Description
Technical field
The present invention relates to new energy sanitation equipment field more particularly to a kind of bearings with graphite copper sheathing, radial type vehicle
Frame and sweeper.
Background technique
Currently, on the market common vacuum suction type ground sweeper generally have for along ground run wheel and
At least one is used to clean the cleaning brush and vacuum waste case of the pivotable drive on ground.It can by means of this ground sweeper
To clean ground, such as street, pavement or parking lot etc..At least one cleaning brush of ground sweeper acts on to be cleaned
Ground on, and have and cleaning material be directed to Acetabula device, cleaning material is sucked through connected to it by Acetabula device
Pipeline is transported in vacuum waste case.
Wherein, since the sweeper of existing vehicle type generally uses Integral frame structure, vacuum waste case be can be set
In the region at the rear portion of vehicle frame, and vehicle can have driver cabin in region in front.By sweep device, suction nozzle group
Part is arranged in front of the driving direction of vehicle frame, therefore must use the stronger vehicle frame of larger and bearing capacity, just leads to this in this way
Kind unitized frame, which goes out, turns now to inconvenience, and walking cleaning is not flexible, and unitized frame road pavement situation adaptibility to response is poor, causes to sweep the floor
It is undesirable that performance is swept in the suction of machine.
In order to improve the flexibility of scavenging machine, therefore a kind of vehicle frame of radial type is developed, is between front frame and Rear frame
It is connected by bearing, lateral impact forces when not only being turned to due to vehicle frame, and also will receive longitudinal impact force, therefore in bearing
There are many different bearings for interior setting, are converted by power between different bearings, and impact force is converted and absorbed, this also leads to bearing knot
Structure is complicated, maintenance difficult.
Summary of the invention
The first object of the present invention is to provide a kind of bearing with graphite copper sheathing of reliable self-lubricating.

Plane bearing and end cap is respectively set to end, so that the bearing arrangement of this case is simple.
Further scheme is to be connected between axle sleeve and connecting shaft to graphite copper sheathing clearance fit.
Further scheme is, the first axis end of the first plane bearing and axle sleeve, graphite copper sheathing first axis end
It is adjacent.
Further scheme is that axle sleeve is provided with the first land, the end face of the first land and first at first axis end
Plane bearing is adjacent.
Further scheme is the inner face of first end cover and the first plane bearing clearance fit, first end cover and the
The lateral surface of one land connects.
Therefore utilize the clearance fit of each device and the neighbour of the first plane bearing and axle sleeve, graphite copper sheathing
It connects and positioning of the end cap to plane bearing, longitudinal impact force can be converted by plane bearing, not only device layout is compact, and
Be conducive to improve the load-carrying properties of bearing.
Further scheme is that graphite copper sheathing includes copper sheathing and multiple graphite blocks, and the outer wall of copper sheathing is provided with multiple peaces
Hole is filled, graphite block is mounted in mounting hole.
Further scheme is that channel is provided in connecting shaft, and first opening in channel is located on the peripheral wall of connecting shaft
And be located in axle sleeve, second opening in channel is located on the axial end portion of connecting shaft.
Therefore graphite copper sheathing is good with load, wear-resisting property is good, it is suitable for the high rotation fortune carried under low speed
Dynamic, oscillating motion and often opening and closing is frequent and be not easy to form the occasion of hydrodynamic lubrication under loads, in condition of boundary lubrication
Under can long-term non-refuelling maintenance, and refueling in crossing layer makes bearing the service life is longer, therefore can carry out filling lubrication by channel
Oil, without opening end cap or tearing bearing open.
In order to realize that the second object of the present invention, the present invention provide a kind of articulated frame, including the first vehicle frame, the second vehicle
Frame and bearing, the bearing of bearing using the above scheme, the first vehicle frame are connect with axle sleeve, the second vehicle frame with connect axis connection.
Further scheme is that the second vehicle frame is provided with the first connecting plate and the second connecting plate, the setting of the first connecting plate
There is a first positioning hole, the second connecting plate is provided with second location hole, and connecting shaft passes through first positioning hole and second location hole, and first
Connecting plate is located at the axially external of first end cover, and the second connecting plate is located at the axially external of second end cover；Connecting shaft is in two axis
It is respectively arranged with the first fixed part and the second fixed part to end, for the first fixed part for fixing the first connecting plate, second is fixed
Portion is for fixing the second connecting plate.
In order to realize that the third object of the present invention, the present invention provide a kind of sweeper, including articulated frame and brush, cut with scissors
It connects and is provided with wheel on formula vehicle frame, brush is arranged on articulated frame, which is characterized in that articulated frame is using the above scheme
Articulated frame.
Therefore be connected between connecting shaft and axle sleeve by graphite copper sheathing and the first vehicle frame is connect with axle sleeve, and
Second vehicle frame setting location hole with connect axis connection, connecting shaft is effectively reduced in the self-lubricating function having using graphite copper sheathing
Friction, while graphite copper sheathing have efficient heating conduction, and two axial end portions be arranged respectively plane bearing and
End cap, so that the bearing arrangement of this case is simple, when maintenance, which only needs to open end cap, to carry out plane bearing or graphite copper sheathing
Replacement, using only configuration graphite copper sheathing is lubricated in axle sleeve, therefore the vehicle frame of this case and road sweeper are not only simple in structure and safeguard
It is easy.
