Embodiment 1

[0067] 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 .

[0068] The housing 1 includes a main cylinder block 11 , a bottom cover 12 and a fixing plate 13 . The main cylinder block 11 is roughly formed into a cylindrical structure. Both ends of the main cylinder block 11 in the axial direction are open. one end (for example, as figure 1 The lower end in the middle), the fixing plate 13 is provided at the other axial end of the master cylinder 11 (for example, as figure 1 The upper end of the middle), so that the bottom cover 12, the main cylinder 11 and the fixing plate 13 together define a closed accommodating space. Specifically, as Figure 1-Figure 6 As shown, the upper end of the master cylinder block 11 is formed with a first connecting portion 111, the first connecting portion 111 is formed to protrude outward along the radial direction of the...

Embodiment 2

[0077] like Figure 8 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, and the same components are given the same reference numerals, the difference is that: when the driver does not step on the pedal 101 and the pedal feel 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 abutted 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 The inner wall of the housing 1 abuts against each other, and the upper end of the second elastic member 4 is spaced apart from the second end 23 b 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 displacement of the pedal 101 reaches its set value, or the...

Abstract

The invention discloses a pedal feel simulator for a vehicle and a vehicle having the same. The vehicle includes a pedal, the pedal feel simulator includes a casing, a linear motor, a first elastic member and a second elastic member, and the linear motor includes a motor primary, The motor secondary and the motor push rod, the motor secondary cooperates with the motor primary so that the motor secondary can move axially relative to the motor primary, the motor secondary drives the motor push rod to move synchronously, and the first end of the motor push rod protrudes out of the casing to fit It is 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 of the motor push rod respectively; the second elastic part and the first elastic part are located on both sides of the primary axial direction of the motor, and the The two ends are fitted on the motor push rod and the motor primary respectively. According to the pedal feeling simulator for vehicles of the present invention, the response speed is fast, the braking effect is good, and at the same time, the driver can be provided with good "braking feeling", especially pedal braking feeling.

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 ...
