Description

Transition gearbox capable of disconnecting gear

Technical Field

The utility model relates to the technical field of transition gear boxes, in particular to a transition gear box capable of disconnecting gears.

Background

Transition gearboxes are components for automotive drive trains, commonly found in some advanced automatic transmissions, which are primarily used to achieve smooth shifts between different gear ratios to provide better power output and driving experience at acceleration and deceleration speeds.

In the using process of the existing four-wheel drive agricultural machine, the following defects exist: the rear drive is inconvenient to disconnect according to the use condition, the fuel quantity and the workpiece load are increased under the condition of continuously keeping the four-drive, the use cost of a user is improved, and therefore, the transition gear box capable of disconnecting gears is provided for solving the problems.

Disclosure of utility model

Aiming at the problems existing in the prior art, the utility model aims to provide a transition gearbox capable of disconnecting gears.

In order to achieve the above purpose, the present utility model adopts the following technical scheme.

The utility model provides a transition gearbox of disconnectable gear, includes the casing, ring flange and the connecting seat rather than the intercommunication are installed respectively to the top and the bottom of casing, the inside of casing is provided with input shaft, jackshaft and output shaft from left to right respectively, the outside cover of input shaft is equipped with rather than sliding connection's slip gear, the outside cover of jackshaft is equipped with the transition gear with the gear engagement that slides, the outside cover of output shaft is equipped with the output gear with transition gear engagement, the inside of casing is provided with the shifting fork of being connected with the gear rotation that slides, the internally mounted of shifting fork has the fork axle.

As a further description of the above technical solution:

The inside of casing is provided with the auto-lock spring, the steel ball is installed to the one end that the auto-lock spring is close to the input shaft, two spacing grooves have been seted up in the outside of fork shaft, the steel ball joint is to the inside in top spacing groove.

Compared with the prior art, the utility model has the advantages that:

According to the scheme, when the agricultural machine is in the cultivation process, if too much resistance exists or larger traction force is needed, the rear drive system can be selectively disconnected, power is mainly transmitted to the front wheels, the rotation resistance and energy loss of the driving part are reduced, so that the fuel consumption is reduced, the service life of the transmission part can be prolonged due to the reduction of the work load of the transmission part, and the maintenance and replacement cost is reduced.

Fig. 1 is a schematic structural view of the present utility model.

The reference numerals in the figures illustrate:

1. A housing; 2. shifting fork; 3. a fork shaft; 4. a self-locking spring; 5. a steel ball; 6. a flange plate; 7. an input shaft; 8. a slipping gear; 9. an intermediate shaft; 10. a transition gear; 11. an output gear; 12. an output shaft; 13. and a connecting seat.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model;

Referring to fig. 1, the utility model relates to a transition gearbox capable of disconnecting gears, which comprises a housing 1, wherein a flange 6 and a connecting seat 13 which are communicated with the top and the bottom of the housing 1 are respectively arranged in the housing 1, an input shaft 7, an intermediate shaft 9 and an output shaft 12 are respectively arranged in the housing 1 from left to right, a sliding gear 8 which is in sliding connection with the input shaft 7 is sleeved outside the input shaft 7, a transition gear 10 which is meshed with the sliding gear 8 is sleeved outside the intermediate shaft 9, an output gear 11 which is meshed with the transition gear 10 is sleeved outside the output shaft 12, a shifting fork 2 which is rotationally connected with the sliding gear 8 is arranged in the housing 1, and a fork shaft 3 is arranged in the shifting fork 2.

In the utility model, the flange 6 and the connecting seat 13 are arranged, so that the shell 1 is convenient to mount and connect, in the normal four-wheel drive process, the input shaft 7, the intermediate shaft 9 and the output shaft 12 can be respectively driven to rotate through the mutual meshing of the sliding gear 8, the transition gear 10 and the output gear 11, thereby completing the four-wheel drive, but when the rear drive is required to be disconnected, the fork shaft 3 can be pulled to drive the shifting fork 2 to move, the sliding gear 8 is separated from the transition gear 10, the rear drive force is not output any more, and meanwhile, when the rear drive is separated in the high-speed transition process of the walking gearbox, the intermediate universal transmission shaft is not idle any more, the overhigh temperature rise is avoided, and the power loss is reduced.

Wherein: the inside of casing 1 is provided with auto-lock spring 4, and steel ball 5 is installed to the one end that auto-lock spring 4 is close to input shaft 7, and two spacing grooves have been seted up in the outside of fork shaft 3, and steel ball 5 joint is to the inside in top spacing groove.

According to the utility model, the self-locking spring 4 is adopted to push the steel ball 5 to be clamped with the limiting groove at the corresponding position on the fork shaft 3, so that the fork shaft 3 is limited and fixed, and the stability of the fork shaft is ensured.

The foregoing is a preferred embodiment of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
