1.改进原因目前大功率推土机制动踏板的主要结构形式为地板下伸出式,如图1所示。地板下伸出式制动踏板可整体安装到地板支架上,具有拆卸方便的优点,但同时具有以下2个缺点:一是由于制动踏板在驾驶室地板下面,给调节定位螺栓和加注润滑油带来不便;二是需在驾驶室地板上开出长槽,由此导致驾驶室容易遭受噪声和粉尘污染。为此,我们决定对大功率推土机制动踏板进行结构改进。
1. Improve the reasons At present, the main structure of the high-power bulldozer brake pedal out of the floor, as shown in Figure 1. The under-floor reach-out brake pedal can be installed on the floor support as a whole, which has the advantages of convenient disassembly, but has the following two disadvantages at the same time. First, as the brake pedal is under the floor of the driver’s cab, the adjusting bolt and the filling lubrication Oil inconvenience; the second is to open a long groove on the cab floor, resulting in cab susceptible to noise and dust pollution. To this end, we have decided to make structural improvements to the high-power bulldozer brake pedal.
