Abstract
The utility model is a kind of brake pedal for improving vehicle and braking resilience sensor signal reliability, including pedal, pedal is mounted on by pedal arm rotation center on bracket assembly, running through in the pedal arm rotation center has axis pin, needle bearing one and needle bearing two are wherein cased on the both ends of axis pin respectively, then grade ring two and shelves ring one are respectively equipped with outside needle bearing one and needle bearing two；Gasket is externally provided in shelves ring two, axis pin is externally provided with Hall sensor.The utility model redesigns processing axis pin, cancels wear resistant nylon nested structure, and axis pin is changed to the use structure of rolling friction pair combination shelves ring that both sides support by rolling bearing.Abnormal sound is eliminated during brake operation；Hall sensor signal meets reliability brake service life average out to 3,500,000 times of VCU service precisions or more, meets the life requirements that vehicle uses, 30,000 kilometers of road test electric vehicle vehicle brakes are without exception.
Description
Technical field
The utility model is related to the braking of vehicle, specifically a kind of vehicle that improves brakes resilience sensor signal reliability
Brake pedal.
Background technology
There is entire car controller once in a while after travelling certain mileage in 30,000 kilometers of road test test feedbacks of electric vehicle（Abbreviation VCU）
Level fault brakes abnormal alarm, and there are abnormal sounds during brake operation, are that nylon jacket eccentric wear is braked in braking pin shaft through investigating main cause
Resilience signal, which surpasses tolerance, to be caused.
Current electric vehicle brake pedal is as shown in Fig. 4/5/6.
1 is bracket assembly in figure, and 2 be pedal, and 3 be pedal arm rotation center, and 4 be wear resistant nylon gum cover, and 5 be axis pin one, 6
It is grade ring one, 7 be grade ring two, and 8 be gasket, and 9 be Hall sensor.
Braking resilience sensor is Hall sensor 9 used by electric vehicle brake pedal, and pedal 2 is mounted on bracket assembly
On 1, wear resistant nylon gum cover 4 being wherein installed in pedal arm rotation center 3, axis pin 1 is applied in wear resistant nylon gum cover 4, and
It is fixed equipped with shelves ring 1, shelves ring 27 and gasket 8, Hall sensor 9 is then mounted on the end of axis pin 1.
The angular displacement signal that VCU needs is derived from Hall sensor 9 herein, reappears monitoring, signal through being tested with machine part
Meet the reliable life average out to 180,000 times of VCU service precisions, be unable to reach automobile reliability requirement and service life.
Invention content
For the utility model in order to reach automobile reliability requirement and prolong the service life, spy proposes a kind of raising vehicle
Brake the brake pedal of resilience sensor signal reliability.
The technical solution of the utility model is a kind of brake for improving vehicle braking resilience sensor signal reliability thus
Pedal, including pedal, pedal is mounted on by pedal arm rotation center on bracket assembly, it is characterised in that：The pedal arm rotation
Turn wherein to be cased with needle bearing one and needle bearing two on the both ends of axis pin respectively, then in needle roller axis through there is axis pin in center
It holds and is respectively equipped with grade ring two and shelves ring one outside one and needle bearing two；Gasket is externally provided in shelves ring two, axis pin is externally provided with Hall biography
Sensor.
Advantageous effect：
The utility model redesigns processing axis pin, cancels wear resistant nylon nested structure, axis pin is changed to both sides by rolling
The use structure of the rolling friction pair combination shelves ring of bearing bearing.Abnormal sound is eliminated during brake operation；
Hall sensor signal meets VCU service precisions, and reliability brake service life average out to 3,500,000 times or more meets vehicle
The life requirements used, 30,000 kilometers of road test electric vehicle vehicle brakes are without exception.
