Description

Automobile transmission shaft structure Technical Field The utility model relates to an automobile transmission shaft structure, and belongs to the technical field of transmission shafts. Background The automobile transmission shaft is a key component in an automobile transmission system, and mainly aims to transmit the power of an engine to a driving wheel from a speed changer, simultaneously adapt to the relative motion of all components of a chassis in the running process of the automobile, and when the automobile runs, a shaft lever (especially the chassis transmission shaft) directly faces to the impact of stones, sand grains, metal scraps and the like, and pits or scratches can be formed on the surface of the high-speed splash, so that the shaft lever of the transmission shaft is required to be protected. The utility model discloses a CN222633637U discloses a transmission shaft assembly with good dustproof effect, including the transmission shaft body, the outer wall of transmission shaft body is provided with dustproof mechanism, dustproof mechanism is including rotating the last dust cover of connecting at transmission shaft body outer wall, the bottom sliding connection of going up the dust cover has lower dust cover, the front and the back of going up the dust cover all fixedly connected with connecting sleeve, the outer wall of lower dust cover just fixedly connected with connecting pin in connecting sleeve position department that corresponds, the top of connecting pin just fixedly connected with fixture block in connecting sleeve's top, connecting sleeve's top rotates and is connected with the spacing ring, the logical groove has been seted up to spacing ring's inside, through designing a dustproof effectual transmission shaft assembly, utilizes dustproof mechanism in the device to protect the transmission shaft body, has solved and has dismantled comparatively difficultly after the dust cover on the current transmission shaft assembly damages, and is complex operation. The scheme has the following defects in actual use: When in actual use, as the two ends of the dust cover are not limited, the centrifugal force can cause the upper dust cover and the lower dust cover to displace on the surface of the transmission shaft when the transmission shaft rotates at a high speed, so that the dust cover is not stable enough. Disclosure of Invention In order to solve the technical problems, the utility model provides an automobile transmission shaft structure, which limits upper and lower arc-shaped rubber plates on a transmission shaft, prevents the upper and lower arc-shaped rubber plates from displacing when the transmission shaft rotates, and improves stability. The technical scheme adopted for solving the technical problems is as follows: The automobile transmission shaft structure comprises a shaft body, wherein an upper arc-shaped rubber plate and a lower arc-shaped rubber plate are respectively arranged above and below the shaft body, a limiting assembly for preventing the upper arc-shaped rubber plate and the lower arc-shaped rubber plate from being displaced is arranged on the shaft body, and a locking assembly for fixing the upper arc-shaped rubber plate and the lower arc-shaped rubber plate is arranged on the limiting assembly. Preferably, the limiting assembly comprises two limiting cylinders, the limiting cylinders are respectively arranged at two ends of the shaft body, limiting grooves are formed in inner walls of two sides of the limiting cylinders, upper rubber strips are arranged on two sides of the upper arc-shaped rubber plate, and lower rubber strips are arranged on two sides of the lower arc-shaped rubber plate. Preferably, the locking assembly comprises a first threaded hole, the first threaded hole is formed in the top of the limiting cylinder and is communicated with the limiting groove, a second threaded hole is formed in both ends of the upper rubber strip and the lower rubber strip, and the first threaded hole and the second threaded hole are connected through a long bolt.
