Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] The present invention provides a method for testing the transmission link power flow of the integrated transmission device of a road test vehicle. According to the design and calculation instructions, the relationship between the components of the integrated transmission device is simplified, and the block diagram of the components of the integrated transmission device is obtained. See figure 1 . The transmission link of the integrated transmission is determined by the block diagram of the components of the integrated transmission and the working conditions of the gears.

[0024] The power flow of the transmission link of the integrated transmission device determines the power flow direction of each transmission link according to the structure of the transmission link and the components of each transmission link. The backbone of the transmission li...

Abstract

The invention discloses a method for testing the power flow of a transmission link of a comprehensive transmission device of a road test vehicle, belonging to the technical field of vehicle testing. The test method first selects the torque measuring points and speed measuring points of the trunk and branches in the internal transmission link of the vehicle transmission; Rotational speed; the transmission power flow of the transmission link of the transmission device is obtained by converting the product of the torque and the rotational speed at the same moment. The invention can solve the real-time test problem of the transmission link power flow of the vehicle transmission device during the actual vehicle road test.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a real-time testing method for power flow of a transmission link of a vehicle road test transmission. Background technique [0002] The transmission power flow of the comprehensive transmission device of the vehicle transmits the power of the power device to the drive device. Through the characteristics of power transmission, torque and speed expansion, functions such as forward, backward, acceleration, climbing, and steering of the vehicle are realized. Through the study of power flow, the power loss of the transmission can be effectively reduced, the net power can be increased, and the flow direction and size distribution of the power flow of the transmission link can be controlled to improve various performance indicators of the vehicle without affecting the performance of the engine. [0003] For many years, vehicle designers have conducted a lot of research on the de...
