Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the present invention is done detailed explanation.
Consult Fig. 1-Fig. 2, the automatically controlled P retaining device of used for electric vehicle of the present invention is made of gear shaft (1), locking wheel (2), locking pawl (3), support bearing pin (4), unlock signal switch (5), casing (6), pull bar (7), nut (8), power motor (9), axle sleeve (10), locked signaling switch (11) and P retaining signaling switch (12);
The corresponding tooth of profile of tooth of taking turns (2) with locking is arranged on the locking pawl (3), and locking wheel (2) is fixed on the gear shaft (1) of retarder;
The locking pawl has waist through hole on (3), is provided with in this through hole to support bearing pin (4), forms Spielpassung between them, supports bearing pin (4) and is fixedly mounted on the casing (6);
Locking pawl (3) and pull bar (7) the formation assembly parts that is fixed together, pull bar (7) are by the support of the axle sleeve (10) in casing (6) hole, and pull bar (7) forms Spielpassung with axle sleeve (10);
Screw portion gone up by pull bar (7) and nut (8) is formed the spiral motion pair, converts rotatablely moving of nut (8) to pull bar (7) move axially; Power motor (9) is fixed on the casing (6), and the output shaft of power motor (9) adopts fixedly connected mode with nut (8).
(can correctly reflect the position that the locking pawl is locked fully and be totally released) on the correct position of casing locked signaling switch (11) and unlock signal switch (5) are housed, unlock signal switch (5) and locked signaling switch (11) are formed the signal feedback system of the mobile position of locking pawl (3); P retaining signaling switch (12) is contained in the automobile bar place of putting into gear.
Consult Fig. 1, locking wheel, locking pawl, supporting pin are formed the lockable mechanism to gear shaft, locking wheel can be involute spur gear, also can be the ratchet of other uniform fluted body, it is corresponding that profile of tooth on the locking pawl goes up profile of tooth with the locking wheel, the locking wheel is fixed on the suitable gear shaft of speed variable device, each one is fixed on the deceleration box about supporting pin, with the two waist type grooves formation Spielpassung of locking pawl; Locking pawl and pull bar are the assembly parts that is fixed together; The hole of draw piece and deceleration box forms Spielpassung under a lining of axle sleeve; The composition bolt kinematic pair of screw portion and nut converts rotatablely moving of nut to draw piece move axially on the pull bar; Power motor is a direct current generator, is fixed on the reduction-gear housing, and its shaft adopts fixedly connected with nut, power motor can be brush motor or brushless electric machine, also can be slowspeed machine or reducing motor, and other electric power motor, for rotatablely moving of nut provides power; Unlock signal switch (part 5) and locked signaling switch (part 11) are equipped with in the appropriate location of deceleration box, form the signal feedback system of the mobile position of locking pawl; P keeps off signaling switch (part 12), is contained in the put into gear appropriate location of bar of automobile, sends the work order of " P retaining " state and " non-P retaining " state according to the position of the bar of putting into gear.
