Description
Technical field
Patent of the present invention relates to a kind of automobile gearbox parking device, especially for the parking and braking mechanism of pure electric automobile automatic transmission case.
Background technique
Along with the development of electric vehicle engineering, people are also more and more higher for the requirement of the aspects such as vehicle performance performance, ride comfort, space layout, current most of pure electric automobile is manual parking device, driver is made to have higher labor intensity, comfort level is inadequate, and the existing speed changer parking device complex structure for pure electric automobile parking design, performance are often not good, there is a lot of problems, bring destabilizing factor to the Security of pure electric automobile.
Search Patents document, the arrestment mechanism of similar ratchet, ratchet is all have employed in current most of gearbox parking device, the structure of patent of the present invention is completely different from ratchet, ratchet, patent structure of the present invention proposes first in association area, the mode adopting brake posts to be inserted in brake disc realizes parking, and parking mode is safe and reliable; Simultaneously patent of the present invention overcome due to automobile or braking motor break down cause can not the shortcoming of brake off, can manual brake off, bring convenience to maintenance.
Summary of the invention
The object of patent of the present invention is to provide a kind of pure electric automobile automatic transmission box parking mechanism, there is the advantage that other halting mechanisms do not have, overcome the shortcoming of above-mentioned prior art, realize the simple, convenient, practical of automatic parking, reduce the labor intensity of driver, improve the Security of pure electric automobile parking.
Art solutions of the present invention is: this pure electric automobile automatic transmission box parking mechanism, mainly comprises braking motor, T-shaped guide rail, push rod, leading screw, coupling, brake disc, disk, brake posts; Push rod and T-shaped guide rail form sliding pair, and push rod and leading screw connect to form screw pair, and braking motor drives leading screw to rotate by coupling, thus realizes moving left and right of push rod; When electric vehicle is in parking shelves, push rod can drive disk and spring handle brake posts to be inserted in brake disc and realize gearbox brake, and when being in other gears, push rod returns to initial position, and brake posts exits from brake disc, brake off.
As the curve bath that preferred patent system Moving plate of the present invention has 6 angles to be 30 °, 6 curve baths position decile on the disc brake rotor; The disk corresponding with brake disc there is the brake posts that 5 positions are divided equally, a compression spring is housed between brake posts and disk, when certain brake posts front-end face touch brake disc can not advance time, brake posts can be compressed to inside disk, other brake posts do not contacted move on, when the object that this brake structure designs like this is to stop in any position, can ensure to have at least 2 brake posts to be inserted in brake disc, improve the Security of braking.
The effect that patent of the present invention is useful is: patent of the present invention adopts the power units such as motor to drive, reduce driver's labor intensity, compact structure, easy to manufacture, to stop the speed changer parking device of design for pure electric automobile, when vehicle or braking motor break down, to cause after parking can not brake off state time, manually the bolt in frame can be unclamped, make brake posts throw off brake disc and remove parking braking state.

Fig. 2 is the arrestment mechanism schematic diagram of patent of the present invention.
Fig. 3 is the brake disc schematic diagram of patent of the present invention.
Description of reference numerals: braking motor 1, coupling 2, leading screw 3, push rod 4, disk 5, brake posts 6, spring 7, brake disc 8, gear-box axle 9, T-shaped guide rail 10, brake disc bolt 11, frame 12, frame bolt 13.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, patent of the present invention is further described.
Embodiment: a kind of automatic transmission box parking mechanism that patent of the present invention provides comprises driving mechanism and arrestment mechanism, driving mechanism forms primarily of braking motor 1, coupling 2, leading screw 3, push rod 4, T-shaped guide rail 10; Push rod 4 is stuck on T-shaped guide rail 10 and forms sliding pair, can realize moving left and right; Leading screw 3 and push rod 4 form screw pair; Arrestment mechanism forms primarily of disk 5, spring 7, brake posts 6, brake disc 8.Spring 7 and brake posts 6 are contained on disk 5, can be compressed to inside disk 5 when brake posts 6 is advanced and run into obstacle; Disk 5 is concentric with brake disc 8, can ensure that brake posts is inserted into brake disc 8 li smoothly.
During described mechanism's parking, braking motor 1 is energized, braking motor 1 drives leading screw 3 to be rotated counterclockwise by coupling 2, leading screw 3 is rotated counterclockwise and drives push rod 4 to move near brake disc 8 direction, when disk 5 contacts with brake disc 8, have at least 2 brake posts 6 to be inserted into brake disc 8 li, the gear-box axle 9 be now connected by key with brake disc 8 can not be rotated, limit switch simultaneously on motor controls motor and stops the rotation, and completes the parking process of electric vehicle.
When vehicle start needs to remove parked state, braking motor 1 is energized to reversing and drives leading screw 3 to turn clockwise by coupling 2, leading screw 3 turns clockwise and drives push rod 4 to move to away from brake disc 8 direction, now brake posts 6 is all extracted from brake disc 8, limit switch controls motor stalling, gear-box axle 9 can realize rotating, and vehicle returns to driving states.
In addition, when vehicle or braking motor break down, to cause after parking can not brake off state time, the mode of artificial brake off can be taked, described frame bolt 13 can be backed out, braking motor 1 is outwards hauled out together with push rod 4, disk 5, brake posts 6, brake posts 6 and brake disc 8 are departed from, just can realize brake off, parked state removed by vehicle.
