Abstract
The invention relates to a brake device for a washing machine. The brake device comprises a base, brake springs, brake rods, grooves, fixed holes, friction plates, brake plates and fixed shafts. A central hole and the grooves are formed on the base. The fixed holes are formed on the grooves. One ends of the brake plates are installed on the base through the fixed shafts, and the brake rods are arranged at the other ends of the brake plates. The friction plates are arranged on one sides of the brake plates close to the central hole. The two brake plates are symmetrical to the center line of the central hole, and the two brake springs are arranged on the inner sides of one ends of the two brake plates connected with the brake rods. When being stressed, the brake rods drive the two brake plates to rotate around the fixed shafts simultaneously, and a connection shaft located in the central holes rotates to make the washing machine to run; when the driving force stops, the brake plates quickly return to the starting position under the restoring force of the two brake springs to contact the connection shaft, the connection shaft stops rotating, and the washing machine stops running. The brake efficiency of brake discs is improved due to simultaneous acting of the two brake springs, and the service lives of the brake springs and the friction plates are prolonged.
Description
Technical field
The present invention relates to washing machine FIELD OF THE INVENTIONThe, particularly, relate to a kind of brake apparatus for washing machine.
Background technology
twin-tub semi-automatic washing machine, when dewatering, if there is special circumstances, needs in dehydration barrel, to take out clothing immediately.By People's Republic of China's national regulations, require that dehydration lid starts power-off after 50mm, and dehydration barrel rotating speed is down to below r/min in 7s, Here it is brake process, this brake process relies on brake disc to brake, short time and high-frequency braking this just have serious loss to the tripping spring on brake disc and friction plate.At present, the tripping spring on brake disc and the service life of friction plate are general shorter, and need often change, this brings huge inconvenience to the use of washing machine, and the ability recovering deformation after spring uses a period of time dies down, and retardation efficiency is reduced.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of brake apparatus for washing machine, to overcome the low problem of brake disc retardation efficiency.
The present invention's adopted technical scheme that solves the problem is: a kind of brake apparatus for washing machine, comprise base, tripping spring, brake lever, groove, fixing hole, friction plate, braking vane, fixed axis, pedestal offers centre bore, groove, groove starts there is fixing hole, braking vane one end is fixed on base by fixed axis, the other end is provided with brake lever, braking vane is provided with friction plate near centre bore side, described braking vane centrally hole center line is symmetrically arranged with two, is provided with two tripping springs inside one end of two braking vanes connection brake levers.By centre bore, motor and connecting axle are linked together, described braking vane can rotate around fixed axis, friction plate also has arcuate structure, thus energy is good and braking vane fits together, fit structure of the present invention: the connecting rod of motor passes the centre bore of brake disc, by fixing hole, brake disc is fixed on motor with screw, the connecting rod again connecting axle being inserted motor is fixed on brake disc, during work, braking vane leaves the connecting axle of its parcel under the effect of driving force, when emergency needs braking, because two tripping springs shrink simultaneously, produce and recover deformation power, this deformation recovers to make braking vane get back to initial position fast and contacts with connecting axle, because two braking vanes extrude connecting axle simultaneously, well connecting axle can be blocked, make it to maintain static, thus braking action can be played fast, improve retardation efficiency.
Further, brake lever is provided with guide seats.Brake lever directly acts on braking vane, and the braking vane direction of motion can be made uncertain, when stressed larger time braking vane can depart from base; Moved on base by guide seats, braking vane well can be fixed on base, and whole brake lever is led, more easily control the movement of brake lever.
Further, brake lever is helical spring structure.Helical spring is as drives structure, make whole drive ratio comparatively flexible, the change that direction can be suitable according to actual conditions, because spring has certain deformation, there is individual buffering course when no matter being and driving or brake, the stressed of whole brake lever is also relaxed relatively.
Further, braking vane and friction plate junction are the inside arcuate structure in the center of circle, and braking vane is connected for slab construction with tripping spring, and this arcuate structure and slab construction junction are the outside arcuate structure in the center of circle.Arc structure not only makes brake disc be connected closely with connecting axle, and more flexible when rotating.
Further, friction plate adopts Wear-resistant engineering plastic.Common plastic friction coefficient is comparatively large, and under high strength, high-frequency extrusion friction, easily deformation occurs in heating, and loss is larger; Wear-resistant engineering plastic is prior art material, it has relatively low coefficient of friction, when friction plate is contacted with connecting axle, friction is less, simultaneously, because the heat radiation caused that rubs also reduces after frictional force reduces, thus the loss making friction plate receive because being heated also reduces, thus improve the use birthday noodle of friction plate, indirectly improve the service life of whole brake disc.
Further, tripping spring is the Compress Spring adopting carbon spring steel wires to make.The elastic recovery capability of common spring is poor, makes spring cannot recover deformation in use for some time, causes playing braking effect; Carbon spring steel wires is prior art material, intensity is high, performance good, stress is high feature that it has, and especially axially has good contracting strength, has good elasticity and recovers deformability.
To sum up, the invention has the beneficial effects as follows:
1, the retardation efficiency of brake disc improves.
2, tripping spring and friction plate improve service life.
