Abstract
The invention discloses a wheel set assembly for a meter gauge axle disc braking bullet train bogie. The wheel set assembly is mainly composed of wheels, an axle, an axle box assembly, a braking disc and a driving device. The axle box assembly is of a penetrated type structure, and the axle penetrates through a front cover and a rear cover of an axle box. The front cover of the axle box is matched with a partition cylinder through a labyrinth seal structure, and the rear cover of the axle box is matched with a dustproof check ring through a labyrinth seal structure. The front cover of the axle box and the axle are sealed in a contact mode, and the rear cover of the axle box and the axle box are sealed in a contact mode. The axle extends to penetrate through the axle box assembly, and the braking disc is installed on the part, penetrating out of the outer side of the axle box, of the axle, installed in a key or spline structure matching mode and pressed through an axle end bolt and a gland. The front cover of the axle box is provided with an antiskid speed sensor, and a gearbox is provided with a grounding device in an integrated mode. The wheel set assembly solves the problem that the braking disc space does not exist between the two wheels, and the installation of an axle disc braking device on the meter gauge bullet train wheel set becomes possible. The braking thermal capacity limiting value is greatly increased, the highest operation speed of trains is increased, the requirement for the operation speed of 160 km/h can be met, the transmission problem of braking torque is solved, in addition, assembling and disassembling of the braking disc can be easier, and overhauling and replacing of an axle box bearing are facilitated.
Description
Technical field
The present invention relates to a kind of meter-gage reel braking motor car bogie wheel to composition, this is taken turns and is provided with shaft mounted type brake disc to composition, and axle box composition adopts penetration type structure, and highest running speed can reach 160km/h, is mainly used on meter-gage motor train unit or subway train.
Background technology
The existing a variety of bogie truck for meter-gage motor train unit in the world, these bogie truck many employings tread brakes, highest running speed is no more than 100 km/h.As a kind of brake equipment having more advantage than tread brake in many-sides such as braking heat absorption capacitys, Axle Disc Brake Equipment is if be applied in the running velocity that meter-gage motor car bogie can improve greatly bogie truck.But due to the limited space between meter gauge bogie two wheel, even only install actuating device insufficient space, so original, by brake disc, the scheme be arranged between two wheels no longer has feasibility.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of meter-gage motor car bogie installing shaft mounted type brake disc and takes turns composition, and the highest running speed of bogie truck is increased to 160km/h.
For solving the problems of the technologies described above, the invention provides a kind of meter-gage reel braking motor car bogie wheel to composition, primarily of wheel, axletree, axle box composition, brake disc and actuating device composition, it is characterized in that:
1. axle box consists of penetration type structure, and journal box front cover and bonnet are all run through by axletree, and coordinating between journal box front cover, bonnet and interval cylinder, dust slinger all adopts labyrinth seal structure, a case protecgulum, all adopts contact-type seal between bonnet and axle box;
2. axletree extends through axle box composition, and brake disc is arranged on the axletree that passes outside axle box, and the pattern adopting key or spline structure to coordinate is installed, and pushes down with bolts at axle end and gland;
3. journal box front cover is installed antiskid velocity sensor, integrated installation earth system on gear case.
Advantage of the present invention is: the first, by adopt penetration type axle box composition shaft mounted type brake disc is arranged on outside axle box, solve the problem of brakeless dish installing space between two wheels, make Axle Disc Brake Equipment meter-gage motor car wheel on be mounted for possibility.The second, the application due to Axle Disc Brake Equipment substantially increases braking heat absorption capacity limit value, improves the highest running speed of vehicle, can ensure the running velocity requirement of 160km/h.3rd, brake disc adopts the pattern of key or spline fitted to be arranged on axletree, can solve the problem of transmission of lock torque on the one hand, also makes the assembly and disassembly of brake disc simpler on the other hand, facilitates maintenance and the replacing of axle box bearing.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
detailed description of the invention:
Reference accompanying drawing 1,1 is wheel, and 2 is axletree, 3 is brake disc, and 4 is axle box, and 5 is axle box bearing, 6 is journal box rear cover, and 7 is journal box front cover, and 8 is interval cylinder, 9 is dust slinger, and 10 is axle head gland, and 11 is bolts at axle end, 12 is actuating device, and 13 for being integrated in the earth system on gear case, and 14 for being integrated in the antiskid velocity sensor gear on the cylinder of interval, 15 is antiskid velocity sensor, and 16 is O type circle.Wherein, actuating device is arranged between two wheels, and the whole driven device in the space between two wheels occupies, and does not install the space of brake disc.In order to install shaft mounted type brake disc, axletree is extended through axle box composition (comprising axle box bearing, axle box, journal box front cover, journal box rear cover etc.), the keyway coordinated with brake disc or spline is processed in axletree end, brake disc is arranged on axletree, and with bolts at axle end and gland, brake disc, interval cylinder and axle box bearing is firmly compressed.And axle box bearing adopts interference fit to be fitted on axletree, between journal box front cover and interval cylinder, be designed to labyrinth seal structure, integrated slip prevention speed sensor gear gone back by interval cylinder simultaneously; O type circle is adopted to seal between journal box front cover and axle box; Labyrinth packing is adopted between journal box rear cover and dust slinger; These structures can ensure the sealing that axle box forms well.Owing to adopting key or spline fitted between brake disc and axletree, load maximum between brake disc and axletree is able to be transmitted by key or spline fitted, ensure that the reliability of dynamic changes process.Meanwhile, with original conventional axletree with adopt compared with press-fit between brake disc, the assembly and disassembly of key or spline fitted are all more convenient, for the examine and replace of brake disc and axle box bearing provides conveniently.
