Abstract

The invention discloses an electromagnetic valve for controlling the traveling direction. The electromagnetic valve for controlling the traveling direction comprises an electromagnetic valve body, an electromagnetic valve element, an electromagnetic reset spring, an electromagnetic valve control part, an electromagnetic cavity inlet, an electromagnetic valve outlet and an electromagnetic valve oil return cavity. When the electromagnetic valve control part controls the electromagnetic valve element to reciprocate between a working position and a restoration position, a combined valve oil outlet cavity A or a combined valve oil outlet cavity B is opened or closed accordingly, and the combined valve oil outlet cavity A or the combined valve oil outlet cavity B correspondingly drives an associated traveling mechanism to advance or retreat. According to the electromagnetic valve for controlling the traveling direction, in traveling acceleration and deceleration states and in other states, an operator just needs to tread on a combined valve control part to increase the opening degree of an accelerator, more oil is supplied by a hydraulic traveling system, the vehicle speed is higher, and a vehicle can advance or retreat or be in a neutral-gear state by powering on or powering off the electromagnetic valve for controlling the traveling direction at the same time; the control mode which is more user-friendly can adapt to driving habits of a driver and the operator, and great convenience is brought; and the electromagnetic valve is particularly suitable for operation under complex road conditions and severe working environments, and the comfort and safety in traveling and working states and in other states can be further improved.

Description

technical field [0001] The priority document of this patent application is as follows: the priority number of the Chinese invention patent is CN201610796480.6, the priority date is August 31, 2016, and the name is "traveling direction control solenoid valve". The invention relates to a pedal of engineering vehicles such as wheeled excavators, in particular to a walking direction control solenoid valve. Background technique [0002] The current engineering vehicles such as wheeled excavators, in the driving state such as driving, parking, acceleration, deceleration, etc., the driver and the operator need to make corresponding operations in time and control the size of the accelerator to adapt to the changes in the driving state. Also need to do corresponding operation to hang gear, adjust steering wheel etc., not only inconvenient to operate, and operability also needs to be further improved. [0003] In the case of complicated road conditions and bad working environment, th...
