Description

Spring combined disk

Technical field

The present invention relates to auto parts and components technologies, more particularly, to a kind of spring combined disk on clutch.

Background technology

Currently, spring is substantially be unable to do without on the clutch of the mechanical equipments such as automobile, lathe, spring combined disk in clutch Thrust ring to spring positioning poor accuracy, easily loosen, cause its sensitivity bad, generate security risk.Spring combined disk exists It is mainly designed according to its required function in practical application.If Chinese Patent Application No. is a kind of 200710168634.8 arcs The auto parts and components of shape spring vibration reduction fly wheel assembly, it has flywheel main body, is especially equipped with arc in the side of flywheel main body Shape spring cushion, damper include an annular secondary flywheel, are provided with the disc core with hub at the center of secondary flywheel, fly in pair It is connected using upper and lower damping disk(-isc) between wheel and disc core, is provided with what 2-4 was arranged symmetrically in the hub of disc core and upper and lower damping disk(-isc) Lunette is equipped with arc shock-absorbing spring in lunette, which mainly solves simple substance integral flywheel when transmitting torque, Impact is big, noise is big, the problem of increasing the abnormal sound of speed changer, influencing speed changer service life, in terms of being mainly used for Automobile flywheel.

Invention content

That the purpose of the present invention is to solve automobile clutch spring combined disk weight is big, composite structure is unreasonable, often The unsafe problems such as spring dislocation falls off, pedestal deforms are caused, a kind of reasonable in design, thrust ring up and down of combination order is provided Using the integral structure of compacting, and equipped with the spring base with thrust ring one, left-hand and right-hand spring interval is made to arrange by suppressing It arranges, be interference fitted on thrust ring and integral spring combined disk.

The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：A kind of spring combined disk, The lifting force ring of lower thrust ring and annulus shape including annulus shape, it is characterized in that being equipped with several in the lower thrust ring Lower spring cup is equipped with several upper spring seats in lifting force ring, and spring, lower spring cup are equipped between lower spring cup and upper spring seat It is equal with the quantity of upper spring seat, and quantity is even number, the center line of the two overlaps, and the spring includes left-handed spring, the right side Revolve spring, left-handed spring and the arrangement of dextrorotation spring intervals.

Spring includes that left-handed spring and dextrorotation spring ensure that combination order will not be reversed and be tilted in by compression process, under Spring base and upper spring seat directly carry out left and right spring under the action of special pressing device the assembly of dilatancy interference fit, Keep spring and thrust ring complete combination integral, there is good structural strength.

Preferably, the upper spring seat in lower spring cup and lifting force ring in the lower thrust ring is truncated cone-shaped, under One end internal diameter of the big end of the truncated cone-shaped of spring base and spring is interference fitted, the big end of the truncated cone-shaped of upper spring seat and spring it is another One end internal diameter interference fit.Upper lower spring cup is the position to extend out from respective thrust ring, uses special pressing device Reach the state of interference fit in engagement process in spring and spring base, truncated cone-shaped has big small end, is easy to keep spring fast Speed positioning.

Preferably, being equipped with gear between annulus endoporus and upper spring seat in the middle part of the lifting force ring of the annulus shape Ring, the height of baffle ring are less than or equal to the height of upper spring seat.Baffle ring prevents spring upwards thrust ring center from shifting, and increases simultaneously The integral strength of lifting force ring.

Preferably, the height of the lower spring cup and upper spring seat is equal, the size both ends of upper and lower spring base are logical Hole is equipped with arc chord angle at each curved arc.Upper lower spring cup stretches gained by metal plate, be highly not easy it is too big, first in spring base when stretching Center rushes an aperture and is stretched again, and each turning angle is all set as arc chord angle, to prevent metal plate drawing crack and increase product intensity, Lower spring cup and upper spring seat have equal height, same secondary stretching die can be used making the when of stretching, to reduce production Cost.

Preferably, the lower thrust ring and lifting force ring outer diameter is equal, lower spring cup uniformly divides on lower thrust ring Cloth, upper spring seat are uniformly distributed on lifting force ring.The endoporus of lifting force ring need to be molded baffle ring, same to be obtained with the method stretched It arriving, lower spring cup and upper spring seat correspond on the ring flat-plate of thrust ring, because left-handed spring and dextrorotation spring intervals arrange, institute With no matter the number of left and right spring be odd number or even numbers, the quantity of upper lower spring cup is all even number.

Preferably, the lower spring cup is an integral structure with lower thrust ring, upper spring seat and lifting force ring are one Body formula structure.Make stretching press process with plank and obtain monolithic construction, makes product that there is high-precision, high intensity, spy at low cost Point.

The invention has effective effect that：There is upper and lower thrust ring precision height, the good feature of symmetry to keep whole assembly automatic Change degree is high, qualification rate is high, and the job stability for combining finished product has been completely secured in the left-handed spring and dextrorotation spring for being spaced distribution.

Therefore, the present invention is a kind of reasonable in design, and overall cost is low, reliable and stable clutch spring assembly Disk.

Specific implementation mode

Below by embodiment, the technical solutions of the present invention will be further described.

Referring to Fig. 1, Fig. 2, a kind of spring combined disk of the present embodiment, including the lower thrust ring of annulus shape and annulus shape Lifting force ring, upper and lower thrust ring all use light sheet material drawing and forming.28 lower spring cups 31 are equipped in lower thrust ring 3, on 28 upper spring seats 41 are equipped in thrust ring 4, as shown in figure 3, being equipped with spring, upper bullet between lower spring cup 31 and upper spring seat 41 The center line of 31 the two of spring abutment 41 and lower spring cup overlaps.

Spring is divided into left-handed spring 2 and dextrorotation spring 1, on the upper spring seat 41 and lower spring cup 31 of upper and lower thrust ring, Left-handed spring 2 and dextrorotation spring 1 are alternatively arranged, that is, are filled a left-handed spring 2 and refilled a dextrorotation spring 1, constitute a circular ring shape It is whole.

As shown in figure 4, the lower spring cup 31 in lower thrust ring 3 is truncated cone-shaped, in the big end of truncated cone-shaped and the lower end of spring Diameter is using interference fit.

Referring to Fig. 5, Fig. 6, the upper spring seat 41 in lifting force ring 4 is identical as the truncated cone-shaped of lower spring cup 31, upper spring seat The big end of 41 truncated cone-shapeds and the upper-end inner diameter of spring are using interference fit.

A round baffle ring 42, baffle ring are set between the annulus endoporus and upper spring seat 41 at 4 middle part of lifting force ring of annulus shape 42 height is equal to the height of upper spring seat 41, is equal to the pitch of two springs.

Close-fitting mode is squeezed using automation when assembly, ensures that left-handed spring, dextrorotation spring are matched with upper and lower thrust ring interference Integrator.

Above-described embodiment is the description of the invention, is not limitation of the invention, any simple transformation to the present invention Structure afterwards all belongs to the scope of protection of the present invention.
