Problems solved by technology

[0006] However, in the method shown in Patent Document 1, the movement of the test vehicle is time-consuming and troublesome. In the method shown in Patent Document 2, although it is simpler than using a tractor tow, the mechanical strength of the key is weak, and the force from the engine cannot be adjusted. Powerful
Therefore, in the method shown in Patent Document 2, the test vehicle can only be moved at a slow speed, and it is difficult to make the moving distance long

Embodiment Construction

[0045] Hereinafter, an embodiment of the vehicle test system of the present invention will be described with reference to the drawings.

[0046] The vehicle test system 100 of this embodiment is used to test the performance of the engine or transmission of the test vehicle V, for example, specifically, figure 1 As shown, it includes: a simulated wheel 10 connected to the axle S of the test vehicle V; a dynamometer 20 connected to the simulated wheel 10 from the opposite side of the axle S; a torque sensor not shown, which detects the direction of the axle S Applied torque; and an exhaust gas analysis device not shown that analyzes the exhaust gas of the test vehicle V.

[0047] In addition, the test vehicle V can be a two-wheel drive vehicle of FF or FR, or a four-wheel drive vehicle.

[0048] Such as figure 1 As shown, the simulated wheel 10 has: a rotating connection portion 11 connected to the axle S to support the axle S so as to be rotatable; and a tire 12, which remains station...

Abstract

The invention provides a vehicle test system, a method for moving a test vehicle and a simulated wheel. In order to make it possible to move a test vehicle (V) easily by using a big power in case of moving the test vehicle (V) accompanying a vehicle test by the use of a simulated wheel (10), the vehicle test system comprises a dynamometer (20) that gives a load to the test vehicle (V); a simulatedwheel (10) having a rotary connection part (11) to one side of which the dynamometer (20) is connected and to the other side of which a vehicle shaft (S) of the test vehicle (V) is connected in caseof testing the test vehicle (V) and that does not transmit a rotation of the vehicle shaft (S) to a tire; and a wheel for driving (40) that is connected to the rotary connection part (11) from which the dynamometer (20) is dismounted and to which the rotation of the vehicle shaft (S) is transmitted in case of moving the test vehicle (V).

Description

Technical field [0001] The invention relates to a vehicle test system, a test vehicle movement method and a simulated wheel. Background technique [0002] In the past, as a vehicle test system that applied a load from a dynamometer to the axle of a test vehicle for testing, in order to simulate the state of the actual vehicle driving, the simulated wheels were connected to the axle of the test vehicle and the suspension and shock absorbers were used. Test under the state of operation. [0003] The above-mentioned simulated wheel is configured such that the tire connected to the axle rotates without rotating the tire. According to the above configuration, when it is desired to move the test vehicle, even if the simulated wheels are connected to the axle, the power transmitted from the engine to the axle is not transmitted to the tires in the above state, and the test vehicle cannot be moved. [0004] Therefore, as a method of performing a vehicle test using simulated wheels and movi...
