Abstract

The invention relates to a hinging assembly used for connecting a lower support of an EPS steering column with an instrument crossbeam. The hinging assembly is assembled in an installation hole of the lower support of the steering column in an interference manner and comprises a hinging shaft core, a sliding bearing and a hinging lining. A threaded through hole is formed in the middle portion of the hinging shaft core in the axial direction. A flange face is arranged at one end of the hinging shaft core and attached to the inner side face of the lower support of the steering column. The other end of the hinging shaft core is attached to the instrument crossbeam through a fastening bolt. The hinging shaft core is sleeved with the hinging lining. The sliding bearing is arranged between the hinging shaft core and the hinging lining. Compared with the prior art, the hinging assembly is compact in structure and high in practicality, the impact caused by the torque on the lower support and the instrument crossbeam in the reversing process is effectively reduced, and the hinging shaft core is prevented from rotating in the bolt driving process when the hinging assembly is installed.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and relates to a hinged assembly, in particular to a hinged assembly used to connect an EPS steering column lower bracket and an instrument beam. Background technique [0002] With the advancement of automobile technology, the development of the steering system has also experienced non-assisted steering system, hydraulic power steering system, and now the electric power steering system, English abbreviation EPS (ElectronicPowerSteering). At present, the non-assisted steering system has been eliminated, and the hydraulic power steering system and the electric power steering system are used more. However, the hydraulic power steering system uses hydraulic oil as the power source, which involves oil pipes, oil pumps, oil tanks and other parts. components, there are problems such as large number of parts, difficult installation and arrangement, low efficiency, and environmental po...
