Description
Technical field
The utility model relates to a kind of heavy-duty car structure technology more particularly to a kind of heavy-duty car leaf spring grasswort installation knots
Structure.
Background technique
In the prior art, for installing the typical structure of heavy-duty car leaf spring grasswort as shown in Figure 1, it can be seen that steel
Plate pin is arranged in two mounting holes of spring block, and leaf spring grasswort is socketed in the middle part of steel plate pin by bushing, the screw thread of steel plate pin
Nut is provided on end, when nut is tightened, nut and plunger can clamp bushing by way of clamping spring block;It is existing
Problem is: in aforementioned structure, lining can only be acted on indirectly by spring block by the locked-up stress that steel plate pin and nut generate
It puts on, in actual production, in order to realize installation, the spacing between spring block two sidewalls must be slightly larger than the axial length of bushing,
Bushing could be so installed in place, this is resulted between spring block and bushing, and there are gaps, when nut is tightened, the two of spring block
A side wall will deformation occurs, and after installing, the stress that spring block restores deformation can also be acted on steel plate pin, is unfavorable for steel plate
The stress of pin, moreover, spring block restore deformation stress can weaken steel plate pin locking effect, after long-time service, spring block and
It is easy to appear gap between bushing, causes to expose in the middle part of steel plate pin, load will act directly on the exposed of steel plate pin
Position finally will lead to steel plate pin fracture;Deformation occurs for spring block in order to prevent, can also install between spring block and bushing
Gasket, but in actual operation, since the gap between spring block and bushing is smaller, operation is very difficult, and due to processing
The presence of error, spacer thickness needed for different installation positions is not also identical, if Field adjustment spacer thickness, will lead to production
Efficiency declines to a great extent.
Utility model content
For the problems in background technique, the utility model proposes a kind of heavy-duty car leaf spring grasswort mounting structure,
Innovation is: the heavy-duty car leaf spring grasswort mounting structure is by spring block, steel plate pin, clamping screw, leaf spring, bushing and locking
Nut composition;
The section of the spring block be it is inverted U-shaped, the first mounting hole is provided on the spring block side wall in inverted U-shaped left side, it is inverted U-shaped
It is provided with the second mounting hole on the spring block side wall on right side, the aperture of the aperture of the first mounting hole less than the second mounting hole;Second
It is arranged jagged on spring block side wall on the downside of mounting hole, the second mounting hole is connected to by notch with spring block lower end surface, notch two
Locking screw keyhole is provided on the structural body of side;
The steel plate pin sequentially forms thread segment, path section, major diameter section and plunger from left to right;The screw thread section surface is set
It is equipped with external screw thread, the path section and major diameter section are cylinder;The externally threaded outside diameter is less than the diameter of path section,
The diameter of path section is less than the diameter of major diameter section, and the diameter of major diameter section is greater than the outer diameter of plunger;
The grasswort of the leaf spring is arranged at the position in spring block between the first mounting hole and the second mounting hole, bushing set
It connects in the inner hole of grasswort;The diameter of the path section is matched with bushing inner hole, and steel plate pin is plugged in bushing inner hole, thread segment
Left end from the left side of the first mounting hole protrude, the left side of major diameter section and the right end face contact of bushing, major diameter section are socketed in
In second mounting hole;The locking nut is threadedly coupled with thread segment, when locking nut is by steel plate pin locked, the left end of major diameter section
Bushing is pushed against on the right side of the first mounting hole by face;The clamping screw is arranged in locking screw keyhole, clamping screw energy
The notch is locked, holds the second mounting hole by the major diameter section tightly.
Referring to fig. 2, Fig. 2 is the structural schematic diagram of the utility model, and in assembly, first grasswort is placed in first in spring block
Position (bushing has shifted to an earlier date pre- in the inner hole of grasswort) between mounting hole and the second mounting hole, then make steel plate pin from the right side to
It is inserted into, then with locking nut by steel plate pin locked, is finally again locked the second mounting hole by clamping screw leftly;From front
Explanation can be seen that using after the utility model, bushing is no longer clamped by the two side walls of spring block, but by leaf spring
The left side wall and steel plate pin of seat clamp to realize, this can deformation occurs to avoid the two side walls of spring block, to eliminate phase
The negative stress answered, compared with the prior art, the axial stress being subject on steel plate pin is smaller, and locking effect is also more preferable;Locking screw
After bolt locks the second mounting hole, the second mounting hole can hold the major diameter section of steel plate pin tightly, can prevent steel plate pin from rotating;Pin
Head is for positioning when installing, and when installation locking nut, is clamped plunger with tool, avoidable steel plate pin rotates.
Preferably, the plunger is outer square structure.
Preferably, interior square structure is provided on the right side of the plunger.
The advantageous effects of the utility model are: proposing a kind of heavy-duty car leaf spring grasswort mounting structure, the structure
The stress that steel plate pin can be improved guarantees that the locking effect of steel plate pin is permanently effective, and installs easy to operate.
