Embodiment Construction

[0020] Embodiment 1 of the torque loading device of the present invention, such as Figure 1-2 As shown: the torque loading device includes a base plate 1, a speed-up box 4, a speed-regulating coupler 7, a torque loader 10, a torque speed sensor and a shaft coupling.

[0021] The speed-up box 4 , the speed-regulating coupler 7 , the torque loader 10 , and the torque speed sensor are arranged on the bottom plate 1 . The torque loader 10 is a loading motor. The speed-regulating coupler 7 is a hydraulic coupler. The speed-regulating coupler 7 has a power input shaft for transmission connection with the tested power device and a power output shaft for connection with the corresponding torque loader 10 . The power input shaft of the speed-regulating coupler 7 is connected to the speed-up box 4, the power input shaft of the speed-regulating coupler 7 is connected to the power device under test through the speed-up box 4, and the power output shaft of the speed-regulating coupler 7...

Abstract

The invention relates to a torque loading device and a tractor testbed with the same. The torque loading device comprises a speed adjusting type coupler which is provided with a power input shaft and a power output shaft. The power input shaft is used for being in transmission connection with a tested power device. The power output shaft is used for being connected with a corresponding torque loader. The shortcoming that according to an existing tractor testbed, a torque loader is directly used for loading is overcome, by changing the speed ratio of the speed adjusting type coupler, a sliding-rotating state according with the reality can be achieved, simulation similarity of a tractor working environment is high, and significance in tractor performance research and improvement is achieved. The torque loading device is suitable for the tractor testbed, and certain universality is achieved on all non-road-surface vehicle whole car experiments, power systems and related part experiments.

Description

technical field [0001] The invention relates to a torque loading device and a tractor test bench using the device. Background technique [0002] With the continuous development of agricultural production, more and more agricultural machinery, especially high-horsepower tractors, are put into production. The industrial goal of agricultural mechanization has higher and higher requirements for tractor performance. [0003] The tractor test bench is a test device used to study and test the performance of tractors. Tractor test benches, including vehicle test benches, power system and other component test benches. Application publication number is that the hybrid power four-wheel-drive tractor test stand announced in the Chinese patent document of CN103175693 is a kind of common tractor test stand, and the loading device that this test stand adopts is a dynamometer, and this dynamometer is directly connected with the tractor during work. There is a large difference between the ...
