Abstract

The utility model relates to a transmission, in particular to an electromagnetic controlled non-step transmission in a mini car, which comprises an input shaft, a variable speed drive mechanism and an output shaft. Essentials of the utility model are as follows: The variable speed drive mechanism is a V-belt non-step drive mechanism; magnets are installed outside a driving gear movable disc on the V-belt non-step drive mechanism; a plurality of electromagnets in the same stage but opposite direction to the magnets are mounted in corresponding positions on the magnets; a regulating spring is installed outside the driven gear movable disc, and an electromagnet control device is included. With the magnetic force on the electromagnets, the driving gear movable disc can be pushed to a corresponding position; Meanwhile, with the regulating spring, the driven gear movable disc in the V-belt non-step drive mechanism can be regulated with operation of the driving gear, so that working diameter of the driving and driven gears can be changed in the condition of ensuring constant working distance of the transmission belt. The utility model is an inexpensive but useful non-step transmission for mini car and has the advantages of simple structure and non-step speed variation, convenient operation, small volume, continuous & non-intermittent speed variation.

Description

Miniature Car Solenoid Operated Variable-speed Unit

Technical field

The utility model relates to a kind of speed changer, particularly a kind of Miniature Car Solenoid Operated Variable-speed Unit.

Background technique

At present, the speed changer that uses on the automobile is the epicyclic train combined speed changer.The transmission of train of gearings combined speed changer is discontinuous, can only realize the stepless change in the segmentation limit, and transmission efficiency is lower, influences the power performance of car load, consumption fuel; Enlarge the stepless change coverage area as the gear number that will increase speed changer, just must adopt more executive component to control the power transmission line of epicyclic train, cause structure complicated more, maintenance and maintenance inconvenience more.

Summary of the invention

At above problem, the purpose of this utility model provides the infinite variable speed Miniature Car Solenoid Operated Variable-speed Unit of a kind of energy simple in structure.

A kind of Miniature Car Solenoid Operated Variable-speed Unit, comprise input shaft, variable transmission mechanism and output shaft, it is characterized in that: variable transmission mechanism is a V band infinitely variable speed gearing, outside the driving wheel movable plate of V band infinitely variable speed gearing, establish magnet is housed, on the position corresponding, establish and be equipped with some and magnet peer electromagnet in opposite directions with magnet, on the follower movable plate outside, establish Regulation spring is housed, and comprise electromagnet control device.

The utility model is to utilize magnetic levitation technology to make the driving wheel folding of V band infinitely variable speed gearing, promptly by the magnetic force of controlling electromagnet corresponding position is arrived in the repulsion of driving wheel movable plate, makes the driving wheel folding; And utilize Regulation spring that the follower movable plate of V band infinitely variable speed gearing is adjusted with the folding of driving wheel, in the working diameter of guaranteeing to change under the constant situation of driving belt work cell distance driven wheel, even the contact radius of driven wheel changes simultaneously, to change velocity ratio, reach the stepless change purpose.Not only simple in structure, the energy stepless change, and control conveniently, volume is little, and speed change does not have intermittently continuously, is a kind of highly desirable economical and practical Miniature Car Variable-speed Unit.

Embodiment

Describe in detail below in conjunction with drawings and Examples:

Fig. 1 is a kind of Miniature Car Solenoid Operated Variable-speed Unit of the present utility model, comprise input shaft 2, variable transmission mechanism and output shaft 13, main points are: variable transmission mechanism is a V band infinitely variable speed gearing, be with driving wheel movable plate 7 outsides of infinitely variable speed gearing to establish at V magnet 4 is housed, on the position corresponding, establish some and magnet 4 peers electromagnet 3 in opposite directions are housed with magnet 4, on follower movable plate 10 outsides, establish Regulation spring 11 is housed, and comprise electromagnet control device 16.The principle of utilizing the same sex to repel each other is arranged on peer's magnet 4 in opposite directions on driving wheel movable plate 7 outsides by the magnetic force repulsion of controlling electromagnet 3, and driving wheel movable plate 7 roof pressures to corresponding position, are made the driving wheel folding; And utilize Regulation spring 11 that the follower movable plate 10 of V band infinitely variable speed gearing is adjusted with the folding of driving wheel, in the working diameter of guaranteeing to change under the constant situation of driving belt work cell distance driven wheel, even the contact radius of driven wheel changes simultaneously, to change velocity ratio, reach the stepless change purpose.

Comprise also among Fig. 1 that the driving wheel movable plate that is made of control panel 5, plane bearing 6 and sliding sleeve 14 controls member, control panel 5 is positioned on the sliding sleeve 14, and magnet 4 is arranged on the control panel 5.Utilize plane bearing 6 that driving wheel movable plate 7 can be rotated, the control panel 5 that is positioned on the sliding sleeve 14 can only endwisely slip.Obviously, be arranged on magnet 4 on the control panel 5 and can be the identical block magnet of quantity and electromagnet 3, also ring magnet; What adopt among the figure is ring magnet.For making structure more simple, ring magnet 4 can be set directly on driving wheel movable plate 7 outer side surfaces.

Fig. 2 is a kind of electromagnet control device circuit diagram of computer control.Collect the information of motor and the position of reference speed and throttle by three sensors that are contained in respectively on driving wheel, follower, the bent axle, regulation and control electromagnet 3, the folding of control driving wheel movable plate 7 realizes smooth along sliding no gap gearshift transition.Obviously, can also adopt other electromagnet control device.
