Static torsion test device of wheel edge speed reducer

Abstract

The invention provides a static torsion test device of a wheel edge speed reducer. The static torsion test device comprises a half-shaft spline coupling device, an intermediate support device and a wheel edge coupling device. The half-shaft spline coupling device, the intermediate support device and the wheel edge coupling device are connected in sequence. The half-shaft spline coupling device is installed on a rotating shaft end surface on an equipment torque output end and is used for being connected with a test piece half shaft and a half shaft on a wheel edge speed reducer assembly, and the half shaft is enabled to rotate, so that a wheel edge speed reducing mechanism is driven to rotate, and the wheel edge speed reducing mechanism is a torsion generating source. Torque is formed by restriction relations generated among the half-shaft spline coupling device, the intermediate support device, the wheel edge coupling device and a test piece, so that the static torsion test function is realized. According to the invention, static torsion intensity examination is carried out on the wheel edge speed reducer and an axle housing body shaft head part, supports are provided for exploitation and quality improvement of chassis products, and the test method and device can be widely applied to production enterprises of wheel edge speed reducing axles.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an axle test technology, which is applied to the static torsion test of a wheelside reducer of a wheelside bridge, and provides a set of static torsion test devices for the wheelside bridge. Background technique [0002] The invention focuses on the static torsion test of the wheel side of the wheel bridge, and is a new type of test device, which is invented and proposed for the first time. [0003] Conventional wheel-side bridge assembly tests usually use methods such as bridge assembly fatigue life test and axle housing fatigue life test. Under the actual working conditions of the axle, the product failure forms are diversified. In addition to the fatigue damage of the gear, it is accompanied by the torsion damage of the shaft head, the breakage of the half shaft, and the fragmentation of the wheel reducer. The conventional test method cannot reflect the product’s resistanc...

Problems solved by technology

Under the actual working conditions of the axle, the product failure forms are diversified. In addition to the fatigue damage of the gear, it is accompanied by the torsion damage of the shaft head, the breakage of the half shaft, and the fragmentation of the wheel reducer. The conventional test method cannot reflect the product’s resistance. Torsional destructive ability, for this reason, propose this method and device

[0004] Existing technology: a torque loading test device for wheel-side reducer, which only tests the component group, not the wheel-side reducer assembly; the second is that the test device is different, because the transmission principle and product structure of the wheel-side reducer assembly are complicated, so When realizing the assembly test, the test device is also relatively complicated, and the static torsion test function can only be realized by the cooperation of several sets of mechanisms. However, in the prior art, because the product is only a single transmission form between the planetary gear and the ring gear, there is no need to complex testing mechanism to achieve
