Abstract
The utility model relates to a special drum -type rear axle of school bus, including the axle housing, the axle housing both ends are provided with drum brake respectively, and the drum brake outside is provided with the hub, and the middle part of axle housing sets up the reduction gear, the axle housing on be provided with the air chamber support, the air chamber support supports the air chamber, the air chamber passes through the cylinder with drum brake to be connected, the distance between outside two hubs is 1686mm. The utility model discloses a design one set of dedicated rear axle system of school bus that the width is narrower, this rear axle system adopts drum brake, drum brake braking effect is favorable to improving school bus safety well, for practicing thrift the space, reduce the rear axle width, on designing the axle housing with drum brake's air chamber support, it reaches reduction school bus width mesh to reduce drum brake overall dimension, the school bus can go in country road or city narrow lane, make things convenient for the student to take, the biggest outer wide only 1686mm of whole bridge, track 1430mm, whole school bus is outer wide no longer than 1 meter 9, and the trafficability characteristic strengthens greatly.
Description
technical field:
The utility model relates to the special parts technical field of school bus, is specifically related to the special drum-type back axle of a kind of school bus.
background technology:
Along with the raising of people's awareness of safety, the attention of people to safety of student also improves gradually, is specifically designed to the school bus that student takes, arises at the historic moment.But, school bus on existing market is convert from some old money passenger vehicles mostly, or directly old money vehicle is used as school bus use, and its partial function can not meet the needs of school bus, and cost is higher, school bus mainly for passenger be child, safety be topmost, also require traveling comfort in addition, on this basis, reduce productive costs as much as possible, the most floor of existing school bus is higher, and inconvenient child takes.Existing school bus substantially width is all wider, and passenger vehicle width is basically identical, in some rural highways or urban streets and lanes because road is narrower, not easily passes through.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides the special drum-type back axle of a kind of school bus, it designs the special rear bridge system of the narrower school bus of a set of width, this rear bridge system adopts drum brake mechanism, drum brake mechanism good braking effect, braking steadily, be conducive to improving safety of school bus, simultaneously, for conserve space, reduce back axle width, the air chamber support of drum brake mechanism is designed on axle housing, again reduce the oad of drum brake mechanism, back axle width is reduced to reach, and then reach the object reducing school bus width, school bus is travelled in the narrow lane of rural highway or city, student is facilitated to take.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The special drum-type back axle of a kind of school bus, wherein: comprise axle housing, wheel hub, retarder, drum brake mechanism, air chamber and air chamber support, axle housing two ends are respectively arranged with drum brake mechanism, drum brake mechanism arranged outside has wheel hub, the middle part of axle housing arranges retarder, described axle housing is provided with air chamber support, and air chamber support supports air chamber, and air chamber is connected by cylinder with drum brake mechanism.
Further, the distance between outside two wheel hubs of described axle housing both sides is 1686mm.
Further, the oad of described drum brake mechanism is φ 300*130mm.
The beneficial effects of the utility model are:
1, the utility model designs the special rear bridge system of the narrower school bus of a set of width, this rear bridge system adopts drum brake mechanism, drum brake mechanism good braking effect, braking steadily, be conducive to improving safety of school bus, simultaneously, for conserve space, reduce back axle width, the air chamber support of drum brake mechanism is designed on axle housing, again reduce the oad of drum brake mechanism, back axle width is reduced to reach, and then reach the object reducing school bus width, school bus is travelled in the narrow lane of rural highway or city, student is facilitated to take, the maximum outer wide only 1686mm of whole bridge of the present utility model, wheelspan 1430mm, whole school bus is wide is outward no more than 1 meter 9, and crossing ability strengthens greatly.
2, the utility model structure is simple, easy to use; Width is little, highly low, lightweight.Can greatly improve car load traveling comfort and fuel economy.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic top plan view of the utility model Fig. 1;
Fig. 3 is that schematic diagram is looked on a left side of the utility model Fig. 1.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the special drum-type back axle of a kind of school bus, comprise axle housing 1, wheel hub 2, retarder 3, drum brake mechanism 4, air chamber 5 and air chamber support 6, axle housing 1 two ends are respectively arranged with drum brake mechanism 4, drum brake mechanism 4 arranged outside has wheel hub 2, distance between outside two wheel hubs 2 is 1686mm, drum brake mechanism 4 oad is for being φ 300*130mm, the middle part of axle housing 1 arranges retarder 3, described axle housing 1 is provided with air chamber support 6, air chamber support 6 supports air chamber 5, and air chamber 5 is connected by cylinder with drum brake mechanism 4.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
