Embodiment 1

[0070] In this example, if Figure 1-Figure 7As shown, the pedal feel simulator 100 includes a housing 1 , a linear motor 2 , a first elastic member 3 and a second elastic member 4 .

[0071] The housing 1 includes a main cylinder body 11, a bottom cover 12 and a fixed plate 13. The main cylinder body 11 is roughly formed into a cylindrical structure, the axial ends of the main cylinder body 11 are open, and the bottom cover 12 is arranged on the axial direction at one end (for example, if figure 1 middle lower end), the fixed plate 13 is located at the other axial end of the main cylinder body 11 (for example, as figure 1 The upper end of the middle), so that the bottom cover 12, the main cylinder body 11 and the fixed plate 13 jointly define a closed accommodation space. Specifically, such as Figure 1-Figure 6 As shown, a first connecting portion 111 is formed on the upper end of the main cylinder body 11, and the first connecting portion 111 protrudes outward along the ...

Embodiment 2

[0080] Such as Figure 8 As shown, the structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same components use the same reference numerals, the difference is: when the driver does not step on the pedal 101 and the pedal feeling simulator 100 is in the initial position, the first Both the elastic member 3 and the second elastic member 4 are in a natural state, the two ends of the first elastic member 3 are respectively against the inner wall of the housing 1 and the second end 23b of the motor push rod 23, and the lower end of the second elastic member 4 is in contact with the second end 23b of the motor push rod 23. The inner wall of the housing 1 is in contact with each other, and the upper end of the second elastic member 4 is spaced apart from the second end 23b of the motor push rod 23 . When the driver steps on the pedal 101, the first elastic member 3 first works to apply an elastic force to the motor push rod 23. When the displace...

Abstract

The invention discloses a pedal-feeling simulator for a vehicle and the vehicle with the pedal-feeling simulator. The vehicle comprises a pedal, and the pedal-feeling simulator comprises a shell, a linear motor, a first elastic part and a second electric part; and the linear motor comprises a motor primary part, a motor secondary part and a motor push rod, the motor secondary part is matched withthe motor primary part so that the motor secondary part can axially move relative to the motor primary part, the motor secondary part drives the motor push rod to move synchronously, the first end ofthe motor push rod extends out of the shell to be suitable for being connected with the pedal, the two ends of the first elastic part are matched with the inner wall of the shell and the second end ofthe motor push rod correspondingly, the second elastic part and the first elastic part are located on the two axial sides of the motor primary part, and the two ends of the second elastic part are matched with the motor pushing rod and the motor primary part. The pedal-feeling simulator for the vehicle is high in response speed, has the good braking effect, and meanwhile can provide the good 'braking feeling', especially a pedal braking feeling, for a driver.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a pedal feeling simulator for a vehicle and a vehicle with the same. Background technique [0002] In the related art, the pedals in the vehicle mainly use a hydraulic transmission mechanism or a pneumatic transmission mechanism for power transmission, so as to realize braking of the vehicle. However, the response speed of the brake system adopting the hydraulic transmission mechanism or the pneumatic transmission mechanism is relatively slow, and the braking performance is poor, which brings great inconvenience to the actual operation of the driver. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a kind of pedal feel simulator that is used for vehicle, and described pedal feel simulator has fast response speed, has good braking effect, can ...
