Abstract
The utility model relates to a floor type electronic accelerator pedal which can simulate pedal feeling of a conventional mechanical pedal as well as provide a pedal position signal as an input signal of the vehicle speed and can be applicable to a driving and operating mechanism of various motor vehicles. A mechanism which consists of a pedal, a connecting rod, a sensor moving element and a fixed seat can eliminate an inverse rotation of the pedal around the fixed seat and can convert the rotary motion of the pedal around a pedal shaft of the fixed seat into the equivalent rotary motion of the sensor moving element around a sensor shaft of the fixed seat. Therefore, a friction element, a spring element and a sensor element can be arranged on the sensor shaft away from the pedal shaft. The utility model increases the flexibility of the sensor, reduces damages to the sensor which is caused by operation mistake. A lever-shaped sensor moving element can drive a compression spring and a friction plate to simulate a retardance feeling of the mechanical pedal.
Description
Affiliated technical field
The utility model is a kind ofly can simulate the work of traditional mechanical acceleration pedal, can be the floor type efp of electric signal with the angle change transitions of pedal travel again.Be mainly used in the speed of a motor vehicle steering unit of various automobiles and power actuated vehicle.Acceleration pedal as passenger vehicle.
Background technology
Das Gaspedal is the input media of the chaufeur control speed of a motor vehicle.Traditional mechanical Das Gaspedal can directly be regulated the position of throttle gate to reach the purpose of the control speed of a motor vehicle by drag-line.The novel electronic Das Gaspedal only provides pedal position signal to control Throttle Position indirectly as the incoming signal of engine management system, finally reaches the purpose of the control speed of a motor vehicle.Efp need be arranged spring element and friction element to simulate the pedal sense of traditional mechanical pedal, needs position transduser simultaneously again the position transition of pedal is become position signal.Efp can adopt suspension type to be installed on the operator's compartment fireproof brickwork, and pedal shaft and chaufeur pin distance are far away, therefore arrange that corresponding spring element, friction element and sensor are more convenient.Chinese patent ZL200420012064.5 vehicle electronics and mechanical Das Gaspedal universalization structure are the utility models at this suspension type pedal.The floor type efp then will be directly installed on the cab floor, and the distance and position of pedal shaft and chaufeur pin is nearer.Therefore the floor type pedal can not be as suspension type directly be arranged in sensor on the pedal shaft and damages sensor with the misoperation of avoiding the chaufeur pin.China Patent No. ZL03271987.6 electricity-controlling throttle pedal directly is arranged in sensor axis on the pedal, only has a revolute pair to be connected between pedal and the firm banking, and pedal may take place around this revolute pair backwards rotation during driving.Simultaneously, on clutch pedal retrun spring, can not simulate traditional pedal sense exactly owing to use wind spring in the above-mentioned patent.
Summary of the invention
In order to overcome near the mounting spring element S. A. of existing floor type pedal, the deficiency in the space of friction element and angular transducer, avoid the misoperation of chaufeur pin and damage sensor, improve pedal sense, and the backwards rotation of elimination pedal and base, the utility model provides a kind of floor type efp design plan.This utility model with pedal S. A. and sensor axis separately and is utilized the principle of four-bar linkage, will transfer to away from the rotatablely moving of the sensor axis of pedal shaft around the rotational motion equivalence of pedal shaft, has solved the space problem of said elements assembling.And increase by two members and two revolute pairs between pedal and the base, and constitute four-bar linkage, eliminated the backwards rotation of pedal around this base.And be lever construction with the sensor movement component design, utilize this to be configured in the compression-type clutch pedal retrun spring of packing in the floor type pedal, improved the force characteristic of Das Gaspedal, simulate traditional pedal sense more accurately.
The technical scheme that its technical matters that solves the utility model adopts is: the floor type efp is mainly by pedal, connecting rod, and firm banking, the sensor movement parts, sensor fixed parts and spring, component piece and friction lining are formed.Firm banking is designed to hull shape, arranges two S. A.s in firm banking, one is that sensor axis is pedal shaft with another.The pedal root has the pedal axle sleeve, and at the middle part of pedal design deck.By bearing pin pedal is connected at the pedal shaft place with firm banking, and pedal can be relatively rotated around pedal shaft with respect to firm banking.The sensor movement parts can be assemblied on the sensor axis of firm banking, and can rotate around sensor axis.The sensor movement parts are designed to the lever shape of fulcrum at the middle part, and an end is a drive end.Connecting rod one end is connected on the deck at pedal middle part, and the other end snaps onto the drive end of sensor movement parts.Like this, pedal, connecting rod, the equivalent transformation that rotatablely moves that the mechanism that sensor movement parts and firm banking constitute can wind pedal with respect to the firm banking pedal shaft is the motions of sensor movement parts around the firm banking sensor axis.Pedal is owing to backwards rotation around base has been eliminated in the restriction of connecting rod.By this conversion of motion, can being installed on the sensor axis away from pedal shaft of sensor fixed parts.Increased the alerting ability of placement sensor like this, improved the installing space of sensor and avoid the misoperation of chaufeur pin and damage sensor.And assemble compression spring to simulate the traditional mechanical treadle effort more accurately at the other end of lever shape sensor movement parts.By the component element spring force is decomposed into the pressure of friction lining toward base housing wall producing the pedal drag, and another part component simulation treadle effort can be simulated pedal sense so all-sidedly and accurately.
The beneficial effects of the utility model are, can be with friction element, spring element and sensor element are arranged in the sensor axis away from the pedal S. A., by lever compression spring power is passed back to pedal at the sensor axis place, both can simulate mechanical treadle effort sensation simply exactly, increased the alerting ability of the layout of sensor again, and reduced to damage the possibility of sensor owing to the misoperation of chaufeur pin.Pedal and firm banking increased connecting rod with this eliminated pedal around the backwards rotation of base may.
