Braking force detection device for vehicle engineering

Abstract

The invention discloses a braking force detection device for vehicle engineering, which is structurally provided with a rack, a bedplate and a detection device, the bedplate and the rack are fixedly mounted in an embedded manner and are positioned at a front end and a rear end of the bedplate, the detection device and the rack are of an integrated structure, the detection device is provided with a middle plate, a detection control box and a roller braking device, and contact is generated on an outer end face of a roller through a side butting device; a connecting block facilitates displacement of a scraping block along with the magnitude of the abutting force, a limiting rail is matched with a fixing rod, the displacement limit of the abutting block is integrally controlled, elastic property of the hemispherical block facilitates further driving of the abutting block to generate position change and angle change, and the abutting block can buffer the abutting force in time after abutting against the roller; resistance to the roller in the rotating process is reduced, meanwhile, the shoveling and scraping effect on substances on the outer end face of the roller can be achieved, the rotation driving frame increases rotation driving power in the outer ring, a rotation ball rotates continuously, substances falling on the scraping block can be driven to rotate and slide off conveniently, and therefore the substances attached to the outside of the roller can be shoveled away in time.

Description

technical field [0001] The invention belongs to the field of vehicle detection, and more specifically relates to a braking force detection device for vehicle engineering. Background technique [0002] Braking performance is one of the main performances of a motor vehicle, which is directly related to the driving safety of the vehicle. Once the braking system fails, it is easy to cause traffic accidents. Therefore, people need to check whether the braking system is damaged and whether it needs to be replaced when using the vehicle. etc. The brake performance test mainly uses a bench test (roller brake test bench) to detect the braking rate, braking imbalance rate, parking brake rate, etc. [0003] Based on the above-mentioned inventor's discovery, the existing braking force detection device for vehicle engineering has the following deficiencies: [0004] Vehicle wheels are braked on the drum for detection. Since there is usually dirt on the wheel, the brake stops on the drum...

AI Technical Summary

Problems solved by technology

[0004] Vehicle wheels are braked on the drum for detection. Since there is usually dirt on the wheel, the brake stops on the drum, which can prevent dirt from adhering to the drum. The remaining substances are on the outer wall of the drum, making the surface not smooth enough. In the brake test, there is a certain friction force on the wheel, which makes the detection of the vehicle brake not accurate enough
