Embodiment 1

[0056] A specific embodiment of the present invention discloses a vehicle double-cylinder leveling device based on position control mode, such as figure 1 As shown, it includes a general control unit, left and right electric cylinder extension equipment, and an inclination sensor. The general control unit is respectively connected with the left and right electric cylinder extension equipment and the inclination sensor.

[0057] The general control unit is used to send extension commands to the left and right electric cylinder extension devices of the vehicle during leveling, and to receive the real-time electrical signals fed back by the electric cylinder extension devices and the vehicle tilt angle collected by the inclination sensor during the leveling process. Then control the vehicle twin cylinders for position leveling.

[0058] The left and right electric cylinder extension devices are used to drive the corresponding electric cylinders to perform the extension action ac...

Embodiment 2

[0062] Optimizing on the basis of Embodiment 1, the left and right electric cylinder extension devices are symmetrically arranged on both sides of the vehicle; and, the left and right electric cylinder extension devices each include a motor driver, a leg electric cylinder, and a servo motor, Such as figure 2 shown. The input end of the electrode driver is electrically connected to the output end of the general control unit, and its output end is electrically connected to the input end of the leg electric cylinder. The input end of the servo motor is electrically connected with the output end of the general control unit, and its output end is mechanically connected with the input end of the leg electric cylinder.

[0063] The motor driver is used to drive the electric cylinder of the corresponding leg to perform the stretching action according to the stretching command output by the universal control unit received, and collect the real-time electrical signal of the execution ...

Abstract

The invention relates to a vehicle double-cylinder leveling device based on a position control mode, and belongs to the technical field of vehicle double-cylinder leveling. The problems that in the prior art, the structure is complicated, the response speed is low, the leveling effect is poor, and the environmental suitability is poor are solved. The device comprises a universal control unit, leftand right electric cylinder extending devices and a tilt angle sensor, wherein the universal control unit is used for sending extending instructions to the left and right electric cylinder extendingdevices of a vehicle, and receiving real-time electric signals fed back by the electric cylinder extending devices in the leveling process and a vehicle tilt angle collected by the tilt angle sensor so as to control vehicle double cylinders to conduct position leveling; the left and right electric cylinder extending devices drive corresponding electric cylinders to execute extending action according to the received extending instructions and feed the real-time electric signals containing extending-action executing degree information back to the universal control unit; and the tilt angle sensoris used for collecting the vehicle tilt angle and sending the vehicle tilt angle to the universal control unit. The device has the advantages of being simple in structure, high in practicability, high in response speed, good in leveling effect and the like and can be suitable for any terrain.

Description

technical field [0001] The invention relates to the technical field of vehicle twin-cylinder leveling, in particular to a vehicle twin-cylinder leveling device based on a position control mode. Background technique [0002] Vehicle double-cylinder leveling technology has a wide range of applications in engineering vehicles. [0003] At present, most vehicles use hydraulic cylinder leveling devices for double cylinder leveling. The hydraulic cylinder leveling device generally includes: hydraulic leg cylinder, throttle valve, pressure sensor, inclination sensor, hydraulic oil source, hydraulic pump station, oil source proportional relief valve, valve control combination, and control host computer. By setting a certain valve opening, the hydraulic leg cylinder is stretched out at a certain speed, and the pressure sensor is used to judge whether the leg is on the ground, and the inclination sensor is used to judge whether the vehicle is leveled in the left and right directions....
