Description

A kind of cargo vehicle cargo bed of anti-rollover

Technical field

The invention belongs to automobile technical fields, and in particular to a kind of cargo vehicle cargo bed of anti-rollover.

Background technique

It is known that sometimes automobile high-speed zig zag is inevitable sometimes in order to hide emergency case, But turning the corner at full speed is avoiding greatly for old driver, especially fully loaded lorry, because its center of gravity is high, weight is big, in high speed racing Road surface is not enough to the support force of unilateral wheel to provide centripetal force high in this way when curved, so will turn on one's side.In news Each tragic incident can be found everywhere.There are also precisely due to cargo loading unevenly, causes lorry cargo bed to roll, when certain journey is arrived in inclination When spending, due to the effect of cargo gravity, so that lorry is turned on one's side.

Summary of the invention

The object of the present invention is to provide a kind of cargo vehicle cargo beds of anti-rollover.It is high to solve previous lorry center of gravity, weight Greatly, cargo bed easily occurs in turning to roll so that lorry is turned on one's side, causes casualties and property loss.

The technical solution adopted is that:

A kind of cargo vehicle cargo bed of anti-rollover, including activity cargo bed and cargo bed pedestal, it is characterised in that:

Activity cargo bed is mounted on the top of cargo bed pedestal, the lower end surface of activity cargo bed and the upper surface of cargo bed pedestal be arc simultaneously And and the two contact matches.Multiple guide ledges are equipped on activity cargo bed bottom surface, on the upper surface of cargo bed pedestal Corresponding position is equipped with multiple guide slides, allows the swing on cargo bed pedestal of activity cargo bed.Multiple guide ledges are embedding Enter in corresponding guide slide, plays to wagon box position-limiting action in the front-back direction.It is equipped in the upper surface of cargo bed pedestal multiple Idler wheel, such cargo bed can in slideway offset slide.The central axis of each idler wheel is arranged in guide slide.At cargo bed bottom The front and back ends of seat are installed with hydraulic pump respectively, are equipped with hinge bar, hinge perpendicular to guide ledges at the lower end center of activity cargo bed The both ends of extension bar are fixed by the connecting rod on the lower end surface of activity cargo bed.It is installed with and holds respectively in the front and back ends of cargo bed pedestal Weight bar, is respectively equipped with the first jack and the second jack between the bearing bar and hinge bar of front and back ends.First jack and Connection ring, the connection ring on the first jack and the second jack piston rod are equipped on the piston rod and shell of second jack It is set on hinge bar and can be freely rotated, the connection ring on the first jack and the second jack shell is respectively sleeved at On the bearing bar of front and back ends and it can be freely rotated.In the shell of first jack and the second jack by pipeline respectively and The liquid outlet of the hydraulic pump at both ends connects.Pressure sensor there are four being set on the lower end surface of cargo bed pedestal, four pressure sensings Detection terminal on device is respectively installed on the position of setting, and the pressure sensor requires to bear immense pressure, and is made With being the load for measuring four-wheel.The signal input terminal of pressure sensor signal output terminal and hydraulic pump passes through conducting wire and peripheral hardware Control system connection.

When work, there are two hydraulic presses, and left and right is respectively regarded as one group by we, and equally four sensors are divided into left and right by we Two groups, the pressure difference of two groups of left and right has induction away from certain value, sensor is arrived, and adjusts hydraulic press and wagon box is measured to sensor The small one side offset of pressure, until cell pressure poor almost nil or wagon box in left and right is displaced to extreme position.

Advantage is: present apparatus structure is simple, improves on existing lorry, improving cost is cheap.Effectively It causes casualties and property loss caused by rollover when avoiding as lorry turning.

Specific embodiment

The cargo vehicle of anti-rollover, the cargo vehicle cargo bed including driver's cabin 1, automobile chassis and anti-rollover.1 He of driver's cabin The cargo vehicle cargo bed of anti-rollover is mounted on automobile chassis.

The cargo vehicle cargo bed of anti-rollover, including activity cargo bed 2 and cargo bed pedestal 4, activity cargo bed 2 are mounted on cargo bed pedestal 4 top, the lower end surface of activity cargo bed 2 and the upper surface of cargo bed pedestal 4 are arc and and the two contact matches.In work Dynamic 2 bottom surface of cargo bed is equipped with multiple guide ledges 5, and multiple lead is equipped on the corresponding position on the upper surface of cargo bed pedestal 4 To slideway 10, allow the swing on cargo bed pedestal 4 of activity cargo bed 2.Multiple guide ledges 5 are embedded in corresponding guiding and slide In road 10, play to wagon box position-limiting action in the front-back direction.Multiple idler wheels 7, such cargo bed are equipped in the upper surface of cargo bed pedestal 4 Can in slideway offset slide.The central axis of each idler wheel 7 is arranged in guide slide 10.In the forward and backward of cargo bed pedestal 4 End is installed with hydraulic pump 12 respectively, is equipped with hinge bar 6, hinge bar perpendicular to guide ledges 5 at the lower end center of activity cargo bed 2 6 both ends are fixed by the connecting rod on the lower end surface of activity cargo bed 2.It is installed with load-bearing respectively in the front and back ends of cargo bed pedestal 4 Bar 11 is respectively equipped with the first jack 8 and the second jack 9 between the bearing bar 11 and hinge bar 6 of front and back ends.1000th Connection ring, 9 piston rod of the first jack 8 and the second jack are equipped on the piston rod and shell of jin top 8 and the second jack 9 On connection ring be set on hinge bar 6 and can be freely rotated, the connection on 9 shell of the first jack 8 and the second jack Ring is respectively sleeved on the bearing bar 11 of front and back ends and can be freely rotated.The shell of first jack 8 and the second jack 9 It is interior to be connected respectively with the liquid outlet of the hydraulic pump 12 at both ends by pipeline.Pressure there are four being set on the lower end surface of cargo bed pedestal 4 Sensor 13, the detection terminal on four pressure sensors 13 are respectively installed on the position of setting, and the pressure sensor is wanted Asking can bear immense pressure, and effect is the load for measuring four-wheel.13 signal output terminal of pressure sensor and hydraulic pump 12 Signal input terminal connected with the CPU on driver's cabin by conducting wire.

Four detection terminals on pressure sensor 13 are respectively provided at the place that bow flat spring 3 is contacted with vehicle bridge.Pressure passes The left and right group of sensor 13 measures pressure and when two groups of gaps is to certain numerical value, hydraulic pump and CPU starting, according to the 1000th Difference between jin top 8 and the second jack 9, adjusts the angle of heel of wagon box.So that the left and right group of pressure sensor 13 is measured Pressure tends to be equal as far as possible.The most ideal situation is that the gravity of cargo bed and normal pressure by force resolution just with turning when Centrifugal force cancels.
