Abstract

PURPOSE: To correspond to weight regulation speedily without going to a measurement place by providing a sensor between each support spring and axle or a sensor between a chassis and the support spring to detect load applied on each support spring and calculating values of various loads by a calculating mechanism. CONSTITUTION: An axel 3 supports a chassis 1 and a load-carrying platform 2 through a support spring 5, and a pressure sensor 6 such as load cell is arranged between the support spring 5 and one axle 3 to output a value of measured load to a calculating mechanism 40 as an electrical signal. By detecting the load (weight of the chassis 1 plus load-carrying platform 2 plus movable load) directly, the calculating mechanism 40 judges whether movable load is proper or not or whether there is a danger of turning over of a vehicle due to one-side movable load or not based on the results of the detection, the weight of the chassis 1 and the load-carrying platform 2 which is stored in advance, or the total weight of the vehicle body when there is no movable load. The calculating mechanism 40 displays the calculated value in a display device 41 and gives an alarm by an alarm unit 42 when the load exceeds the allowance value.

This embodiment also intends to measure the load of the chassis 1 + the bed 2 + the load by the pressure sensor 6, and based on the measurement result, the calculation mechanism determines whether the load is appropriate or not. This is to judge whether or not there is a risk of rollover or the like due to the bias of, and display and warn.

Although a leaf spring is used as the support spring in all of the above embodiments, the present invention is also applicable to a chassis support structure using a spring other than the leaf spring, such as a coil spring, an elastic member such as rubber or resin. It is possible. That is, FIG.

Next, FIG. 9 is a diagram showing an example of a method of calculating the center of gravity of only the vehicle by the calculating mechanism 40 based on the data about the load detected by the load detecting means such as the pressure sensor or the distance sensor. . Here, front and rear axles 3A,
A load detecting means, for example, a pressure sensor N, is provided at both ends of 3B.
o. 1, 2, 3 and 4 are provided, and the position of the center of gravity and weight of only the vehicle are obtained by a total of four pressure sensors. That is, the pressure sensor No. provided on the front axle 3A of the vehicle having no load on the loading platform or the like. Assuming that the load values measured at the measurement points of 1 and 2 are w1 ⁰ and w2 ⁰ , respectively, the pressure sensor Nos.
The apparent weight obtained by combining the loads applied to 1 and 2 is w1 ⁰ + w2 ⁰ , and both loads w1
^0, w2 ⁰ of balanced position each pressure sensor No. 1,2
Is a point P1 on a straight line connecting the two. Since this position P1 is a position where the loads w1 ⁰ and w2 ⁰ are in balance, this position P1
Is the pressure sensor No. at the same time. 1 and No. The distance between two is w2
^{It is} a position to be divided at a ratio of ⁰ : w1 ⁰ .

Similarly, the pressure sensor Nos. 1 and 2 attached to both ends of the rear axle 3B. Respectively w3 ⁰ the measured value by 3 and 4,
if w4 ^0, each pressure sensor No. 3,4 The weight of the apparent obtained by synthesizing the respective took load is w3 ⁰ + w4 ^0, the position where both the load w3 ^0, w4 ⁰ are balanced, each pressure sensor No. It is a point P2 on the straight line connecting the points 3 and 4. This position P2 is the pressure sensor N at the same time.
o. 3 and No. It is a position where the distance between 4 is divided at a ratio of w4 ⁰ : w3 ⁰ .

Therefore, the apparent weight applied to the front axle 3A is
Total of w1⁰ + W2⁰ And the balanced position is P1
And the total apparent weight of the rear axle 3B is w
Three⁰+ W4⁰ Therefore, it is considered that the balanced position is on P2.
Therefore, the load received at the position P1 (w1⁰ + W2⁰ )
W5 for convenience⁰ , Load received at position P2 (w3⁰ + W4

Next, when there is a load on the loading platform or the like, each sensor No. Measured values by 1, 2, 3, 4 are w
1, w2, w3, w4, these measured values w1,
By using w2, w3, and w4, the position of the center of gravity of the entire vehicle including the load can be obtained by the above calculation method. From each measured value w1, w2, w3, w4 when there is a load,
Each measured value w1 ⁰ , w2 ⁰ , w3 when there is no load
^0, w4 ⁰ respectively subtracted value w1-w1 ^0, w2-w
By obtaining the center of gravity by the above calculation method based on the ^{2 0, w3-w3 0,} w4-w4 0, it comes to its center of gravity is the center of gravity of the cargo.

Each measured value w when there is a load
If the center of gravity is obtained by the above method based on 1, w2, w3, and w4, it can be said that the center of gravity is the position of the center of gravity of the entire vehicle including the loaded load.

Therefore, according to the above calculation method, the center of gravity of only the vehicle body, the load, the entire vehicle including the load, and the center of gravity of each of them can be calculated as necessary.

Also, in the case of a vehicle having 6 or more wheels, any 2
The calculation can be performed in the same procedure as above while combining the measured values of the two sensors. In the above-described embodiment, an example in which the invention is mainly applied to a vehicle of a type such as a truck and a trailer that can distinguish a chassis and a cargo bed, but the application of the present invention is not limited to this, but a bus, a passenger car, a wagon, It can be applied to various types of vehicles such as vans. In applying to each type of vehicle, it is necessary to make various design changes corresponding to structural differences according to differences in vehicle types, etc., but the basic load detection structure is one of the aspects of the above embodiment. As far as applicable, any modified structure is included in the present invention.

As described above, in the vehicle of the present invention, the weights such as the total loaded load and the deviation of the loaded load are constantly calculated by the calculation mechanism provided in the vehicle body, and the calculation result is displayed on the display provided in the vehicle body and calculated. Since the alarm is issued when the value exceeds the preset allowable value, it is not necessary to go to the place where the weight measuring device is installed, and regarding the deviation of the total load or the load in any place, whether it is stopped or running. It is possible to know and prevent accidents due to overweight, uneven load, etc.
