Description
Technical field
The present invention relates to a kind of guideway vehicle pivoted arm axle box retainer spring installation adjusting method.
Background technology
Referring to Fig. 2, the pivoted arm axle box location structure in the existing rail vehicle truck utilizes coil spring 1,2 to realize that one is the vertical elasticity of axle box location, utilizes pivoted arm rubber location node 4 to realize that one is the horizontal and vertical elasticity of axle box location.This structural requirement is when bogie truck is assembled, and pivoted arm rubber location node 4 must be when coil spring is compressed into the operating altitude under the empty wagons load, to be installed on the bogie truck.Otherwise behind the car that falls; Coil spring 1,2 can produce vertical direction and carry amount of deflection, highly descends, and the framework of sitting above that 9,10 also descends thereupon; Axle box pivoted arm 3 is around 11 rotations of axle box axial line; Make pivoted arm rubber location node 4 produce the bigger anglec of rotation, and remain on this state that the anglec of rotation is arranged for a long time, thereby can shorten its service life.In addition, this pivoted arm axle box locate mode also needs cushioning adjustment under whole vehicle state when vehicle weighing and utilization overhaul; This just requires at framework by jack-up; Under the discharged situation of coil spring, still can clamp and maintain the preceding operating altitude of coil spring unloading, coil spring does not stretch when making framework by jack-up;, vacate the gap between rubber damper 5 below coil spring and the axle box pivoted arm 3 and add adjusting pad together with after moving certain altitude on the framework together with the rubber damper 5 below the coil spring.
Referring to Fig. 1; A kind of practice of prior art is on the compression machine coil spring to be depressed in the operating altitude in advance; Adopt clamping piece 17 coil spring to be clamped and the maintenance operating altitude, treat that car body sits on later on the bogie truck clamping piece 17 to be withdrawn by means of following 19 at the coil spring seat of honour 18, coil spring; The cushioning adjustment time is loaded onto it again and to be made coil spring maintain operating altitude, can be because of erecting of framework do not unload rise, and make between coil spring upper surface and the framework lower plane generation gap carry out cushioning.This practice can only be used for coil spring and be positioned at truck side sill below, exposed fully axle box pivoted arm structure outside; If coil spring is loaded on the spring of truck side sill and installs in the cylinder base, the clamping piece 17 that clamps in advance can hinder the installation of coil spring 1,2 on bogie truck.
Referring to Fig. 2, the another kind of practice of prior art is to fall behind the car, and the load of bearing equipment on car body and the car when coil spring 1,2 is installed pivoted arm rubber location node 4 to framework during to operating altitude; Cushioning when adjustment, erect car body earlier, make coil spring 1,2 be in unloaded state, the position shown in the B in Fig. 2 levers up the rubber damper 5 of coil spring 1,2 and its underpart with crowbar, exposes the slit, and then cushioning.The shortcoming of this practice is, can not realize that coil spring and pivoted arm rubber nodal point stack-mounted once accomplish, must be in car load completion back, the pivoted arm rubber nodal point is installed when coil spring is carried on operating altitude again, produce the secondary installing operation, and operation is loaded down with trivial details; During the cushioning adjustment, must erect car body the coil spring unloading could be operated with crowbar, and unwheeling will bring a series of loaded down with trivial details extra works, work capacity is big.
Summary of the invention
The object of the invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of easy be suitable for, reduce operation, safe and reliable guideway vehicle pivoted arm axle box retainer spring installation adjusting method are provided.
The objective of the invention is to realize like this: this guideway vehicle pivoted arm axle box retainer spring installation adjusting method adopts following step:
