Further, the second end 23b of motor push rod 23 is equipped with the second installation protrusion 231, the other end of the first elastic component 3
Housing is fixed on the periphery wall of the second installation protrusion 231.For example, as shown in Figure 1 and Figure 4, the second installation protrusion 231 towards the
One installation protrusion 121 is extended, and the second installation protrusion 231 can be coaxially disposed with the first installation protrusion 121, the first elastic component

Device 100 is in initial position, at this time at the time of the state and start-up operation of the first elastic component 3, the state of the second elastic component 4 and opens
It can be arranged according to actual needs at the time of beginning work.For example, when pedal sense simulator 100 is in initial position, the first elasticity
Part 3 and the second elastic component 4 are that pre-compressed state, i.e. the first elastic component 3 and the second elastic component 4 are in compressive state to electricity
Machine push rod 23 generates active force；When driver's pushes pedals 101, the first elastic component 3 and the second elastic component 4 are worked at the same time.Or
Person, when pedal sense simulator 100 is in initial position, the first elastic component 3 is pre-compressed state and the second elastic component 4 is nature
State, the first elastic component 3 generates active force to motor push rod 23 at this time, the second elastic component 4 does not generate effect to motor push rod 23
Power mutually only can support or be spaced setting between one end of the second elastic component 4 and corresponding motor push rod 23 or electric motor primary 21
It sets；When pedal sense simulator 100 is in one end of initial position and the second elastic component 4 and corresponding motor push rod 23 or motor
When mutually only supporting between primary 21, driver's pushes pedals 101, the displacement of pedal 101 is greater than zero, then the first elastic component 3 and the

When being spaced setting between the motor push rod 23 or electric motor primary 21 answered, the displacement of pedal 101 reaches its setting value or motor pushes away
After the displacement of bar 23 reaches its setting value, the first elastic component 3 and the second elastic component 4 are just worked at the same time, and the displacement of pedal 101
When the amount not up to displacement of its setting value or motor push rod 23 is not up to its setting value, the work of only the first elastic component 3.Again
For example, the first elastic component 3 and the second elastic component 4 are nature, at this time when pedal sense simulator 100 is in initial position
First elastic component 3 and the second elastic component 4 do not apply elastic force to motor push rod 23, and the both ends of the first elastic component 3 can be divided
Inner wall not with the second end 23b of motor push rod 23, shell 1 mutually only supports, one end of the second elastic component 4 can in shell 1
Wall mutually only supports, the other end only can support or be spaced setting with the second end 23b phase of motor push rod 23.But not limited to this.
Optionally, as shown in Figure 1 and Figure 4, the second installation protrusion 231 is fixed on motor by mounting screw 232 and pushes away
