Plane (in industry, the plane at custom block selecting rocker motion track place is called X/Y plane) to block selecting rocker motion track place
Having the motion of a Z-direction, and hinged block selecting rocking arm can only move at X/Y plane, block selecting rocking arm cannot follow bulb one
Acting as the motion of Z-direction, the bulb that so relative ball-and-socket tilts the most easily deviates from ball-and-socket, and in bulb tilting procedure, bulb
And form the less linear contact of contact area between ball-and-socket, cause overall shaking volume big.
Utility model content
The technical problems to be solved in the utility model is to provide one, and when block selecting, entirety shaking volume is few and can effectively prevent
The block selecting rocker arm assembly of bulb abjection.
Technical solution of the present utility model is to provide a kind of block selecting rocker arm assembly, including block selecting rocking arm, described choosing
Gear rocking arm is articulated with on the base of block selecting system, also includes ball cover, is provided with block selecting bar with block selecting system in described ball cover
The ball-and-socket that bulb is equipped with mutually, described ball cover is provided with outside cylinder sidewall, and described block selecting rocking arm is provided with interior cylindrical hole, described ball
Set unitary rotation is fitted in interior cylindrical hole.
Described ball cover has on the other end end face relative with ball-and-socket nest mouth on opening, and described ball-and-socket nest wall and sets
Have spaced radial to stitch, and described spaced radial be sewn on the whole height of ball cover extension, the ball cover of this structure injection time just
Bulb mould in molding ball-and-socket is deviate from from the ball-and-socket of ball cover, reduces contraction distortion during injection, and the ball of this structure simultaneously
Set has certain elasticity and is easy to the equipped of bulb.
On the block selecting rocking arm end end face at interior cylindrical hole two ends, there is opening, it is simple to demoulding during injection mo(u)lding.
Be interval with on the inwall of the interior cylindrical hole of described block selecting rocking arm multiple along whole height extend and divide circumferentially
The oil storage tank of cloth, can store lubricant grease in oil storage tank.
The ball-and-socket nest mouth of described ball cover is provided with the conical entrance that internal diameter gradually decreases, and bulb is played guiding by conical entrance
Effect.
This utility model has the advantage that block selecting rocker arm assembly of the present utility model, when block selecting, because of bulb and block selecting
It is provided with ball cover between rocking arm, is provided with ball-and-socket in ball cover and is equipped with mutually with bulb, and ball cover rotates further through outside cylinder sidewall equipped
In the interior cylindrical hole of block selecting rocking arm, after being so articulated with at block selecting rocking arm on the base of block selecting system, when block selecting, ball cover meeting
Move under the drive of block selecting bar together with bulb, and in motor process, even if bulb tilts relative to block selecting rocking arm, because of ball cover
And then bulb action together, bulb does not then fall out ball-and-socket, and when block selecting, is equipped with mutually because being provided with between ball cover with block selecting rocking arm
Outside cylinder sidewall and interior cylindrical hole, form face contact between the two, and face contacts contact face be long-pending big, overall shaking volume is few.

Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings:
As it can be seen, a kind of block selecting rocker arm assembly, including block selecting rocking arm 1, described block selecting rocking arm 1 is articulated with block selecting system
Base 2 on, as shown in the present embodiment Fig. 1, one end of block selecting rocking arm is articulated with on base 2, and block selecting rocking arm is at External Force Acting
Under can swing in certain angle along jointed shaft.In the present embodiment, block selecting rocking arm is working of plastics, is molded into by injection liquid
Type.
Unlike the prior art, block selecting rocker arm assembly of the present utility model also includes ball cover 3, in described ball cover 3
Being provided with the ball-and-socket 5 that bulb 4.1 phase of the block selecting bar 4 with block selecting system is equipped with, described ball cover 3 is provided with outside cylinder sidewall 3.1, institute
The block selecting rocking arm 1 stated is provided with interior cylindrical hole 1.1, and described ball cover 3 unitary rotation is fitted in interior cylindrical hole 1.1.In this enforcement
In example, described ball cover is also working of plastics, by injection liquid injection mo(u)lding.During wherein ball cover is integrally located at interior cylindrical hole, at this
In embodiment, the slightly indentation of the end of ball cover is in the interior cylindrical hole of block selecting rocking arm, and entirety does not stretch out interior cylindrical hole.Overall equipped
Ball cover in interior cylindrical hole, when block selecting, will not interfere respective motion between block selecting rocking arm and ball cover.
Described ball cover 3 has opening on the other end end face relative with ball-and-socket 5 nest mouth, on described ball-and-socket 5 nest wall
It is provided with spaced radial seam 7, and described spaced radial seam 7 extends on the whole height of ball cover 3.In the present embodiment, ball cover
The nest mouth of ball-and-socket, the port i.e. clamp-oned for bulb, and the ball cover other end end face relative with this port is planar end surface, and this end
Face is provided with above-mentioned opening, and this opening is and is arranged at the bottom of ball-and-socket 5 nest and connects with ball-and-socket.After spaced radial seam 7 is arranged,
During injection mo(u)lding ball cover, because of exist between space, the contraction distortion of ball cover when being effectively reduced injection, when the demoulding, spaced radial
Seam makes ball cover just can conveniently deviate from radially with certain elastic force drawn in and launch, the bulb mould being so positioned at ball-and-socket,
Avoid hard draw and make ball cover be pulled, and when equipped bulb, spaced radial seam makes ball cover have elasticity and be easy to bulb
Equipped.
In the present embodiment, for making block selecting rocker structure succinct, the block selecting rocking arm 1 end end face at interior cylindrical hole 1.1 two ends
On there is opening, this opening connects with interior cylindrical hole and makes block selecting rocking arm form open-ended ducted body.
Multiple extension and one-tenth week it is interval with along whole height on the inwall of the interior cylindrical hole 1.1 of described block selecting rocking arm 1
Oil storage tank 6 to distribution.In oil storage tank can storing lubricating grease, decrease ball cover and select the friction between rocking arm, extending two
In the service life of person, decrease replacement frequency.
The ball-and-socket 5 nest mouth of described ball cover 3 is provided with the conical entrance 8 that internal diameter gradually decreases, and conical entrance is to equipped ball
Head can play guide effect, makes that bulb is smooth and easy to be squeezed in ball-and-socket.
Block selecting rocker arm assembly of the present utility model is because having additional ball cover, and ball cover can avoid the abjection of bulb when block selecting, and
Can also increase contact area, reduce shaking volume, and after ball cover is arranged, it is to avoid block selecting rocking arm directly contacts with bulb, extends
The service life of block selecting rocking arm.
