Background technology
The action of braking and starting to walk will appear in double dynamical passenger vehicle continually in the cruising process; This just means that also hydraulic control pump switches the modulated pressure element continually and works; To realize the accumulation of energy and the exoergic of hydraulic power device; And existing technology does not still have the constant voltage speed regulation device, this just make passenger vehicle can occur going not steady, and the too high generation that causes hydraulic part early failure or the like phenomenon of oil temperature.The application of the hydraulic control pump of double dynamical passenger vehicle band constant voltage speed regulation device makes these problems obtain solving effectively.
Summary of the invention
The present invention is directed to the deficiency and the defective of prior art, a kind of hydraulic control pump of double dynamical passenger vehicle band constant voltage speed regulation device is provided, improved the reliability of service of hydraulic hybrid device.The present invention mainly comprises: braking back pressure control device, pressure store controller, pressure sensor, energy storage, HM Hydraulic Motor governor, constant pressure device, Hydraulic Pump, HM Hydraulic Motor, pressurization thermostatic type fuel tank etc.The invention of band constant voltage speed governing hydraulic press is with the different of prior art: Hydraulic Pump, HM Hydraulic Motor work alone, and constant voltage speed governing, adjustable braking back pressure have improved output torque, have stablized the vehicle start rotating speed.Through the central signal controller, when the braking accumulation of energy, the Hydraulic Pump clutch engagement; Hydraulic Pump, can be stored into hydraulic pressure in the energy storage, when energy storage pressure is enough through the transmission shaft driven rotary by vehicle inertia power; Braking back pressure device can be opened, and at this moment, gently touches on the brake; No energy storage effect has only oil pump loop back pressure brake action.When the light step on the accelerator of vehicle starts; Through the central signal controller; The HM Hydraulic Motor power-transfer clutch combines, and the high pressure oil in the energy storage discharges to HM Hydraulic Motor through pressure store controller and constant pressure device, drives the HM Hydraulic Motor rotation; Can convert hydraulic pressure to mechanical energy, drive vehicle through transmission shaft and advance.
Description of drawings
Like Fig. 1 is apparatus of the present invention scheme drawing.The specific embodiment is as shown in Figure 1:
The hydraulic control pump of double dynamical passenger vehicle band constant voltage speed regulation device mainly comprises: braking back pressure control device 1; Pressure store controller 2; Pressure sensor 3; Energy storage 4; HM Hydraulic Motor governor 5; Constant pressure device 6; Hydraulic Pump 7; HM Hydraulic Motor 8; Pressurization thermostatic type fuel tank 9; The double dynamical transmission gearbox 10 of stand alone type automatic switchover; Friction clutch shift fork 11; Cylinder 12; Cylinder controller 13; Inserted valve C1-C5.
1. braking accumulation of energy: in the vehicle ' process maybe when entering the station; Gently step on brake pedal, speed-slackening signal is transferred to the central signal controller, and this moment is when energy storage pressure during less than setting pressure; The central signal controller sends instruction and gives cylinder controller 13 work; Cylinder 12 epicoele air inlets, it is descending to make piston motion drive friction clutch shift fork 11, and the Hydraulic Pump power-transfer clutch in the double dynamical transmission gearbox 10 of stand alone type automatic switchover combines; Rely on the inertia of vehicle, propeller-shaft drives Hydraulic Pump 7 rotations and oil suction from pressurization thermostatic type fuel tank 9 through friction clutch in the double dynamical transmission gearbox 10 of stand alone type automatic switchover; Simultaneously, the central signal controller sends instruction and gives pressure store controller 2, and inserted valve C2 is opened, and begins accumulation of energy thereby the hydraulic oil of Hydraulic Pump 7 outputs is pressed in the energy storage 4 through C2.When the pressure in the energy storage 4 reaches setting value; Pressure sensor 3 sends signal and gives the central signal controller; Send instruction for respectively pressure store controller 2 and braking back pressure control device 1 through the central signal controller, close the C2 inserted valve and open the C1 inserted valve, cut off the oil circuit of Hydraulic Pump 7 to energy storage 4; Energy storage is in packing state, and the hydraulic oil of Hydraulic Pump 7 outputs this moment is drained the oil to fuel tank 9 with the lower pressure of setting through braking back pressure control device 1.
2. during vehicle start; Light accelerator pedal; The throttle shift sensor is passed to the central signal controller with throttle signal, sends instruction through the central signal controller and gives cylinder controller 13 work, cylinder 12 cavity of resorption air inlets; It is up to make piston motion drive friction clutch shift fork 11, and the HM Hydraulic Motor power-transfer clutch in the double dynamical transmission gearbox 10 of stand alone type automatic switchover combines; Simultaneously, the central signal controller also sends instruction and gives pressure store controller 2 and HM Hydraulic Motor governor 5, and inserted valve C3 and C4 are opened, thereby makes the pressure oil in the energy storage 4 get into HM Hydraulic Motor 8 through C3 and constant pressure device 6 with certain pressure.HM Hydraulic Motor 8 rotates under the effect of pressure oil, and automaticallyes switch in the double dynamical transmission gearbox 10 through stand alone type that the friction characteristics on hydraulic motor power-transfer clutch passes to propeller-shaft with moment of torsion and powered vehicle is advanced.The hydraulic oil of discharging from HM Hydraulic Motor 8 gets into HM Hydraulic Motor governor 5, gets back to pressurization thermostatic type fuel tank 9 through the C4 inserted valve that has configured and forms first kind of acceleration/accel; When vehicle reaches certain speed of a motor vehicle; The central signal controller sends instruction and gives HM Hydraulic Motor governor 5, and inserted valve C5 opens, and hydraulic oil is got back to pressurization thermostatic type fuel tank 9 through inserted valve C5 and formed second kind of acceleration/accel; When vehicle reaches certain moving velocity; The central signal controller sends instruction and stops operating for HM Hydraulic Motor 8, and vehicle gear box advances third gear, normal vehicle operation.
