Description
Technical field
The utility model relates to automobile chassis Brake Design fields, and in particular to a kind of power-assisted push-rod assembly.
Background technique
Power-assisted push-rod assembly plays a part of to input pedal force in electronics booster and transmits input power.Electronics power-assisted at present
Device power-assisted push-rod assembly is that connecting rod, spring, pedal push rod, spring base and circlip are combined together by way of press fitting, bullet
Spring covers in connecting rod, and pedal push rod is in free state.The structure of power-assisted push-rod assembly such as Fig. 1 at present.This power-assisted push rod
Spring base is in dry condition to component at work, causes entire component endurance quality poor, poor work stability, guiding performance
Difference.Spring base and connecting rod are cooperated using wide arc gap, cause pedal push rod guiding performance poor.Simultaneously as spring is placed on company
On extension bar, cause connection bar assembly occupied space in corresponding working region larger.In addition, since pedal push rod is in freely
State, the angle of pedal push rod are unable to get control.
Summary of the invention
The purpose of this utility model is to propose that a kind of novel power-assisted push-rod assembly mentions while reducing radial dimension
The high stability of component, durability and guiding performance, reduce impact force, while enabling to the pedal in pedal push rod component
The freedom degree of push rod controls in lesser range, avoids input power caused by free movement and controls poor phenomenon.
According to power-assisted push-rod assembly provided by the utility model, including pedal push rod and connecting rod, the pedal push rod
One end is inserted in one end of the connecting rod by ball head, is successively arranged circlip and spring along axial direction on the pedal push rod
Seat, the pedal push rod are equipped with the convex shoulder for positioning the spring base, and spiral bullet is equipped between the circlip and spring base
Spring.
Further, the helical spring is the helical spring of cone, and the middle part of the spring base is equipped with and the circle
The round ring boss of the internal diameter adaptation of one end of the helical spring major diameter of taper.Pass through the cone positioned by round ring boss
Helical spring substitute the helical spring in traditional power-assisted push-rod assembly, stability, the guiding of pedal push rod movement can be improved
Property, to improve durability, preferably reduce impact force.
Further, self-lubricating material is coated on the shaft of the connecting rod.Pass through what is play the guiding role in connecting rod
Part substitutes old dry friction material using self-lubricating material, reduces friction noise, improves durability and guiding performance.
Further, the connecting rod is processed using rolling mode with the junction of the pedal push rod and is connect.Pass through rolling
Pressure processing method can guarantee the clearance fit of the ball head of connecting rod inner cylinder and pedal push rod.
The power-assisted push-rod assembly of the utility model has the advantage that compared with traditional power-assisted push-rod assembly
1, improve the job stability of power-assisted push-rod assembly, reduce friction noise, improve guiding performance, improve it is resistance to
Long property；
2, the angle of pedal push rod controls in lesser range, improves the accuracy of input power and input displacement；
3, power-assisted push-rod assembly can buffer a part of feedback force by conical helical spring at work, reduce impact,
Improve the reliability of part.

Specific embodiment
It is such as involved to specific embodiment of the present utility model by the description to embodiment below against attached drawing
The shape of each component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. make
It is further to be described in detail.
Such as Fig. 2-7, the power-assisted push-rod assembly of the utility model, including pedal push rod 1 and connecting rod 2, the one of pedal push rod 1
End is inserted in one end of connecting rod 2 by ball head 11, is successively arranged circlip 3 and spring base 4 along axial direction on pedal push rod 1, is stepped on
Plate push rod 1 is equipped with the convex shoulder 12 for retaining spring seat 4, and helical spring 5 is equipped between circlip 3 and spring base 4.
As preferred embodiment, helical spring 5 is the helical spring of cone, and the middle part of spring base 4 is equipped with and circle
The round ring boss 41 of the internal diameter adaptation of one end of the helical spring major diameter of taper.Pass through the circle positioned by round ring boss 41
The helical spring of taper substitutes the helical spring in traditional power-assisted push-rod assembly, can be improved the movement of pedal push rod 1 stability,
Guiding performance preferably reduces impact force to improve durability.
Preferably, self-lubricating material 21 is coated on the shaft of connecting rod 2.By in the portion that connecting rod 2 play the guiding role
Divide and old dry friction material is substituted using self-lubricating material 21, reduces friction noise, improve durability and guiding performance.
Preferably, connecting rod 2 is processed using rolling mode with the junction of pedal push rod 1 and is connect.By rolling and processing side
Formula can guarantee the clearance fit of the ball head 11 of 2 inner cylinder of connecting rod and pedal push rod 1.
