Description
Technical field
The utility model belongs to steering track rod system field, is specifically related to a kind of intermediate rockers locking mechanism.
Background technology
In recent years, along with the construction of express highway, the trend that transport enterprise has the load carrying ability making heavy motor vehicle to increase gradually to improve conveying efficiency.In order to alleviate axle load, improve driving safety and stability, heavy motor vehicle gradually adopts Double front axle steering mechanism.
Double front axle steering mechanism comprises bearing circle, steering transmission linkage, deflector, drag link, intermediate rod and intermediate rockers assembly etc., and the drag link of the first bridge with the second bridge is mainly connected by intermediate rockers, thus realizes the first bridge, synchronously the turning to of the second bridge.
Existing intermediate rockers assembly comprises base, rocking arm and rocker shaft etc., and wherein rocking arm rotates around rocker shaft, particularly in rocking arm rotation place, bears larger moment of flexure, causes rocking arm easily to damage.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide one can make rocking arm and bearing pin common rotation, can bear the intermediate rockers locking mechanism of larger moment of flexure.
For achieving the above object, the technical solution of the utility model is: intermediate rockers locking mechanism, comprise rocking arm and bearing pin, described one end is provided with the through hole coordinating bearing pin to insert, wherein, be provided with from rocking arm side and communicate with through hole, and from the pin-and-hole that opposite side passes, pin-and-hole one end is provided with the locking boss be positioned on rocking arm, the externally threaded locking pin of one end band is plugged in described pin-and-hole, the threaded one end of locking pin is stretched out from locking boss, and is locked by jam nut, and described bearing pin is provided with the groove or hole that lock pin.
When adopting technique scheme, bearing pin inserts in the through hole of one end; rocking arm side is provided with pin-and-hole, is inserted with the externally threaded locking pin of one end band, in addition in pin-and-hole; bearing pin is provided with the groove or hole that lock pin; so insert in pin-and-hole by locking pin, then by tightening jam nut, and rocking arm just can be made relative with bearing pin fixing; in the process that rocking arm swings, bearing pin just can be driven to swing together.The utility model is inserted in pin-and-hole by locking pin and locks, thus rocking arm and bearing pin one are swung, and at this moment, moment of flexure is mainly on bearing pin, and rocking arm rotates the moment of flexure of bearing in place and greatly reduces, and rocking arm is not easy to damage.
Further, described locking pin side is provided with locking face, and bearing pin side is provided with the groove coordinated with described locking face.After the locking nut screwing of locking pin one end, the locking face of locking pin side is engaged with the groove of bearing pin side, and both contact surface is comparatively large, when rocking arm swings, and the uniform force on locking pin and bearing pin contact surface.
Further, be provided with spring washer and flat gasket successively inside described jam nut, described flat gasket offsets with locking boss.Be provided with spring washer and flat gasket to compensate the accuracy of manufacture of bearing pin and the wearing and tearing in using.
Further, described locking pin is column, and locking pin changes from small to big from threaded one end towards other end diameter, and described bearing pin is provided with hole, and described pin-and-hole and hole coordinate with locking pin.After the locking nut screwing of locking pin one end, because locking pin changes from small to big from threaded one end towards other end diameter, so locking pin swelling can be relied on, thus make rocking arm relative with bearing pin fixing.
