Abstract

The utility model provides a delayed type overrun clutch. The delayed type overrun clutch comprises an inner ring for being connected with a motor and an outer ring for being connected with a load, wherein the inner ring is provided with a cavity; the cavity is internally provided with a roller and a spring; one end of the spring is fixedly connected with the inner wall of the cavity and the other end of the spring is connected with the roller; a wedge-shaped self-locking structure is arranged on a face, which is in rolling contact with the roller, in the cavity. The utility model provides the delayed type overrun clutch which is energy-saving, is simple in structure and is convenient to manufacture.

Description

Delayed type free wheel device

Technical field

The utility model relates to clutch field, refers to especially a kind of delayed type free wheel device for electric motor car, petrol engine, diesel engine.

Background technique

Determining of general electric vehicle motor power, be mainly power required while considering that car starts, and after starting, electric motor car does not need so large power, and this has just caused certain waste (other as petrol engine, diesel engine are also like this).How can reduce motor power (output) and also enable electric motor car and start smoothly, be problem demanding prompt solution.

Model utility content

The utility model proposes a kind of delayed type free wheel device, having solved smooth startups the such as electric motor car of the prior art needs the problem that consumed power is large.

The technical solution of the utility model is achieved in that a kind of delayed type free wheel device, comprise inner ring for being connected with motor and outer ring for being connected with load, on described inner ring, have die cavity, in described die cavity, be provided with roller and spring, one end of described spring is fixedly connected with die cavity inwall, and its other end is connected with roller; The face contacting with roller rolling in described die cavity is provided with wedge shape self-locking structure.

Further comprise, the number of described die cavity is at least 3, and described die cavity is evenly distributed on inner ring.

Further comprise, on described inner ring, be also provided with cover plate, described cover plate is annular cover plate, and its lid is covered in the both sides of inner ring.

Further comprise, described cover plate is fixedly connected with inner ring.

Beneficial effect: the utility model has solved the defect existing in background technique, by clutch designs of the present utility model, can effectively reduce the power (as motor, petrol engine, diesel engine etc.) of power source, thereby reach energy-conservation object, also can reduce the volume of power source, and clutch is simple in structure, be convenient to manufacture.

Embodiment

As shown in Figure 1, 2, a kind of delayed type free wheel device, comprise inner ring 2 and outer ring 1, inner ring 2 is connected with motor, and outer ring 1 is connected with load, has die cavity 5 on inner ring 2, on inner ring 2, be also provided with cover plate 6, cover plate 6 is fixedly connected by welding with inner ring 2, and cover plate 6 is annular cover plate, and its lid is covered in the both sides of inner ring 2.In die cavity 5, be provided with roller 3 and spring 4, one end of spring 3 is fixedly connected with die cavity 5 inwalls, and its other end is connected with roller 3; The face contacting with roller 3 rollings in die cavity 5 is provided with wedge shape self-locking structure.

The number of die cavity 5 is at least 3, the utility model is preferred 9, die cavity 5 is evenly distributed on inner ring 2.

By research, find, if allow motor idle running a period of time, allow rotor reach after certain speed, it will store certain energy, now allows motor on-load just can start smoothly again, has so just reached the object that reduces motor power (output).

Principle is as follows:

Motor is connected with inner ring 2, and load is connected with outer ring 1.

When motor is static, roller 3 drops to minimum point in the effect of spring 4, does not contact with outer ring 1.On-load not when motor has just started, motor makes spring 4 promote rollers 3 by inner ring 2 to move in a circle, and through after a while, makes it the rotating speed that reaches certain, roller 3 Compress Springs 4 simultaneously, roller 3 embeds wedge shape self-locking structures, thereby drives outer ring 1 rotation.

As long as adjust the steel wire diameter of spring 4, just can adjust the rotating speed of motor when roller 3 is firm embeds wedge shape self-locking structure, thus the energy of deposit before change motor on-load.

The utility model can effectively reduce the power (as motor, petrol engine, diesel engine etc.) of power source, thereby reaches energy-conservation object, also can reduce the volume of power source, and clutch is simple in structure, is convenient to manufacture.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
