Abstract
The utility model discloses a kind of novel leading arm bracket locking mechanisms, belong to commercial vehicle art of suspension systems field, including leaf spring guiding arm support, anti-attrition gasket, leaf spring guiding arm assembly and leading arm grasswort bushing；The leading arm grasswort bushing press-mounting is in the grasswort hole of leaf spring guiding arm assembly, anti-attrition gasket is mounted on the inner sleeve of leading arm grasswort bushing, leaf spring guiding arm assembly and anti-attrition gasket are mounted on as a whole in the home record of leaf spring guiding arm support, and leaf spring guiding arm assembly, anti-attrition gasket and leaf spring guiding arm support are connected by leaf spring pin with leaf spring pin nut.The structure increases clamping screw as leaf spring pin, while in leaf spring guiding arm support one end using the screwed pin shaft in end, guarantees stent clamping leaf spring pin, effectively convenient for assembly and maintenance；Increase anti-attrition gasket between bracket and leading arm, can reduce the stress of leading arm grasswort bushing under lateral operating condition, improve the service life of bushing.
Description
Technical field
The utility model belongs to commercial vehicle art of suspension systems field, and in particular to a kind of novel to be suitable for leaf spring
The bracket locking mechanism of leading arm and air suspension leading arm.
Background technique
Currently, the bracket locking mechanism of leaf spring leading arm and air suspension leading arm is all made of bolt locking.The knot
Structure generates axial pre tightening force and clamping screw clamping force by tightening leaf spring pin nut, guarantees that bracket and leading arm clamp.
Current locking mechanism is primarily present following problems:
1, the rigidity of bracket is larger, clamps difficult；Only it is difficult to clamp by the pretightning force of leaf spring pin nut；
2, the gap of leading arm and bracket is larger, and the lateral operating condition stress of leading arm grasswort bushing is larger, easy to damage.
Utility model content
The purpose of the utility model is to provide a kind of novel leading arm bracket locking mechanism is provided, existing skill can solve
The above problem present in art, while meeting the reliability requirement of vehicle.
The utility model is achieved through the following technical solutions:
A kind of novel leading arm bracket locking mechanism, including leaf spring are oriented to arm support 1, anti-attrition gasket 2, leaf spring pin
3, leaf spring pin nut 4, leaf spring are oriented to arm assembly 5, bracket clamping screw 6, leading arm grasswort bushing 7, bracket locking nut
8；The leading arm grasswort bushing 7 is fitted in the grasswort hole of leaf spring guiding arm assembly 5, and anti-attrition gasket 2 and leading arm are rolled up
7 clearance fit of ear bushing, leaf spring guiding arm assembly 5 and anti-attrition gasket 2 are mounted on leaf spring guiding as a whole
In the home record of arm support 1, leaf spring guiding arm assembly 5 and anti-attrition gasket 2 are fixed on by leaf spring pin 3 and leaf spring pin nut 4
Leaf spring is oriented on arm support 1, and the shaft shoulder on leaf spring pin 3 is pressed against leading arm grasswort bushing 7 and anti-attrition gasket 2.
Further, one end of the leaf spring pin 3 is oriented to arm support 1 with leaf spring by itself screw thread and connect, separately
It is locked by bracket clamping screw 6 and bracket locking nut 8 one end.
Compared with prior art, as follows the advantages of the utility model:
The novel leading arm bracket locking mechanism of one kind of the utility model, is suitable for 4X2,6X4,6X2 lifting bridge etc.
Vehicle with leaf spring leading arm air suspension, using the screwed pin shaft in end as leaf spring pin, while in steel plate bullet
Spring is oriented to arm support one end and increases clamping screw, can effectively guarantee stent clamping leaf spring pin, convenient for assembly and maintenance；It is propping up
Increase anti-attrition gasket between frame and leading arm, can reduce the stress of leading arm grasswort bushing under lateral operating condition, greatly improve lining
The service life of set；The mechanism is not limited by stiffness of support, can guarantee its reliability with the intensity of reinforced support.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the novel leading arm bracket locking mechanism of one kind of the utility model；
Fig. 2 is the sectional view of the novel leading arm bracket locking mechanism of one kind of the utility model；
In figure: leaf spring is oriented to arm support 1, anti-attrition gasket 2, leaf spring pin 3, leaf spring pin nut 4, leaf spring leading arm
Assembly 5, bracket clamping screw 6, leading arm grasswort bushing 7, bracket locking nut 8.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.

8；The leading arm grasswort bushing 7 is fitted in the grasswort hole of leaf spring guiding arm assembly 5, and anti-attrition gasket 2 and leading arm are rolled up
7 clearance fit of ear bushing, leaf spring guiding arm assembly 5 and anti-attrition gasket 2 are mounted on leaf spring guiding as a whole
In the home record of arm support 1, leaf spring guiding arm assembly 5 and anti-attrition gasket 2 are fixed on by leaf spring pin 3 and leaf spring pin nut 4
Leaf spring is oriented on arm support 1, and the shaft shoulder on leaf spring pin 3 is pressed against leading arm grasswort bushing 7 and anti-attrition gasket 2.
Further, one end of the leaf spring pin 3 is oriented to arm support 1 with leaf spring by itself screw thread and connect, separately
It is locked by bracket clamping screw 6 and bracket locking nut 8 one end.
The locking mechanism is connected on leading arm grasswort bushing 7 by anti-attrition gasket 2, and anti-attrition gasket 2 and leading arm are rolled up
Ear bushing 7 is fitted into together in the interior crotch of leaf spring guiding arm support 1, and the axial direction of generation is tightened by the screw thread on leaf spring pin 3
Power clamps anti-attrition gasket and bushing, is then locked again with leaf spring guiding arm support 1, bracket clamping screw 6 and bracket locking
Nut 8 clamps leaf spring pin 3.
