Abstract
The utility model relates to an energy saving speed changer of automobiles, which improves a mechanical speed changer. A one way clutch composed of a driving gear sleeve, a cylindrical rolling ball frame, a cylindrical rolling ball and a driven one way gear hub is arranged between a first shaft and a second shaft, the teeth on the outer margin of the driven one way tooth hub are made into a one way involute shape, and the cylindrical steel ball is inlaid in an involute-shaped tooth socket. An engine drives the driving gear sleeve to rotate, the rolling ball makes the driven one way tooth hub tightly locked with the driving gear sleeve to ensure that the driven one way tooth hub rotates with the driving gear sleeve. When a driver looses the gas to slide a vehicle, the rolling ball returns to the tooth socket of the driven one way tooth hub, and the driven tooth hub is disengaged from the power. With the structure, the utility model fully utilizes the inertia of a vehicle, so that the fuel can be saved by 20%, and simultaneously, the operating procedure is simplified.
Description
The utility model relates to the improvement to automobile gearbox.
At present, general automobile is for adapting to the variation of driving conditions, and necessary frequent changes gear such as misoperation can make gear bump, even hang repeatedly and do not perform, the acceleration mechanical wearing and tearing; Main when being gear shift, the low speed brake action of driving engine has limited the inertia that travels of automobile, influences giving full play to of inertia energy, has greatly wasted the energy.
The purpose of this utility model is to provide a kind of simple in structure, easy operating, can makes full use of the Automotive transmission of automobile inertial, energy savings.
The purpose of this utility model realizes by technical scheme shown in the drawings, it to existing by one, two, shifting gears at different levels, the change-speed box that gear box casing is formed improves, between one 1 and two 8, be provided with free-wheel clutch, this free-wheel clutch is by pinion carrier 2, cylinder ball rack 3, cylinder ball 4, passive unidirectional tooth hub 5 is formed the cylinder ball rack and is arranged between pinion carrier and the passive unidirectional tooth hub, passive unidirectional tooth is drawn a bow to the full and is enclosed within on two, the marginal tooth that passive unidirectional tooth is drawn a bow to the full is made unidirectional involute shape, and the cylindrical steel ball on the ball rack is embedded in the involute shape tooth nest; Pinion carrier is meshed with second speed gear and 3rd gear respectively by the engaging tooth 6 of its both sides, and the gear shift fork drops in the water jacket of pinion carrier.Principle of work of the present utility model is as follows: when third gear is travelled, the power of driving engine drives pinion carrier to anticlockwise motion (working direction) by one of change speed gear box, the involute direction of cylinder ball while to the marginal tooth that passive unidirectional tooth is drawn a bow to the full moves, thereby lock passive unidirectional tooth hub, make it to rotate with pinion carrier, power is spread out of by two, driving automobile advances; Receive cunningly when capable, without gear, because the rotating speed of pinion carrier is lower than the rotating speed that passive unidirectional tooth is drawn a bow to the full, ball is got back in the tooth nest of passive unidirectional tooth hub, and passive unidirectional tooth hub separates with power, and automobile is in a kind of sliding state that does not have the driving engine mechanical resistance; In the time of need quickening again, the power of driving engine is passed to pinion carrier through one, and the rotating speed of pinion carrier is greater than the rotating speed of passive ratchet, and ball moves to the involute direction of the marginal tooth of passive unidirectional tooth hub once more, thereby lock passive unidirectional tooth hub once more, make it to rotate with pinion carrier.When needing speed change, no matter be that third gear is reduced to second gear or second gear adds to third gear, under the effect of free-wheel clutch, do not add empty oil, do not step on just conversion arbitrarily of power-transfer clutch, operation freely.Of the present utility model simple in structure, reliable in quality has been simplified the driver behavior program greatly, alleviated the working strength of chaufeur, overcome the negative effect of transmission, got rid of the chatter phenomena of transmission system, it is more stable to travel, a great advantage of the present utility model is to save fuel oil, the structure of this change-speed box is fully used the inertia of automobile, and driving engine is in minimum speed when sliding, and has saved great amount of fuel oil, compare with traditional mechanical transmission, this change-speed box can be saved fuel oil minimum 20%.Structure of the present utility model is applicable to various vehicles.Application of the present utility model will produce huge economic benefit and social benefit.
Accompanying drawing 1 is the utility model front view;
Accompanying drawing 2 is the utility model free-wheel clutch structure principle chart.
Embodiment:
The vehicle energy saving change-speed box that is used for Beijing 212 type jeeps, 92 millimeters of pinion carrier outside diameters, 55 millimeters of root diameters, 60 millimeters of tooth top diameters, 40 millimeters of pinion carrier thickness, 30 of the every sides of the number of teeth, corresponding with the number of teeth on second gear and the 3rd gear.35 millimeters in the big footpath of passive unidirectional tooth hub internal splined hole, 30 millimeters of paths, key is wide 8.7 millimeters, 54 millimeters of passive unidirectional tooth hub external diameter maximums, the involute shape tooth on the passive unidirectional tooth hub has 10,15 millimeters of the thickness of passive unidirectional tooth hub.
Claims (1)
1. vehicle energy saving change-speed box, comprise one, two, shifting gear at different levels, gear box casing, it is characterized in that between one and two, being provided with free-wheel clutch, this free-wheel clutch is drawn a bow to the full by pinion carrier, cylinder ball rack, cylinder ball, passive unidirectional tooth and is formed the cylinder ball rack and be arranged between pinion carrier and the passive unidirectional tooth hub, passive unidirectional tooth hub sleeve is on two, the marginal tooth of passive unidirectional tooth hub is made unidirectional involute shape, and the cylindrical steel ball on the ball rack is embedded in the involute shape tooth nest; Pinion carrier is meshed with second speed gear and 3rd gear respectively by the engaging tooth of its both sides, and the gear shift fork drops in the water jacket of pinion carrier.
