Abstract
A fine-adjustment device for a cab turnover mechanism belongs to the technical field of cab turnover mechanisms, and is capable of changing the strength of the tilting force of a torsion bar and leading a cab to turn up or fall down smoothly. The technical scheme of the fine-adjustment device includes that one side of a torsion bar arm (6) parallel to a spline sleeve (201) is provided with an arc-shaped elongated slot hole (202), a fixing bolt (5) penetrating through the arc-shaped elongated slot hole is fixedly connected with a threaded hole correspondingly arranged on the outside of a support (1), an adjusting seat (101) is arranged on the lower portion of the support, and one end of an adjusting bolt (3) is screwed out of a threaded hole of the adjusting seat to be connected with a locking nut (4) in a threaded manner and abutted to one side of the lower portion of the torsion bar arm. The pre-twisting angle of the torsion bar can be changed by adjusting the adjusting bolt abutted to the lower end of the torsion bar arm, and the purpose of adjusting the strength of the tilting force of the torsion bar is achieved, so that torsion moment provided by the torsion bar is matched with gravitational moment formed by the cab around a rotating shaft, and accordingly the cab turns up or falls down smoothly.
Description
Technical field
The utility model relates to a kind of micromatic setting that is used for cab turning mechanism, belongs to the cab turning mechanism technical field.
Background technology
Automobile driving cabin overturning mechanism is a kind of servomechanism of digging operator's compartment when being used for safeguarding the cab-over-engine truck driving engine.The prior mechanical switching mechanism is made of the torsion bar that is installed in the central siphon assembly on the left and right bearing and be arranged in the central siphon, it is fixing that the castellated shaft of torsion bar one end cooperates with the spline endoporus of central siphon one end, and the castellated shaft of the other end passes to cooperate with spline housing on the torsion bar arm from the bearing that is provided with torsion bar arm one side by central siphon and fixes.But because the time there are all accumulated errors in assembling, the power of digging often be not bigger than normal be exactly less than normal, have some setbacks thereby cause operator's compartment to dig or fall.
The utility model content
Technical problem to be solved in the utility model is: be intended to overcome the deficiency of above-mentioned prior art, provide a kind of and can change torsion bar tilting force size, make the smooth and easy micromatic setting that is used for cab turning mechanism of digging or falling of operator's compartment.
Its technical scheme is: a kind of micromatic setting that is used for cab turning mechanism, comprise and be installed in a left side, the central siphon assembly that constitutes by supporting arm and central siphon on the right support abutment, and be arranged on torsion bar in the central siphon, the castellated shaft of torsion bar one end cooperates fixing with the spline endoporus of central siphon one end, the castellated shaft of the other end by central siphon from the bearing that is provided with torsion bar arm one side, pass cooperate with spline housing on the torsion bar arm fixing, it is characterized in that: a side parallel with spline housing on the described torsion bar arm is provided with the arc long lumbar hole, and bolt of rear end plate passes the arc long lumbar hole and is connected and fixed with the last corresponding tapped bore of offering in the bearing outside; The bottom of bearing is provided with adjustment seat, an end of regulating bolt back-out that the tapped bore of adjustment seat is threaded with jam nut and with a side butt of torsion bar arm bottom.
Its technique effect is: when operator's compartment is dug or fallen when having some setbacks, unscrew bolt of rear end plate earlier, make the torsion bar arm in the scope of its arc long lumbar hole, to carry out angular movement around the centre of gration of central siphon, unclamp then on the mast adjustment seat jam nut, adjust adjusting bolt as required with torsion bar arm lower end butt, to change the pre-torsional angle of torsion bar, realize adjusting the purpose of torsion bar tilting force size, torsional moment and operator's compartment that torsion bar is provided are complementary around the gravitational moment that S. A. forms, thereby smoothly operator's compartment are dug or fallen.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of micromatic setting that is used for cab turning mechanism, comprise the central siphon assembly 8 that constitutes by supporting arm 81,82 and central siphon 83 that is installed on the left and right bearing 7,1, and be arranged on torsion bar 6 in the central siphon, it is fixing that the castellated shaft of torsion bar one end cooperates with the spline endoporus of central siphon one end, and the castellated shaft of the other end passes to cooperate with spline housing 201 on the torsion bar arm from the bearing that is provided with torsion bar arm 2 one sides by central siphon and fixes.A side parallel with spline housing 201 on the torsion bar arm is provided with arc long lumbar hole 202, and bolt of rear end plate 5 passes that the corresponding tapped bore of offering is connected and fixed on this arc long lumbar hole and bearing 1 outside.The bottom of bearing is provided with adjustment seat 101, an end of regulating bolt 3 back-out that the tapped bore of adjustment seat is threaded with jam nut 4 and with a side butt of torsion bar arm bottom.
In the time of need carrying out the torsion adjustment, unscrew bolt of rear end plate earlier, make the torsion bar arm in the scope of its arc long lumbar hole, to carry out angular movement around the centre of gration of central siphon, unclamp then on the mast adjustment seat jam nut, adjust the adjusting bolt with torsion bar arm lower end butt as required, to change the pre-torsional angle of torsion bar.After adjusting end, tighten bolt of rear end plate earlier, tighten the jam nut of regulating on the bolt again and get final product.
