Problems solved by technology
The caliper cover is fixed on the front and rear forks or the vehicle frame in a threaded manner. The friction component is coupled to the caliper cover and forms a disc receiving groove. At least one friction component can move relative to the caliper cover. At least one piston is movably coupled to the caliper housing, and in a preferred embodiment, each piston is movably coupled to the caliper housing; the space between the caliper housing and the piston is filled with brake oil, thereby sealing the brake oil It is necessary to prevent oil leakage. In addition, the machining and manufacturing tolerances of the caliper cover and the piston must be precise to avoid oil leakage after assembly. Therefore, the processing and manufacturing costs are relatively increased; moreover, the existing oil pressure There are many caliper components, which relatively increase the assembly man-hours and manufacturing costs
In addition, due to the arrangement of the piston and other components, the volume and thickness of the overall caliper will increase, which will easily lead to collisions during riding, thus damaging the hydraulic caliper or causing the risk of functional impairment

Description
technical field [0001] The invention relates to a driving device, in particular to a hydraulic caliper driving device with small volume, simple structure, low manufacturing cost and no piston. Background technique [0002] Please refer to US Patent No. 6491144 for the existing hydraulic caliper driving device, which includes a caliper cover, a pair of friction assemblies, several pistons and a brake operating mechanism. The caliper cover is fixed on the front and rear forks or the vehicle frame in a threaded manner. The friction component is coupled to the caliper cover and forms a disc receiving groove. At least one friction component can move relative to the caliper cover. At least one piston is movably coupled to the caliper housing, and in a preferred embodiment, each piston is movably coupled to the caliper housing; the space between the caliper housing and the piston is filled with brake oil, thereby sealing the brake oil It is necessary to prevent oil leakage. In add...
