Abstract
The utility model relates to a brake for a bulldozer, and belongs to the technical field of engineering machinery. The brake is used for improving the safety of bulldozer operation and adopts the technical scheme that the brake comprises a brake housing, a driven hub and a braking clutch, wherein the brake housing is fixedly connected with a bulldozer body, and the driven hub is fixed on an output shaft by splines, connected with the brake housing by the braking clutch, and connected with a driving hub by a driving clutch. The brake adopts the braking clutch to substitute the traditional belt mechanism and adopts a disc spring to substitute a hydraulic power-assisted system, the disadvantages existing in the traditional belt braking mechanism and a hydraulic power-assisted braking system are overcome, potential safety hazards due to the belt braking mechanism or hydraulic oil circuit faults are avoided, the braking response speed and braking reliability of the bulldozer are improved, and the travelling and operation safety of the bulldozer can be ensured.
Description
Technical field
The utility model relates to a kind of high reliability clutch type dish spring brake for bulldozer, belongs to technical field of engineering machinery.
Background technology
Bulldozer is a kind of engineering machinery commonly used, and good braking ability is most important to the safety that improves bulldozer.Traditional bulldozer brake adopts belt mechanism and hydraulic booster mode more, because it is longer that belt mechanism is handled the path, break down unavoidably in the use procedure, and hydraulic booster system is easier of the hydraulic circuit problem lost efficacy, this has just brought hidden danger for the safety of bulldozer.In order to improve the reliability of complete machine, guarantee people's safety of life and property, be necessary the bulldozer brake that research and design is novel.
The utility model content
The purpose of this utility model is the bulldozer brake that overcomes the deficiencies in the prior art, a kind of high reliability is provided, improves the safety of bulldozer.
Problem described in the utility model is realized by following technical scheme:
A kind of bulldozer brake, it comprises brake casing, driven hub and brake coupling, described brake casing is fixedly connected with the bulldozer body, described driven hub is fixed on the output shaft by spline, and driven hub is connected with brake casing by brake coupling and is connected with drive hubs by transmission clutch.
Above-mentioned bulldozer brake, described brake coupling comprises ring-type braking inner attrition piece, ring-type braking outside friction disc and the ring-type braking compression plate of coaxial arrangement, described braking inner attrition piece all arranges a plurality of with the braking outside friction disc, they are spaced, inner edge and the driven hub of braking inner attrition piece are affixed, and the outer rim of braking outside friction disc is connected with brake casing; The one side that described braking compression plate is relative with the braking outside friction disc with the braking inner attrition piece is provided with pressure oil cavity, and another side joins by dish spring and brake casing.
The utility model replaces traditional belt mechanism with brake coupling, replace hydraulic booster system with the dish spring simultaneously, overcome the shortcoming that conventional belt arrestment mechanism and braking system with hydraulic assisting force exist, avoided because the potential safety hazard that belt braking mechanism or hydraulic circuit fault are brought, improve braking response speed and the braking reliability of bulldozer, can guarantee the safety of bulldozer driving and operation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Each label is among the figure: 1, drive hubs; 2, transmission inner attrition piece; 3, transmission outside friction disc; 4, driven hub; 5, clutch compression plate; 6, braking inner attrition piece; 7, braking outside friction disc; 8, brake casing; 9, braking compression plate; 10, dish spring; 11, output shaft.
The specific embodiment
Referring to Fig. 1, the utility model mainly by driven hub 4 consist of, brake coupling and brake casing 8 consist of, wherein brake coupling is made of braking compression plate 9, braking inner attrition piece 6 and braking outside friction disc 7.Transmission inner attrition piece 2 among Fig. 1, transmission outside friction disc 3 and clutch compression plate 5 consist of transmission clutches, the combination of control drive hubs 1 and driven hub 4 with separate.
Operating principle:
When braking inner attrition piece 6 and braking outside friction disc 7 were compacted, the bulldozer driving wheel was in on-position.When bulldozer is in transport condition, hydraulic pressure comes oily promotion braking compression plate 9 to move right, thereby decontrol braking inner attrition piece 6 and braking outside friction disc 7, clutch compression plate 5 is come oily promotion left by hydraulic pressure simultaneously, compress transmission inner attrition piece 2, transmission outside friction disc 3, power is delivered to driven hub 4 by drive hubs 1 by the friction plate effect, is delivered to output shaft 11 by spline again.
When motor is in flameout state, braking compression plate 9 will be braked inner attrition piece 6 and braking outside friction disc 7 compressions under the effect of dish spring 10, make complete machine be in reliable on-position.After engine start, come under the oily effect at hydraulic pressure, braking compression plate 9 moves right, to brake inner attrition piece 6 loosens with braking outside friction disc 7, in case and engine misses, braking compression plate 9 will compress braking inner attrition piece 6 and braking outside friction disc 7 under the effect of dish spring 10, thereby complete machine is reliably braked.
When being in emergency and needing stopping brake, by stepping on brake pedal, cut off hydraulic pressure oily, dish spring 10 will make rapidly braking compression plate 9 compress braking inner attrition pieces 6 and braking outside friction discs 7 like this, thereby reliably brakes.
When bulldozer need racing to the time, spur corresponding brake handle, will cut off a side hydraulic pressure and come oilyly, braking compression plate 9 compresses braking inner attrition pieces 6 and braking outside friction discs 7 under the effect of dish spring 10, the bulldozer single shoe brake, thereby realize racing to.
