Abstract
The utility model discloses an electro-hydraulic steering system for a coach, which comprises a hydraulic power steering gear and is characterized by further comprising a vehicle speed sensor, a microprocessor, an electronic control device and an electronic control bypass valve. The target value of the opening of the bypass valve is figured out by the microprocessor according to vehicle speed signals sent by the vehicle speed sensor and drives the electronic control device on the bypass valve to enable the opening of the bypass valve to reach preset target values. The electro-hydraulic steering system for the coach collects the vehicle speed signals through an electronic control unit and controls flow of the steering system so as to achieve the purpose of changing input torque, obtain suitable input-output properties, and improve portability pivot steering and low speed and stability of running at high speed.
Description
Technical field
The utility model relates to a kind of passenger vehicle electricity consumption liquid steering swivel system.
Background technology
Existing passenger vehicle steering swivel system all is the mechanical-hydraulic power steering system, the defective that exists is: the flow control by automobile steering device is just realized according to engine speed change by steering pump, and often have a lot of influence factors between the rotating speed of driving engine and the actual vehicle speed, and the variation between them neither be linear.But a principal parameter that influences the passenger vehicle steering swivel system is the speed of a motor vehicle, is not engine speed.
The utility model content
The utility model purpose is: provide a kind of by the sensor sensing vehicle speed signal, come control policy according to vehicle speed signal, calculate the expected value of bypass disc aperture, and the electrical controller on the driving bypass disc makes the bypass disc aperture reach predetermined target value, the hydraulic booster characteristic of bypass control valve (BCV) decision main valve, thereby the passenger vehicle electricity consumption liquid steering swivel system of the input torque on the decision bearing circle.
The technical solution of the utility model is: a kind of passenger vehicle electricity consumption liquid steering swivel system, comprise hydraulic power steering device, it is characterized in that, also comprise car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that described microprocessor sends according to described car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.
Further, described microprocessor is the ECU of passenger vehicle.
The utility model has the advantages that:
1. native system is simple in structure, and is safe and reliable, when the electric system et out of order, can guarantee the input-output characteristic of the common hydraulic power steering device of system held.
Guaranteed the portability that automobile turns to when the low speed driving and stability when running at high speed based on the cornering properties of speed responsive, in addition, guarantee that under any speed of a motor vehicle the oil pressure of work and flow all can reach maxim, can resist unexpected automatic steering, make to turn to accurately, safer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a passenger vehicle electricity consumption liquid steering swivel system scheme drawing of the present utility model.
The specific embodiment
Embodiment: passenger vehicle electricity consumption liquid steering swivel system as shown in Figure 1 comprises hydraulic power steering device (HPS), car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that microprocessor sends according to car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.In the present embodiment, microprocessor adopts the ECU on the car.During mode of operation, by the sensor sensing vehicle speed signal, vehicle speed signal is sent to ECU and handles, calculate the expected value of bypass disc aperture, and the electrical controller on the driving bypass disc makes the bypass disc aperture reach predetermined target value, the hydraulic booster characteristic of bypass control valve (BCV) decision main valve, thereby the input torque on the decision bearing circle.Passenger vehicle electricity consumption liquid steering swivel system of the present utility model is simple in structure, has increased ECU (Electrical Control Unit) and automatically controlled bypass disc on former mechanical-hydraulic power steering system.Passenger vehicle electricity consumption liquid steering swivel system of the present utility model is crossed ECU (Electrical Control Unit) and is gathered vehicle speed signal, and the flow of steering swivel system controlled, thereby reach the purpose that changes input torque, obtain suitable input-output characteristic, the stability that improves automobile pivot stud and low-tach portability and run at high speed.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
1. passenger vehicle electricity consumption liquid steering swivel system, comprise hydraulic power steering device, it is characterized in that, also comprise car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that described microprocessor sends according to described car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.
2. passenger vehicle electricity consumption liquid steering swivel system according to claim 1 is characterized in that described microprocessor is the ECU of passenger vehicle.
