Abstract
The utility model relates to a novel brake booster for an electric vehicle, which is connected to a vehicle brake boosting pump and comprises a power source and an air pump driven by the power source, wherein the air pump is connected to an air inlet of an air storage tank, and an air outlet of the air storage tank is connected to one end of the brake boosting pump, which is communicated with the atmosphere. The brake booster is characterized in that 1, the booster is connected to the existing brake boosting pump, and the brake boosting pump can provide certain air pressure, so that pressure difference between two sides of the brake boosting pump is increased, and manual braking effort is reduced. Even when an engine is flamed out, the spare pressure provided by the booster serves as the pressure difference between two sides of the brake pump, and accordingly manual braking effort is reduced greatly and an operator can realize braking easily; and 2, a filter and a silencer are arranged between the air pump and the air storage tank, thereby effectively avoiding damages to the air storage tank caused by particles and impurities in the air entering into the air storage tank, and simultaneously reducing noise and improving working environment of operators.
Description
Technical field
The utility model relates to a kind of electronlmobil brake power-assisted, belongs to the braking technology field.
Background technology
In order to reduce the artificial braking force of electronlmobil glancing impact, configuration brake boost pump provides braking force on automobile, its principle of work is: the brake boost pump is by the diaphragm separated into two parts, and a part communicates with atmosphere, and another part links to each other with engine air inlet tube by pipeline, aspirated air during engine operation, cause a side vacuum of brake boost pump, opposite side is a normal operation air pressure, forms difference of pressure between the two, utilize difference of pressure to strengthen braking force, reduce artificial braking force; But there is certain defective in this kind brake mode, and behind engine off, intake vacuum does not exist especially, and braking this moment needs to lean on fully artificial foot-operated, and required artificial strength is very big, causes braking time long easily, causes potential safety hazard.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of further minimizing artificial braking force, is convenient for people to easily realize the electronlmobil brake power-assisted of braking.
The technical solution of the utility model is: the utility model is connected on the braking automobile boost pump, comprise power supply and by the air pump of power drives, air pump is connected on the admission port of storage tank, and the air extractor duct of storage tank is connected an end that is communicated with atmosphere in the brake boost pump.
Establish filter between air pump and the storage tank.
Establish silencer between air pump and the storage tank.
The utility model has the advantages that: 1) the utility model connects a work-saving device on original brake boost pump, this work-saving device provides certain air pressure, the difference of pressure of brake boost pump both sides is increased, thereby reduce artificial braking force, even behind engine off, the unnecessary pressure that work-saving device provides is the difference of pressure of brake boost pump both sides, also can significantly reduce artificial braking strength, makes operating personal realize braking easily; 2) the utility model is established filter and silencer between air pump and storage tank, has avoided particulate and entering of impurity in the air effectively and to the damage that storage tank causes, reduces noise simultaneously, improves the working environment of operating personal.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that air pump, 2 is that filter, 3 is that silencer, 4 is that storage tank, 5 is that brake boost pump, 6 is that control setup, 7 is a power supply among the figure.
The specific embodiment
The utility model comprises power supply 7 and the air pump 1 that is driven by power supply 7, during work air pump 1 gas is sent to storage tank 4 by pipeline, establishes filter 2, silencer 3 between air pump 1 and the storage tank 4; Control setup 6 detect in real time in the storage tanks 4 air pressure and with this mode of operation of adjusting air pump 1, the air pressure in the storage tank 4 are remained within the default scope.
The air extractor duct of the utility model storage tank 4 is connected an end that is communicated with atmosphere in the brake boost pump 5, to improve the difference of pressure at brake boost pump 5 two ends, reduces artificial braking force.
