Description
Technical field
The present invention relates to technical field of automobile accessories, more particularly to a kind of vehicle stabilizer bar bushing assembly.
Background technology
The bushing of vehicle stabilizer bar is typically formed by upper and lower two pieces to the molded rubber divided, and is joined by clip for one
Body bag is on stabiliser bar.The bushing of vehicle stabilizer bar on the one hand can restricted stability bar, on the other hand can be provided for stabiliser bar
Certain vibration isolation capability.But current bushing is all gum, not wear-resisting, service life is shorter；And stabiliser bar is serving as a contrast
It can be rotated in set relative to bushing and clip, while also need to axially provide stabiliser bar restraining force, therefore bushing and clip
Between need keeing relative stability property, displacement can not be produced between the two, but current bushing and yoke configurations are simple, fit structure
Design unreasonable, attachment structure is not sufficiently stable between bushing and clip, easily produces displacement.
Vehicle is also considered when inclination is turned, excitation caused by road surface is delivered to bushing by pole, at this moment
Bushing can bear certain stress and torsional friction, also higher to the performance requirement of bushing, and most important is exactly to require product
There is a sufficiently high Static stiffness, good compression set and high and low temperature environment downward driving friction enough has no abnormal sound and 100,000 kilometers
Endurance life.In order to meet that the hardness of bushing that above-mentioned requirements make can be very high, some reach more than 80shoreA, such as
This high durometer rubber certainly will exist because filler too much caused by compression set it is poor, compounding rubber is uneven, vulcanize processing difficulties,
The shortcomings of fatigue life is not unstable, up to standard.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of vehicle stabilizer bar bushing assembly, the bushing of the bush assembly
Wear-resisting intensity is high, and service life length, matching structure design is reasonable between bushing and clip, between bushing and stabiliser bar, and connection is steady
It is fixed, it is not easy to produce displacement；Described bushing Static stiffness is high, compression set is good, and processing characteristics is excellent, fatigue life length.
The technical solution of the present invention is to provide a kind of vehicle stabilizer bar bushing assembly with following structure, including
