Vertical hanging ABS sensor detection drive device

Abstract

The invention provides a vertical suspended detection drive device for an ABS sensor. The device is characterized in that a drive motor is vertically arranged; a horizontal mounting plate is fixed on a speed reducer of the drive motor; a driving disc is fixedly connected to a horizontal output shaft of the speed reducer, and is connected with a wheel hub driving disc through a connecting rod; the horizontal mounting plate is sleeved on a hoisting rod through two hanger brackets; the hoisting rod is sleeved on a guiding axle through a connecting block; the guiding axle is sleeved in an end sleeve of a suspension arm; the suspension arm is arranged on a rail of an upper beam through a roller wheel; and a balancer is arranged between the suspension arm and the guiding axle. The vertical suspended detection drive device has the advantages of simple structure, stable motion, accurate control and convenient installation and maintenance, and can effectively carry out online detection on the assembly quality of the ABS sensor.

Description

technical field [0001] The invention relates to testing equipment for key parts of automobiles, more specifically, a device for on-line detection of automobile ABS sensors, so as to accurately detect the output signal of the ABS sensor at a certain speed and judge its overall assembly quality. Background technique [0002] The ABS anti-lock braking system is to prevent the wheels from locking during emergency braking, improve the braking performance of the vehicle and maintain the steering ability. The performance of ABS directly affects the stability of the braking system, which is related to the safety of the vehicle. Performance in terms of power, fuel economy and driving comfort. Improving the braking performance of ABS can not only improve the performance of the transmission system and reduce the fuel consumption of vehicles, but also has great significance in suppressing the traffic safety problems caused by the increase of vehicle speed in recent years.

Problems solved by technology

Its disadvantages are twofold. One is that the rotation speed of this manual rotating hub is extremely unstable, and the repeatability of the measured results is not high; If the detected ABS signal is higher than the threshold value, it is judged to be qualified, but the specific measurement value and range cannot be displayed, which is very unintuitive

Obviously, this rough ABS detection method has low reliability and cannot meet the needs of production.

[0005] At present, in the existing ABS sensor detection drive test device, the structural forms include bench horizontal drive and suspension vertical drive. However, the disadvantage of bench horizontal drive is that the test piece must stop running during the test, which affects online testing. The efficiency is high, and it takes a long time to adjust the centering when changing the variety; the suspension vertical drive is very inconvenient for the user to control because the reducer is a concentric shaft and the size is long
