Abstract

The invention discloses a steering hydraulic pump suitable for heavy-duty vehicles in emergency working conditions, which can make the steering hydraulic pump operate when the vehicle, especially the heavy-duty vehicle encounters an emergency working condition and the engine stops running, and emergency steering is required. Automatically maintain an effective steering boosting effect within a certain period of time, so that the driver can immediately perform an effective steering operation after the engine stops running; In the related art, the steering hydraulic pump cannot perform steering boost immediately after the engine stops, which leads to the technical problem that the safety of the heavy-duty vehicle under emergency conditions cannot be guaranteed, so as to effectively ensure the safety of the heavy-duty vehicles under emergency conditions. The effect of vehicle and personnel safety.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a steering hydraulic pump suitable for emergency working conditions of heavy vehicles. Background technique [0002] When the vehicle is running, in order to ensure that the driver performs steering control, the steering control mechanism can provide sufficient torque to the steering transmission mechanism, so a steering booster device is often installed between the steering control mechanism and the steering transmission mechanism, such as steering hydraulic pump, etc. In the actual working process, the steering hydraulic pump in the related art can convert the mechanical energy output by the vehicle engine into the pressure energy inside the steering hydraulic pump, and then apply hydraulic pressure to the steering transmission mechanism during the steering process of the driver to perform Turn to afterburner. [0003] The steering hydraulic pump in the above-mentioned rela...
