Description
Technical field
The present invention relates to a kind of installation methods of torsion-bar spring in automobile turnover mechanism.
Background technique
It is all the overturning that driver's cabin is realized by torsion-bar spring that domestic middle-size and small-size bogie is most of at present, in order to
Maintenance, torsion-bar spring is the key part in turnover mechanism, generally to ask for help use up may small power overturn driver's cabin,
And it restores to the original state under the action of minimum force.The working principle of turnover mechanism: when driver's cabin is lockup state, i.e. driver's cab turnover
When angle is 0 °, the torsion angle of torsion bar is maximum, and the torque of torsion bar is maximum, and the gravitational moment of driver's cabin is maximum, but torsion bar
Torque is greater than the gravitational moment of driver's cabin；After lockup state releases, since the torque of torsion bar is greater than driver's cabin gravitational moment, in torsion bar
Torque effect under, driver's cabin is turned to forward static after an angle automatically, and cab spoiler α is smaller at this time, torsion bar
Torque it is equal with the gravitational moment of driver's cabin；Artificially when the locking structure position of driver's cabin applies upward relatively low thrust,
Driver's cabin starts to overturn forward, and the energy slow release of torsion bar, the gravitational moment of driver's cabin constantly reduces, and the speed of overturning gradually subtracts
Slowly；When being turned to maximum position, i.e., the center of gravity of driver's cabin is only slight beyond overturning center vertical line, and gravitational moment is almost nil at this time,
Driver's cabin is gently above pushed away with hand at this time, fixes driver's cabin by limiter, the remaining torsion of torsion bar makes limiter be in tension
State.When putting down driver's cabin, driver's cabin utilizes the gravity fall of itself, and gravitational moment is gradually increased, by overturning fore-stock
So that the torsion angle of torsion bar is gradually increased, torque constantly increases for effect to torsion bar, and equally, the increase of torque overcomes gravitational moment,
It is gradually reduced the fall velocity driven, until flip angle α suspends static when smaller, external force slightly, is pulled downward at this time
