Embodiment Construction

[0023] Combine below Figure 1 to Figure 3 , the present invention is further described:

[0024] Such as figure 1 As shown, a quick-change device for an engine test bench includes a quick-change trolley 2 , an adjustable outrigger 3 , a centering device 5 , a dynamometer 6 , a pressing device 7 and a positioning base 8 . Among them, the dynamometer 6, the pressing device 7 and the positioning base plate 8 are fixed on the installation base plate 1, the engine 4 is fixed on the quick-change trolley 2 through the adjustable outrigger 3, and the engine 4 is connected to the quick-change trolley 2 through the centering device 5. For centering, the quick-change trolley 2 is centered with the dynamometer 6 through the positioning base plate 8 .

[0025] The centering device 5 is used to align the position between the quick-change trolley 2 and the engine 4. The quick-change trolley 2 includes the position adjustment and fixing device of the engine, and has shock-absorbing ability...

Abstract

The invention relates to a quick change device of an engine test bed, which comprises a quick change trolley (2), adjustable legs (3), an aligning device (5), a dynamometer (6), a clamping device (7) and a positioning base plate (8), wherein the dynamometer (6), the clamping device (7) and the positioning base plate (8) are fixedly on an installation base plate (1), the quick change device is characterized in that the an engine (4) is fixed on the quick change trolley (2) by the adjustable legs (3) and is aligned to the quick change trolley (2) by the aligning device (5), and the quick change trolley (2) is aligned to the dynamometer (6) by the positioning base plate (8). By the quick change device, the engine can be quickly positioned, and the dynamometer can be quickly aligned and connected.

Description

technical field [0001] The invention relates to a quick-change device for an automobile engine test bench. Background technique [0002] The rapid replacement, alignment, connection and fault pretreatment of the engine to be tested are the key factors restricting the utilization rate of the engine performance bench. It often takes 1-2 days for an engine to prepare for the test and enter the test state normally. Moreover, once the engine installed on the bench has a fault, it needs to be re-prepared. This is an urgent breakthrough for all automobile manufacturers. technical challenge. [0003] AVL, BOSCH and other internationally renowned engine research and development institutions also have similar products, but they are not suitable for promotion and use in major OEMs due to problems such as complex structure, low efficiency, and high manufacturing cost. Contents of the invention [0004] The invention designs a quick-change device for an engine test bench, which solve...
