Embodiment 1

[0039] see Figure 1-5As shown, the present invention provides a four-wheel drive test device, which includes a main body. The main body includes two sets of testing platforms 1 arranged horizontally and in parallel. The same ends of the two sets of testing platforms 1 are provided with a fixed frame 2, and a tension force is provided on the fixed frame 2. Sensor; the detection platform 1 is provided with a road surface simulation device and four detachable skid devices 101, the road surface simulation device includes several base plates 102 and four detachable movable plates 103, and three groups of lateral adjustments are arranged between two groups of detection platforms 1 Device 104; fixed frame 2 comprises the first horizontal bar 201 that is fixed between two groups of detection platforms 1, and the first horizontal bar 201 is provided with two vertically arranged base risers 202, the lower end of base riser 202 Sleeved on the first horizontal bar 201, the base vertical ...

Embodiment 2

[0043] see Image 6 As shown, the difference between Embodiment 2 and Embodiment 1 is that four sets of support devices 3 are provided on both sides of the body, and the support devices 3 are used to lift the tires of the vehicle to be detected from the detection platform 1 for The positions of the movable plate 103 and the skid device 101 are adjusted, which saves the trouble of driving the car down to adjust the movable plate 103 and the skid device 101 and then driving the car to detect once.

Embodiment 3

[0045] see Figure 7 As shown, the difference between Embodiment 3 and Embodiment 1 is that the detection device also includes a data acquisition device 5, and the data acquisition device 5 is connected to the tension sensor through the data transmission system 4 for collecting specific data and performing subsequent analysis , Inspectors can completely collect vehicle data that is being inspected outdoors indoors without being affected by outdoor weather and other reasons. The data transmission system 4 is a wireless APN network, which does not need to set up a special data transmission line, which saves detection costs.

[0046] Described four-wheel drive test method comprises the following steps:

[0047] Step 1. Place the detection platform on a level ground and fix it;

[0048] Step 2. According to the model of the vehicle to be detected, adjust the distance between the two groups of detection platforms through the detection lateral adjustment device;

[0049] Step 3. ...

Abstract

The invention discloses a four-wheel-driving test device and a test method thereof. The device comprises a body. The body comprises two groups of horizontal detection platforms which are arranged in parallel. Same ends of the two groups of detection platforms are provided with fixing racks. The detection platforms are provided with pavement simulation devices and several detachable skid apparatuses. Each pavement simulation device comprises several substrates and several detachable movable plates. Several transverse adjusting devices are arranged between the two groups of detection platforms. Through changing a position of a pulley group, different quantities of tyres to be measured are arranged on an antiskid plate, and the residual tyres are arranged above the pulley group. A tow hook of a rear portion of a vehicle is connected to a tension sensor of each fixing rack through a traction band. When a gas of the vehicle to be measured is gradually increased, a corresponding traction force curve is displayed on a computer so that a power transmission distribution ratio among shafts and wheels of a four-wheel-driving system of the vehicle to be measured and power distribution of a traction force control system can be objectively analyzed, and specific data can be used to represent each performance of the vehicle to be measured.

Description

technical field [0001] The invention relates to a vehicle performance testing device, in particular to a four-wheel drive testing device and a testing method thereof. Background technique [0002] During the use of the car, with the prolongation of the use time (or the increase in mileage), its parts are gradually worn, corroded, deformed, aged, and the lubricating oil deteriorates, etc., resulting in a larger gap between the mating pairs, causing loose movement and vibration , sound and air leakage, water leakage, oil leakage, etc., resulting in a decline in the technical performance of the car. In order to ensure the safety of vehicles during use, general vehicles need to go to the designated vehicle inspection department for vehicle inspection (also known as annual inspection) at regular intervals. Only vehicles that pass the annual inspection can be allowed to continue on the road. A general two-wheel drive vehicle can be detected by a horsepower tester, that is, the dr...
