Abstract
A static rigidity testing device for a pull rod body of a parking brake assembly is characterized by comprising a table, a cylinder and an automobile brake hub. An assembly base, a cylinder base and a hub base are arranged on the table, the cylinder is mounted on the cylinder base, the automobile brake hub is mounted on the hub base, and an air-source triple component and a reversing valve are arranged on an air way of the cylinder. When in a testing state, the automatic brake hub is connected with a to-be-tested parking brake assembly through a brake line, and the cylinder is connected with the to-be-tested pull rod body mounted on the assembly base through a steel cable. The static rigidity testing device is simple in structure, low in manufacturing cost, reliable in performance and applicable to popularization for medium and small sized automobile part machining enterprises.
Description
Technical field
The present invention relates to a kind of static rigidity proving installation, especially a kind of bar body to the automobile parking braking assembly carries out the device of static rigidity test.
Background technology
The parking braking assembly is by bar body and be contained in the parts such as its inner gear, ratchet, spring and form.After the machining of parking braking assembly, be the performance that ensures safety, must test the quality of assembly that wherein, it is an important indicator estimating the assembly quality that the static rigidity of bar body detects.According to the requirement of parking braking assembly technical conditions, draw, press down the stressed static rigidity test of both direction on must carrying out bar body, with the reliability of the material selection of checking bar body and job operation.Traditional method of testing is to adopt comprehensive vehicle performance detection machine to detect, and this equipment price is expensive, is unsuitable for small and medium-sized car spare and accessory parts processing enterprise and uses.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of parking braking assembly bar body static rigidity proving installation, and it is simple in structure, and cost is low, and dependable performance is suitable for small and medium-sized car spare and accessory parts processing enterprises.
The present invention adopts following technical scheme: comprise stand, cylinder and automotive brake hub, described stand is provided with assembly seat, cylinder block and hub seat, cylinder is installed on the cylinder block, automotive brake hub is installed on the hub seat, the gas circuit of described cylinder is provided with source of the gas three linked piece and reversal valve, during test mode, automotive brake hub is connected with tested parking braking assembly by brake cable, and cylinder is connected with the tested bar body that is installed on the assembly seat by cable wire.
This principle of device is: according to Test Condition Requirements, the assembly structure of parking braking assembly in the simulated automotive on stand, cylinder is connected with the tested bar body that is installed on the assembly seat by cable wire, adopt the mode of the pneumatic application of force (on draw or press down), reduction valve knob adjustable pressure by the source of the gas three linked piece, different cylinder pulling force (namely setting different bar body stresses) can be set, gather respectively the deflection data of bar body, realize thus the test purpose of bar body static rigidity.Concrete grammar is, bar body is arranged on the assembly seat on the stand by the automobile installment state, is connected with automotive brake hub by brake cable, and adjusts the preparation pulling force.According to the requirement of test program, adopt respectively and draw or press down two states, by cable wire bar body is connected with cylinder, adjustable pressure can arrange different cylinder pulling force, measures respectively the deflection data of bar body with height gauge.
