Transmission method capable of enabling rear wheels of walking tractor to drive

Abstract

The invention discloses a transmission method capable of enabling rear wheels of a walking tractor to drive. A chassis gearbox, a transmission shaft in the gearbox, a trailer drawing frame, fixed bolts, a rear wheel-driven transmission device, a chassis gearbox drawing frame and a transmission shaft, a rear gear box, a rear axle, rear wheels and the like are included, wherein the transmission shaft, the rear gearbox, the rear axle, the rear wheels and the like are assembled on a trailer. The transmission method is characterized in that the trailer drawing frame is additionally arranged on a proper position of a rear wheel-driven walking deformation transport machine or a walking trailer head needing additionally increasing rear wheel drive, the chassis gearbox drawing frame is dismantled, the rear wheel-driven transmission device is directly arranged and fixed on the drawing frame by using fixed bolts so that the rear wheel-driven transmission device can directly take force from the transmission shaft in the gearbox and change the force transfer direction and the rotation motion of the transmission shaft in the gearbox is transmitted to a power output gear shaft; the rear wheels obtain a drive torque from the linkage between one spline and another spline; and the rear gearbox only controls the main speed change of the rear wheels, the front wheels and the rear wheels simultaneously drive, and gears of the front and the rear gearboxes are coordinated to ensure that the front wheels and the rear wheels are synchronized.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a transmission method for driving the rear wheel of a walking tractor. Background technique [0002] Most of the walk-behind transporters (commonly known as square tractors) or walk-behind tractors (commonly known as hand tractors) currently produced in my country are driven by the front wheels. The power output by the diesel engine drives the two front wheels through the clutch, gearbox and steering clutch. The driving wheel has no driving force, and the goods are mainly borne by the rear wheels during short-distance transportation. Due to the small weight of the body such as the front engine and the small adhesion of the front wheels to the ground, it cannot generate large traction, especially in the case of high slopes and steep roads in rural areas, it is easy to slip and cannot walk, so it can only be used very deeply. The treaded tires and the thr...

Problems solved by technology

[0005] The content of the present invention is to aim at the defects of the hand trailer produced by applying the patented technology of "a transmission device that can drive the rear wheel of a walking tractor", such as: it is inconvenient to attach or unmount the trailer, and the hand trailer is inconvenient when driving. Or when bending over and turning, the compressive stress generated between the transmission components cannot be eliminated, so that the vehicle is easy to be damaged prematurely. The transmission method of the rear wheel drive is further optimized to solve the various shortcomings of the patented product. Better performance and more perfect functions
