The alarm module converts and extracts signals transmitted by the induction module to form clear digital information; and meanwhile, a rated load alarm function is set, and when the digital information output value is detected to reach 95% of the standard load value of the truck, the sound-light alarm instrument gives an alarm to remind a driver of approaching the rated load.
The limiting module is connected with the vehicle starting loop and controls the starting and stopping of the vehicle; once the truck cannot be started to get on the road due to overload, the truck needs to be unloaded to a rated load and then can be started.
Furthermore, the induction module is selected as a strain gauge which is arranged on the steel plate spring group.
Furthermore, a group of strain gauges are respectively arranged on the left side and the right side of the automobile.
Furthermore, the alarm module comprises two groups of input signal ports, an output port and an audible and visual alarm; each group of strain gauges is respectively connected into a group of signal ports; the output port is connected with the limiting module.
The alarm module is simultaneously provided with an unbalance loading reminding function, when the error of the measured values of the left and right strain gauges is overlarge, an alarm is given, if the error of the left and right data is more than 10%, the system alarm gives an alarm to remind a driver of checking the unbalance loading state.
Furthermore, the limiting module is a relay, an input loop of the relay is connected with the alarm module, an output loop of the relay is connected with the automobile starting loop, and the relay is opened or closed according to the value of the output quantity of the alarm module.
An output point is arranged on the sensor and is connected to a truck starting loop. When the load exceeds the rated load or the error of the measured values of the left and right groups of strain gauges is overlarge, the truck starting loop is cut off through the relay.
The utility model has the following beneficial effects:
(1) the current freight tonnage is dynamically told to the driver in the loading process of the truck, and the unbalanced loading and overload states of the driver are reminded.
(2) The device is connected to a truck starting loop, and once the truck cannot be started to get on the road due to overload, the truck can be started only after being unloaded to a rated load.
(3) The vehicle is stopped to display the load, so that each high-speed entrance can directly judge whether the vehicle is overloaded or not.
(4) The system is convenient for the road administration department to randomly patrol and enforce law, and can judge without driving to the place with the wagon balance.

Wherein: 1. a sensing module; 2. an alarm module; 3. a restriction module; 4. starting a loop; 5. a strain gauge; 6. an audible and visual alarm; 7. a relay.
Detailed Description
The utility model is further described with reference to the following figures and detailed description.
As shown in fig. 1, an overload limiter for an automobile includes a sensing module 1, an alarm module 2 and a limiting module 3, wherein the sensing module 1 is connected with the alarm module 2, and the alarm module 2 is connected with the limiting module 3.
As shown in fig. 2, the sensing module 1 is arranged at the bottom of the carriage and is used for sensing the vehicle-mounted weight; the induction module 1 can be specifically selected as a strain gauge 5; taking a common truck with left and right leaf spring suspensions as an example, the heavy truck suspensions generally employ a leaf spring structure. The steel plate spring is arranged between the frame and the axle and mainly used for bearing, damping and buffering. All loads of the truck are transmitted to the axle through the leaf springs, and the leaf springs deform along with the increase of the loads. Therefore, considering the unbalanced load state, the overall structure and the stress state of the truck, the strain gauges 5 are respectively arranged between the uppermost steel plate springs of the left and right steel plate spring groups, and the two bridge groups are used for load measurement.
As shown in fig. 2, the strain gauge 5 is connected with the alarm module 2 through a circuit; the strain gauge 5 is connected into the circuit of the alarm module 2 in a bridge circuit mode; each strain gauge 5 corresponds to a bridge circuit.
The alarm module 2 is provided with ports of power supply, input signal, output and the like, and is also provided with an audible and visual alarm 6. The steel plate springs on the two sides deform under the action of load, signals of the strain gauges 5 are respectively input into the alarm module 2, and signal data are processed by the alarm module 2 to detect the load capacity of the truck.
The alarm module 2 has a function of detecting an unbalance load: the alarm module 2 adopts double channels and is respectively connected with the two strain gauges 5, the left side and the right side are respectively provided with load data input, if the error of the load data on the left side and the right side is more than 10%, the audible and visual alarm 6 gives an alarm to remind a driver to check the unbalance loading state.
The alarm module 2 converts and extracts the signals transmitted by the induction module 1 to form clear digital information.
The alarm module 2 has the function of detecting overload: when the truck is loaded, if the load exceeds 95% of the rated load, the audible and visual alarm 6 in the alarm module 2 gives an alarm to remind a driver of being overloaded. Meanwhile, the alarm module 2 is externally connected with a digital display device to display the measured values at two sides in real time. The digital display device is arranged in front of or behind the truck and is easy to observe.
As shown in fig. 2, the limiting module 3 is connected to the alarm module 2, and the limiting module 3 is connected to a start circuit 4 of the vehicle, so as to control the start/stop state of the vehicle.
The limiting module 3 can be selected as a relay 7, an input loop of the relay 7 is connected with the alarm module 2, an output loop of the relay 7 is connected with the automobile starting loop 4, and the relay 7 is opened or closed according to the value of the output quantity of the alarm module 2; when the vehicle is overloaded or unbalanced loaded, the vehicle starting circuit 4 is disconnected.
The above is the preferred embodiment of the present invention, and several other simple substitutions and modifications made on the premise of the inventive concept should be considered as falling into the protection scope of the present invention.
