Problems solved by technology

[0002] At present, in the field of automobile braking, with the gradual development of electronically controlled braking systems, the direction of technology research and development has developed to the wire-controlled hydraulic braking system. The pedal feeling is derived from the pedal feeling simulator, which uses the damping of the piston of the pedal feeling simulator to provide pedal feedback feeling, but this structure cannot adjust the relationship curve between the force F of the pedal feel and the pedal stroke x, resulting in the inability to adjust the braking system. Adjustment, resulting in the inability to switch the sense of braking, affecting the use of the braking system

Embodiment Construction

[0012] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0013] Such as figure 1 As shown, the present embodiment provides a pedal stroke simulator device, including an input pedal 1, a pedal cylinder 2, a pedal stroke sensor 3 and a pedal stroke simulator 4, wherein the input pedal 1 is connected to the pedal cylinder 2 The pedal stroke sensor 3 is installed on the pedal cylinder 2, the pedal stroke simulator 4 is connected with the pedal cylinder 2 through a normally closed linear valve 5, and the normally closed linear valve 5 regulates and controls two end pressure difference. The normally closed linear valve 5 is provided with a liquid return one-way valve 6 , and the conduction direction of the liquid return one-way valve 6 is from the p...

Abstract

The invention provides a pedal stroke simulator device which comprises an input pedal, a pedal cylinder, a pedal stroke sensor and a pedal stroke simulator. The pedal stroke simulator device is characterized in that the input pedal is connected to a piston rod of the pedal cylinder, the pedal stroke sensor is mounted on the pedal cylinder, the pedal stroke simulator and the pedal cylinder are connected through a normally closed linear valve, and the normally closed linear valve adjusts and controls the pressure difference of the two ends through electromagnetic force. Through cooperation of the input pedal, the pedal cylinder, the pedal stroke sensor and the pedal stroke simulator, pedal sense simulation work during foot-step braking is completed, the pressure difference of the two ends ofthe pedal cylinder and the pedal stroke simulator are controlled through the normally closed linear valve, then the relation curve between the force F of pedal sense and the pedal stroke x is adjusted, thus linear change selection of a braking system is increased, and the use sense of a user is improved.

Description

technical field [0001] The invention relates to the field of automobile brake control, in particular to a pedal stroke simulator device. Background technique [0002] At present, in the field of automobile braking, with the gradual development of electronically controlled braking systems, the direction of technology research and development has developed to the wire-controlled hydraulic braking system. The pedal feeling is derived from the pedal feeling simulator, which uses the damping of the piston of the pedal feeling simulator to provide pedal feedback feeling, but this structure cannot adjust the relationship curve between the force F of the pedal feel and the pedal stroke x, resulting in the inability to adjust the braking system. Adjustment, resulting in the inability to switch the sense of braking, affecting the use of the braking system. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a pe...
