Three-speed gear transmission gearbox with gear striking preventing function

Abstract

The invention belongs to the technical field of gear transmission gearboxes, and particularly relates to a three-speed gear transmission gearbox with a gear striking preventing function. The three-speed gear transmission gearbox with the gear striking preventing function comprises an output shaft, a clamping mechanism, a first fixing ring, a shifting rod, a first fixing plate, a supporting mechanism, a first guide block, a second guide block, a third guide block, a fixing housing, an input shaft, a first connecting barrel, a second fixing ring, a fixing block, a third fixing ring, etc., wherein a storing chamber is formed in the fixing housing; a through fixing circular hole is formed in the side surface of the storing chamber; a through moving groove is formed in the side surface, opposite to the fixing circular hole, of the storing chamber; two first guide grooves are symmetrically formed in the outer circle surface of the input shaft; and two third guide grooves are symmetrically formed in the outer circle surface of the input shaft. According to the gear transmission gearbox, when a gear which rotates at a slow speed is forcibly embedded into a gear which rotates at a high speed, or when the gear which rotates at the high speed is forcibly embedded into the gear which rotates at a slow speed, the problem of gear striking in the gearbox can be avoided.

Description

technical field [0001] The invention belongs to the technical field of gear transmission gearboxes, and in particular relates to a three-speed gear transmission gearbox with the function of preventing tooth hitting. Background technique [0002] At present, the existing gear transmission gearboxes often cause damage to the gearbox gears due to the user's misoperation. As far as automobile gearboxes are concerned, it is generally required to step on the clutch to the bottom during manual shifting, and then perform gear shifting operations. When the speed is basically the same, loosen the clutch and complete the gear shift. When the engine speed does not match the wheel speed, not only will there be gear noises when the user shifts gears, but it will also easily cause gear hitting. If the gear is forcibly inserted into a high-speed rotating gear, the phenomenon of tooth hitting will definitely occur. In order to avoid this kind of situation, it is very necessary to design a th...

[0002] At present, the existing gear transmission gearboxes often cause damage to the gearbox gears due to the user's misoperation. As far as automobile gearboxes are concerned, it is generally required to step on the clutch to the bottom during manual shifting, and then perform gear shifting operations. When the speed is basically the same, loosen the clutch and complete the gear shift. When the engine speed does not match the wheel speed, not only will there be gear noises when the user shifts gears, but it will also easily cause gear hitting. If the gear is forcibly inserted into a high-speed rotating gear, the phenomenon of tooth beating will definitely occur. In order to avoid this kind of situation, it is very necessary to design a three-speed gear transmission gearbox with the function of preventing tooth beating.
