Description

The brake pedal system that a kind of predetermincd tension is adjustable
Technical field
The present invention relates to a kind of brake pedal, more particularly, relate to the brake pedal system that a kind of predetermincd tension is adjustable.
Background technology
Along with the development of science and technology, improving constantly of national life level, the vehicle make rapid progress, and traffic safety problem also more and more obtains the concern of people.Automobile is one of main vehicle, and increasing automobile uses automatic transmission with hydraulic torque converter at present.Automatic transmission with hydraulic torque converter owing to no longer needing manual shfit, so eliminate pedal of clutch, only remaining throttle and brake pedal.And throttle, brake that at present vehicle uses are all adopt right crus of diaphragm to control, during normal traveling, generally use right crus of diaphragm step on the accelerator, when finding that there is abnormal condition and needing emergency brake, need to lift right crus of diaphragm, make right crus of diaphragm be separated with Das Gaspedal and shift to brake pedal, firmly step on and just start brake gear, car is stopped.But in case of emergency, navigating mate is overstretched, especially for new navigating mate, easily make mistakes in chaos, once occur that mistaking accelerator for brake is stepped on, and do not have power-transfer clutch to disconnect the power of driving engine, cause vehicle not only can not stop, front can be rushed at quickly on the contrary, thus cause more serious accident.
How better to avoid the generation of this kind of accident, have the research of this respect and corresponding anti-false step on device both at home and abroad, as throttle brake link gear, throttle brake device, device for controlling mis-step on accelerator of vehicle, automobile accelerator stepping misoperation preventing emergency braking apparatus etc.But also there is following problem and defect in these design and researchps: one is need to have carried out a lot of transformation to existing body construction; Two is that cost is high, and cost performance is low, is unfavorable for promoting.
Retrieve through Chinese patent, Chinese Patent Application No. 201110149580.7, Shen Qing Publication day is on April 25th, 2012, invention and created name is: device for preventing mistaken pedaling of accelerator pedal, this application case relates to a kind of device for preventing mistaken pedaling of accelerator pedal, outside the normal accelerating travel of Das Gaspedal, increase a stroke, and between Das Gaspedal and brake pedal, a linkage is installed, the stroke coordinated signals brake pedal utilizing Das Gaspedal to increase.This application case can also initiatively be braked when chaufeur mistake is stepped on Das Gaspedal as brake pedal in fast automatic identification, the generation of minimizing accident, and does not affect driving habit, does not also affect the various functions of automobile.But the occupation mode of this application case is when chaufeur in case of emergency step on Das Gaspedal as brake pedal by mistake, react by instinct, can step down by a pin with strength, moment floors Das Gaspedal, now throttle swing arm drives brake swing arm fast brake pedal to be pressed onto the end, parking of stopping; But run in reality emergency situation might not be need touch on the brake, be also likely need step on the accelerator to accelerate, in this case, if Das Gaspedal is floored by chaufeur can cause even more serious consequence due to vehicle all standing on the contrary.
