Abstract

The invention discloses a simulation braking bench for an automobile disc brake, which belongs to the technical field of vehicle testing. A frequency converter is connected with a frequency conversion motor, the frequency conversion motor is connected with a torque and speed sensor through an elastic pin coupling, two spindles are fixed on a middle rack through four bearing blocks, the spindles and the torque and speed sensor, as well as the two spindles are connected with each other through elastic pin couplings, flywheels are arranged on the spindles, a slipping toothed electromagnetic clutch is arranged between each flywheel and the spindle, a brake system which is a real automobile brake system is fixed on a right rack through a support and connected with the spindles through couplings, an air convection device is arranged close to a brake disc, an eddy current vibration measuring sensor is installed on a pair of brake calipers, a thermal imager and a noise meter are placed close to the pair of brake calipers, and a positive pressure sensor is embedded in a brake shoe in advance. The simulation braking bench can truly simulate the work of the brake system to enable the whole simulation process to be more close to the real situation with reliable detection data.

Description

Technical field [0001] The invention relates to an automobile disc brake simulation brake test bench, which belongs to the technical field of vehicle testing. Background technique [0002] The brake is an important part of the vehicle and a vital safety device. The quality and performance of the brake affect the driving safety. With the increasing density of traffic flow, the braking performance of vehicles has attracted widespread attention from traffic control departments and manufacturers, and higher requirements have been put forward for driving safety. Therefore, the device for testing brake performance and quality, the brake test bench, plays an irreplaceable role in testing brake performance and quality. [0003] There are three main methods for testing the performance and quality of brakes: friction testing machine test, actual vehicle test, and inertia bench testing machine test. Existing tribological studies mostly use pin-disc friction testing machines to simulate disc...
