Background technology
Mine vehicle hangs structures such as adopting hydro-pneumatic spring, BF or inflating rubber spring suspension, occupy than large space on its vehicle frame of being everlasting, and the available space, particularly sub-terrain mines that have reduced the whole vehicle size thus are subjected to the underworkings dimensional restriction with the vehicle structure size.
The utility model content
The purpose of this utility model is to provide transport vehicle oleo-pneumatic suspension system under a kind of coal mine, solves existing mine vehicle and is suspended on and occupies than large space on the vehicle frame, be subjected to problem such as underworkings dimensional restriction.
The technical solution of the utility model is:
Transport vehicle oleo-pneumatic suspension system under a kind of coal mine, this oleo-pneumatic suspension system is the four-bar linkage of hydro-pneumatic spring suspension cylinder, triangle rocking arm, connecting rod, cantilever shalving formation, the piston rod of hydro-pneumatic spring suspension cylinder and triangle rocking arm one end are hinged, the triangle rocking arm other end and connecting rod one end are hinged, and the connecting rod other end and cantilever shalving one end are hinged.
Transport vehicle oleo-pneumatic suspension system under the described coal mine, this oleo-pneumatic suspension system is installed on the vehicle frame as the independent suspension structure of single wheel; Hydro-pneumatic spring suspension cylinder horizontal arrangement is above wheel, and the triangle rocking arm other end is hinged with the connecting rod that is arranged in wheel one side, and the cantilever shalving other end is hinged on wheel opposite side bottom of frame, and the cantilever shalving middle part firmly is connected with the vehicle bridge axle housing.
Transport vehicle oleo-pneumatic suspension system under the described coal mine, vehicle frame both sides, wheel top are provided with the double-arch type crossbeam, and hydro-pneumatic spring suspension cylinder, triangle rocking arm, connecting rod are located in the middle of the double-arch type crossbeam, and triangle rocking arm middle-end and double-arch type crossbeam are hinged.
The beneficial effects of the utility model are:
1, the utility model keystone configuration is the four-bar linkage that hydro-pneumatic spring suspension cylinder-triangle rocking arm-connecting rod-cantilever shalving constitutes hydro-pneumatic spring suspension cylinder horizontal arrangement, is used for the independent suspension structure of single wheel.
2, the utility model is used on the mine vehicle, each wheel independent suspension, hydro-pneumatic spring suspension cylinder-triangle rocking arm-linkage arrangement in the independent suspension structure is between the double-arch type crossbeam, the double-arch type crossbeam is arranged in wheel gabarit outside (wheel top) as the part of vehicle frame, hangs reliable, compact conformation, do not occupy the available space between two wheels,, provide technical guarantee for making full use of the space between two wheels.Along with beating of wheel, the cantilever shalving drivening rod that links to each other with the vehicle bridge axle housing promotes rocking arm and rotates, thereby makes the action of hydro-pneumatic spring cylinder piston rod, realizes the resilient suspension of each wheel, reaches the purpose to Vehicle damper.
3, the utility model cantilever shalving one end and connecting rod are hinged, and the other end and vehicle frame, crossbeam are hinged, and its middle part firmly links to each other with the vehicle bridge axle housing, and along with beating of wheel, the cantilever shalving drivening rod also promotes the rotation of triangle rocking arm.Thereby, make the action of hydro-pneumatic spring cylinder piston rod, realize the resilient suspension of each wheel.
