Abstract
A dragging steering truck for low-floor lightrail vehicles comprises a framework (1), a hydraulic shock absorber (2), a tow rod (3), an axis bridge type independent wheel (4), a basic brake rigging (5), a primary suspension (6), a secondary suspension (7), and the like. The utility model is characterized in that the axis bridge type independent wheel (4) comprises a taper-roller bearing (10) and a taper-roller bearing (9) which are disposed back-to-back, a brake spindle (11) for fixing a disk brake disk and an end cover are integrated into one body and are fixedly connected with each other via bolts and a wheel center, a cartwheel (8) adopts an elastic wheel with conical rubber inserts, a carriage axle (an axis bridge (12)) is concave V-shaped, cartwheels which can do relative movement are arranged on stub axles positioned on two ends of the carriage axle and form a wheel assembly, shapes of treads are worn profile treads and are formed by lines R1, R2, R3, R4 and R5 which have gradients of 1:45, the value of R1 is 400-540mm, the value of R2 is 110-115mm, the value of R3 is 10-20mm, and the value of R4 is 18-22mm.
Description
Belong to the urban rail transit technology field
At present, urban track traffic is in the ascendant, and the light rail transit line is all prepared to build in many big and medium-sized cities, the low floor technology in Europe, the North America is popular, is the trend in epoch.Domestic still in trial-production, because light rail circuit and main line, the different light rail cars of subway are born the city passenger transportation, the transport solution congested problem again at city ride.So the light rail car drags bogie truck and locomotive.The requirement of vehicles such as passenger vehicle, lorry, subway car all has the difference of genus, and the version of bogie truck, parameter have determined the riding quality of light rail vehicle, and dragging bogie truck is decision light rail vehicle key of success.
The purpose of this utility model is to design a kind of High Performance, small-sized light weight, high reliability to maintain easily the bogie truck that drags of suitable light rail car.
The utility model is finished with following mode, and low-floor light rail vehicle drags bogie truck (seeing Fig. 1, Fig. 2, Fig. 3) and comprises framework (1), hydraulic shock absorber (2), draw bar (3), axle bridge-type independent wheel (4), foundation brake (5), single stage suspension (6), secondary suspension compositions such as (7).Axle bridge-type independent wheel (4) (see figure 4), bridge (a 12) middle part is integral for forging and with the spring abutment and the bearings mounted semiaxis that adapt to V spring installation needs because intensity needs.Bearing assembly on the axle bridge is arranged by tapered roller bearing (10) and tapered roller bearing (9) dos-.The brake axle of fixation disc type brake disc (11) is an one with end cap, and is fixed with bolt and core wheel.Wheel still adopts the elastic wheel (8) of cone rubber inserts.The obstacle that reduces floor level is not vehicle but axletree.Therefore, low floor vehicle can not drag bogie truck with routine axletree (axle bridge (12)) is done down spill to reduce the centre gangway floor level.Wheel composition wheel is right in relative rotation for dress on the minor axis at axletree (axle bridge (12)) two ends.During operation, axletree does not change, and wheel is transferred and wheel can the different rotating speeds operation.Its worn profile tread of tread profile (see figure 5) is combined by 1: 45 gradient straight line, R1, R2, R3, R4, R5, the value of R1 is that the value of 400～540mm, R2 is that the value of 110～150mm, R3 is that the value of 10～20mm, R4 is that the value of 18～22mm, R5 is 9～11mm, and the value of R6 is 18～22mm.
