Embodiment Construction

[0009] like figure 1 As shown, the present invention provides a front-drive dynamometer, which is used to detect the power of the two output half shafts of the front-drive transmission 1. The front-drive transmission 1 has a first output half-shaft 11 and a second output half-shaft 12. The front-drive dynamometer The device includes a dynamometer 2 and a transmission mechanism 3 .

[0010] Wherein, the dynamometer 2 is installed at the end of the second output shaft 12 , and the dynamometer 2 also includes a weighing device 21 and a rotational speed sensor 22 .

[0011] This transmission mechanism 3 comprises two output semi-shaft synchronizing wheels 31 respectively installed at the ends of the first output semi-shaft 11 and the second output semi-shaft 12, a drive shaft 33 erected between the two bearings 32, respectively installed on the The transmission shaft synchronous pulley 34 at both ends of the transmission shaft 33, and the synchronous transmission belt 35 wound be...

Abstract

The invention relates to a predecessor dynamometer equipment. It includes a dynamometer machine mounted on the tail end of second output semishaft of predescessor speed changer and a transfer mechanism. Said transfer mechanism also includes two output shaft synchro-wheels respectively mounted on the tail end of first output semishaft and tail end of second output semishaft of said predecessor speed changer, a transmission shaft, transmission shaft synchro-wheels respectively mounted on two tail ends of said transmission shaft and synchro-belt which is winded and positioned between output shaft synchro-wheel and transmission shaft synchro-wheel of same side, in which the transmission ratio between two output shaft synchro-wheels is 1.

Description

【Technical field】 [0001] The invention relates to a transmission detection device, especially a front drive dynamometer. 【Background technique】 [0002] At present, in the development and maintenance of automobiles, it is often necessary to test the automatic transmission. In order to detect the output power of the automatic transmission, a dynamometer specially developed to detect the output power of the automatic transmission has been developed. [0003] Due to the characteristics of the car's own structure, the current front-drive automatic transmission has two output shafts, while the rear drive has only one output shaft. In this way, when testing the power of the front drive, the current practice is to install a dynamometer on each of the two output axle shafts of the front drive, but when testing the automatic transmission of the rear drive, only one dynamometer is needed, which increases the The production cost of the equipment is increased, and the length and floor ...
