Description
Technical field
The utility model relates to a kind of multifunction retractable formula vehicle steering.
Background technology
Bearing circle height and position on present most of automobile are fixed.Its shortcoming is a function singleness, and taken operating seat than large space, not only get on or off the bus and make troubles, and when serious car accident takes place to chaufeur, also can tightly squeeze chaufeur and on the seat, be difficult to escape.The bearing circle that can stretch is also arranged, and as Chinese patent 98214103.3 anticollision bearing circle, but it has only been considered alternative air bag and has not been considered other function.
The utility model content
The purpose of this utility model provides a kind of vehicle steering that has the multifunction retractable formula of kinds of protect function.The difference of it and conventional steering mechanism is: not only have the function of turning to, and have flexible flexible, alarm, function such as automatic train stop when out of control.
Multifunction retractable formula vehicle steering of the present utility model, comprise bearing circle, Steering gear, diversion driving-gear, the middle part along continuous straight runs of described Steering gear is provided with the Steering gear draw-in groove of ring-type, one side of Steering gear draw-in groove is provided with the prominent urceolus of card, the prominent spring of card is installed in the prominent urceolus of card, one end of the prominent spring of card withstands on the bottom of the prominent urceolus of card, the other end withstands on the ball, a small half of prominent urceolus of card release that exposes of ball, its exposed junction withstands in the Steering gear draw-in groove, the bottom of described Steering gear is a castellated shaft, is connected by spline between Steering gear and the described diversion driving-gear, and the axial employing gear wheel locating crotch of diversion driving-gear is spacing, the bottom of Steering gear is connected with piston coaxial line ground in the pressure tank by movable joint, the sidewall at pressure tank middle part is provided with port, and baroswitch has been sent out in the bottom in the pressure tank, and baroswitch is connected with the automobile power source line.
Multifunction retractable formula vehicle steering of the present utility model, wherein said port place is equipped with warning steam whistle.
Multifunction retractable formula vehicle steering of the present utility model, the cross-sectional plane of wherein said gear wheel locating crotch is a channel steel shape, gear wheel locating crotch is fixed on the car body.
Multifunction retractable formula vehicle steering of the present utility model, the cross-sectional plane of the prominent urceolus of wherein said card is an annular arrangement, the prominent urceolus of card is fixed on the car body.
Multifunction retractable formula vehicle steering of the present utility model, wherein said pressure tank is fixed on the car body.
Multifunction retractable formula vehicle steering of the present utility model, when enough axle pressures are applied on the bearing circle, for example chaufeur lies prostrate on the bearing circle, castellated shaft overcomes the elastic resistance of ball and the air resistance in the pressure tank, castellated shaft in driving gear moves axially downwards, bearing circle begins to descend, air is compressed in the pressure tank simultaneously, when bearing circle continues to drop to certain distance, port is closed, and the pressure tank internal gas pressure increases sharply, baroswitch work, the closing automobile general supply, automobile flameout stops.So multifunction retractable formula vehicle steering of the present utility model has following several advantages:
1, during accidental impact, can protect the chaufeur chest to escape injury or alleviate injury.
2, prevent fatigue or lie prostrate on bearing circle after drinking and doze off.
Cross-up causes bigger accident when 3, preventing chaufeur because of acute illness outbreak shock.
4, chaufeur is got on or off the bus more convenient, easier.
Below in conjunction with accompanying drawing multifunction retractable formula vehicle steering of the present utility model is described further.
Description of drawings
Fig. 1 is the front view of the structural representation of multifunction retractable formula vehicle steering of the present utility model.
The specific embodiment
As seen from Figure 1, multifunction retractable formula vehicle steering of the present utility model comprises bearing circle 1, Steering gear 21, diversion driving-gear 9, the middle part along continuous straight runs of Steering gear 21 is provided with the Steering gear draw-in groove 4 of ring-type, one side of Steering gear draw-in groove 4 is provided with the prominent urceolus 5 of card, the prominent spring 2 of card is installed in the prominent urceolus 5 of card, and an end of the prominent spring 2 of card withstands on the bottom of the prominent urceolus 5 of card, and the other end withstands on the ball 3, a small half of prominent urceolus 5 of card release that exposes of ball 3, its exposed junction withstands in the Steering gear draw-in groove 4.The cross-sectional plane of the prominent urceolus 5 of card is an annular arrangement, and the prominent urceolus 5 of card is fixed on the car body 20.The bottom of Steering gear 21 is a castellated shaft 6, be connected by spline between Steering gear 21 and the diversion driving-gear 9, the axial employing gear wheel locating crotch 7 of diversion driving-gear 9 is spacing, and the cross-sectional plane of gear wheel locating crotch 7 is a channel steel shape, and gear wheel locating crotch 7 is fixed on the car body 19.The bottom of Steering gear 21 is connected by movable joint 10 and pressure tank 13 interior piston 12 coaxial line ground, and the sidewall at pressure tank 13 middle parts is provided with port 14, and port 14 places are equipped with warning steam whistle 15.Pressure tank 13 inner bottom parts are provided with baroswitch 16, and baroswitch 16 is connected with automobile power source line 17, by closing of tube internal gas pressure control general supply.Pressure tank 13 is fixed on the car body 18.
When motor turning, bearing circle 1 stressed rotation, castellated shaft drives driving gear 9 and rotates together, and torsion is spread out of fully, reaches the purpose that turns to, and this moment, pressure tank 13 assemblies rotated with castellated shaft 6 because of there being movable joint 10 not connect; When enough axle pressures are applied on the bearing circle 1, for example chaufeur lies prostrate on the bearing circle, castellated shaft 6 overcomes the air resistance in the elastic resistance of ball 3 and the pressure tank 13, moves axially downwards at the middle castellated shaft 6 of driving gear 9, and bearing circle 1 begins decline.Simultaneously, air is compressed in the pressure tank 13, discharges and make warning steam whistle 15 sounding alarms by port 14, reminds chaufeur to note.When bearing circle 1 continued to drop to certain distance, port 14 was closed, and pressure tank 13 internal gas pressures increase sharply, baroswitch 16 work, and the closing automobile general supply, automobile flameout stops.When getting off, chaufeur also can press bearing circle 1, conveniently to get off; When the need cruising, mention bearing circle 1 to normal position and get final product.
The principle of pressure tank 13 is air compression damping principle, and purpose is to make the lifting of bearing circle 1 have flexible preferably.When bearing circle 1 descended, the air pressurized was discharged by port 14 in the pressure tank 13, and the descending speed of bearing circle 1 is restricted.The buffer action of this device can be avoided or alleviate chaufeur chest when contingencies such as generation collision and come to harm.Baroswitch 16 can be common air pressure touch switch, also can be the electronic switch of band baroceptor.But safety value that the utility model is potential and commercial value are that the conventional direction dish is irreplaceable.
In sum, multifunction retractable formula bearing circle can replace the bearing circle of many existing vehicles, is widely used on the petrolic automobile of all kinds of uses.
