To optimize the above problem, some simulators add rubber shock-absorbing spring, rubber bullet on the basis of said structure
Spring has compressed capability outstanding, can make up helical spring and compress hypodynamic weakness, so that structural volume is reduced, and rubber bullet
The rigidity of spring has certain nonlinear characteristic, can be with the effect of partial simulation power sluggishness.But rubber spring rigidity by environment because
Element has a great influence, and especially at low ambient temperatures, restoring force can be deteriorated, and influences overall pedal sense, and the characteristic of rubber spring
Debugging is more difficult.
In general, current pedal force simulator does not design power bradytoia life structure, its pedal sense is helped with sensing
Power device difference is obvious；Though the strong stagnant sensor having, complicated, piece volumes are big, and cost benefit is poor.

Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained on the premise of creative work is not made, all belong to
In the scope of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of brake pedal force simulator with the stagnant structure of power, it includes a housing 1,
Groups of springs 2, support base 3, friction component, jacking block 5, end cap 6 and push rod 7 are accommodated in the housing 1 successively.
One end of the push rod 7 is provided with the shift fork for being articulated with brake pedal arm or bulb, the bulb of other end setting with being somebody's turn to do
The spherical groove opened up on jacking block 5 is hinged.Brake pedal arm can head on push rod 7, then push rod 7 during rotary motion
Jacking block 5 is headed on to axially move in piston.
As shown in Fig. 2, be fixed with connecting key 51 on the end face of the jacking block 5, on the end face of the jacking block 5 and it is located at the connecting key
51 both sides offer arc tapered plane 52 respectively, and two arc tapered planes 52 are relative to the substantially symmetrical about its central axis (see figure of the jacking block 5
2 and 3).
The friction component includes at least two brake pads 4, which is fan-shaped column, and the end face of the brake pad 4 is
Conducting bar 42 is offered in inclined plane 41, other end, the inclined plane 41 is against the arc tapered plane 52, one end of the support base 3
Face is fixed with keyway 31, and line slideway 32 is respectively fixed with the end face of the support base 3 and positioned at the both sides of the keyway 31, should
Line slideway 32 is corresponded with the brake pad 4, which is slidably connected with corresponding line slideway 32, and the connecting key 51 is solid
Due in the keyway 31, the other end of the support base 3 is provided with positioning convex platform, and the positioning is fixed in one end of the groups of springs 2
Boss, the other end are resisted against the bottom of the housing 1.
Circular hole is offered on the end cap 6, which is sheathed on the push rod 7 by the circular hole, and the end cap 6 is covered on
On the housing 1.
Pedal force forms：F1 small spring forces, F2 high spring forces, f frictional force, push rod are made a concerted effort F.When stepping on braking：F steps on=F1+
F2+f；During pine braking：F pines=F1+F2-f.F steps on-F pines=2f.Due to the presence of frictional force, when stepping on braking and pine braking, pedal
Had differences between power, this species diversity can simulate the pedal sense that traditional booster produces.
During jacking block 5 promotes 4 axial-movement of brake pad, arc tapered plane 52 can the 4 corresponding inclination of extrusion friction block
Face 41.Connection strong 51 is corresponding with 31 shape of keyway, ensures that the rotation around axis direction will not be produced between jacking block 5 and support base 3
Transhipment is dynamic.Brake pedal arm can head on push rod 7 during rotary motion, and then push rod 7 heads on work of the jacking block 5 in housing 1
Axially moved in plug.The effect of 5 drawn stem 7 of jacking block and housing power, produces along 1 axial-movement of housing, passes through arc tapered plane
52 movements are delivered to brake pad 4, and produce one perpendicular to the component of axis direction and a component in the axial direction.
Under the action of axial direction component, the inner wall of brake pad 4 and shell 1 produces mutually extruding.Due to brake pad 4 and shell
1 inner wall is designed with certain friction coefficient, and the interaction force between them can produce an axis direction, along shell 1
The frictional force of inner wall distribution.Component in the axial direction then continues to be delivered to support base 3, finally causes the axial pressure of groups of springs 2
Contracting.The two component and 7 thrust proportion relation of push rod, the size of ratio is by adjusting the angle of arcuation tapered plane and rubbing
Coefficient is wiped to obtain.Piston in the other end promotion master cylinder of support base 3 for braking in emergency circumstances, is braked forward
Structure in master cylinder does not embody in this patent description.Conducting bar 42 on these 32 friction fit elements of line slideway, ensures to rub
When cleaning block 4 is squeezed, along specified direction and the interior wall friction of housing 1.
The lower end of support base 3 is equipped with two groups of springs with the low side of housing 1.Since traditional booster stress curve approximation can be with
It is divided into two sections of power-assisteds, initial one section of power-assisted slope is smaller, and second segment power-assisted slope is bigger than normal.For the pedal sense of the traditional booster of simulation
Feel：Front half section pedal force is provided by little spring, and second half section support base is contacted with big spring, produces second segment power.
