Abstract

The utility model relates to a transmission case of transverse axis driving tractor, in particular to a tractor transmission case with synchronous laterally-arranged power output shaft. At present, all the tractors with transverse axis driving transmission case sold in market are not provided with synchronous laterally-arranged power output shaft. But in cropland operation, tractors and farm implements such as seedling machines and fertilizer applicators all need synchronous laterally-arranged power output shaft to provide power to front wheel driving shaft in four-wheel drive tractor variant, reducing due mechanical effect and application range of tractors. Based on prior transmission case of transverse axis driving tractor, the utility model adds one-shaft-two-part synchronous laterally-arranged power output shaft, which preferably solves the above existing malady, and improves tractor mechanical effect and application range.

Description

Band synchronous mode side pto gear box of tractor

Technical field

The utility model relates to the gearbox of transverse axis transmission tractor, particularly is with synchronous mode side pto gear box of tractor.

Background technique

The gearbox of present transverse axis transmission tractor, have advantages such as simple in structure, technology maturation, cost be low, be widely used in tractor with small four wheels production, because farm implements such as the sowing machine that tractor uses at farmland operation, fertilizer applicator, or when carrying out the four-wheel drive tractor modification (providing power) to front wheel driving shaft, all need tractor that synchronous mode side pto should be arranged, and the tractor of existing transverse axis transfer gear box, all do not have synchronous mode side pto, therefore, tractor using effect and application area have been reduced.

Technological scheme

The purpose of this utility model is: provide to have synchronous mode side pto gear box of tractor, on existing transverse axis transmission gear box of tractor basis, in gearbox, increase the synchronous mode side pto at one two place, better satisfy agricultural machinery and implement such as tractor configuration sowing machine, fertilizer applicator or carried out compages needs such as four-wheel drive tractor modification, thereby improved tractor advanced person and practicability.

The technical solution of the utility model is: on the basis of existing transverse axis transmission gear box of tractor, below gearbox V axial region position, increase a synchronous mode side pto that has one two place of driven gear, its synchronous dynamic, utilize driven gear to be meshed to realize with deceleration gearwheel on the V axial region position, have simple in structure, implement actively effect such as easy, practical.

Description of drawings

Fig. 1 is the utility model structure cross-sectional schematic; Fig. 2 is that the A-A among Fig. 1 analyses and observe the deployed configuration schematic representation.

The contrast accompanying drawing is described further the utility model embodiment:

Corresponding gear on I, II among the figure, III, IV, V, VI axle, differential mechanism and each and the differential mechanism, form gearbox Pyatyi main transmission structure, the power of diesel engine is realized final two VI axles (or claiming a left side and right live axle) work running through the main transmission of gearbox Pyatyi, its Pyatyi main transmission route is the prior art structure, is not described in detail in this.

The driven gear 3 that side pto VII and last key thereof connect, belong to the structure that the utility model increases newly, the place, two ends of side pto VII is processed with spline axle head, its synchronous dynamic drive path, through the I-VI axle and corresponding on driving gear → IV axle on small gear 4 → deceleration gearwheel 2 → driven gear 3, realize the running of side pto synchronous working, the I axle is to the synchronous working operation route of the gearwheel 2 that slows down, be prior art, at this, describe in detail no longer separately, the utility model technology inheritance is good, generalization degree height, being beneficial to convenient tissue produces.

Claims

1. be with synchronous mode side pto gear box of tractor, it comprise the I-VII axle of arranging in gearbox casing (1), the gearbox casing (1) and differential mechanism (5), and corresponding with it on driving gear, it is characterized in that: the driven gear (3) of key connecting is housed on the synchronous mode side pto VII, and driven gear (3) is meshed with deceleration gearwheel (2) on the V axial region position.
