Embodiment Construction

[0023] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail:

[0024] figure 2 It is a schematic diagram of the structure of the CVT part of the test engine, image 3 yes figure 2 Partial enlarged view at A in the center, such as figure 2 with image 3 Shown, the CVT part of scooter engine comprises belt 9, roller hammer 10, roller hammer pressing plate 16 and belt pulley 13, and scooter engine bench test method of the present invention comprises the steps:

[0025] Step 1. Design and manufacture the auxiliary bushing 11 for the test, and select the test belt 12 for the test;

[0026] Step 2. The belt 9 and roller 10 of the CVT part of the test engine are removed, the test belt 12 is installed on the front and rear belt pulleys, and the auxiliary bushing 11 is installed between the roller hammer pressure plate 16 and the belt pulley 13. On the crankshaft, the belt pulley 13 is released to ensure th...

Abstract

The invention relates to a pedal motorcycle engine rack test method. An auxiliary lining is mounted between a rolling hammer pressure plate and a belt pulley, so a transmission ratio between a crank shaft and an output shaft of a pedal motorcycle engine is fixed, a performance test of the pedal motorcycle engine can be conveniently carried out by utilizing the fixed transmission ratio. A performance test of a pedal motorcycle engine rack in the prior art is carried out through an output shaft, multiple transmission ratios are needed to calculate according to different test points, so the pedal motorcycle engine rack test method solves problems of complex test process, long test period and high test cost existing in the prior art.

Description

technical field [0001] The invention relates to a test method for a scooter engine, in particular to a performance test method for a scooter engine bench test. Background technique [0002] At present, there are mainly two methods for the scooter engine bench performance test, one is to use the direct test at the crankshaft 1; the other is to indirect test at the output shaft 8 after calculating the transmission ratio through each test point. Such as figure 1 As shown, using the first method, when the crankshaft 1 is directly tested, in order to avoid damage to the dynamometer when the engine fails, it is usually necessary to design a gearbox 4, and the input end of the gearbox 4 passes through the shock-absorbing rubber sleeve I3 It is connected with the engine crankshaft 1 with the coupling I2; the output end of the gearbox 4 is connected with the dynamometer 7 through the shock-absorbing rubber sleeve II5 and the coupling II6. When using this method, the number of parts...
