摘要： An engine compartment cover for a work machine includes left and right-hand side covers for covering the sides of an engine, and a hood for covering the top of the engine. The engine compartment cover serves to enclose the engine and demarcate an engine compartment and is capable of suppressing the noise at the operator's ear level caused by the engine operating noise passing through the engine compartment cover as far as possible, whereby the level of quietness in the operator cab can be improved. In the engine compartment cover for a work machine, the hood has a box-type structure including an exterior top plate, side plates surrounding the whole perimeter of the exterior top plate, and a bottom plate opposed to the exterior top plate, and air inlet holes are provided in the side plates only, whilst an air outlet hole is provided in the bottom plate only, in such a manner that external air is drawn into the interior of the hood via the air inlet holes and air is introduced into the engine compartment via the air outlet hole.

摘要： A clutch and brake control system for a tracklaying construction vehicle is disclosed, which comprises a turning operation system and a driving brake operation system. The turning operation system is operative to carry out slow turning steering and quick turning steering of the vehicle by controlling clutches provided for right and left crawler belts for the purpose of transmitting driving force to the crawler belts and controlling brakes provided for right and left crawler belts for the purpose of stopping the rotation of the crawler belts. The driving brake operation system is operative to stop the vehicle by actuating only both of the brakes. To simplify a control linkage extending from an operating section to valves thereby reducing looseness and deflection to improve operability, the brakes are each composed of (i) a steering brake valve for carrying out brake releasing or brake actuation by delivering or reducing fluid pressure with respect to a brake hydraulic circuit according to the operation of the turning operation system and (ii) a driving brake valve for carrying out brake actuation by reducing fluid pressure in the brake hydraulic circuit according to the operation of the driving brake operation system.
摘要翻译：公开了一种用于履带式施工车辆的离合器和制动控制系统，其包括转向操作系统和驱动制动操作系统。转向操作系统用于通过控制左右履带的离合器来执行车辆的慢转向转向和快速转向转向，用于将驱动力传递到履带并控制用于左右履带的制动器为了停止履带的旋转。驱动制动器操作系统通过仅致动两个制动器来停止车辆。为了简化从操作部分延伸到阀门的控制连杆，从而减少松动和挠度以提高可操作性，制动器分别由（i）转向制动阀组成，该转向制动阀用于通过输送或降低流体压力来执行制动释放或制动器致动根据转向操作系统的操作到制动液压回路，以及（ii）驱动制动阀，用于通过根据驱动制动器操作系统的操作减少制动液压回路中的流体压力来执行制动器致动。
