Abstract
The utility model discloses an on-board loading limitation device comprising a pressure sensor, a weighting meter and a controller. The pressure sensor is arranged between each vehicle bearing steel board spring and the vehicle axle; the weighting meter is arranged on the instrument plate in the vehicle cab; the pressure sensor is connected with the weighting meter by a signal transition line; the weighting meter is connected with the controller by the signal transmission line; the controller controls the cutting or being through of the vehicle power; the weighting meter receives the pressure data signal from the pressure sensor and displays the loading weight of the vehicle; and when the loading weight of the vehicle exceeds the limitation, the controller will automatically cut the live wire of the vehicle power according to the data signal from the weighting meter to stop power supply and fail the vehicle operation, thus the purpose of load limitation is achieved.
Description
Technical field
The utility model relates to a kind of control setup, particularly a kind of automobile-used load limitation device.
Background technology
At present, because ordering about of interests, the automobile overrun and overload is very general, traffic management system is administered also very difficult, the automobile overrun and overload, its tire, driving engine, steering swivel system are loaded excessive, very easily cause blowing out, the generation of situation such as off-axis, rollover, braking direction are malfunctioning, cause the pernicious traffic accident of car crash, according to statistics, overloading wagon transfinites, and transporting causes trouble accounts for more than 30% of traffic accident sum, accounts for more than 55% of lorry accident, cause economic loss to reach more than 50%, and the personal casualty that passenger carriage overloading caused is startling especially; The accident vehicle of serious overload also allows existing standard breakdown lorry powerless, present accident emergency rescuing system is become can't bear the heavy load.In addition, because the load of overrun and overload vehicle is considerably beyond the design and the ability to bear of highway and bridge, cause highway pavement to occur serious rut prematurely, gather around bag, cheat problems such as groove, frost boiling and be full of cracks, even cause the avalanche of highway, bridge, culvert, shortened the service life of road, bridge greatly, caused highway just to occur the phenomenon of damaging in advance in less than the time of half at design life.
The utility model content
The purpose of this utility model be for solve that above-mentioned vehicle overload overload phenomenon is difficult for administering and this phenomenon to highway, bridge collapse, easily the problem of traffic accident takes place, and provide a kind of automobile-used load limitation device.
The utility model includes pressure sensor, weighing instrument, controller, wherein, pressure sensor is located between each automobile load-bearing steel spring and the vehicle bridge, weighing instrument is located on the gauge panel of automobile cab, pressure sensor is connected with weighing instrument with signal transmssion line, weighing instrument is connected with controller with signal transmssion line, and the live wire of controller Control of Automobile power supply is disconnected and logical, and weighing instrument receives the pressure data signal of pressure sensor and the load carrying ability of display automobile.
The utility model converts the load carrying ability of automobile to data-signal by pressure sensor, this data is given weighing instrument, show by the form of weighing instrument with numeral or pointer, make things convenient for driver or searcher to understand the load carrying ability of this car, when the load carrying ability of automobile surpasses the limit for tonnage amount, the data-signal that controller transmits according to weighing instrument, automatically cut off the live wire of automobile power source, stop electric power supply, automobile can not be started travel, thereby reach the purpose of limit for tonnage.
Description of drawings
Fig. 1 is a parts connection diagram of the present utility model.
Fig. 2 is the installation site scheme drawing of pressure sensor of the present utility model on automobile.
Fig. 3 is the distribution schematic diagram of pressure sensor of the present utility model on automobile.
The specific embodiment
See also Fig. 1, shown in Figure 2, the utility model includes pressure sensor 1, weighing instrument 2, controller 4, wherein, pressure sensor 1 is located between automobile load-bearing steel spring 6 and the vehicle bridge 7, weighing instrument 2 is located on the gauge panel of automobile cab, pressure sensor 1 usefulness signal transmssion line 3 is connected with weighing instrument 2, weighing instrument 2 usefulness signal transmssion lines 3 are connected with controller 4, the live wire 5 of controller 4 Control of Automobile power supplys is disconnected and logical, and weighing instrument 2 receives the pressure data signal of pressure sensor 1 and the load carrying ability of display automobile.
Please consult shown in Figure 3ly again, all be provided with pressure sensor 1 between each automobile load-bearing steel spring 6 and the vehicle bridge 7.
The utility model converts the load carrying ability of automobile to data-signal by pressure sensor 1, this data is given weighing instrument 2, show by the form of weighing instrument 2 with numeral or pointer, make things convenient for driver or searcher to understand the load carrying ability of this car, when the load carrying ability of automobile surpasses the limit for tonnage amount, the data-signal that controller 4 transmits according to weighing instrument 2, automatically cut off the live wire 5 of automobile power source, stop electric power supply, automobile can not be started travel, thereby reach the purpose of limit for tonnage.
Claims (2)
