The explanation of practical embodiment
Different figure is the different views of same structure and possibility modification.For clarity sake, used numbering is quite few, and generally speaking, numbering mainly is used among the figure that occurs reference part first.
Track carrier loader shown in Figure 1 comprises and is rotationally connected with holding vehicle frame 1, be connected in two side bracket 2 and two wheel assemblies 3 that hold vehicle frame 1 by the spring (not shown) on the track carrier loader vehicle body (not shown), each wheel assembly forms axle journal, so that can rotate on side bracket 2.Each wheel assembly has two wheels 4.
The so-called bogie brake that is used for this dolly, as known in this technology, have two horizontal brake beams 5, this beam is hung between two wheel assemblies 3, is configured to pressurize with being separated and makes the tyre surface that the brake shoe 6 that is positioned at the brake beam end can brake engaged wheel 4.
Each brake shoe 6 is through can abrasion after the braking force effect repeatedly and must change, so the device that this brake shoe utilization below will illustrate releasably is fixed on the brake shoe seat 7.Each brake shoe seat 7 has suspension rod 8, and this suspension rod hangs on the suspended portion of holding vehicle frame 1 rotationally, makes brake beam hang on the spring load part.Thereby utilize conventional friction gear 10 can make brake shoe seat 7 and brake beam 5 be fixed on the suitable position of hanging with respect to suspension rod 8.Horizontal or the sideway movement of 10 pairs of brake beams 5 of these friction gears also plays a part elasticity and damping arrangement.
Can find out that from Fig. 8～10 brake unit 11 can be standard block (Fig. 8), have the unit (Fig. 9) of mechanical parking brake rod 13, or have the unit (Figure 10) of spring stop lock.
