Abstract
The invention relates to a brake assistor for an electric automobile. The brake assistor is connected to a brake assisting pump of the automobile and comprises a power supply and an air pump which is driven by the power supply, 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 assisting pump which is communicated with atmosphere. The brake assistor for the electric automobile has the advantages that: 1) an assisting device is connected to an original brake assisting pump and a certain air pressure is supplied by the assisting device, thereby increasing a difference of the pressure on the two sides of the brake assisting pump and reducing a manual braking force, and even if an engine is shut down, the surplus pressure provided by the assisting device, namely the difference of the pressure on the two sides of the brake assisting pump, can be utilized to greatly reduce the manual braking force, thereby easily realizing the braking by an operator; and 2) a filter and a muffler are arranged between the air pump and the air storage tank, thereby effectively preventing the air storage tank from being damaged by the entered grains and impurities in air, lowering the noise and improving a working condition of the operator.
Description
Technical field
The present invention relates to a kind of electronlmobil brake power-assisted, belong to the braking technology field.
Background technology
Artificial brake force when braking in order to reduce electric automobile; Configuration brake boost pump provides brake force on automobile; Its operation principle is: the brake boost pump by the diaphragm separated into two parts, a part and atmosphere, another part links to each other with engine air inlet tube by pipeline; Suck air during engine operation; Cause a side vacuum of brake boost pump, opposite side is an operate as normal air pressure, forms pressure differential between the two; Utilize pressure differential to strengthen brake force, reduce artificial brake force; But there is certain defective in this kind mode of braking, and behind engine misses, 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.
Summary of the invention
The present invention is directed to above-mentioned defective, 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.
Technical scheme of the present invention is: the present invention is connected on the braking automobile boost pump, comprises 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 in the brake boost pump end with atmosphere.
Establish filter between air pump and the storage tank.
Establish silencer between air pump and the storage tank.
Advantage of the present invention is: 1) the present invention 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 present invention establishes filter and silencer between air pump and storage tank, has avoided the entering of particulate and 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 invention
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 air pump 1 that the present invention includes power supply 7 and driven by power supply 7 is sent to storage tank 4 with air pump 1 gas through pipeline during work, 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 preset scope.
The air extractor duct of storage tank 4 of the present invention is connected in the brake boost pump 5 and an end of atmosphere, to improve the difference of pressure at brake boost pump 5 two ends, reduces artificial braking force.
