Problems solved by technology

[0002] At present, agricultural mechanization is an important measure to solve the three rural issues and realize agricultural modernization. A considerable part of agricultural machinery is agricultural tractors, which are used for short-distance transportation and are one of the main means of transportation in rural areas. Low efficiency, low work efficiency, high cost, high fuel consumption, poor reliability, and very poor economical use. The main reasons are: 1. The front axle is integrated with the transmission, and the structure is complex, and the transmission efficiency is reduced. 2. The front axle Without brakes, the braking effect is not good, the safety is poor, and the controllability is poor. Third, two transmissions are required to realize the synchronization of a certain gear, which increases the cost of a transmission and increases the cost. At the same time, the climbing ability is not strong. The load capacity is not large, and the driving stability is not good on bad roads
4. The transmission system is complicated, the fuel consumption is large, and the use economy is poor
5. Poor overall performance
Existing tractors use a welded rigid connection between the front axle and the frame, which makes the tractor prone to shocks when driving on uneven roads, causing the vehicle to fail to absorb vibration, and affecting the driver's driving comfort and vehicle safety. For the stability of climbing, the tractors of the existing tractors are not optimal within the national standard. Too large a tractor makes the relative angle between the tractor and the carriage chassis large, which makes the turning radius of the tractor larger, which is not good. Facilitates flexible turning when the vehicle is driving on narrow roads

Abstract

A tractor relates to the technical field of agricultural machineries. A belt pulley of the tractor is integrated with a transmission case, the transmission case is connected with an auxiliary gear box and transmits power to the same, a speed gear selecting rod is arranged on the auxiliary gear box which is connected with a gear box, a gear shifting shaft and a gear selecting shaft are arranged on the gear box, the gear box is connected with a transfer case, a transfer selecting rod is arranged on the transfer case, one side of the transfer case is connected with a front transmission shaft connected with a front bridge, the other side of the transfer case is connected with a middle transmission shaft connected with a rear driving combination case, a rear driving operation rod is arranged on the rear driving combination case connected with a rear transmission shaft, and the rear transmission shaft is connected with a rear bridge. The tractor is simple in structure, good in reliability, high in transmission effect, stable in transmission, wide in application range, long in service life, low in cost, large in heavy load due to utilization of the above transmission system , high in working efficiency and economical utilization efficiency, flexible in turning during travelling, and convenient to utilize.

Description

Technical field: [0001] The invention relates to the technical field of agricultural machinery, in particular to a transmission system of a time-sharing four-wheel drive tractor and a tractor front frame with vibration reduction and sensitive steering.
