Below in conjunction with the accompanying drawing narration detailed to the present invention
As shown in Figure 1, gas control is actuated brake pedal apparatus, and high speed double-acting cylinder anthropomorphic dummy leg-training can realize stepping on brake pedal.Because of the path of motion of brake pedal is one section camber line, so variation has all taken place for the knee joint of people's leg and ankle joint angle.Coupling end has all adopted articulated mounting about the high speed double-acting cylinder for this reason, and the upper end is fixed on the driver's seat by articulated stand on the cylinder and supporting plate.Rigidity for stiffened cylinder upper end attachment point prevents the back seat phenomenon when cylinder is actuated, and has adopted snap close permanent seat and restraint zone that planker is anchored on the driver's seat fully.The cylinder lower end is by jointed shaft under the cylinder, adapter plate, pedal anchorage bar are connected on the brake pedal above the brake pedal.Bigger for solving high speed double-acting cylinder upper and lower side span, cylinder poor rigidity and the cylinder rod that causes is released and the clamping stagnation problem of retraction has increased strut bar and strut bar fixed support.More than actuate the mechanical connecting part of brake pedal apparatus for gas control.The moving part of gas control and shortness of breath comprises high-voltage energy storage inflator, energy storage inflator compression indicator, air pressure adjustment control box, supply air line and cylinder is actuated admission port, cylinder is retracted into gas port, according to Fig. 2 this is described in detail.
Pressure regulating valve among Fig. 2, compression indicator, manually actuated control valve and air pressure guide control change-over valve and unify to be integrated in the air pressure adjustment control box among Fig. 1.The constant air pressure of pressure regulating valve output is divided into two-way, and one the tunnel as controlling the manually actuated control valve that air pressure enters two five-ways, according to diverse location output pressure on different paths of control handle, and becomes the commutation control signal that the air pressure guide controls change-over valve.Another road is controlled in the change-over valve as actuating the air pressure guide that air pressure enters two five-ways, commutation control signal according to the manually actuated control valve input determines to actuate the admission port that air pressure enters that end band quick exhaust valve of high speed double-acting cylinder, to realize car brakeing or brake off by cylinder.
Its principal character is as follows as can be known to sum up Fig. 2:
1, can realize the Long-distance Control brake pedal.Testing crew at car copilot seat or back row seats can realize that all Long-distance Control high speed double-acting cylinder brakes or brake off, with the brake test effect of realizing ideal;
2, the brake pedal force that testing crew can be is as required regulated and is actuated air pressure and show concrete pressure value;
3, constant bidirection press is exported.As long as the predefined air pressure numerical value of air pressure adjustment control setup is lower than the certain pressure numerical value in the high-voltage energy storage inflator, promptly exportable constant atmospheric pressure value, thus guarantee stable brake pedal force, so just guaranteed the repeatability of brake test;
4, brake response time is short.In the high strength brake test, require the brake activation treadle effort time very short, adopted high speed double-acting cylinder and quick exhaust valve, it is basic identical to have guaranteed that gas control is actuated the treadle effort reaction time that brake pedal apparatus and chaufeur apply.
The present invention includes the hinged securing device of hinged securing device, cylinder and the brake pedal of high-voltage energy storage device, air pressure regulator, manual control device, gas control reversing arrangement, pressure-display device, high speed double-acting cylinder, rapid exhaust, cylinder and driver's seat.The high-voltage energy storage device can carry with car, the storage high pressure gas, and, damage closed-center system when preventing to replenish high pressure gas with compression indicator demonstration high pressure gas numerical value; Air pressure regulator, manual control device, gas control reversing arrangement, pressure-display device all compact set are formed in air pressure adjustment control box inside, its with the input one-way high-pressure gas is output as two-way, pressure is controlled and constant high pressure gas.The high pressure gas of air pressure adjustment control box output are input to high-speed cylinder, and it is response release cylinder bar fast, actuate brake pedal and finish once braking.Constant because of the input air pressure of high-speed cylinder, guaranteed fixing treadle effort of brake pedal output like this.And the input air pressure size and Orientation of high-speed cylinder by testing crew in copilot seat control and regulation, like this testing crew just can according to brake test needs Long-distance Control when brake activation, when brake off reaches the size of at every turn stepping on brake pedal force.
In addition among Fig. 1 above the brake pedal adapter plate be designed to the plane, adopting head is that the pedal anchorage bar of countersunk-heat bolt connects as one adapter plate and brake pedal.Occur under the various emergency case in the brake test process like this, chaufeur also may command brake pedal is braked, to guarantee vehicle and personal security.
