Description
Technical Field
The utility model relates to a bumper shock absorber technical field especially relates to a bumper shock absorber with second grade is slowed down.
Background
The shock absorber is used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping.
The existing shock absorber is mostly carried out in a single-stage mode, the resilience force of a large degree still exists when self reciprocating motion is restrained, the vehicle body jumps to a certain degree, and riding experience is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: the shock absorber with the two-stage speed reduction function is provided for solving the problem that the shock absorption effect of the shock absorber with the single-stage shock absorption mechanism is poor.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a bumper shock absorber with second grade is slowed down, includes slide bar and sliding sleeve at the first sleeve pipe and the second sleeve pipe of slide bar one end, the fixed cover of one end fixedly connected with of slide bar is kept away from to first sleeve pipe and second sleeve pipe to the hierarchical chamber of the equal fixedly connected with in the same one side of two fixed covers, and communicate between hierarchical chamber and the fixed cover.
As a further description of the above technical solution:
and one end of the sliding rod, which is far away from the fixed sleeve, is provided with a thread groove.
As a further description of the above technical solution:
and a screw is in threaded connection with the central line of the grading cavity.
As a further description of the above technical solution:
the grading cavity is fixedly connected with the fixed sleeve through a bolt.
As a further description of the above technical solution:
the two fixing sleeves are respectively welded with a first connecting block and a second connecting block.
As a further description of the above technical solution:
three mounting holes are formed in the first connecting block, and a mounting hole is formed in the second connecting block.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
the utility model discloses in, two slide bars all slide to in first sleeve pipe and the second sleeve pipe, extrude sheathed tube inside, its inside hydraulic oil is pushed to inside the fixed cover, the volume in sliding sleeve and the fixed cover reduces, restrain the motion of hydraulic oil, and simultaneously, hydraulic oil passes through the passageway of connection, move to hierarchical chamber, because the diameter of connecting channel between hierarchical chamber and the fixed cover is less, the speed that hydraulic oil gets into is slower, do not influence the shock attenuation effect when the slide bar moves to in the sleeve pipe, and delay the follow-up inside slip of slide bar, when having the buffering, have fine suppression to elasticity; when the slide bar is pushed back, the slide bar is pushed back by the hydraulic oil with the increased pressure inside the fixing sleeve, the pressure in the sleeve is smaller than that in the grading cavity when the slide bar moves to a certain degree, the hydraulic oil in the grading cavity is sucked into the fixing sleeve through the pipeline, and therefore the force of the slide bar, which needs to be partially drawn out, is used for extracting the hydraulic oil, the slow motion of the slide bar is realized, and the speed reduction effect of the damping mechanism is improved in a grading mode.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bumper shock absorber with second grade is slow, including slide bar 1 and sliding sleeve at first sleeve pipe 2 and the second sleeve pipe 6 of slide bar 1 one end, it is sealed between slide bar 1 and first sleeve pipe 2 and the second sleeve pipe 6, first sleeve pipe 2 is the same with the specification of second sleeve pipe 6, the fixed cover 3 of one end fixedly connected with of slide bar 1 is kept away from to first sleeve pipe 2 and second sleeve pipe 6, and the hierarchical chamber 9 of the equal fixedly connected with in one side of two fixed covers 3, and communicate between hierarchical chamber 9 and the fixed cover 3.
Specifically, as shown in fig. 1-3, a threaded groove is formed at one end of the sliding rod 1 away from the fixed sleeve 3, so as to facilitate the fixed connection with an external connecting piece.
Specifically, as shown in fig. 1-3, a screw 7 is screwed at the central line of the grading cavity 9, and the grading cavity 9 is fixedly connected with the fixed sleeve 3 through a bolt 8.
Specifically, as shown in fig. 1, a first connecting block 4 and a second connecting block 5 are welded on two fixed sleeves 3, three mounting holes are formed in the first connecting block 4, the mounting holes in the middle position are used for mounting the shock absorber, two edges of the mounting holes are used for mounting the brake disc, and a mounting hole is formed in the second connecting block 5.
The working principle is as follows: when the device is used, when the external vibration force is applied, the two sliding rods 1 slide towards the first sleeve 2 and the second sleeve 6 to extrude the inside of the sleeves, the hydraulic oil in the sliding sleeves is pushed to the inside of the fixed sleeves 3, the volumes of the sliding sleeves and the fixed sleeves 3 are reduced, the movement of the hydraulic oil is inhibited, meanwhile, the hydraulic oil moves towards the grading cavity 9 through the connected channels, and as the diameter of the connecting channel between the grading cavity 9 and the fixed sleeves 3 is smaller, the entering speed of the hydraulic oil is slower, the damping effect of the sliding rods 1 moving towards the sleeves is not influenced, the subsequent sliding of the sliding rods 1 towards the inside is delayed, and the device has buffering function and good inhibition on elasticity; when the slide bar 1 is pushed back, the slide bar 1 is pushed back by the hydraulic oil with the increased pressure inside the fixed sleeve 3, the pressure in the sleeve is smaller than the pressure in the grading cavity 9 when the slide bar 1 moves to a certain degree, the hydraulic oil in the grading cavity 9 is sucked into the fixed sleeve 3 through a pipeline, and therefore the force of part of motion of the slide bar 1 needs to be extracted to the hydraulic oil, the slide bar slowly moves, and the deceleration effect of the damping mechanism is improved in a grading mode.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
