[0010] Refer to the attached drawings:

[0011] It includes the front wheel of the tractor (1), the nose (2), the trailer (5), and the rear wheel (6) of the trailer. It consists of a gear pump (3), a hydraulic cylinder (9), a hydraulic tank (4), and a valve-1 (11) On the existing articulated 12Y tractor consisting of hydraulic lifting device and valve-2(8) and the connection device between the front and trailer, an oil motor (7) check valve (10) and valve-3 are added (12) and pipeline (13) composed of hydraulic driving device, in which the oil motor (7) can be modified from 320 or 316, 314, 310 gear pumps, installed on the rear axle of the trailer, two oil motors One end is connected in parallel with a one-way valve (10) through the pipeline, and a manual three-way valve-3(12) is connected in series through the pipeline (13) at one end of the oil motor and one-way valve connected in parallel. -1 (11) and valve -2 (8) are connected in parallel to both ends of the hydraulic oil cyli...

Abstract

The present invention is one hinged tractor with hydraulic driver for back wheels. On the back axle of the hinged tractor, there is one increased hydraulic driver comprising oil motor, non-return valve, valve-3 and pipeline, and the hydraulic driver is used directly in driving the back wheel shaft of the tractor trailer. When the tractor runs in flat road, the increased hydraulic driver does not act, and the tractor is front wheel driven to maintain the superiority of common hinged tractor. During up slope, the hydraulic driver for back wheels is also started to make the tractor become one four-wheel driven one with raised clamping capacity. The tractor of the present invention is suitable for running in various kinds of road, including flat road, mountainous road and road with great slope gradient.

Description

[technical field] [0001] The invention relates to a tractor, in particular to an articulated tractor with a hydraulic driving device on the rear wheel. [Background technique] [0002] At present, the articulated or wheeled tractors produced and sold all over the country, such as ordinary 12Y tractors, are connected by the nose and the trailer through the hinge device in the middle. When walking, they are driven by the front wheels of the nose. The device drags / pushes the trailer box forward / backward. Because the size of the driving force is mainly determined by the friction between the nose and the ground, and the friction is equal to the weight of the nose multiplied by the friction coefficient of the ground. When the friction coefficient is constant, the greater the weight of the nose, the greater the The greater the friction, but the weight of the head of the ordinary tractor remains the same, so the tractor with this structure has poor climbing ability. As long as the c...
