Abstract

The utility model provides a torsion spring type automobile drag reduction and energy-saving device, which is composed of a main body mechanism and an auxiliary mechanism. The main body mechanism is an automatic overrunning clutch which employs a distinctive head-raised torsion spring as a power transmission component and is formed by stringing round parts which are at a same axis line, the auxiliary mechanism is formed by an 'H' type support shaft, a screw-and-nut pair with a shifting fork and a driving member, wherein the screw-and-nut pair with a shifting fork is assembled on the support shaft, and the driving member drives the screw-and-nut pair to rotate. Because the head-raised torsion spring features in fine deformation and shock absorbing, when the head-raised torsion spring is utilized as power transmission component to mesh with helical teeth. Compared with a ratchet-pawl mechanism, the joint impact force of the head-raised torsion spring is reduced, compared with a wedge type overdrive clutch mechanism, the using reliability of the head-raised torsion spring is reinforced, and the service life of key moving components are prolonged because of the intermittent working state of the head-raised torsion spring.

Description

Torsion spring type automobile resistance-reducing energy-saving device

Technical field

The utility model relates to a kind of automobile resistance-reducing energy-saving device in the automobile fuel saving product.

Background technique

At present, domestic technology automobile resistance-reducing energy-saving device (is representative as the patented technology with Li Shuanquan with Ma Chun) kind open and launch is more, structurally conclude and get up to mainly contain ratchet and pawl arrangement and these two kinds of structural types of voussoir clutch mechanism, but facts have proved, the former exists in conjunction with the impact force defective that produces the bump iron filings bigger than normal and easy, the latter then exists under the high pulling torque effect, be easy to generate between voussoir and the extruding circle combine inefficacy and working life unsettled defective, therefore, such technology still exists needs further perfect space.

Summary of the invention

The purpose of this utility model is exactly the deficiency for solution above-mentioned background technology, and provides a kind of joint impact force less, the automobile resistance-reducing energy-saving device that functional reliability is higher.

The purpose of this utility model is to realize like this, torsion spring type automobile resistance-reducing energy-saving device, being mounted in a medium tache on the automobile power transmission chain, is with a kind of automatic overrunning clutch of special nose torsion spring as force-transmitting member, is established mechanism's two big parts and forms with auxilliary by main body mechanism.

Described main body mechanism mainly is to be made of the circular lock ring that is in same shaft axis, driving link, driven member, bearing, lining, nose torsion spring, ring washer, oil sealing, mandrel and plug string dress.Driving link adopts suitable mode of structure to be connected with an end of driven member with the automobile power transmission part, the movable mutually butt joint of the other end, and in the butt joint end, preparation has seam, extend to both sides from stop portion, on the outer surface, be shaped on respectively one section with external tooth axis parallel, ring-shaped distributed, that can be meshed individually or simultaneously with the internal tooth that is shaped on the lock ring, on internal surface, also be shaped on respectively one section with axis parallel, that true dip direction is opposite, can with the helical teeth of nose torsion spring two ends one way engagement; And in driving link and driven member inside, being sleeved on from left to right has oil sealing, nose torsion spring, lining, ring washer, bearing and a plug on the mandrel.Owing to there is the one way engagement effect of nose torsion spring, when the driving link rotating speed pulled up to the driven member rotating speed, nose torsion spring termination just began to give driven member with helical teeth one way engagement and transferring power, otherwise, driven member then surmounts rotation, thereby has realized the overdrive clutch function of main body mechanism.

Described assisting established mechanism, mainly is to be made of the driver part that the support shaft of " H " type, the nut-screw pair that is fitted to band shift fork on the support shaft and drive nut screw pair rotate.The positive and negative rotation of drive nut screw pair, then but shift fork comes and goes displacement, thereby drive shift fork and stir the lock ring advance and retreat, when lock ring can be simultaneously with driving link and driven member on the external tooth engagement time, overdrive clutch function that just can the locking main body mechanism, realize normal reversing, otherwise, then can keep the overdrive clutch function of main body mechanism.

The utility model is compared with background technique has following advantage: the one, because the nose torsion spring has repeated deformation and elastic shock attenuation characteristic, cause it when taking on the engagement of force-transmitting member and helical teeth, reduce the joint impact force than ratchet and pawl arrangement, realized flexible engagement; The 2nd, the nose torsion spring is in when not meshing power transmission (driven member surmounts rotation) state, remaining the engagement for the treatment of with helical teeth, ensured the stability of engagement, the 3rd, the intermittent working state of nose torsion spring, prolonged the working life of critical movements parts, strengthened operational safety than Wedge type over running clutch mechanism.
