Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a steering fork shaft. Background Art
[0002] The connection between the shift fork shaft and the shift fork generally adopts a movable connection. The shift fork is firstly set on the shift fork shaft, and then a pin is used to penetrate into the pin hole connected to the shift fork and the shift fork shaft to fix the shift fork. However, the pin is generally hammered directly into the pin hole with a straight hammer, which is troublesome to install. At the same time, when removing, it is necessary to use a straight hammer to hit the auxiliary cone inserted in the pin hole multiple times, and use the auxiliary cone to hammer the pin in the pin hole from the bottom of the pin hole. The operation is troublesome and it is easy to cause the hammer to deviate and cause injuries to workers. In addition, the pin is easy to fall into the inside of the gearbox, and it is inconvenient to pick up the pin.
[0003] In order to solve the above technical problems, the prior art patent (CN219734200U) discloses a steering fork shaft, including a fork shaft body, a positioning hole, an operating hole, a bevel gear column one, a bevel gear column two, a moving mechanism, a motion transmission mechanism and a spur gear three and other components. The outer side of the rotating shaft one is symmetrically fixedly installed with a bevel gear ring one and a bevel gear ring two, and the outer side of the rotating shaft two is symmetrically fixedly installed with a bevel gear ring three and a bevel gear ring four. By operating with a screwdriver from the outside, the operating shaft rotation transmission is transmitted to the bevel gear column one and the bevel gear column two, so that the bevel gear column one and the bevel gear column two move relatively away from or close to each other, and the fork is quickly fixed or the restriction of the fork on the fork shaft is released. There is no need to use a straight hammer to smash the pin, which is safer. At the same time, the bevel gear column one and the bevel gear column two replace the pin and are integrated with the fork shaft, avoiding the trouble of the pin being hammered into the gearbox below and being difficult to pick up.
