Problems solved by technology

At present, domestic tractors generally use traditional gearboxes with reverse gears. The number of reverse gears is generally 2 to 4, and the minimum speed is greater than 1.5km / h. Due to the small number of gears and narrow speed range, it is difficult to adapt to fast and efficient operations. Require
In addition, when the tractor shifts gears, the impact force and the required operating force are relatively large, which often brings discomfort to the driver.
Therefore, tractors equipped with traditional gearboxes cannot meet user needs

Embodiment Construction

[0013] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the synchronous reversing tractor gearbox with crawler gear consists of four parts: synchronizer reversing device T1, main transmission device T2, auxiliary transmission device T3 and crawler gear device T4. Among them, one end of synchronous reversing device T1 is connected with engine A, crawler gear device T4 is connected with small bevel gear shaft S5, here the power is transmitted in two ways, one way leads to tractor rear axle D through small bevel gear shaft S5, and the other way passes through small bevel gear shaft S5 The four-wheel drive driving gear 18 installed on the bevel gear shaft leads to the front axle C of the tractor.

[0014] The main clutch shaft S1, the reversing driven gear shaft S9, and the reversing idler shaft S8 are installed in the synchronous reversing device T1; the main transmission drive shaft S3...

Abstract

The invention discloses a synchronous reversing belt crawling-gear gearbox of a tractor. The synchronous reversing belt crawling-gear gearbox comprises a synchronizer reversing device, a main speed variator, an auxiliary speed variator and a crawling gear device which are sequentially arranged. One end of the synchronizer reversing device is connected with an engine, and one end of the crawling gear device is connected with a bevel pinion. The synchronizer reversing device and the main speed variator are double-friction-cone synchronizers. By combining the synchronizer reversing device, the main speed variator, the auxiliary speed variator and the crawling gear device, 32 forward gears and 32 reverse gears can be realized, the more the reverse gears are, the better the operation needs can be met. The synchronizer reversing device is disposed at the front end of the main speed variator, gear reversing and engaging of the double-friction-cone synchronizers are realized, parking for gear engagement is omitted when at low speed, gear shift impact and force are low, gear shift time is short, and operation efficiency is high.

Description

[0001] technical field [0002] The invention belongs to the field of tractors, and relates to a tractor gearbox, in particular to a tractor gearbox with synchronous reversing and crawling gear. Background technique [0003] With the rapid improvement of the level of agricultural mechanization in my country, users' requirements for tractors are no longer limited to traditional operations such as plowing and harrowing, but also hope to complete auxiliary production tasks in agricultural production, such as reciprocating production materials within a short distance. At the same time, there are further requirements for the ultra-low speed of the tractor below 0.3km / h and the handling comfort. At present, domestic tractors generally use traditional gearboxes with reverse gears. The number of reverse gears is generally 2 to 4, and the minimum speed is greater than 1.5km / h. Due to the small number of gears and narrow speed range, it is difficult to adapt to fast and efficient oper...
