Expansion water tank integration device for passenger car with rear engine

Abstract

The invention discloses an expansion water tank integration device for a passenger car with a rear engine. The expansion water tank integration device comprises an expansion water tank bracket and a car-frame transverse beam, wherein the car-frame transverse beam is fixedly mounted on the outer lateral side of a car frame and perpendicular to car-frame longitudinal beams; the expansion water tank bracket consists of a clamping head and a supporting frame which are fixedly connected; the supporting frame is mounted on the car-frame transverse beam. The expansion water tank integration device is characterized in that the supporting frame bends towards the tail of the passenger car so as to reserve a water adding position for an expansion water tank; a plurality of holes are formed in the supporting frame and used for fixing a pipeline. The expansion water tank integration device has few components, and is simple in structure and convenient to manufacture and process; the expansion water tank integration device is light in weight, and conforms to the design trend of light weight; the expansion water tank integration device is high in strength and rigidity, sufficient in hold-hoop pretightening force, and firm and reliable in fixation; the expansion water tank integration device is fixed on the car frame through the bolts, so that the expansion water tank integration device is convenient to mount, demount and connect; the expansion water tank integration device has few fixed points which need to be fastened, few mounting procedures are needed, and the working time is short; the expansion water tank is favorable for shortening production time and improving production efficiency, and is low in cost.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an expansion water tank integration device for a passenger car with a rear engine. Background technique [0002] In the current installation process of the rear-engine passenger car frame assembly, when the chassis assembly goes off the assembly line and goes to the next process, the expansion tank is bound to other components of the chassis with cable ties and placed temporarily. The expansion water tank needs to wait for the chassis assembly and the body assembly to be assembled into a complete vehicle before it can be installed on the bracket reserved for the rear compartment of the body. [0003] Due to reasons such as poor fixation of the expansion tank and lack of protection measures during the process flow, it is easy to cause misuse and damage to the expansion tank during construction, and it is prone to missing installation. In addition, it is necessary to organize and install...

AI Technical Summary

Problems solved by technology

[0003] Due to the unstable fixing of the expansion water tank and the lack of protection measures during the process flow, it is easy to cause misuse and damage to the expansion water tank during construction, and it is prone to leakage.

In addition, it is necessary to organize and install the expansion tank many times, which increases the man-hours and increases the manufacturing cost.
