Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Please refer to figure 2 , figure 2 It is a structural schematic diagram of a specific embodiment of the test device for engine starting characteristics provided by the present invention.

[0036] Such as figure 2 As shown, the test device includes a base 100, a flywheel 200 fixed to the base 100, the flywheel 200 is driven by a starter 400, the flywheel 200 and the starter 400 are fixed relative to the base 100, and the two can be respectively They are connected to the base 100 by respective fixing devices, and may also be connected to the base 100 through the same fixing device. During the starting process of the engine, the starter 400 is affected by the force from the following two aspects: the frictional...

Abstract

The invention discloses a device for testing the starting characteristic of an engine. The device comprises a base, a fly wheel fixed to the base and a first loading device loading the constant torque to the fly wheel and further comprises a second loading device loading the waveform torque to the fly wheel. The constant torque exerted through the first loading device is combined with the waveform torque exerted through the second loading device and the constant torque and the waveform torque are commonly exerted on the fly wheel, so that the force receiving condition of the fly wheel is quite similar to the real condition, and therefore the starting characteristic of the engine can be reasonably simulated.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a test device for engine starting characteristics. Background technique [0002] The engine usually cooperates with the starter, and the flywheel of the engine meshes with the gear of the starter, and the gear of the starter drives the flywheel to rotate to realize the starting of the engine. [0003] The flywheel of the engine is covered with a ring gear, and the gear of the starter is meshed with the ring gear, and then the torque of the starter is transmitted to the flywheel and the crankshaft of the engine, and finally drives the piston of the engine to move in the cylinder. [0004] In order to assess the starting characteristics of the engine, such as the force condition of the starter, the meshing condition of the ring gear and the starter gear, and the durability of the ring gear, there are two typical test methods as follows: [0005] The first is to test in the actual ...
