Summary of the invention
The purpose of this invention is to provide a kind of operating control, utilize simply assembling, guarantee when using parking brake, can reduce noise well.
Utilization a kind of operating control according to the present invention just can be realized the object of the invention, wherein the pallet spring is designed to compression spring and combines with pallet at the end away from parts of tooth, fixed detents is designed to an independent double lever, only in executing state, connecting rod mechanism make blocked pallet against the pretension of pallet spring with the parts of tooth jump out of mesh.
Operating control according to the invention has reduced the starting power that acts on the fixed detents, and caused noise can be regarded as the function of compression spring elastic force when using brake activation lever, is also correspondingly reduced.The noise engagement of engaging tooth also is reduced, using under the common parking brake situation, the undue sound that mechanism produced has represented to occur the engagement of inharmonic engagement cingulum noise, uses cheap element in present device, use this mode, do not need independent noise insulation.Can obtain simultaneously to be applied to the starting power that has predetermined sizes values on the preceding end button of push rod, for security reason, this overcomes possibly little, thereby operating control according to the invention preferentially is used for manual parking brake.
The structure that meets operating control of the present invention can obtain following effect, when inseparable fixed detents is rotated, break away from combine with connecting rod mechanism and mean that connecting rod mechanism can not move, thereby the perceptible motion of vision takes place to vibrate or occur in the button that can avoid being arranged on the end face.Give the quiet mechanical characteristics of a kind of operating control of driver on the whole.
Utilize the thinking of compression spring as the pallet spring, thereby realized combining of this compression spring and fixed detents with a kind of reliable and worthwhile mode of cost-effectiveness, can utilize the device that simply makes compression spring abut against an end of shell to finish installation to operating control, described shell is used in abutting connection with compression spring.By a stops or a stops that is used for fixing pallet that is used for compression spring, can the limit compression relaxing of spring, thereby on the one hand, can between the abut of connecting rod mechanism end and fixed detents, keep determined minor increment, on the other hand, at connecting rod mechanism during starts, described minor increment can be used as the idle travel of connecting rod mechanism.
Face on the quarter butt of parts of tooth in fixed detents, a meshing flake is set, this meshing flake might not vertically be provided with on lever, also can be configured to and parts of tooth ingear lateral projection, thereby when meshing flake meshes, brake activation lever is fixed on its use location, has an angle between described use location and the release position.
Be preferably on the stock of fixed detents away from parts of tooth, an abut is set, only when being manipulated to a certain degree, the end of connecting rod mechanism is low against this abut, in the case, when not handling, connecting rod mechanism end and this abut disengage, thereby only under the elastic force effect of pallet spring, fixed detents and parts of tooth engagement are by this device, parking brake can be unclamped to a certain degree, then by finishing starting, guarantee that it can be once more and the parts of tooth engagement, and do not require that hand brake returns its initial position fully and reuses hand brake.Between connecting rod mechanism and fixed detents, do not have obedient body to connect, thereby two relevant apparatus can be changed independently of one another in the parking brake, have simplified installation.
Abut is arranged on the fixed detents stock on the side away from parts of tooth, thereby when control link mechanism, the elastic force of pallet spring and the elastic force of push rod spring point to same direction basically, therefore when design, also will consider the direction of the elastic force that applies.
In connecting rod mechanism adjacent stop point zone, on connecting rod mechanism, be equipped with a kind of guides along brake activation lever, thereby when pressing button, the percussion movement of connecting rod mechanism is directed on the direction of fixed detents, connecting rod mechanism is guided into the abut that is arranged on the fixed detents.Guides preferably is made up of the groove that is arranged on the connecting rod mechanism end, and a pin combines with this groove, preferably groove is integrally formed on the connecting rod mechanism, and pin is fixed on the brake activation lever.The longitudinal axis of this groove overlaps with the crash direction of connecting rod mechanism basically, and substantially parallel with the spindle axis of pallet spring, and these two axis are lateral drift each other also.The pallet spring preferably combines with the end of fixed detents bar, thereby during meshing with tooth, rotates in order to make fixed detents, need big relatively spring travel, thereby gearing noise is not noticeable.
Can worthwhile ground of cost efficiency production fixed detents, thereby it is produced as the sheet metal rolled-up stock, and another kind of method is to utilize injection-moulded plastic production fixed detents, thereby when the starting drg slides fixed detents on parts of tooth, further reduced noise.
Except being provided for using and unclamp the element of connecting device, operating control also is useful on the homing device of connecting device, this homing device resets brake pull cable, if for example the latter is taken place sagging or owing to other reason overtime, cause the parking brake can not be locked, must make brake pull cable return initial condition so that fixing parking brake in the latched position of a plurality of fixed detents.In order to realize this purpose, homing device preferably comprises a cable pulley, pass through spring load, this cable pulley can play a role on the service orientation of brake pull cable, can be connected with brake activation lever with the driving pallet that is designed to the tilting bar form by the parts of tooth that circumferencial direction distributes, can put upside down the courses of action of carrying out the hand brake lever, utilize spring load, when parking brake was released, this cable pulley guaranteed that brake pull cable is in tension.
The operating control that is used for parking brake according to the invention can be applied to manual parking brake and foot-propelled parking brake.
With push rod and fixed detents is that two disjunct each other element design are opposite, and another kind of scheme is that these two elements are structurally connected so that simplify assembling.In order to realize this purpose, push rod and fixed detents can be designed to an integral member.Although be unit design, according to the present invention, fixed detents can be designed to a kind of non-(form-fitting) next to the shin connection mode with respect to the displacement that is used for jaw closing movement of connecting rod mechanism, because the use of brake activation lever, pallet is on parts of tooth when mobile, during pallet rotated, connecting rod mechanism was not followed the pallet motion.In the case, only need to overcome and the relevant pallet spring force of the small noise of generation.Yet two elements adopt a kind of mode mode next to the shin to link to each other at least, therefore, when connecting rod mechanism moves against the pallet spring, drive fixed detents and move together, utilize this mode, and blocking is unclamped.
By groove on one of two elements and the pin that is arranged on another element, connecting rod mechanism and fixed detents are connected with each other, this pin combines with this mode with this groove, and promptly under the situation that does not make connecting rod mechanism movement, fixed detents can be rotated against the pretension of pallet spring.In this connected, groove can have and the cooresponding curved surface of the bending spring of pin.

The specific embodiment of the present invention
Fig. 1 has shown the part of hand brake 1, and this hand brake 1 has and is set together with car body so that co-rotational bridge support 2, and by binding site 3, brake activation lever 4 is hinged with this bridge support 2.This bridge support 2 has the tooth 5 of the circumferencial direction distribution that is arranged on the circular arc portion, and the center of circle of this circular arc portion and binding site 3 are same point.
Be hinged on the brake activation lever 4 by binding site 6, one pallets 7, this pallet 7 has a quarter butt 7a and the stock 7b away from tooth 5 in the face of tooth 5.Form a meshing flake 8 on the front side of quarter butt 7a, when using hand brake 1, for the fixing position of hand brake 1, this meshing flake 8 will mesh with tooth 5.When not using hand brake 1, this meshing flake 8 leans against in the zone 9, and this zone 9 is set on the parts of tooth prolongation and is inwardly recessed with respect to engage position.
Forming 10, one compression springs 11 of a projection on to the side of supporting bracket 2 on the stock 7b of fixed detents 7 is that disc spring combines with this projection 10.Be installed in a kind of stationkeeping mode of compression spring 11 usefulness on the brake activation lever 4 and be positioned at shell shape clamper 12, compression spring 11 applies pretension to fixed detents 7 on the engagement direction.An abut 13 is being set on away from projection 10 surface on the stock 7b, described abut 13 is with respect to the profile projection of stock 7b and have semicircle outline.
Brake activation lever 4 also has the connecting rod mechanism 14 that comprises a push rod 15, substantially axially be arranged in the brake activation lever 4 with this push rod of this mode, promptly when pressing the promotion button (not shown) that is set at hand operation brake rod 4 front ends, under the effect of spring element (not shown), push rod 15 moves.The rear end of push rod 15 comprises an axially directed device 16, and this axially directed device is one to be arranged on the groove 17 of push rod 15 end regions, will sell 18 and be assemblied in the groove 17, thereby determine the axial manipulation path of push rod 15 basically.End face 19 is limited to the back of guides 16 with the border of push rod 15, when meshing flake 8 leans against in the zone 9 when fixed detents 7 is in dead position, and existence one minim gap 20 between the abut 13 of end face 19 and fixed detents 7.
Contact and make for the end face 19 of the abut 13 that stops fixed detents 7 and push rod 15 is next to the shin and always have gap 20 between the two, during control link mechanism 14, provide the idle travel of a weak point by overcoming this gap, it is to be limited by stops for the peak excursion that makes spring 11 that this gap is set.This stops can be arranged in the spring offset area or be arranged in fixed detents 7 scopes, can act on quarter butt 7a by stagnant zone 9 equally, the peak excursion of spring is limited.
Hereinafter will introduce the operating mode of parking brake according to the invention in conjunction with the different operation state in Fig. 1～3.
Extended position (set down position) from hand brake 1 shown in Figure 1, by the rising brake activation lever, directly or indirectly the brake pull cable that links to each other with brake activation lever is tightened up, thereby the brake shoe or the brake plate that link to each other with brake pull cable enter braking position, for example be resisted against on the wheel rim of motor vehicle wheel, stop wheel.The connecting device that brake pull cable is linked to each other with brake activation lever can comprise direct transmission power equipment and power assistive device, specifically, design this connecting device like this, it can automatically be resetted, in case use brake activation lever, tension force just are sent to brake pull cable.Such connecting device that automatically resets is known, will this be discussed in detail.
When using brake activation lever 4, this bar rotates around binding site 3 along direction shown in the arrow 21 and connection element is thereon moved simultaneously, and specifically, fixed detents 7, connecting rod mechanism 14 and spring 11 are with respect to bridge support 2 motions that are fixed on the car body.In the case, along with the meshing flake 8 of fixed detents 7 slips over the circular portion profile, fixed detents 7 is rotated around binding site 6.Meshing flake 8 leaves the dead position in the zone 9, along with meshing flake 8 moves along circular portion 5, spring 11 is compressed, at the end that rotates along arrow 21, the elastic potential energy of spring is very big, thereby by acting on the elastic force on the stock 7b, this spring press fit pallet 7, when in the teeth groove of meshing flake 8 between two teeth 5,, make between brake activation lever 4 and bridge support 2 and the tooth 5 thereof to have an angle with brake activation lever 4 lockings.In Fig. 2, show that spring 5 is in confined state, can see that the gap 20 between end face 19 and the abut 13 has correspondingly increased.The required spring force of locking is very little, because the power that acts on the tooth is very little, thereby the noise that is produced when at every turn meshing flake 8 being locked between two teeth of tooth 5 is attenuated, and it is disagreeable not make us sensation.Should be noted that stock 7b more helps to realize this specific character than quarter butt 7a, can make meshing flake 8 and tooth 5 engagements with moving of stock being passed to quarter butt relative to little elastic force.
In Fig. 3, by pressing the button that is arranged on end face, utilize a powerful compression spring that push rod 15 is moved backward, the end face 19 of push rod 15 is low against abut 13, thereby push rod 15 is mobile backward against the elastic force of spring 11, pallet 7 is moved around binding site 6, use this mode, the pin 18 in the groove 17 is set near the front end of groove 17.Because this frictional connection between push rod 15 and the fixed detents 7, meshing flake 8 (or leaves dead position 9 with tooth 5 jump out of meshs, if when hand brake is in the release position, press button), by using hand brake, the hand operation brake rod can resemble the prior art released.What should consider is, is semicircular in shape by making abut 13, and when push rod 15 contact abuts 13, the end face of push rod 15 always tangentially contact with abut 13, guarantees that abut 13 slips on end face 19, thereby stops inclination or clamping stagnation.If release button, push rod 15 turns back to position shown in Figure 1, because the pretension of compression spring 11, fixed detents 7 enters the halted state of bridge support 2 peripheries once more, and in the dead position 9 of releasing orientation, parts of tooth 5 and hand brake are in releasing orientation.
Above introduced the present invention with reference to exemplary embodiments, wherein, the groove 17 that is arranged on the push rod 15 can be with respect to pin 18 motions that are fixed on the brake activation lever 4.Except the counter motion that it is contemplated that, also this mode of pin 18 usefulness can be arranged on the fixed detents 7, promptly there is not connection next to the shin between two elements, only when the brake activation device, fixed detents 7 and connecting rod mechanism 14 frictional connectiones.
Below the present invention has been done very detailed description, thus after reading and having understood this specification sheets, for a person skilled in the art, various changes of the present invention and revise and will become obvious.So all are so changed and correction is also included within this invention, so they are in protection scope of the present invention.
