Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] Such as figure 1 The drive device for a harvester includes a variable pump 2 connected to the engine 1 of the harvester. Preferably, the variable pump 2 is a closed hydraulic variable pump, and the variable pump 2 is connected to a quantitative motor 3 and a variable motor 4 respectively. The quantitative motor 3 transmissions are connected to the gearbox 5, the gearbox 5 transmissions are connected to the front axle 6 of the harvester, the rear axle 7 of the harvester is provided with a clutch 8, and the variable motor 4 is connected to the rear axle 7 of the harvester by the clutch 8 trans...

Abstract

The invention discloses a harvester driving device. The harvester driving device comprises a variable pump connected with an engine of a harvester. The variable pump is connected with a constant displacement motor and a variable displacement motor. The constant displacement motor is in drive connection with a gearbox, the gearbox is in drive connection with a front axle of the harvester, a clutch is arranged on a rear axle of the harvester, and the variable displacement motor is in drive connection with the rear axle of the harvester through the clutch. By means of the walking driving device of the hydraulic four-wheel drive harvester, the problem that when the harvester is in a plant transfer working condition, a variable displacement motor rotates at high speed, and power losses are caused is solved, meanwhile, the influence of high-speed rotation of the variable displacement motor on the reliability of the variable displacement motor is avoided, and the reliability of a hydraulic system is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a driving device for a harvester. Background technique [0002] For the current domestic hydraulic four-wheel drive harvesting machinery, the front wheel drive generally uses a fixed motor and box axle, and the rear wheel drive uses a variable motor and box axle. For this scheme, when the harvesting machinery is working in the factory transfer condition, it is necessary to adjust the displacement of the variable motor driven by the rear wheel to 0, so that the rear wheel becomes a free wheel state. The variable motor rotates at a high speed following the driving of the vehicle, and the variable The speed of the motor is about 4000-6000r / min. In this case, the high-speed rotation of the variable motor will cause a large power loss, and at the same time affect the reliability of the variable motor. Contents of the invention [0003] (1) Technical problems to be so...
