that connect with the upper spring sheet 5, and the lower connecting plate protrusion 801 on the lower connecting plate 8 of the spring sheet is also only set at the connection points on the front and rear sides that connect with the lower spring sheet 9.

[0083] In detail, in practical implementation, both the upper connecting plate protrusion 401 and the lower connecting plate protrusion 801 are annular. Simultaneously, the upper connecting plate protrusion 401 can be integrally formed with the upper connecting plate 4 of the spring plate, and the lower connecting plate protrusion 801 can be integrally formed with the lower connecting plate 8 of the spring plate. This arrangement facilitates the assembly of the steering connection structure. Of course, it is understood that the upper connecting plate protrusion 401 and the upper connecting plate 4 of the spring plate, and the lower connecting plate protrusion 801 and the lower connecting plate 8 of the spring plate, can also be separate components, but fixedly connected together.

[0084] In some exemplary embodiments, the upper spring plate 5 and the lower spring plate 9 can be connected to the fork connecting plate 3, the upper spring plate 5 to the upper connecting plate 4, and the lower spring plate 9 to the lower connecting plate 8 by a screw connection structure 10.

[0085] In this way, each spring leaf is connected to the fork connecting plate 3 and to the corresponding spring leaf connecting plate by a screw connection structure 10. The structure is simple, easy to design, manufacture and connect, and can also ensure the reliability of the connection between the components and facilitate later maintenance and replacement.

[0086] Combination Figure 7 and Figure 8 As shown in detail, the screw connection structure 10 can generally be a bolt. When using the screw connection structure 10 to connect the upper spring plate 5, the upper connecting plate 4 of the spring plate, and the front fork connecting plate 3, firstly, a pair of screw connections 10 are used to screw the upper spring plate 5 to the upper connecting plate 4 of the spring plate. Then, another pair of screw connections 10 are used to connect the upper spring plate 5 to the front fork connecting plate 3 from above the upper connecting plate 4 downwards through the upper connecting plate 4.

[0087] Combination Figures 9 to 11 As shown, similarly, when using the screw connection structure 10 to connect the lower spring plate 9, the lower spring plate connecting plate 8, and the fork connecting plate 3, firstly, a pair of screw connections 10 are used to screw the lower spring plate 9 to the lower spring plate connecting plate 8, and then another pair of screw connections 10 are used to screw the lower spring plate 9 to the fork connecting plate 3 from below the lower spring plate connecting plate 8 through the lower spring plate connecting plate 8.

[0088] In some of the exemplary implementations, combined with Figure 7 and Figure 11As shown, clearance holes b are provided on both sides of the upper connecting plate 4 of the spring sheet and on both sides of the lower connecting plate 8 of the spring sheet; each clearance hole b is used to set the corresponding screw structure 10. Thus, as described above, the upper screw structure 10 passes through the upper connecting plate 4 of the spring sheet to realize the connection between the upper spring sheet 5 and the front fork connecting plate 3, and the lower screw structure 10 passes through the lower connecting plate 8 of the spring sheet to realize the connection between the lower spring sheet 9 and the front fork connecting plate 3.

[0089] It is understandable that by setting clearance holes b on the upper connecting plate 4 and the lower connecting plate 8 of the spring sheet to set the screw connection structure 10 at the corresponding position, the steering connection structure can be made more compact overall, which helps to reduce space occupation.

[0090] Combination Figure 6 and Figure 11 As shown, the clearance hole b is used to accommodate the nut of the screw connection structure 10, and generally allows the nut not to protrude from the upper connecting plate 4 and the lower connecting plate 8 of the spring plate, thereby making the steering connection structure more compact as a whole. Furthermore, by hiding the nut inside the upper connecting plate 4 and the lower connecting plate 8 of the spring plate, it helps to improve the overall refinement of the steering connection structure.

[0091] It is worth noting that, regarding the steering connection structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 11 As shown, the steering connection structure includes a handlebar connecting plate 1 for connecting the handlebars, a fork connecting plate 3 connected to the fork tube 2, and a spring plate 4 and an upper spring plate 5 located between the handlebar connecting plate 1 and the fork connecting plate 3.

[0092] The upper spring plate 5 has its front and rear connection points connected to the upper spring plate 4, and its left and right connection points connected to the front fork connection plate 3. The upper spring plate 4 is configured to rotate synchronously with the handlebar connection plate 1.

[0093] Furthermore, the handlebar connecting plate 1 is mounted at the front end of the frame 7 via a steering pivot 6. The steering pivot 6 passes through the fork connecting plate 3, the upper spring plate 5, the upper spring plate connecting plate 4, and the handlebar connecting plate 1. Specifically, the upper spring plate connecting plate 4 rotates synchronously with the handlebar connecting plate 1 via the steering pivot 6. The handlebar connecting plate 1 has a first collar 101 formed downwards, and the upper spring plate connecting plate 4 has a second collar 402 formed upwards and fitted inside the collar. The top of the steering pivot 6 has a flat square 601, which is inserted into the handlebar connecting plate 1 and the upper spring plate connecting plate 4, thus achieving synchronous rotation of the handlebar connecting plate 1 and the upper spring plate connecting plate 4 with the steering pivot 6.

[0094] The steering pivot 6 is mounted in the connecting sleeve 701 at the front end of the frame 7 via a bearing 702. A lower spring plate 9 and a lower connecting plate 8 are located between the fork connecting plate 3 and the connecting sleeve 701, with the steering pivot 6 passing through both the lower spring plate 9 and the lower connecting plate 8. Furthermore, the connection points on the front and rear sides of the lower spring plate 9 are connected to the lower connecting plate 8, and the connection points on the left and right sides of the lower spring plate 9 are connected to the fork connecting plate 3. Simultaneously, the lower connecting plate 8 abuts against the bearing 702.

[0095] The fork connecting plate 3 has grooves a on both its upper and lower sides; the groove a on the upper side of the fork connecting plate 3 corresponds to the upper spring plate 5, and the groove a on the lower side of the fork connecting plate 3 corresponds to the lower spring plate 9. The upper connecting plate 4 of the spring plate has an upper connecting plate protrusion 401 corresponding to the connection points on the front and rear sides of the upper spring plate 5, and the connection points on the front and rear sides of the upper spring plate 5 abut against the upper connecting plate protrusion 401; the lower connecting plate 8 of the spring plate has a lower connecting plate protrusion 801 corresponding to the connection points on the front and rear sides of the lower spring plate 9, and the connection points on the front and rear sides of the lower spring plate 9 abut against the lower connecting plate protrusion 801.

[0096] The upper spring plate 5 and the lower spring plate 9 are connected to the front fork connecting plate 3, the upper spring plate 5 is connected to the upper connecting plate 4, and the lower spring plate 9 is connected to the lower connecting plate 8, all using screw connections 10. Meanwhile, clearance holes b are provided on both sides of the upper connecting plate 4 and the lower connecting plate 8, each clearance hole b being used to install the corresponding screw connection 10.

[0097] Furthermore, the threaded structure 10 can generally be made of bolts. The upper spring plate 5 and lower spring plate 9 can typically be made of spring steel. Obviously, by utilizing the high radial stiffness of the upper spring plate 5 and lower spring plate 9, when the handlebar connecting plate 1 rotates, the upper spring plate 5 can drive the front fork connecting plate 3, i.e., the front fork tube 2, to rotate via the steering pivot 6 and the upper connecting plate 4, thus achieving vehicle steering. The lower spring plate 9, on the one hand, utilizes its radial stiffness to provide support for the rotation of the front fork connecting plate 3, etc., and on the other hand, together with the upper spring plate 5, uses its own elastic deformation to reduce the transmission of movement from the front fork connecting plate 3 to the handlebar connecting plate 1.

[0098] Continue to combine Figures 1 to 5As shown, as an optional assembly form of the steering connection structure in this embodiment, the fork connecting plate 3 and the fork tube 2 are usually connected as a single unit. First, the lower spring plate 9 is connected to the lower spring plate connecting plate 8, and then the lower spring plate 9 is connected below the fork connecting plate 3. Next, the steering pivot 6 is passed sequentially through the fork connecting plate 3, the lower spring plate 9, and the lower spring plate connecting plate 8, and the steering pivot 6 is installed in the connecting sleeve 701 using a bearing 702. Then, the upper spring plate 5 and the upper spring plate connecting plate 4 are sequentially fitted onto the steering pivot 6, and the upper spring plate 5 is connected to the upper spring plate connecting plate 4, and then the upper spring plate 5 is connected above the fork connecting plate 3. Finally, the handlebar connecting plate 1 is connected to the flat section 601 of the steering pivot 6.

[0099] The steering connection structure of this embodiment adopts the above design. By setting an upper connecting plate 4 and an upper spring plate 5 between the handlebar connecting plate 1 and the front fork connecting plate 3, the steering connection between the handlebar connecting plate 1 and the front fork connecting plate 3 is realized. At the same time, the elastically deformable upper spring plate 5 isolates the front fork connecting plate 3 and the handlebar connecting plate 1, reducing the transmission of the movement of the front fork connecting plate 3 to the handlebar during the up-and-down bouncing of the vehicle and the steering process, which is conducive to improving driving comfort.

[0101] Specifically, in combination Figure 1 , Figure 12 and Figure 13 As shown, there are two fork tubes 2 arranged side by side, and a fork connecting plate 3 is connected between the tops of the two fork tubes 2. A fork lower connecting plate 11 is connected between the middle of the two fork tubes 2. The handlebar connecting plate 1 is rotatably mounted on the frame 7. A lower rocker arm 12 is hinged between the fork lower connecting plate 11 and the frame 7. A shock absorber 13 is hinged between the lower rocker arm 12 and the frame 7.

[0102] Combination Figure 8 and Figure 12 As shown, the fork tube 2 and the fork connecting plate 3 are typically detachably connected. Specifically, the fork connecting plate 3 has a through hole, into which the top end of the fork tube 2 is inserted and secured to the fork tube 2 using a nut. Furthermore, to effectively improve the connection reliability between the fork tube 2 and the fork connecting plate 3, a double nut with reverse tightening can be used.

[0103] Combination Figure 12As shown, the lower fork connecting plate 11 is fixed to the fork tube 2 by clamping. The connection between the lower fork connecting plate 11 and the fork tube 2 can be done using existing methods. Similarly, the shock absorber 13 can be a commonly available shock absorber. The type and connection method of the shock absorber 13 can be set using existing methods.

[0104] In some exemplary embodiments, the lower rocker arm 12 includes two forked arms 1201; one end of the two arms 1201 is connected to the lower connecting plate 11 of the front fork, and the other end of the two arms 1201 is connected to the frame 7 respectively, and the shock absorber 13 is connected between the two arms 1201.

[0105] The lower rocker arm 12 is composed of two forked support arms 1201. The shock absorber 13 is connected between the two support arms 1201, which makes the lower rocker arm 12 as a whole "A" shape. This facilitates the arrangement of the lower rocker arm 12 and gives the front suspension a better overall appearance quality while achieving the connection between the front suspension and the frame 7.

[0106] In this embodiment, the lower rocker arm 12 is composed of two support arms 1201. This facilitates the arrangement of the lower rocker arm 12 while ensuring the connection between the front suspension and the frame 7, and also gives the front suspension a better overall appearance. Furthermore, by equipping the vehicle with the steering connection structure described above, it also provides good driving comfort.
