Problems solved by technology
Among them, the non-decoupling solution can feed back the change of brake fluid pressure to the brake pedal through the mechanical structure, which is the same as the pedal feeling principle of the vacuum booster. Under functions such as ABS braking, it will also cause changes in the brake pedal force, resulting in poor pedal feel

Embodiment Construction
[0081] Such as figure 1 As shown, the present invention provides an embodiment of a force simulator for simulating vehicle pedal feedback, including: a sealed housing 1, first to third elastic members 2-4 and first to third transmission members 5-7;
[0082] The first elastic member 2 is fixed on the side wall of the sealed housing 1, the second elastic member 3 is sleeved on the outside of the first elastic member 2, and the first transmission member 5 is arranged between the second elastic member 3 and the second elastic member 3. Between the three elastic members 4, part of the third elastic member 4 penetrates into the second elastic member 3, and one end of the second transmission member 6 passes through the third elastic member 4 and passes through the first transmission member 5 and is inserted into the second elastic member 5. In the elastic member 3, the other end of the second transmission member 6 is fixed on the third transmission member 7, and the sealed housing ...

The invention discloses a force simulator. A first elastic piece is fixed on one side wall of a sealing shell, a second elastic piece sleeves the outer side of the first elastic piece, a first transmission piece is arranged between the second elastic piece and a third elastic piece, part of the third elastic piece penetrates into the second elastic piece, one end of the second transmission piece penetrates through the third elastic piece and penetrates out of the first transmission piece to be inserted into the second elastic piece, the other end of the second transmission piece is fixed to athird transmission piece, the sealing shell is divided into a first sealing cavity and a second sealing cavity through the third transmission piece, the space of the first sealing cavity and the spaceof the second sealing cavity can be dynamically changed, a first port of the force simulator is formed in one side wall of the first sealing cavity, and a second port of the force simulator is formedin one side wall of the second sealing cavity. The invention further discloses an electronic hydraulic braking system with the force simulator. The force simulator is very suitable for simulating vehicle pedal feedback force, and is also suitable for simulating other mechanical stress feedback in other fields.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a force simulator for simulating pedal feedback. The invention also relates to an electrohydraulic braking system with such a force simulator. Background technique [0002] The braking system is a vital system related to the safety performance of the vehicle, and its performance will directly affect the driving safety performance of the vehicle. A traditional braking system usually consists of a brake pedal, vacuum booster, brake master cylinder, ESC / ABS, brake wheel cylinder and its corresponding pipelines. The whole system is relatively complex, and is at a disadvantage in volume, quality and integration. Moreover, the vacuum of the vacuum booster comes from the automobile engine. With the gradual popularization of electric vehicles, the source of vacuum has become a problem. At present, most vehicles use an additional vacuum pump to provide the vacuum. However, this solution is o...
