Abstract
The utility model relates to a low -floor bus wheelhub reductor for axle, including wheelhub reductor, gear train for the wheel reduction install in the wheel reduction casing, wheelhub reductor's upper portion be provided with the boss, set up horizontally U type groove in the boss, the opening direction in U type groove is perpendicular with wheel reduction's axis, U type groove both sides set up the screw hole. The utility model discloses a with low -floor bus support bridge's last distance rod support integration to the wheelhub reductor, traditional last distance rod support has been cancelled, boss in a U type of wheelhub reductor upper portion increase, set up on the boss and be used for connecting the screw hole of going up the distance rod, realize the integral structure of wheelhub reductor and last distance rod support, be favorable to automobile parts's lightweight integrative development, reduce the spare part quantity of low -floor bus, be convenient for automobile parts's management and transportation, reduces the production cost.
Description
technical field:
The utility model belongs to bus component structural technical field, is specifically related to a kind of low-floor bus wheel-side speed reducer for axle housing.
background technique:
Along with China's public transport operating mode is improved day by day, upper inferior requirement promotes day by day fast, and public transport travelling comfort demand increases day by day, and low-floor public transport is arisen at the historic moment as the leading vehicle of bus rapid transit.Low-floor bus requires that the floor of bus is low as much as possible, in order to facilitate the upper and lower bus of passenger, for reaching the object reducing public bus floor, technician develops a kind of bus vehicle bridge of low-floor, it connects a wheel reductor respectively at axle housing two ends, in the bilateral symmetry of wheel reductor housing, two L-type cantilevers are set, two L-type cantilevers and wheel reductor housing form the bracket of novel C type structure, thus upgrade existing bus axle carrier and superpose mounting structure up and down with axle housing, reach the object reducing public bus floor.But wheel reductor housing and the upper traction bar support of this novel bus low-floor vehicle bridge are Split type structures, as shown in Figure 1, wheel reductor housing 101 and upper traction bar support 102 are bolted connection.
Along with the development of auto technology, the requirement of auto parts and components lightweight, integration is progressively improving, automobile production enterprise all reduces amount of parts in pursuit, save production and the administration cost of component, but wheel reductor housing and the upper traction bar support Split type structure of novel bus low-floor vehicle bridge obviously can not meet the integrated requirement of component lightweight of automobile industry.
model utility content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of low-floor bus wheel-side speed reducer for axle housing, it is integrated on wheel reductor housing by the upper traction bar support of low-floor bus supporting bridge, eliminate traditional upper traction bar support, a U-shaped boss is increased on wheel reductor housing top, boss is arranged the tapped hole for connecting upper thrust rod, realize the integral structure of wheel reductor housing and upper traction bar support, be conducive to the lightweight integrative development of auto parts and components, reduce the amount of parts of low-floor bus, be convenient to management and the transport of auto parts and components, reduce cost of production.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of low-floor bus wheel-side speed reducer for axle housing, wherein: comprise wheel reductor housing, described wheel reductor gear train is arranged in wheel reductor housing, the top of described wheel reductor housing is provided with boss, the U-type groove of level is set in boss, the opening direction of U-type groove and the axes normal of wheel reductor, U-type groove both sides arrange tapped hole.
Further, described wheel reductor housing and boss are structure as a whole.
The beneficial effects of the utility model are:
The utility model is integrated on wheel reductor housing by the upper traction bar support of low-floor bus supporting bridge, eliminate traditional upper traction bar support, a U-shaped boss is increased on wheel reductor housing top, boss is arranged the tapped hole for connecting upper thrust rod, realize the integral structure of wheel reductor housing and upper traction bar support, be conducive to the lightweight integrative development of auto parts and components, reduce the amount of parts of low-floor bus, be convenient to management and the transport of auto parts and components, reduce cost of production.
accompanying drawing illustrates:
Fig. 1 is existing axle housing and wheel reductor shell construction schematic diagram;
Fig. 2 is the utility model structural representation.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of low-floor bus wheel-side speed reducer for axle housing,: comprise wheel reductor housing 1, described wheel reductor gear train is arranged in wheel reductor housing 1, and the top of described wheel reductor housing 1 is provided with boss 2, and described wheel reductor housing 1 is structure as a whole with boss 2, casting forms together, arrange the U-type groove 3 of level in boss 2, the opening direction of U-type groove 3 and the axes normal of wheel reductor, U-type groove 3 both sides arrange tapped hole 4.
During use, the gear train needed for the wheel reductor of bus is arranged in wheel reductor housing 1, then one end of upper thrust rod is put in U-type groove 3 of the present utility model, and by bolt, upper thrust rod and boss 2 are fastenedly connected.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art ordinary skill people 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.
