Direct connection transmission gearbox assembly for caterpillar tractor and caterpillar tractor with same

Abstract

The invention relates to a direct connection transmission gearbox assembly for a caterpillar tractor, and belongs to the field of agricultural tractors. In the power transmission sequence, the direct connection transmission gearbox assembly sequentially comprises an engine, a universal joint, a direct connection gearbox, a coupling and a rear gearbox. The engine provides power, power output power is transmitted to the direct connection gearbox through the universal joint, the direct connection gearbox transmits the power to the coupling through gear engagement, the coupling transmits the power to the rear gearbox through bolted connection, and thus direct connection transmission of the power is achieved. According to the direct connection transmission gearbox assembly, the chassis structure of a caterpillar harvester is used for reference and is applied to the agricultural tractor, and the problem that tractors can not be used for cultivation in part of paddy fields or dry fields in southern hilly regions is solved; the unique direct connection transmission mechanism is adopted, the output power of the engine is transmitted to a rotary cultivator, a ridger, a ditcher and other working components in a direct connection mode, and thus the utilization rate of generator power is increased.

Description

technical field [0001] The invention relates to the field of agricultural tractors, in particular to a crawler tractor direct-coupled transmission gearbox assembly and the crawler tractor. Background technique [0002] At present, some paddy and dry fields in the southern hilly areas use wheeled tractors, and some still use artificial animal power. Due to the damage of the high-toothed wheel of the wheeled tractor to the stratum of the cultivated plow, some soft soil fields have been plowed deeper and deeper, and finally they cannot be plowed by machines; The gap between the ridges makes it impossible to cultivate with wheeled tractors. Therefore, tractors adapted to paddy and dry fields in the southern hills have strong practicability and good market prospects.

Problems solved by technology

[0003] The patent application 201210103199.1 of the present invention published by the State Intellectual Property Office of China on August 22, 2012 discloses a crawler-type combined tillage machine. In this technical solution, a belt is used to transmit power between the engine and the gearbox, and the power utilization rate is low and safe. The coefficient is low, and the belt must be tensioned frequently

[0004] The patent application 201410087756.4 of the present invention published by the State Intellectual Property Office of China on June 11, 2014 discloses a direct-drive horizontal shaft gearbox assembly, which replaces the belt drive with direct drive, but this horizontal shaft gearbox The assembly is mainly suitable for wheeled tractors, not for crawler tractors
