ABSTRACT:
TECHNICAL FIELD
This invention relates generally to engine mounts for mounting an engine/powertrain onto a chassis of an automobile, and more particularly to an engine mount with vertical alignment for accomplishing same.
DISCUSSION
Generally speaking, the process of mounting an automobile engine which includes the engine and transmission (the powertrain assembly) is from underneath the vehicle. In the conventional manner, the mounting of an engine is carried out by the mating of mounting components wherein the engine is brought up to a specified height, the mounting components are appropriately aligned and thereafter fasteners and/or bolts are used to tighten the mounting components. In the conventional use of spool mounts for example, the bolting that is required is carried out in at least two positions, in a horizontal direction wherein a pair of cantilevered bolts extend from two substantially opposite positions of the chassis requiring the operator to control the fore/aft, cross car and vertical axes when inserting the engine. In conventional applications the fore/aft and cross car axes are more easily controlled in the engine insertion process, with the vertical axis being more difficult to control and therein, being prone to result in failure upon insertion due to vertical tolerances which require more precise insertion parameters. As a result of these vertical tolerances an unacceptable first time capability (FTC) results therein leading to higher costs both in labor and time. Additionally, because of the position of the horizontal cantilevered bolts, further difficulties result in component failure due to bad joints and from the cantilevered bolts being in shear once the engine is mounted.
Accordingly, it is therefore desirable to provide an engine mount with vertical alignment that can alleviate the above-referenced difficulties.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an engine mount with vertical alignment to improve first time capability.
It is a further object of the present invention to provide an engine mount with vertical alignment that reduces production costs both in time and labor.
It is a further object of the present invention to provide an engine mount with vertical alignment that reduces material costs.
It is a further object of the present invention to provide an engine mount with vertical alignment that removes the tolerances both on engine placement and on decking.
It is a further object of the present invention to provide an engine mount with vertical alignment that reduces failure.
It is a further object of the present invention to provide an engine mount with vertical alignment that removes the necessity to vertically align the powertrain assembly prior to decking.
These and other objects and advantages of the invention are obtained by providing an engine mount with vertical alignment for mounting a powertrain member on a chassis of a vehicle. The engine mount with vertical alignment has a mount body which has a hollow core for housing a metal core. The metal core has at least one channel for accepting a vertically placed bolt, the metal core being held in position by a rubber mount. The metal core interfaces with a mounting bracket that is connected to a powertrain member for vertical mounting onto a chassis.
