Self-correct guide front wheel mechanism of rail guide vehicle for installing commercial vehicle rear axle assembly line

Abstract

The invention discloses a self-correct guide front wheel mechanism of a rail guide vehicle for installing commercial vehicle rear axle assembly lines. The mechanism comprises a vehicle front wheel which is connected with an axle in a rotation manner, an inverted U-shaped seat is movably connected to the axle, a rotating shaft is vertically and fixedly connected to the top of the inverted U-shaped seat, a connecting seat fixedly connected to a vehicle baseplate is connected to the rotating shaft in a rotation manner, and a plumb line where the center of the front wheel locates is not superposed with the central line of the rotating shaft. Aiming at the requirement that the front wheel of the rail guide vehicle needs to be parallel with the travelling direction during the travelling of the vehicle, the invention adopts the design that central line of a steering shaft and that of the front wheel are offset, so that during travelling, the direction of the front wheel playing a guiding role can be self-corrected and be parallel with the traveling direction of the vehicle, so as to improve the travelling reliability of the vehicle. In addition, the mechanism has the advantages of excellent manufacturing techniques, convenience in adjustment, high bearing capacity, high safety and reliability and long service life.

Description

Technical field: [0001] The invention relates to a self-correcting guiding front wheel mechanism of a trolley on a rear axle assembly line of a commercial vehicle. Background technique: [0002] In the assembly line of the automobile rear axle, one of the assembly methods is to place the rear axle housing (assembly reference part) on the assembly trolley, and the assembly trolley moves between stations to meet various assembly requirements. At present, the means of transportation between the workstations on the rear axle assembly line mostly use the Rail Guide Vehicle (Rail Guide Vehicle), which is a means of transportation that walks along the guide rail, and has two driving modes: self-driven and other-driven. The self-propelled trolley uses four rechargeable batteries loaded on the RGV as the power source, and a guide bearing is installed on the chassis of the RGV. Move along the groove. However, due to the large guiding resistance of the front guide wheels of existing ...

AI Technical Summary

Problems solved by technology

However, due to the large guiding resistance of the front guide wheels of existing trolleys, the steering of the wheels cannot be self-corrected according to the direction of travel, and the bearing capacity is poor (because the rear axle of a commercial vehicle can weigh up to 2 tons), which leads to the movement of the assembly trolley. Inflexible, reducing the efficiency of assembly work
