Abstract

The invention provides a gearbox with a crawling block and a retrograde device for a tractor. The gearbox with the crawling block and the retrograde device for the tractor comprises a retrograde device, a crawling block device, a main speed change device and an auxiliary speed change device; the retrograde device, the crawling block device, the main speed change device and the auxiliary speed change device are arranged in sequence, one end of the retrograde device is connected with a motor, and one end of the auxiliary speed change device is connected with a rear axle of the tractor; the retrograde device and the crawling block are arranged in a front transmission box, and the main speed change device and the auxiliary speed change device are arranged in a rear transmission box. According to the gearbox with the crawling block and the retrograde device for the tractor, a synchronizer structure is adopted to achieve convenient reverse gear, gear shifting impinge and gear shifting force are small, gear shifting time is less, and work efficiency is high; the crawling block can obtain a larger reduction ratio due to speed reducing realized through a three-stage gear, and the maximum speed of the crawling block can be lower; a synchronizer is adopted in the main speed change device to shift gear, the gear shifting can be conducted without stopping the tractor, gear shifting impinge and gear shifting force are small, and work efficiency is high; an auxiliary speed change driven shaft in the auxiliary speed change device is integrated with a small bevel gear, and the structure is compact and nimble.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a transmission box with a crawler gear and a reverser for the tractor. Background technique [0002] At present, on various large and medium power tractors produced at home and abroad, the crawler gears selected are generally arranged at the rear of the tractor drive train. Due to its structural limitations, gearboxes equipped with creeping gears generally cannot be equipped with a reverser. Although some tractors have the functions of crawler gear and reverse gear at the same time, the reverse gear is generally arranged in the front transmission box, and the crawler gear is arranged in the rear transmission box. This makes the structure of the whole machine more complex, and the degree of modularization and generalization of the drive train is low. In view of the current technical situation of tractor products in our country, it is urgent to develop a tractor gearbox that has the functio...
