AI Technical Summary
When conducting the fatigue test of the front axle gear, the prior art is difficult to simplify the fixed tooling of the vehicle frame, resulting in the complex design of the test tooling and it is difficult to restore the stress state of the front axle on the entire vehicle.
Design a tool clamp that imitates the installation and fixing method of the vehicle front axle, including the base plate, main reduction part lifting point tooling and imitating the steering knuckle wheel edge fixing tooling. Through these components, these components imitate the fixing method of the vehicle front axle on the vehicle to simplify the test Workwear design.
The simplified test tooling design is realized, which can truly imitate the stress state of the front axle on the frame, and solves the frame fixation problem in the front axle-related test.

Abstract
Description
Technical Field
[0001] The utility model relates to a fixing tool for a front axle in a fatigue test of a front axle gear of an automobile, in particular to a tool fixture for imitating the installation and fixing mode of the front axle of the automobile. Background Art
[0002] When developing the front axle, in order to verify the comprehensive performance of the front axle gear, bench verification is necessary. Since the front axle only bears torsion but not load, the front axle is hung on the frame. When conducting the front axle bench test, the frame and the front axle are fixed and placed on the test bench for relevant tests. Since the frame is too large, a simple fixture is urgently needed to replace the frame. Utility Model Content
[0003] The utility model aims to solve the defects in the prior art and provide a tooling fixture for a front axle of an automobile which imitates the installation and fixing mode of a whole vehicle.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A tooling fixture for imitating the installation and fixing method of a whole vehicle on a front axle of an automobile, comprising a bottom plate, a main reduction part hanging point tooling arranged on the bottom plate, and imitating steering knuckle wheel edge fixing tooling arranged on both sides of the main reduction part hanging point tooling, the main reduction part hanging point tooling comprising a guide column installed on the bottom plate, a cross arm sleeved on the guide column, and a locking bolt is arranged on the guide column;
[0006] A suspension arm is arranged at the end of the horizontal arm, and a positioning bolt is arranged on the suspension arm.
[0007] Furthermore, the imitation steering knuckle wheel edge fixing tool comprises a positioning seat arranged on one side of the base plate and a positioning sleeve arranged on the positioning seat.
[0008] Furthermore, the bottom of the cross arm is connected to the support plate, and the end of the support plate is fixedly connected to the bottom plate through a support seat.
[0009] Furthermore, a lower support is provided on the bottom plate at one side of the guide column.
[0010] Furthermore, the top of the base plate is suitable for installing the front axle, the wheel edges at both ends of the front axle are connected to the positioning sleeves, the upper part of the front axle is supported by the positioning bolts on the boom, and the bottom of the front axle is supported by the lower support.
[0011] The beneficial effects of the utility model are as follows: the application solves the problem that the frame is required for the front axle related tests. This structure truly imitates the fixing method of the front axle on the whole vehicle, simplifies the design of the test tooling, and can well restore the stress state of the front axle on the frame. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1It is a schematic diagram of the assembly structure of the utility model and the front axle lifting and fixing method. DETAILED DESCRIPTION
[0013] Reference Figure 1 A tooling fixture for a front axle of an automobile that imitates the installation and fixing method of a whole vehicle includes a base plate 1, a main reduction part hanging point tooling arranged on the base plate 1, and imitation steering knuckle wheel side fixing tooling arranged on both sides of the main reduction part hanging point tooling. The main reduction part hanging point tooling includes a guide column 2 installed on the base plate, a cross arm 3 sleeved on the guide column 2, and a locking bolt 4 is provided on the guide column 2; a hanging arm 5 is provided at the end of the cross arm 3, and a positioning bolt 6 is provided on the hanging arm 5.
[0014] Furthermore, the imitation steering knuckle wheel edge fixing tooling includes a positioning seat 7 arranged on one side of the base plate 1, and a positioning sleeve 8 arranged on the positioning seat 7; the bottom of the cross arm 3 is connected to the support plate 9, and the end of the support plate 9 is fixedly connected to the base plate 1 through the support seat 10, and a lower support 11 is provided on the base plate 1 on one side of the guide column 2.
[0015] When the fixture is in use, the front axle 12 is hoisted on the main reduction part lifting point fixture, and the wheel edge 13 is fixed on the imitation steering knuckle wheel edge fixture. Specifically, the wheel edges 13 at both ends of the front axle 12 are connected to the positioning sleeves 8, the upper part of the front axle 12 is supported by the positioning bolts on the boom 5, and the bottom of the front axle 12 is supported by the lower support 11.
[0016] The suspension arm 5 on the cross arm 3 adopts a waist-shaped hole, and the lower support can be adjusted and moved, which can simplify the difficulty of aligning and installing the three fulcrums of the front axle at the same time. At the same time, by replacing the suspension arm 5 and the lower support 11, it can be applied to the installation and testing of a series of front axles.
[0017] This application solves the problem that the frame is required for front axle related tests. This structure truly imitates the fixing method of the front axle on the whole vehicle, simplifies the design of the test tooling, and can well restore the stress state of the front axle on the frame.
[0018] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent shape or structural transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
