Below according to Fig. 1,2, the 3 details service conditions that describe in detail according to the concrete device that the utility model proposes.Because the device that the utility model proposes is made up of automatic anti-slip differential mechanical device, Electromechanical Control mechanism and engine ignition standby circuit, is described respectively.
The automatic anti-slip differential mechanical device
A step on the accelerator just automatically engages, is installed in drive axle in or two terminal positions (being example explanation to be installed in the bridge now) of bridge once loosening automatic anti-slip differential mechanical device (D) that throttle separates automatically in vehicle '.Butt flange (4) is connected by dynamic bevel gear (26) with drive axle, and the other end and imput shaft (16) link.Imput shaft (16) is a stepped shaft, and two ends are bearing seat (16
1), the centre is a multiaspect cam (16
3), end is a minor axis (16
2), cut some sulculuses on its minor axis and be drilled with some apertures.Slideway or slide rail (13) are housed on each cam planes.Slide block (23) or multiaspect scapus move or roll along slideway or slide rail.The slide block (23) that plays automatic clutch and have the transferring power effect concurrently is set in the corresponding axial groove of synchronous retainer (12), and is corresponding with cam planes.The inside bottom of retainer (12) is shaped on control capsule synchronously, as shown in Figure 2.Be provided with the crescent of several arranged tangential and the radial direction through hole of equal number in the box.The inertia centering block (19) of limit spring (20) is housed on it, is that axle mounting is in crescent with Xiao Ding (17).When imput shaft rotated counterclockwise, centering block (19) overcame the suction of magnetic patch (18) around its Xiao's axle clockwise direction swing under centrifugal action.Be contained in the inner termination of the limit spring (20) on the centering block, insert by radial direction through hole in the minor axis respective grooves of cooresponding imput shaft, with limits synchronization retainer (12) and slide block (23) and cam planes relative angular displacement under normal circumstances.Be shaped on several triangle radial slots on the inner cylinder face of retainer (12) bottom synchronously, so that clear spring (21) to be installed, the inner termination of clear spring (21) is inserted in the respective aperture of minor axis, is positioned at the midway location of cam planes to guarantee slide block (23) under off working state.The small end female splines of the driving center of ladder cartridge type (14) is connected with semiaxis (8).Driving center (14) also is bearing on the imput shaft (16) with bearing (3) and (9), and slide block (23) is housed between driving center (14) inner cylinder face and the cam planes.
Electromechanical Control mechanism
In vehicle ', when not allowing coasting with engine off, when requiring reversing or needing the driving engine auxiliary braking, the Electromechanical Control mechanism of playing the control function is installed in the inside and outside side of middle end face of driving center (14).Control desk (5) and friction lining (7) link together, and are connected with the inner of slip Xiao axle (11), are installed in the inboard of driving center (14) and synchronous position between the outside of retainer (12), and can slide with slip Xiao axle (11).Driver chuck (6) is connected with the outer end of slip Xiao axle (11), is positioned at the middle end face outside of driving center (14).Its control handle or switch are located at appropriate location in the operator's compartment.
The engine ignition standby circuit
Control driving engine automatically extinguishing, the standby circuit of lighting a fire automatically are made up of switch and electric wire, are located near the Das Gaspedal in the operator's compartment.
The automatic of this device by the working process that closes with separating automatically is: when stepping on the throttle, the cireular frequency of imput shaft (16) is higher than the cireular frequency of driving center (14), when slide block (23) slides backwards on the narrow space position in force of inertia effect lower edge cam planes, slide block (23) is locked between cam planes and the driving center (14), then this device is in engagement state, transferring power and drive to travel.When the driving center that loosens throttle or be connected with drive wheel (14) cireular frequency surpasses the cireular frequency of imput shaft (16), slide block is under the force of inertia effect, along cam planes slide into forward and driving center (14) between the broad locus, at this moment under clear spring (21) and limit spring (20) combined action, eliminating slide block (23) stops it to continue to slide together with the force of inertia of step retainer (12), make this device be in released state, by standby circuit control driving engine automatically extinguishing in parallel, vehicle is by inertia traveling.
The working process of the forced engagement of this device is: if climatic conditions or road conditions do not allow coasting with engine off or require to move backward when maybe needing to utilize the driving engine auxiliary braking, can move to the inside by Electromechanical Control mechanism operating dial (6), driving control desk (5) and friction lining (7) also moves to the inside and is pressed on the bottom end face of synchronous retainer (12), forced synchronization retainer (12) changes an angle together with the relative cam planes of slide block (23) under the friction force effect, overcome the resistance of clear spring (21) and limit spring (20) and continue to front slide, super more middle zero position and enter the narrow space zone of opposite side, slide block (23) then is locked between cam planes and the driving center (14) and is in the reverse engagement state, the realization reverse power is transmitted, and realizes that reversing or idling slide.At this moment driving engine is in tickover or utilizes the driving engine auxiliary braking and forced idling running, thereby has improved automobile downhill or at ground-surface braking effects such as ice and snow, to guarantee safety traffic.When change-speed box is hung reverse gear, against the force of the spring and enter reverse engagement is realized the automobile backward going as a same reason.
