Stop mark structure

Abstract

The invention relates to a shutdown gear structure. One side of a gear shifting hub on a gear shift mechanism is provided with a guide component; furthermore, a shutdown gear is arranged on a mainshaft corresponding to the guide component; a shutdown arm is arranged between the guide component and the shutdown gear; the middle of the shutdown arm is provided with a fixed hole seat; two sides the shutdown arm are respectively extended with a top-push end and a braking end; the brake end is provided with a convex column; the fixed hole seat can be passed through by a bolt column; wherein, the guide component is provided with a guideway; the guide rod of the top-push end is provided with a guide pin which can slide along the guideway of the guide component in order to lead the braking end ofthe shutdown arm to be ensured to enter positioning or be disconnected from the shutdown gear, thus reaching better gear advancing and gear backing effects.

Description

technical field [0001] The invention relates to a parking gear structure, in particular to a structure that can improve the smoothness of parking gear shifting. Background technique [0002] All-terrain vehicles1 such as figure 1 As shown, it mainly includes a frame unit 11, a steering mechanism 12, a front wheel 13, a seat portion 14, a rear wheel 15, and a power unit 2 that provides a power source for an all-terrain vehicle. The front of the vehicle frame 11 is pivotally connected to the steering mechanism 12, and a group of front wheels 13 are arranged below the steering mechanism 12. Behind the steering mechanism 12, a riding portion 14 is arranged on the vehicle frame unit 11. Below the riding portion 14 is power unit 2. The power unit 2, see figure 2 As shown, at least include an engine system 21, and a continuously variable transmission system 22 driven by the engine system 21, the continuously variable transmission system 22 drives the rear wheel shaft 24 by mean...

Problems solved by technology

Although the above-mentioned known parking gear mechanism can achieve the purpose of parking stability, there are still serious deficiencies in the known parking mechanism, such as Figure 8 As shown, when the protruding post 41 is pushed up by the cam 323, the protruding post 42 at the other end will move downward, but the downward movement of the protruding post 42 cannot properly make the protruding post 42 engage in the parking gear 347. In the tooth valley 347a of the parking gear 347, the protrusion 42 just abuts on the tooth peak 347b of the parking gear 347, and the main shaft 34 must be rotated by an angle before the protrusion 42 can be smoothly embedded in the tooth valley 347a of the parking gear 347. In order to achieve the purpose of parking stability, as mentioned above, when the boss 41 is pushed up by the cam 323, the boss 42 is forced to move down, but the boss 42 cannot move down, and the top is stuck on the parking gear 347 This situation makes it very difficult to shift gears. What's more, one end of the parking arm 4 is forced to be pushed by the cam 323, but the other end cannot move down. This situation easily causes the parking arm 4 to move downward. damage to
