Abstract

The utility model provides a hand brake device combined with a handlebar of a handlebar type vehicle. The hand brake device comprises a handlebar bracket, an oil sac, a needle cylinder and a sac cover, wherein the handlebar bracket is provided with an accommodating chamber for accommodating the oil sac and a wrapping and clamping part arranged at the rear side of the accommodating chamber; the needle cylinder is accommodated in the oil sac through the combination of the oil sac and the sac cover; the oil sac comprises an oil tank, a small bundling ring and a large bundling ring; the needle cylinder comprises a clamp ring, a hollow oil chamber and an oil outlet; and the sac cover comprises a central through hole for allowing the needle cylinder to penetrate through, a ring thread combined with the oil sac and an oil filling port. By means of the shape, the structure and the combination of the shape and the structure, an oil pressure hand brake device of the handlebar type vehicle, which simultaneously has the functions of beautifying the appearance, reducing the wide resistance and ensuring that a brake oil path is smooth, is realized.

Description

A kind of hand brake device

Technical field

The present invention provides a kind of hand brake device, refers to a kind of oil pressure hand brake device that is suitable for the wushu car especially.

Background technology

The wushu driver who commonly uses stops and has lubricating cup and expose, and problem such as oil circuit obstruction, has shortcoming because of its lubricating cup is exposed on attractive in appearance outward, can't reach and see outside the streamline, can produce unnecessary windage.And since handle bracket be with processing modes such as casting, forgings one-body molded after, again through machined into boring, mill pin and go out accommodation chamber, its accommodation chamber periphery is after processing; Material contacts with hydraulic oil for a long time, corroded by hydraulic oil and produces chip, makes the accommodation chamber endoporus periphery material of its handle bracket produce qualitative change; Cause the handle bracket integral structure to wreck at last; Or, the sensitivity of brake is reduced or brake failure because of its debris oil circuit, make the rider that the hidden danger on the safety take place.

In view of this; The inventor knows very well its manufacturing and uses has this disappearance, and revises improvement, simultaneously in line with the spiritual theory of innovating, asking; By the experience and clever thought, the test in many ways of professional domain for many years, design a kind of oil pressure hand brake device of handgrip car finally.

Summary of the invention

For solving above-mentioned technological deficiency, main purpose of the present invention is to provide a kind of oil pressure hand brake device of wushu car.

The present invention realizes as follows:

A kind of hand brake device combines with the handgrip of wushu car, comprises handle bracket, oil sac and syringe, and operculum, and wherein: this handle bracket is provided with the holder that the accommodation chamber that holds oil sac and rear side thereof have; This oil sac combines operculum that syringe is contained in the body, comprises that oil groove, little beam ring and big beam ring and this syringe comprise snap ring, hollow grease chamber and oil outlet, and this operculum, comprise supplying central bore that syringe wears and combining ring grain with oil sac, and pouring orifice.

In embodiments of the present invention, this hand brake device comprises that further said grease chamber is provided with returning spring, piston and packing ring.

In embodiments of the present invention, said oil outlet is communicated with the oil groove of oil sac.

In embodiments of the present invention, said holder is fixed as one handgrip through the female mating type bolt of a pair of public affairs, and the operculum inclusion is clamped.

In embodiments of the present invention, said little beam ring, big beam ring support within accommodation chamber before and after dividing.

In embodiments of the present invention, the collar extension that is provided with of said ring grain and said oil groove is twisted and is closed.

The beneficial effect of the invention is:

This brake gear can avoid protecting that hole peripheral is not corroded by hydraulic oil in the handle bracket accommodation chamber, and lets the lubricating cup that exposes on the handle bracket be hidden in the handle bracket, and reaching has the outward appearance of beautifying to have the attenuating windage concurrently, and makes the unimpeded function of brake fluid line.

Description of drawings

Fig. 1 is the three-dimensional exploded view of preferred embodiment of the present invention.

Fig. 2 is an assembling stereogram of the present invention.

Fig. 3 is the generalized section after Fig. 1 assembles.

The specific embodiment

Relevant a kind of hand brake device of the present invention is applicable to that the parking brake of wushu car is constructed, and technological means of being taked and the purpose of being reached cooperate brief description of drawingsfig following with most preferred embodiment now:

See also Fig. 1 and combine and consult Fig. 2, shown in Figure 3, a kind of hand brake device combines with the handgrip 10 of wushu car, comprises handle bracket 20, oil sac 30 and syringe 40, and operculum 50, wherein:

This handle bracket 20 is provided with the accommodation chamber 21 that holds oil sac 30; Said accommodation chamber 21 rear sides have the holder 211 that clamping operculum 50 can not come off naturally; This holder 211 is in integral cast handle 10, operculum 50 inclusions to be clamped unlikely coming off through the female mating type bolt 22 of a pair of public affairs;

This oil sac 30 combines operculums 50 that syringe 40 is contained in the body, comprises by central bore forming the tuftlet ring 32 that oil groove 31 and front end are provided with, and the big beam ring 33 that is provided with of rear end, and said

tuftlet ring

32,33 fens front and back of big beam ring support within accommodation chamber 21;

This syringe 40 comprises that snap ring 41, internal diameter that front end is provided with are provided with the oil outlet 43 that hollow grease chamber 42 and external diameter middle section are provided with; Said grease chamber 42 is provided with returning spring, piston and packing ring (figure does not show); Said oil outlet 43 is communicated with the oil groove 31 of oil sac; Can make hydraulic oil in the

grease chamber

42 and 31 in oil groove flow, and

This operculum 50 comprises supplying central bore 51 that syringe 40 wears and combining ring grain 52 with oil sac 30, and the pouring orifice 53 that is provided with of rear end, and oil sac 30 centers are provided with open-work and form oil groove 31, collar extension 311 stubborn the closing that said ring grain 52 and said oil groove 31 are provided with.

In sum, a kind of hand brake device of the present invention can improve that traditional handle bracket lubricating cup exposes and problem such as oil circuit obstruction; It is to utilize oil sac 30 to substitute lubricating cup; This oil sac 30 coats syringe 40, protects that hole peripherals are not corroded by hydraulic oil in this handle bracket accommodation chamber 21, and lets the lubricating cup that exposes on this handle bracket 20 be hidden in the handle bracket; Reach and beautify outward appearance and have the attenuating windage concurrently, make the unimpeded function of brake fluid line.

Shape, structure and the combination thereof of comprehensive above narration; Be all a preferred embodiment of the present invention's creation; Be not the patent right scope that is used to limit the invention, the equalization replacement that all interest fields of applying for a patent with reference to the present invention creation are made and revising is all the present invention and creates institute and contain.
