Problems solved by technology

[0002] At present, domestic tractors are all two-wheel drive or four-wheel drive. Two-wheel drive tractors have no driving force constraints on the front wheels, and the steering is relatively flexible, but they are not suitable for working conditions that require large traction; four-wheel drive tractors have large traction and strong climbing ability. , the engine braking effect is good, but because the front-wheel drive is mandatory, the speed of the front wheels will not increase with the increase of the corner, but will produce resistance, which will increase the turning radius, increase the turning time, and turn traces of damage to land, etc.

Embodiment 1

[0038] like figure 1As shown, a tractor front wheel speed-increasing steering device in this embodiment includes a rear axle housing 1, an input shaft 2, an idler shaft 3 and a transfer case output shaft 4. The input shaft 2, the idler shaft 3 and the splitter The transmission case output shafts 4 are parallel to each other and are respectively rotatably connected in the rear axle housing 1; The double-speed idler 31 and the double-speed idler 32, the transfer case output shaft 4 is respectively movably connected with a non-double-speed driven gear 41 and a double-speed driven gear 42, and the transfer case driving gear 21 meshes with the non-double-speed idler 31, The non-double-speed idler 31 meshes with the non-double-speed driven gear 41, and the double-speed idler 32 meshes with the double-speed driven gear 42; the transfer case output shaft 4 is provided with a first clutch 5 and a second clutch 6, so The first clutch 5 is matched with the non-double-speed driven gear 4...

Embodiment 2

[0052] like figure 1 and figure 2 As shown, a tractor front wheel speed increasing steering system in this embodiment includes the tractor front wheel speed increasing steering device, and further includes: a front axle angle sensor, a rotational speed sensor and a controller, the front axle angle sensor is installed on the front axle and used to send the detected steering angle of the front axle to the controller, the speed sensor is mounted on the tractor chassis and used to send the detected speed of the tractor to the controller;

[0053] The controller is used for the steering angle of the front axle not less than the preset angle, and when the speed of the tractor is not greater than the preset speed, to control the second clutch to contact the double-speed driven gear, so that the transfer case output shaft 4 enters the double-speed mode;

[0054] The controller is used for the steering angle of the front axle not less than the preset angle, and when the speed of the ...

Abstract

The invention relates to a tractor front wheel speedup steering device and a steering system, the steering device comprises a rear axle housing, an input shaft, an idler shaft and a transfer case output shaft, and the input shaft, the idler shaft and the transfer case output shaft are parallel to one another and are respectively rotatably connected in the rear axle housing; a transfer case driving gear is connected to the input shaft through a spline, a non-multiplied-speed idle gear and a multiplied-speed idle gear are connected to the idle gear shaft through splines, a non-multiplied-speed driven gear and a multiplied-speed driven gear are movably connected to the transfer case output shaft, the transfer case driving gear is meshed with the non-multiplied-speed idle gear, the non-multiplied-speed idle gear is meshed with the non-multiplied-speed driven gear, and the multiplied-speed idle gear is meshed with the multiplied-speed driven gear. The multi-speed idle gear is meshed with the multi-speed driven gear; a first clutch and a second clutch are arranged on the transfer case output shaft, the first clutch is correspondingly matched with the non-multiplied-speed driven gear and drives the transfer case output shaft to enter a four-wheel drive mode or a two-wheel drive mode, and the second clutch is correspondingly matched with the multiplied-speed driven gear and drives the transfer case output shaft to enter a multiplied-speed mode or a two-wheel drive mode.

Description

technical field [0001] The invention relates to the related technical field of tractors, in particular to a front wheel speed-increasing steering device and a steering system of a tractor. Background technique [0002] At present, domestic tractors are all two-wheel drive or four-wheel drive. The front wheels of two-wheel drive tractors have no driving force constraints, and the steering is relatively flexible, but they are not suitable for working conditions that require large traction; four-wheel drive tractors have large traction and strong climbing ability. , The engine braking effect is good, but because the front wheel drive is mandatory, the front wheel speed will not increase with the increase of the turning angle, but will generate resistance, which will cause the turning radius to increase, the turning time to increase, and the turning Traces of damage to the land, etc. SUMMARY OF THE INVENTION [0003] In order to solve one or more of the above technical proble...
