ACTIVE RESISTANCE DYNAMOMETER FOR WHEEL TESTING

摘要

A wheel testing system and method are provided that simulates realistically conditions likely to be encountered during operation of vehicle wheels, especially powered drive wheels and wheel-connected structures. The system may include an integral support frame designed to adjustably mount wheels or wheel-connected structures to be tested, a load motor drivingly connected to an inertial load, and an adjustable mounting sled configured to adjustably mount a test wheel or a wheel-connected structure with an hydraulic system actuatable to adjust the location of the test wheel relative to the inertial load to vary or fix the load on the test wheel desired. Speed of the test wheel can be varied or fixed by controlling the speed of the load motor. System measurement and data collection electronics measure a range of selected wheel parameters and gather data for transmission to a processor or non-transitory storage medium for processing and evaluation.

1. A dynamometer system for testing selected functional and operational parameters of vehicle wheels and wheel-connected or wheel-related structures and functions comprising:
a. adjustable sled means for adjustably mounting one or more structures comprising a wheel, a wheel-connected structure, or a wheel-related structure in a selected test position; b. variable load application means for applying a fixed or variable load to said one or more structures in said selected test position; c. variable drive means for driving a rotating component of said variable load application means to drive said one or more structures at a fixed or variable speed, wherein either or both of the variable load application means and the variable drive means is actuatable to vary load and speed as required to test selected functional and operational parameters of said one or more structures; and d. support frame means for operationally mounting said adjustable sled means, said variable load application means, and said variable drive means.
