Embodiment Construction

[0031] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0032] figure 1 , figure 2 , image 3 with Figure 4 The hub test bench includes hub bending fatigue test bench and hub radial fatigue test bench. Such as figure 1 with figure 2 As shown, in the wheel hub bending fatigue test, the wheel hub bending fatigue test bench is used. The wheel hub bending fatigue test bench includes two reaction seats 1 arranged on the same horizontal line, and one of the reaction seats 1 is set on the end face There is a shaft tube mounting plate 2, the flange end face of the shaft tube 3 is connected with the shaft tube mounting plate 2 and fixed vertically on the reaction seat 1; On the force arm plate 6, the installation of the wheel hub assembly 4 and the shaft tube 3 conforms to the torque specified in the design drawings. Tighten the wheel hub bearing fastening nuts, the tire bolt distribution circle of the wheel hub mounti...

Abstract

The invention discloses a hub test bench and a hub test method, a hub bending fatigue test bench comprises a shaft tube mounting plate arranged on the end face of a counterforce seat, the shaft tube mounting plate is connected with a shaft tube, and the lower end of a force arm plate is provided with an adjusting plate; the front end of the oil cylinder assembly is connected with the adjusting plate, and the rear end is connected with the counter-force seat; a force sensor is arranged between the adjusting plate and the oil cylinder assembly, and the sensor and the oil cylinder assembly form a force loading unit to load horizontal force on the force arm plate; a counter-force seat is additionally arranged on the hub radial fatigue test bed on the basis of a hub bending fatigue test bed, and a hub fixing plate used for installing a hub assembly half shaft is arranged on the counter-force seat. The hub test method comprises the following steps: determining each test parameter, testing on a test bed, and performing failure judgment. According to the invention, the problems of poor stability of the whole wheel, influence on the traceability of the hub test, influence on the development progress of a new product, high test difficulty and the like in the existing hub test can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a test bench and a test method for quickly detecting automobile wheel hubs. Background technique [0002] From January 1, 2020, the national standard GB36581-2018 "Automotive Wheel Safety Performance Requirements and Test Methods" will be officially implemented. Wheel "wheel dynamic bending fatigue test method" and "wheel radial fatigue performance test method" only define and require the assembly of the wheel assembly. However, as a direct fitting assembly, the wheel hub has no relevant standards. During the test, the wheel hub test is often carried out with reference to the "Automotive Wheel Safety Performance Requirements and Test Methods". The wheel hub needs to be assembled into the wheel during the test, so the wheel hub test must ensure the overall stability of the wheel. Once there is a problem with the tire or rim, it will not only affect the traceabili...
