Description

Three-wheel tractor drive axle device

technical field

The utility model relates to a drive axle device of a three-wheel tractor, belonging to the technical field of industry.

Background technique

In recent years, the implementation of the fuel tax has made tractors the most economical and profitable vehicle for road transport, which further catalyzes the upgrading of logistics transport models; the policy guidance of toll-by-weight continues to promote the growth of the tractor market. With the development of the economy, more and more tractors are used in road transportation, and the fields of application are becoming more and more extensive. While the tractor is convenient for transportation, it also saves a lot of manpower. As an important vehicle for road transportation, it has a great advantage in the process of freight transportation, and it is also convenient for people's production and life.

Three-wheel tractors are widely used small industrial vehicles. It pulls multiple trailers to form a train, and often performs cargo transfer at stations, freight yards, docks, warehouses and other places. Since the working environment is often indoors and outdoors, or work on a platform with a large flow of people, it requires environmental protection, safety, a wide range of speed changes, and requires agitation, flexibility, and strong adaptability, making it more widely used.

The use of tractors has four meanings: firstly, the tractors are flexible, so that the vehicles and trains can have better maneuverability when towing vehicles. Secondly, the tractor works reliably, ensuring that the tractor and the trailer are connected reliably, conveniently and quickly, and the production efficiency is improved. Again, the tractor runs smoothly: the traction force can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact load. Finally, tractors are environmentally friendly. The tractors designed today use a large amount of electric energy, which is in line with the concept of environmental protection. During the process, chain loosening or slipping often occurs due to fatigue or wear, seriously affecting normal production or causing accidents.

Utility model content

In order to solve the above problems, the purpose of this utility model is just to solve the above-mentioned deficiencies in the prior art, and the purpose of this utility model is to provide a three-wheel tractor drive axle device.

In order to solve the above problems, the utility model is achieved through the following technical solutions:

The drive axle device of the three-wheel tractor is composed of a mountain wheel transmission system 1, a left half shaft 2, a reduction box 3, a differential 4, an electric motor 5, a right half shaft 6, and a drive axle 7; it is characterized in that: the left The left end of the half shaft 2 is connected with the inner hole of the wheel transmission system 1 through an interference fit; the right end of the left half shaft 2 is connected with the reduction box 3 and the differential 4, and the electric motor 5 is connected with the right end of the reduction box 3; The left end of the right half shaft 6 is connected with the drive axle 7 and has an interference fit; the half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel, and its inner and outer ends each have a universal joint through the flower on the universal joint. The key is connected with the reducer gear and the hub bearing inner ring, and the right half shaft can be adjusted through a set of U-shaped threads. When working, the power is transmitted to the reduction box 3 through the motor 5, and the function of the differential 4 is to increase the input torque and reduce the speed accordingly, and the direction of the torque can be changed according to the needs, and the power is transmitted to the transmission through the half shaft. The wheel drive system 1 realizes the drive of the tractor.

The beneficial effects of the utility model are: the driving axle device of the three-wheel tractor has the advantages of simple structure, safety, stability and reliability, and easy operation.
