Abstract

The invention belongs to automobile performance testing equipment, and aims to fill a gap in an automatic testing field for the inter-shaft sideslip of a double-steering-shaft automobile, and furthermore realizes simultaneous testing for the inter-wheel sideslip and the inter-shaft sideslip of the double-steering-shaft automobile. The invention provides a testing platform and furthermore provides an integrated testing device for the inter-wheel sideslip and the inter-shaft sideslip of the double-steering-shaft automobile. A tested automobile is driven on the device, and an automobile frame is fixed by two automobile fixing device assemblies. Automobile steering wheels are driven to rotate through a floating road surface simulating mechanism in the testing platform. Side forces which are generated in rotation of the automobile steering wheel are transferred to two side force testing sensors through the floating road surface simulating mechanism, thereby testing the side force of each automobile steering wheel, making technological personnel adjust a transverse pull rod and a longitudinal pull rod of the automobile in a targeted manner according to a testing result, determining a reasonable positioning parameter of the automobile, satisfying Ackermann steering geometry, and finishing testing and adjustment on the side force of the steering wheels of the automobile.

Description

technical field [0001] The invention belongs to automobile performance detection equipment, in particular to an integrated detection device for side slip between wheels and between axles of a double steering shaft automobile. Background technique [0002] Our country has not yet made relevant regulations on the amount of side slip of the wheels caused by the failure of the two steering shafts of the dual-steering shaft steering system, that is, the amount of side slip between axles. The side slip of the wheel is the side slip between the wheels, and the "Technical Conditions for Motor Vehicle Operation Safety" has detailed regulations. [0003] For the design and research of the steering mechanism with double steering shafts, a lot of work has been done on theoretical analysis at home and abroad, but the actual application technology is not yet mature. As far as we know, there are very few studies on the theory of sideslip detection between two steering axles, let alone pra...
