Description

[0001] (I) Technical field: The present invention relates to manufacturing a steering device with fully meshed and disengaged internal and external spur gears, which is used for walking machinery and vehicles that travel in a straight line and turn left and right.

[0002] (II) Background technology: Currently, devices that can turn left and right include automobile front axle steering arm devices, motorcycle front wheel steering devices, etc.

[0003] (III) Invention content: The present invention relates to manufacturing a steering device with fully meshed and disengaged internal and external spur gears. The steering device housing has a single-piece bevel gear shaft in the longitudinal direction, power is input from the shaft, a single-piece driven bevel gear is meshed with the bevel gear of the single-piece bevel gear shaft, the driven bevel gear is mounted on the intermediate transmission shaft, the left internal spur gear is mounted on the external spline section at the left end of the intermediate transmission shaft, and the right internal spur gear is mounted on the external spline section at the right end of the intermediate transmission shaft. The left end of the intermediate transmission shaft is provided with a shaft elastic ring to prevent the left internal spur gear from slipping out of the left end of the shaft, and the right end of the intermediate transmission shaft is provided with a shaft elastic ring to prevent the right internal spur gear from slipping out of the right end of the shaft. A needle bearing is installed at the shaft centerline position of the left end of the intermediate transmission shaft. The right end of the left half shaft is installed in the needle bearing, and the right end of the intermediate transmission shaft is installed in the needle bearing. The left end of the right half shaft is installed in the needle bearing. The left shift fork drives the left spur gear to slide to the right on the outer spline section of the left half shaft, so that the left spur gear and the left inner spur gear are fully meshed. The left shift fork drives the left spur gear to slide to the left on the outer spline section of the left half shaft, so that the left spur gear and the left inner spur gear are disengaged. The right shift fork drives the right spur gear to slide to the left on the outer spline section of the right half shaft, so that the right spur gear and the right inner spur gear are fully meshed. The right shift fork shifts the right spur gear to slide rightward on the outer spline section of the right half shaft, so that the right spur gear and the right internal spur gear can be disengaged; when the left spur gear and the left internal spur gear, the right spur gear and the right internal spur gear are in full tooth meshing at the same time, the left and right half shafts can output power at the same time; when the left spur gear and the left internal spur gear are disengaged, while the right spur gear and the right internal spur gear are still in full tooth meshing, the right half shaft outputs power in a single shaft; when the right spur gear and the right internal spur gear are disengaged, while the left spur gear and the left internal spur gear are still in full tooth meshing, the left half shaft outputs power in a single shaft. The number of teeth and module of the left spur gear, the left internal spur gear, the right spur gear and the right internal spur gear are the same.

[0006] (V) Specific implementation methods: Figure 1 As shown, the left shift fork rod (14) is operated to make the left shift fork (13) shift the left spur gear (15) to slide rightward on the outer spline section of the left half shaft (11) until it is fully meshed with the left inner spur gear (12), and the right shift fork rod (10) is operated to make the right shift fork (9) shift the right spur gear (8) to slide leftward on the outer spline section of the right half shaft (5) until it is fully meshed with the right inner spur gear (7). The power is transmitted through the bevel gear shaft (2) and the driven bevel gear shaft (3). The gear (3) and the intermediate transmission shaft (4) transmit power to the left, and the power passes through the left inner spur gear (12), the left spur gear (15), and the left half shaft (11) to realize the leftward output of power; the power transmits power to the right, and the power passes through the right inner spur gear (7), the right spur gear (8), and the right half shaft (5) to realize the rightward output of power. At this time, the power output of the left half shaft (11) and the power output of the right half shaft (5) are realized simultaneously. When the right inner spur gear (7) and the right spur gear (8) are in a full-tooth meshing state, the left shift fork rod (14) is operated to make the left shift fork (13) shift the left spur gear (15) on the outer spline section of the left half shaft (11) to slide to the left until it is disengaged from the left inner spur gear (12), and at this time, the left half shaft (11) will stop outputting power. When the left inner spur gear (12) and the left spur gear (15) are in full tooth meshing state, the right shift fork rod (10) is operated to make the right shift fork (9) shift the right spur gear (8) to slide rightward on the outer spline section of the right half shaft (5) until it is disengaged from the right inner spur gear (7), and the right half shaft (5) will stop power output. The steering device has a compact structure, strong innovation and high practicality. The steering device is easy to manufacture and is arranged on a walking machine or a vehicle to enable the walking machine or the vehicle to travel in a straight line and turn left and right.
