Description
Technical field
The utility model relates to a kind of Brake for vehicle spare, specifically refers to a kind of skid control brake.
Background technique
At present, hydraulic brake has the advantages such as volume is little, lightweight, good thermal stability, becomes gradually the main flow break of motorcycle.The structure of existing hydraulic brake has generally comprised pump assembly, Brake hose, lower pump assembly and brake disc, wherein go up pump assembly and include the structures such as upper pump casing, handle, plunger and plunger return spring, lower pump assembly includes lower pump body, piston, two mechanisms such as brake shoe, its working principle is to utilize the lever drive plunger to move, make the hydraulic pressure of pump assembly raise, and the piston movement of the lower pump assembly of driving, and then promote two brake shoes clamping brake discs, realize car brakeing.Yet, the plunger return spring of upper pump assembly described in the prior art is cylindrical spring, the problem of its existence is after long-time the use, cylindrical spring easily occurs around folding, cause in time coupled columns to fill in horizontal reset, thereby cause the oil pressure in pump assembly to remain on a high position always, thereby make the brake shoe locking, have potential safety hazard.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and a kind of a kind of anti-lock hydraulic brake that can effectively prevent the brake shoe locking is provided.
for achieving the above object, the technical solution of the utility model is a kind of anti-lock hydraulic brake, include pump assembly, brake pipe, lower pump assembly and brake disc, upper pump assembly is connected by brake pipe with lower pump assembly, described upper pump assembly includes oiling pump and handle, described oiling pump comprises upper pump casing, upper pump casing is provided with lubricating cup and plunger cavity, be equipped with plunger assembly in plunger cavity, described plunger assembly comprises the plunger with the handle interlock, the plunger return spring that is arranged at intervals at front leather cup on plunger and rear leather cup and is used for plunger return, described lubricating cup and plunger cavity are provided with oilhole, described lower pump assembly includes lower pump body, support, the a pair of brake shoe that is arranged at the piston in lower pump body and links with piston, described a pair of brake shoe symmetry is installed with the both sides in brake disc, it is characterized in that: described plunger return spring is volute spring.By this setting, utilize the good advantage of flexible centering of volute spring, be used for resetting of plunger, can prevent effectively that spring is around the problem of folding, ensure the plunger parking position accuracy, thereby the problem that can effectively reduce and evade the brake shoe locking has improved the Safety performance of product.
Further arrange is compensation oilhole and the dish oil through of space before and after described oilhole includes.Because wearing and tearing in use can appear in brake shoe, by space compensation oilhole and dish oil through are set, can make after brake shoe plate abrasion, ensure that plunger can move enough strokes, and then ensure that brake shoe locks brake disc, improved the working life of product.
Be provided with dust-proof cover between the outer end that further setting is described plunger and plunger cavity.By this setting, prevent that external dust from entering in plunger cavity, affect the normal movement of plunger.
Further arranging is that described oil pipe is Brake hose.
In sum, the utlity model has anti-lock effective, the advantages such as long service life.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
