Abstract
The utility model discloses a driving axle of vibratory road roller with three pairs of brake calipers at single side, which comprises a driving axle hub, a brake disc, a driving axle shell and brake calipe, wherein the brake disc is connected fixedly with the driving axle hub, the driving axle shell is connected with the brake caliper, the brake caliper is connected with a brake oil pipe, a brake plate is arranged fixedly on the brake caliper, the brake calipers are distributed at two sides of the brake disc, three pairs of brake calipers are provided at each side of the brake disc and distrusted evenly on the driving axle shell. In the utility model the main body structure of the prior driving axle is not changed, the brake torque of the driving axle is improved by the supernormal means of adding brake calipers, the quantities of brake calipers at each side are increased from 2 pieces to 3 pieces. By adding the quantities of the brake calipers, the brake force is added, and the brake torque is also added in the case of no adding brake radius. The utility model provides a reliable dynamic torque for heavy type vibratory road roller, simultaneously the development of the single-driving heavy type vibratory road roller also becomes possible.
Description
Technical field
The utility model technology belongs to roller drive axle braking technology, relates generally to a kind of one-sided vibratory roller drive axle with three auxiliary brakes pincers.
Background technology
The walking of mechanical vibration roller is as shown in Figure 1: be to drive little change speed gear box 3 by driving engine 1 by power-transfer clutch 2, by transmission shaft 4 power is passed to big change speed gear box 5, and then power is sent on the main gear device of drive axle 7 by transmission shaft 6, and each semiaxis about passing through, power is passed on the final planetary wheel of bridge, the planetary wheel of both sides drives tire 8 and rotates, and makes complete machine advance or retreats, thereby make the roller walking.The service brake of travelling is to be undertaken by the caliper disk brake of installing on the axle housing of drive axle.Traditional drive axle generally adopts two clipper disk brakes of 180 ° of symmetrical distributions on one side, and four braking clamps compress two brake discs and realize drag under the control of hydraulic circuit.Be existing drive axle simple structure scheme drawing as accompanying drawing 2,3, drive axle wheel hub 9 and brake disc 10 that walking is rotated are linked together, changeless drive axle axle housing 13 passes through Bolt Connection together with braking clamp 12, and mainly the brake facing of being made up of friction material 11 is fixed on the braking clamp 12.Drive axle brake principle as shown in the figure, when we need service brake, step on brake pedal, the high pressure brake solution enters in the braking clamp 12 by brake oil pipe, braking clamp 12 compresses brake disc 10 by driving brake facing 11, the wheel hub 9 of both sides on the drive axle is stopped operating, realize vehicle service brake in the process of moving.Along with the fast development of highway construction, increasing on the market to large-tonnage roller demand, particularly more than 20 tons the ton the mechanical drive road roller rush of demand.Because the growth of roller tonnage, the brake torque of one-sided two pairs of conventional drive bridge, the common fourth officer braking clamp in both sides can not satisfy the drag performance of roller more than 20 tons now, if still use traditional drive axle braking, brake torque can not meet design requirement, skidding will appear in the roller service brake, have potential danger.The method of traditional increase brake torque generally is to strengthen the diameter of brake disc 10, increase the braking radius with this, thereby increase the moment of torsion of braking, but because the restriction of this class type overall dimensions, the external diameter of brake disc 10 can not add very big, otherwise will influence fitting of tire.
Summary of the invention
The purpose of this utility model provides a kind of one-sided vibratory roller drive axle with three auxiliary brakes pincers, makes it have one-sided three pairs, the both sides braking clamp of totally six pairs, and the service brake moment of torsion increases greatly, has improved braking quality.
The purpose of this utility model can adopt following technical scheme to realize: it comprises drive axle wheel hub, brake disc, drive axle axle housing and braking clamp, brake disc and drive axle wheel hub are fixed, drive axle axle housing and braking clamp connect, braking clamp is connected with brake oil pipe, be fixed with brake facing on the braking clamp, be distributed in the braking clamp of brake disc both sides, every side is three pairs, is distributed on the drive axle axle housing.
Drive axle described in the utility model does not change the agent structure of existing drive axle, and it is the brake torque that improves drive axle by the method for unconventional increase brake clamp, and the quantity of the braking clamp of every side increases to 3 pairs by 2 pairs.By increasing the method for brake clamp quantity, increased braking force, under the situation that does not increase the braking radius, increased brake torque.The utility model makes single exploitation that drives heavy vibratory roller become possibility for heavy vibratory roller service brake provides the failure-free kinetic moment simultaneously.

Accompanying drawing 2 is existing roller drive axle structural representations.
Accompanying drawing 3 is that the A of Fig. 2 is to view.
Accompanying drawing 4 is structural representations of the present utility model.
Accompanying drawing 5 is that the B of Fig. 4 is to view.
Among the figure: 1, driving engine, 2, power-transfer clutch, 3, little change speed gear box, 4, transmission shaft, 5, big change speed gear box, 6, transmission shaft, 7, drive axle, 8, tire, 9, wheel hub, 10, brake disc, 11, brake facing, 12, braking clamp, 13, the drive axle axle housing, 14, brake oil pipe, 15, braking clamp.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
Shown in accompanying drawing 4,5: it comprises drive axle wheel hub 9, brake disc 10, drive axle axle housing 13 and braking clamp 15, brake disc 10 and drive axle wheel hub 9 are fixing, drive axle axle housing 13 and braking clamp 15 connect, braking clamp is connected with brake oil pipe, be fixed with brake facing 11 on the braking clamp 15, braking clamp is distributed in the brake disc both sides, and every side is three pairs, be distributed on the drive axle axle housing 13 120 ° of distributions between promptly every two adjacent auxiliary brakes pincers 15.
The quantity of the braking clamp 15 of the every side of present embodiment increases to 3 pairs by 2 pairs, and bilateral is 6 pairs.By increasing the method for brake clamp 15 quantity, increased braking force, under the situation that does not increase the braking radius, increased brake torque.The overall ratio of this drive axle is 27.135, and central speed ratio is 6.617, and wheel limit speed ratio is 4.4, and output torque is 75KNM, and both sides totally six secondary brake clamp brake torques are 60KNM, are suitable for wheel rim 25 ", drg operation pressure 10MPA.The used drive axle of the utility model and existing 20 tons of single-drum road rollers is compared braking quality and has been improved 50% (brake torque of existing drive axle is for being 40KNM).
