Description
Technical field
The present invention relates to hydraulic vehicle brake system improvement technical field, in particular to a kind of improvement brake fluid system
With emptying equipment and brake fluid system modification method.
Background technique
Brake is that vehicle (automobile or motorcycle) is made to slow down or the device of parking, it is common there are two types of, one kind being called dish
Formula brake, another drum brakes, their principle are the same, and are all to generate brake force, this brake quilt using friction
Referred to as friction type brake, the working principle of dish brake fluid system are that the dish of one piece and wheel synchronous rotary is installed on wheel hub
Disk, and the device clamp on front fork and vehicle frame are equipped in clamp and drive brake shoes to abut against with disc, system by piston
Dynamic oil pump is connected by hydraulic tube with piston, and brake pump oil supply driving piston motion simultaneously abuts against with disc and reaches brake
Purpose.
This brake fluid system of vehicle drives only by brake pump at present, and brake pump disposably gives oil mass
It is larger, it often will lead to piston and abut to obtain tension with disc quickly, so that locking phenomenon is generated, and it is extremely dangerous, it be easy to cause
Traffic accident.It is directed to most of the evolutionary approach of brake fluid system of this kind of vehicle at present are as follows: hydraulic tube is truncated, in liquid
Hydraulic ABS (antilock brake system) is added in pressure pipe, the chief component of hydraulic ABS generally comprises braking pressure
Power adjusts unit, electronic control unit and wheel speed sensors etc., and wherein brake pressure adjusts the executing agency that unit is hydraulic ABS
(normally open valve and normally close valve are equipped in the executing agency of hydraulic ABS), main function is to receive the finger from electronic control unit
It enables, the on-off by controlling hydraulic tube directly or indirectly adjusts clamp inner piston to the pressure of disc, is maintained at each wheel
Ideal on-position, hydraulic ABS can control the oil that every task only injects one milliliter or so during braking.
But during hydraulic ABS is installed in hydraulic tube, inevitably enter air in hydraulic tube, and then in brake fluid
Middle generation bubble, to influence the braking ability of entire brake fluid system.In order to eliminate these bubbles, all it is currently on the market
By unscrewing the bleed screw on hydraulic tube, then again by touch on the brake bit by bit inject fresh oil (because of the presence of hydraulic ABS,
Usually step on primary one milliliter of oiling or so of brake), it will be squeezed out with bladdery brake fluid, to realize entire Hydraulic braking system
Zero bubble in the hydraulic tube of system, but as one can imagine this mode for eliminating bubble is very complicated, efficiency is very low, so have
It is to be modified.
Summary of the invention
The object of the present invention is to provide a kind of improvement brake fluid system emptying equipment and brake fluid system improvement sides
