A new type of driving steering gearbox

Abstract

A new type of driving steering gearbox is composed of an upper box body (27), an upper box bevel gear shaft (8), an upper box bevel gear (28), a main shaft (4), a lower box body (13), a lower box bevel gear shaft (23), a lower box bevel gear (14) and related bearings, oil seals, retaining rings, end covers, screws and nuts, gaskets and other parts. The driving steering gearbox is composed of an upper box body and a lower box body, and any one of the boxes can be used as power input and the other box body can be used as power output. When installing, the power input box body is fixed so that the power output box body can rotate freely 360 degrees around the power input box body during operation, thereby meeting the needs of farmers who use various wheeled tractors and micro-tillage machines with trailers to drive large-angle sharp turns in places with steep slopes, narrow roads and sharp bends. It can also be widely used in other machines whose power output end needs to change the output direction arbitrarily.

Description

Technical Field

[0001] The present invention is a driving steering device, in particular to a brand-new driving steering gear box device. Background Art

[0002] At present, the walk-behind tractors and micro-tillage machines produced and sold in my country are very suitable for hilly and mountainous areas due to their low cost, light weight, and wide range of functions. They are very popular among farmers and their social ownership is rapidly expanding. Many farmers take walk-behind tractors and micro-tillage machines on trailers for field transportation according to their own production needs. However, due to the waist-bending steering between the head of the walk-behind tractor and micro-tillage machine and the trailer, universal joints are widely used for steering and driving. Since the turning angle of the universal joint is small, the maximum turning angle cannot exceed 38 degrees, and most of the mountainous areas are steep, narrow, and bendy, the turning of the universal joint is far from meeting the requirements of use, and there are certain safety hazards. There is an urgent need for a device with a large turning angle to replace the existing universal joint. According to the urgent requirements of many farmers, I have successfully developed a driving steering gearbox device through repeated experiments and continuous innovation. Summary of the invention

[0003] In order to enable a walk-behind tractor and a micro-tillage machine with a trailer to normally engage in field transportation, the present invention provides a new driving and steering gear box device.

[0004] In order to solve the technical problems, the technical scheme adopted by the present invention is as follows: ① The driving steering gearbox is composed of an upper box body, an upper box bevel gear shaft, an upper box bevel gear, a main shaft, an upper end cover, an upper box main bearing, an upper box bevel gear shaft bearing, an upper box bevel gear shaft oil seal, an upper box body support bearing, an upper and lower box sealing oil seal, a lower box body, a lower box bevel gear shaft, a lower box bevel gear, a lower end cover, a lower box main bearing, a lower box bevel gear shaft bearing, a lower box bevel gear shaft oil seal, a fixing plate and related screws, gaskets, retaining springs and other parts. ② The driving steering gearbox is composed of an upper box body and a lower box body, an upper box bevel gear shaft and an upper box bevel gear are installed in the upper box body, a lower box bevel gear shaft and a lower box bevel gear are installed in the lower box body, and the upper box bevel gear and the lower box bevel gear are installed at both ends of the same main shaft. ③ During operation, any one of the upper box body and the lower box body can be used as input and the other box body can be used as output as needed. ④Fix the input box during installation to ensure that the input box does not loosen or rotate during operation, and that the output box can rotate freely 360 degrees around the input box during operation.

[0005] The beneficial effects of the present invention are as follows: ① Since the power output housing of the driving steering gearbox can freely rotate 360 ​​degrees around the power input housing during operation, it meets the needs of farmers in mountainous areas to use walking tractors and micro-tillage machines and other transport machinery that need to bend and turn at a large angle in places with steep slopes, narrow roads and sharp bends, greatly improving the safety performance. ② A series of products are manufactured using the structure and principle of the driving steering gearbox, which can be widely used in micro-tillage machines, walking tractors, wheeled tractors and other machinery with trailer drives that need to bend and turn, and can also be widely used in other machinery where the power output end needs to change the output direction arbitrarily.

DETAILED DESCRIPTION

[0009] Referring to the accompanying drawings, an upper box bevel gear shaft (8), an upper box bevel gear (28) and an upper portion of a main shaft (4) are installed in an upper box body (27); the upper box bevel gear shaft (8) is fixed to a side hole of the upper box body (27) through two upper box bevel gear shaft bearings (6) and an upper box bevel gear shaft bearing shaft clamp (7), an upper box bevel gear shaft bearing hole clamp (10) and an upper box bevel gear shaft oil seal (9); the upper box bevel gear (28) is installed on the upper portion of the main shaft (4), the tail end of the upper box bevel gear (28) is fixed to the main shaft (4) through an upper box main bearing (29), and the upper portion of the main shaft (4) is fixed to the main hole of the upper box body (27) through an upper box body support bearing (12), an upper box main bearing (29), a main shaft upper end fastening nut gasket (5), a main shaft upper end fastening nut (3), an upper end cover (2) and an upper end cover fastening screw (1). By adjusting the adjusting pad (26), a normal meshing clearance is maintained between the upper box bevel gear shaft (8) and the upper box bevel gear (28). A lower box bevel gear shaft (23), a lower box bevel gear (14) and the lower part of the main shaft (4) are installed in the lower box body (13); the lower box bevel gear shaft (23) is fixed to the side hole of the lower box body (13) through two lower box bevel gear shaft bearings (21), a lower box bevel gear shaft bearing shaft clamp (24), a lower box bevel gear shaft bearing hole clamp (25) and a lower box bevel gear shaft oil seal (22); the lower box bevel gear (14) is installed on the lower part of the main shaft (4), and the tail end of the lower box bevel gear (14) is fixed to the main shaft (4) through the lower box main bearing (17); the lower part of the main shaft (4) is fixed in the main hole of the lower box body (13) through the lower box main bearing (17), a main shaft lower end fastening nut gasket (20), a main shaft lower end fastening nut (18), a lower end cover (19), and a lower end cover and a fixing plate connecting screw (16). An upper and lower box sealing oil seal (11) is installed at the joint of the upper box (27) and the lower box (13) to ensure that the lubricating oil in the upper box (27) and the lower box (13) does not leak. One end of the fixing plate (15) is connected to the box at the power input end to ensure that the lower box (13) does not loosen or rotate during operation, so that the upper box (27) can rotate freely 360 degrees around the lower box (13) during operation.

[0010] The working process of the driving steering gearbox is: a. Driving process. The lower box bevel gear shaft (23) rotates under the drive of external force, and drives the lower box bevel gear (14) to rotate at the same time, the lower box bevel gear (14) drives the main shaft (4) to rotate at the same time, the main shaft (4) drives the upper box bevel gear (28) to rotate at the same time, and the upper box bevel gear (28) drives the upper box bevel gear shaft (8) to rotate at the same time to transmit power. B. Steering process. The upper box bevel gear shaft (8) is swung as needed to drive the upper box body (27) to rotate around the lower box body (13). Since the lower box body (13) is fixed, simultaneous driving and steering are achieved.
