Abstract
The invention discloses an auxiliary device of a vacuum booster, belonging to the technical field of automobile accessories, and particularly relates to an auxiliary device of a vacuum booster. The auxiliary device comprises a sliding sleeve with a hole on one side wall; a feedback plunger is arranged in the sliding sleeve; a conical ledge is fixed at the front end of the feedback plunger; a hairpin-shaped latch is inserted between the sliding sleeve and the feedback plunger; the latch is arranged at the front end of the conical ledge of the feedback plunger; and a sliding sleeve spring is arranged on the periphery of the sliding sleeve and clamped between the rear end of the sliding sleeve and the latch. The auxiliary device disclosed by the invention can detect the encountered situation in the vehicle driving process according to the speed of the driver stepping on a brake pedal; and if the driver quickly steps on the brake pedal in emergency but the stepping force is not enough, the system increases the brake force to the maximum and keeps the brake force for a period of time in less than 1 second, thereby shortening the brake distance in emergency brake and improving the automobile safety.
Description
Technical field
The invention belongs to the vehicular spare parts technical field, be specifically related to a kind of auxiliary device of vacuum booster.
Background technology
Along with Chinese automobile " universal phase " arrives; Increasing automobile gets into average family; The age level of chaufeur distributes and also becomes more and more wider; Thereby also higher to the requirement of the handling of vehicle and active safety performance, need effective, reliable, a safe braking be provided for chaufeur especially.According to statistics, 90% automobile driver is arranged in case of emergency, it is resolute when touching on the brake, to lack, and active vacuum booster designs to this situation just.
Use the conventional vacuum servo-unit, when the chaufeur that gets deeply stuck in anxiety carries out emergency braking,, only can produce very little braking force if do not touch on the brake suddenly.In this case, chaufeur is in the rear half stage of braking, and as do not step on brake pedal always, braking force will reduce rapidly.
Summary of the invention
The objective of the invention is: a kind of auxiliary device that can improve the vacuum booster of vehicle safety is provided.
The objective of the invention is to realize like this: the vacuum booster auxiliary device; The sliding sleeve that comprises a side-wall hole is provided with reaction plunger in the sliding sleeve, said reaction plunger front end fixedly installs a taper shoulder; Insert hair clip shape snap close between said sliding sleeve and the reaction plunger; Said snap close is arranged on the front end of the taper shoulder of reaction plunger, and the periphery of sliding sleeve is provided with the sliding sleeve spring, and the sliding sleeve Spring Card is between sliding sleeve rear end and snap close.
The present invention is arranged on the control cock part of vacuum type servo-unit; Be arranged between input bar and the power piston, when using at ordinary times, gently step on brake pedal; The input bar drives reaction plunger and pushes ahead; Because strength is less, travel forward together simultaneously, produce less braking force through taper shoulder drive snap close and sliding sleeve; When the chaufeur that gets deeply stuck in anxiety carries out emergency braking, step on brake pedal fast, this moment, reaction plunger strutted snap close through the taper shoulder, reached the purpose of rapid braking, can guarantee enough braking forces even need not trample with strength also; The shoulder of taper simultaneously blocks snap close, under the effect of sliding sleeve spring, slowly recovers, and in this case, chaufeur is in the rear half stage of braking, even the loosen the brake pedal, the braking force descending speed is also far below the conventional vacuum servo-unit.
The present invention can detect situation about running in the vehicle ' from chaufeur is stepped on the speed of brake pedal; When chaufeur is in case of emergency stepped on brake pedal rapidly; But when pedal force is not enough again; This system just can increase to maximum to braking force and keep a period of time in less than 1 second time, shorten the braking distance under the emergency braking situation, the safety that has improved automobile.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the vacuum booster auxiliary device comprises the sliding sleeve 4 of a side-wall hole; Reaction plunger 5 is set in the sliding sleeve 4; Reaction plunger 5 front ends fixedly install a taper shoulder 2, insert hair clip shape snap close 1 between sliding sleeve 4 and the reaction plunger 5, and snap close 1 is arranged on the front end of the taper shoulder 2 of reaction plunger 5; The periphery of sliding sleeve 4 is provided with sliding sleeve spring 3, and sliding sleeve spring 3 is stuck between sliding sleeve 4 rear ends and the snap close 1.
