After the signal panel is integrated on the silicon oil damper, the device eliminates the influence caused by the increase of the thickness of the silicon oil damper, so that the installation space of the engine is more compact, the whole volume and weight of the engine are reduced, and the energy consumption and cost of the engine are reduced.

Description

Novel silicone oil damper assembly

Technical Field

The utility model relates to an automobile manufacturing technical field especially relates to a novel silicon oil shock absorber assembly.

Background

The front end of the crankshaft is usually the largest in torsional amplitude value because the rear end of the crankshaft is provided with a flywheel with large inertia, and a shock absorber is usually arranged at the front end of the crankshaft of the engine in order to reduce the torsional vibration of the crankshaft and protect the safety of the crankshaft. Common crankshaft dampers include rubber dampers and silicone oil dampers, which are generally used under conditions of high power and high detonation pressure. In order to avoid interference between the silicone oil damper and other parts at the front end of the engine, the excircle of the damper generally cannot be too large, but in order to meet the requirement of reducing torsional vibration of a crankshaft, an inertia ring in the silicone oil damper generally needs larger inertia, so that the thickness of the silicone oil damper can only be increased, and the increase of the thickness of the silicone oil damper can increase the overall axial size of the engine and influence the arrangement of the engine on the whole vehicle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: aiming at the problems, the installation space of the front end of the engine is reduced, and then a signal panel part connected with the silicone oil damper in series is installed on the excircle of the silicone oil damper in an interference mode. The combination of the two products saves the installation space of the front end of the engine and leads the structure of the front end of the engine to be more compact.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel silicone oil damper assembly comprises a signal panel (1), a shell (2), an inertia ring (3) and a cover plate (4);

the shell (2) is a circular ring with a cavity inside, the inertia ring (3) is placed in an inner cavity of the shell (2), the shell (2) and the inertia ring (3) are separated by a polytetrafluoroethylene circular ring plate liner, a section of step is processed at the top end of the outer circle of the shell (2), the signal disc (1) is pressed onto the step at the top end of the outer part of the shell (2) in an interference manner through a hydraulic machine and a positioning tool after being heated by high-temperature engine oil, and the cover plate (4) is buckled and welded with the shell (2) in an electron beam welding manner;

and after the whole product is vacuumized, silicone oil is filled in the oiling and filling machine, and the silicone oil is filled in a space between the shell (2) and the inertia ring (3).

The utility model has the advantages that: after the signal panel is integrated on the silicon oil damper, the device eliminates the influence caused by the increase of the thickness of the silicon oil damper, so that the installation space of the engine is more compact, the whole volume and weight of the engine are reduced, and the energy consumption and cost of the engine are reduced.

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.

Referring to fig. 1, a novel silicon oil damper assembly comprises a signal panel 1, a housing 2, an inertia ring 3 and a cover plate 4.

The shell 2 is a ring with a cavity inside, the inertia ring 3 is placed into the inner cavity of the shell 2, the shell 2 and the inertia ring 3 are separated through a polytetrafluoroethylene ring plate liner, a section of step is processed at the top end of the outer circle of the shell 2, the signal panel 1 is pressed into the step at the top end of the outer circle of the shell 2 through a hydraulic press and a positioning tool in an interference manner after being heated by high-temperature engine oil, and the cover plate 4 is connected with the shell 2 in a buckling and welding manner in an electron beam welding manner. Then, the whole product is vacuumized and filled with silicone oil through an oiling and filling machine, and the silicone oil is filled into a space between the shell 2 and the inertia ring 3.

The single part of the signal panel 1 is eliminated, the signal panel 1 is installed on the outer circle of the silicon oil shock absorber in an interference mode, and the newly designed silicon oil shock absorber has the shock absorption effect of the shock absorber and keeps the function of transmitting signals to the sensor through the signal panel.

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.
