Problems solved by technology

On commercially available ATV engines, the design of the parking gear mechanism can also be seen. Generally, the parking gear gear on the transmission shaft is clamped by a tenon mechanism (such as a rocker arm or a cam) to achieve the effect of parking brake. The mechanism is also quite complicated; and if the design of the existing engine and related peripherals is to be modified to increase the parking stalls, the problems of difficult space arrangement, excessive design changes, and increased development costs cannot be solved.

Embodiment Construction

[0036] The present invention is a kind of " parking stall mechanism of vehicle ", please refer to figure 1 As shown, the mechanism is located in a crankcase 4, mainly including: a shift lever 1, a shift drum 2, a shift fork 3, a transmission shaft 8, a tooth clutch 7 (dog clutch) , a parking gear gear 6, a block 41, a return spring 5, a shift protection latch 9, a shift protection latch return spring 10.

[0037] The relationship between each component is as follows:

[0038] 1. A transmission shaft 8, please refer to image 3 As shown, there are respectively:

[0039] a. A tooth clutch 7 fixed on the transmission shaft 8 is provided with one or more concave parts 72 and convex parts 71 .

[0040] b. A parking gear 6 that can move axially on the transmission shaft 8, and has one or more convex teeth 61 on it, which can be embedded in the concave portion 72 of the dog clutch 7.

[0041] 2. A block 41, the block 41 is fixed on the crankcase 4 or integrally formed with the cr...

Abstract

The present invention relates to a parking gear mechanism, which comprises a transmission shaft, a parking gear, a block and a tooth clutch. Wherein, the parking gear includes at least one convex tooth, and the parking gear is arranged on the transmission shaft and can move along the axial direction of the transmission shaft. At least one groove is provided on the block, and the groove accommodates the protruding teeth. The dog clutch includes at least one concave portion that can accommodate the convex teeth, and the dog clutch is fixed on the transmission shaft.

Description

technical field [0001] The invention relates to a braking mechanism of a vehicle, in particular to a parking gear braking mechanism of a vehicle. Background technique [0002] In four-wheeled vehicles, the design of the parking gear is roughly classified into two types, one is designed on the gearbox, such as a car gearbox with a parking gear; the other is designed on the frame to fix the drive shaft As a parking stall mechanism. But regardless of the type, generally speaking, the design of the parking gear is placed outside the engine, and most of the engine does not have a parking gear design. Not only the design and assembly process is complicated, but also a lot of space is wasted. [0003] And because of the light and handy characteristics of locomotive engines, many locomotive engines are now widely used in four-wheeled vehicles, such as All Terrain Vehicles (ATVs) such as ATVs. On commercially available ATV engines, the design of the parking gear mechanism can also ...
