Abstract
The invention provides a centrifugal two-stage automatic speed change device. The centrifugal two-stage automatic speed change device is mainly composed of a metal shell, an input gear shaft, an output gear shaft, a centrifugal clutch and a transmission gear. The input gear shaft and the output gear shaft are respectively fixed in the metal shell through bearings. The input gear shaft is connected with a power machine and a transmission gear shaft respectively. A clutch tray and the input gear shaft are fixed together, and a clutch throwing block is arranged on the clutch tray. A clutch driven drum is connected with the transmission gear shaft through an inner gear ring and connected with the output gear shaft through an outer gear ring. According to the centrifugal two-stage automatic speed change device, the centrifugal clutch and an in-line gear set are organically combined, the two-sage automatic speed change function is achieved, and therefore the overload and overspeed operation of the power machine of an electromotor is avoided and the using requirements of vehicles under various working conditions are met.
Description
Technical field
The invention belongs to mechanical manufacturing field, be specifically related to a kind of centrifugal two-stage automatic transimission.
Background technique
At present,, there is following defect in the one-level speed changer that on market, electric motor car adopts: the moment of torsion 1, needing when vehicle start, climbing is that while normally travelling 5 to 8 times are because of transmission gear ratio one-level; So, can only lean on the large electric current of motor to improve Motor torque, thereby guarantee starting acceleration and grade climbing performance.2,, during normal vehicle operation, because of transmission gear ratio one-level, can only improve the speed of a motor vehicle by improving motor speed.Thereby cause the matching problem of motor and speed changer: if expanded motor power meets the special road conditions usage requirement of vehicle, the power loss in the time of will causing normal vehicle operation and energy waste.If strengthen transmission gear ratio, meet the special road conditions usage requirement of vehicle, will cause motor speed too high, will greatly reduce electric efficiency and working life.Therefore, one-level speed changer has seriously restricted coupling and the development of electric vehicle motor system.
Summary of the invention
The object of this invention is to provide a kind of centrifugal two-stage automatic transimission, to solve the problems of the technologies described above.
The present invention is mainly comprised of metal shell, input gear axle, output gear shaft, centrifugal clutch and driving gear, and solving the technological scheme that its problem adopts is that input gear axle and output gear shaft are individually fixed in metal shell by bearing; Input gear axle is connected respectively with driving gearshaft with dynamic power machine; Clutch pallet and input gear axle are fixed together, and on clutch pallet, clutch are set and get rid of piece; Clutch driven drum is connected with driving gearshaft by ring gear, and clutch driven drum is connected with output gear shaft by external toothing.Dynamic power machine is motor, diesel engine, petrol engine etc., same as the prior art.
The working method of centrifugal two-stage automatic transimission is: the dynamic power machines such as motor are connected with input gear axle, and centrifugal clutch pallet and input gear axle are fixed together.When input shaft rotating speed is not worked lower than design speed Shi， centrifugal clutching mechanism; Input power is combined and is delivered to output gear shaft by driving gear, by output gear shaft, is outputed power; Now the rotating ratio of this device input gear axle and output gear shaft is larger.Piece is got rid of in the clutch that reaches design speed Shi， centrifugal clutching mechanism when input shaft rotating speed, because rotary centrifugal force is subjected to displacement, is combined with clutch driven drum, and centrifugal clutching mechanism starts working; Input power, by clutch driven drum, is directly delivered to output gear shaft, by output gear shaft, is outputed power; Now the rotating speed of this device input gear axle and output gear shaft is smaller.Thereby realized the function of automatic clutch two-stage speed change.
Adopt automatic transimission of the present invention, can realize following functions: 1, when vehicle start, climbing, motor speed is lower than design speed, and centrifugal clutching mechanism does not work; Input power is delivered to output gear shaft by driving gear set; Now the rotating ratio of this device input gear axle and output gear shaft is larger.2, during normal vehicle operation, motor speed reaches the clutch of design speed Shi， centrifugal clutching mechanism and gets rid of piece, because rotary centrifugal force is subjected to displacement, is combined with clutch driven drum, and centrifugal clutching mechanism starts working; Input power, by clutch driven drum, is directly delivered to output gear shaft, by output gear shaft, is outputed power; Now the rotating speed of this device input gear axle and output gear shaft is smaller.Thereby, both avoided dynamic power machine overload, the hypervelocity work such as motor, met again the usage requirement of the various operating modes of vehicle.
Accompanying drawing explanation
Below in conjunction with example figure and embodiment, apparatus of the present invention are described further:
Fig. 1 is structural representation of the present invention;
In figure, 1 is that input gear axle, 2 is that metal shell, 3 is that clutch pallet, 4 is that driving gearshaft, 6 is that clutch driven drum, 7 is output gear shaft for clutch gets rid of piece, 5.
Embodiment
Describe the mode of execution of apparatus of the present invention below in detail, described mode of execution is exemplary, only for explaining apparatus of the present invention, and can not be interpreted as the restriction to apparatus of the present invention.
Embodiment 1
As shown in Figure 1: input gear axle 1 is individually fixed in metal shell 2 by bearing with output gear shaft 7; Input gear axle 1 is connected respectively with driving gearshaft 5 with motor; Clutch pallet 3 is fixed together with input gear axle 1, clutch is set on clutch pallet 3 and gets rid of piece 3; Clutch driven drum 6 is connected with driving gearshaft 5 by ring gear, and clutch driven drum 6 is connected with output gear shaft 7 by external toothing.
When input gear axle 1 rotating speed is during lower than design speed, clutch pallet 3 and clutch get rid of piece 4 and input gear axle 1 synchronous rotary, and centrifugal clutching mechanism does not work; Input power is delivered to output gear shaft 7 by driving gearshaft 5 and clutch driven drum 6, by output gear shaft 7, is outputed power; Now this device input gear axle 1 is larger with the rotating ratio of output gear shaft 7.
When input gear axle 1 turn up or higher than the clutch to design speed Shi， centrifugal clutching mechanism, get rid of piece 4, because rotary centrifugal force is subjected to displacement, with clutch driven drum 6 combinations, centrifugal clutching mechanism starts working; Input power, by clutch driven drum 6, is directly delivered to output gear shaft 7, by output gear shaft 7, is outputed power; Now this device input gear axle 1 is smaller with the rotating speed of output gear shaft 7.
