Abstract
An electrically controlled brake unit serially connected between braking master pump and braking branch pump for providing additional braking function is composed of hydraulic pump, one-way valve and motor.
Description
Technical field
The present invention is a kind of electrical controlled brake of traveling crane, is meant a kind of additional brake that is independent of the running brake system especially, belongs to running safety method field.
Background technology
The running brake system has or not the dynamic brake source by it, be divided into power service brake non-power service braking system two classes of unifying, non-power service braking system major part is a hydraulic brake system, relies on chaufeur the application force that brake pedal applies is realized service brake.This type of automobile is implemented service brake if increase autonomous cruise speed system, at first needs to solve the braking force source, secondly is the automatic control service braking system and being connected and isolation of former service braking system.Multiple solution is arranged in the prior art, as utilize the motor traction directly to drag brake pedal; Hydraulic actuating cylinder in parallel on the brake pedal arm; Series connection inserts the hydraulic brake mechanism in self-powered source etc. in the driving brake piping, Chinese invention patent application as publication number CN1215005A, a kind of stop mechanism parallel with the running brake system disclosed, the Chinese invention patent application of CN1473730A discloses a kind of braking mechanism in being connected in the running brake circuit.Though technique scheme can satisfy the basic demand of automatic control service brake, all there are defectives such as complex structure, installation (particularly repacking) difficulty and cost be higher.
Summary of the invention
It is a kind of electrical controlled brake of traveling crane that major part is formed with the little displacement hydraulic pump of high pressure that the present invention proposes a kind of, form by Hydraulic Pump, check valve and electrical motor, after electrical controlled brake of traveling crane series connection inserts the master brake cylinder of running brake system, brake cylinder (or ABS hydraulic pressure regulator) is preceding.When chaufeur was implemented conventional service brake, the master brake cylinder braking liquid flowed into through the Hydraulic Pump oil inlet, flows to ABS hydraulic pressure regulator or brake cylinder by oil outlet again, and check valve provides accelerated passage for braking liquid.During brake off, wheel cylinder inner high voltage braking liquid flows back to the master brake cylinder fluid reservoir through Hydraulic Pump, and original performance of running brake system is unaffected.
During electrical controlled brake of traveling crane work, Hydraulic Pump starts running, and braking liquid is sucked by master brake cylinder, forms high hydraulic brake fluid oil stream and flows to ABS hydraulic pressure regulator or brake cylinder, sets up the brake cylinder line pressure, realizes the automatic control running braking function.After automatic control service brake process finished, brake cylinder pipeline inside brake liquid flowed back to the master brake cylinder fluid reservoir through Hydraulic Pump (utilizing the natural leak after Hydraulic Pump is shut down), and the brake piping internal pressure descends, and the running brake system returns to normal.
The present invention has tangible creativeness and definite beneficial effect than prior art, the electrical controlled brake of traveling crane that the present invention proposes, and have: 1, simple for structure, with low cost, this electrical controlled brake of traveling crane only has three elements; 2, this electrical controlled brake of traveling crane series connection inserts the running brake system, utilizes running brake system braking liquid to be hydraulic medium, the running brake system is not had interfere and influence; 3, have and be swift in response, reliably the outstanding advantage of non-maintaining or reduced-maintenance,, optimization more reasonable than the prior art scheme.

Fig. 3 is automatically controlled service braking system schematic diagram of prior art and and running brake system (ABS is arranged) connection diagram.
Embodiment
With reference to the accompanying drawings the technical solution of the present invention and the specific embodiment are elaborated below.1 is the automobile brake master cylinder among Fig. 1, is the electrical controlled brake of traveling crane schematic diagram in the frame of broken lines 2, and electrical controlled brake of traveling crane is made up of with electrical motor 5 duplex Hydraulic Pump 3 and 3 ', check valve 4 and 4 '.The embodiment of the invention adopts the little displacement gear pump of high pressure, nominal working pressure 16Mpa, discharge capacity 0.35ml/r, electrical motor no load speed 4000r/min, fully loaded 1500r/min, Hydraulic Pump per second discharge the about 20ml of high pressure oil stream, calculate according to the required oil mass 3ml of running brake system (every pipeline)～5ml, Hydraulic Pump can be set up brake-pressure about 200ms, satisfy the technical requirements of running braking.
Fig. 3 is the automatically controlled service braking system typical technology of a prior art scheme schematic diagram, this scheme adopts Hydraulic Pump, electrical motor, check valve, energy storage, bogie type isolation cylinder, two-position two-way solenoid valve nearly ten devices such as (four), has deficiencies such as complex structure, malfunctioning node are many, with high costs.
The embodiment of the invention is only used Hydraulic Pump, three devices of check valve and electrical motor, succinctly reasonable than the prior art scheme, during electrical controlled brake of traveling crane work, electrical motor 5 is driven by electronic control circuit (ECU) 7, drive duplex Hydraulic Pump 3 and 3 ' running, the function of ECU has three, the one, send the service brake instruction according to the automobile real-time status, the 2nd, regulate motor speed according to each vehicle required braking force, (substituting by pass valve) set in the adjusting of finishing the Hydraulic Pump delivery pressure, the 3rd, output pulsed drive power, drive Hydraulic Pump and make discontinuous running, thereby make the brake-pipe pressure pulsation, make automatically controlled service brake produce " continuity point braking " effect, avoid not having the long-time locking of ABS function automotive wheel (have ABS function automobile and can close the pulsed drive function).After the Hydraulic Pump running, check valve 4 and 4 ' stops braking liquid to reflux, and the high hydraulic brake fluid of Hydraulic Pump oil outlet flows to ABS hydraulic pressure regulator 8 rapidly or brake cylinder 6 produces braking force.After the automatic control service brake stopped, because Hydraulic Pump shuts down, its inner natural leak made brake cylinder pipeline inside brake liquid flow back to the master brake cylinder fluid reservoir, and the brake cylinder pipeline inner pressure drops to zero, and braking is removed.
In the automatic control service brake process, if chaufeur is implemented service brake, electronic control circuit (ECU) 7 is by the closure of the mobile or brake switch of sensor monitors brake pedal, monitor the service brake behavior of chaufeur, thereby suppress automatic control service brake process, the operation control that guarantees chaufeur is preferential, avoids chaufeur that controlling of automobile is interfered.
When chaufeur is implemented service brake, braking liquid in the master brake cylinder 1 flows into the oil inlet port of left and right sides duplex Hydraulic Pump 3 and 3 ' respectively, via the oil outlet port flow of Hydraulic Pump to ABS hydraulic pressure regulator 8 or brake cylinder 6, check valve 4 and 4 ' is realized running braking function for service brake provides accelerated passage; When needing brake off, chaufeur loosen the brake pedal, brake cylinder inner high voltage braking liquid is through Hydraulic Pump (natural leak, field data show, the Hydraulic Pump natural leak can make brake-pipe pressure drop to zero in 100ms～200ms, satisfies the technical requirements of brake off fully in the running brake system 800ms.) flow back to the master brake cylinder fluid reservoir, braking is removed.
