Quick release structure of steering wheel

Abstract

The invention provides a quick release structure of a steering wheel for effectively preventing the abrasion of an inner ring and an outer ring, guaranteeing the stability of relative positions of the outer ring and the inner ring, preventing relative rotating displacements of the inner ring and the outer ring, guaranteeing the rotating stability of the steering wheel and preventing unnecessary accidents. The quick release structure comprises the outer ring and the inner ring, wherein the outer ring is provided with a push rod accommodating groove at the axial eccentric position, the push rod accommodating grooving intersecting the axis; the push rod accommodating groove is communicated with an inner hole of the outer ring; a push rod is mounted in the push rod accommodating groove and is provided with a yielding groove corresponding to the inner ring; and a positioning groove fitting the push rod is formed in the outer side of the inner ring. The quick release structure is characterized in that the inner wall of the outer ring is polygonal in shape; and the outer wall of the inner ring fits the inner wall of the outer ring.

Description

Technical field [0001] The invention relates to the technical field of racing car component structures, in particular to a steering wheel quick release structure. Background technique [0002] Due to racing, it is subject to competition rules and other restrictions. The cab of the racing car is very compact, and its cab space is very limited. Under a series of restrictions, the steering wheel of the racing car can only be made detachable, and the driver is entering and exiting. When in the cab, first remove the steering wheel, install the steering wheel after the driver is seated firmly, remove the steering wheel when leaving the cab, and leave enough cab space to ensure that the driver can leave quickly and ensure the driver Escape quickly in an emergency. [0003] The quick release structure of the steering wheel realizes the connection with the rotating shaft when the steering wheel is installed during driving, which satisfies the driver's control of the racing direction. When ...

Problems solved by technology

The existing steering wheel quick-release structure, such as the Chinese utility model patent No. ZL2012202691369, the inner wall of the outer ring and the outer wall of the inner ring are connected by mutual involute splines, and the torque is transmitted through the involute splines. Due to the frequency of rotation and the large torsion force generated during the rotation, the involute splines will wear out, causing relative rotational displacement between the outer ring and the inner ring, which affects the stability of the steering wheel rotation. cause an accident
