Abstract

The invention discloses a hydrodynamic retarder type load simulation vehicle. The hydrodynamic retarder type load simulation vehicle comprises a vehicle body; an engine, a total controller, a torque sensor, a first hydrodynamic retarder, a second hydrodynamic retarder, a transmission, and a retarder heat dissipation system. The torque sensor and the first hydrodynamic retarder are disposed between the engine and the transmission, and the second hydrodynamic retarder is disposed on the output end of the transmission. The retarder heat dissipation system is close to the first hydrodynamic retarder, and the controller is connected with the torque sensor, the first hydrodynamic retarder, the second hydrodynamic retarder, and the retarder heat dissipation system. The hydrodynamic retarder type load simulation vehicle is advantageous in that compared with a load trailer, the load simulation vehicle has stronger maneuverability and operation stability, and wear of a test vehicle brake system is reduced.

Description

Technical field [0001] The invention relates to a vehicle load simulation system, in particular to a hydraulic retarder type load simulation vehicle. Background technique [0002] In the development process of automobile transmission system and engine, automobile road test is an indispensable link. Among them, automobile performance and reliability tests are an important part of automobile road tests. For a long time, the reliability and power test of the automobile need to carry out a large number of tests to verify its performance, and the test cycle is long and requires a lot of manpower and material resources. [0003] The existing vehicle test load simulation method is mainly based on the load trailer, that is, the test vehicle is used to tow the trailer with the simulated load to carry out the vehicle test. [0004] For example, the Chinese Patent Authorization Announcement Number CN203908783U describes a semi-trailer load trailer. Install dynamometer, transfer case, generat...
