Description
(1) technical field:
The invention belongs to engineering machinery field, relate to a kind of multifunctional wet multi-disc brake.
(2) background technique:
At present, China's construction machinery product arrestment mechanism adopts caliper disc brake mostly, though it is stable that caliper disc brake has braking ability, can bear influence from temperature, water logging and the speed of a motor vehicle, fade resistance can wait advantage well, but it has single-deck, and friction area is little, and compressive load per unit area is big, operating temperature is high, radiating condition is poor.Along with the continuous development that braking ability is required very strict engineering construction machinery, multi-disk wet brake obtains application more and more widely in recent years.Wet multi-disc brake can be divided into the plain edition wet multi-disc brake, wet multi-disc decompression break, forms such as multifunctional wet multi-disc brake according to installation and working principle.The plain edition wet multi-disc brake adopts the pressure oil brake activation, discharges braking by spring after the release, and it needs a hydraulic system to come the brake activation action, in case the explosion fault appears in pipeline, just can't realize braking, brings threat for the safety traffic of vehicle.In addition,, also need in other parts of power train such as gearbox, locking device for a vehicle be set, increase the power train structural complexity, also be not easy to maintenance simultaneously in order to guarantee to locate safely behind the vehicle parking.Wet multi-disc decompression break structurally adopts dish spring brake activation, by the pressure oil brake off, service braking, stopping brake and emergency braking all thus break finish, bring convenience to general arrangement.But because this break adopts spring-operated braking, braking is impacted big, and is soft inadequately.The dish spring bears fatigue load for a long time in addition, so require all higher to its rigidity, fatigue resistance.
(3) summary of the invention:
The object of the present invention is to provide a kind of functional reliability good, cost is lower, uses easy to maintenancely, can improve the multifunctional wet multi-disc brake of engineering machinery braking reliability.
Technological scheme of the present invention is: multifunctional wet multi-disc brake comprises semiaxis housing 1, housing attachment screw 2, adjustment pad 3, disc 4, stator 5, friction plate 6, spring guider screw 7, pressure spring 8, platen 9, seal ring 10, brake casing 11, parking braking piston packing 12, dish spring 13, dish spring abutment 14, parking braking piston 15, service brake piston 16, service brake piston packing 17, manual brake off screw 18, central housing 19, semiaxis 20.It is characterized in that: semiaxis housing 1, brake casing 11 and central housing 19 connect into an integral body by 16 housing attachment screws 2, form the break inner chamber.Platen 9 is between brake casing 11 and friction plate 6, and pressure spring 8 withstands on platen 9 interior edge faces by spring guider screw 7.11 of platen 9 and brake casings, arrange a service brake piston 16.Arrange a parking braking piston 15 between brake casing 11 and dish spring abutment 14, dish spring 13 is contained between dish spring abutment 14 and the parking braking piston 15.Between platen 9 and disc 4, alternate successively stator 5 and the friction plate 6 of being equipped with, disc 4 and adjustment pad 3 are contained between friction plate 6 and the semiaxis housing 1 successively, and friction plate 6 inner splines connect with the external splines of semiaxis 20.
Three groups of pressure springs 8 uniformly at intervals on described platen 9 circumferencial directions.
On described stator 5 cylindricals 3 circular arc projectioies are arranged, match, with so that stator 5 keeps circumferential registration with three arc grooves on semiaxis housing 1 inner chamber.
Two manual brake off screws 18 are housed on the described semiaxis housing 1.
The present invention can reach following beneficial effect:
Multifunctional wet multi-disc brake combines the characteristics of plain edition and decompression rotating vane type multi-disc brake, it structurally adopts double-piston, two kinds of modes of braking, stopping brake or motor break down and during pipelines from bursting, the hydraulic braking system off-load, the dish spring promotes the braking of Parking piston pressing friction sheet at once, has guaranteed that vehicle driving is safer.This break has been simplified complete machine power train structure, brake soft, easy to operate, be convenient to maintenance, Security is good.
(4) description of drawings:
Fig. 1 is a multifunctional wet multi-disc brake structural representation of the present invention.
(5) embodiment:
As shown in Figure 1: the wet multi-disc brake main parts size is: semiaxis housing 1, housing attachment screw 2, adjustment pad 3, disc 4, stator 5, friction plate 6, spring guider screw 7, pressure spring 8, platen 9, seal ring 10, brake casing 11, parking braking piston packing 12, dish spring 13, dish spring abutment 14, parking braking piston 15, service brake piston 16, service brake piston packing 17, manual brake off screw 18, central housing 19, semiaxis 20.Semiaxis housing 1, brake casing 11, seal ring 10 and central housing 19 connect into an integral body by 16 housing attachment screws 2, form the break inner chamber.Platen 9 between brake casing 11 and friction plate 6, three groups of pressure springs 8 uniformly at intervals on platen 9 circumferencial directions, pressure spring 8 withstands on platen 9 interior edge faces by spring guider screw 7.11 of platen 9 and brake casings, arrange a service brake piston 16.Between brake casing 11 and dish spring abutment 14, arrange a parking braking piston 15, dish spring 13 is contained between dish spring abutment 14 and the parking braking piston 15, and service brake piston 16 forms two oil closed cavities by service brake piston packing 17, parking braking piston packing 12 with brake casing 11 respectively with parking braking piston 15.Between platen 9 and disc 4, alternate successively stator 5 and the friction plate 6 of being equipped with, disc 4 and adjustment pad 3 are contained between friction plate 6 and the semiaxis housing 1 successively.Friction plate 6 inner splines connect with the external splines of semiaxis 20, and three circular arc projectioies are arranged on stator 5 cylindricals, match with three arc grooves on semiaxis housing 1 inner chamber, with so that stator 5 circumferencial directions location.Two manual brake off screws 20 are housed on semiaxis housing 1.
Service brake is controlled by the different oil circuit of two-way oil pressure respectively with stopping brake.Service brake power acts on service brake piston 16 surfaces by pressure oil and produces, when entering pressure oil in service brake piston 16 oil pockets, thereby service brake piston 16 promotes platen 9 makes stator 5 and friction plate 6 compress generation frictional force, the frictional resistance moment that this frictional force forms makes semiaxis 20 stalls, thereby makes wheel braking; When removing service brake, then need pressure oil is laid down, service brake piston 16 breaks away from platen 9 under the effect of pressure spring 8, thereby stator 5 and friction plate 6 are broken away from, and frictional resistance moment disappears, and makes vehicle be in non-braking state.
Parking braking power is produced by dish spring 13, during driving, the pressure oil that enters in parking braking piston 15 chambeies reaches rating value, pressure oil acts on piston 15 surfaces and makes it to break away from platen 9 and compact disc spring 13, be in non-parking braking state, the disengaging of friction plate 6 and stator 5 or compress only relevant with the action of service brake piston 16; Parking braking or motor break down and during pipelines from bursting, pressure oil is laid down, dish spring 13 promotes parking braking piston 15 under the effect of elastic force, thereby promote platen 9, make stator 5 and friction plate 6 compress and produce frictional force, the frictional resistance moment that this frictional force forms makes semiaxis 20 stalls, and wheel braking plays the security insurance effect.
When vehicle is in the parking braking state owing to oil-way system generation problem, can turn manual brake off screw 18 and back down platen 9, stator 5 is separated with friction plate 6, thus brake off.
