Motor tricycle

Abstract

The invention provides a motor tricycle and belongs to the technical field of vehicles. The motor tricycle comprises a frame, a front suspension structure, a rear suspension structure and an adjustingdevice. The adjusting device is arranged to act on a long rod extending out of the rear suspension structure; an adjusting moving block in the adjusting device moves on the long rod under the actionof a driver, a driving lead screw and a guide rod; a stress arm of force of the long rod is adjusted by changing a distance between an adjusting moving block and the rear suspension structure; when the stress arm is reduced, the limiting strength of the long rod on the rear suspension structure can be enhanced; therefore, the inclination amount of the rear suspension structure is reduced and safety accidents such as rollover are prevented; and when the stress arm is increased, the limiting strength of the long rod on the rear suspension structure can be weakened, so that the inclination amountof the rear suspension structure is increased; the vehicle adapts to road conditions, and the running requirements of the vehicle in a high-speed running state and a low-speed running state are effectively considered, so that the safety guarantee is higher, the service life is longer, and riding is more comfortable.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a three-wheeled motorcycle. Background technique [0002] Because of its low price and good passability, three-wheeled motorcycles have become a relatively mainstream means of transportation and are favored by consumers. [0003] But, at present, the three-wheeled motorcycle on the market is due to the restriction of its structure, and when running at low speed, because the suspension structure of two rear wheels is realized by the shock absorber and the connecting rod connection, when turning or passing through the uneven road surface, there will be Tilting occurs, such as when the speed is low, it will cause serious tilting problems, cause damage to the vehicle structure, and even cause safety accidents such as overturning. Therefore, it is necessary to limit the tilting amount of the rear suspension structure. However, in limiting the tilting amount of the suspension structur...

[0003] But, at present, the three-wheeled motorcycle on the market is due to the restriction of its structure, and when running at low speed, because the suspension structure of two rear wheels is realized by shock absorber and connecting rod connection, when turning or passing the uneven road surface, it will Tilting occurs, such as when the speed is low, it will cause serious tilting problems, cause damage to the vehicle structure, and even cause safety accidents such as overturning. Therefore, it is necessary to limit the tilting amount of the rear suspension structure. However, in limiting the tilting amount of the suspension structure Finally, if the speed of the vehicle is high, it will cause greater vibration when the vehicle is running, which will also damage the structure of the vehicle and affect the riding experience

[0004] In summary, the existing three-wheeled motorcycles have the problem of not being able to take into account the amount of inclination of the vehicle at high speeds and low speeds
