For the problems referred to above of the trailer axle that solves prior art, the utility model proposes a kind of disc type trailer axle.
The trailer axle of the utility model comprises: bridge tube, air chamber, brake assembly; Said brake assembly is a plate disc brake, is arranged at the end of said bridge tube, and said plate disc brake is driven by said air chamber, and air chamber is fixed on the said drg.
Preferably, said bridge tube is the overall thermal extrusion forming, and cross section, bridge tube stage casing is square.
Preferably, the sectional dimension of said bridge tube is: 150mm * 150mm * 14mm.
Preferably, the wheelspan of said trailer axle is 1800mm～1860mm.
Preferably, the wheelspan of said trailer axle is 1830mm.
Preferably, be respectively equipped with a bracket plate at the bridge tube two ends, the width between centers of bracket plate is 940mm～960mm.
Preferably, the width between centers of said bracket plate is 953mm.
Preferably, the specification of said plate disc brake is φ 430 * 45, output maximum braking moment 36000N.m.
The trailer axle of the utility model wheel limit compact conformation, deceleration and stopping performance is good, heat stability is high, good heat dissipation, be easy to maintenance.
Description of drawings
From purport and the preferred embodiment of use and the following description of accompanying drawing to explanation the utility model, above and other purpose, characteristics and the advantage of the utility model will be conspicuous, in the accompanying drawings:
Fig. 1 is the scheme drawing of the trailer axle of the utility model;
Fig. 2 is the section drawing of bridge tube of the trailer axle of the utility model.
The specific embodiment
Below, specify in conjunction with the trailer axle of 1,2 pairs of the utility model of Figure of description.
As shown in Figure 1, the trailer axle of the utility model comprises bridge tube 1, air chamber 3, brake assembly 2; Said brake assembly 2 is a plate disc brake, is arranged at the end of said bridge tube 1, and said plate disc brake is driven by said air chamber 3, and air chamber 3 is fixed on the said brake assembly 2.Said bridge tube 1 is the overall thermal extrusion forming, and cross section, bridge tube stage casing is square, and the sectional dimension of said bridge tube is: 150mm * 150mm * 14mm, and as shown in Figure 2.
Preferably, the wheelspan of said trailer axle is 1800mm～1860mm.
Preferably, the wheelspan of said trailer axle is 1830mm.
Be respectively equipped with a bracket plate 4 at the bridge tube two ends, the width between centers of bracket plate is 940mm～960mm, and preferably, the width between centers of said bracket plate is 953mm.
Preferably, the specification of said plate disc brake is φ 430 * 45, output maximum braking moment 36000N.m.
As above the trailer axle of structure wheel limit compact conformation, deceleration and stopping performance is good, heat stability is high, good heat dissipation, be easy to maintenance.
Although illustrated and described the preferred embodiments of the present invention, it is contemplated that, those skilled in the art can be in the spirit of the utility model and scope design to the various modifications of the utility model.
