Technical Field

The invention relates to a parking device, in particular to an oil pressure disc brake parking device.

Background

The hydraulic disc brake is a necessary component of the vehicles, and the conventional hydraulic disc brake has the problems of poor stability, convenience and use effect because the hydraulic disc brake is only fixed in clamping point for parking, and the disc cannot effectively park after the disc and the friction plate become larger in abrasion gap after the parking structure is difficult to ride for a period of time due to the fact that the hydraulic disc brake is only fixed in clamping point for parking.

As shown in fig. 1-2, the conventional hydraulic disc brake is prone to the following drawbacks due to design structure and manufacturing:

1. at present, the existing tricycle uses a one-to-two oil disc, the traditional oil disc brake parking structure is single-point parking, a handle is required to be pressed down to a braking position to keep still during parking, and a buckle is stirred to buckle the handle; therefore, the parking effect is achieved, the handle is required to be pressed down and the buckle is released when the parking is stopped, and the handle can be ridden after being reset; when the parking device works, the grip distance of the handle is changed due to the back and forth movement of the upper pump handle, so that the parking failure caused by the stroke change during parking can be caused;

2. the brake oil in the oil pressure system is lost due to long-time use, so that the single-point parking function failure is influenced;

3. the wearing of the leather sheet can lead to the reduced hand feeling of the brake handle and the shortened holding distance in the use process, and the original parking mode can not fix the handle at the position of the brake to lead the leather sheet to be incapable of clamping the disc and the parking is invalid

4. Parking force cannot be controlled, and only one-gear parking is achieved

5. When the single-point parking work is performed, the parking function structure is short in service life and low in safety coefficient due to the fact that the single-point is subjected to force parking and is easy to wear;

6. when the single-point parking is operated, the brake handle is pressed down with great force, so that the parking buckle can clamp the handle and further parking is realized;

7. when parking, the vehicle needs to be parked stably, and parking can only be performed at a single contact point, so that the operation is complicated, the parking effect is not ideal, and riding personnel are inconvenient.
