Description
Technical field
The present invention relates to the technical field of structures of automobile rubber bush more particularly to a kind of drum-type rubber bushings.
Background technique
Currently, what is often touched during vehicle is debugged and looked after and guided is exactly that chassis is looked after and guided, it directly affects vehicle
Drive and comfort.Wherein the rubber hinge bushing on chassis contributes very big, a good lining for the chassis instruction of vehicle
Analysis of Nested Design directly affects manipulation and the comfort on chassis.Height manipulation needs big rigidity to keep stablizing and improve response speed,
Comfort demand rigidity low as far as possible carrys out the excitation of snubber road surface bring, manipulation and it is comfortable between be conflicting.
With the development of the automobile industry, consumer for automobile it is comfortable and handling require it is higher and higher.Currently, existing
The soft connection application of design is not comprehensive, is commonly used in rubber bushing and excessively considers that height is handling in conjunction with comfort
Problem, if comfort is higher in existing product, rubber bushing rigidity is low, handling lower；If handling higher, rubber lining
It is lower to cover rigidity height, comfort.
Summary of the invention
For the problems of above prior art, the present invention provides a kind of high-comfort drum-type rubber lining of high manipulation
It covers, for connecting between body linkage and knuckle, under the premise of guaranteeing vehicle comfort, and can ensure that high handling.
The purpose of the present invention is achieved through the following technical solutions:
A kind of high high-comfort drum-type rubber bushing of manipulation, for connecting between body linkage and knuckle, which is characterized in that packet
Include inner frame, outer skeleton and high elastic rubber；Wherein, the inner frame is intermediate evagination, both ends are parallel to inner frame axis
Line, end are in the hollow cylinder shape structure of horn-like structure；The high elastic rubber is coated on the outside of the inner frame, is two
Hold thin, thick middle structure；Respectively there are a boss, institute far from inner frame both ends, at intermediate projections on the high elastic rubber
It states boss and there is the chamfering with certain angle far from the inner frame side, the outer skeleton inward at both ends is recessed to fall with the boss
Angle is connected, and outer skeleton is coated on the outside of the high elastic rubber；The high elastic rubber is in two sides boss close to medial axis
It is rounding corner structure that, which respectively there are a recess angle, recess angle end in side,.
Further, it can be φ that inner frame both ends diameter, which can be 19.2 ± 0.1mm of φ, intermediate ledge maximum gauge,
25 ± 0.1mm, intermediate ledge arc radius can be 30mm, be respectively falling for 8mm by radius with both ends parallel section
Fillet is connected, and inner frame height can be 42.65mm-42.85mm.
Further, point-blank, and concentricity meets the requirement of Φ 0.8 for the inner frame, outer skeleton central axis.
Further, the inner frame thickness is equal in various pieces.
Further, the rubber bushing diameter can be 36 ± 0.1mm of φ, and the outer skeleton height can be 31mm, described outer
Skeleton thickness is various pieces are all equal, thickness can be 2mm.
Further, the chamfering of the horn-like structure in inner frame end is C0.5.
Further, the high elastic rubber can be 0.5-1.0mm in the original depth close to the inner frame both ends.
Further, the boss thickness can be 0.5-1.0mm, and the chamfering can be 20 °；The two sides boss is relative to interior
Frame center cross section is symmetrical.
Further, the recess angle there are in the boss, one end is close but does not contact high elastic rubber and outer skeleton
Tie point and tie point at a distance of 0.4-0.6mm；The angle angle that is recessed can be 38 ° -40 °；End is rounding corner structure, its radius
It can be 0.5mm.
In the rubber bush structure of the prior art, high elastic rubber uniformly vulcanizes between inner frame and outer skeleton, if rubber serves as a contrast
Set is by greater impact power, then high elastic rubber may cause rubber production due to the mutual extrusion power between inner frame and outer skeleton
Raw expendable deformation is even cracked, and the functionality of rubber bushing is influenced.Using structure of the invention, effectively prevent
In vehicle traveling process, high elastic rubber guarantees the safety in driving process due to being hit power and the deformation generated or cracking
Property and comfort.Meanwhile being combined using structure of the invention, the service life of high elastic rubber is improved, with more economy
Property.
The present invention has the following technical effect that:
(1) rubber bushing provided by the invention has high radial rigidity, can provide enough rigidity to drive, so that the energy such as steering
Enough response quicklies, while the road conditions on road surface can be transmitted to vehicle body.
(2) rubber bushing provided by the invention is in torsion and beat, due to matching for the design of drum type structure and each structure
Close, it made to have lesser rigidity, make automobile when crossing the big road conditions such as bumpy road, can it is softer, keep passenger more comfortable；Together
When, it is ensured that high elastic rubber is not in expendable deformation or cracking in the process of moving, guarantees the safety of passenger.
(3) present invention provides a kind of for connecting the drum type rubber bushing between body linkage and knuckle, with existing skill
Art is compared, because of its structure and combination, its interior drum type skeleton is enable to improve radial rigidity, improves handling, reduction beat, outside
Drum type skeleton improves passenger comfort, to achieve the purpose that comfort and handling combination.It is combined using structure of the invention,
The service life of high elastic rubber is improved, economy is had more.
