Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, in particular to a three-wheeled motorcycle. Background Art

[0002] Three-wheeled motorcycles have become a more mainstream means of transportation and are favored by consumers due to their low price and good passability.

[0003] However, currently, due to structural limitations, three-wheeled motorcycles on the market will tilt when running at low speeds because the suspension structure of the two rear wheels is connected by shock absorbers and connecting rods, which will cause serious tilting problems when turning or passing through uneven roads. This will cause damage to the vehicle structure and even cause safety accidents such as rollovers. Therefore, it is necessary to limit the inclination of the rear suspension structure. However, after limiting the inclination of the suspension structure, if the vehicle speed is high, it will cause greater vibration when the vehicle is running, which will also damage the vehicle structure and affect the riding experience.

When the force arm of the long rod is shorter, the deformation ability of the long rod is weakened, so that the restraining strength of the long rod on the rear suspension structure is enhanced, thereby reducing the inclination of the rear suspension structure and adapting to the requirements of low-speed operation. When the force arm of the long rod is longer, the deformation ability of the long rod is enhanced, so that the restraining strength of the long rod on the rear suspension structure is weakened, so that the rear suspension structure can be tilted at will according to the road conditions and adapt to the requirements of high-speed operation, so that the inclination of the vehicle in high-speed and low-speed states can be taken into account at the same time, damage to the vehicle structure is avoided, safety is improved, and at the same time, the driving experience is also improved.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 4 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0029] Figure 1 A structural diagram of a three-wheeled motorcycle according to an embodiment of the present invention from one perspective; Figure 2 FIG. 2 is a structural diagram of another perspective of an embodiment of a three-wheeled motorcycle of the present invention. Figure 1 and Figure 2 As shown, the three-wheeled motorcycle provided in this embodiment includes: a frame 1, a front suspension structure 2, a rear suspension structure 3 and an adjusting device 4, the front suspension structure 2 is provided with a front wheel 5, the rear suspension structure 3 is provided with a rear wheel 6, the front suspension structure 2 and the rear suspension structure 3 are respectively provided at two ends of the frame 1, and the adjusting device 4 is provided between the rear suspension structure 3 and the frame 1 and acts on the rear suspension structure 3.

[0030] Specifically, the vehicle frame 1 has a certain length, and the two ends of the vehicle frame 1 are respectively a front end and a rear end, and the front end and the rear end of the vehicle frame 1 provide structural support for the front suspension structure 2 and the rear suspension structure 3 respectively.

[0031] Specifically, the front suspension structure 2 is arranged on the front end of the frame 1, and the front wheel 5 on the front suspension structure 2 is located on the middle axis of the length direction of the frame 1. The front wheel 5 arranged on the front suspension structure 2 provides support for the front end of the frame 1, and the frame 1 can be moved when the front wheel 5 rotates.

[0032] Specifically, the rear suspension structure 3 is arranged on the rear end of the frame 1, and two rear wheels 6 are arranged on the rear suspension structure 3, and the two rear wheels 6 are respectively located on both sides of the length direction of the frame 1, so that the front wheel 5 and the two rear wheels 6 are distributed in an isosceles triangle, thereby improving the stability of the vehicle when supported by three wheels, and ensuring the uniformity of the force on the frame 1, and the structural design is more reasonable. At the same time, the rear suspension structure 3 is provided with a long rod 7 extending horizontally toward one side of the frame 1, so that the rear suspension structure 3 can be connected to other structural components through the long rod 7, providing conditions for the subsequent adjustment of the inclination of the rear suspension structure 3.

[0033] Figure 3 FIG. 1 is a diagram of the coordinated installation of the adjustment device and the rear suspension structure of a three-wheeled motorcycle of the present invention. Figure 1 , Figure 2 as well as Figure 3As shown, the adjusting device 4 is arranged at the rear end of the frame 1 and is located between the frame 1 and the rear suspension structure 3. The adjusting device 4 includes a driver 41, an adjusting screw 42, a guide rod 43 and an adjusting moving block 44. The adjusting screw 42 is parallel to the long rod 7 and is arranged at intervals. At the same time, the guide rod 43 is arranged in parallel on the side of the adjusting screw 42, so that the axial directions of the long rod 7, the adjusting screw 42 and the guide rod 43 are the same, and the driver 41 is arranged on the frame 1 and connected to the adjusting screw 42, so that the driver 41 can drive the adjusting screw 42 to rotate. At this time, when the adjusting screw 42 rotates, the adjusting moving block 44 moves back and forth along the axial direction of the adjusting screw 42 and the guide rod 43 under the joint action of the guide rod 43 and the adjusting screw 42, that is, the adjusting moving block 44 moves back and forth along the arrangement direction of the long rod 7. In addition, one end of the adjusting movable block 44 is screwed onto the adjusting screw rod 42 and sleeved onto the guide rod 43, and the other end of the adjusting movable block 44 is provided with an adjusting hole 441, and one end of the long rod 7 extends into the adjusting hole 441, so that the adjusting movable block 44 can slide on the long rod 7, so that when the adjusting movable block 44 moves back and forth, the length of the long rod 7 between the adjusting movable block 44 and the rear suspension structure 3 can be adjusted, thereby adjusting the force arm of the long rod 7, thereby changing the deformation capacity of the long rod 7, so that the limiting strength of the long rod 7 on the rear suspension structure 3 can change with the movement of the adjusting movable block 44, thereby adapting to the use requirements of different inclination amounts of the rear suspension structure 3 under the two operating conditions of the vehicle at low speed and high speed. At this time, when the vehicle is running at a low speed, the adjusting screw rod 42 is driven to rotate by the driver 41, so that the adjusting movable block 44 moves to a position close to the rear suspension structure 3, that is, the length of the long rod 7 between the adjusting movable block 44 and the rear suspension structure 3 is shorter, thereby making the force arm of the long rod 7 shorter, so that the deformation ability of the long rod 7 is weakened, that is, the limiting strength of the long rod 7 on the rear suspension structure 3 is enhanced, thereby reducing the inclination of the rear suspension structure 3, and the posture is more stable, avoiding serious tilting problems caused by low speed when the vehicle turns or passes through uneven roads, avoiding damage to the vehicle structure, and preventing safety accidents such as rollover. In addition, when the vehicle is running at high speed, the driver 41 drives the adjusting screw rod 42 to rotate in the opposite direction, so that the adjusting movable block 44 moves to a position away from the rear suspension structure 3, that is, the length of the long rod 7 between the adjusting movable block 44 and the rear suspension structure 3 is longer, so that the force arm of the long rod 7 is longer, so that the deformation capacity of the long rod 7 is enhanced, that is, the restricting strength of the long rod 7 on the rear suspension structure 3 is weakened, so that the rear suspension structure 3 can be tilted at will according to the road conditions, so as to adapt to the needs of the vehicle when running at high speed, reduce vibration, avoid structural damage, improve the riding experience, and make the structural design more reasonable.

[0034] More specifically, the long rod 7, one end of which is fixed to the rear suspension structure 3 and used in conjunction with the adjustment device 4, is made of spring steel, and has excellent mechanical properties, anti-elasticity, anti-fatigue performance, hardenability, physical and chemical properties, etc. It is more suitable for use in complex force environments such as restricting the rear suspension structure 3 on the vehicle, and the material selection is more reasonable.

[0035] More specifically, the front suspension structure 2 provided on the front end of the frame 1 includes a front support frame 21 and a front shock absorber 22. One end of the front support frame 21 is hinged to the front end of the frame 1, and the other end of the front support frame 21 extends in a direction away from the frame 1, that is, a front support frame 21 extends in front of the front end of the frame 1, and the extended front support frame 21 can be deflected on the frame 1 to adapt to the undulating road conditions during the travel process. At the same time, a front wheel 5 is provided on the extended end of the front support frame 21, that is, a mounting carrier is provided for the installation of the front wheel 5 through the front support frame 21. At the same time, a raised support plate 11 is provided on the front end of the frame 1, and a front shock absorber 22 is provided between the front support frame 21 and the frame 1, and the two ends of the front shock absorber 22 are respectively hinged to the protruding end of the front support frame 21 and the upper part of the support plate 11, so that when the vehicle passes through an uneven road surface, the front support frame 21 can follow the ups and downs of the front wheel 5, so that the front support frame 21 deflects around the hinge with the frame 1, and the front shock absorber 22 can adapt to the deflection of the front support frame 21 and absorb vibration, which can not only adapt to road conditions and ensure the passability of the vehicle, but also improve the riding comfort, and the structural design is more reasonable.

[0036] More specifically, the front support frame 21 is a double support structure. At this time, the front support frame 21 includes two front support arms 211, which are symmetrical and spaced apart, and the two front support arms 211 are respectively located on both sides of the frame 1, and the two ends of the axle 52 of the front wheel 5 are respectively installed on the two front support arms 211, so that both sides of the front wheel 5 have a structure connected to the frame 1, which not only makes the force on the front wheel 5 and the frame 1 more uniform and the stability higher, but also enables the front wheel 5 to be located on the middle axis of the length direction of the frame 1, thereby improving the vehicle's maneuverability and facilitating the installation and connection of other structural components. In addition, two front shock absorbers 22 can be provided, and one front support arm 211 corresponds to one front shock absorber 22, which further improves the structural strength and shock absorption effect of the vehicle, has a stronger load-bearing capacity, a more comfortable riding experience, and a more reasonable structural design.

[0037] More specifically, the rear suspension structure 3 arranged on the rear end of the frame 1 includes an intermediate support frame 31, a side support frame 32, a rear shock absorber 33, a wheel mounting member 34 and an intermediate connecting member 35. The intermediate support frame 31 is fixed to the rear end of the frame 1, and the extension of the frame 1 at the rear end is achieved through the intermediate support frame 31, which facilitates the installation of other structural components. At the same time, the side support frames 32 are hinged on both sides of the intermediate support frame 31, that is, both sides of the intermediate support frame 31 extend through the corresponding side support frames 32, and each side support frame 32 is hinged on one end away from the hinged intermediate support frame 31, and each wheel mounting member 34 is provided with a rear wheel 6, that is, a rear wheel 6 is respectively provided on both sides of the rear end of the frame 1, so that the two rear wheels 6 and the front wheel 5 are distributed in an isosceles triangle on the frame 1, and the structural stability is higher and the force is more uniform. At the same time, an intermediate connecting piece 35 is hinged on the top of the intermediate support frame 31, and a rear shock absorber 33 is hinged on both sides of the intermediate connecting piece 35, and the two rear shock absorbers 33 are also hinged to one end of the side support frame 32 on the corresponding side where the rear wheel 6 is arranged. At this time, when the vehicle passes through an uneven road surface, the rear wheel 6 drives the corresponding side support frame 32 to deflect around the hinge between the side support frame 32 and the intermediate support frame 31. Through the corresponding rear shock absorber 33, not only the side support frame 32 on the corresponding side is supported, but also energy absorption and shock reduction are achieved. At the same time, when the side support frame 32 deflects with the ups and downs of the rear wheel 6, the intermediate connecting piece 35 can make corresponding deflections under the action of the rear shock absorber 33, so that the vehicle can adapt to the operating environment and the structural design is more reasonable.

[0038] More specifically, the arrangement direction of the hinge axis of the middle connecting member 35 and the middle support frame 31 is perpendicular to the direction of the line connecting the two rear wheels 6, so that the deflection direction of the middle connecting member 35 is consistent with the deflection direction of the side support frame 32, thereby adapting to the movement of the side support frame 32. In addition, one end of the long rod 7 is fixed to the middle connecting member 35, and the direction of the hinge axis of the middle connecting member 35 and the middle support frame 31 is also consistent with the setting direction of the long rod 7, so that the long rod 7 acts on the middle connecting member 35 and limits the deflection of the middle connecting member 35, so as to adjust the deflection size of the middle connecting member 35, thereby controlling the tilt of the rear suspension structure 3. When the adjustment moving block 44 in the adjustment device 4 moves close to the middle connecting member 35, the length of the force arm of the long rod 7 is small, resulting in poor deformation capacity of the long rod 7, thereby limiting the deflection of the middle connecting member 35. , which reduces the inclination of the rear suspension structure 3, adapts to the low-speed operation requirements of the vehicle, and prevents the safety problem of rollover caused by excessive inclination; when the adjustment moving block 44 moves away from the middle connecting piece 35, the length of the force arm of the long rod 7 is longer, resulting in a better deformation ability of the long rod 7, so that the restriction effect of the long rod 7 on the middle connecting piece 35 is smaller, and the middle connecting piece 35 can be greatly deflected under the action of the rear shock absorber 33, thereby increasing the inclination of the rear suspension structure 3, adapting to the high-speed operation requirements of the vehicle, avoiding the problem of excessive vibration during high-speed movement, and improving ride comfort.

[0039] More specifically, two side support frames 32 are provided on each side, and the two side support frames 32 on the same side are respectively an upper support frame 321 and a lower support frame 322, the upper support frame 321 is arranged above the lower support frame 322, and the rear shock absorber 33 on the corresponding side is hinged to the upper support frame 321 or the lower support frame 322, which not only improves the structural strength of the side support frame 32 and the bearing capacity of the rear suspension structure 3, but also enables the upper and lower parts of the wheel mounting member 34 to be hinged by the upper support frame 321 and the lower support frame 322 respectively, thereby preventing the wheel mounting member 34 from deflecting in the vertical plane, improving the stability of the structure, and also making the rear suspension structure 3 more flexible, more adaptable, and more reasonably designed.

[0040] More specifically, a steering device 8 is also provided on the frame 1. The steering device 8 is provided at the front end of the frame 1 and acts on the front wheel 5. That is, the driver can control the deflection of the front wheel 5 through the steering device 8, thereby achieving control of the movement direction of the vehicle, which is more convenient to operate.

[0041] Figure 4 FIG. 1 is a structural diagram of the front wheel of a three-wheeled motorcycle of the present invention. Figure 1 , Figure 2 as well as Figure 4As shown, a steering wheel 51 is sleeved on the wheel axle 52 of the front wheel 5 on the front suspension structure 2, and a steering connecting hole 511 is provided on the steering wheel 51, and one end of the connecting rod of the steering device 8 is hinged on the steering connecting hole 511. At this time, a rotating shaft 521 is vertically provided in the middle of the wheel axle 52 of the front wheel 5, and a rotating shaft hole that can accommodate the rotating shaft 521 is opened in the center of the front wheel 5 along its radial direction, so that after the front wheel 5 is installed on the wheel axle 52, the rotating shaft 521 is located in the rotating shaft hole, and the two sides of the front wheel 5 are fixed by the steering wheel 51, and the two steering wheels 51 clamp the rotating shaft 521 between them, so that the front wheel 5 can be deflected on the wheel axle 52 around the axis of the rotating shaft 521 under the drive of the steering wheel 51, thereby realizing the adjustment of the direction of the front wheel 5.

[0042] More specifically, a seat 9 is also provided on the frame 1. The seat 9 is provided at the rear end of the frame 1 and between the steering device 8 and the adjustment device 4. The frame 1 provides a riding space for the driver and passengers, thereby improving the riding comfort.

[0043] As a preferred embodiment, the upper support frame 321 and the lower support frame 322 are both triangular structures, and the upper support frame 321 and the lower support frame 322 have higher structural strength and more stable structure, thereby providing better support for the rear wheels 6 and improving the carrying capacity of the vehicle.

[0044] The three-wheeled motorcycle provided in this embodiment is provided with an adjustment device 4 between the frame 1 and the rear suspension structure 3, and a protruding long rod 7 is provided on the rear suspension structure 3, an adjustment moving block 44 in the adjustment device 4 is sleeved outside the long rod 7, and the adjustment moving block 44 is driven by the driver 41 in the adjustment device 4 to drive the adjustment screw 42 to rotate, and slides along the guide rod 43 in the adjustment device 4, so that the force arm of the long rod 7 is adjusted by changing the distance between the adjustment moving block 44 and the rear suspension structure 3, and the limiting strength of the long rod 7 on the rear suspension structure 3 is changed. , so that when the vehicle is running at a low speed, the force arm of the long rod 7 can be reduced, so that the restriction strength of the long rod 7 on the rear suspension structure 3 is enhanced, thereby reducing the inclination of the rear suspension structure 3 and preventing the occurrence of safety accidents such as rollover. When the vehicle is running at a high speed, the force arm of the long rod 7 can be increased, so that the restriction strength of the long rod 7 on the rear suspension structure 3 is weakened, thereby increasing the inclination of the rear suspension structure 3, making the vehicle adaptive to road conditions, effectively taking into account the operation requirements of the vehicle in both high-speed and low-speed operating states, with higher safety assurance, longer service life and more comfortable ride.
