Abstract
The automobile vacuum booster control stick of the utility model, the body of rod have bulb with oil pump piston connecting pin；Body of rod stage casing is provided with positive stop lug boss, and the circular ring shape limit ribs of protrusion are provided on positive stop lug boss supporting surface, and positive stop lug boss width dimensions are more than the projection width size of conventional lever；Body of rod length is more than conventional lever length, in same pedal force and under trampling amplitude conditions, can increase effective travel, improve braking efficiency；Positive stop lug boss provides limiting by limit ribs for spring, improves limiting unfailing performance, mechanism stable connection.
Description
Technical field
The utility model is related to a kind of automobile vacuum booster control sticks.
Background technology
Automotive brake also needs auxiliary with oil pressure by vacuum booster in addition to skid resistance is provided by mechanical brake system
Brake system is helped to improve braking quality, to ensure vehicle driving safety coefficient；The vacuum booster of automobile is stopped with oil pressure auxiliary
Vehicle system is generally drawn in brake by oil pump control stick and rubber sleeve oil compression rod and provides oil pressure auxiliary brake resistance；Tradition behaviour
Vertical pole bar length is shorter, and pedal force is big during brake, and the corresponding pedal of brake effective travel tramples that amplitude is big, and braking efficiency is not high；Limit
The position spring-loaded boss of peace is relatively narrow, is easily subjected to displacement or even comes off, installation limiting is unreliable.
Invention content
Technical problem to be solved in the utility model, which is to provide one kind, can improve positive braking stroke, installation limiting
Reliably, the automobile vacuum booster control stick of Labor-saving high-efficiency.
The automobile vacuum booster control stick of the utility model, including the body of rod, body of rod one end is connected to oil pump piston, separately
One end is connected to brake pedal, it is characterised in that：The body of rod has bulb with oil pump piston connecting pin；Body of rod stage casing is provided with limiting
Boss, the circular ring shape limit ribs of protrusion are provided on positive stop lug boss supporting surface, and positive stop lug boss width dimensions are more than conventional manipulate
The projection width size of bar；
The limit ribs height dimension is slightly larger than respective springs diameter；
A plurality of concentric circles annular limit ribs are provided on the positive stop lug boss supporting surface；
The spiral shape limit ribs extended from center to inverted position turn are provided on the positive stop lug boss supporting surface；
The limit ribs sectional dimension is right angled triangle, and the long side of right angled triangle is overlapped with supporting surface, and short side hangs down
Directly in supporting surface；
The body of rod is taper with bulb linkage section；
The bulb diameter is more than the diameter of the body of rod and bulb link position；
The Bulb Surface has plane, and planar diameter is not more than 2.5mm；
The body of rod length is more than conventional lever length dimension.
The automobile vacuum booster control stick of the utility model, body of rod length is more than conventional lever length, similary
Pedal force and trample under amplitude conditions, can increase effective travel, improve braking efficiency；Positive stop lug boss is by limit ribs
Spring provides limiting, improves limiting unfailing performance, mechanism stable connection.
Description of the drawings
Fig. 1 is the automobile vacuum booster control stick planar structure schematic diagram of the utility model embodiment；
Fig. 2 is the close-up schematic view of Fig. 1.
Specific embodiment
As shown in the figure, a kind of automobile vacuum booster control stick, including the body of rod 1,1 one end of the body of rod is connected to oil pump work
Plug, the other end are connected to brake pedal, and the body of rod 1 has bulb 3 with oil pump piston connecting pin, is connected by bulb 3 and bindiny mechanism
Connect composition universal ball structure；1 stage casing of the body of rod is provided with positive stop lug boss 2, and positive stop lug boss provides axial limit for the spring of installing mechanism
Position；The circular ring shape limit ribs 4 of protrusion are provided on 2 supporting surface of positive stop lug boss, limit ribs 4 are provided for spring and radially limited；
2 width dimensions of positive stop lug boss are more than the projection width size of conventional lever, can improve limiting unfailing performance；Limit ribs 4
Height dimension is slightly larger than respective springs diameter, radially limits reliable.
A plurality of concentric circles annular limit ribs 4 are provided on 2 supporting surface of positive stop lug boss, can adapt to the bullet of different circle diameters
Spring.
The spiral shape limit ribs extended from center to inverted position turn are provided on 2 supporting surface of positive stop lug boss, can adapt to bullet
The reducer of spring end.
4 sectional dimension of limit ribs is right angled triangle, and the long side of right angled triangle overlaps with supporting surface, short side perpendicular to
Supporting surface is provided for spring by the short side vertical with supporting surface and radially limited, will not displacement.
The body of rod 1 is taper with 3 linkage section of bulb, easy to connect.
3 diameter of bulb is more than the diameter of the body of rod 1 and 3 link position of bulb, and bulb can be by corresponding on mounting structure
Cavity is mounted.
3 end face of bulb has plane, and planar diameter is not more than 2.5mm, and installation operation is convenient.
1 length of the body of rod is more than conventional lever length dimension, can increase effective travel, improves braking efficiency.
The automobile vacuum booster control stick of the utility model, body of rod length is more than conventional lever length, similary
Pedal force and trample under amplitude conditions, can increase effective travel, improve braking efficiency；Positive stop lug boss is by limit ribs
Spring provides limiting, improves limiting unfailing performance, mechanism stable connection.
The rod body material is 699 45K of GB/T.
