Embodiment 1

[0028] by attaching figure 1 It can be seen that the present invention relates to a full-load passenger car power assembly assembly car, comprising a main frame 1 and a sub-frame 2, a scissor assembly 3 is arranged between the main frame 1 and the sub-frame 2, and a scissor assembly 3 is arranged under the main frame 1. Road wheel 4 is installed, and it is characterized in that, described road wheel 4 is 5, and a road wheel is the main drive wheel 5 with power drive, is provided with operating lever on the main frame above main drive wheel 5 10. There is a lifting cylinder 6 between the main frame 1 and the sub-frame 2, and the lifting cylinder 6 drives the scissor assembly 3 to move, so that the sub-frame 2 is lifted relative to the main frame 1; The horizontal adjustment mechanism 7 and the floating adjustment mechanism 8 are accurately adjusted through the horizontal adjustment mechanism 7 and the floating adjustment mechanism 8, so that the powertrain of the full load-bear...

Embodiment 2

[0035] Embodiment 2 is basically the same structure as Embodiment 1, except that the structure of the lifting cylinder is different. Double lifting cylinders are used. It is connected to the end of the side frame of the main frame, and the other end is connected to the middle of the sub-frame, and the sub-frame is raised by double lifting cylinders.

Embodiment 3

[0037] Embodiment 3 has basically the same structure as Embodiment 1 or 2, except that the structures of the horizontal adjustment mechanism and the floating adjustment mechanism are different. The horizontal adjustment mechanism is a double horizontal guide rail mechanism, and the double guide rails are respectively arranged on the inner surface of the sub-frame. The middle position of the frame connection point, the distance between the two guide rails is 800-1000mm; and the front two of the four traveling wheels are fixed traveling wheels, and the rear two are cantilever rotating wheels. With the rotation of the direction of motion of the main driving wheel, it is more convenient for the steering of the trolley.

Abstract

An assembling method for a full-bearing bus power assembly is characterized that the full-bearing bus power assembly is arranged on an assembling cart platform driven by a motor by adopting a self-traveling and mechanical operation lifting mode, and the full-bearing bus power assembly is conveyed to be under a vehicle frame through a self-traveling device, then lifted to a proper position through a hydraulic lifting mechanism, and accurately adjusted through a hydraulic-controlled transverse adjustment mechanism and a floating adjustment mechanism, so that the full-bearing bus power assembly is accurately installed on the vehicle frame. A full-bearing bus power assembly assembling cart is powered by a storage battery. After charging, a tool can realize the three-dimension motions of vertical lifting, left-right transverse movement and front-back travelling through a control handle, angle floating micro adjustment can be conducted, and positioning and adjustment in the assembling process are facilitated. The installation problem of the full-bearing plug-in bus power assembly is effectively solved through the tool, and the installation efficiency is greatly improved.

Description

technical field [0001] The invention relates to an operation method and tools for automobile manufacturing, in particular to an assembly method and tooling for a full load-bearing passenger car power assembly, which belongs to the technical field of automobile manufacturing and is mainly used in the assembly operation of the passenger car power assembly. Background technique: [0002] The fully loaded passenger car is one of the safest passenger cars in my country at present. The full load-bearing structure makes the driving of the bus more agile, stable, comfortable and safe, coupled with its advantages of low-floor design, humanized configuration, low emission, environmental protection, and large passenger space, it reflects the modern The concept of "leading technology, people-oriented" advocated by the society has also created the unique product advantages of full-carrying buses. The full load-bearing body technology applied to passenger cars is an important item in the...
