The specific embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Same member in description and accompanying drawing is to represent with same symbol, no longer repeat specification.And explanation is during the utility model, if the utility model aim is thickened to illustrating of relevant known function or structure, omits this explanation.The numeral of using in the declarative procedure of this specification sheets (as first, second etc.) belong to a kind of distinguishing mark, for the differentiation of a member and another member.
Below in conjunction with accompanying drawing, brake equipment of the present utility model is described in detail.
Fig. 1 is the schematic diagram of the brake equipment of an embodiment of the utility model.
As shown in the figure, the brake equipment of an embodiment of the utility model can provide with driver the brake pedal 11 corresponding treadle effort of exerting pressure.
In the middle of vehicle operating, user can exert pressure to brake pedal 11 with pin.
Brake pedal 11 is applied in pressure, and brake motor 17 can rotation.
Brake motor 17 rotates ball screw 19 plane of revolutions advances piston 21.Piston 21 advances pressure occurs, and makes wheel cylinder generate braking and presses and realize and braking.
Brake pedal 11 is applied in pedal simulator 13,15,23 operations of pressure.Pedal simulator 13,15,23rd, to the device of the constant treadle effort of brake pedal 11 feedback.With the braking of conventional hydraulic formula running, be that pressure by hydraulic pressure itself applies treadle effort to brake pedal 11.But the brake-by-wire device that inserts electric controller is to increase pedal simulator 13,15,23, to feed back treadle efforts to brake pedal 11.
Pedal simulator 13,15,23 comprise the first simulator electromagnetic valve 13 and the second simulator electromagnetic valve 15, counter-force device 23.
The first simulator electromagnetic valve 13 in open state, converts (close) state of closing to when flat after brake pedal 11 is applied in pressure.The second simulator electromagnetic valve 15 is at ordinary times in closing (close) state, but brake pedal 11 converts open (open) state while being applied in pressure to.
The second simulator electromagnetic valve 15 can be transmitted to counter-force device 23 by hydraulic pressure after open.Counter-force device 23 can support brake pedal 11.After counter-force device 23 is applied in hydraulic pressure, counter-force device 23 can be exerted pressure to brake pedal 11.Brake pedal 11 is exerted pressure by counter-force device 23, is stepping on the chaufeur of brake pedal 11 and can experience constant antagonistic force from brake pedal 11.Therefore user can obtain suitable feedback by antagonistic force size.
The stream being connected with the second simulator electromagnetic valve 15 can be connected in treadle effort changeable device 31,33,35,37.In other words, treadle effort changeable device 31,33,35,37 means that the second simulator electromagnetic valve 15 is in the lower running of open state (open).
Treadle effort changeable device 31,33,35,37th, according to the treadle effort of the operation mode change brake pedal 11 of vehicle.For example, vehicle is configured to soft mode formula, and treadle effort changeable device 31,33, and 35,37 meetings are the treadle effort of adjustable brake pedal 11 mildly, and be configured to mode of motion and represent to regulate more massively treadle effort, and then the body sense quality of lifting vehicle chaufeur.
Treadle effort changeable device 31,33,35,37 comprises first device 31,33 and the second device 35,37.The device quantity that treadle effort changeable device 31,33,35,37 comprises can have numerous variations.
First device 31,33 comprises that the first electromagnetic valve 31 and the first Room 33, the second devices 35,37 comprise the second electromagnetic valve 35 and the second Room 37.
First and second chamber 33,37 can have different elastic force mutually.For example, the elasticity of the first Room 33 is K1, and the elastic force of the second Room 35 is K2.
Control part is from first and second device 31,33, at least to select one to implement to activate according to the current operation mode of vehicle.In other words the hydraulic pressure strength that, is transmitted to counter-force device 23 according to the specific device being activated can change.For example, activate on the elastic force of 31,33 counter-force device of first device 23 own and also can add the elastic force of the first Room 33.Therefore the pedal intensity of force that chaufeur is experienced by brake pedal 11 can change.If first device 31,33 and the second device 35,37 are all activated to the pedal intensity of force that chaufeur is experienced by brake pedal 11 and can reappear variation.
Fig. 2 is the diagram of pictorial image 1 first and second electromagnetic valve running action.
As shown in the figure, control part is that first and second is installed to the change treadle effort that suitably combines.In other words, the function of first and second device is all stopped, the treadle effort of transmission plate application force device 23, from first and second device, only activate one of them, by the device activating and the antagonistic force transmission added together of antagonistic force 23, or first and second device is all activated first and second device activating and the antagonistic force transmission added together of counter-force device 23.。
Thereupon, adjust the antagonistic force that chaufeur is experienced by brake pedal 11, make it the corresponding and perceived quality that lifting chaufeur is experienced of driving model with vehicle.
Above embodiment and particular terms only, in order to the technical solution of the utility model to be described, are not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in aforementioned each embodiment, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of technical scheme described in each embodiment of the utility model.
