In sum, for solving the deficiency in existing juvenile motor vehicle handling maneuver system architecture, need to design a kind of simple in structure, juvenile motor vehicle steering control mechanism of turning to diversification.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of simple in structure, juvenile motor vehicle steering control mechanism of turning to diversification.
The purpose of this utility model can realize by following technical proposal: a kind of juvenile motor vehicle steering control mechanism, comprise gear wheel shaft, panel block, joystick, accessory part, described gear wheel shaft is laterally plugged in panel block and is evenly distributed with some draw-in grooves in the front of gear wheel shaft, described joystick shaft is provided with gear to being plugged in panel block and on joystick, and described gear is evenly distributed with the latch of some settings corresponding to draw-in groove, described latch is provided with the arc surface that active flank and active flank are evagination, between adjacent two latches, with interior concaved circular cambered surface, connect, described accessory part comprises spring and auxiliary block, described auxiliary block is positioned at the reverse side of gear wheel shaft and is stuck on gear wheel shaft side, at auxiliary block middle part, be provided with spring inlay card portion and described spring fitting between spring inlay card portion and panel block.
In above-mentioned a kind of juvenile motor vehicle handling maneuver system, described auxiliary block is shaped as I-shape.
In above-mentioned a kind of juvenile motor vehicle handling maneuver system, described spring inlay card portion is shaped as annular arrangement.
Compared with prior art, the utlity model has following beneficial effect:
1. handling maneuver system is reasonable and simple, has not only reached the function turning to and has saved cost of manufacture simultaneously;
2. the design of accessory part, fits gear and draw-in groove more closely, has improved the service life of steering swivel system.
