Embodiment Construction

[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0014] Such as Figure 1 to Figure 2 As shown, the shifter 1 with variable-diameter drum springs includes a drum shaft 2, on which a shift drum array composed of shift drums 3 is arranged, and the adjacent shift drums 3 are respectively A shift spring 4 is provided, and the shift spring 4 includes a pair of tapered diameter-reducing spring bodies 41 connected by welding.

[0015] This shift spring 4 is made of stainless steel.

[0016] During use, the user sleeves the shift drum 3 and the shift spring 4 onto the drum shaft 2 , and makes the shift spring 4 stuck between the shift drums 3 . Since the variable diameter spring body 41 is conical, i...

Abstract

The invention discloses a gear shifter provided with diameter-variable drum springs. The gear shifter provided with the diameter-variable drum springs comprises a drum shaft, a gear shifting drum array composed of gear shifting drums is arranged on the drum shaft, and gear shifting springs are arranged between every two adjacent gear shafting drums. Each gear shifting spring comprises a pair of cone-shaped diameter-variable spring bodies which are connected with each other in a welded mode. The gear shifting springs are made of stainless steel. In the using process, a user makes the gear shifting drums and the gear shifting springs to be connected to the drum shaft in a sleeving mode, so that the gear shifting springs are clamped between the gear shifting drums. Because the diameter-variable spring bodies are in cone shapes, the diameter-variable spring bodies can be directly clamped at the centers of the gear shifting drums, decentration and displacement of the gear shifting springs can be prevented effectively, thus the gear shifting speed of the gear shifter is effectively improved, and the impact resistance is high. The gear shifter provided with the diameter-variable drum springs is simple in structure, obvious in effect, low in cost and high in practicality.

Description

technical field [0001] The invention relates to a beach car part, more precisely, a shifter with a variable-diameter drum spring. Background technique [0002] A fork-type shifter is usually provided on the ATV, and the shift fork is used to cooperate with the shift drum to achieve gear shifting. Usually, both the shift drum and the shift spring are arranged on the drum shaft. The existing shift spring is an equal-diameter spring, which is easily misaligned with the shift drum during the deformation process, resulting in a jerky shift feel. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a shifter with a variable-diameter drum spring. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A gear shifter with a reduced-diameter drum spring, characterized in that the gear shifter with a reduced-diameter drum spring includ...
