Technical Field
The utility model relates to a two-way driving car turns to centering system belongs to engineering machine tool power steering system technical field.
Background
In the engineering construction process, the road section with narrow space or narrow road, long vehicle and difficult turning is frequently encountered. As a vehicle with a bidirectional driving function, how to realize the steering interlocking of a front axle and the centering of a rear axle is the key, and if the steering in two directions cannot be interlocked, the vehicle cannot normally walk. If the rear axle can not be centered, the vehicle can not go straight, and the driving safety is influenced.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem, the utility model provides a can realize two-way steering centering system solves the problem of the relatively poor unable tune of road condition or tune difficulty, and this system has that economic nature is good, maintain the characteristics with low costs.
The utility model discloses a two-way driving car steering centering system, which is characterized in that the system comprises a hydraulic oil tank, a pump, a front steering electromagnetic valve, a steering gear, a steering oil cylinder, an interlocking switch, a sensor, an indicator light, a buzzer, a hydraulic lock and a rear steering electromagnetic valve;
The steering gear is installed on a cab, the steering oil cylinder is installed on a front steering axle and a rear steering axle, the hydraulic lock is installed on the steering oil cylinder, the front steering electromagnetic valve, the rear steering electromagnetic valve and the hydraulic oil tank are installed on a frame, the pump is installed on a power source of a vehicle, the interlocking switch, the indicator light and the buzzer are installed on an instrument desk of the cab, and the pump, the steering gear, the hydraulic lock, the front steering electromagnetic valve, the rear steering electromagnetic valve and the hydraulic oil tank are connected through hoses and connectors.
Further, the steering of the driving in two directions is interlocked by the front steering solenoid valve and the rear steering solenoid valve, that is, when there is steering in one direction, the steering in the other direction is locked.
Furthermore, the steering oil cylinder is locked by a hydraulic lock when the steering oil cylinder does not steer, so that the steering oil cylinder is used as a thrust rod, and the steering oil cylinder is ensured not to swing under the condition of bad roads when the steering oil cylinder is used as a rear axle, so that the driving is not influenced.
Further, when the rear axle is not centered, the rear axle is fed back to the cab through a sensor arranged on the axle, and the buzzer gives an alarm to remind a driver.
the working principle of the utility model is as follows:
The whole hydraulic system is provided with pressure oil by a power source driving a pump.
In this description, it is assumed that the cab 1 is in the driving direction, the vehicle enters the cab 1, the cab 1 is pressed to select to run, the pressure oil is switched to the cab 1 through the front steering solenoid valve, and the pressure oil is disconnected from the cab 2 through the rear steering solenoid valve. Meanwhile, the electric system judges whether the rear axle is centered or not through the sensor, if the rear axle is centered, the indicating lamp is not on, and the buzzer does not sound. The rear axle steering oil cylinder does not steer and is locked by the hydraulic lock, so that the steering oil cylinder is used as a thrust rod, and the steering oil cylinder does not swing under the condition of poor road when used as a rear axle, so as to avoid influencing driving.
