Description

A kind of gearshift of electric vehicle three class gear box
Technical field
The utility model relates to a kind of gearshift of electric vehicle three class gear box, belongs to electric vehicle engineering field.
Background technique
At present, obtain due to the feature of environmental protection of electric vehicle and develop faster, and the gearbox matched with it is also answered and rise, obtain and develop faster.Different from traditional fuel-engined vehicle, the power source of pure electric automobile is motor, the feature of motor efficiently in quite broad velocity range can produce torque and can start by bringing onto load, therefore only need conversion minority gear when vehicle travels, starting also no longer needs complicated clutch configuration.Motor-driven all features determine the usage requirement that conventional transfer case shift mechanisms no longer meets electric vehicle above.At present, the gearshift of the electric vehicle that market exists is all drive driveshaft by shift motor, and driveshaft drives shifting block, shifting block drives shift fork to do straight line motion along the axis of declutch shift shaft, then drive when being moved to induction zone by sensing unit, shift motor power-off thus realize gearshift function, this gearshift also exists complex structure, component are many, rate of fault is high, and inefficient defect of shifting gears, can not meet user demand.Therefore, need to develop the special gear shift mechanism of electric vehicle.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, and provide a kind of structure simple, failure rate is low, gearshift efficiency is high, the gearshift of the electric vehicle three class gear box that user cost is low.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of gearshift of electric vehicle three class gear box, comprise the servocylinder, fork, fork axle and the elastic element that are used as to drive power source, described fork to be sheathed on described fork axle and to be fixedly connected with declutch shift shaft by fixed block, one end of described declutch shift shaft is fixedly connected with servocylinder, the other end of fork axle is arranged at intervals with some grooves vertically, and elastic element is resisted against in groove described in one of them.
Described elastic element is elasticity bulb self-locking screw.
Described fixed block is pin.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The gearshift of electric vehicle three class gear box of the present utility model, directly adopts servocylinder to carry out shift fork axle, eliminates a series of assemblies such as the shifting block of existing gearshift, driveshaft, make gearshift compact structure of the present utility model, failure rate is low.In addition, because shift fork is directly fixed on declutch shift shaft, servocylinder will drive shift fork to take exercises together along with declutch shift shaft while drive declutch shift shaft axial motion, such structural design, make whole gear shift operation pilot process short, accuracy rate is high, and gearshift rapidly, the comfort property of electric vehicle can be improved, be suitable for large-scale promotion application.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment one structural representation.
In above accompanying drawing: 1, servocylinder, 2, shift fork, 3, declutch shift shaft, 4, elastic element, 5, fixed block, 6, groove.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, the gearshift of a kind of electric vehicle three class gear box of the utility model, comprise the servocylinder 1, fork 2, fork axle 3 and the elastic element 4 that are used as to drive power source, fork 2 to be sheathed on described fork axle 3 and to be fixedly connected with declutch shift shaft 3 by fixed block 5, in the present embodiment, fixed block 5 is pin.One end of declutch shift shaft 3 is fixedly connected with servocylinder 1, and the other end of fork axle 3 is arranged at intervals with some grooves 6 vertically, and elastic element 5 is resisted against in groove 6 described in one of them.
Preferably, as an embodiment, described elastic element 5 is elasticity bulb self-locking screw.
The gearshift of electric vehicle three class gear box of the present utility model, directly adopts servocylinder 1 to carry out shift fork axle 3, eliminates a series of assemblies such as the shifting block of existing gearshift, driveshaft, make gearshift compact structure of the present utility model, failure rate is low.In addition, because shift fork 2 is directly fixed on declutch shift shaft 3, servocylinder 1 will drive shift fork 2 to take exercises together along with declutch shift shaft 3 while drive declutch shift shaft 3 axial motion, such structural design, make whole gear shift operation pilot process short, accuracy rate is high, and gearshift rapidly, the comfort property of electric vehicle can be improved, be suitable for large-scale promotion application.In the present embodiment, servocylinder 1 is a kind of by the modular product of actuating motor and leading screw integrated design, it can convert the rotary motion of actuating motor to straight line motion, actuating motor optimum benefits-precise rotation is controlled simultaneously, accurate revolution controls, accurate torque controls to be transformed into-precise speed control, Accurate Position Control, and accurate thrust controls; Realize highi degree of accuracy straight line motion.In addition, servocylinder 1 works under complex environment only needs regular injecting grease for lubricating, and there is no easily damaged parts needs to safeguard replacing have better working life than hydraulic system and pressure system.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
