Large tractor link bearing structure

Abstract

The invention provides a large tractor link bearing structure. An inner link bearing and an outer link bearing are provided with grease through holes, oil nozzles communicate with the grease through holes, the grease through holes communicate with two grease discharging grooves, the inner link bearing and the outer link bearing have the grease discharging function, when grease inside the bearingsfails, the grease is convenient to replace, the friction coefficient is reduced, and the service life of the bearings is prolonged; a cover plate of the inner link bearing and a cover plate of the outer link bearing are screwed into shells through threads, locking grooves are formed in the outer diameter portions of the cover plates, thread locking is achieved through the locking grooves, and thenedge covering pressing is performed through a press machine; through the arrangement of the cover plates, ideal torque can be obtained, and meanwhile, thread looseness in the working process is prevented; an oil hole is formed in the shell of the inner link bearing of the large tractor link bearing structure, a spiral exhaust groove is formed in the outer surface of the shell, and when the greaseis added, the grease passes through the oil hole and the exhaust groove to lubricate of the outer diameter portion of the shell of the inner link bearing; and according to the large tractor link bearing structure, the problems of grease discharge, torque, abrasion and the like of the bearings are solved, the torque stability of the bearings is guaranteed, and meanwhile, the service life of the bearings is greatly prolonged.

Description

Technical field [0001] The invention belongs to the technical field of tie rod bearings, and specifically relates to a large tractor tie rod bearing structure. Background technique [0002] Large tractor tie rod bearings are used to connect the steering gear and the steering wheels of the vehicle chassis to ensure the safety of wheel steering. The suspension transmits force and moment between the frame and the axle (wheels), bears the load of the vehicle, and maintains the vehicle on the road. The normal driving on the vehicle is a key part of the independent suspension chassis steering system. It can make the wheelbase and front wheel positioning parameter changes within acceptable limits, ensuring that the vehicle has good driving stability. [0003] The existing tie rod steering bearings have the following problems: (1) due to the mud entering the bearing during the working process, the grease cannot be replaced when the grease is contaminated, resulting in serious wear of the ...
