Abstract
The utility model provides a compensating axle suspension for a connection shaft tubular truck, which is composed of a left bracket and a right bracket, a left axle shaft and a right axle shaft, a connection shaft tube and a balance bearing hub which are connected to each other. The connection shaft tube is an integral hollow tube unit; the part of the connection shaft tube between the left bracket and the right bracket is a hollow straight tube; the connection shaft tube is connected to a large hole at the lower end of brackets of a left balance shaft and a right balance shaft through bolts. The compensating axle suspension divides the original integral forging communication shaft into the two axle shafts and one connecting shaft tube, thereby improving the processing manufacturability of components, ensuring the processing accuracy, canceling the forging communication shaft, lowering the cost of blank components and solving the concentrated transitional stress of a forging piece R. Meantime, the compensating axle suspension adopts a segmental structure, thereby facilitating the maintenance and the exchange and lowering the maintenance cost.
Description
Technical field
The utility model relates to the bogie balance suspension.
Background technology
Existing bogie balance suspension structure is: be connected with left and right support by connection shaft, connection shaft plays the effect that connects support and bear car load simultaneously, and because of the complete vehicle structure restriction, connection shaft need adopt forging manufacturing processing, the cost height, easily there is the stress concentration defective in the forging curve simultaneously.
Summary of the invention
For the connection shaft that solves existing balance suspension adopts forging manufacturing processing, the cost height, easily there are problems such as stress concentration defective in the R transition, the utility model proposes a kind of adapter shaft tubular type bogie balance suspension that improves structure.
For this reason, the technical solution of the utility model is: adapter shaft tubular type bogie balance suspension, by left and right support, left and right half, connection central siphon, equalizer bearing hub connect and compose, it is characterized in that: described connection central siphon is whole hollow pipe fitting, connecting the position of central siphon between left and right support is hollow straight tube, and the macropore that connects central siphon and left and right balance shaft support lower end passes through bolted connection.
The beneficial effects of the utility model are described below:
The utility model is decomposed into former solid forging connection shaft two semiaxis and is connected central siphon with one, has improved the fabrication properties of part, is easy to the assurance of working accuracy; Cancel the forging connection shaft, reduced the part blank cost, solved the problem that forging R unfair stress is concentrated.Adopt segmentation structure simultaneously, made things convenient for maintain and replace, reduced maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Adapter shaft tubular type bogie balance suspension is is as shown in Figure 1 connected and composed by left socle 2, right support 4, left half axle 7, right axle shaft 8, connection central siphon 3, left equalizer bearing hub 1, right equalizer bearing hub 5; Described connection central siphon 3 is whole hollow pipe fittings, and connecting the position of central siphon 3 between left and right support 2,4 is hollow straight tube, connects central siphon 3 and is connected by bolt 6 with the macropore of left and right support 2,4 lower ends.
Claims (1)
1, adapter shaft tubular type bogie balance suspension, by left and right support, left and right half, connection central siphon, equalizer bearing hub connect and compose, it is characterized in that: described connection central siphon is whole hollow pipe fitting, connecting the position of central siphon between left and right support is hollow straight tube, and the macropore that connects central siphon and left and right balance shaft support lower end passes through bolted connection.
