Embodiment 1

[0036] like figure 1 As shown, a tractor vehicle loading test device for loading test in the forward direction includes a power loading unit 10 , a connection measurement unit, a tractor 3 to be tested and a data acquisition unit 13 .

[0037] Wherein, the power loading unit 10 adopts a loading tractor, which applies load to the entire device according to the change of the forward working condition of the tractor 3 to be tested, so as to meet the loading requirements of the tractor 3 to be tested in changing working conditions.

[0038] The tractor 3 to be tested provides a source of driving force for the entire device, meeting the test requirements for its traction force and the like.

[0039] The connection measurement unit includes a traction force sensor 6 , a first traction rod 1 , a second traction rod 8 , a first connecting piece 2 , and a second connecting piece 11 . The first connector 2 is installed on the rear of the tractor 3 to be tested, and is hinged with one e...

Embodiment 2

[0044] like figure 2As shown, a kind of tractor vehicle load test device for the load test in the backward direction is different from Embodiment 1 in that the first connecting piece 2 is installed on the front of the tractor 3 to be tested, and during the test, the tractor to be tested 3 sets a backward speed, and correspondingly, the loading tractor applies a load to the entire device according to the change of the backward working condition of the tractor 3 to be tested, so as to meet the loading requirements of the tractor 3 to be tested in changing working conditions. Set a forward speed to the loading tractor tractor, and this forward speed is less than the backward speed set by the tractor 3 to be measured (this forward speed is relative to the backward direction of the tractor 3 to be measured, if the second connecting member 11 is installed on the loading tractor At the rear of the vehicle, the forward speed is the speed in the forward direction of the loading tracto...

Abstract

The invention provides a tractor whole vehicle loading test device and test method, and solves the technical problems that an existing tractor performance test device is large in equipment investment, high in development cost and long in construction period, the real working condition of a tractor whole vehicle cannot be reproduced, and certain deviation exists. The tractor loading test device comprises a power loading unit, a connection measurement unit and a data acquisition unit. The connection measurement unit is used for connecting a tractor to be measured with the power loading unit and measuring the traction force of the tractor to be tested; the power loading unit is used for applying a load to the tractor whole vehicle loading test device to meet the loading requirement of the tractor to be tested under variable working conditions; the data acquisition unit is used for acquiring measurement values of the connection measurement unit and performance parameters of the tractor engine and / or the transmission to be tested.

Description

technical field [0001] The invention belongs to the technical field of tractor performance testing, and in particular relates to a tractor vehicle load testing device and a testing method. Background technique [0002] At present, there are not many test methods for tractor vehicle loading in China, and there are few studies. There are more researches on tractor vehicle loading testing abroad, and drum dynamometer testing or powertrain bench testing is generally used. [0003] The drum dynamometer test is to fix the whole tractor on the drum dynamometer, simulate the head-on resistance and heat dissipation of the fan, then drive the tractor, use the drum to load the test tractor tires, and simulate various vehicle weights to achieve The purpose of testing various performances of the tractor. This test method requires large investment in equipment, high development costs, and a long construction period. [0004] The powertrain bench test is to install the tractor powertrain...
