Embodiment Construction

[0021] The invention provides a detection device for a drum brake, which includes a detection table and a control system. The detection table is provided with an electric cylinder, a detection part and a positioning seat for placing the drum brake. The detection part includes a tension sensor and a displacement sensor. The tension sensor passes through The pull wire is connected to the drum brake in the positioning seat, the electric cylinder drives the pull wire to pull the drum brake to reach the parking brake state and release the pull wire to restore the drum brake to the initial state, the tension sensor and the displacement sensor respectively detect the pull force of the pull wire during the driving process of the electric cylinder And stroke, tension sensor and displacement sensor are electrically connected to the control system. The tension sensor and the displacement sensor feed back the tension and stroke measured during the process of the drum brake reaching the par...

Abstract

The invention discloses a detecting device for a drum brake, and relates to the field of testing devices. The detecting device for the drum brake solves the technical problem that a detecting device of the drum brake is complex in structure and operation in the prior art. The detecting device of the drum brake comprises a detecting table and a control system. An actuator, a detecting member and a locating base for containing the drum brake are arranged on the detecting table, and the detecting member comprises a tension sensor and a displacement sensor. The tension sensor is connected with the drum brake in the locating base through a stay wire, the actuator drives the stay wire to pull the drum brake to achieve a parking brake state and releases the stay wire to enable the drum brake to reset to an original state, the tension sensor and the displacement sensor detect the tensile force and the stroke of the stay wire in the driving process of the actuator respectively, the tension sensor and the displacement sensor are electrically connected with the control system, and the control system can calculate the working starting force and the engineering displacement of the drum brake according to the feedback signals of the tension sensor and the feedback signals of the displacement sensor.

Description

【Technical field】 [0001] The invention relates to a detection device, in particular to a detection device for a drum brake. 【Background technique】 [0002] When a car with an EPB electronic parking system uses a drum brake, when the electronic parking is activated, when a certain tension is applied to the drum brake, there are technical requirements for the initial tension of the drum brake, the cable stroke and other technical parameters, so that Guarantee the braking effect of the drum brake. At present, the detection of drum brakes is mainly carried out by the special test equipment in the detection center, and the operation is complicated and requires professional and technical personnel to carry out the detection, which cannot meet the requirements of mass detection on the production line. 【Content of invention】 [0003] The technical problem solved by the invention is to provide a drum brake detection device, which can detect the braking effect of the drum brake, an...
