Abstract

The utility model discloses a hanging linear motor bogie for an independent wheel pair. An independent wheel pair structure is adopted, and the independent wheel pair is fixed on two ends of a vehicle bridge by bearings. A linear motor is hung on the side part of the vehicle bridge by a hanger rod. The unsprung mass is reduced by removing the axle box body structure, thereby achieving that the influence on the wheel pair due to the impact of the rail is reduced, reducing the variation range of the air gap between the linear motor and a sensing plate, and improving the energy utilization rate. The bogie mainly comprises a frame, a front independent wheel pair, and a rear independent wheel pair, wherein the independent wheel pairs are fixedly connected to two ends of the vehicle bridge through bearings; the linear motor is hung on the side part of the vehicle bridge through the vertical hanger rod; the vehicle bridge is connected with the frame through a longitudinal traction draw rod; and the linear motor is connected with the frame through a longitudinal draw rod and a transverse draw rod respectively. As the characteristics of the proposal, the adopted independent wheel does not need to be provided with the axle box body, and the linear motor carries out hanging through the hanger rod so as to directly bear the uneven stimulation from the rail on the road surface.

Description

Independent wheel pair suspension linear motor bogie

Technical Field

The utility model relates to a bogie for rail vehicle, specifically the axle of independent wheel pair hangs linear electric motor specifically belongs to the machine-building field.

Background

The bogie is applied to the bogies of railway trains, subways and light rail traffic vehicles, and the rigid framework structure is generally adopted at present. The axle box body is arranged on the wheel set to realize installation and suspension of the linear motor, the mass of a part below a series of springs is large in the structure, and the wheel set is highly influenced by the impact of a lower rail. Moreover, the air gap between the linear motor and the induction plate has a large variation range, so that the energy consumption of the linear motor is high on the premise of a certain traction output.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an independent wheel pair hangs linear electric motor bogie to solve above-mentioned problem and defect. The independent wheel set structure is adopted, the independent wheel sets are fixed at two ends of the axle through the bearings, the linear motor hangs the side portion of the axle through the hanging rod, and unsprung mass is reduced by canceling the structure of the axle box body, so that the influence of track impact on the wheel sets is reduced, the air gap variation range between the linear motor and the induction plate is reduced, and the energy utilization rate is improved.

In order to achieve the design purpose, the independent wheel pair suspension linear motor bogie mainly has the following structure:

comprises a framework, a front independent wheel pair and a rear independent wheel pair, wherein,

the independent wheel pairs are fixedly connected to two ends of the axle through bearings, the linear motors hang the side portions of the axle through vertical suspenders, the axle is connected with the framework through a series of longitudinal traction pull rods, and the linear motors are connected with the framework through the longitudinal pull rods and the transverse pull rods respectively.

According to the technical scheme, the adopted independent wheel does not need to be provided with the axle box body, and the linear motor is hung through the hanging rod and directly bears the excitation of the irregularity of the track from the road surface.

Hang linear electric motor with prior art and compare on axle box, the utility model discloses cancel axle box structure to reduce unsprung mass effectively, the wheel pair receives the influence of track impact to reduce, and the air gap between linear electric motor and the tablet can reduce moreover.

In order to improve the performance of the axle suspension linear motor and adjust the vertical connection rigidity, the axle is provided with a bridge with the middle part protruding upwards, the side part of the axle is provided with a suspension mounting seat for suspending the linear motor, and a vertical suspender is mounted on the suspension mounting seat through a ball joint bearing and a height adjusting nut.

In order to improve the vertical vibration reduction effect, a vertical rubber stacking spring is directly arranged on the axle.

In order to ensure the air gap variation range between the linear motor and the induction plate, 3 vertical suspenders are adopted to suspend the linear motor in a vibration plane formed by suspension points, and suspension mounting seats are respectively arranged on opposite planes at the inner sides of a front axle and a rear axle.

As described above, the bogie for suspending the linear motor by the independent wheel set has the advantages that the independent wheel set is adopted, the linear motor is suspended at the side part of the axle, and the structure of the axle box body is eliminated to reduce the unsprung mass, so that the influence of the impact of the track on the wheel set can be effectively reduced, the air gap variation range between the linear motor and the induction plate is reduced, and the power output of the linear motor is improved.
