Abstract
A brake forced cooling device is characterized in that an oil discharge hole is formed in an axle package at the position of a speed reducer roller bearing, an oil feed hole is formed in a lateral side bearing shaft, the oil feed hole is communicated with a hub inner cavity through an oil pipeline, the oil discharge hole in the axle package is communicated with an oil inlet of an oil pump, the oil feed hole in the lateral side bearing shaft is communicated with an oil outlet of the oil pump, oil liquid inside the axle package is sucked out through the oil pump from the oil discharge hole, the oil liquid is then sent into hubs through the oil pump from the oil feed hole, the oil inlet of the oil pump is communicated with the axle package, and the central horizontal height of the oil discharge hole formed in the axle package is not lower than the horizontal height of the lowest roller axis in a differential mechanism roller bearing. The brake forced cooling device has the advantages of being simple in structure, low in cost, and small in occupied space. Moreover, the temperature of the ridge package is improved and the temperature of a brake is reduced through the oil liquid circulation of the axle package and the hubs so as to increase the heat-dissipating speed of a humidification-type bridge and prevent the brake from being damaged because of high temperature.
Description
Technical field
The utility model relates to the device that in a kind of construction machinery and equipment the wet type bridge dispelled the heat, particularly relates to a kind of to wet type bridge drg forced cooling device.
Background technology
The heat that the braking of wheel type loader complete machine produces, major part concentrates on driving-axle brake.When load is heavy, the speed of a motor vehicle is high, braking is frequent, long-time continuous firing, cause easily drg high temperature and cause damage.
The wet type bridge of present domestic wheel type loader configuration is most of without the active cooling mechanism, and minority adopts the loader of external cooling system, need consider the radiator arrangement space again.
The utility model content
The purpose of this utility model just provide a kind of simple in structure, cost is low, it is little to occupy the space, oil circulation by bridge bag and wheel hub, improve bridge bag temperature, reduce brake temperature and increase wet type bridge radiating rate, prevent drg high temperature and cause the drg forced cooling device of damage.
Solution of the present utility model is such: the utility model comprises Qiao Bao and two side bolsters, and the position that described bridge bag is positioned at the retarder coro bearng has oil outlet; Have fuel feed hole at described side bolster, described fuel feed hole is communicated with the wheel hub inner chamber by the oil pipe road; Oil outlet that described bridge is wrapped is communicated with the oil inlet of oil pump, and the fuel feed hole on the described side bolster is communicated with the oil outlet of oil pump, by oil pump with the fluid in the bridge bag from the oil outlet sucking-off, by oil pump fluid is sent in the wheel hub from fuel feed hole again.
Further: the oil inlet of described oil pump is provided with oil absorption filter with the oil circuit that is communicated with of bridge bag.
Further: the inboard, oil outlet place at described bridge bag is provided with filtering net.
Further: the oil outlet central horizontal height that described bridge is wrapped out is not less than the level height of minimum roller axis in the diff coro bearng.
The utility model has the advantages that simple in structure, cost is low, it is little to occupy the space, by the oil circulation of bridge bag and wheel hub, improves bridge bag temperature, reduces brake temperature and increase wet type bridge radiating rate, prevent drg high temperature and cause damage.
