Vacuum booster push rod wide with range and with energy-absorbing conquassation function.
The purpose of this utility model can be realized by the following technical scheme: a kind of vacuum booster push rod, including be in
The rod-shaped body of rod, one end of the body of rod are big ball head, and the other end of the body of rod is small ball head, which is characterized in that the body of rod
Including the body of rod one and the body of rod two for being coaxially disposed and being threadedly coupled, the big ball head is located on the body of rod one, the bead
Head is located on the body of rod two, and the body of rod one and/or the body of rod two are equipped with the blind hole being coaxially disposed.
In a kind of above-mentioned vacuum booster push rod, the body of rod one is axially arranged with the screw thread with self-locking thread
Hole, the body of rod two have the external thread section being connected in threaded hole.The body of rod one and the body of rod two are connected by self-locking thread in this way
Rear stable structure is connect, will not be shaken and be loosened；When practical manufacture, the threaded hole with self-locking thread can be set on the body of rod two,
External thread section can be set on the body of rod one.
In a kind of above-mentioned vacuum booster push rod, the body of rod one is equipped with blind hole, the screw thread hole location
At the aperture of blind hole.Prior to processing blind hole on the body of rod one, threaded hole is processed later, it is easy to process in this way.
In a kind of above-mentioned vacuum booster push rod, the blind hole at least extends to one center of the body of rod.In this way
It ensure that energy-absorbing is crushed effect.
In a kind of above-mentioned vacuum booster push rod, it is in six that the outer wall that the body of rod one corresponds to threaded hole, which has,
The flange collar of prism-shaped.Flange collar clamps positioning convenient for the body of rod one when connecting in this way, so that the body of rod one and the threaded connection of the body of rod two are convenient.
In a kind of above-mentioned vacuum booster push rod, the big ball head is cylindrical and two ends are song
Face, the big ball head and the body of rod one are coaxially disposed, and the big ball head is equipped with the groove for being connected to both ends.In this way
Big ball head entirety uniform force, is not easy deformation, and groove facilitates big ball head to insert in other component carry out activity rivetings convenient for exhaust
It connects, and groove reduces abrasion, extend using the longevity convenient for storing lubricant grease to guarantee the lubricant effect at big ball head
Life.
Compared with prior art, this vacuum booster is split type structure with push rod, easily manufactured, and machining accuracy is high, and
And adjustable in length, use scope is wide, and big ball head is easy to connect and long service life, in addition also have the function of energy-absorbing conquassation,
Improve safety.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this vacuum booster push rod includes the body of rod in the shape of a rod, one end of the body of rod is big ball head 1, bar
The other end of body is small ball head 2, and the body of rod includes the body of rod 1 and the body of rod 24 of coaxial arrangement and threaded connection, big ball head 1
On the body of rod 1, small ball head 2 is located on the body of rod 24, and the body of rod 1 and/or the body of rod 24 are equipped with the blind hole being coaxially disposed
5。
It further describes in detail, the body of rod 1 is axially arranged with the threaded hole 6 with self-locking thread in the present embodiment, and the body of rod 24 has
The external thread section 7 being connected in threaded hole 6.The body of rod 1 is equipped with blind hole 5, and threaded hole 6 is located at the aperture of blind hole 5, blind hole 5
One 3 center of the body of rod is extended to, when reality manufactures, under the premise of not influencing push rod normal work, the depth of blind hole 5 is as far as possible
It is deep.
It clamps positioning for the ease of the body of rod 1 to be threadedly coupled to facilitate, the outer wall that the body of rod 1 corresponds to threaded hole 6 has
In the flange collar 8 of hexa-prism.Big ball head 1 is cylindrical and two ends are curved surface, and big ball head 1 and the body of rod 1 are coaxial
Setting, big ball head 1 are equipped with the groove 9 for being connected to both ends, and the quantity of groove 9 is three and circumferential uniformly distributed, ball big in this way
The structural strength on head 1 is high, and big 1 activity riveting of ball head is convenient, and groove 9 can store lubricant grease to guarantee big ball head
Lubricant effect at 1 reduces abrasion, prolongs the service life.
The precision of this vacuum booster 24 separate machined of the body of rod 1 in push rod and the body of rod is high, easily manufactured；When having
After the body of rod 1 of big ball head 1 forms standardized production, such subsequent push rod can only production length it is different there is small ball head
2 body of rod 24, can effectively save production cost and production cycle, in use, the body of rod 1 can be according to vacuum booster row
Range request and the body of rod 24 for matching appropriate length, use scope are wide；In addition in the case where guaranteeing that push rod works normally, blind hole 5
Push rod overall structural strength is reduced, when car crass, push rod stress and deformation at blind hole 5 plays the role of energy-absorbing conquassation, pushes away
Bar entire length shortens, and drives the crumple together of coupled brake pedal, increase brake pedal and driver foot it
Between spacing, reduce and avoid driver foot injure.
