Description

Technical Field

[0001] This utility model relates to the field of tractor powertrain installation technology, and in particular to an installation structure for a full-frame ECVT tractor powertrain. Background Technology

[0002] Existing frameless tractors have the following shortcomings:

[0003] 1. The frameless tractor powertrain is installed without a support. The front end is installed together with the front axle and the rear end is installed together with the housing. It does not have enough strength and rigidity, and is prone to breakage. It cannot guarantee the strength and rigidity requirements of the tractor when operating under complex working conditions, thus affecting the tractor's performance and safety.

[0004] 2. The lack of a support for the powertrain of a frameless tractor can cause significant resonance in the cab during complex working conditions, reducing driver comfort and decreasing work efficiency.

[0005] 3. It cannot guarantee reliable power supply from the powertrain, and its adaptability is poor when working in complex conditions such as ultra-deep tillage and deep turning.

[0006] 4. The various loads on existing frameless tractors tend to concentrate on the powertrain body, which has a certain impact on the body and greatly increases the failure rate.

[0007] Therefore, it is necessary to provide a new mounting structure for a full-frame ECVT tractor powertrain to solve the above-mentioned technical problems. Utility Model Content

[0008] The technical problem solved by this utility model is to provide an installation structure for a full-frame ECVT tractor powertrain with high strength and rigidity that can effectively reduce the resonance level in the cab.

[0009] To solve the above-mentioned technical problems, the installation structure of the full-frame ECVT tractor powertrain provided by this utility model includes:

[0010] The right front support, right rear support, left rear support, and left front support are all fixedly installed on the corresponding positions of the powertrain. The right front support, right rear support, left rear support, and left front support are all fixedly connected to the powertrain by a first bolt and a washer. The right front support, right rear support, left rear support, and left front support are all fixedly connected to the vehicle body by a second bolt, a cover plate, a shock absorber, and a nut.

[0011] Preferably, the diameter of the first bolt and the inner diameter of the washer are both 20 mm, and the length of the first bolt is 50 mm.

[0012] Preferably, the diameter of the second bolt is 20mm, the pitch of the second bolt is 1.5, and the length of the second bolt is 140mm.

[0013] Preferably, the shock absorber is an MDS110-65 shock absorber.

[0014] Compared with related technologies, the mounting structure of the full-frame ECVT tractor powertrain provided by this utility model has the following advantages:

[0015] This utility model provides an installation structure for a full-frame ECVT tractor powertrain. It uses four mounting supports and multiple first bolts to fix the powertrain to the chassis, and employs shock absorbers and cover plates, secured to the chassis with second bolts. This provides sufficient strength and rigidity, ensuring the tractor's efficiency and safety under complex working conditions. Simultaneously, the shock absorbers effectively reduce resonance within the cab, improving driver comfort and thus increasing work efficiency. It guarantees reliable power supply, meeting the demands of heavy-load tillage operations such as deep plowing, ultra-deep loosening, and rotary tillage. By integrating the powertrain and chassis into a single unit, it significantly reduces the failure rate, adapts to various complex working conditions, and can withstand the impact of various loads during tractor operation, improving the product's mechanical and performance characteristics.
