Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As shown in Figure 1-2, embodiments of the present invention are related to a kind of analogue means of adjustable automobiles brake pedal feel,
Including master cylinder 2 and pedal 3, the piston inside described master cylinder 2 is connected with the pedal 3 of its one end, described braking
First chamber connects reversal valve 4 and return valve 15 respectively by pipeline 14 in master cylinder 2, and described reversal valve 4 and return valve 15 are equal
It is connected by pipeline 14 with pedal simulator 5, described pedal simulator 5 includes emulator piston 6 and spring end cap 13, described
Spring end cap 13 inside be axially installed with the first spring 12, the inside of described spring end cap 13 is provided with and the first spring 12
The sliding inner sleeve 10 that withstands of one end, be close to side wall inside described sliding inner sleeve 10 and second spring 11 and sliding inner sleeve be installed
10 internal end surface is provided with bolster 9 between two parties, and axial one end of described second spring 11 is connected with end slip cap 7, institute
The one end for the emulator piston 6 stated is connected with end slip cap 7, and described reversal valve 4 also passes through pipeline 14 and the phase of oil vessel 1
Even, the left and right chamber in described master cylinder 2 is connected with oil vessel 1.
Described 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 mouths and pedal
Simulator 5 is connected, and T mouths are connected by pipeline 14 with oil vessel 1, and two-position-five-way solenoid valve is conventional solenoid directional control valve.
Described end slip cap 7 and sliding inner sleeve 10 is U-shaped cap-like structure, facilitates compression spring, is also convenient for axial direction
It is mobile.
Between two parties axially across being disposed with lead 8 between described end slip cap 7 and sliding inner sleeve 10, the lead 8
Passed through from the middle part of bolster 9, guide effect can be played, improve the effect of simulation.
As a kind of embodiment and operation principle of the present invention, as shown in figure 1, pedal attonity, reversal valve 4 is in left position
And be closed, this analogue means is in off working state.
