Description
Technical field
The present invention relates to road sweeper field, particularly relate to road sweeper round brush cylinder and stop buffer.
Background technology
At present, the round brush cylinder on road sweeper drives round brush cylinder to rotate by the output shaft of gearbox by chain-drive mechanism, thus realize ground surface round brush and cleaning.Road sweeper, in the process of cleaning, needs to stop unavoidably.When road sweeper stops, drive sprocket is in static, and there is the inertia operated forward in round brush cylinder, therefore be there is by movable sprocket the trend rotated forward, thus the output shaft of drive sprocket and gearbox is impacted by chain, be subject to such impact for a long time, chain, drive sprocket and output shaft of gear-box all easily produce damage.
Summary of the invention
A kind of structure simple road sweeper round brush cylinder is the object of the present invention is to provide to stop buffer, the impact force that this round brush cylinder produces when stopping buffer road sweeper being braked cushions, and improves the application life of chain-drive mechanism and the output shaft of gear-box driving round brush cylinder to rotate.
For achieving the above object, the present invention is by the following technical solutions:
Road sweeper round brush cylinder stops buffer, comprise vehicle frame, round brush cylinder and chain-drive mechanism, described round brush cylinder is located on vehicle frame, described chain-drive mechanism comprises drive sprocket, by movable sprocket and chain, chain is connected with drive sprocket and passive sprocket engagement respectively, described drive sprocket is located on the output shaft of road sweeper gearbox, describedly be connected on the axle head of round brush cylinder by movable sprocket by clutch, described clutch comprises driving disc spacing pressing and the driven disc of mutual clamping, and described driven disc fixed cover is located on the axle head of round brush cylinder, described driving disc spacing pressing is fixedly connected to form one with by an axial end of movable sprocket, and be movably set on the axle head of round brush cylinder, described driving disc spacing pressing on the axial end of driven disc along the circumferential direction uniform intervals have multiple first fixture block, the axial end of the first fixture block is the slope along the circumferential direction progressively tilted, described driven disc corresponding each first fixture block on the axial end of driving disc spacing pressing is respectively equipped with the second fixture block, the axial end of the second fixture block is the slope along the circumferential direction progressively tilted, the mutual clamping of stub end of stub end second fixture block corresponding to it of described first fixture block, the axle head end of described round brush cylinder is fixedly connected with stationary gland, described stationary gland and be provided with Compress Spring by between movable sprocket.
Described round brush cylinder stops buffer also comprising sleeve, bounce cylinder and intermediate chain wheel, be fixed on bottom described bounce cylinder on vehicle frame, described jacket casing is located on the piston rod of bounce cylinder, the top of sleeve is provided with bearing, described intermediate chain wheel is located on bearing, and intermediate chain wheel and chain are connected with a joggle.
Described driven disc is provided with axle sleeve integrated with it, and described driven disc is located at the axle head of round brush cylinder by axle sleeve fixed cover.
Describedly to be movably set on the axle head of round brush cylinder by the first rolling bearing by the centre bore of movable sprocket.
The centre bore of described stationary gland is provided with the second rolling bearing, and the endoporus of described second rolling bearing is arranged with sleeve, and the inner hole thread of described sleeve is connected with set bolt, and set bolt is threaded with the axle head of round brush cylinder again.
The present invention adopts above technical scheme, compress spring top pressure driving disc spacing pressing under normal state, the mutual clamping of the second fixture block of the first fixture block on driving disc spacing pressing and driven disc, driving disc spacing pressing rotates under by the drive of movable sprocket, driving disc spacing pressing drives driven disc to rotate again, thus drives round brush cylinder to rotate.
When road sweeper stops in traveling process, drive sprocket, chain and all stopped driven by movable sprocket, and driving disc spacing pressing also stops operating, and round brush cylinder continues because there is inertia force to rotate, now, driven disc continues to rotate with chasing after round brush cylinder, in rotary course, on driven disc, the stub end of the second fixture block is separated with the stub end of the first fixture block, after driven disc turns over certain angle, the slope of the second fixture block moves along the slope of the first fixture block, and outside pushing tow first fixture block, thus by outside for driving disc spacing pressing pushing tow to being separated with driven disc, Compress Spring is extruded while driving disc spacing pressing outwards moves, when the slope of the second fixture block is separated with the slope of the first fixture block, driving disc spacing pressing by pushing tow to outermost end, then under the rebound effect of Compress Spring, driving disc spacing pressing is return again, said process is until the rotational energy of round brush cylinder is consumed totally repeatedly, thus the impact force produced when being stopped by cylinder cushions.
In addition, continue because of round brush cylinder inertia force to rotate and the impact force that produces can press down intermediate chain wheel by chain, and be sequentially finally passed to bounce cylinder by supporting seat, sleeve, bounce cylinder is subject to downforce, then downforce is carried out cushioning and discharging.
To sum up, the present invention not only structure is simple, and effectively can avoid the impact because being subject to when road sweeper stops of chain, drive sprocket and output shaft of gear-box, thus can application life of raising chain-drive mechanism effectively and output shaft of gear-box.
