Description

Non-driving shaft wheel end fixing tool for automobile hub test Technical Field The utility model relates to an automobile whole performance test and detection auxiliary device, in particular to a non-driving shaft wheel end fixing tool for an automobile rotating hub test. Background The hub test is a common automobile performance test method in the development process of automobile products, and is mainly used for testing the power performance, the economic performance and other whole automobile performances of an automobile. The hub test is specifically to fix the automobile on a hub test stand and evaluate various performance indexes of the automobile by rotating wheels. The method can help automobile manufacturers to know the performance of the automobile, so that the design is optimized, and the driving experience and the safety are improved. The hub test bed is used as important whole vehicle performance test equipment, can conveniently and repeatedly perform hub tests under the same setting conditions, is little in external environment influence factor, is matched with an environmental cabin for use, and can simulate various natural environments for tests, so that the hub test shortens the product research and development period, accelerates the marketing of new products, saves the product development cost, plays an important role in improving various performances of vehicles, and is more and more favored by various automobile manufacturers. With the rapid development of domestic public transportation and logistics transportation industry, low-floor vehicle types are more and more favored by passengers and users due to the convenience in getting on and off passengers and the convenience in loading and unloading cargoes. However, when the hub is tested at present, the whole automobile is fixed on the hub test bench in a manner of adopting an iron chain or a steel rope to bind and fix the frame or the axle of the automobile, and the chassis of the low-floor automobile is too low, the periphery of the low-floor automobile is surrounded by a covering part, and the low-floor automobile is not provided with a reliable fixing point or even cannot be fixed in a conventional fixing manner, so that the test automobile is unstable, and the automobile shakes and aggravates during acceleration and deceleration of the automobile, so that great potential safety hazards exist. Disclosure of utility model Aiming at the problem that the low-floor vehicle type is inconvenient to fix in the hub test, the utility model provides the non-driving shaft wheel end fixing tool for the automobile hub test, which has the advantages of simple structure, reliable fixing and convenient installation and disassembly, and can effectively solve the problem that the non-driving shaft wheel end of the low-floor vehicle type is fixed. In order to solve the technical problems, the utility model adopts the following technical scheme: A fixed frock of non-drive axle wheel end for automobile hub test, its characterized in that includes flange board, intermediate junction spare, connecting seat, flange board, intermediate junction spare, connecting seat fixed connection in proper order, set up a plurality of first mounting holes that match with the bolt hole on the test vehicle rim on the flange board and be used for passing the second mounting hole of test vehicle shaft tip, the connecting seat includes two engaging lugs of relative setting, the one end fixed connection of two engaging lugs intermediate junction spare, the other end passes through the connecting rod and connects, the connecting rod with leave the joint gap between the intermediate junction spare.
