The present invention discloses a low friction gear connection shaft for electric vehicle steering apparatuses. The low friction gear connection shaft comprises a shaft body and a gear body, wherein the shaft body and the gear body are movably connected through a threaded connection body, the shaft body is divided into three parts such as a left part, a middle part and a right part, the three parts are respectively a small gear tooth part, a position limiting disk and a large gear tooth part from left to right, an oil groove is arranged between the small gear tooth part and the position limiting disk, the position limiting disk and the large gear tooth part are provided with a gasket, the position limiting disk is an annular structure, one side surface outside the position limiting disk is provided with an anti-wear layer, the other side is provided with a reinforcing layer, the rear end of the shaft body is provided with the connection body for connecting the gear body, and the connection body is a threaded structure. According to the present invention, the structure is simple, the operation is easy, the friction and wear between the shaft body and other parts is reduced, the wear between the shaft body and the gear body and other parts is reduced through the gasket structure between the position limiting disk and the large gear tooth part, the service life of the shaft body is prolonged, and the shaft body and the gear body are firm and durable.
Description
Technical field
The present invention relates to gear assistance type automobile power steering device technical field of auxiliary equipment, specifically the low slip gear coupling shaft of a kind of electric automobile the steering gear.
Background technique
In electric boosted formula device, axle is a kind of common and mechanical connecting device that using scope is very wide, generally include bearing support and gear mass two parts, the effect of connection is played between bearing and gear, there is the axle construction of the various shape and structure such as square and circular, existing axis body top does not arrange back-up coat and friction resistant wearing layer, cause axle and gear and other joint parts fretting wear serious, connect not firm, Safety performance can not be guaranteed, and causes life of equipment short, maintenance cost to increase.
In order to well solve the problem, the invention provides the low slip gear coupling shaft of a kind of low electric automobile the steering gear.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: the low slip gear coupling shaft of a kind of electric automobile the steering gear, comprise axis body and gear mass, it is characterized in that: described axis body and gear mass are threaded connection body and are flexibly connected, described axis body is divided into three, left center right part, is respectively small gear teeth portion, position-arresting disk and gearwheel teeth portion from left to right.
The described low slip gear coupling shaft of a kind of electric automobile the steering gear, it is characterized in that: be provided with oil groove between described small gear teeth portion and position-arresting disk, described position-arresting disk and gearwheel teeth portion are provided with pad.
The described low slip gear coupling shaft of a kind of electric automobile the steering gear, comprises axis body and gear mass, it is characterized in that: described position-arresting disk is loop configuration, and its outer side surface is provided with scuff-resistant coating opposite side and is provided with back-up coat.
The described low slip gear coupling shaft of a kind of electric automobile the steering gear, comprises axis body and gear mass, it is characterized in that: described axis body rear end is provided with the connecting body connecting gear mass, and described connecting body is worm structure.
Beneficial effect of the present invention is:
1) structure of the present invention is simple, easy to operate, is easy to processing;
2) oil groove device between small gear teeth portion and position-arresting disk add two-layer between frictional force, reduce the friction and wear of axis body and other parts, gasket construction between position-arresting disk and gearwheel teeth portion alleviates the wearing and tearing of axis body and gear mass miscellaneous part, extend the working life of axis body, make axis body and gear mass more sturdy and durable
