Abstract
The utility model discloses a damper used for a noise silencer. One side of an overcoat 5 is provided with a grease fitting 6, a stop plate 9 is fixedly connected to one end of the overcoat 5, the stop plate 9 is fixedly connected with a lifting eye 10 which is connected with the noise silencer, and a spring retainer 8, an inner spring 7, an outer spring 4 and a spring retainer 3 are orderly sheathed with a draw rod 1 and are installed into an inner cavity of the overcoat 5 simultaneously; a draw rod head 11 of the draw rod 1 closes up to the inner surface of the stop plate 9, the centre hole in a stop plate 2 makes the stop plate 2 fixedly connected to one end of the overcoat 5 after the draw rod 1 passes through the centre hole, and a screw thread end of the draw rod 1 is connected with a crossbeam of the engine. The lifting eye 10 is connected with the noise silencer via an axis hole 12. The vibration produced by the engine is greater than the vibration produced by the automobile frame when the automobile travels, and the noise silencer, the exhaust pipe and the interface pad are easily damaged. Because the connected damper used for a noise silencer is adopted, the noise silencer, the exhaust pipe and the interface pad can be protected. The damper can be applied to various types of automobiles or tractors.
Description
Technical field
The utility model relates to a kind of vibration damper, relates in particular to a kind of silencing apparatus vibration damper that is applied on automobile or the tractor, belongs to the B60D7/00 class.
Background technique
Automobile (passenger vehicle or lorry) motor in traveling process can produce vibration and noise, be to use silencing apparatus (promptly fixing a silencer) in order to reduce the employed method and apparatus of engine noise, and silencing apparatus is installed on the automobile frame usually in the rear end of motor.Before the utility model, the buffering joint of making of a spring between silencing apparatus and motor links to each other, but the vibration owing to motor in vehicle traveling process of sort buffer joint fractures easily greater than the vibration of automobile frame generation, directly influence the working life of silencing apparatus and engine exhaust arm, interface pad, reduce the noise elimination effect of automobile.
Summary of the invention
Task to be solved in the utility model provides a kind of reasonable in design, alternative buffering joint can improve the silencing apparatus silencing apparatus vibration damper in working life again.
For finishing above-mentioned task, the technical solution adopted in the utility model is: design a cylindrical jacket, a grease nipple is installed in a side at this overcoat, (as welding) baffle plate that is connected earlier at overcoat, central position in this baffle plate be connected again (as welding) hanger of axis hole is arranged, one of hanger can be semicircle or square.Having spring-leaf retainer of first suit on the pull bar of drawhead, adjacent this spring-leaf retainer of inner spring and outer spring is sleeved on the pull bar, the length of inner spring and outer spring is near the length of overcoat, adjacent outer spring of another spring-leaf retainer and inner spring also are sleeved on the pull bar, pull bar, two spring-leaf retainers and inner chamber outer, that inner spring all is assemblied in overcoat; Another its centre hole passes that the other end with overcoat is connected behind the pull bar (as welding).
Adopt silencing apparatus that as above technological scheme provides with vibration damper compared with prior art, its beneficial effect is:
1. reasonable in design, compact structure reduce automobile and are in operation to the noise pollution of environment;
2. under the identical prerequisite of manufacture cost, silencing apparatus is 20～30 times that buffering saves working life with the working life of vibration damper, has reduced the consumption that is equipped with accessory, and the replacement cycle that is equipped with accessory has been grown in the court of a feudal ruler;
3. applied widely, be not only applicable to public transit vehicle, also be applicable to large-scale haulage vehicle and tractor.
Description of drawings
Accompanying drawing is the structure cross-sectional schematic of silencing apparatus described in the utility model with vibration damper, also is specification digest accompanying drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in drawings, described silencing apparatus is made of pull bar 1, baffle plate 2 or 9, spring-leaf retainer 3 or 8, outer spring 4, inner spring 7, overcoat 5, grease nipple 6, hanger 10 with vibration damper.Grease nipple 6 is installed in a side of overcoat 5, and it is a prior art, and effect is to inject butter by grease nipple 6 to the inner chamber of overcoat 5, lubricated with the spring-leaf retainer 3 or 8 that guarantees overcoat 5 inner chambers, outer spring 4, inner spring 7, non-corrosive.Baffle plate 9 is connected (as welding) in one of overcoat 5, hanger 10 again with baffle plate 9 affixed (as welding), it is semicircle or square that of hanger 10 can be, and is processed with one and can wears the axis hole 12 that bearing pin can link to each other with automotive muffler on it.One end of pull bar 1 has drawhead 11, and this drawhead 11 can be circle, square or hexagon etc., and pull bar 1 is assemblied in the inner chamber of overcoat 5, and spring-leaf retainer 8 is sleeved on the pull bar 1 near drawheads 11, and spring-leaf retainer 3 or 8 section are multi-level trapezoid shaped.Inner spring 7 is sleeved on the pull bar 1, and one of inner spring 7 is connected with spring-leaf retainer 8; At the outer suit outer spring 4 of inner spring 7, one of outer spring 4 also is connected with spring-leaf retainer 8, and outer spring 4, inner spring 7 can be followed the move left and right of spring-leaf retainer 8 and be compressed or uphold like this.The diameter of outer spring 4 used materials is greater than the diameter of inner spring 7 used materials, and their number of turns can equate or be unequal.The race diameter of outer spring 4 can guarantee like this that less than the intracavity diameter of overcoat 5 outer spring 4 can freely stretch in the inner chamber of overcoat 5.Spring-leaf retainer 3 is sleeved on the pull bar 1 near baffle plates 2, and the center hole of baffle plate 2 passes the other end that is fixed on overcoat 5 behind the pull bar 1, not with an outside of exposing at overcoat 5 of the pull bar 1 of drawhead 11.One of the pull bar 1 that links to each other with the motor crossbeam is processed with threaded end 13.
During enforcement, assemble the silencing apparatus vibration damper according to accompanying drawing, the threaded end 13 by pull bar 1 is connected silencing apparatus on the motorized automotive frame with vibration damper, and uses fixed by nut.With a bearing pin hanger 10 of silencing apparatus with vibration damper is connected with an end of silencing apparatus, and the other end of silencing apparatus links to each other with the engine exhaust arm.
When automobile (as bus or lorry) motor in running can produce vibration clocklike; owing to being installed in, motor causes on the automobile frame that automobile frame produces vibration; but the vibration that motor produced is greater than vibration that automobile frame produced; there is difference in size in vibration; so when the described silencing apparatus of automobile frame and this case links to each other with the pull bar 1 of vibration damper; the frequent vibration that motor and vehicle frame produced makes the inner spring 4 and outer spring 7 frequent stretching in the overcoat 5; their the flexible frequent vibration of silencing apparatus that weakened with vibration damper; can not cause the silencing apparatus and the frame weaving vibration not of uniform size that are attached thereto; vibration to silencing apparatus plays buffer function; silencing apparatus and engine exhaust arm have been protected; interface pad; improve silencing apparatus and engine exhaust arm; in the working life of interface pad, reached purpose described in the utility model.
