Description
Technical field
The present invention relates to a kind of automatic shifting mechanism for vehicle.
Background technique
Original electro-tricycle and four-wheel wagon, motor and wheel are all the time in bonding state in the process of moving, do not have clutch to make motor separated with driving gear yet, when so vehicle slides under acceleration mode not also with motor and power section running, to vehicle sliding, brought resistance like this, the distance travelled of vehicle is shortened, also increased mechanical wear.
For overcoming the problems referred to above, although existing two gear variable speed electric motors, particularlies have at certain gear, one-way element has been installed, one-way element belongs to a kind of in free wheel device, its effect is to make certain element can only be by certain direction rotation, locking in another direction.But this gear is just realized reversing and is not had defect, and while shifting gears in Vehicle Driving Cycle process owing to there is no clutch, gear shock sound is large, to gear, brings damage.
Summary of the invention
The invention is intended to provide a kind of electric vehicle gear box no-clutch synchronizer and realization to slide the device that gearshift is reversed gear, so that the power plant of vehicle can drive vehicle wheel rotation forward or backwards, but wheel cannot drive power plant in the situation that advancing acceleration, make vehicle can realize farther coasting distance, the more power saving of travelling.
Patent scheme: the device that gearshift is reversed gear is slided in the electric vehicle gear box no-clutch synchronizer in this programme and realization, it is characterized in that: include output shaft, output shaft connects driving gear by one-way element, reverse gear has been fixedly connected on output shaft, driving gear is provided with coaxial outside thread spline with it, between driving gear and reverse gear, be provided with the joint sleeve that reverses gear, the joint sleeve that reverses gear connects with outside thread spline coupling by internal thread spline, when motor reverses gear rotation for ordering about vehicle, close reverse gear under the effect of the axial thrust load that the joint sleeve that reverses gear produces at screw thread spline, spacing between outside thread spline and reverse gear is less than the axial length of internal thread spline, reverse gear joint sleeve and reverse gear is provided with and can synchronizes the connecting structure of rotating.
Outside thread spline and the spacing of gear between gear of reversing gear are less than the axial length of internal thread spline, are that the joint sleeve that reverses gear when reversing gear is deviate from outside thread spline, the problem that causes transmission of power to interrupt.When motor moves ahead rotation for ordering about vehicle, the joint sleeve that reverses gear is against on driving gear end face, when motor reverses gear rotation for ordering about vehicle, reverse gear joint sleeve under the axial thrust load effect of screw thread spline away from driving gear end face, and rely on the reverse gear being fixedly connected on output shaft, thereby the action of the rotation of reversing gear is passed to output shaft by driving gear, reverse gear joint sleeve and reverse gear.
Be used in the gearbox of variable block and got rid of the impact force that in Vehicle Driving Cycle, variable block is beaten tooth, make variable block reduce noise and reduce gear wear, be equivalent to serve as clutch and increase the service life.
This device can be used in electric motor car, by said structure, makes the power plant of vehicle can drive forward or backwards vehicle wheel rotation, but wheel cannot drive power plant in the situation that advancing acceleration, when vehicle advances, the unidirectional slip of energy, also can move backward, and has extended distance travelled.
Further, described in reverse gear joint sleeve and reverse gear be provided with and can synchronize the connecting structure of rotating, be tooth and the groove of axially pegging graft at reverse gear joint sleeve and reverse gear opposing end surface respectively.
Further, the joint sleeve that reverses gear is provided with friction spring, and friction spring has the degrees of freedom of moving axially but without rotational freedom.Friction spring can give its certain frictional force that turns in relative rotation with the joint sleeve that reverses gear simultaneously, and the joint sleeve that reverses gear is realized and being moved axially smoothly under the described acting in conjunction that turns to frictional force and described screw thread spline.Like when nut, be connected in cannot axially movable screw rod on, when screw rod rotates, as stoped nut rotation, nut can move axially on screw rod.
Further, on output shaft, fixed cover is provided with one-way element inner sleeve, and the one-way element that one-way element inner sleeve connects by its periphery connects with driving gear.
Further, described one-way element is unidirectional needle bearing.
Further, between the spline of one-way element inner sleeve and output shaft, be provided with gap.Be conducive to be enclosed within one-way element back rotation on axle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 is the shape schematic diagram of friction spring in the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: output shaft 1, one-way element inner sleeve 2, one-way element 3, driving gear 4, outside thread spline 41, the joint sleeve 5 that reverses gear, internal thread spline 51, circular groove 52, attachment tooth 53, reverse gear 6, connection slot 61, friction spring 7.
Embodiment is substantially as shown in Figure 1: include by bearing and turn round the output shaft being connected in frame, on output shaft, key is connected with one-way element inner sleeve, one-way element is herein unidirectional needle bearing, the one-way element that one-way element inner sleeve connects by its periphery connects with driving gear, driving gear is driven by motor driving shaft and unidirectional drive output shaft is rotated in the forward, when motor quits work, vehicle continues to slide forward, and motor stops operating under the effect of one-way element;
The outer wall of driving gear end face boss is provided with outside thread spline, the internal thread spline that the joint sleeve that reverses gear is provided with by its inwall connects with driving gear end face boss, when motor moves ahead rotation for ordering about vehicle, the joint sleeve that reverses gear is against on driving gear end face, when motor reverses gear rotation for ordering about vehicle, reverse gear joint sleeve under the effect of screw thread spline away from driving gear end face, and relying on the reverse gear being fixedly connected on output shaft, the end face that reverse gear joint sleeve and reverse gear fit is established attachment tooth and the connection slot of axial grafting;
