Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. like figure 1 As shown, the tractor transmission device with power reversing and synchronous shifting for small and medium power includes: power reversing transmission device T1, main transmission device T2, auxiliary transmission device T3. The power reversing transmission device T1, the main transmission device T2, and the auxiliary transmission device T3 are arranged in sequence from left to right. The front end of the power reversing transmission device T1 is connected to the engine A0, and the rear end of the auxiliary transmission device T3 is connected to the rear central transmission of the tractor. A2 is connected. Wherein, the power reversing transmission device T1 and the main speed change transmission device T2 are arranged in the front case housing.

[0015] like figure 1 and figure 2 As shown, the drive shaft S1, the reversing output sh...

Abstract

The invention discloses a medium/low-power tractor transmission device with power reversing and synchronous gear shifting. The device comprises a power reversing transmission device, a main speed change transmission device and a secondary speed change transmission device; the power reversing transmission device, the main speed change transmission device and the secondary speed change transmissiondevice are arranged in sequence from left to right; the front end of the power reversing transmission device is connected with an engine; the back end of the secondary speed change transmission deviceis connected with a tractor back center driver; and the power reversing transmission device and the main speed change transmission device are arranged in the same shell. Through the arrangement, thetransmission technical path is clear, the axial size is short, and the structure is compact. Through combination of the power reversing transmission device, the main speed change transmission device and the secondary speed change transmission device in sequence, 16 advancement gears and 16 retreating gears can be realized, so that the gear number is bigger, the speed distribution is reasonable, the applicable working range is wide, and the transmission efficiency is high. The transmission device can realize gear shifting without parking a vehicle, is convenient to shift gears and comfortable in operation.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor transmission device, in particular to a tractor transmission device with power reversing and synchronous gear shifting for medium and small power. Background technique [0002] At present, on various traditional small and medium power tractors in the prior art, the structure of the reversing gearbox is mostly a vertical axis arrangement with 8+8 or 12+12 gears. Because traditional small and medium power tractors are restricted by the space factor of the gearbox housing and the technical level, most of the reversing devices of the existing gearboxes adopt the structural form of sliding gears, meshing sleeves or synchronizers. Due to the difficulty in the initial meshing of the meshing splines or meshing gears, the above-mentioned transmission device will generate a large frictional resistance during the meshing process, and a large shifting force needs to be applied during the shif...
