Description
Technical field
The invention belongs to delivery vehicle maintenance technique field, in particular to the boss bolt pretightning force of HWIL simulation controls
Training system.
Background technique
Wheel hub is the important composition unit of the delivery vehicles ground-engaging element such as aircraft, vehicle, under some conditions, suffered by wheel hub
External impact force variation is violent, the safety in operation of boss bolt nut tightened precision and be directly related to delivery vehicle, wheel hub
The too large or too small operation to delivery vehicle of the pretightning force of bolt and nut is all great security risk, when pretightning force is too small,
Bolt and nut is easy to produce loosening, and the frictional force between component conjunction plane reduces, and bolt load increases, and will cause under extreme case
Bolt fracture and nut fall off and accident occur, if pretightning force is excessive, Yi Yinqi screw thread, which generates, to be plastically deformed and then may lead
The fracture for causing bolt may result in nut bolt connection failure, fatigue wear.Therefore, in wheel hub installation process, accurately
The pretightning force of control wheel hub bolt and nut is very important.
For at present, the method for widely applied control wheel hub bolt and nut pretightning force is by screwing force in practice
The moment method of square directly controlled, moment method can more conveniently control the pretightning force of boss bolt nut, generally pass through torque
The torque value that spanner is shown controls the pretightning force of connected piece, and this operation is easy to operate, intuitive, however, in specific ring
Under border and situation, for example, in operational environment, the field disaster relief and need do not having under the situations such as quick-replaceable delivery vehicle wheel hub
When capable of showing that the torque wrench of torque value or replacement environment are not allowed using torque wrench, often there is boss bolt spiral shell
Excessively high or too low situation is arranged in female pretightning force, brings great security risk to the operation of delivery vehicle.
In conclusion to achieve the purpose that reliably to install, replace delivery vehicle wheel hub, it just must be right in training usually
The control gimmick of pretightning force is practiced, and maintenance support personnel pass through the prolonged practice for controlling pretightning force gimmick repeatedly,
Muscle is allowed to form a kind of memory, to achieve the purpose that no show tools can equally reach default pretightning force, this technical ability exists
Battlefield, field disaster relief and rescue fast and reliable repairing when it is especially important, therefore there is an urgent need to it is a kind of for maintenance personal practice can
Equipment and the training method of gimmick are controlled depending on efficient boss bolt nut pretightning force to improve current predicament.
Summary of the invention
The present invention provides a kind of boss bolt pretightning force controlled training system of HWIL simulation, and the present invention will change currently
