Abstract
The utility model relates to a dust cover assembly of a knuckle bearing for a propelling rod, belonging to the field of automobile parts. A dust cover is fixedly connected with a baffle sheet and sleeved with a metal ball pin, the baffle sheet is in compression joint with a knuckle bearing outer ring which is rotatably connected with the metal ball pin, and the shell is sleeved with the knuckle bearing outer ring, the baffle sheet and the dust cover. The dust cover assembly has the advantages that the structure is novel, the dust cover and the baffle sheet are processed into an integer through a rubber adhering vulcanization technology, the sealing property is greatly improved, the installation space of the propelling rod is fully utilized, the structure of the baffle sheet and the dust cover is simplified, the cost of raw materials is reduced, the design space of a product is increased, the product property can be improved, and the service life of the propelling rod is prolonged by about 20-30 percent.
Description
Technical field
The utility model belongs to the auto parts and components production field, refers in particular to a kind of used component of track bar of heavy truck.
Background technique
The joint shaft bearing dust-proof cover that the heavy truck of now China's production uses with track bar, main catch and the dust-proof cover separate mode of adopting, owing to the track bar installing space is limited, and the structural limitations of separate mode, be bound to take a lot of spaces, increased again unnecessary seal clearance simultaneously.In Fig. 3, by oil seal spring 6 catch 2 and dust-proof cover 1 are fixed together.
Summary of the invention
The utility model provides the dust-proof cover assembly of a kind of track bar with joint shaft bearing, and to solve catch and dust-proof cover separate mode, it is large to take up room, and has increased the problem of seal clearance.
The technical solution of the utility model is: dust-proof cover is fixedly connected with catch, and dust-proof cover and Metal Ball guide connect, catch and the crimping of joint shaft bearing outer shroud, and joint shaft bearing outer shroud and metal ball pin are rotationally connected, housing and joint shaft bearing outer shroud, catch, dust-proof cover socket.
The utility model has the advantage of: novel structure, dust-proof cover and catch are in aggregates by the bonding sulfuration process processing of rubber, sealability improves greatly, take full advantage of the installing space of track bar, greatly simplified the structure of catch and dust-proof cover, the cost of raw material reduces, and has increased the design space of product, and can improve the performance of product, increase simultaneously about 20%-30% of track bar life-span.
