Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
As shown in Figs. 1-2, the embodiment of the utility model is related to a kind of simulation of adjustable automobiles brake pedal feel
Device, including master cylinder 2 and pedal 3, the piston inside the master cylinder 2 is connected with the pedal 3 of its one end, described
First chamber connects reversal valve 4 and return valve 15, the reversal valve 4 and return valve respectively by pipeline 14 in master cylinder 2
15 are connected by pipeline 14 with pedal simulator 5, and the pedal simulator 5 includes emulator piston 6 and spring end cap 13,
The first spring 12 is axially installed with inside the spring end cap 13, the inside of the spring end cap 13 is provided with and the first bullet
The sliding inner sleeve 10 that one end of spring 12 is withstood, side wall is close to inside the sliding inner sleeve 10 and is provided with second spring 11 and slides
The internal end surface of inner sleeve 10 is provided with bolster 9 between two parties, and axial one end of the second spring 11 is connected with end sliding sleeve
7, one end of the emulator piston 6 is connected with end sliding sleeve 7, and the reversal valve 4 is also held by pipeline 14 and oil storage
Device 1 is connected, and the left and right chamber in the master cylinder 2 is connected with oil vessel 1.
The reversal valve 4 is two-position-five-way solenoid valve, and the A mouths of the reversal valve 4 are connected with master cylinder 2, P mouthfuls and pedal
Simulator 5 is connected, and T mouthfuls are connected by pipeline 14 with oil vessel 1, and two-position-five-way solenoid valve is common solenoid directional control valve.
The end sliding sleeve 7 and sliding inner sleeve 10 is U-shaped cap-like structure, convenient to compress spring, is also convenient for axial direction
It is mobile.
Between two parties axially across being disposed with lead 8 between the end sliding sleeve 7 and sliding inner sleeve 10, the lead 8
Passed through from the middle part of bolster 9, guiding role can be played, improve the effect of simulation.
As a kind of embodiment and operation principle of the utility model, as shown in Figure 1, pedal attonity, reversal valve 4 is in
