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...

Examples

Embodiment 1

[0031] as attached figure 1 As shown in Appendix 7:

[0032] The invention provides a braking force detection device for vehicle engineering. Its structure is provided with a platform 1, a platform 2, and a detection device 3. The platform 2 is embedded and installed with the platform 1 and is located at the front and rear ends thereof. The device 3 and the stand 1 are of an integrated structure.

[0033] The detection device 3 is provided with an intermediate plate 31, a detection control box 32, and a drum brake device 33. The intermediate plate 31 and the stand 1 are of an integrated structure, and the detection control box 32 is embedded and installed inside the intermediate plate 31. One side of the drum braking device 33 is embedded in the side end of the middle plate 31 , and the drum braking device 33 is movably matched with the detection control box 32 .

[0034] Wherein, the drum braking device 33 is provided with a drum 331, a roller shaft 332, an intermediate fra...

Embodiment 2

[0041] as attached Figure 8 to attach Figure 9 Shown:

[0042] Wherein, the hemispherical block q3 is provided with a bouncing block q31 and an expansion ball q32, the inner ring q23 is connected with the bouncing block q31 and movably matched, and the bouncing block q31 is connected to the rear end of the scraping block q1, so The expansion and contraction ball q32 is in clearance fit with the inner side of the elastic block q31. The elastic block q31 is arc-shaped and has good elasticity. The expansion and contraction ball q32 is spherical and can be changed in size. The elastic block The q31 cooperates with the expanding and contracting ball q32 to make the hemispherical block q3 elastically deform in a hemispherical state, which is convenient to assist and drive the position change of the scraping block q1.

[0043] Wherein, the expansion and contraction ball q32 is provided with a tough block w1, a weighted ball w2, and a telescopic frame w3. The frame w3 is connecte...
