Description
Technical field
The invention belongs to automobile inflator pump technical field, specifically a kind of automobile batch (-type) method of work inflating pump.
Background technology
Inflating pump be heavy-duty truck brake system mainly comprise one of parts, be the important leverage of safe driving.Annexation between existing inflating pump and automobile engine has two kinds, and one is to be connected by pulley drive, and another kind is to be connected by gear drive.Either pulley drive connects, or gear drive connects, existing inflating pump is directly connected to automobile engine the most all the time, in automobile engine front crankshaft belt pulley or automobile engine body under the drive of special travelling gear, inflating pump runs simultaneously with automobile engine, automobile engine is not stopped, and its work is more than.Because automobile only just can consume source of the gas in a large number when long descending, abrupt slope brake, brake when wherein meeting obstacle and stop, the source of the gas needed for blowing a trumpet etc. is short-time characteristic, finiteness.Owing to inflating pump is the most ceaselessly to inflate, and the capacity of air tank is limited, for ensureing the safety of its system, properly functioning, when in system, air pressure (in air tank) exceedes predetermined peak, unnecessary superpressure part have to be automatically drained out decompression by the superpressure air bleeding valve being arranged on air tank, so system is inflated circularly, aerofluxus, waste substantial amounts of source of the gas the most in vain, the emptier burden having increased automobile engine simultaneously, waste fuel oil, most importantly air pump is allowed to have done substantial amounts of idle work, air pump is still wearing and tearing while flogging a dead horse, not only increase maintenance cost on foot, but also aggravation shortens its service life, this seems already in the today advocating energy-saving consumption-reducing energetically and is less suitable for, improve very urgent.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned weak point and provides a kind of gear drive and pin disengaging type discontinuous operation inflating pump alleviating automobile engine burden, saving fuel oil, prolongation air pump service life and reducing maintenance cost.
The technical solution of the present invention is: a kind of gear drive and pin disengaging type discontinuous operation inflating pump, including containing travelling gear, crankcase, the inflating pump of bent axle, it is characterised in that: between described bent axle and travelling gear, it is provided with clutch configuration assembly of devices；This clutch configuration assembly of devices includes clutch outer member, clutch cover plate, copper sheathing, relay, arrangement of clutch structure dish；Wherein, clutch outer member is the connector drum that two ends are provided with adpting flange, and connector drum one end is fixed on inflating pump crankcase, and the other end is solid on engine body shell；Clutch cover plate is for being positioned at connector drum and being fixed on bent axle by alignment pin, and clutch cover plate center inside is provided with clutch drive gear axle sleeve；Clutch cover plate is provided with separation pin catch bar movable span, separates and is provided with separation pin return spring cover plate inside pin catch bar movable span side；Copper cover inlay is in travelling gear axis hole, and is sleeved on clutch drive gear axle sleeve；Travelling gear the inner is provided with disk body, and inside disk body, the edge circle of card is provided with and combines pin tooth conjunction groove；Arrangement of clutch structure dish is the disk body being positioned at connector drum outboard end, and arrangement of clutch structure disk center is provided with the through hole coordinated with travelling gear disk body；Inside arrangement of clutch structure dish, card is provided with the loose slot separating pin and return spring of arc, separate pin and separate pin with return spring loose slot built with the return spring being connected and lamellar, separate pin and be provided with separation pin catch bar, separate pin catch bar through separating pin catch bar movable span；Separate pin and be provided with combination pin movable clamp groove radially with return spring loose slot, in conjunction with pin movable clamp groove built with the combination pin that oblique step side is arc, in conjunction with pin top equipped with combining pin return spring, coordinate with combining pin movable clamp groove outer end in conjunction with pin return spring cover plate；Clutch cover plate is connected by Combined clutch fastening screw with arrangement of clutch structure dish；Clutch outer member be provided with separate pin catch bar just to magnetic core loop bar activity slide opening, magnetic core loop bar activity slide opening is built with magnetic core loop bar, being cased with loop bar return spring outside magnetic core loop bar, relay is loaded on clutch outer member, and makes the electromagnetic core of relay be positioned at magnetic core loop bar.
nullDue to the fact that between bent axle and travelling gear equipped with by clutch outer member、Clutch cover plate、Copper sheathing、Relay、The clutch configuration assembly of devices that arrangement of clutch structure dish is constituted，Wherein，Clutch outer member is that one end is fixed on inflating pump crankcase，Clutch cover plate is fixed on bent axle by alignment pin，Clutch cover plate is provided with clutch drive gear axle sleeve、Separate pin catch bar movable span、In conjunction with pin return spring cover plate，Copper cover inlay is in travelling gear axis hole，And be sleeved on clutch drive gear axle sleeve，Disk body edge, travelling gear the inner is provided with and combines pin tooth conjunction groove，Arrangement of clutch structure dish is provided with separation pin and return spring loose slot、In conjunction with pin movable clamp groove，Separate pin and separate pin with return spring loose slot built with the return spring connected and lamellar，Separate pin catch bar through separating pin catch bar movable span，In conjunction with pin movable clamp groove built with the combination pin that oblique step side is arc、And combine pin return spring，Coordinate with combining pin movable clamp groove outer end in conjunction with pin return spring cover plate，Clutch cover plate is connected by Combined clutch fastening screw with arrangement of clutch structure dish，Relay is loaded on clutch outer member，Magnetic core loop bar and loop bar return spring be positioned on clutch outer member with separate pin catch bar just to magnetic core loop bar activity slide opening，The electromagnetic core of relay is positioned at magnetic core loop bar，Thus when gas storage in-cylinder pressure is less than setting value，Electric-control system power-off，Relay remains static，Separate pin under the effect of its return spring，Draw back in cotter way and reply position，Now，Magnetic core loop bar is under the effect of return spring，It is also at return state，Meanwhile，In conjunction with pin under the effect of pin top return spring，Move inwards in combining pin movable clamp groove，Ratcheting with the combination pin tooth of travelling gear conjunction groove，The arrangement of clutch structure dish linkage making travelling gear and be arranged on bent axle，Inflating pump is started working；When the atmospheric pressure in air tank is more than or equal to the maximum amount definite value preset, electric-control system is energized, relay is in running order, under the effect of electromagnetic force, iron core forward extends out, magnetic core loop bar part is forced to stretch in bell housing body, clutch side edge thereof, block separation pin catch bar to rotate, make the separation pin in the clutch configuration dish of rotation move forward in cotter way, under the effect separating pin point, promote to combine pin simultaneously and move upward, separating with driving cog race card, inflating pump quits work.The present invention have alleviate automobile engine burden, saving fuel oil, exponentially extend inflating pump service life and reduce inflating pump maintenance cost feature, thoroughly overturn the working method of traditional inflating pump, allowed the useful life of inflating pump perform to ultimate attainment in automobile brake system.Present invention is mainly used for the service intermittent method inflating pump of truck.
