Description
Technical field
The invention belongs to power transmission system for electric vehicle technical field, the parking electric automobile brake system structure of the safety guard of a kind of slope road parking specifically.
Background technology
The P shelves of automatic gear car are the another kind of safety guards stopping except parking brake Wai Po road, and manual automobile also can by parking brake or flame-out after hang into certain gear and to prevent, slip car phenomenon by Jake brake.Electronlmobil generally includes two class change speed gear boxs, one class is to form by CVT or the AT transformation of the way, one class is the electric drive driving system of developing for electronlmobil specially, the former slope road parking and automatic gear car are in full accord, the latter is actual is the hand-operated transmission only with 1 gear, and the propulsion source drive motor of electronlmobil itself does not have braking function, therefore stop and can only rely on parking brake to realize in slope road, once parking brake is malfunctioning, will impact the safety of car load, in addition emergency brake system only allows vehicle to stop rear use completely conventionally, the present invention causes damage for preventing that chaufeur maloperation or misoperation from can hang into P gear Er Buduigai mechanism in Vehicle Driving Cycle.
Summary of the invention
The parking electric automobile brake system structure that the object of this invention is to provide a kind of slope road parking safety guard.
The object of the present invention is achieved like this, a kind of parking electric automobile brake system structure, it includes gear arm, locking pin, shifting disc, oil sealing is controlled in parking, parking actuating spindle, locking bar support arm, output shaft ratchet, it is characterized in that: gear arm passes through locking pin, parking actuating spindle is fixedly connected with locking bar support arm, fixedly be located at the shifting disc that has four gear grooves on parking actuating spindle, parking actuating spindle between shifting disc and locking bar support arm is also provided with a pad being connected with this structure housing, described shifting disc contacts with leaf spring by roller, locking bar support arm supports mutually with the locking bar with vee-block, leaf spring and vee-block are fixed on the housing of this structure by locating dowel pin respectively, between locking bar and output shaft ratchet, be also provided with a ratchet with torsion spring and ratchet S. A..
Parking electric automobile brake system advantage of the present invention: according to transmission system of electric automobile feature, designed emergency brake system, met the quiet dynamic parking requirement of car load.Concrete technical characterstic:
1, with respect to existing electronlmobil in the market, rely on merely the road parking of parking brake slope, the present invention is that electronlmobil increases Liao Po road emergency brake system, can play safety protection function;
2, static parking function intensity is high, and car load is fully loaded with quality≤1800kg, and the electronlmobil of the gradient≤30% all can meet
Performance and requirement of strength;
3, project organization is compact, in the situation that guaranteeing axial installation length 28mm, increases braking during standstill system on fore shell
System attachment point;
4, meet dynamic parking requirement, emergency brake system only allows vehicle to stop rear use completely conventionally, and the present invention causes damage for preventing that chaufeur maloperation or misoperation from can hang into P gear Er Buduigai mechanism in Vehicle Driving Cycle.When speed of a motor vehicle > 3km/h hangs after P gear, ratchet can be deviate from automatically between ratchet two gear teeth, can not play parking effect, prevents that vehicle high-speed from suddenly stopping car load impacting; When the speed of a motor vehicle≤3km/h hangs into P gear, ratchet can not deviate between ratchet two gear teeth again, plays parking effect, and emergency brake system can not be damaged;
5, reliability is high, range of use is wide, the present invention is stroke lengthening hybrid power automobile exploitation, because this vehicle has two cover power systems, complete vehicle weight is much larger than electronlmobil and traditional fuel-engined vehicle, therefore this invention can meet electronlmobil operating needs completely, the advantages such as the present invention has safe and reliable, applied range.

Below in conjunction with accompanying drawing, by example, the present invention is described in further detail, but following example is only the present invention's example wherein, do not represent the rights protection scope that the present invention limits, the scope of the present invention is as the criterion with claims.
The specific embodiment
example 1
Shown in Fig. 1～2, in figure 1 is gear arm, 2 is locking pin, 4 is shifting disc, 3 is parking control oil sealing, gear arm 1 is fixedly connected with locking bar support arm 6 by locking pin 2, parking actuating spindle 14, fixedly be located at the shifting disc that has four gear grooves 4 on parking actuating spindle 14, parking actuating spindle 14 between shifting disc 4 and locking bar support arm 6 is also provided with a pad 13 being connected with this structure housing, described shifting disc 4 contacts with leaf spring 5 by roller, and locking bar support arm 6 supports mutually with the locking bar 11 with vee-block 7; Leaf spring and vee-block are fixed on the housing of this structure by locating dowel pin 12 respectively; Between locking bar 11 and output shaft ratchet 10, be also provided with a ratchet with torsion spring and ratchet S. A..
Principle of work: electric drive driving system and drive motor are rigidly connected by spline, itself only possesses P shelves function, do not have other shift function, but for realizing whole automobile control function, gear arm still exportable 4 PRND gears to the gearshift of operator's compartment, gearshift output gear signal is to entire car controller and electric machine controller, the reversion of R gear drive motor realizes reversing, N gear drive motor is exported without moment of torsion, D gear drive motor forward, when electronlmobil stops, gear is when park, ratchet will snap in the middle of ratchet two teeth, parking lock is by electric drive driving system output shaft locking, now wheel is in mechanical locking state, can prevent from slipping.
Described gear arm 1, shifting disc 4 and locking bar support arm 6 are to be all connected by locking pin 2 and parking S. A. 14, on shifting disc, there are four gear grooves to represent respectively PRND gear, on leaf spring 5, by roller, contact with shifting disc 4, leaf spring 5 and vee-block 7 are fixed on fore shell by locating dowel pin 12 and bolt respectively, shifting disc 4 and locking bar support arm 6 coordinate by pad 13 and housing, locking bar support arm 6 plays the locking bar effect of supporting, ratchet 8 can rotate freely around torsion spring and ratchet S. A. 9, between ratchet and S. A., has torsion spring to play reset role.
When chaufeur Po road, stop and hang the gear into P, gear-shifting inhaul cable drives gear shift arm 1 to rotate, parking actuating spindle 14, shifting disc 4, locking bar support arm 6 rotate thereupon, leaf spring 5 moves to P gear draw-in groove from shifting disc D gear draw-in groove along shape line, gear shifting force is determined by leaf spring 5 rigidity and shifting disc 4 shape lines, the rotation of locking bar support arm 6 drives on locking bar 11 and moves, locking bar 11 conical surfaces contact with vee-block 7, under the guiding of vee-block 7, contact with ratchet 8, drive ratchet 8 to snap between 10 liang of teeth of output shaft ratchet, play parking function.When chaufeur need to rerun car load, from operator's compartment, take parking shelves, leaf spring 5 moves to R, N, D draw-in groove position successively along shifting disc 4 shape lines from P gear groove, locking bar moves down under the drive of locking bar support arm 6, locking bar 11 and ratchet 8 are disengaged, ratchet 8 resets and departs from ratchet 10 under the effect of torsion spring and ratchet S. A. 9, and parking braking function is cancelled.
Part that the present invention does not relate to all same as the prior art or employing prior art is realized.
Fig. 3, Fig. 4 are all the outside three-dimensional simplified schematic diagram of emergency brake system holder housing of the present invention.
