Description

Technical Field

[0001] The present invention relates to the technical field of shock absorbers, and particularly to a tension-type front shock absorber assembly for a motorcycle. Background Art

[0002] The suspension structure is a key component of a motorcycle and is crucial for buffering road unevenness and obstacles, affecting the riding comfort and handling safety. In the prior art, the suspension structure mainly includes a traditional double swing arm double shock absorber suspension. However, in this way, the swing arms and shock absorbers need to be arranged on both sides, with a complicated structure. Moreover, the upper part of the shock absorber is installed on the frame, and the lower part is installed on the swing arm. The impact of the rear wheel is directly transmitted to the frame, resulting in poor shock absorption effect. At the same time, since the shock absorber is generally installed vertically on the frame, during the shock absorption process, it may be damaged by the impact of external forces, increasing the later maintenance cost.

[0003] Therefore, it is necessary to improve the shock absorption structure in the prior art, which can enhance the shock absorption effect, thereby improving the riding comfort and handling safety, and reducing the impact on the inside of the shock absorber during use, prolonging the service life of the shock absorber. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a tension-type front shock absorber assembly for a motorcycle, which can enhance the shock absorption effect, thereby improving the riding comfort and handling safety, and reducing the impact on the inside of the shock absorber during use, prolonging the service life of the shock absorber.

[0005] The tension-type front shock absorber assembly of the motorcycle of the present invention includes a tension-type shock absorber and a support arm assembly. The tension-type shock absorber includes a shock absorption member and a four-link assembly. The four-link assembly is composed of four links that are single-degree-of-freedom hinged to each other end to end. During use, the upper end of the four-link assembly is single-degree-of-freedom hinged to the motorcycle steering column, and the lower end is single-degree-of-freedom hinged to the front wheel axle of the vehicle. The two ends of the shock absorption member are respectively connected between the front and rear links of the four-link assembly.

[0006] The support arm assembly includes a support arm and a swing rod. The upper end of the support arm is fixedly connected to the steering column, and one end of the swing rod is hinged to the lower end of the support arm, and the other end is hinged to the front wheel axle of the vehicle.

[0007] Further, the support arm is approximately arc-shaped and winds around the rear side of the front wheel.

[0008] Further, the swing rod is arranged approximately horizontally.

[0009] Further, the two ends of the shock absorption member are respectively single-degree-of-freedom hinged to the front and rear hinged positions of the links of the four-link assembly.

[0010] An installation seat is provided on the steering column, and the upper end of the four-link assembly is hinged to the installation seat;

[0011] A connection groove is provided at the lower end of the support arm, and one end of the swing rod is hinged to the connection groove.

[0012] Furthermore, the connecting rod includes a rod body and a hinge portion. The hinge portions of two adjacent connecting rods are respectively a hinge groove and a hinge head. The hinge head is inserted into the hinge groove to form a hinge.

[0013] Furthermore, the hinge head and the hinge groove have a set constraint area in the hinge rotation direction, and the rod body is tubular.

[0014] Furthermore, a shock-absorbing layer is provided between the side walls of the hinge head and the hinge groove;

[0015] The hinge head and the hinge groove are hinged through a hinge shaft, and a shock-absorbing bushing is sleeved outside the hinge shaft.

[0016] Furthermore, there are two sets of the tension-type shock absorber and the support arm assembly, and the two sets of the tension-type shock absorber and the support arm assembly are respectively arranged on the left and right sides of the front wheels;

[0017] A plurality of reinforcing ribs are provided between the support arm arranged on the left side of the front wheel and the support arm arranged on the right side of the front wheel, and the plurality of reinforcing ribs are arranged at intervals.

[0018] Furthermore, the shock-absorbing member includes a damping member and a shock-absorbing spring sleeved outside the damping member. When the damping member is stretched, the shock-absorbing spring is compressed;

[0019] Or, when the damping member is stretched, the shock-absorbing spring is stretched.

[0020] Furthermore, damping member hinge seats are fixedly provided on the connecting rods corresponding to both ends of the damping member, and both ends of the damping member are respectively hinged to the corresponding hinge seats.

[0021] Advantages of the present invention: For the tension-type front shock absorber assembly of the motorcycle of the present invention, the shock-absorbing member is installed on the motorcycle through the four-link assembly. When an external force acts on the wheel and causes it to lift upward, the four-link assembly is compressed, so that the force received by the shock-absorbing member can be decomposed, enabling the shock-absorbing member to receive a force from the axial direction. Compared with the prior art where the shock-absorbing member is placed in the up-and-down direction of the vehicle body, while improving the shock-absorbing effect, it can reduce the force received by the shock-absorbing member from other directions during the shock-absorbing process, reduce the possibility of damage to the shock-absorbing member, extend the service life of the shock-absorbing member, and at the same time, the four-link assembly can also play a buffering role during the movement process, further enhancing the shock-absorbing effect.

Detailed implementation manners

[0035] Figure 1 This is a schematic structural view of the tension-type front shock absorber assembly of the present invention when installed on a motorcycle, Figure 2 is Figure 1 a structural schematic diagram of Figure 3 a schematic structural view of the cooperation between the shock absorber member and the four-link assembly,Figure 4 is Figure 1 the right view of Figure 5 is a sectional view of the connection between the four-link assembly and the steering column, Figure 6 is a structural schematic diagram of the cooperation between the four-link assembly and the shock-absorbing members when there are three shock-absorbing members, Figure 7 is a structural schematic diagram of the shock-absorbing member, Figure 8 is a structural schematic diagram of the sleeve, Figure 9 is Figure 8 the sectional view taken along the A-A direction in Figure 10 is a structural schematic diagram of the cylinder block, as Figures 1 - 10 shown: The tension-type front shock absorber assembly of the motorcycle in this embodiment includes a tension-type shock absorber and a support arm assembly. The tension-type shock absorber includes shock-absorbing members 2 and a four-link assembly. The four-link assembly is composed of four links 1 that are hinged to each other at the head and tail with a single degree of freedom, and when in use, the upper end of the four-link assembly is hinged to the motorcycle steering column 7 with a single degree of freedom, and the lower end is hinged to the front wheel axle of the vehicle. The two ends of the shock-absorbing member 2 are respectively connected between the front and rear links of the four-link assembly;

[0036] The support arm assembly includes a support arm 12 and a swing rod 13. The upper end of the support arm 12 is fixedly connected to the steering column 7. One end of the swing rod 13 is hinged to the lower end of the support arm 12, and the other end is hinged to the front wheel axle of the vehicle. An installation seat is provided on the steering column. The upper end of the four-link assembly is hinged to the hinge groove of the installation seat through bolts and nuts. Of course, hinge holes for the bolts to pass through are provided on the hinge groove.

[0037] In this structure, up and down refer to the up and down direction relative to Figure 1 or the up and down direction of the motorcycle, and front and back refer to Figure 1 the left and right direction in Figure 6 or the front and back direction of the motorcycle. The single degree of freedom means that it will only rotate around the hinge axis and will not shift, such as shifting relative to the left and right direction of the motorcycle; the shock-absorbing member 2 has a pre-tightening force to resist front and back stretching. The four-link assembly forms a rhombus structure. The rhombus structure has a diagonal line in the front and back direction and divides the rhombus structure into an upper triangle and a lower triangle. The number of shock-absorbing members 2 can be set to several according to the use requirements, such as setting three, as Figure 6In this case, 1A is a connecting rod and 2A is a shock absorber. At this time, one shock absorber 2 is located within the upper triangle, and both ends of the shock absorber 2 are respectively connected to the middle positions of two connecting rods of the upper triangle. Another shock absorber 2 can be located at the diagonal in the front-back direction of the rhombus structure, and both ends of the shock absorber 2 are respectively connected near the hinge points at the front-back diagonal. The last shock absorber 2 can be located within the lower triangle, and both ends of the shock absorber 2 are respectively connected to the middle positions of two connecting rods of the lower triangle. Preferably, one shock absorber 2 is provided, that is, the shock absorber 2 is arranged at the diagonal in the front-back direction of the rhombus structure, so that the shock absorption effect is greatly improved compared with the prior art. The shock absorber 2 is generally a spring-damper shock absorber, generally including a cylinder block 202, a piston assembly, a shock absorption spring 203 and other structures. This is an application of the prior art and will not be elaborated here. When the wheel is subjected to an external force and the front wheel axle lifts upward, at this time, the four-link assembly is compressed and the force is decomposed, so that the shock absorber 2 receives a force from the axial direction, which can improve the shock absorption effect. At the same time, when the piston assembly moves, the friction and collision with the inner wall of the cylinder block 202 can be greatly reduced, the probability of damage to the shock absorber 2 can be reduced, and the service life of the shock absorber can be extended. During the shock absorption process, the four-link assembly can also play a certain role in shock absorption and buffering, so as to further improve the shock absorption effect.

[0038] In this embodiment, the support arm 12 is approximately arc-shaped and winds around the rear side of the front wheel. The support arm 12 is an arc-shaped structure that conforms to the outer contour of the front wheel, which is convenient for supporting the four-link assembly and also convenient for installing the fender. One end of the support arm 12 can be fixed to the steering column 7 by welding or bolt-fixed connection, and the cross-section of the support arm 12 is rectangular.

[0039] In this embodiment, the swing rod 13 is arranged approximately horizontally. The swing rod is arranged approximately horizontally relative to the ground, and the four-link assembly and the shock absorber 2 are arranged obliquely relative to the ground.

[0040] In this embodiment, both ends of the shock absorber 2 are respectively hinged to the front and rear hinge positions of the connecting rod 1 of the four-link assembly with a single degree of freedom; in this structure, when the four-link assembly and the shock absorber 2 are assembled as Figure 3 assembled, the shock absorber 2 is placed horizontally (relative to Figure 3Within the rhombus structure formed by the four-bar linkage assembly (in the left-right direction), the connecting rod I 3, the connecting rod II 4, the connecting rod III 5, and the connecting rod IV 6 are hinged end to end with a single degree of freedom to form a four-bar linkage assembly. The single-degree-of-freedom hinge ensures that the two ends of the shock absorber 2 can only rotate around the hinge axis and will not deflect, thus avoiding interference with other vehicle body components. The two ends of the shock absorber 2 can be hinged at the front and rear hinge positions of the connecting rod 1 of the four-bar linkage assembly, that is, the two ends are respectively hinged near the hinge joints of the connecting rod I 3 and the connecting rod II 4 and near the hinge joints of the connecting rod III 5 and the connecting rod IV 6. Or when the shock absorber 2 is a shock-absorbing spring, the two ends can be directly connected near the hinge joints of the connecting rod I 3 and the connecting rod II 4 and near the hinge joints of the connecting rod III 5 and the connecting rod IV 6. Therefore, the connection method between the shock absorber 2 and the four-bar linkage assembly can be set according to the structure of the shock absorber 2.

[0041] An installation seat is provided on the steering column 7, and the upper end of the four-bar linkage assembly is hinged to the installation seat; the connection structure is as Figure 5 shown. An opening groove is provided on the installation seat, and a hinge hole is provided in the opening groove. The upper end of the four-bar linkage assembly is inserted into the opening groove to form a hinge, so that the overall structure is compact.

[0042] A connection groove is provided at the lower end of the support arm 12, and one end of the swing rod 13 is hinged to the connection groove. A hinge hole for the hinge shaft 8 to pass through is provided on the connection groove. The connection groove is an opening groove. One end of the swing rod 13 is inserted into the connection groove and fixed by the hinge shaft 8 (a bolt shaft) and the lock nut 9 to form a hinge. Polytetrafluoroethylene is provided on the inner side wall of the connection groove and / or the outer side wall of one end of the swing rod 13 located in the connection groove. Since polytetrafluoroethylene has good wear resistance and self-lubricating properties, it can reduce the friction at the connection between the swing rod 13 and the support arm 12. A bushing can be sleeved outside the hinge shaft 8, thereby further improving the shock absorption effect.

[0043] In this embodiment, the connecting rod 1 includes a rod body and a hinge portion 101. The hinge portions 101 of two adjacent connecting rods 1 are respectively a hinge groove and a hinge head. The hinge head is inserted into the hinge groove to form a hinge. The hinge groove is a U-shaped opening groove. The connecting rod 1 is a three-section structure. Hinge holes for the hinge shaft 8 to pass through are provided on the hinge groove and the hinge head. The hinge portion 101 is provided at both ends of the rod body. Preferably, the hinge head of the connecting rod I 3 is inserted into the hinge groove of the connecting rod II 4 to form a hinge, the hinge head of the connecting rod II 4 is inserted into the hinge groove of the connecting rod III 5 to form a hinge, the hinge head of the connecting rod III 5 is inserted into the hinge groove of the connecting rod IV 6 to form a hinge, and the hinge head of the connecting rod IV 6 is inserted into the hinge groove of the connecting rod I 3 to form a hinge. Thus, the overall structure is simple. Compared with the hinge joints of two adjacent connecting rods 1 formed side by side, the lateral (relative to the left-right direction of the motorcycle) dimension of the four-bar linkage assembly can be reduced, saving installation space.

[0044] In this embodiment, the hinge joint and the hinge groove have a set constraint area in the hinge rotation direction, and the rod body is tubular. The cross-section of the hinge portion 101 is a structure similar to a water droplet shape (the top of the water droplet shape is truncated to form a shape similar to a water droplet), and the width of the shape similar to a water droplet gradually increases along the extension direction of the rod body, that is, the so-called constraint area. The hinge portion 101 has set dimensions in the length and width directions, which can prevent the hinge portion 101 from deflecting. Therefore, when the four-link assembly is compressed or restored to its original state, it can limit the movement of the hinge portion 101 in the left-right direction (relative to the left-right direction of the motorcycle), so that when the four-link assembly moves, the hinge portion 101 will not shift during rotation, that is, it will not shift in other directions of the motorcycle, such as the left-right direction, to avoid interference with other components of the motorcycle during movement.

[0045] In this embodiment, a shock-absorbing layer 10 is provided between the side walls of the hinge joint and the hinge groove; in this structure, the shock-absorbing layer 10 is made of polytetrafluoroethylene material and has the effects of wear resistance and self-lubrication. It can be directly vulcanized on the outer side wall of the hinge joint or / and the inner side wall of the hinge groove, so as to play a certain role in reducing friction.

[0046] The hinge joint and the hinge groove are hinged through a hinge shaft 8, and a shock-absorbing bushing 11 is sleeved outside the hinge shaft 8. The shock-absorbing bushing 11 can be a metal bushing or a plastic bushing, which is an application of the prior art and will not be elaborated here. The hinge shaft 8 is a bolt shaft, and bolts pass through the hinge holes on the hinge portion 101 one by one and are fixed by nuts to form a hinge. The shock-absorbing bushing 11 is located in the hinge hole. The hinge shaft 8 at the lower part of the four-link assembly is a wheel shaft. The cooperation relationship among the hinge shaft 8, the nut, and the hinge portion 101 can be referred to as Figure 5 shown.

[0047] In this embodiment, there are two sets of tension-type shock absorbers and support arm assemblies, and the two sets of tension-type shock absorbers and support arm assemblies are respectively arranged on the left and right sides of the front wheel; left and right refer to the left-right direction of the motorcycle. In this structure, the two sets of tension-type shock absorbers and support arm assemblies constitute the front shock absorption system of the motorcycle, so as to improve the shock absorption effect.

[0048] A plurality of reinforcing ribs 14 are provided between the support arm 12 arranged on the left side of the front wheel and the support arm 12 arranged on the right side of the front wheel, and the plurality of reinforcing ribs 14 are arranged at intervals. Both ends of the reinforcing rib 14 are welded to the two support arms 12 respectively. The reinforcing rib 14 is a plate-like structure, and three reinforcing ribs 14 can be provided or set according to actual use needs, so as to support the two support arms 12 and improve the load-bearing capacity of the support arm 12.

[0049] In this embodiment, the shock absorber 2 includes a damping member and a shock-absorbing spring 203 sleeved outside the damping member. When the damping member is stretched, the shock-absorbing spring 203 is compressed. In this structure, when both ends of the shock-absorbing spring 203 are mounted on the damping member, when the damping member is stretched, the shock-absorbing spring 203 is compressed, that is, both ends of the damping member extend in the left-right direction relative to Figure 1 in the left-right direction, and both ends of the shock-absorbing spring 203 are compressed in the left-right direction relative to Figure 1 to achieve shock absorption.

[0050] Alternatively, when the damping member is stretched, the shock-absorbing spring 203 is stretched. When both ends of the shock-absorbing spring 203 are mounted on the four-bar linkage assembly, when the damping member is stretched, the shock-absorbing spring 203 is also stretched to achieve shock absorption.

[0051] In this embodiment, damping member hinge seats 102 are fixedly provided on the links 1 corresponding to both ends of the damping member, and both ends of the damping member are respectively hinged to the corresponding hinge seats 102. The hinge seat 102 includes a hinge seat I and a hinge seat II. Hinge holes are provided on the hinge seat I and the hinge seat II. A hinge slot can be formed on the hinge seat I and the hinge seat II to form a hinge, or the hinge seat I and the hinge seat II are in a plate-like structure and are provided with hinge holes to directly form a hinge with the damping member. Of course, the hinge is formed by a hinge shaft 8 and a nut. The hinge seat I is arranged on the hinge portion 101 of the link II 4 (close to the hinge portion 101 of the link I 3), and the hinge seat II is arranged on the hinge portion 101 of the link III 5 (close to the hinge portion 101 of the link IV 6), so that the overall structure is compact.

[0052] In this embodiment, the damping member includes a sleeve 201, a cylinder block 202 and a piston assembly. One end of the sleeve 201 and one end of the cylinder block 202 are respectively hinged to the corresponding hinge seats 102. One end of the cylinder block 202 is slidably arranged in the sleeve 201. The piston assembly is located in the sleeve 201. The piston assembly includes a piston rod 212 and a piston connected to one end of the piston rod 212. The other end of the piston rod 212 is connected to the sleeve 201. The piston assembly is hermetically connected to the cylinder block 202. The piston is located in the cylinder block 202. One end of the piston rod 212 extends into the cylinder block 202 to be connected to the piston. The matching structure and manner of the piston assembly and the cylinder block 202 are applications of the prior art and will not be elaborated here. An installation seat I 210 is arranged at one end of the sleeve 201. One end of the sleeve 201 is open. An installation seat II 211 is provided at the end of the cylinder block 202 located outside the sleeve 201. The installation seat I 210 and the installation seat II 211 are respectively hinged to the hinge seat I and the hinge seat II.

[0053] The sleeve 201 is provided with a plurality of sliding grooves 204. An outer wall of one end of the cylinder block 202 located inside the sleeve 201 is provided with a plurality of sliding components that cooperate with the plurality of sliding grooves 204. The plurality of sliding components respectively extend out of the plurality of sliding grooves 204 and can be driven to slide along the sliding grooves 204. The sliding grooves 204 are axially formed along the sleeve 201 and a plurality of them are arranged at intervals in the circumferential direction of the sleeve 201. An outer wall of one end of the cylinder block 202 close to the hinge seat 102Ⅰ is provided with a sliding component that extends out of the sleeve 201. When the damping member extends, the sliding component is driven to slide along the sliding groove 204.

[0054] In this embodiment, a mounting component is threadedly connected to an outer wall of the rear end of the sleeve 201. The mounting component includes a spring seat Ⅰ205 and a fixing seat 206. The sliding component is close to the front end of the sleeve 201 and is arranged opposite to the mounting component. The sliding component includes a fixing block 208 and a spring seat Ⅱ209 arranged on the fixing block 208. One end of the damping spring 203 is connected to the spring seat Ⅱ209 of one of the sliding components, and the other end of the damping spring 203 is connected to the spring seat Ⅰ205. One end of the damping spring 203 is connected to the spring seat Ⅰ205, and the other end of the damping spring 203 is mounted on the spring seat Ⅱ209. Thus, when the damping member extends, the end of the damping spring 203 connected to the spring seat Ⅱ209 moves to the right along with the cylinder block 202, and the end of the damping spring 203 connected to the spring seat Ⅰ205 moves to the left along with the piston rod 212. Thus, when the damping member extends, the damping spring 203 is compressed. The mounting component further includes a locking member 207, which can be a structure similar to a nut. The spring seat Ⅰ205, the fixing seat 206, and the locking member 207 are arranged in sequence (the spring seat Ⅰ205, the fixing seat 206, and the locking member 207 are all annular structures and are threadedly connected to the threads provided on the outer wall of the sleeve 201). The spring seat Ⅰ205 and the spring seat Ⅱ209 are arranged opposite to each other. A plurality of sliding components are arranged at intervals in the circumferential direction of the sleeve 201, and the number is the same as that of the sliding grooves 204.
