Description
Technical field
The utility model is related to a kind of automobile steering device bushing, is applied particularly to automobile manufacture industry.
Background technology
The requirement of automobile steering device main shaft protective jacket has higher anti-wear performance, while also need to certain elasticity,
To adapt to the radial pressure and axial friction that steering gear constantly rotates generation, it is ensured that automotive steering structure is stable to be rotated；It is existing
Automobile steering device main shaft typically uses the cylindrical protective set of injection molding in technology, and 6-8 is uniformly distributed in protective jacket outer surface
Bar extends and apart from one another by the open slot staggered from two ends to centre so that protective jacket has certain elasticity；For on protective jacket
Open slot is processed, the injection forming mold of manufacture protective jacket need to circumferentially be uniformly arranged the pull-out type mould of multiple angle directions
Core, core-pulling mechanism is complicated, and cumbersome, mould space-consuming is more, installs standby bulky, low production efficiency.
The content of the invention
It is few that technical problem to be solved in the utility model is to provide a kind of mould core pulling quantity, simple in construction, behaviour
Make convenient automobile steering device bushing.
Automobile steering device bushing of the present utility model, main body is the middle cylinder with the through hole passed through for rotating shaft, cylinder
Barrel upper surface, lower surface be provided with longitudinal opening groove and respectively to corresponding other end extend, open slot end is away from another
End face has the open slot on distance, upper surface, lower surface mutually to stagger on cylinder circumferential position, it is characterised in that：It is described
Lower surface has four the first open slots, respectively in four quadrants that horizontal center line axis, vertical central axis are separated into,
Four the first open slots have a side parallel with vertical central axis；Upper surface has six open slots, two of which
Second opening groove center line is overlapped with horizontal center line axis, and four article of the 3rd open slot is located in four quadrants respectively in addition, and in
Heart line is parallel with vertical central axis；
It is long that first open slot, the second open slot, the 3rd open slot end and the distance of other end are not more than cylinder
The 1/3 of degree；
The cylinder is polyurethane material or polytetrafluoroethylmaterial material by being molded the cylindrical tube of compression molding；
The barrel outer surface has the horizontal toroidal cavity of clamp sealing ring；
The cylinder lower end has outwardly limited step.
Automobile steering device bushing of the present utility model, reduces mould core pulling quantity, simplifies mould structure, production
Occupation area of equipment is small, easy to operate, and production efficiency is high.

Embodiment
As illustrated, the automobile steering device bushing of the present embodiment, main body uses polyurethane material or polytetrafluoroethylmaterial material
By being molded compression molding for cylindrical tube, polyurethane material, polytetrafluoroethylmaterial material wearability are good so that bushing have compared with
High anti-wear performance；Middle through hole is passed through for automobile steering device rotating shaft, and lower end has outwardly limited step 1, automobile
Steering gear rotating shaft is passed through after bushing, and bushing is coordinated by limited step 1 and automobile steering device to be positioned；Barrel outer surface has clamp
The horizontal toroidal cavity 2 of sealing ring, bushing is set in after automobile steering device rotating shaft installs sealing ring 6, sealing ring additional in groove 2
6 tightly tie bushing in rotating shaft tight；The barrel upper surface of cylinder, lower surface set longitudinal opening groove, upper surface, lower surface
Open slot extends to corresponding other end respectively, and there are distance, open slot end and the other end in open slot end far from other end
The open slot that the distance in face is not more than on the 1/3 of barrel lenght, upper surface, lower surface mutually staggers on cylinder circumferential position,
To ensure that bushing had both had the enough intensity that is reliably connected, and there can be good elasticity, production is constantly rotated to adapt to steering gear
Raw radial pressure and axial friction.
Further, lower surface has four the first open slots 3, respectively positioned at horizontal center line axis, vertical central axis
In four quadrants being separated into, four the first open slots 3 have a side parallel with vertical central axis；Upper surface has
Six open slots, the center line of the second open slot of two of which 4 is overlapped with horizontal center line axis, in addition four article of the 3rd 5 points of open slot
Wei Yu not be in four quadrants, and center line is parallel with vertical central axis；During by injection mold injection molding bushing, opening
Groove realizes that four the first open slots 3 of lower surface need to be set vertically upward, down by way of setting pull-out type core rod
The core pulling of both direction；The second open slot 4 that the center line of upper surface two is overlapped with horizontal center line axis need to set level court
It is left, towards the core pulling of right both direction, four articles are located in four quadrants and center line is parallel with vertical central axis the respectively
Three open slots 5 also need to only set it is vertical upward, the core pulling of both direction down；Mould core pulling quantity is reduced, is simplified
Mould structure, production equipment floor space is small, easy to operate, and production efficiency is high.
Yet further, the center line of upper surface four first open slot 3 parallel with vertical central axis, lower surface four
Article have set by the 3rd open slot 5 parallel with vertical central axis of a side it is vertical upward, both direction down
Core pulling can share a core rod drawing mechanism.
Upper end end face extends downwards the second open slot 4, the end face of the 3rd open slot 5 and limited step upper surface are set
Put at grade, facilitate mould to process.
The utility model is related to a kind of automobile steering device bushing, and cylindrical tube lower end has outwardly limiting stand
Rank, barrel outer surface has the horizontal toroidal cavity of clamp sealing ring, and barrel upper surface, the lower surface of cylinder are provided with circumference
The longitudinal opening groove mutually staggered on position, lower surface has four the first open slots 3, respectively positioned at horizontal center line axis, perpendicular
In four quadrants that straight central axis is separated into, four the first open slots have a side parallel with vertical central axis；
Upper surface has six open slots, and the opening groove center line of two of which second is overlapped with horizontal center line axis, four article the 3rd in addition
Open slot is located in four quadrants respectively, and center line is parallel with vertical central axis, reduces mould core pulling quantity,
Mould structure is simplified, production equipment floor space is small, easy to operate, production efficiency is high.
