Description
Technical field
The utility model belongs to automobile shock equipment technical field, is related to a kind of fluid pressure underpan bushing.
Background technique
Automobile hanging is the core component of an automobile, is the structure for connecting wheel and vehicle body, and main function is to absorb
Impact from various road surfaces to vehicle body guarantees the stabilization for the comfort and vehicle body that passenger takes.Ideal suspension is not only
Vehicle can be made to move up and down with road surface fluctuating, and can make the holding as far as possible during advance of entire vehicle body horizontal whereby, but also
Appropriate, sensitive reaction can be made with the variation of speed, road conditions, motion mode；Meanwhile it can also be such that tire pastes at any time with road surface
It closes, and wheel is made to keep angle appropriate, to enable the power performance of automobile, braking ability and the abundant body of steering behaviour
It is existing.Inhibit concussion when rebound after spring shock-absorbing by this damping device and absorb the energy of road shocks, it is ensured that vapour
The control stability of vehicle, interior noise, improves the comfort and vehicle body of passenger's seating caused by reducing because of Uneven road
Stability.
Summary of the invention
For the utility model in view of the above-mentioned problems, providing a kind of fluid pressure underpan bushing, which can guarantee suspension and vehicle body
Between bonding strength, while cost is relatively low, handling ease, long product lifecycle.
According to the technical solution of the utility model includes: a kind of fluid pressure underpan bushing, it is characterised in that: described including aluminium inner core
Core outer surface vulcanization the first vulcanized rubber of setting in aluminium, metallic framework fitting is set in first vulcanized rubber, and metal
Both ends are bent respectively in aluminium inner core circumferential surface skeleton along its length, and the intermediate position of the metallic framework is curved towards aluminium inner core
Folding forms groove, and the both ends that the outer surface of metallic framework corresponds to groove are set to aluminium inner core by the vulcanization of the second vulcanized rubber
On, the surface of second vulcanized rubber is pressed metal outer pipe, and the axial ends of the metal outer pipe is respectively facing the second vulcanization
The bending of rubber side and with aluminium core surface abutting contact, hydraulic oil is full of in the groove.
The metallic framework is punch forming part as a further improvement of the utility model,.
Distinguish shape in the both ends that the outer surface of the metallic framework corresponds to groove as a further improvement of the utility model,
At circular arc chamfering portion.
The axial ends bending part of the metal outer pipe is arc transition as a further improvement of the utility model,.
It is circle that second vulcanized rubber, which corresponds to the inside at the both ends of groove, as a further improvement of the utility model,
Arc transition.
The utility model has the technical effect that the utility model product structure is simple, compact, reasonable, can guarantee to hang
The bonding strength with vehicle body is hung, manufacturing cost is lower, handling ease, long service life.

Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, 2, the utility model is a kind of fluid pressure underpan bushing, including aluminium inner core 1,1 appearance of aluminium inner core
Face vulcanization the first vulcanized rubber 4 of setting, the fitting of metallic framework 2 is set in first vulcanized rubber 4, and 2 edge of metallic framework
Length direction both ends are bent respectively in 1 circumferential surface of aluminium inner core, and the intermediate position of the metallic framework 2 is bent towards aluminium inner core 1
Groove 2-1 is formed, the outer surface of metallic framework 2 is set to aluminium by the vulcanization of the second vulcanized rubber 5 corresponding to the both ends of groove 2-1
On inner core 1, the surface of second vulcanized rubber 5 is pressed metal outer pipe 3, and the axial ends of the metal outer pipe 3 is respectively facing
The bending of second vulcanized rubber, 5 side and with 1 surface abutting contact of aluminium inner core, hydraulic oil 6 is full of in the groove 2-1.
Metallic framework 2 is punch forming part.
The outer surface of metallic framework 2 is respectively formed circular arc chamfering portion corresponding to the both ends of groove 2-1.
The axial ends bending part of metal outer pipe 3 is arc transition.
Second vulcanized rubber 5 is arc transition corresponding to the inside at the both ends of groove 2-1.
The manufacturing process of the utility model product is as follows: aluminium inner core 1 and metallic framework 2 being passed through the first vulcanization first
Rubber 4, the second vulcanized rubber 5 link together, and the product vulcanizated before is then pressed into metal outer pipe in hydraulic oil 6
In 3, necking operation finally is carried out to the both ends of metal outer pipe 3, so that the product vulcanizated and hydraulic oil 6 are fixed on outside metal
In pipe 3.
The utility model product structure is simple, compact and reasonable, can guarantee the bonding strength of suspension with vehicle body, cost compared with
It is low, handling ease, long service life.
