Front-drive crawler tractor

Abstract

The invention discloses a front drive crawler tractor which comprises a power source, a gearbox front end is arranged on one side of the power source, a gearbox rear end is arranged on one side of the gearbox front end, steering mechanisms are symmetrically arranged at the bottoms of one sides of the two ends of the gearbox front end, and universal transmission shafts are arranged in the steering mechanisms. Rotating shafts are arranged at the bottoms of one ends of the universal transmission shafts, and driving wheels sleeve the outer sides of the rotating shafts; the gravity center of the whole machine moves forwards after the steering mechanism moves forwards, so that the gravity center is more stable, and the balance weight can be reduced; and as the crawler belt is leveled, compared with an existing rear-drive crawler tractor, under the same grounding length, the needed crawler length is short, the function of an engine is fully played, and the transmission efficiency is improved; meanwhile, the spaces on the two sides of the gearbox are enlarged, arrangement of auxiliary facilities is facilitated, and the space of a cab is enlarged; and the length of the gearbox is shortened, and a longer universal transmission shaft can be used for working output, so that an agricultural implement is lifted to be higher, the trafficability of the tractor is improved, and the gradeability is improved.

Description

Technical field[0001]The present invention relates to the technical field of agricultural equipment, in particular a front drive track tractor.Background technique[0002]The crawler tractor is also called "chain rail tractor" or "track tractor", is a kind of tractor, running, drive wheel winding track cycle movement, rolling on the track of the track or back, crawler and wheel Different tractors, it is supported by a wound annular track, the track contact is inserted into the ground, the transduction is inserted into the soil, the drive is not grounded, the drive wheel is driven under the driving torque, and the wheel tooth on the drive wheel is different. The engagement between the track plate is continuously rolled up from the rear continuously;[0003]The track tractor in the existing market is driven, and there is the following deficiencies: 1. After the tail is mounted, it needs to be equipped with a considerable number of counterweights on the front end of the tail, thereby incre...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of front-drive crawler tractor, to solve the above-mentioned background technology, the crawler tractors in the existing market are all rear-driven, and it has the following disadvantages: 1. In order to adjust the tractor after the tail is mounted The center of gravity needs to be equipped with a considerable amount of counterweight at its front end, thus increasing the weight of the whole machine. Larger space, narrow space in the cab, difficult to arrange auxiliary facilities 3, and the overall length of the gearbox is long, so the length of the cardan shaft of the work output is limited due to the center of gravity, which limits the lifting height of the tractor implements ; 4. Friction is prone to occur at the connection between the cardan transmission shaft and the steering mechanism, and long-term transmission reduces its service life.
