example 1

[0026] Example 1: see figure 1 , figure 2 and image 3 , a self-weighing system for a leaf spring suspension vehicle, including a displacement sensor and a mounting bracket, an electronic control unit (ECU), a display screen, a calibration knob and a connecting wire harness. Its installation form is: in the front suspension, such as figure 1 As shown, the displacement sensor 4 is installed between the displacement sensor upper bracket 5 and the leaf spring pressure plate 6, and the displacement sensors 4 are respectively hinged thereto. When the weight of the vehicle changes during the loading process, the leaf spring deforms under the load, and the middle part of the leaf spring will move up relative to the frame, and the deformation of the leaf spring can be obtained through the displacement sensor; in the rear balance suspension, such as figure 2 As shown, the upper end of the displacement sensor 4 (the main part of the displacement sensor) is hinged with the upper bra...

example 2

[0028] Example 2: see figure 1 , figure 2 and Figure 4 . figure 1 and figure 2 The layout is similar to Example 1. Figure 4 It can be seen that there are 4 displacement sensors 4 in total, of which there are two on the front axle, two on the balance suspension of the rear axle, and image 3 Compared with the front axle, there is one more front axle. This is because the vehicle with the drive form 8×4 has two front axles and leaf spring suspension structures. Vehicles, figure 1 The structure shown has two sets, arranged front and back on the vehicle frame assembly 2, figure 2 The structure shown has a set, consistent with a drive form 6×4 vehicle. so Figure 4 There are 4 displacement sensors in total. When the system is working, the ECU needs to receive the signals of these four displacement sensors and perform digital-to-analog conversion. At this time, the calibration of the system needs to flash in the program corresponding to the drive type 8×4 in advance, a...

Abstract

Disclosed is a plate spring suspension vehicle self-weighing system. The plate spring suspension vehicle self-weighing system comprises displacement sensors (4), an electronic control unit and a display screen which are connected through wires. For a single-shaft plate spring suspension, the displacement sensors (4) are arranged on a plate spring pressing plate (6) in the middle of a vehicle axle; for a balanced suspension, the displacement sensors (4) are distributed at both ends of a single-side plate spring; the electronic control unit process signals transmitted by the displacement sensors (4) to calculate the total weight of the whole vehicle. The plate spring suspension vehicle self-weighing system can display the total weight of the whole vehicle in real time according to the loading status of the vehicle, and the weight measured in real time is displayed on the display screen to facilitate observation of a driver at any time.

Description

technical field [0001] The invention relates to the technical field of automobile machinery and electronics, in particular to a self-weighing system for a leaf spring suspension vehicle. Background technique [0002] With the intensified efforts to control over-exceedings and the increasingly standardized operation of the logistics market, standard-load transportation has gradually become the mainstream. Vehicle users need to load more goods without overloading to ensure their own income. This requires weighing the loaded vehicle. If it is overloaded, it is necessary to unload the excess goods. If it does not reach the rated load, it can load more goods. . Such repeated loading and unloading of goods and weighing reduces transportation efficiency and increases the cost of loading and weighing. [0003] In view of the above-mentioned vehicle full-load weighing requirements, it is necessary to develop a vehicle self-weighing system to ensure that users can monitor the total ...
