Wherein, support 1, attachment flange 101, Ratcheting one-way clutch 2, ratchet outer ring 201, ratchet inner ring 202, ratchet 203, band-type brake 3, anchor ear 301, brake plate 302, control end 303, pull back spring 304, retaining 305, noose 306, first drag-line 307, rotating shaft 4, link gear 5, helical coil springs 501, pulley 503, second drag-line 506, pulley guardrail 507.

The specific embodiment

Referring to Fig. 1-Fig. 3, a kind of mechanical type constant speed cruise device for automobile, comprise support 1, adopt Ratcheting one-way clutch 2 Speed control mechanism, adopt lockable mechanism, the rotating shaft 4 of band-type brake 3 and be fixed on the link gear 5 in the rotating shaft 4.Ratcheting one-way clutch 2 as Speed control mechanism is arranged on the support 1 through rotating shaft 4 with the direction that stops car acceleration pedal return.

Ratcheting one-way clutch 2 comprises ratchet outer ring 201, ratchet inner ring 202 and is arranged on the ratchet 203 on ratchet inner ring 202 excircles.201 have a rotation direction and a stop direction with the ratchet inner ring 202 sour jujube groove that 201 inner peripherys evenly are provided with in the ratchet outer ring with the effect of ratchet 203 in the ratchet outer ring, in rotation direction, and the rotation of can skidding of ratchet outer ring 201 and ratchet inner ring 202; In the stop direction, there is being stop under ratchet 203 and the effect of sour jujube groove ratchet outer ring 201 with ratchet inner ring 202.

Said lockable mechanism is a band-type brake 3, comprises that an anchor ear 301, is arranged on brake plate 302 on said anchor ear 301 inwalls, one first drag-line 307, is used for the pull back spring 304 that the noose 306 and of first drag-line 307 unclamps said anchor ear 301.One end of anchor ear 301 is riveted on the attachment flange 101 on the support 1, and the other end is provided with a control end 303, and control end is provided with a circular hole.On attachment flange 101, be provided with a screw, said noose 306 threaded one ends are connected in this screw and through a jam nut and lock.Said first drag-line 307 passes circular hole on said noose 306 and the control end 303 and fixing through a retaining 305.The other end of said first drag-line 307 connects on the automobile brake pedal (figure is last not to be shown).

Link gear 5 is made up of helical coil springs 501, pulley 503, second drag-line 506 and pulley guardrail 507.The pulley 503 of link gear 5 is fixedly connected in the said rotating shaft 4, is positioned at a side of said Ratcheting one-way clutch 2.The outer end of helical coil springs 501 is fixed on the base plate of support 1, and the inner of helical coil springs 501 is fixed on said pulley 503 1 side round platform side faces; Helical coil springs 501 is so that spring force can drive the ratchet inner ring 202 of Ratcheting one-way clutch 2 to the stop direction.Second drag-line, 506 1 ends of link gear 5 are fixed on the coiling channel bottom of pulley 503, and its other end is connected on the car acceleration pedal (figure is last not to be shown).Pulley guardrail 507 is fixed on a said side and its circumference outer end of stating pulley 503 and strides across said pulley 503, and second drag-line that is wound on the pulley 503 is protected, and prevents that second drag-line from deviating from.

Cruising device is under normal condition, and band-type brake 3 meshes with the ratchet outer ring 201 of Ratcheting one-way clutch 2 under the returning place force effect of automobile brake pedal through first drag-line 307.When adding the person of sailing and step on the car acceleration pedal, through second drag-line 506, drive pulley 503 and rotate and drive ratchet inner rings 202 and rotate to rotation direction through rotating shaft 4, rotating shaft 4 drives helical coil springs 501 works simultaneously and holds power and tighten.At this moment; Unclamp the car acceleration pedal like chaufeur, because the ratchet outer ring 201 of Ratcheting one-way clutch 2 can not be rotated by band-type brake 3 lockings; And because the ratchet inner ring 202 of Ratcheting one-way clutch 2 can not rotate by the stop direction; Therefore, the car acceleration pedal is clamped at original position through second drag-line 506, thereby has realized cruise.

And when vehicle need slow down, chaufeur was trampled automobile brake pedal and is slowed down.Because band-type brake 3 is through ratchet outer ring 201 engagements of the returning place force and the Ratcheting one-way clutch 2 of automobile brake pedal; After chaufeur is trampled automobile brake pedal; Band-type brake 3 is thrown off with the ratchet outer ring 201 of Ratcheting one-way clutch 2 under the effect of pull back spring 304; Removed the stop of the 201 pairs of ratchet inner rings 202 in ratchet outer ring of Ratcheting one-way clutch 2, return under the returning place force effect of car acceleration pedal is realized the releasing of cruise.

In the other embodiment of the utility model, it can also be provided with a master cock (figure is last not to be shown) on the car floor, and the point of connection of this master cock and first drag-line 307 is arranged between automobile brake pedal and the control end 303.Under this embodiment situation, only adopt automobile brake pedal not strain first drag-line 307, and have only when master cock is arranged on the open position, just strain first drag-line 307, make band-type brake 3 hold ratchet outer ring 201 tightly.At this moment, chaufeur is trampled automobile brake pedal, still makes first drag-line 307 loose, thereby realizes the emergency unchaining of cruise; And when master cock during at off position, first drag-line 307 is in relaxed state all the time, and band-type brake 3 ratchet outer rings 201 are thrown off, and has removed the cruise function fully.

For manually keeping off a car, first drag-line 307 can also have a shunt to be connected on the car clutch pedal (figure does not show), and cruise is removed when the plus-minus retaining.

Specific embodiment is in order more to be expressly understood the utility model; Not as a kind of restriction to the utility model right; Under the prerequisite that does not break away from the utility model aim, various variations can be arranged, as; Said link gear can convert the mechanism that rotating shaft 4 is rotated to any swing with the car acceleration pedal, as quadrant gear be arranged on the gear mesh in the rotating shaft 4; Or be arranged in the rotating shaft 4 and with the tooth bar gears in mesh etc. through said tooth bar of second drag-line 506 pulling and through rack drives; Said lockable mechanism also can be by mechanism's replacement of the ratchet outer ring 201 of any selectively latch ratchet formula free-wheel clutch 2; The also available torsion spring replacement of said helical coil springs 501 etc.; All these will be included within the scope of this claim the conspicuous modification of said those skilled in the art.
