Description
Technical field
The invention belongs to vibration damper technical field, specifically the one-piece type vibration damper of silicone oil for a kind of vehicle cab.
Background technique
At present, the operator cabin of each engineering machinery, special vehicle is to be all generally directly mounted on frame, or is indirectly arranged in frame by rubber parts.The environment travelling due to this type of vehicle is all irregular road surface, field, with a varied topography and rise and fall large.The vibration of operator cabin can produce uneasiness psychology extremely to driver, also operator cabin component is produced under Long-term Vibration damage 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 in engineering machinery, especially isolates in the vibration of operator cabin.But nowadays the general silicon oil shock absorber top blind flange adopting is connected without any with rubber, because the long-term operation vibration of operator cabin makes top blind flange produce relative friction displacement with rubber, rubber is with regard to very easily fatigue wear, even destruction.After silicon oil shock absorber oil bowl simultaneously of today adopts, closing in form and rubber are fixed, and also having some silicon oil shock absorbers is 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, has greatly increased the maintenance work in later stage.
Summary of the invention
The present invention is directed to the problems referred to above, provide 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 silicone oil for a kind of vehicle cab, it is characterized in that: comprise be equipped with silicone oil silicone oil chamber, be sealedly attached to the vulcanized rubber part on described silicone oil chamber, described vulcanized rubber Jian runs through at center 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, between described guiding damping fin upper surface and vulcanized rubber part bottom surface, forms shoe cream room; 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 annulus portion, between described vulcanized rubber part and silicone oil chamber, is provided with seal ring; 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 respectively an attachment hole 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, is provided with attachment hole on rhombic plate.
As a further improvement on the present invention, described supporting inner core bottom is formed with groove.
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 good hysteretic characteristic of natural rubber, alleviates the impact of ground vibration on top operator cabin; Product of the present invention bottom is added with Novel high-damping silicone oil in silicone oil chamber, and this silicon oil viscosity characteristic is very large, and larger damping force can be provided, and viscosity with temperature impact is little, can not reduce viscosity because Long-term Vibration heats up.The effectively transmission of insulating noise to operator cabin of this high damping silicone oil simultaneously, increases cab comfort; Product structure of the present invention is simple and reliable, and top blind flange and rubber body sulfuration are in aggregates, improve overall fatigue characteristic, easy for installation, safeguards simply long service life; In product of the present invention, also increase and have overturn-preventing structure, can avoid the danger of toppling of operator cabin in the situation of large load vibration; In product of the present invention, do not establish oil hole, after overall oiling, adopt butt-joint to be connected in and install to connect on ironware, effectively prevent oil leakage phenomenon.
