The invention discloses a dustproof damping universal joint and steering gear input shaft fastening device. A steering middle shaft is movably connected to the top of a universal joint, an open hole is formed in the lower end of one side of the universal joint, a bolt is arranged at the open hole, two rotation prevention wings are arranged in the middle of the bolt, an anti-off bolt support is arranged at the lower end of the universal joint, one end of a steering gear input shaft is movably connected with the bottom end of the universal joint, an inner lubrication oil conveying pipe is arranged in one side of a protection jacket, and a fixed connection part is arranged at an oil inlet of the inner lubrication oil conveying pipe. According to the dustproof damping universal joint and steering gear input shaft fastening device, the open hole is arranged at the installation position of the universal joint, so that the installation of the bolt is facilitated; the two rotation prevention wings arranged in the middle of the bolt can prevent the bolt from rotating and failing in installing when the bolt is assembled and disassembled; the anti-off bolt support at the lower end of the universal joint has a limit function and can prevent the bolt from falling when a nut is assembled; the installation structure is fastened to the lower end of the universal joint through the bolt and the nut.
Description
Technical field [0001] The invention relates to a fastening device, in particular to a dust-proof and shock-absorbing universal joint and a steering gear input shaft fastening device, which belongs to the technical field of auto parts. Background technique [0002] There are generally two ways to fasten the universal joint and steering gear input shaft: [0003] 1. Tap the threaded holes directly on the universal joint. This installation method can prevent the bolts from falling off when installing the bolts. However, the installation space here is narrow and it is not easy to install and tighten, and if the lower end of the universal joint is damaged during the later replacement, the lower end of the universal joint will be damaged. Forcing the replacement of the entire steering intermediate shaft, which causes unnecessary waste. [0004] 2. Make a smooth hole at the installation place of the universal joint, and use a bolt to pass through the smooth hole and then fasten it with a ...
