Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of the utility model embodiment.
The implication marked in figure is: 10. motor, 11. motor output ends, 20. epicyclic reduction gears, 21. epicyclic reduction gear input ends, 22. epicyclic reduction gear mouths, 23. tooth bar mounting holes, 30. gears, 40. tooth bars.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In the embodiment shown in fig. 1, motor 10, epicyclic reduction gear 20, gear 30, tooth bar 40 are linked in sequence, specifically, motor output end 11 is connected with epicyclic reduction gear input end 21, epicyclic reduction gear mouth 22 is connected with gear 30, and gear 30 is connected with tooth bar 40, and epicyclic reduction gear mouth 22 is also for being connected with bearing circle drive member, in like manner, gear 30 end face also may be used for being connected with bearing circle drive member.
In the utility model embodiment, epicyclic reduction gear mouth 22 passes gear 30 and is extended with appropriate length for closure dish drive member.
In the utility model embodiment, epicyclic reduction gear 20 reduction ratio scope is 10 to 30, the utility model embodiment reduction ratio value is 20, and because bearing circle normal revolution scope is 60r/min to 120r/min, then motor 10 operating rotational speed range can be set to 1200r/min to 2400r/min.
In the utility model embodiment, epicyclic reduction gear 20 housing is provided with tooth bar mounting hole 23, under the drive of gear 30, tooth bar 40 can horizontally slip in tooth bar mounting hole 23.
In the utility model embodiment, epicyclic reduction gear mouth 22 is connected by spline fitted with gear 30, and epicyclic reduction gear mouth 22 is set to male splines, and gear 30 center is set to female splines through hole.
In the utility model embodiment, motor output end 11 is connected by spline fitted with planetary gear speed-reduction input end 21, and motor output end 11 is set to male splines, and epicyclic reduction gear input end 21 is set to female splines.
In the utility model embodiment, motor 10 housing is fixedly connected with by fixing structure with epicyclic reduction gear 20 housing.
During use, the pinion and-rack electric booster steering device of the utility model embodiment loads in steering swivel system, steering swivel system also comprises torque sensor, car speed sensor, electric machine controller, torque sensor direction of measurement dish turn sign, car speed sensor measures vehicle speed signal, and turn sign and vehicle speed signal are sent to electric machine controller, and motor controller controls motor 10 works, motor 10 increases moment of torsion by epicyclic reduction gear 20, and inputs power-assisted by gear 30 to tooth bar 40.
Because the efficiency of epicyclic reduction gear can reach 0.9, therefore compare the efficiency that turbine and worm significantly can improve steering swivel system, again because epicyclic reduction gear completely reversibility does not have self-locking performance, therefore driving road feel can be improved.
In addition, because pinion and-rack electric booster steering device structure of the present utility model is compacter, steering reaction is sensitiveer, and future more easily realizes intelligent driving.
The above is only the utility model description preferred embodiment; should be understood that the finiteness due to literal expression; and objectively there is unlimited concrete structure; for this area those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improve the scope that also should be considered as the utility model protection.
