Description
Technical field
The invention belongs to vibration damper technical field, specifically the one-piece type vibration damper of a kind of vehicle cab silicone oil.
Background technique
At present, the operator cabin of each engineering machinery, special vehicle is all generally directly be mounted on frame, or is indirectly arranged in frame by rubber parts.The environment travelled due to this type of vehicle is all irregular road surface, field, with a varied topography and rise and fall large.The uneasiness that the vibration of operator cabin can produce extreme to driver is psychological, also under Long-term Vibration, produces damage to operator cabin component simultaneously, occurs unpredictable safety issue.
Silicon oil shock absorber is the device that a kind of isolation alleviates vibration, subtracts the extensive use of shock insulation field, especially at the isolating technique of operator cabin in engineering machinery.But nowadays the general silicon oil shock absorber top blind flange adopted is connected without any with rubber, because the long-term operation vibration of operator cabin makes top blind flange and rubber produce Relative friction displacement, rubber, with regard to very easily fatigue wear, even destroys.Silicon oil shock absorber oil bowl of today adopts rear closing in form and rubber to fix simultaneously, also has some silicon oil shock absorbers to be that bottom is provided with oil hole.The design of rear closing in and oil hole all may cause occurring leaking in silicone oil using process, makes defective shock absorber, considerably increases the maintenance work in later stage.
Summary of the invention
The present invention is directed to the problems referred to above, there is provided a kind of vehicle cab silicone oil one-piece type vibration damper, this shock absorber structure is simple, can effectively realize vehicle damping object, this shock absorber design has overturn-preventing structure simultaneously, can avoid the danger of toppling of operator cabin under large load Vibration Condition.
According to technological scheme of the present invention: the one-piece type vibration damper of a kind of vehicle cab silicone oil, it is characterized in that: comprise the silicone oil chamber that silicone oil is housed, the vulcanized rubber part be sealedly attached on described silicone oil chamber, the center of described vulcanized rubber part is run through and is provided with supporting inner core, supporting inner core upper end connects upper cover plate, supporting inner core lower end connects guiding damping fin, forms shoe cream room between described guiding damping fin upper surface and vulcanized rubber part bottom surface; Described guiding damping fin is spacing fixing by supporting inner core bottom lug boss, and guiding damping fin outer end is upwards bent to form annular portion, is provided with seal ring between described vulcanized rubber part and silicone oil chamber; Described vulcanized rubber part is connected with connecting plate sulfuration, and described connecting plate comprises the first plate body, the second plate body that one connects, and wherein the first plate body outer end is supported on the turnup structure of silicone oil chamber open-mouth end, and the second plate body extends to form tubular structure straight down.
As a further improvement on the present invention, described supporting inner core top is provided with screw-threaded counterbore.
As a further improvement on the present invention, described connecting plate is rectangular plate, and offers an attachment hole respectively at four summits place of rectangular plate.
As a further improvement on the present invention, described connecting plate is rhombic plate, and the drift angle of rhombic plate is arc transition shape, and rhombic plate is provided with attachment hole.
As a further improvement on the present invention, groove is formed with bottom described supporting inner core.
Technique effect of the present invention is: product of the present invention is installed between vehicle cab and chassis, adopts high-quality natural rubber, utilizes the hysteretic characteristic that natural rubber is excellent, alleviate the impact of ground vibration on top operator cabin; Product bottom of the present invention is added with Novel high-damping silicone oil in silicone oil chamber, and this silicon oil viscosity characteristic is very large, can provide larger damping force, and viscosity with temperature impact is little, can not reduce viscosity because Long-term Vibration heats up.This high damping silicone oil effectively to the transmission of operator cabin, can increase cab comfort by insulating noise simultaneously; Product structure of the present invention is simple and reliable, top blind flange and rubber body sulfuration in aggregates, improve overall fatigue characteristic, easy for installation, safeguard simple, long service life; Also increase in product of the present invention and have overturn-preventing structure, the danger of toppling of operator cabin when large load can be avoided to vibrate; Do not establish oil hole in the utility model product, adopt butt-joint to be connected to after overall oiling and install on connection ironware, effectively prevent oil leakage phenomenon.
