Automobile power steering limiter

Abstract

The invention discloses an automobile power steering limiter. The automobile power steering limiter is characterized by comprising a ball (1), an outer ring (2), an inner ring (3) and a rubber support (6), wherein the exterior of the inner ring (3) is provided with an outer thread (7) with a rotating angle slightly smaller than a total angle from the maximum left rotation point to the maximum right rotation point of a steering wheel; the inner ring (3) is hollow and the inner diameter of the inner ring is slightly bigger than the outer diameter of a rotating shaft of the steering wheel; a key slot (5) is formed in the outer ring (2); one end of the external of the outer ring (2) is sleeved with the rubber support (6); the length of the inner ring (3) is greater than that of the outer ring (2); the inner ring (3) is movably sleeved inside the inner ring (2); the ball (1) is arranged for location fit between the outer thread of the inner ring (3) and the key slot of the outer ring (2); and a clamping ring (8) is arranged outside one end of the inner ring (3). The ball (1), the outer ring (2) and the inner ring (3) are made from steel. The automobile power steering limiter is simple in structure, reliable in performance and convenient to install; and on the premise that the other performance of the automobile is not affected, the limiter is capable of lowering the energy consumption of an automobile, prolonging the service life of spare parts of a mechanical hydraulic power steering system and enhancing the reliability of the mechanical hydraulic power steering system.

Description

(1) Technical field

[0001] The invention relates to an automobile power steering limiter. (2) Background technology

[0002] At present, the mechanical hydraulic power steering system of the car, when the steering wheel of the car is full, the internal pressure of the system will increase abnormally, which will not only increase the load on the engine, but also affect the service life of the hydraulic power steering system components. (3) Contents of the invention

[0003] The technical problem to be solved by the present invention is: in view of the above problems, provide an automobile power steering limiter with a mechanical limit protection device, which can limit the rotation angle of the steering wheel within a certain range, so that the steering wheel of the automobile will not be fully turned. .

[0004] The technical solution created by the present invention is: the automobile power steering limiter, which is characterized in that it includes a ball, an outer rin...
