Description
Technical field
The utility model relates to a kind of small-sized electric car acceleration brake system steering unit, particularly a kind of small-sized electric running braking (brake) and the acceleration brake system steering unit of braking during standstill by same pedal realization.
Background technology
Shortcomings such as in the existing automobile-used acceleration brake system steering unit, service brake is controlled by different steering units with braking during standstill, exists mechanism complicated, and part count is many.
Summary of the invention
The utility model provides a kind of small-sized electric car acceleration brake system steering unit, and this mechanism makes in the driving procedure operation easier, and mechanism is simpler.
For reaching the foregoing invention purpose, the utility model adopts following technical scheme:
This small-sized electric car acceleration brake system steering unit; It comprises: brake rotating shaft (2), be fixed on that brake pedal (1), the axle of brake in the rotating shaft is provided with brake permanent seat (3), spacing bump rubber (4) brakes; The brake rotating shaft is provided with brake adjustment bar (5); The brake rotating shaft be provided with Parking ratchet (6), the brake rotating shaft an end be provided with accelerator (9), acceleration pedal (7) is fixed in accelerator (9) rotating shaft through screw and park pawl (8); The Parking ratchet cooperates with park pawl (8), in the accelerator (9) once the position torsion spring.
Described brake pedal is fixing through taper hole and brake rotating shaft (2);
Described Parking ratchet (6) is to be fixed in the brake rotating shaft through flat key, back-up ring.
For mating different required braking forces, improve system life, be provided with 2 braking during standstill gears; Two draw-in grooves promptly are provided on the Parking ratchet; When park pawl during in different screens, the brake cable tensioning degree is different, and braking force is respective change also; One grade supplies the level land Parking to use, and one grade supplies the ramp Parking to use.
The utility model advantage is: same pedal is used in service brake and Parking, has cancelled the Parking pedal, brake that can the accuracy control vehicle, level land Parking, ramp Parking, walking one of four states.

Among Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,1 is brake pedal, and 2 are the brake rotating shaft, and 3 are brake rotating shaft permanent seat; 4 are the spacing bump rubber of brake, and 5 is the brake adjustment bar, and 6 are the Parking ratchet, and 7 is acceleration pedal; 8 is park pawl, and 9 is accelerator, and 10 is bolt of rear end plate, and 11 is riveting nut.
The specific embodiment
Brake pedal 1 is fixing with brake rotating shaft 2 through taper hole; Brake permanent seat 3 is fixed on whole operating mechanism on the vehicle frame; Spacing when the spacing bump rubber 4 that brakes is used for brake pedal and brake rotating shaft free state; To the brake rotation of rotating shaft 2 of brake adjustment bar 5 is converted into the tensioning displacement of brake cable; 6 are the Parking ratchet, are fixed in the brake rotating shaft through flat key and back-up ring, and 7 is acceleration pedal; Be fixed in accelerator 9 rotating shafts through screw and park pawl 8, position torsion spring once in the accelerator 9 guarantees that acceleration pedal 7 and park pawl 8 be not when receiving external force; System keeps initial condition; 10 is the fastener in the mechanism, 11 for and the riveting nut that is fixed on the vehicle frame, for the installation of total system provides support.
Ratchet 6 and brake pedal 1 interlock in the system, ratchet 8 and acceleration pedal 7 interlocks, when trampling brake pedal 1,5 displacements of brake cable adjust bar increase gradually, brake shoe brake cheek tensioning gradually in the drg, braking force increases;
When brake pedal was stepped on certain angle, ratchet 8 will get into the corresponding screens on the ratchet 7, kept the shift invariant of brake cable adjust bar 5, to car load constant braking force was provided.
When car load needs brake off, double ring ahead; Light stepping on accelerator pedal 7; Then ratchet break away from ratchet 7 on screens, brake pedal 1 and with brake rotating shaft 2 on all parts of assembling all because the influence of returning place force is got back to initial condition, the brake shoe brake cheek return; Car load no longer receives braking force, and parking function is released.The rotation of acceleration pedal 7 is that accelerator 9 provides motor drive signal simultaneously, and car load to overtake.
The operating process of native system is:
Free state
Mechanism's state is as shown in Figure 2, the both brakings of car load this moment, and also double ring ahead not, system is in free state, and this state is a kind of transition condition, less appearance in the normal use of vehicle.At this moment, the work tooth A of park pawl since accelerator return torsion spring returning place force, abut against on the driving surface of Parking ratchet a.
The service brake state
When vehicle in the process of moving, when need slowing down, mechanism's state is as shown in Figure 3.
Level land Parking state
Mechanism's state is as shown in Figure 4, and this moment, brake pedal rotated certain angle, and ratchet work tooth gets into ratchet first screens, provides the Parking of vehicle level land required braking force.
Ramp Parking state
Mechanism's state is as shown in Figure 5, and the ramp Parking needs bigger braking force, and this moment, brake pedal rotated more perspective, and ratchet work tooth gets into ratchet second screens, and the brake shoe brake cheek tensioning degree increases, and braking force increases.
The double ring ahead state
When car load needs brake off, double ring ahead, light stepping on accelerator pedal, the then screens on ratchet disengaging and the ratchet, brake pedal 1 is got back to initial condition, and brake shoe brake cheek return, car load no longer receive braking force, and parking function is released.The rotation of acceleration pedal simultaneously provides motor drive signal for accelerator, and car load to overtake.Mechanism's state is as shown in Figure 6.
