A synchronous jacking hydraulic system for armored vehicles with leveling function

Abstract

The invention provides a synchronous jacking hydraulic system with a leveling function of an armored car. The synchronous jacking hydraulic system comprises a sub system I, a sub system II and a biaxial dip angle sensor, wherein the sub system I comprises a first electromagnetic directional valve, a first one-way speed-regulating valve and a first-stage flow distributing and collecting valve; anysub system II comprises a second-stage flow distributing and collecting valve, a first hydraulic lock, a second electromagnetic directional valve, a second one-way speed-regulating valve, a second hydraulic lock, a third electromagnetic directional valve, a first telescopic cylinder and a second telescopic cylinder; the biaxial dip angle sensor is mounted on the armored car; the first telescopic cylinder and the second telescopic cylinder of any sub system II are mounted on the bottom of the armored car; a stretching rod of the first telescopic cylinder and a stretching rod of the second telescopic cylinder are separately connected with the bottom of the armored car. A control system controls a valve group to realize automatic leveling and automatic synchronous jacking of the armored car,so that operations are simple.

Description

technical field [0001] The invention relates to the field of synchronous lifting hydraulic pressure, in particular to an armored vehicle synchronous jacking hydraulic system with a leveling function. Background technique [0002] With the development of our country's military industry, more and more armored vehicles are serving in the army, and the army is becoming stronger and stronger. When armored vehicles are training and fighting in the field, it is more and more common to jack up armored vehicles when they encounter damage to their tracks and wheels. How to quickly and safely jack up armored vehicles, replace tracks, wheels, and repair damaged armored vehicles has become an increasingly important issue. [0003] At present, the common vehicle jacking devices, such as hydraulic jacks for vehicles, often appear to be "powerless" when faced with the large tonnage of armored vehicles. At the same time, when the armored vehicle breaks down, it may be in a low state in a c...

Problems solved by technology

For example, the two vehicle jacking devices invented by the patents with application numbers CN201320180670.7 and CN201610260435.9 can only lift the vehicle at a single point and on one side, and cannot lift the vehicle synchronously as a whole, which may easily cause rollover

A synchronous jacking system invented by the patent application number CN201410298544.0 uses three synchronous motors for jacking, and the cost is relatively high
