Description

[Technical Field]

[0001] The present invention relates to a vehicle and a vehicle part. [Background technology]

[0002] In recent years, efforts to significantly reduce waste generation have been gaining momentum. To achieve this, research and development is being conducted to reduce the stress on vehicle parts and improve their durability. Saddle-ride vehicles such as scooters are equipped with a modular engine structure (also called a power unit) that integrates the engine as the drive source, the swing arm of the suspension, and the drive system that drives the drive wheels. Such a power unit is attached via a link member that is rotatably supported on the body frame. A gusset that rotatably supports the link member is provided on the body frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2022 / 102205 Summary of the Invention [Problem to be solved by the invention]

[0004] The gusset described in Patent Document 1 is integrally formed by bending a metal plate. The gusset described in Patent Document 1 has a stopper portion that contacts the link member formed as an integral part. Therefore, for design reasons, it is necessary to cut out the vicinity of the stopper portion. To increase the rigidity of the cutout portion, the wall thickness is increased, which can result in increased weight. Furthermore, because the stopper portion of the gusset described in Patent Document 1 is integrally formed, there are cases where design freedom is limited.

[0005] The present invention aims to provide a vehicle and vehicle parts that can distribute stress applied to gussets that rotatably support an engine, improve the rigidity of the vehicle body, and increase the degree of freedom in design, and also contribute to a significant reduction in waste. [Means for solving the problem]

[0006] As a means for solving the above problem, a first aspect of the present invention is a vehicle (1) comprising a gusset (G) attached to a body frame (F) and a link member (L) that rotatably supports a power unit (P) including a drive source, wherein the gusset (G) rotatably supports the link member (L) and is provided with a stopper portion (G10) that abuts against the link member (L) and restricts the rotation range of the link member (L), and the stopper portion (G10) is provided as a separate part from the gusset (G).

[0007] According to this configuration, since the stopper portion is provided as a separate part from the gusset, the stress acting on the gusset can be dispersed, and the degree of freedom in design can be improved.

[0008] A second aspect of the present invention is that, in the first aspect, the stopper portion (G10) includes a rear wall (G11A, G12A) that abuts against the link member (L) at the rear side in the vehicle longitudinal direction, and a pair of side walls (G11B, G12B) in the vehicle width direction that extend from the rear wall (G11A, G12A) to the front side in the vehicle longitudinal direction and abut against the gusset (G), and front edges (G11C, G12C) on the front side in the vehicle longitudinal direction of the side walls (G11B, G12B) may be fixed to the gusset (G).

[0009] With this configuration, the front edges of the side walls, which are the fixing points, are spaced forward from the rear wall, so that the stress acting on the gusset can be efficiently dispersed.

[0010] A third aspect of the present invention is the second aspect, wherein the stopper portion (G10) may include a reinforcing wall (G12D) that connects the pair of side walls (G11B, G12B) together.

[0011] This configuration can improve the rigidity of the gusset and the stopper portion.

[0012] A fourth aspect of the present invention is that, in the second or third aspect, the gusset (G) includes a link connection portion (L2) that rotatably connects the link member (L), and the stopper portion (G10) is composed of an upper stopper portion (G11) that is attached above the link connection portion (L2) in the gusset (G) and abuts against the link member (L), and a lower stopper portion (G12) that is attached below the link connection portion (L2) in the gusset (G) and abuts against the link member (L), and the lower stopper portion (G12) may include a reinforcing wall (G12D) that connects the upper edges of the pair of side walls (G11B, G12B).

[0013] This configuration can improve the rigidity of the gusset near the link connection portion (L2).

[0014] A fifth aspect of the present invention is any one of the second to fourth aspects, wherein the rear wall (G11A, G12A) may have a protrusion (G11T, G12T) that protrudes rearward compared to the rear edge of the gusset (G) on the rear side in the vehicle fore-and-aft direction when viewed from the side of the vehicle.

[0015] According to this configuration, the protrusion amount and angle of the protrusion can be adjusted as desired, so that the stopper portion can be reliably brought into contact with the link member.

[0016] A sixth aspect of the present invention is any one of the first to fifth aspects, wherein the gusset (G) comprises an inner gusset (G1) located on the inner side in the vehicle width direction and an outer gusset (G2) located on the outer side in the vehicle width direction.

[0017] According to this configuration, the gusset is formed separately, which improves the degree of freedom in design.

[0018] A seventh aspect of the present invention is any one of the first to sixth aspects, wherein the gusset (G) may include a reinforcing member (G2S) extending along the longitudinal direction.

[0019] This configuration can improve the strength of the gusset.

[0020] An eighth aspect of the present invention is a vehicle part that is attached to a body frame (F) of a vehicle (1), and includes: a gusset (G) that rotatably supports a link member (L) that supports a power unit (P) including a drive source; and a stopper portion (G10) that is provided on the gusset (G) and abuts against the link member (L) to regulate the rotation range of the link member (L), wherein the stopper portion (G10) is provided as a separate part from the gusset (G).

[0021] According to this configuration, since the stopper portion is provided as a separate part from the gusset, the stress acting on the gusset can be dispersed, and the degree of freedom in design can be improved. [Effects of the Invention]

[0022] According to the present invention, it is possible to distribute stress acting on a gusset that rotatably supports an engine, improve the rigidity of the vehicle body, and increase the degree of freedom in design. [Brief explanation of the drawings]

[0024] As shown in FIG. 1, the vehicle 1 is, for example, a motorcycle or a three-wheeled motor vehicle. The vehicle 1 is a saddle-ride type motorcycle. The vehicle 1 may also be a three-wheeled motor vehicle having two wheels, either front or rear. In the following description, the vehicle front-rear direction, with the front side being the front and the rear side being the rear as seen from the driver along the traveling direction of the vehicle 1, the vehicle left-right direction (also referred to as the vehicle width direction), and the vehicle up-down direction are set as appropriate. The vehicle 1 is also referred to as the vehicle body as appropriate. The vehicle 1 includes, for example, a body frame F that supports a front wheel WF and a rear wheel WR, and a power unit P supported by the body frame F.

[0025] The body frame F is formed, for example, by combining steel pipes to provide high rigidity. The front wheel WF is, for example, a disc wheel, a wire wheel, or an integrally molded spoke wheel. The front wheel WF is rotatably supported by the lower ends of a pair of left and right front forks R. The front forks R are attached to a steering stem S that allows the front wheel WF to rotate in the steering direction (left and right). The steering stem S is supported by the body frame F to be rotatable in the left and right directions. A handlebar H extending in the left and right directions is fixed to the upper part of the steering stem S. A pair of left and right front rearview mirrors M are also fixed to the handlebar H.

[0026] A power unit P that generates driving force is rotatably fixed to the lower part of the body frame F. The power unit P is rotatably supported relative to the body frame via gussets G provided on the body frame. The gussets G will be described later. The power unit P has a modular engine structure that integrates an engine as a driving source, a drivetrain having a transmission T that reduces the rotation of the engine and outputs it, and a swing arm of the suspension. Inside the transmission T, for example, a mechanical continuously variable transmission is provided that eliminates the need for gear shifting operations.

[0027] The transmission T is provided on the left side in the left-right direction of the vehicle body. The transmission T has a case T1 that covers the continuously variable transmission. This case T1 functions as a swing arm of the suspension. The case T1 is supported by a damper device D that is connected to the body frame F. The power unit P is integrally provided with a swing arm unit (not shown) that houses a mechanism that drives the rear wheels and also serves as a suspension device. The swing arm unit supports the rear wheel WR rotatably on one side, for example, on the left side of the vehicle 1. The swing arm unit is supported on the body frame F by the damper device D.

[0028] A muffler (not shown) connected to an exhaust pipe through which exhaust gas flows is provided behind the power unit P. The muffler is provided on the right side of the vehicle body in the left-right direction. The muffler is fixed to the power unit P and rotates relative to the body frame F in conjunction with the power unit P. The power unit P has a cooling device (not shown) of either a forced air-cooling type that uses the rotational power of the engine or a water-cooling type.

[0029] A rear wheel WR is rotatably supported at the rear end of the case T1. The rear wheel WR is, for example, a disc wheel, a wire wheel, or an integrally molded spoke wheel. A tire of the same size as or different from that of the front wheel WF is attached to the rear wheel WR. The rear wheel WR is driven by a drive belt provided in a continuously variable transmission provided inside the case T1. The drive belt transmits the rotational driving force generated in the power unit P to the rear wheel WR via an automatic centrifugal clutch (not shown) provided inside the swing arm unit.

[0030] A vehicle seat 10 on which a driver sits is provided on the vehicle body frame F. The vehicle seat 10 is arranged at a seating position on the vehicle body frame F. A vehicle body cover 2 that covers the vehicle body frame F is provided between the underside of the vehicle seat 10 and the steering stem S. A step 20 on which the soles of the driver's feet rest is provided below the vehicle seat 10 and between the vehicle seat 10 and the steering stem S. A tandem step ST is provided below the vehicle seat 10 on which the soles of the feet of a tandem passenger seated behind the vehicle seat 10 rest.

[0031] As shown in Figures 2 and 3, a pair of left and right gussets G and link members L are attached to the body frame F. In the example of Figure 2, the gusset G and link member L arranged on the left side in the vehicle width direction are shown as viewed obliquely from the rear. The gusset G and link member L arranged on the left side will be described below. The gusset G and link member L arranged on the right side are configured to be plane symmetrical with the gusset G and link member L arranged on the left side in the vehicle width direction. The gusset G rotatably supports the link member L.

[0032] The link member L is a member that rotatably supports the power unit P including a drive source. The link member L includes, for example, a pair of left and right pressing portions L3 in the vehicle width direction, and a pair of left and right power unit support portions L10 in the vehicle width direction that rotatably support the power unit P. The pressing portions L3 include an inner pressing plate L4 located on the inner side of the body frame F in the vehicle width direction, an outer pressing plate L5 located on the outer side in the vehicle width direction, and pressing bushes L6 provided on the inner pressing plate L4 and the outer pressing plate L5.

[0033] The inner pressure plate L4 and the outer pressure plate L5 are formed as identical plate-shaped bodies. The inner pressure plate L4 and the outer pressure plate L5 are provided in the center on the front side in the longitudinal direction of the vehicle body and include a rotation shaft LH that is rotatably supported by the gusset G. The rotation shaft LH has a rotation center in the vehicle width direction, for example. The rotation shaft LH includes, for example, a tubular member LH1 provided on the inner pressure plate L4 and the outer pressure plate L5, and a columnar bushing LH2 press-fitted into the tubular member LH1.

[0034] The tubular member LH1 is welded to the inner pressure plate L4 and the outer pressure plate L5. The bush LH2 is made of an elastic member. A through hole (not shown) is formed in the bush LH2 along the vehicle width direction. A bolt L1 that rotatably supports the link member L with respect to the gusset G is inserted into the through hole. The bush LH2 absorbs the force transmitted from the power unit P to the bolt L1 based on elastic deformation.

[0035] The pressure bushing L6 includes an upper pressure bushing L7 disposed above the rotary shaft portion LH and a lower pressure bushing L8 disposed below the rotary shaft portion LH. The upper pressure bushing L7 and the lower pressure bushing L8 are formed into a cylindrical shape from an elastic member. The upper pressure bushing L7 and the lower pressure bushing L8 absorb the force transmitted from the power unit P to the gusset G by elastic deformation.

[0036] The upper pressing bush L7 abuts against an upper stopper portion G11 (to be described later) provided on the gusset G. The pressing force of the upper pressing bush L7 changes depending on the rotation state of the power unit P. The lower pressing bush L8 abuts against a lower stopper portion G12 (to be described later) provided on the gusset G. The pressing force of the lower pressing bush L8 changes depending on the rotation state of the power unit P.

[0037] The power unit support portion L10 includes a power unit rotating shaft portion L11 that supports the rotation of the power unit P fixed to the inner pressure plate L4 and the outer pressure plate L5, and a rotating shaft support member L12 that supports the power unit rotating shaft portion L11. The power unit rotating shaft portion L11 is formed of a tubular member. A long bolt LB that supports the rotation of the power unit P is inserted into the power unit rotating shaft portion L11.

[0038] With the above-described configuration, the link member L supports the power unit P in rotation based on the rotation axis formed by the bolt L1 and the long bolt LB, and reduces the force transmitted from the power unit P to the body frame F side.

[0039] The gusset G includes, for example, an inner gusset G1 located on the inner side in the vehicle width direction of the body frame F, an outer gusset G2 located on the outer side in the vehicle width direction, and a stopper portion G10 provided between the inner gusset G1 and the outer gusset G2. The pair of inner gusset G1 and outer gusset G2 in the vehicle width direction are provided, for example, on the lower surface side of an inclined portion F1 provided on the body frame F.

[0040] The inclined portion F1 is provided, for example, at a position between the vehicle 1 step 20 and the vehicle seat 10 on the vehicle body frame F. The inclined portion F1 is provided so as to be inclined rearward compared to the vertical direction of the vehicle in a side view. The pair of inner gusset G1 and outer gusset G2 are formed, for example, from plate-like bodies of the same shape. The pair of inner gusset G1 and outer gusset G2 are formed from steel plates. The inner gusset G1 and outer gusset G2 are formed to extend along the inclined portion F1. The inner gusset G1 and outer gusset G2 are welded to the inclined portion F1.

[0041] A support member ST1 that supports the tandem step ST (see FIG. 1) is provided below the outer gusset G2. The support member ST1 is formed of a tubular member with a circular cross section. A circular first through-hole G2H for supporting the support member ST1 is formed below the outer gusset G2. The support member ST1 is, for example, welded to the first through-hole G2H. A second through-hole (not shown) for supporting the rotation shaft of the link member L is formed in the center of the outer gusset G2. A reinforcing plate J is provided around the second through-hole for reinforcement. The reinforcing plate J improves the strength of the area around the second through-hole of the outer gusset G2. A third through-hole (not shown) with the same diameter as the second through-hole is formed in the reinforcing plate J. A bolt L1 that serves as the rotation shaft of the link member L is inserted into the second and third through-holes. As a result, the second through-hole forms a link connection portion L2 that rotatably connects the link members L.

[0042] A reinforcing member G2S extending in the longitudinal direction is provided above the outer surface of the outer gusset G2 in the vehicle width direction. The reinforcing member G2S is formed to improve the strength of the outer gusset G2. Specifically, the reinforcing member G2S is formed, for example, to improve the bending rigidity and shear rigidity of the outer gusset G2. The reinforcing member G2S is formed, for example, by pressing the outer gusset G2 so as to bulge outward in the vehicle width direction. The reinforcing member G2S may be formed by a weld bead, or may be formed by welding a steel rod or a strip-shaped steel plate. The reinforcing member G2S reduces deformation occurring in the outer gusset G2 due to stress transmitted from the stopper portion G10.

[0043] The inner gusset G1 is formed to be plane symmetrical (mirror symmetrical) with the outer gusset G2 in the left-right direction of the vehicle. The inner gusset G1 has the same configuration as the outer gusset G2. By forming the inner gusset G1 and the outer gusset G2 separately, the shapes of the inner gusset G1 and the outer gusset G2 and the position of the stopper portion G10 can be freely set, improving the design freedom of the gusset G.

[0044] A stopper portion G10 is provided between the inner gusset G1 and the outer gusset G2. The stopper portion G10 is a member that abuts against the link member L to restrict the rotation range of the link member L. The stopper portion G10 is provided as a separate part from the inner gusset G1 and the outer gusset G2. Because the gusset G and the stopper portion G10 are provided separately, stress applied to the gusset G can be efficiently dispersed when the link member L abuts against the stopper portion G10 and force is transmitted. Furthermore, because the gusset G and the stopper portion G10 are provided separately, the position and angle of the stopper portion G10 can be easily changed, improving design freedom.

[0045] The stopper portion G10 is composed of an upper stopper portion G11 attached above the link connection portion and a lower stopper portion G12 attached below the link connection portion. The upper stopper portion G11 abuts against the upper pressing bush L7 of the link member L. The lower stopper portion G12 abuts against the lower pressing bush L8 of the link member L.

[0046] The upper stopper portion G11 is formed by bending a steel plate. The upper stopper portion G11 is formed with a rear wall G11A that abuts against the link member L on the rear side in the vehicle longitudinal direction. The rear wall G11A is formed in a rectangular plate-like shape. A pair of side walls G11B is provided in the vehicle width direction at both left and right ends of the rear wall G11A. The pair of side walls G11B are formed in a plate-like shape. The pair of side walls G11B are formed to extend forward in the vehicle longitudinal direction from both left and right ends of the rear wall G11A. The pair of side walls G11B abut against a pair of opposing surfaces of the inner gusset G1 and the outer gusset G2, respectively.

[0047] A leading edge G11C on the front side of the side wall G11B in the vehicle longitudinal direction is fixed to a pair of opposing surfaces of the inner gusset G1 and the outer gusset G2 by fixing means. The fixing means is, for example, welding. As the fixing means, a method other than welding may be used as long as it can fix the gusset G, such as brazing or screwing. The leading edge G11C may be fixed to the inclined portion F1 by fixing means. Because the leading edge G11C is fixed to the gusset G at a position spaced forward of the vehicle from the rear wall, stress acting on the gusset G is more efficiently distributed.

[0048] As shown in FIG. 4, the lower stopper portion G12 is formed by bending a steel plate. The lower stopper portion G12 is formed with a rear wall G12A that abuts against the link member L on the rear side in the vehicle longitudinal direction. The rear wall G12A is formed in a rectangular plate-like shape. A pair of side walls G12B is provided in the vehicle width direction at both left and right ends of the rear wall G12A. The pair of side walls G12B are formed in a plate-like shape. The pair of side walls G12B are formed to extend forward in the vehicle longitudinal direction from both left and right ends of the rear wall G12A. The pair of side walls G12B abut against a pair of opposing surfaces of the inner gusset G1 and the outer gusset G2, respectively.

[0049] A leading edge G12C on the front side of the side wall G12B in the vehicle longitudinal direction is fixed to a pair of opposing surfaces of the inner gusset G1 and the outer gusset G2 by fixing means. The fixing means is, for example, welding. As the fixing means, a method other than welding may be used as long as it can fix the gusset G, such as brazing or screwing. The leading edge G12C may be fixed to the inclined portion F1. Because the leading edge G12C is fixed to the gusset G at a position spaced forward of the vehicle from the rear wall, stress acting on the gusset G is more efficiently distributed.

[0050] In the lower stopper portion G12, a pair of side walls G12B are formed with notches G12E to avoid the support member ST1 (see FIG. 2) of the tandem step ST. The notches G12E are formed at a position radially outward from the outer periphery of the first through hole G2H of the gusset G. The lower stopper portion G12 is provided with a reinforcing wall G12D that connects the pair of side walls G12B together. The reinforcing wall G12D is formed in a rectangular plate shape. The reinforcing wall G12D connects the upper edges of the pair of side walls G11B together.

[0051] If the reinforcing wall G12D and the upper edge of the side wall G11B are not integral, they are fixed to each other by a fixing means such as welding. The provision of the reinforcing wall G12D improves the rigidity of the gusset G and the lower stopper portion G12. The provision of the reinforcing wall G12D improves the rigidity of the region of the gusset G that includes the support portion of the link member L.

[0052] 5, in a side view of the vehicle, the rear wall G11A of the upper stopper portion G11 is disposed at a position that protrudes rearward relative to a rear edge (not shown) on the rear side in the vehicle longitudinal direction of the inner gusset G1 and a rear edge G2K on the rear side in the vehicle longitudinal direction of the outer gusset G2, thereby forming a protrusion G11T. Similarly, in a side view of the vehicle, the rear wall G12A of the lower stopper portion G12 is disposed at a position that protrudes rearward relative to a rear edge (not shown) on the rear side in the vehicle longitudinal direction of the inner gusset G1 and a rear edge G2K on the rear side in the vehicle longitudinal direction of the outer gusset G2, thereby forming a protrusion G12T. The upper stopper portion G11 and the lower stopper portion G12 can be freely disposed relative to the inner gusset G1 and the outer gusset G2, and the protrusion amount and angle of the protrusions G11T and G12T can be arbitrarily adjusted, thereby allowing the gusset G to reliably abut the stopper portion G10 against the link member L.

[0053] The gusset G including the stopper portion G10 described above may be configured as a vehicle part attached to the body frame F of a saddle-ride type vehicle 1. The vehicle part is, for example, a replacement part distributed for repairs. The vehicle part includes the gusset G and the stopper portion G10. The gusset G rotatably supports a link member L that supports a power unit P including a drive source. The stopper portion G10 is provided on the gusset G and abuts against the link member L to restrict the rotation range of the link member L. The stopper portion G10 is provided as a separate part from the gusset.

[0054] As described above, in the vehicle 1 and the vehicle parts, the upper stopper portion G11 and the lower stopper portion G12 are provided as separate parts relative to the inner gusset G1 and the outer gusset G2, and therefore, the stress acting on the inner gusset G1 and the outer gusset G2 that rotatably support the engine can be dispersed, improving the rigidity of the vehicle body and increasing the degree of freedom in design.

[0055] Additionally, within the scope of the present invention, the components in the above-described embodiment may be replaced with known components as appropriate, and the above-described modified examples may be combined as appropriate. For example, the vehicle 1 may be applied not only to motorcycles and three-wheeled motor vehicles, but also to other self-propelled vehicles such as four-wheeled buggies, non-self-propelled vehicles, etc. It may also be applied to vehicles that include an electric motor as a prime mover. The stopper portion G10 may be formed of a solid block. [Explanation of symbols]
