Description
Technical field
The utility model relates to vehicle safety fender guard field, is specifically related to a kind of vehicle's center of gravity control apparatus.
Background technology
At present due to the development of auto-industry, no matter be that country and the individual quantity having automobile and other vehicle constantly increase.Due to path problem, make automobile and the skew of other vehicle's center of gravity, cause vehicle damping spring stress irregular and the traffic accident that causes gets more and more.
The prior art patent No.: CN2292701Y gravity type balancing device for vehicle, be made up of oil cylinder (1) and oil cylinder (2), piston (3) and piston (4) are placed in oil cylinder (1) and oil cylinder (2) respectively, the piston rod (31) of piston (3) lower end and the piston rod (41) of piston (4) lower end, all through diapire under oil cylinder (1) and oil cylinder (2), oil cylinder (1) sidewall is upper and lower is respectively shaped with a hydraulic fluid port (11), (12); Oil cylinder (2) one sidewall is upper and lower is also respectively shaped with a hydraulic fluid port (21), (22), connected pipes (5) one end is connected with the upper hydraulic fluid port (11) of oil cylinder (1), the other end is connected with the lower hydraulic fluid port (22) of oil cylinder (2): connected pipes (6) one end is connected with the lower hydraulic fluid port (12) of oil cylinder (1), the other end is connected with the upper hydraulic fluid port (21) of oil cylinder (2), junction all adopts oil pipe coupling nut (7) to lock, and in oil cylinder (1), (2) and connected pipes (5), (6), hydraulic oil (8) is all housed.
The ingenious utilization employing of prior art two piston-type hydro compressing cylinders, pass through Opposite direction connection with two oil pipes, and piston are moved up and down, keep balance between two forces between two oil cylinders.Be loaded between the vehicle body of vehicle and axletree, vehicle's center of gravity deviation angle can be kept to reduce, keep vehicle operating steady.But the reaction of this kind of structure is slow, when automobile low-speed travels, this structure can use.For the vehicle of fast running, prior art is inapplicable, because vehicle is when fast running, centre-of gravity shift occurs instantaneously, and it is too slow that prior art utilizes the flowing of cylinder body inner fluid to reach the reaction of adjustment vehicle's center of gravity.
Now be badly in need of a kind of vehicle's center of gravity control apparatus that can respond vehicle's center of gravity skew fast as can be seen here.
Utility model content
The purpose of this utility model is to provide a kind of vehicle's center of gravity control apparatus that can respond vehicle's center of gravity skew fast.
For achieving the above object, the technical solution of the utility model is as follows:
The base case that this programme provides is: vehicle's center of gravity control apparatus, comprises pivot shaft, and described pivot shaft is provided with vertical rod, and this vertical rod is provided with cross bar, and described vertical rod and cross bar removably connect, described cross bar be provided with block away from vertical rod end; Described cross bar is arranged with slide block; Described vertical rod is provided with displacement pickup for detecting slider displacement and controller, and controller is electrically connected with displacement pickup; The two ends of described pivot shaft are also provided with two high-pressure gasbags respectively, described two high-pressure gasbags are equipped with the electric control valve along pivot shaft axial direction, and the direction of two electric control valves is contrary, and this electric control valve is electrically connected with controller.
In this programme vehicle's center of gravity control apparatus, pivot shaft is used for the effect of supported rod erecting and high-pressure gasbag.Vertical rod plays support rail, displacement pickup and controller.The information of controller to displacement pickup transmission judges, and selects the Push And Release of the electric control valve controlling high-pressure gasbag.Axial arranged along pivot shaft of the direction of electric control valve is when facilitating electric control valve to open, and the air-flow produced during gas ejection in high-pressure gasbag is along the axial direction of pivot shaft, and then the reaction thrust that air-flow is produced is along the axial direction of pivot shaft.The direction of two electric control valves is contrary, and the electric control valve according to the set direction which direction of vehicle's center of gravity skew is opened.This device determines by the direction that slide block offsets the direction that vehicle's center of gravity offsets.
Principle of work and the advantage of this programme are: when vehicle travels in reason, if vehicle's center of gravity skew is less, then electric control valve is not opened.When vehicle is in negotiation of bends or sudden stop, when there is larger transient deflections in vehicle's center of gravity, slide block is larger near the distance of (or away from) displacement pickup, now displacement pickup by information feed back in controller, controller according to the direction of slide block movement (near or away from displacement pickup), the electric control valve contrary with vehicle's center of gravity offset direction is selected to open, now high-pressure gasbag abrupt release goes out powerful high pressure draft, and then give vehicle antagonistic force, avoid vehicle, because centre-of gravity shift is excessive, the accidents such as vehicle rollover occur.
Preferred version one: based on the preferred version of scheme, described vertical rod is also provided with limited post, and this limited post avoids slide block in sliding process, and when slide block moves to vertical rod direction, slide block breaks displacement pickup.
Preferred version two: based on the preferred version of scheme or preferred version one: described block is connected on pivot shaft, and now cross bar has two strong points, adds the stability of cross bar, cross bar is converted to simple beam structure from cantilever beam structure.
Preferred version three: the preferably preferred version of two: pivot shaft two ends are separately installed with butt flange, butt flange facilitates pivot shaft to be connected with the vehicle frame of vehicle.
Preferred version four: based on the preferred version of scheme or preferred version three: the shape of cross section of described cross bar is polygon, can overcome slide block when sliding on horizontal, slide block generation rotation by actv..
Preferred version five: the preferably preferred version of: the shape of cross section of described pivot shaft is square, vertical rod and cross bar are all positioned at top during pivot shaft horizontal arrangement, high-pressure gasbag is positioned at bottom during pivot shaft horizontal arrangement, and the electric control valve on described two high-pressure gasbags is arranged in opposite directions; The shape of cross section of vertical rod is oblong, and the cross-sectional plane of described limited post is circular, and the length of limited post is 2 times of displacement pickup length, and described slide block is cylinder.
The advantage of this programme: the shape of cross section of strut bar is square, facilitate vertical rod, high-pressure gasbag fixing, if the cross-sectional plane of strut bar be circle, then fix vertical rod, baffle plate and high-pressure gasbag time more difficult.Electric control valve on two high-pressure gasbags is arranged in opposite directions, when high-pressure gasbag inject high pressure gas, jet-impingement can be avoided on the tire of vehicle, affect the stability of vehicle.
