The invention aims to provide the wheel type engineering equipment, so that a vehicle has two functions of brake out-of-gear and brake non-out-of-gear at the same time. The wheel type engineering equipment comprises a vehicle body, a power system, a hydraulic braking system and a hydraulic speed change system are arranged on the vehicle body, the hydraulic braking system comprises a braking oil tank and a braking oil way, and the braking oil way is connected with a braking pump, a prefill valve and two braking branches located on the downstream of the prefill valve. At least one of the two brake branches is provided with a brake signal sensor, the brake signal sensor is electrically connected with the controller and feeds back a brake signal to the controller, the oil conveying pipeline is connected with an electric control valve in series, the electric control valve is electrically connected with the controller, and the oil conveying pipeline is connected or disconnected under the control of the controller; the hydraulic braking system further comprises a mode selection switch; the mode selection switch is connected with the braking signal sensor or the controller, and when the mode selection switch is in a first state, braking is out of gear; when the mode selection switch is in the second state, the brake is not out of gear.
本发明的目的在于提供一种轮式工程装备,以使车辆同时具有刹车脱档和刹车不脱档两种功能。轮式工程装备包括车体,在车体上配置有动力系统、液压制动系统和液压变速系统,液压制动系统包括制动油箱以及制动油路,制动油路上连接有制动泵、充液阀以及处于充液阀下游的两制动支路,两制动支路的至少一个上设有制动信号传感器,制动信号传感器与控制器电连接并向控制器反馈制动信号,输油管路上串接有电控阀,电控阀与控制器电连接且在控制器的控制下通断输油管路,液压制动系统还包括模式选择开关,模式选择开关与制动信号传感器或控制器连接,模式选择开关处于第一状态时,刹车脱档;模式选择开关处于第二状态时,刹车不脱档。
