Abstract
The utility model belongs to the vibration buffering technology for a motorcycle, and provides a buffer device for axial vibration of a crankshaft, which is characterized in that the buffer device is provided with a buffer cushion (4) which is arranged between a main bearing of the crankshaft (3) and a box body (5); the buffer cushion (4) comprises an alloy steel skeleton (1) and rubber bosses (2); the alloy steel skeleton (1) is in an annular structure, the inner diameter of the alloy steel skeleton is larger than the outer diameter of the inner ring of the main bearing of the crankshaft, and the outer diameter of the alloy steel skeleton is smaller than the outer diameter of the outer ring of the main bearing of the crankshaft; the alloy steel skeleton (1) is provided with a plurality of mounting holes (6) uniformly distributed along the circumference; and the rubber bosses (2) are positioned in the mounting holes of the alloy steel skeleton, and two ends of each rubber boss extend out of the mounting hole. The buffer device disclosed by the utility model solves the problems of vibration and abnormal sound caused by axial float of the existing engine crankshaft of the motorcycle, and has the characteristics of low cost, practicability and convenience.
Description
Technical field
The utility model belongs to motor-driven two-wheeled motor vehicle Vibrant buffer technology, relates generally to a kind of damping device of bent axle axial vibration.
Background technique
When engine running; The join alternating stress of generation of the rotating inertia force that the reciprocal inertia force that is produced by piston assembly, connecting rod small end and crank, connnecting rod big end produce; All concentrate on the crankshaft group, produced inevitable vibration when making the crankshaft rotating motion.When bent axle axial clearance is excessive when not having suitable buffer structure, can produce play and send abnormal sound, brought hidden danger for crankshaft operation and motor proper functioning.
Summary of the invention
The purpose of the utility model is the damping device that proposes a kind of bent axle axial vibration, makes it can solve existing motorcycle engine crankshaft and exists axial float to cause the problem of vibration and abnormal sound, and have low, the practical and convenient characteristics of cost.
The utility model realizes that the technological scheme that its goal of the invention is taked is: a kind of damping device of bent axle axial vibration, and described damping device has cushion pad, is arranged between the main bearing and casing of bent axle; Described cushion pad comprises alloyed steel skeleton and rubber boss; Described alloyed steel skeleton is a loop configuration, and its internal diameter is greater than the main bearing inner ring external diameter of bent axle, and external diameter is less than the main bearing outer ring external diameter of bent axle; On described alloyed steel skeleton, have a plurality of mounting holes that are uniformly distributed along the circumference; Described rubber boss is positioned at a plurality of mounting holes of alloyed steel skeleton, and mounting hole is stretched out at the two ends of rubber boss.
The damping device of a kind of bent axle axial vibration that the utility model proposes when engine crankshaft is installed, can make rubber boss on the cushion pad produce the amount of deformation of a little, makes and combines closely between bent axle, cushion pad and the casing; When bent axle receives axial force; Cushion pad can be with this axial force buffering, reduces bent axle axial vibration and because vibration causes the effect of abnormal sound, has solved existing motorcycle engine crankshaft and existed axial float to cause the problem of vibration and abnormal sound thereby play; And have low, practical and convenient characteristics of cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model medium alloy steel skeleton.
Fig. 3 is the structural representation of rubber boss in the utility model.
Fig. 4 is the assembling schematic representation of the utility model.
Among the figure: 1, alloyed steel skeleton, 2, the rubber boss, 3, bent axle, 4, cushion pad, 5, casing; 6, mounting hole.
Embodiment
The embodiment who provides in conjunction with accompanying drawing further specifies the utility model:
As shown in Figure 4, a kind of damping device of bent axle axial vibration, described damping device has cushion pad 4, is arranged between the main bearing and casing 5 of bent axle 3; As shown in Figure 1, described cushion pad comprises alloyed steel skeleton 1 and rubber boss 2; In conjunction with Fig. 2, described alloyed steel skeleton 1 is a loop configuration, and its internal diameter is greater than the main bearing inner ring external diameter of bent axle 3, and external diameter is less than the main bearing outer ring external diameter of bent axle 3; On described alloyed steel skeleton 1, have a plurality of mounting holes that are uniformly distributed along the circumference 6; Described rubber boss 2 is positioned at a plurality of mounting holes 6 of alloyed steel skeleton, and mounting hole is stretched out at the two ends of rubber boss 2.
Cushion pad 4 is installed between bent axle 3 and the casing 5, and when again engine crankshaft 3 being installed, at this moment the rubber boss 2 of cushion pad 4 can produce the amount of deformation of a little, makes and combines closely between bent axle 3, cushion pad 4 and the casing 5; When bent axle 3 received axial force, the rubber boss 2 on the cushion pad 4 can cushion this axial force, thereby plays the effect that reduces to vibrate and vibrate abnormal sound.
