Description

Technical Field

[0001] The invention relates to the technical field of automobile adjustment tools, in particular to a vehicle suspension height measuring tool. Background Art

[0002] The utility model with application number CN201821933854.5 discloses a vehicle suspension height measuring tool, including: a ruler, a caliper, a fixed disc and a plurality of sleeves; the fixed disc is connected to the wheel of the vehicle through a plurality of sleeves; one end of the ruler is connected to the center of a plane on one side of the fixed disc and extends along the vehicle suspension height direction; the caliper is movably sleeved on the other end of the ruler and can reciprocate within the vehicle suspension height. The utility model solves the problem of poor adaptability of the measuring tool by adopting a sleeve that can move on the fixed disc, so that it can be used on vehicle suspensions of various specifications, thereby improving the scope of use and versatility; by adopting a ruler with precise scales and a caliper that can accurately read the ruler value, the problem that the measuring tool can only judge the range but cannot accurately read the value is solved, thereby improving the accuracy of suspension adjustment and improving the overall performance of the vehicle.

[0003] The specification of the patent document states that "the number of sleeves 4 is 4, 5 or 6. The number of sleeves 4 installed on the fixed disc 3 can be determined according to the number of fastening screw holes of the vehicle wheel hub, which improves the applicability of the measuring tool to the vehicle." That is to say, in actual use, the sleeve needs to be sleeved on the fastening bolts of the vehicle wheel hub to achieve positioning between the entire device and the vehicle. Although the new sleeve can move radially along the fixed disc to adapt to different types of wheel hubs, the number of fastening bolts of each type of wheel hub is inconsistent, and the angle between the fastening bolts and the center line of the wheel hub will be different. Therefore, even if the new sleeve can move radially along the fixed disc, it cannot adapt to all types of wheel hubs; and when the new type is connected to the vehicle wheel hub, it is necessary to operate each sleeve, and its operation method is cumbersome and the work efficiency is low.

Under the extension and retraction of the telescopic rod, the arc-shaped clamping plate 12 moves back and forth radially along the center hole 11.

[0032] In this embodiment, the telescopic rod can be an electric push rod, and the arc-shaped clamping plate 12 can be moved radially under the extension and retraction of the electric push rod, so that it can be adapted to various types of wheel hubs.

[0033] Example 4

[0034] like Figure 1 , 2As shown, the telescopic rod includes a bearing seat 10, a screw 8, and a nut pair 7. The outer surface of the fixed disc 1 is provided with a bearing seat 10, and a radial bearing 9 is provided in the bearing seat 10. The inner ring of the radial bearing 9 is fixedly connected to one end of the nut pair 7 by a connecting rod. The screw 8 passes through the inner ring of the radial bearing 9 and the nut pair 7. The screw 8 is threadedly connected to the nut pair 7. The outer surface of the screw 8 is clearance-matched with the inner surface of the inner ring. The outer end of the screw 8 is slidably connected to the outer surface of the fixed disc 1 through a slider (a commonly used structure, not shown in the figure). The nut pair 7 is rotated to realize the radial extension and retraction of the screw 8 along the fixed disc 1. The inner end of the screw 8 is fixedly connected to the outer surface of the arc-shaped clamping plate 12, and the arc-shaped clamping plate 12 is coaxially arranged with the center hole 11.

[0035] In this embodiment, the arc-shaped clamping plate can be moved back and forth along the radial direction of the fixed disc by rotating the nut pair, thereby achieving fixation with different types of vehicle hubs.

[0042] Example 6

[0043] like Figure 1 , 2 As shown, a bubble level 6 is provided on the outer surface of the ruler 3. The bubble level 6 can be used to assist in determining whether the ruler is vertical, thereby making the measurement result more accurate.

[0044] When the present invention is used, the screw can be driven to synchronously extend and retract the arc clamping plate by rotating the second bevel gear, so that the arc clamping plate is clamped and fixed outside the several fastening bolts (or several fastening nuts) of the wheel hub. After being fixed to the wheel hub, the ruler is pulled up vertically, and the height of the suspension is measured by the indicator rod. Through the above arrangement, the operation process of connecting the measuring tool with the vehicle wheel hub can be greatly simplified, the convenience is improved, and it can be applied to various types of wheel hubs, which can effectively improve the measurement efficiency.
