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
The invention relates to a kind of automobile power steering limiting device.
(2) background technology
The mechanical type hydraulic power steering system that present automobile is disposed, when vehicle steering was made, internal system pressure can raise unusually, has both increased the load of driving engine thus, will influence the service life of hydraulic power steering system parts again.
(3) summary of the invention
The technical matters that the invention will solve is: at the problems referred to above, provide a kind of automobile power steering limiting device with the mechanical position limitation fender guard, can make vehicle steering be unlikely to make the restriction of the rotational angle of bearing circle within the specific limits.
The technical scheme of the invention is: the automobile power steering limiting device, it is characterized in that, comprise ball, the outer ring, inner ring, rubber standoff, the outside of inner ring has one section anglec of rotation to be slightly less than the outside thread of making total angle about vehicle steering, inner ring hollow, its internal diameter is slightly larger than bearing circle turning cylinder external diameter, there is a keyway inside of outer ring, outside one end of outer ring is set with rubber standoff, the length of inner ring is greater than the outer ring, and the inner ring movable set is in the inside of outer ring, has a ball to position between inner ring outside thread and outer ring keyway and cooperates, it is fixing that chucking circle 8 is equipped with in the one end outside of inner ring, and the material of body is steel.
The invention need not change vehicle structure, as long as the invention, is sleeved on the vehicle steering turning cylinder, and inner ring and vehicle steering turning cylinder are fixed with holding screw, and outer coil support and vehicle body bolt just can realize the position limitation protection effect.
The invention is simple in structure, and dependable performance is easy for installation, under the prerequisite that does not influence other performance of automobile, reduce the automobile energy consumption, prolonged the service life of mechanical type hydraulic power steering system parts, improved the reliability of mechanical type hydraulic power steering system.
(4) description of drawings
Accompanying drawing 1 is the main TV structure scheme drawing of the invention.
(5) specific embodiment
A kind of automobile power steering limiting device; it is characterized in that; comprise ball 1; outer ring 2; inner ring 3; rubber standoff 6; the outside of inner ring 3 has one section anglec of rotation to be slightly less than the outside thread 7 of making total angle about vehicle steering; inner ring 3 hollows; its internal diameter is slightly larger than bearing circle turning cylinder external diameter; there is a keyway 5 inside of outer ring 2; outside one end of outer ring 2 is set with rubber standoff 6; the length of inner ring 3 is greater than outer ring 2; inner ring 3 movable sets are 2 inside in the outer ring; have a ball 1 to position between inner ring 3 outside threads and outer ring 2 keyways and cooperate, it is fixing that chucking circle 8 is equipped with in the end outside of inner ring 3, and the material of body is steel; the invention need not change vehicle structure; as long as the invention, be sleeved on the vehicle steering turning cylinder, inner ring 3 is fixing with holding screw 4 with the vehicle steering turning cylinder; outer ring 2 supports and vehicle body are fixing with bolt 4, just can realize the position limitation protection effect.The invention, simple in structure, dependable performance, easy for installation, under the prerequisite that does not influence other performance of automobile, reduced the automobile energy consumption, prolong the service life of mechanical type hydraulic power steering system parts, improved the reliability of mechanical type hydraulic power steering system.
Claims (2)
