The present invention proposes the attachment means of a kind of brake pedal and vacuum booster, including vacuum booster connecting rod and pedal linking arm, the pedal linking arm is connected with vacuum booster connecting rod by a connecting shaft, the connecting shaft is variable cross-section hollow shaft, and a crushed portion is provided with along tube wall inner side, the pipe thickness of the crushed portion is less than connecting shaft pipe thickness.The connecting shaft is designed using variable cross section-type; when vehicle collides; impact force is delivered in connecting shaft by vacuum booster connecting rod; connecting shaft is subject to be broken at crushed portion from variable cross-section during larger shearing force; prevent impact force from continuing to be delivered to driver leg; so as to protect driver leg, the crumple requirement of brake pedal is met.
Description
Technical field
The invention belongs to brake system of car technical field, the connection of more particularly to a kind of brake pedal and vacuum booster
Device.
Background technology
At present, brake pedal arm and vacuum booster push rod be generally it is coaxial be directly connected to, driver's brake pedal,
Pedal arm rotates around pedal shaft, pushes directly on vacuum booster push rod, realizes the transmission of pedal force.Brake pedal is fixed on
In front panel, when automobile occurs head-on crash, the impulsive force of collision passes to brake pedal by vacuum booster push rod, braking
Crumple mechanism on pedal will occur crumple, so as to reduce the shock strength of driver's ankle and shank and brake pedal, have
Effect reduces injury of the brake pedal to the leg of driver, is effectively protected the safety of driver.
When the pedal arm of brake pedal is influenceed not coaxial with vacuum booster push rod because of arrangement problem or by lever ratio
When, it is necessary to increase by an attachment means between the two, to avoid the original crumple mechanism of brake pedal different because of stress point, and cannot
Its crumple performance is realized in collision process, causes the impulsive force of collision to be delivered to driving by vacuum booster and brake pedal
Member foot, causes human pilot leg injury.
In sum, for pedal arm and booster push rod out-of-alignment situation, it is necessary to design new crumple mechanism, make
Brake pedal can reduce the injury to human pilot leg in collision.
The content of the invention
In view of this, the present invention is directed to propose the attachment means of a kind of brake pedal and vacuum booster, using variable cross-section
The crumple requirement of brake pedal during collision is realized in formula design, simple structure, is easily achieved, and is used while intensity requirement is met
Hollow design, realizes lightweight.
To achieve the above object, the present invention provides the attachment means of a kind of brake pedal and vacuum booster, including vacuum
Booster connecting rod and pedal linking arm, the pedal linking arm are connected with vacuum booster connecting rod by a connecting shaft, the company
Spindle is variable cross-section hollow shaft, and is provided with a crushed portion along tube wall inner side, and the pipe thickness of the crushed portion is less than connecting shaft tube wall
Thickness.
Further, the connecting shaft has the second end of first end and extension relative with the first end, the pedal linking arm
One end is provided with a fixing hole, and connecting shaft first end is connected through the fixing hole with pedal linking arm, and pedal linking arm is connected to system
Dynamic pedal.
Further, the end of connecting shaft second is connected with vacuum booster connecting rod, and vacuum booster connecting rod is provided with
One mounting hole is used to be connected with vacuum booster.
Further, a steady pin is equiped with the connecting shaft two ends mouth of pipe, is consolidated connecting shaft by the steady pin
It is scheduled on clutch pedal mounting bracket.
The connecting shaft is designed using variable cross section-type, and when vehicle collides, impact force passes through vacuum booster connecting rod
Be delivered in connecting shaft, connecting shaft be subject to larger shearing force when from variable cross-section crushed portion fracture, prevent impact force from after
Resume and be delivered to driver leg, so as to protect driver leg, meet the crumple requirement of brake pedal.
Brief description of the drawings
Fig. 1 is the brake pedal of the embodiment of the present invention and the structural representation of the attachment means of vacuum booster.
Fig. 2 is the brake pedal of the embodiment of the present invention and the partial sectional schematic view of the attachment means of vacuum booster.
Specific embodiment
Further to illustrate the present invention to reach technological means and effect that predetermined goal of the invention is used, below in conjunction with
Accompanying drawing and preferred embodiment, to specific embodiment of the invention, structure, feature and its effect, describe in detail as after.
As shown in Figures 1 and 2, a kind of connection of the attachment means of brake pedal and vacuum booster, including vacuum booster
Bar 11 and pedal linking arm 12, pedal linking arm 12 are connected with vacuum booster connecting rod 11 by a connecting shaft 13, connecting shaft
13 is hollow shaft, probably diminishes to form crushed portion 131 in the centre position section of connecting shaft 13, and crushed portion 131 is from connecting shaft 13
Inwall peripheral indentation one week formed, the pipe thickness of the pipe thickness less than connecting shaft 13 of crushed portion 131, it is ensured that connecting shaft
13 are broken in collision herein, meet crumple requirement.In addition, the length of connecting shaft 13 and brake pedal and vacuum booster
Position is relevant.
The one end of pedal linking arm 12 is provided with a fixing hole 121, and connecting shaft 13 has first end and extension relative with first end
The second end, the first end of connecting shaft 13 is connected through fixing hole 121 with pedal linking arm 12, and the other end of pedal linking arm 12 connects
It is connected to brake pedal；Second end of connecting shaft 13 is connected with vacuum booster connecting rod 11, and vacuum booster connecting rod 11 is another
End is provided with a mounting hole 111, is connected with vacuum booster push rod (not shown) by mounting hole 111.Specifically, connecting shaft
13 two ends mouth of pipe inner side are equiped with a steady pin 14, and a through hole 141 is offered in the middle of two steady pins 14, are passed through using a bolt logical
Be fixed on connecting shaft 13 on clutch pedal mounting bracket (not shown) by hole 141.
Operationally, driver's brake pedal, pedal force passes to pedal linking arm 12, pedal by brake pedal
Pedal force on linking arm 12 is delivered in vacuum booster connecting rod 11 by connecting shaft 13, is ultimately applied to vacuum servo
Device, realizes braking.
When vehicle collides, impact force is delivered in connecting shaft 13 by vacuum booster connecting rod 11, due to even
Spindle 13 is designed using variable cross section-type, and connecting shaft 13 is subject to that during larger shearing force the i.e. conquassation from variable cross-section of connecting shaft 13 can be made
It is broken at portion 131, prevents impact force from continuing to be delivered to driver leg, so as to protect driver leg, meets brake pedal
Crumple requirement.
Attachment means of the invention, simple structure, are easily achieved, and are braked when realizing vehicle collision using variable cross section-type design
The crumple requirement of pedal, injury when being effectively reduced collision to driver leg, using sky while intensity requirement is met
