Abstract
The utility model relates to a linear motor suspension device which comprises an adjusting screw sleeve which penetrates through a longitudinal beam sleeve, and a fixing bolt which is connected with a linear motor at the bottom of an inner sleeve of the adjusting screw sleeve, wherein an adjusting nut is sleeved on the top of the longitudinal beam sleeve; the top surface of the adjusting nut is fixed to the top surface of the longitudinal beam through fasteners; and the adjusting screw sleeve is in threaded connection with the adjusting nut. The linear motor suspension device is simple and reliable in structure, and the linear motor can be vertically positioned on the longitudinal beam; the requirements of the linear motor on height adjustment in the vertical direction can be met, so that a gap between a lower plane of the linear motor and an upper plane of an aluminum plate of the rail is accurately adjusted; the perpendicularity error of the fixing bolt and the adjusting screw sleeve is reduced, the assembling stress of the fixing bolt brought by the assembling error is reduced, and the reliability and the height adjustment availability of the linear motor suspension device are improved; and moreover, the labor intensity of operators is alleviated, and the device does not have the requirement on the technical level of the operators and is suitable for volume production.
Description
Technical field
The utility model relates to a kind of linear motor suspension device, relates in particular to a kind of linear motor suspension device that is applied to middle low speed magnetic floating rail traffic vehicles or urban track traffic railcar.
Background technology
The general employing of middle Low-speed maglev vehicle suspension rack is comprised of the identical module of a plurality of basic structures, and wherein each module arranges linear electric motors and a cover draw gear, and tractive force and the electric braking force of vehicle provide by linear electric motors.The setting height(from bottom) of linear electric motors, namely the gap between motor lower plane and track can directly affect the efficient performance of the above-mentioned tractive force of linear electric motors and braking force.Therefore, the setting accuracy of linear electric motors is one of the key factors that determine the efficient performance of linear electric motors.
Different mounting structures has determined the height regulative mode that linear electric motors are different.The rigid suspended mode of the normal employing of the linear electric motors of Low-speed maglev vehicle in existing.Be that every linear electric motors adopt eight cover suspension control apparatuss to be fixed on below the module longeron usually.
Existing linear motor suspension device comprises the steel swivel nut that is fixed in the longeron sleeve, and screw in Adjusting bolt Adjusting screw in the steel swivel nut, the bolt of rear end plate that the bottom is connected with linear electric motors is installed in Adjusting bolt Adjusting screw, is regulated distance between linear electric motors and track by rotating Adjusting bolt Adjusting screw.But there is assembly error in this device after installing, and particularly the error of perpendicularity with horizontal surface is difficult to guarantee, causes the bolt of rear end plate mounting hole centre deviation corresponding with motor the problem that can't assemble may occur too greatly.Usually the mode of taking to strengthen bolt of rear end plate and Adjusting bolt Adjusting screw gap is processed, and consequently the applying of Adjusting bolt Adjusting screw and longeron attachment face circumferencial direction is not tight, thereby causes bolt of rear end plate the assembling flexure stress to occur, has reduced the reliability of suspension device of motor.Simultaneously, the height that also affects linear electric motors is regulated.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of linear motor suspension device, reduces the assembling stress that assembly error brings bolt of rear end plate, the availability that improves the reliability of linear motor suspension device and highly regulate.
The technical solution of the utility model is, a kind of linear motor suspension device, comprise the Adjusting bolt Adjusting screw that passes in the longeron sleeve, and the bolt of rear end plate that the suit bottom is connected with linear electric motors in Adjusting bolt Adjusting screw, described longeron sleeve top suit setting nut, the end face of this setting nut is fixed to the end face of longeron by fastener, described Adjusting bolt Adjusting screw is threaded with setting nut.
Described Adjusting bolt Adjusting screw comprises the swivel nut installation portion that extend to the swivel nut main body outside at swivel nut main body and swivel nut main body top, and described swivel nut installation portion is placed in the upside of setting nut.
Be provided with one or more pieces between described swivel nut installation portion and setting nut end face and regulate pad.
By tightening bolt of rear end plate, the linear electric motors attachment face can be adjacent to the lower surface at Adjusting bolt Adjusting screw, the vertical location of realizing linear electric motors.Due to Adjusting bolt Adjusting screw and setting nut employing screw thread fit, by the rotation Adjusting bolt Adjusting screw, can realize on the one hand the step-less adjustment of the setting height(from bottom) of linear electric motors, improved on the other hand the bending stiffness of bolt of rear end plate.Setting nut is arranged on the longeron sleeve by fastener vertical, has guaranteed the squareness requirement of setting nut on longeron.The adjusting pad is set between Adjusting bolt Adjusting screw and setting nut, completes for linear electric motors and highly regulate rear fastening location to Adjusting bolt Adjusting screw.
When vehicle operating certain distance or time rear motor gap exceed designing requirement and need to safeguard the linear electric motors setting height(from bottom), first unscrew bolt of rear end plate, loosen again Adjusting bolt Adjusting screw, increase and decrease adjusting disk again between Adjusting bolt Adjusting screw and setting nut, then again tighten Adjusting bolt Adjusting screw and bolt of rear end plate, namely completed the setting height(from bottom) of linear electric motors and safeguarded.
Linear motor suspension device described in the utility model is simple and reliable for structure, can realize linear electric motors vertical location on longeron; Can satisfy the needs that linear electric motors are regulated at vertical height, accurately regulate with the gap between the plane on the aluminium sheet of realizing linear electric motors lower plane and track; Reduce the error of perpendicularity of bolt of rear end plate, Adjusting bolt Adjusting screw, reduced the assembling stress that assembly error brings bolt of rear end plate, improved the reliability of linear motor suspension device and the availability of adjusting highly; Reduced the labour intensity of operating personal, insensitive to the technical merit of operating personal, be suitable for batch manufacturing.
