Embodiment

[0024] Example: see Figure 1 to Figure 5 , a tractor double-speed steering mechanism, including a left front wheel 1, a right front wheel 2, a front axle assembly, a steering wheel assembly 4, a double-speed gearbox, and a double-speed joystick 6. The left front wheel 1 and the right front wheel 2 are respectively connected to the two ends of the front axle assembly. The steering wheel assembly 4 is connected with the left front wheel 1 through the front axle steering connecting rod 7, and the left front wheel 1 is connected with the right front wheel 2 through the steering connecting rod 8, so that the steering wheel assembly 4 can drive the left front wheel 1 and the right front wheel Wheel 2 rotates synchronously. The double-speed gearbox includes a box body 51, a case cover 52, a power input shaft 53, a spline connection sleeve 54, a power input gear 55, a double-speed input driving gear 56, a double-speed input driven gear 57, a double-speed transmission shaft 58, and a...

Abstract

The invention discloses a tractor multi-speed steering mechanism. The multi-speed steering mechanism comprises a left front wheel, a right front wheel, a front axle assembly, a steering wheel assembly, a multi-speed gearbox and a multi-speed manipulating handle; the multi-speed gearbox is connected with a front axle input shaft of the front axle assembly; a multi-speed gear shifting fork is arranged at the portion, corresponding to a multi-speed gear shifting cam, of a box body; the right end of a rotary shaft extends out of the right side of the box body, and is connected with a driving wrenching plate; a multi-speed driving connecting plate is arranged at the end, close to the right front wheel, of a front axle shell of the front axle assembly, and a front axle multi-speed connecting plate is arranged at the right front wheel; a multi-speed connecting rod is arranged between the front axle multi-speed connecting plate and the multi-speed driving connecting plate, a multi-speed ball head top rod is arranged between the multi-speed driving connecting plate and the driving wrenching plate, and a tension spring is arranged between the multi-speed driving connecting plate and the upper end of the driving wrenching plate. According to the tractor multi-speed steering mechanism, the turning radius of a tractor can be effectively reduced, the cultivation efficiency of the tractor is improved, and the fuel consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to a multi-speed steering mechanism of a tractor. Background technique [0002] At present, in the process of agricultural production, tractors are widely used for plowing, sowing, etc.; when the tractor runs to one end of the work area, it needs to turn (turn around), and work again after turning (turn around). However, due to the structural limitations of existing tractors and the relatively slow rotational speed of the front wheels when the tractor turns, the tractor can only move forward with a large radius trajectory when turning, and the front wheels cannot use the rear wheels as fulcrums for fast compass steering; As a result, when the tractor turns to the second road after plowing the first road, due to the large turning radius, the edge of the second road cannot coincide with the edge of the first road, and there is a large plowing gap, resulting in tractor farming efficie...
