Abstract

The invention relates to a trailer driving device, and particularly relates to a trailer driving device for a four-wheel drive tractor. The towing driving device for the four-wheel drive tractor aims at solving the problem that a farm trailer influences agricultural production and transportation by being sunk into a mud pit or silt due to insufficient traction power of the four-wheel drive tractor when operating in a farmland with poor road conditions. The other end of a trailer driving shaft is connected with a first three-tooth connecting gear through a universal joint; one end of a transmission case connecting shaft is inserted into the first three-tooth connecting gear, and the other end of the transmission case connecting shaft is connected with a transmission case; the first three-tooth connecting gear is sleeved on the transmission case connecting shaft; the transmission case is connected with one end of an intermediate transmission shaft assembly through the universal joint; the other end of the intermediate transmission shaft assembly is connected with an on-off transmission mechanism through the universal joint; and the on-off transmission mechanism is connected with one end of a power shaft through the universal joint. The trailer driving device disclosed by the invention is used for agricultural transportation vehicles.

Description

technical field [0001] The invention relates to a trailer driving device, in particular to a trailer driving device for a four-wheel drive tractor. Background technique [0002] Four-wheel drive tractors are commonly used traction tools in agricultural production. They are usually used to tow agricultural trailers. Existing agricultural trailers are generally not equipped with their own power systems. It often causes the agricultural trailer to fall into the mud pit or silt, such as rainy and snowy days, on the muddy road uphill, the load is not enough, and the power of the main vehicle is surplus. Due to the insufficient traction power of the four-wheel drive tractor, the agricultural trailer often falls into the mud pit or silt, thus affecting agriculture. Production and Shipping. SUMMARY OF THE INVENTION [0003] In order to solve the problem that agricultural trailers often fall into mud pits or silt due to insufficient traction power of the four-wheel drive tractor d...
