Abstract
The utility model relates to vehicle engineering, and aims at providing a full-suspended disk brake rear axle. The full-suspended disk brake rear axle comprises a drive half shaft and an axle shell which wraps the drive half shaft. An outer rotary body and a disk brake plate which are connected with each other are arranged at two ends of the axle shell. One end of the outer rotary body is embedded into the disk brake plate, the other end of the outer rotary body is fixedly connected with the top end portion of the drive half shaft through a half shaft bolt, and a bearing is arranged between the outer rotary body and the axle shell. When a vehicle is heavily loaded, all force of gravity acts on the outer rotary body, and the outer rotary body transmits the force to the axle shell through the bearing, and therefore the drive half shaft is avoided of the weight of load. However, due to the fact that the intensity of the axle shell is far higher than that of the drive half shaft, the axle shell can bear the load of the vehicle so that the drive half shaft only bears drive load. Therefore, service life of the drive half shaft is greatly prolonged, and flywheel safety accidents are avoided.
Description
Technical field
The utility model relates to Vehicle Engineering, refers to especially a kind of full suspension disc brake back axle.
Background technology
Because the braking force of hub formula brake is strong and reliability is high, therefore be that more heavy-duty vehicle adopts.But in the situation of continuously brake, the brake facing cal val is high, causes easily brake facing Yin Gaowen and produces the heat fade phenomenon, and it is limited finally to affect braking effect, year in service life.Especially when long descending was longer, touching on the brake for a long time can be to making temperature drift, and easy burn-out pushes away oily piston packing ring, causes leakage of oil, without brake.
Because the disc brakes thermal diffusivity is good than drum brakes, when trampling continuously brake, more can not cause the phenomenon of braking decline and making brake failure, therefore obtained extensive utilization in brake system.But in the existing technology, back axle adopts mostly is half floated disc brake structure, and car load carrying force and driving force are all born by semiaxis, and the semiaxis that very easily fractures when carrying force is excessive in the time of seriously the flywheel safety misadventure can occur.
The utility model content
The utility model proposes a kind of full suspension disc brake back axle, it can avoid the situation of the flywheel that occurs owing to carrying force is excessive.
The technical solution of the utility model is achieved in that a kind of full suspension disc brake back axle, it comprises the axle housing of jackshaft and this jackshaft of parcel, also be provided with external rotary member and the disk brake that is connected at the two ends of described axle housing, one end of described external rotary member embeds and is arranged in the disk brake, the other end of described external rotary member is captiveed joint with the top ends of jackshaft by half axle bolt, is provided with bearing between described external rotary member and axle housing.
The beneficial effects of the utility model are: Action of Gravity Fields all during the vehicle heavy duty are on external rotary member, external rotary member is delivered to power on the axle housing by bearing, removed the load of jackshaft to load-carrying from, and the intensity of axle housing is far above jackshaft, it can bear the load-carrying of vehicle, jackshaft is only born the transmission load like this, has greatly prolonged the service life of jackshaft, has avoided the flywheel safety misadventure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is entirely the suspend structure cutaway view of disc brake back axle of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of full suspension disc brake back axle, it comprises the axle housing 2 of jackshaft 1 and this jackshaft 1 of parcel, also be provided with external rotary member 3 and the disk brake 4 that is connected at the two ends of described axle housing 2, one end of described external rotary member 3 embeds and is arranged in the disk brake 4, the other end of described external rotary member 3 is captiveed joint with the top ends of jackshaft 1 by half axle bolt 5, is provided with bearing at described external rotary member 3 and 2 of axle housings.
Action of Gravity Fields all during the vehicle heavy duty are on external rotary member 3, external rotary member 3 is delivered to power on the axle housing 2 by bearing, removed the load of 1 pair of load-carrying of jackshaft from, and the intensity of axle housing 2 is far above jackshaft 1, it can bear the load-carrying of vehicle, the transmission of 1 burden of jackshaft is loaded like this, has greatly prolonged the service life of jackshaft 1, has avoided the flywheel safety misadventure.
Further, described bearing comprises clutch shaft bearing 7 and the second bearing 8 that is inwardly set gradually by jackshaft 1 end, is provided with dividing busing 9 at described clutch shaft bearing 7 and 8 on the second bearing.Implement as a kind of selectivity, adopt single bearing, its load is larger, causes easily the damage of bearing, therefore, selects two bearings comparatively suitable.
For preventing silt, dust, aqueous vapor etc. in outer intrusion bearing, and the lubricating oil in the restriction bearing spills, therefore at the bearing arranged outside oil sealing of described the second bearing 8.
In external rotary member 3, also be provided be used to stopping the axially movable jump ring back-up ring 6 of described bearing, avoided bearing to run outward, prevented the tire flywheel.
The top of the axle housing 2 in described external rotary member 3 also is provided with slotted nut 10.Slotted nut 10 is used with screw rod eye bolt, spring cotter, behind fastening nut and the bolt, inserts spring cotter, can prevent relatively rotating between bolts and nuts, avoids getting loose.By slotted nut 10 is set, can further prevent the situation of tire flywheel.
Be provided with guar plate 11 at described disk brake 4 inner edges, avoid dust and sandy soil to enter between brake disc 4 and the brake plate, prolonged the service life of drg.
For making things convenient for the installation of drg, can being close to welded and installed support on the shell shell of guar plate 11, repeat no more here.
Adopt this full suspension disc brake back axle, can effectively reduce half axle fracture, the tire situation such as come off, even if in more extreme situation, the phenomenon that half axle fracture really occurs, such as cross-country or impact of superhigh intensity etc., vehicle also only can be lost part power because of half axle fracture, thus can't cause thus tire come off cause to lose control of one's vehicle, half bending shaft causes the grave accidents such as the excessive forfeiture driveability of vehicle tyre inclination, promoted the safety of vehicle.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
