The present invention relates to automobile brakes to feel simulator field, is that one kind can switch three kinds of different brake feels
Simulator.
Background technique
For new-energy automobile, to meet energy conservation and environmental protection, the requirement of continuation of the journey is improved, braking energy is carried out using motor
Recycling.In regeneration brake system, due to the participation of regenerative braking moment, so that tradition machinery braking moment and hydraulic braking force
The distribution of square is with regard to particularly important.For vehicle when low speed is braked, braking strategy is the often large scale so that more energy is recycled
It introduces motor reversal bring regeneration torque and participates in braking.In this case, feel brought by tradition machinery hydraulic braking is anti-
Feedback, which just substantially reduces, to be even disappeared completely.A kind of device that can simulate traditional pedal resistance is thus needed, driver is improved and mentions
For the judgement of better vehicle control.
Traditional pedal resistance simulator only only one gear, can only simulate a kind of pedal sense of tightness
Feel, total system solidification is difficult to adjust, and is difficult to adapt to demand of the different drivers to manipulation sense, and if applying to different automobile types
On, it needs to invent whole system parameter again.
Summary of the invention

Oil circuit disconnects, and Pressure Increasing Oil-Line is connected；By turning down adjustable throttle valve, pressure cabin flow is limited, on the basis of nervous pedal force
Reduce pedal resistance；On the basis of nervous pedal force, by opening big adjustable throttle valve, increase pressure cabin flow, further
Increase pedal resistance.
Further, a part of hydraulic oil is pushed into the increasing in pedal simulator by adjustable throttle valve by Pressure Increasing Oil-Line
Ballasting generates additional resistance to the propulsion of the big piston of pedal simulator, thus generates bigger than the offer of normal pedal power
Pedal resistance.
3, beneficial effects of the present invention

Sense, and the resistance of reflux oil circuit can be further adjusted by adjusting throttle valve L, to further adjust pedal resistance.
Thus the present invention can form the pedal resistance sense of three gears, and can on the basis of three gears by throttle valve into
The fine tuning of one step.
(4) present invention can directly control switching gear, nothing by corresponding control circuit due to using electric control reversing valve
Complicated mechanical structure adjustment need to be done, the drive demand of different drivers is easily adapted to.
Detailed description of the invention:
Fig. 1 is off working state schematic diagram of the invention.
Appended drawing reference: A reflux oil vessel, B master cylinder, the first check valve of C, D 2/2-way solenoid directional control valve, E are stepped on
Plate simulator, F booster cavity spring, G resilient snubber, H first throttle valve, I second one-way valve, J 3-position-3-way electromagnetic switch

Specific implementation form:
Embodiment
As shown in Figure 1, pedal k is connected with master cylinder B, equipped with a reflux oil vessel A on master cylinder.Braking master
Cylinder is provided with resilient snubber B, spring F and resilient snubber G is respectively arranged in pedal simulator E, to provide pedal resistance.
Middle section on pedal simulator E equipped with spring is referred to as pressure cabin M, pressure cabin M and adjustable throttle valve H, and three
Position three-way solenoid valve J, master cylinder form pressure-adjusting oil passage.It is big that pressure-adjusting oil passage can control pressure in pressure cabin
It is small, to adjust brake pedal resistance sense.It is obvious that pressure cabin pressure is bigger, pedal resistance sense is bigger.3-position-3-way electromagnetism changes
To valve H, throttle valve L and reflux oil vessel A constitute active oil return circuit, if active oil return circuit is switched on, enter pedal
The oil mass of simulator E will certain amplitude reduce, and then certain amplitude reduce pedal resistance sense.Throttling can further be adjusted
Valve L control reflux resistance, limits regurgitant volume, to further finely tune pedal resistance.2/2-way solenoid directional control valve D is by pedal mould
The main cabin of quasi- device E and master cylinder connect and compose thrust oil circuit.
Check valve C and check valve I forms the independent passive oil return circuit of two-way, after braking stops, in pedal simulator E
Hydraulic oil can be pushed back into master cylinder by passive oil return circuit under the action of spring and resilient snubber, so that braking be made to step on
Sheet reset.
3-position-3-way solenoid directional control valve J, the first check valve C and second one-way valve I form the independent passive oil return of two-way and return
Hydraulic oil can be passed through passive oil return under the action of pedal simulator E spring and resilient snubber after braking stops by road
Circuit pushes back master cylinder, so that brake pedal be made to reset.
As shown in Figure 1, this system, which has, opens and closes two states, " standard " " pine " wherein is adjusted under open state
" tight " three kinds of different pedal pressing force senses.
" standard " (pedal force that can provide 420N or so): 2/2-way solenoid directional control valve D, which powers on, switches to left position,
It connects for 4 mouthfuls to connect thrust oil circuit with 5 mouthfuls.3-position-3-way solenoid directional control valve J continues position in holding, due to 1,2,3 mouthful of guarantor
Closing is held, thus pressure-adjusting oil passage, passive oil return circuit are in unaccessed state.At this point, bullet is fully utilized in pedal pressing force
Spring and resilient snubber are formed by thrust oil circuit.
" pine " (pedal force that can provide 350N or so): 2/2-way solenoid directional control valve D powers on holding and is used as left position,
4 mouthfuls remain up with 5 mouthfuls, and thrust oil circuit keeps clear.3-position-3-way solenoid directional control valve J switches to left position, so that 1 mouthful and 3 mouthfuls
It connects, active oil return circuit is connected.Due to the connection of active oil return circuit, under same pedal rise, the reflux of section hydraulic oil
Hydraulic oil to the oil vessel A that flows back, thus entrance pedal simulator E is reduced, and pedal resistance sense is reduced to a certain degree.?
On the basis of " pine ", regurgitant volume can be increased and reduce reflux resistance by opening big throttle valve, be further reduced pedal resistance (
On the basis of loose state pedal resistance).It can also be by turning down throttle valve, limitation regurgitant volume increases reflux resistance, further increases
Add pedal resistance (on the basis of loose state pedal resistance)
" tight " (can provide the pedal force not higher than 500N): 2/2-way solenoid directional control valve D powers on holding as left
Position, 4 mouthfuls remain up with 5 mouthfuls, and thrust oil circuit keeps clear.3-position-3-way solenoid directional control valve J switches to right position, and 1 mouthful connects with 2 mouthfuls
Logical, 3 mouthfuls of closings cause active oil return circuit to disconnect, and Pressure Increasing Oil-Line is connected.
A part of hydraulic oil is pushed into the middle section pedal simulator E (pressure cabin) by adjustable throttle valve by Pressure Increasing Oil-Line,
Additional resistance is generated to the propulsion of the big piston of pedal simulator E, thus generates the pedal bigger than under " standard " state
Resistance.On the basis of " tight ", it can increase pressure cabin flow by opening big throttle valve, further increase pedal resistance (tight
On the basis of state pedal resistance).Pressure cabin flow can also be limited, reduces pedal resistance (in tight state by turning down throttle valve
On the basis of pedal resistance).
As shown in the table, working condition table:
The present invention, by the adjusting of solenoid directional control valve, forms three based on the resistance that spring and resilient snubber provide
The different pedal resistance of kind is felt, and can further be finely tuned on the basis of three kinds of gears by throttle valve.It easily adapts to not
Driving with driver manipulates demand.
