Abstract

The invention relates to the automatic turning-prevention device of the motor vehicles, which comprises the incline signal device, the electromagnetic hydraulic direction valve, the hydraulic oil tank, the supporting body and hand control valve. The supporting body maintains the contracting state as the vehicle runs smoothly. When the moment of inclining and turning over, the vehicle protrudes the supporting body quickly and automatically to the ground and enlarges the supporting area and prevents the turning over. When the vehicle returns to smooth running, it uses the hand operational valve to take back the supporting body; it also can use the hand operational valve to protrude the supporting body in advance to prevent the turning over. The invention is suitable for all kinds of motor vehicles and especially for the motor tricycle.

Description

Power actuated vehicle prevents tipping unit automatically

The present invention relates to a kind of power actuated vehicle and prevent tipping unit (calling " anti-tipping unit " in the following text) automatically.The power actuated vehicle tipping is a kind of people of causing, wealth injures and deaths heavy losses and the accident that is difficult to take precautions against.Particularly three wheeled motor car is a kind of extremely unsettled transportation means.The fast development of the agricultural three-wheeled motor vehicle of China is in recent years risen traffic accident rate greatly, and brings bigger hidden danger.

That the present invention has designed is a kind of " anti-tipping unit ", and it can give the tipping of preventing motor-vehicle automatically.

The object of the present invention is achieved like this: " anti-tipping unit " is made up of tilt signals device, electromagnetic hydraulic pressure change-over valve, hydraulic ram (the piston upper end of hydraulic ram is equipped with spring), supporter, manually operated valve, oil pump, fuel tank etc.It makes liquid produce the rule on plane, Hengshui forever with " the earth's core " to the gravitation of liquid, is applied on " anti-tipping unit ".During the vehicle smooth-ride, supporter is contraction state.When the inclination of vehicle angle reaches a certain angle that is about to tipping (is the tipping critical angle, call critical angle in the following text) before the time, the tilt signals device sends signal immediately, the electromagnetic hydraulic pressure change-over valve is connected oil and the fuel tank in the hydraulic ram, spring in the hydraulic ram ejects piston rapidly, and the supporter on the piston is stretched out, and support body supports is to ground, enlarge vehicle support surface long-pending (promptly having enlarged critical angle), prevented the tipping of vehicle; When vehicle recovers smooth-ride, can utilize manually operated valve to regain supporter, to keep the original crossing ability of vehicle; Can also utilize manually operated valve as required, supporter is stretched out, prevent tipping in advance.The tilt signals device sends the angle of inclination of signal, can adjust the level of conducting liquid and adjust, to adapt to different vehicle, the different needs of vehicle's center of gravity height by trimming screw.

Below, (is example with the three wheeled motor car) describes " anti-tipping unit " principle of work in detail in conjunction with the accompanying drawings: by Fig. 1, " anti-tipping unit " is made up of tilt signals device (1), electromagnetic hydraulic pressure change-over valve (2) hydraulic ram (3), supporter (4), manually operated valve (5) etc.By Fig. 4, hydraulic efficiency pressure system is made up of oil pump (6), safety valve (7), fuel tank (8), spring (9) etc.By Fig. 5), tilt signals device (1) is made up of housing (10), conducting liquid (11), trimming screw (12) etc.

By Fig. 1,2,3 as can be known, vehicle does not have when tilting to travel, and the line of gravity of vehicle's center of gravity G is in the bearing surface that three fulcrums A, B, M are determined, vehicle can tipping.Housing (10) and conducting liquid (11) in the tilt signals device (1) are the level of state, and "+" at its two ends, "-" electrode are off-state, and tilt signals device no signal is sent, and supporter is contraction state.When inclination of vehicle (is example to be tilted to the left), by Fig. 2,3 as can be known, critical angle this moment is 12 °, center of gravity G moves to G ' time vehicle will tipping, before this in a flash, by Fig. 5, the conduction in the tilt signals device (1) is tucked in body (11), flow to the left end of housing (10) owing to the inclination of housing (10), connect the power supply "+" of left end, "-" utmost point sends electric signal, by Fig. 4, electromagnetic hydraulic pressure change-over valve (2) is connected oil and the fuel tank (8) in the hydraulic ram (3), spring (9) ejects piston rapidly, and the supporter (4) on the piston is stretched out, and supporter (4) supports to ground, by Fig. 3, increased a fulcrum (M '), having enlarged vehicle support surface, long-pending (promptly enlarged critical angle, the critical angle of this moment is 18 °, center of gravity is G "), has prevented the tipping of vehicle; When vehicle recovers smooth-ride, by Fig. 4, can utilize manually operated valve (5) to regain supporter (4), to keep the original crossing ability of vehicle; Can also utilize manually operated valve (5) as required, supporter (4) is stretched out, prevent tipping in advance.By Fig. 5, be processed with inclined-plane (α) on the housing (10), in the time of can preventing that vehicle from jolting, conducting liquid (11) mistaking signal that splashes.The angle of inclination that tilt signals device (1) sends signal can be adjusted the level of conducting liquid (11) and adjust, to adapt to different vehicle, the different needs of vehicle's center of gravity height by trimming screw (12).Above-mentioned explanation is to be example with the motor tricycle.In like manner, four-wheel motor vehicles also can be equipped with " anti-tipping unit ".

Compare this device with modern technologies and have following advantage:

1, this rule of plane, Hengshui is theoretical foundation to utilize " the earth's core " gravitation to make liquid produce forever, and is namely advanced Again reliable.

2, simple in structure, manufacturing, installation, easy to adjust.

3, cost is low, is convenient to promote.
