Gear shifting mechanism with mistaken reverse gear engaging preventing structure

Abstract

The invention relates to the technical field of automobile components, and discloses a gear shifting mechanism with a mistaken reverse gear engaging preventing structure. The gear shifting mechanism comprises a gear shifting handle, a gear shifting draw wire, a gear shifting base and a gear shifting shaft. A gear shifting head and a gear shifting positioning block are fixed to the gear shifting shaft. The gear shifting shaft is further sleeved with a mistaken engaging preventing elastic piece and a mistaken engaging preventing lock piece which are each in clearance fit with the gear shifting shaft. One end of the mistaken engaging preventing elastic piece is fixedly connected with the gear shifting positioning block, and the other end of the mistaken engaging preventing elastic piece is connected with the mistaken engaging preventing lock piece. The gear shifting base is provided with a mistaken gear engaging preventing plate used for limiting the rotation of the mistaken engaging preventing lock piece in the reverse gear direction. The gear shifting mechanism has the function of effectively preventing the mistaken reverse gear engaging, meanwhile, the structure is simple, and universality is high.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a shifting mechanism with a reverse gear preventing structure. Background technique [0002] During the driving process, the vehicle must adapt to different road conditions by constantly changing gears to ensure that the vehicle is running in a better state. The gears of the vehicle include forward gear, neutral gear and reverse gear, and the switching of these gears is performed by the same shift handle. When the vehicle is moving forward, the neutral gear and the forward gear can be switched freely, but the reverse gear cannot be switched at will, because after switching the reverse gear, the rotation direction of the gearbox output shaft will change. If the vehicle suddenly changes the direction of rotation, it will have a greater impact on the gears and damage the gears and gearboxes. However, since there is only one shift handle, it is easy to mistakenly switch to rever...

Problems solved by technology

When the vehicle is moving forward, the gears of neutral gear and forward gear can be switched freely, but the reverse gear cannot be switched at will, because after switching the reverse gear, the rotation direction of the transmission output shaft will change, which is for the forward gear. If the vehicle suddenly changes the direction of rotation, it will have a greater impact on the gears and damage the gears and gearboxes.

However, since there is only one shift handle, it is easy to mistakenly engage the reverse gear during the shift process, resulting in damage to the gearbox

[0003] Especially for a five-speed gearbox, the gear distribution is as follows: figure 1 As shown, it is usually easy to mistakenly engage the 5th gear and the reverse gear R. Since the 5th gear rotates faster, once the 5th gear is mistakenly engaged to the reverse gear, the impact force will be very large, which will further aggravate the damage of the gear.

[0004] In the prior art, a reverse gear lock is usually added to the shift handle to prevent the reverse gear from being engaged by mistake, but the structure of the shift handle with the reverse gear lock is complicated

Usually, the manufacturing and processing of the gearbox is much more difficult than that of the shift handle, so a gearbox can be used for a variety of vehicles, and the shift handle usually changes with the model, so the structure of the reverse lock also changes and needs to be redesigned , resulting in unnecessary waste
