Description

Novel brake mechanism with parking function and adjustable span

Technical Field

The utility model relates to a brake equipment of motorcycle, electric motor car, especially a novel brake mechanism of taking parking and adjustable span.

Background

The brake system of the motorcycle and the electric vehicle mostly adopts a hydraulic brake mode to implement the brake. The principle of hydraulic braking is that a brake handle is manually pressed, the brake handle extrudes a piston in an upper pump shell, so that hydraulic oil in an upper pump pushes the piston on a brake caliper after passing through an oil way, and brake pads in a brake disc realize braking.

The traditional brake handle is generally provided with a parking device which enables the brake handle to have a parking function, and the parking bump is matched with the locking block by pulling the rocker arm, so that the brake handle keeps extruding the piston of the upper pump shell, the wheel is locked, and the parking purpose is achieved. The existing brake handle is designed in a single gear, the brake force can not be adjusted during parking, the gradient is slow, or the brake is kept in a tight state for a long time during parking for a long time, the brake is easily damaged, and when the gradient is steep, the defect of insufficient brake force exists, so that the parking safety is poor.

Meanwhile, the span of the brake handle is fixed, but the sizes of the palms of different drivers are inconsistent, for example, the palm of a female driver is obviously smaller than that of a male driver. Therefore, for a driver with a small palm, the brake handle is difficult to hold, the comfort and the convenience are difficult to meet, and when an emergency occurs, the brake handle cannot be timely shifted to implement braking, so that great potential safety hazards exist.
