Problems solved by technology

[0004] At present, the main difficulty in developing low-drag or even zero-drag brake calipers is that the existing technical solutions cannot accurately measure the drag torque value generated by the friction between the brake pad on one side and the brake disc, and it is difficult to accurately measure the drag torque value of the brake caliper. Targeted optimization and improvement of the structure
Therefore, the prior art lacks a device that can accurately measure the drag torque produced by the friction between the brake pads on each side and the brake disc

Abstract

The invention discloses dragging torque detection equipment for a disc brake caliper. The equipment further comprises a driving device, transmission mechanisms, couplings, torque sensors and simulation brake discs, the two output ends of the driving device are connected with one ends of one transmission mechanism through the couplings respectively, and the other ends of the two transmission mechanisms are connected to the two simulation brake discs on the brake through the torque sensors and the couplings respectively. The two simulation brake discs on the brake are coaxially installed and do not make contact with each other. The brake is connected with the hydraulic device through an oil pipe; and the brake is mounted on the brake caliper mounting frame. The equipment can accurately measure the single-side dragging torque generated by friction between a single-side brake block of the disc brake caliper and a brake disc, and can also measure the total dragging torque generated by friction between brake blocks on the two sides and the brake disc. The equipment fills the blank in the field, and provides equipment support for design and development of low-dragging and zero-dragging brake calipers.

Description

technical field [0001] The invention relates to a device for detecting drag torque, in particular to a device for detecting drag torque of a disc brake caliper. Background technique [0002] According to CN 209745453 U known a kind of braking drag torque dynamic test device, this type of device is driven by a drive device through the transmission shaft to drive a brake disc to rotate, to simulate the operating state of the brake disc in the real vehicle state, the load cell and The force rod is fixedly connected. When the driving device drives the brake disc to rotate, the friction block of the brake caliper contacts with the brake disc to generate friction. The load cell can accurately measure the friction between the brake disc and the brake caliper friction block Force, and then obtain the drag torque value of the brake caliper through data processing. [0003] This type of equipment can quickly and accurately measure the drag torque value generated by the interaction be...
