Abstract
The utility model discloses a hand braking mechanism for an automobile. A hand braking cable installation plate is fixed at the tail end of a push rod. The cable installation plate and a push rod are hinged with a toothed plate with a ratchet. The end part of a cable is fixed at the side edge of the cable installation plate through a cable fastening nut. The cable installation plate is provided with two arc surfaces and both the arc surfaces are positioned at the side of the extension end of the cable. By adopting the hand braking mechanism for the automobile, regular regulation of a hand braking operation and control mechanism is avoided, an accident is furthest avoided, the safety of an automobile user is protected, and the structure is simple, so as to be easy to implement and be suitable for various types of automobiles. The cost is not increased. The automobile maintenance cost is saved for the user.
Description
Technical field
The utility model relates to a kind of automobile parking braking field, and specifically a kind of automobile does not in use need the standing car brake operating mechanism adjusted.
Background technology
The general-duty emergency brake system is made up of hand brake operation mechanism, drag-line, parking brake assembly etc. on the automobile at present.The hand brake operation mechanism in the system wherein, the tooth plate that comprises handle, button, hand braking push rod, ratchet, band ratchet, tooth plate is fixed on the body platform, ratchet is fixed on handle rear end by rotating shaft, ratchet cooperates with ratchet on the tooth plate, button and hand braking push rod are in the through hole in the middle of the handle, and hand braking push rod is terminal hinged with ratchet, and the pull back spring that push rod is resetted to the handle front end is arranged in the through hole of handle.On the tooth plate on the hand brake operation mechanism of general manned vehicle 14 teeth are arranged, the braking force that automobile acts on the wheel when designing and developing and producing hand braking pull-up 5～8 teeth of General Definition in the assembling satisfies the requirement of braking during standstill relevant criterion.The shortcoming of this structure is: automobile parking braking is in use because hand braking drag-line tensile deformation, drag friction piece normally use wearing and tearing to cause that the number of teeth of hand braking pull-up can increase behind the running car certain hour, when the number of teeth of pull-up reaches 14 teeth and drag friction piece when can also normally use, as untimely adjustment, thereby the danger that just occurs inefficacy in the slope easily causes having an accident; For different automobile types, because the difference of hand brake operation mechanism ambient environment, hand braking mechanism is regulated also difference of complexity simultaneously.
The utility model content
The technical problems to be solved in the utility model is to realize that a kind of emergency brake system do not do still normal Parking under the prerequisite of any adjustment in long-time use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automobile hand brake mechanism, hand braking drag-line adapter plate is fixed in the push rod end, the tooth plate of described drag-line adapter plate and push rod and band ratchet is hinged, stay cable end is fixed in drag-line adapter plate side by the drag-line clamp nut, has two cambered surfaces and two cambered surfaces all to be positioned at drag-line elongated end one side on the described drag-line adapter plate.
First cambered surface of described drag-line adapter plate arrives the distance of drag-line adapter plate center of rotation less than second cambered surface to the distance of drag-line adapter plate center of rotation.
Described first cambered surface is between the drag-line fixed end and second cambered surface.
The radius of described first cambered surface is greater than the radius of second cambered surface.
Advantage of the present utility model has been to exempt regular hand brake operation mechanism adjustment, vehicle user's the safety of having avoided protecting of accident to the full extent, and also simple in structure; realize easily; be suitable for multiple vehicle, do not increase cost, and saved the vehicle maintenance and repair cost for the user.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification sheets and the mark among the figure are made brief description:
Fig. 1 is the hand brake operation mechanism scheme drawing;
Fig. 2 is a hand brake operation mechanism partial schematic diagram shown in Figure 1;
Fig. 3 is a hand braking drag-line adapter plate scheme drawing shown in Fig. 1,2;
Mark among the above-mentioned figure is: 1, push rod; 2, drag-line adapter plate; 3, the tooth plate of band ratchet; 4, drag-line; 5, drag-line clamp nut; 6, first cambered surface; 7, second cambered surface.
The specific embodiment
As Fig. 1, hand brake operation mechanism shown in 2 and partial schematic diagram thereof are as can be known, the structure of this automobile hand brake mechanism is identical with hand braking structural entity commonly used, drag-line adapter plate 2 is fixed in push rod 1 end by two fixed orifices, described drag-line adapter plate 2 and push rod 1 are hinged with the tooth plate 3 of band ratchet, pull-up push-and-pull 1 can drive tooth plate 3 rotations of drag-line adapter plate 2 with respect to the band ratchet, drag-line adapter plate 2 sides are fixed in by drag-line clamp nut 5 in drag-line 4 ends, this hand braking mechanism and the difference of other hand braking mechanism are the structure of drag-line adapter plate 2, general drag-line adapter plate 2 has only a camber line face, when hand braking pull-up, change drag-line 4 length by the camber line face, this moment, drag-line was stretched, drag-line adapter plate 2 on this hand braking mechanism is by former and later two camber line faces 6,7 form, and two cambered surfaces 6,7 all are positioned at drag-line 4 elongated ends one side, just when pull-up is hand braking, when rotating with drag-line adapter plate 2, drag-line 4 reaches the effect of stretched length successively through first cambered surface 6 and second cambered surface 7, when eight teeth of hand braking mechanism pull-up are following, first cambered surface 6 of drag-line adapter plate 2 works, and this moment is as hand braking mechanism commonly used; When vehicle ' after a period of time, since must lose in the parking system cause eight teeth of pull-up with interior can not Parking, second cambered surface 7 of drag-line adapter plate 2 begins to work at this moment, increases stretched length for 4 one downward pressure of drag-line and promotes the Parking effect with this.
Hand braking drag-line adapter plate scheme drawing as shown in Figure 3 as can be known, first cambered surface 6 is between drag-line 4 fixed ends and second cambered surface 7; First cambered surface 6 of drag-line adapter plate 2 arrives the distance of drag-line adapter plate 2 center of rotation less than second cambered surface 7 to the distance of drag-line adapter plate 2 center of rotation.That is to say that the length of its stretching is bigger when drag-line 4 provides tensile force by second cambered surface 7, the radius of first cambered surface 6 can be greater than the radius of second cambered surface 7 simultaneously.
