Problems solved by technology

[0005] In addition, after the vehicle has been used for a long time, the fastening bolts on which the rubber nodes are installed are prone to loosening and rotation problems, thus changing the vertical clearance between the linear motor and the wheel rail
[0006] When the fastening bolts are loosened or rotated, the radial shear force generated between the fastening bolts and the mounting seat due to the vertical weight of the linear motor may easily lead to the breakage of the fastening bolts, thereby affecting the suspension of the linear motor. safety and reliability

Embodiment 1

[0058] Example 1, such as figure 1 and figure 2 As shown, the rail vehicle linear motor bogie mainly includes two sets of wheels 1, and the axle 11 of each set of wheels 1 is carried on two symmetrically arranged axle boxes 2 through bearings; a frame 3, a frame 3 The axle box body 2 is supported by the primary suspension device, and the frame 3 is supported on the vehicle body (not shown in the figure) by the secondary suspension device (not shown in the figure);

[0059] On the axle 11 of each group of wheels 1, two symmetrically arranged support boxes 5 are installed through bearings,

[0060] Several vertical suspenders 7 suspend and connect the linear motor 4 to each transverse suspension beam 6;

[0061] On the same axle 11, two supporting boxes 5 are respectively arranged on the inner side of the wheel set 1, and two axle boxes 2 are respectively arranged on the outer side of the wheel set 1;

[0062] Between each axle shaft 11 and its adjacent frame 3 ends, a balan...

Abstract

The invention provides a device and method for suspension and height adjustment of a linear motor of a railway vehicle. Adjusting shims are used to vertically adjust an anchor point at the end part of a horizontal suspension beam so as to accurately control and adjust the vertical gap of the linear motor relative to a railway sensory board of the linear motor, thus being beneficial to stably and efficiently running the vehicle. The suspension device comprises a support box which is mounted on an inboard shaft of a wheel set by a bearing and used for suspending a horizontal suspension beam of the linear motor; and the horizontal suspension beam end part is supported on the support box elastically by rubber nodes. The top of the support box is provided with a pair of convex mounting seats; a group of fastening and locking devices is used for vertically mounting the rubber nodes at two ends of the horizontal suspension beam on the mounting seats respectively; the adjusting shims are arranged between mounting poles of the rubber nodes and the mounting seats of the support box; fastening bolts are used to vertically mount the rubber nodes on the mounting seats of the support box; and the thicknesses of the adjusting shims are combined to adjust the vertical suspension and vertical height of the linear motor.

Description

technical field [0001] The invention relates to a suspension and height adjustment device and method for a rail vehicle linear motor, belonging to the field of mechanical manufacturing. Background technique [0002] With the rapid increase of the speed of domestic trunk railways and the rapid development of urban rail transit, linear motor radial bogies are gradually gaining overall technological Leading edge and market recognition. [0003] In the existing technical solution, the linear motor is installed under the support box at both ends of the axle through a pair of transverse suspension beams. In order to ensure that the transverse suspension beam can perform limited axis rotation around its installation point, and to deal with the small swing of the linear motor relative to the bogie during vehicle driving, rubber nodes are usually used to elastically carry the transverse suspension beam on the support box. [0004] For this type of linear motor suspension connection...
