Abstract
The utility model discloses a novel 435 axle convenient to maintain. The novel 435 axle convenient to maintain comprises a rim, a hub, a hub outer bearing, a half axle, a hub inner bearing and a locking nut, wherein a brake part composed of a brake drum and a brake shoe is arranged on the hub, a dust guard is arranged outside the brake drum, and a fastening clamping groove in clamping-connection fit with a friction sheet is formed in the outer surface of the brake shoe. According to the novel 435 axle convenient to maintain, when a brake is maintained, only the light and thin dust guard needs to be disassembled, the friction sheet is unloaded and loaded from the movable end of the clamping groove, and operation is convenient and fast. The maintenance cost is reduced to the maximum extent, the maintenance time is shortened to the maximum extent, and the utilization benefit for users is improved.
Description
Technical field
The utility model relates to mechanical field, novel 435 vehicle bridge of specifically a kind of convenient maintenance.
Background technology
435 traditional bridges just can carry out the replacing of friction lining because of the restriction that is subjected to space and fastening means after must first brake wheel wheel hub one cover being removed when drg is safeguarded, its maintenance workload is quite heavy, namely time-consuming again the effort and also can cause damage to semiaxis and hub bearing.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved in the utility model is, to provide a kind of and to simplify the car brake handling labor in order reaching, reduce maintenance cost and protect novel 435 vehicle bridge of the convenient maintenance of transmission environment purpose.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of novel 435 vehicle bridge of convenient maintenance, comprise wheel rim, wheel hub, wheel hub outer bearing, semiaxis, hub inner bearing and jam nut, the brake portion that is comprised of brake wheel and brake shoe iron is set on the described wheel hub, dust boot is set outside brake wheel, it is characterized in that: described brake shoe iron outside face offers the fastening draw-in groove that cooperates with the friction lining clamping.
Novel 435 vehicle bridge of above-mentioned convenient maintenance, described fastening draw-in groove is arranged on the dust boot inboard.
The advantage of novel 435 vehicle bridge of the convenient maintenance of the utility model is: for reducing maintenance cost, protection transmission environment, existing novel 435 vehicle bridge that original design 435 bridges are improved to the convenient maintenance of assembling card slot type New Brake.
1, handling labor is simple and convenient
During common 435 bridge service brakes, after needing first wheel hub brake wheel one cover to be dismantled, bolt, the rivet dismantled on the friction lining come more renewal of facing renewal again.The replacing of friction lining is that perseverance safeguards that number of times is more, safeguards that total expenses is huge to car load.And after novel 435 vehicle bridge of convenient maintenance carry out only frivolous dust boot to be unloaded when drg is safeguarded, from the movable end of draw-in groove friction lining is withdrawn from and is packed into getting final product, convenient and swift.Farthest reduce maintenance cost and maintenance time, improved user's utilization benefit.
2, protection transmission environment
During common 435 bridge service brakes, wheel hub, brake wheel, hub bearing and semiaxis all will unload first the replacing of carrying out again friction lining, ressemble after replacing is finished again.In dismounting and the process of ressembling dust enter axle assembly internal contamination transmission environment simultaneously Transmission externally also can be corroded in the environment.And the assembly technique of considering the public service station also can cause in various degree secondary injury to semiaxis and hub bearing; Novel 435 vehicle bridge of convenient maintenance have then thoroughly solved this problem, in whole drg maintenance process, need not change any drive disk assembly, complete maintenance original transmission environment and thoroughly avoided the injury of secondary assembling.
3, deceleration and stopping performance improves
The new construction drg of coupling so that the frictional area of friction lining increases simultaneously, has improved the deceleration and stopping performance of car load because having cancelled fastener hole.
4, economical and efficient
The designs simplification of friction lining and brake shoe iron has been saved tooling cost and has been improved simultaneously production efficiency so that manufacturing procedure reduces.
Description of drawings
Fig. 1 is the structural representation of common vehicle bridge brake portion;
Fig. 2 is constructional drawing of the present utility model.
The specific embodiment
In conjunction with the drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, common 435 vehicle bridge are first step during renewal of facing renewal more, removes tire, wheel rim part.Second step is backed out half axle bolt, removes sealant, and semiaxis is unloaded.In the 3rd step, the unload lock jack panel is pulled down the wheel hub brake drum assembly.In the 4th step, remove more renewal of facing renewal of rivet or bolt.In the 5th step, the dust on the cleaning bearing semiaxis is smeared grease.The 6th step is in order with each parts successively installation.
As shown in Figure 2, a kind of novel 435 vehicle bridge of convenient maintenance, comprise wheel rim 1, wheel hub 2, wheel hub outer bearing 3, semiaxis 4, hub inner bearing 5 and jam nut 6, be provided with the brake portion that is formed by brake wheel 7 and brake shoe iron 8 at wheel hub 2, at the brake wheel 7 outer dust boots 9 that arrange, offer the fastening draw-in groove 10 that cooperates with the friction lining clamping at the outside face of brake shoe iron 8.Fastening draw-in groove 10 is arranged on the inboard of dust boot 9.More during renewal of facing renewal, the first step is removed dust boot to novel 435 vehicle bridge of convenient maintenance.Second step takes out old friction lining from draw-in groove is movable, movable end is locked after inserting new friction lining.In the 3rd step, dust boot is installed.
Drg of the present utility model adopts the fastening friction lining of draw-in groove, and with simple in structure, time saving and energy saving, simple operation, reliability is high has finally determined present design plan for design starting point by contrast of multiple-schemes.The utility model has been abandoned the drg of old structure, has courageously adopted draw-in groove fastening-type drg.At the fastening draw-in groove of brake shoe iron design: be respectively three fastening and one side is detachable, detachable draw-in groove is positioned near dust boot one side.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (2)
1. novel 435 vehicle bridge of a convenient maintenance, comprise wheel rim, wheel hub, wheel hub outer bearing, semiaxis, hub inner bearing and jam nut, the brake portion that is comprised of brake wheel and brake shoe iron is set on the described wheel hub, dust boot is set outside brake wheel, it is characterized in that: described brake shoe iron outside face offers the fastening draw-in groove that cooperates with the friction lining clamping.
