Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.It is practical below in conjunction with attached drawing 1 and 2 pairs of sheets of attached drawing
It is novel to be described in detail.
A kind of push-rod assembly for gearbox provided by the utility model, including the body of rod 1, for lockking park pawl
Latch fitting 2 and spring 3 for resetting the latch fitting 2,2 pivot bush unit of latch fitting is in the body of rod 1, the body of rod
1 one end is provided with the first locating part 11 for being limited to the latch fitting 2, one end of the spring 3 and the latch fitting 2
It contradicts, the other end is connected with gasket 4, and the side of the body of rod 1 is provided with the second limit for being limited to the gasket 4
Part 12, the gasket 4 are contradicted with second locating part 12.
Current automatic catch automobile, park pawl are all to be rotationally connected with car body, and one end of park pawl is supported with push rod
Touching, the other end is for protruding into parking gear, and the utility model is to realize to connect by the gear rod of intermediary agency and automobile,
And be moved forward and backward by gear rod by intermediary agency's driving.By taking Fig. 1 as an example, when the automobile for being equipped with the utility model needs to hang P
When gear, the body of rod 1 is controlled by intermediary agency by gear rod and is moved right, so that one end that latch fitting 2 controls park pawl is advanced, so that
The other end of park pawl is caught between the wherein two neighboring grinding tooth of parking gear, so that park pawl stalls and makes
Parking of automobile.Before parking gear stop motion, one inclined punching of park pawl can be applied to because colliding with park pawl
Power is hit, which is transferred to latch fitting 2 by park pawl, at this time due to there is the presence of spring 3, can rely on 3 deformation of spring
Mode carry out buffering counteracting come a component to the impact force, to reduce impact force suffered by the body of rod 1, and spring
2 can also assist latch fitting 2 to withstand park pawl, to prevent park pawl to be spontaneously decoupled parking gear, so the utility model
Under the premise of can block park pawl, additionally it is possible to slow down the power that park pawl is applied to the body of rod 1, so that the body of rod 1 be avoided to receive
To impact force it is excessive and cause to damage；And need latch fitting 2 be detached from park pawl when, only need to control gear rod drive the body of rod 1 to
It moves left, under the first locating part 11 and the drive for restoring deformation with spring 3, pulls latch fitting 2 that latch fitting 2 is made to be detached from parking spine
Then pawl is detached from parking gear under the action of the return member that park pawl carries, so that automobile can move.
In addition to this, the setting of gasket 4, for increasing the contact area of spring 3 and the second locating part 12, so that spring 3
It is more uniformly stressed.
In the present embodiment, the spring 3 and the gasket 4 are sheathed on outside the body of rod 1, so that spring 3 will not be to
Deformation occurs for side mistake power, so as to avoid spring 3 because to fractureing caused by due to the deformation of side.
In the present embodiment, the body of rod 1 includes latching portion 16 and the control unit 17 for connecting with the latching portion 16,
First locating part 11 and second locating part 12 are all set in the latching portion 16, and the control unit 17 is provided with third
Locating part 13.Keeping off rod is to be attached by intermediary agency with the utility model, and control unit 17 is relative to latching portion 16
Bending setting, then be to make the connection area of intermediary agency and the utility model bigger；The setting of third locating part 13 is then
In order to be caught in intermediary agency, so that connection effect is more stable.
Preferably, the latching portion 16 is integrally formed with the control unit 17, first locating part 11 and the latching
Portion 16 is integrally formed.Specifically, it is used as the body of rod 1 after can bending using pier bar, and the pier nose of pier bar is then used as the first locating part
11, after latch fitting 2, spring 3 and gasket 4 are once inserted in the body of rod 1, limited by rushing flat at the second locating part 12 and third
Part 13.So that the body of rod 1, the first locating part 11, the connection of the second locating part 12 and third locating part 13 are more stable.
Described one end of the body of rod 1 is provided with the first recessing groove 14 in the present embodiment, and first locating part 11 is set
It is equipped with the second recessing groove 15, first recessing groove 14 is connected to second recessing groove 15, to control latch fitting 2 in the body of rod 1
It when exiting park pawl, steps down, to avoid blocking park pawl and causing to interfere to the work of park pawl.Specifically
, the first recessing groove 14 and the second recessing groove 15 be the body of rod 1 and the first locating part 11 respectively made of turnning and milling.
In the present embodiment, the latch fitting 2 is provided with for the inclined-plane 21 with the cooperation of the grinding tooth of park pawl, the inclined-plane 21
To increase the contact area between latch fitting 2 and the grinding tooth of park pawl, thus reduce when grinding tooth and latch fitting 2 collide latch fitting 2 by
The pressure arrived.
The above is only the utility model preferred embodiment, is not made in any form to the utility model
