Abstract
The invention discloses an oil leakage-prevention hydraulic damp bush comprising a rubber main spring, a limiting block (2), a buffering block (3) and an outer pipe (5) formed by vulcanizing an inner pipe (1), a support framework (4) and a rubber body (6), wherein at least two sealing ribs (7) are arranged at two ends of the rubber main spring respectively. The invention also discloses a manufacturing method of the oil leakage-prevention hydraulic damp bush. By adopting the technical scheme, for the oil leakage-prevention hydraulic damp bush, the structure is simple, and by adopting a double-layer sealing rib structure and a step and inclined surface locking structure, liquid can be ensured to not leak from the bush under the condition that the bush is subject to load of axial direction, radial direction, torsion and the like, therefore, the conditions of abnormal noises and the like can be avoided, an engine can be ensured to provide large damp and high rigidity so as to provide good vibration isolation and reduction effects for an automobile under the conditions of low frequency and large amplitude, and the service life of products can be prolonged.

Described rubber spring and outer tube interference fit make the outer tube two ends form step and inclined-plane respectively.
The angular range on described inclined-plane is 4 °～8 °.
The manufacturing process of described manufacture method is:
Interior pipe, support frame and rubber body were heated 8～10 minutes, and temperature is controlled at 155 ℃～170 ℃, and pressure control is carried out vulcanizing treatment at 16MPa～20MPa and is integral, and forms rubber spring;
In damp liquid with described rubber spring with assembling pressure 10～15KN, monolateral 0.1mm magnitude of interference is pressed in the outer tube, forms rubber spring and outer tube interference fit;
The model of described damp liquid is an ethylene glycol;
Make the outer tube two ends form step locking and inclined-plane locking by interference fit and sealed muscle;
With limiting stopper pack into locking after lining in;
Buffer stopper is packed in the hydraulic damping lining.
Adopt technique scheme, this leakproof fluid pressure drag Buddhist nun lining provided by the present invention, simple in structure, adopt double-layer seal muscle structure, step and inclined-plane locking mechanism, guaranteed hydraulic bushing be subjected to axially, radially, reverse etc. under the situation of load, liquid that can not spills from lining, thereby avoided the generation of situations such as abnormal sound, guaranteed that motor can provide big damping, big rigidity when low frequency, large amplitude, for automobile provides good vibration isolation, effectiveness in vibration suppression and the working life of having improved product.
